Cancer and Inflammation, No. 256

Chronic inflammation predisposes to some forms of cancer and the host response to malignant disease shows several parallels with inflammation and wound healing. The cells involved in inflammation are detected in a range of common cancers, together with the inflammatory cytokines and members of the chemokine ligand/receptor systems.

Neutralization or deletion of the gene for some inflammatory cytokines confers resistance to tumour induction and experimental metastasis. Over-expression of such cytokines in tumour cells may enhance malignant potential. Certain chemokines are likely to subvert antitumour immunity by favouring development of ineffective Type 2 responses. Tumour cells may even utilize chemokine receptors in homing to lymph nodes and other organs. Thus, the cells, cytokines and chemokines found in tumours are more likely to contribute to tumour growth, progression and immunosuppression than they are to mount an effective host antitumour response.

This book draws together contributions from an international group of scientists and clinicians from diverse disciplines, ranging from epidemiology to immunology, cell biology, molecular oncology, molecular medicine and pharmacology to debate these and related issues. Topics covered include the epidemiological links between cancer and inflammation, the parallels between inflammation and cancer, the role of inflammation in cancer, inflammatory genes as risk factors for cancer initiation and progression, inflammation and cancer angiogenesis, and preventative and therapeutic strategies.

Cancer Research in Flames
Tracking inflammation's role in promoting malignancy could lead to better treatments by Michael Karin  The Scientist 2005, 19(23):24  Published 5 December 2005

One problem with the current war on cancer is that much of it focuses on destroying the malignant cell itself while paying little attention to some of cancer's allies that are more prone to attack.

Anti-Inflammatory Therapeutics

May Provide Secondary Benefits for Cancer

Nearly 150 years ago, the German physician Rudolph Virchow first proposed a connection between inflammation and cancer. Noting that cancerous tissue also contains the cells and factors that are hallmark features of the body's inflammatory response, Virchow hypothesized that cancer begins at sites of chronic inflammation. At the time - and for many years to follow - the scientific community disavowed this idea because few could envision how the body's first line of defense against tissue injury and infection could also cause harm.

Over the past decade, however, scientists have uncovered increasing evidence to support Virchow's claim. They have determined that the very factors recruited by the body to prevent infection and encourage healing at an injured site can misfire and produce damage. And, if the triggering bacteria, virus, or chemical irritant lingers in the body, a state of chronic inflammation can arise.

Today, research indicates that chronic inflammation underpins a host of diseases, including cancer:

But the most established and elucidated connection between chronic inflammation and cancer is with colorectal cancer.

Drug Therapy Establishes the Link
Evidence supporting a link between chronic inflammation and colon cancer came together from multiple paths of scientific discovery. For years, scientists observed that patients with long-term chronic inflammatory bowel disease, a group of disorders causing chronic and recurring inflammation of the intestines, often develop colorectal cancer. Population studies confirmed this association.

At the same time, scientists studying the effects of non-steroidal anti-inflammatory drugs (NSAIDs) were also finding evidence to support this link. NSAIDs, which include aspirin, are among the oldest and most widely used drugs in history.

The weight of this collective evidence prompted various research teams throughout the country to explore how NSAIDs act on the body and how this action results in reduced polyp growth and colon cancer risk.

The Search for a Common Thread
With a chemically diverse group of drugs like NSAIDs sharing the same therapeutic qualities and adverse side effects, it was assumed that they also share a common mode of action. The activity of these drugs was determined in 1971 when Dr. John Vane and his colleagues demonstrated that aspirin and all NSAIDs restrict inflammation by inhibiting the body's production of
prostaglandins. Vane predicted that NSAIDs accomplish this outcome by blocking the activity of the cyclooxygenase (COX) enzyme, which catalyzes a key step in prostaglandin synthesis.

Vane's Nobel Prize-winning discovery paved the way for future studies confirming the role of COX enzymes in prostaglandin production, and ultimately for the development of drugs that treat inflammatory diseases by blocking the activity of the enzymes. At first, scientists knew of only one COX enzyme. In 1990, however, three research teams became interested in a protein produced by cells that were becoming cancerous.

Scientists recognized that NSAIDs reduce inflammation by blocking the actions of the COX-2 protein, making them potent treatments for inflammation-associated diseases like arthritis. But they still did not have the findings to document why these anti-inflammatory agents reduce colorectal cancer risk. In 1994, a key piece to this puzzle - the link between COX-2 and colorectal tumors - was provided by Charles Eberhart and Raymond DuBois, who observed that COX-2 (but not COX-1) levels are elevated in as many as 80 percent of colorectal tumors. This finding, since replicated by animal studies, suggests a role for COX-2 and inflammation in tumor development.

Promising Therapies and Future Paths
The potential of NSAIDs as chemoprevention agents for colon cancer is considerably limited by the fact that these drugs can cause serious adverse effects. Because they block the actions of both COX proteins, dosing can lead to excessive stomach acid production, ulceration, and gastrointestinal bleeding.

Scientists thought that a better chemoprevention drug would need to selectively target only the COX-2 enzyme, thereby reducing the most harmful effect of NSAIDs while capitalizing on their benefits. In a milestone NCI-sponsored cancer prevention trial, researchers reported on such a drug, celecoxib, an arthritis medicine that selectively targets the COX-2 enzyme, substantially reducing the number of polyps in patients with an inherited disorder of the colon and rectum that causes polyp growth and almost always progresses to cancer.

Recent studies suggest that elevated levels of COX-2 may contribute to the development of tumors originating at other sites in the body, including the breast, skin, lung, esophagus, bladder, cervix, head and neck, stomach, liver, and pancreas. Based on this information, through 11 clinical trials, scientists are now working to determine if these tumors may be vulnerable to the effects of COX-2 inhibitors.

More recently, three research teams found that daily intake of low doses of aspirin reduced the recurrence of colon polyps among people with previous colon cancers or polyps. These data suggest that daily aspirin may be an appropriate supplement to regular surveillance procedures in individuals who have an increased risk for colon cancer that is similar to the level of risk among the trial participants. It is important to note that:

Summary of Meeting
Our appreciation of the complexity of tumor biology has led us from considering tumors as autonomous masses of mutant cells to an awareness of tumors as entities that can hijack and exploit various normal physiologic processes of the host. The frequent presence of inflammatory cell infiltrates and chemical mediators of inflammation in tumors has been recognized for over a century, although an understanding of their role during cancer development has been elusive. Leukocytic infiltrates and cytokine/chemokine networks in premalignant tissues and tumors can be distinct, depending upon the stage of malignant development and organ microenvironment. Current thinking is that activated immune cells provide both anti- and pro-tumorigenic signals, thus representing targets to be harnessed or attacked for therapeutic advantage depending upon environmental and/or cellular context. T lymphocytes are being exploited for their ability to induce tumor regression, as are strategies that disable innate immune cells or neutralize immunosuppressive or pro-inflammatory microenvironments. Such approaches may also provide clinical benefit for at-risk cancer patients and those with pre-malignant lesions. This meeting will link innate and adaptive immune regulatory mechanisms with cancer development and cancer treatment by focusing on relevant basic research, preclinical, translational and clinical studies.

Summary of Meeting
Chronic or recurrent inflammation is responsible for the development of many human cancers, including those affecting the liver, esophagus, stomach, large intestine, and urinary bladder [Coussens and Werb, [2002]]. Inflammation might influence the pathogenesis of cancers by (i) inflicting cell and genome damage, (ii) triggering restorative cell proliferation to replace damaged cells, (iii) elaborating a portfolio of cytokines that promote cell replication, angiogenesis and tissue repair [Coussens and Werb, [2002]]. Oxidative damage to DNA and other cellular components accompanying chronic or recurrent inflammation could increase risk by increasing the mutation rate. In response to infections, inflammatory cells produce a variety of toxic compounds designed to eradicate microorganisms. These include superoxide, hydrogen peroxide, singlet oxygen, as well as nitric oxide that can react further to form the highly reactive peroxynitrite. Some of these reactive oxygen and nitrogen species can directly interact with DNA in the host bystander cells, or react with other cellular components such as lipid, initiating a free radical chain reaction. If the damage is severe, these compounds can kill host bystander cells as well as pathogens, and can produce DNA damage and mutations among host cell survivors. As a consequence of an acquired defect in defenses against oxidant and electrophilic carcinogens associated with CpG island hypermethylation, normal epithelial cells may acquire a heightened susceptibility to oxidative genome damage in an inflammatory milieu, leading to neoplastic transformation and cancer progression.

Molecular Link Discovered Between Inflammation And Cancer
Main Category: Biology / Biochemistry News
Article Date: 28 Jan 2007 - 20:00 PDT


A team led by biochemists at the University of California, San Diego has found what could be a long-elusive mechanism through which inflammation can promote cancer. The findings may provide a new approach for developing cancer therapies.

The study, published in the January 26 issue of the journal Cell, shows that what scientists thought were two distinct processes in cells - the cells' normal development and the cells' response to dangers such as invading organisms - are actually linked. The researchers, who were also from the Salk Institute for Biological Studies and the La Jolla Institute for Allergy and Immunology, say that the linkage of these two processes may explain why cancer, which is normal growth and development gone awry, can result from chronic inflammation, which is an out-of-control response to danger.

"Although there is plenty of evidence that chronic inflammation can promote cancer, the cause of this relationship is not understood," said Alexander Hoffmann, an assistant professor of chemistry and biochemistry at U.C. San Diego, who led the study. "We have identified a basic cellular mechanism that we think may be linking chronic inflammation and cancer."

Cellular defense is a rapid process compared to cellular development, just as a state's response to terrorist threats is swifter than the construction of new infrastructure. However, in both settings, safeguarding against threats and building structures have certain steps in common and require similar types of workers, or molecules.

Hoffmann referred to the parallel sets of steps in cellular defense and development as "mirror image pathways." His team showed that these pathways are not distinct from one another because they are linked by a protein called p100. They found that inflammation leads to an increase in p100, but that p100 is also used in certain steps in development. Therefore p100 allows communication between inflammation and development.

A small amount of dialogue between inflammation and development is beneficial, say the researchers, akin to how information from anti-terrorism efforts could be useful to crews building the state's infrastructure. On the other hand, the constant influence of defense processes on development is detrimental.

"Studies with animals have shown that a little inflammation is necessary for the normal development of the immune system and other organ systems," explained Hoffmann. "We discovered that the protein p100 provides the cell with a way in which inflammation can influence development. But there can be too much of a good thing. In the case of chronic inflammation, the presence of too much p100 may overactivate the developmental pathway, resulting in cancer."

In the paper, the researchers propose that thinking of the processes of defense and development as part of a single large system "represents an opportunity for therapeutic intervention." For example, it might be easier to break the link between inflammation and cancer by targeting the developmental pathway, rather than the inflammation pathway.

"Many of the developmental signals that cells use are sent outside the cell, so they should be easier to block with drugs than inflammation signals, which tend to be confined within cells," said Hoffmann. "It's more challenging to design drugs that will enter cells."

Because the molecules that play a role in the inflammation and development pathways have been extensively studied for many years, the researchers say that it is surprising to find a new molecule that significantly revises scientists' understanding about the interactions between inflammation and development. They credit their discovery to an approach that combines biochemical techniques and computation.

"Our mathematical model of inflammation and development includes 98 biochemical reactions," said Soumen Basak, a postdoctoral fellow working with Hoffmann. " When we ran the model, it predicted that p100 levels would be elevated for a significant period of time when the inflammation pathway was stimulated. We confirmed the prediction using biochemical techniques with cells in the laboratory."

" The finding is exciting because it means that p100 provides cells with a memory to inflammatory exposure," added Basak, who was the first author on the paper.

Also contributing to the study were Hana Kim, Jeffrey D. Kearns, Ellen O'Dea, Shannon L. Werner and Gourisankar Ghosh from U.C. San Diego, Vinay Tergaonkar and Inder M. Verma from the Salk Institute for Biological Studies, and Chris A. Benedict and Carl F. Ware from the La Jolla Institute for Allergy and Immunology.

The study was supported by the National Institutes of Health, the Leukemia and Lymphoma Society of America and the American Heart Association.

Direct Link Found Between Chronic Inflammation, Colon Cancer

Science Daily Investigators in the A.B. Hancock Jr. Memorial Research Center at Vanderbilt have identified a type of DNA damage caused by chronic inflammation as a potential risk factor for colorectal cancer.

The findings, published this week in the early online edition of the website of the Proceedings of the National Academy of Science (http://www.pnas.org), shed more light on the role that inflammation might play in cancer and suggests that measurement of this type of DNA damage might be useful in assessment and management of a patient's colorectal cancer risk.

"A number of studies have implicated chronic inflammation in the development of cancers, but the specific way that occurs is not clear," said Dr. Lawrence J. Marnett, Ph.D., director of the Hancock Research Center and the Vanderbilt Institute of Chemical Biology.

"These studies suggest a direct link between oxidative stress, like that seen in chronic inflammation, and genetic mutations that cause human disease."

The work reported in PNAS builds on years of research at Vanderbilt into how overproduction of the inflammation-causing enzyme cyclooxygenase-2 (COX-2) may contribute to cancer and conversely, how aspirin-like drugs that block COX-2 might help treat or prevent cancer.

"When the body experiences oxidative stress, molecules called free radicals are produced, and these free radicals can damage cells the cell membrane and the DNA," Marnett said.

The researchers examined a type of DNA damage caused by malondialdehye (MDA), a product of COX-2. The question they wanted to answer was whether the DNA damage would stop with the damaged cell or whether it would cause genetic abnormalities, or mutations, which would be replicated in future cell lines.

They built a DNA molecule that incorporated the MDA-caused damage and inserted that into mammalian kidney cells. After the cells divided, the DNA was recovered from the new cells and examined for mutations.

The researchers found that, indeed, the DNA damage had resulted in a specific type of genetic change called a "frameshift mutation." These mutations delete a small portion of DNA, effectively throwing off the "reading frame" through which the genes' instructions are interpreted and resulting in a protein that doesn't do what it is supposed to do.

Interestingly, these types of mutations are common in an inherited form of colon cancer, Hereditary Non-Polyposis Colon Cancer (HPNCC). This work suggests that these mutations, caused by inflammation and other oxidative stress, might also contribute to colorectal cancer.

Co-investigators in the research include Laurie A. VanderVeen, Muhammed F. Hashim and Yu Shyr, representing the Hancock Research Center, the VICB, the Vanderbilt-Ingram Cancer Center, the Vanderbilt Center for Molecular Toxicology and the Vanderbilt School of Medicine departments of Biochemistry and Preventive Medicine.

Funding for the work was provided by the National Institutes of Health.

The A.B. Hancock Research Center, established in 1972 by the family and friends of A.B. "Bull" Hancock, focuses on prevention and early detection of cancers and is noted for its work in breast and colon cancer. The Vanderbilt-Ingram Cancer Center, a part of Vanderbilt University and Medical Center in Nashville, is the only National Cancer Institute-designated Comprehensive Cancer Center in Tennessee and one of only 39 in the United States. This designation is the highest awarded by the NCI, one of the National Institutes of Health and world's foremost authority on cancer.

Tumor-associated macrophages (TAM) represent the major inflammatory component of the stroma of many tumors, able to affect different aspects of the neoplastic tissue. Many observations indicate that TAM express several M2-associated protumoral functions, including promotion of angiogenesis, matrix remodeling and suppression of adaptive immunity. The protumoral role of TAM in cancer is further supported by clinical studies that found a correlation between the high macrophage content of tumors and poor patient prognosis and by evidence showing that long-term use of non-steroidal anti-inflammatory drugs reduces the risk of several cancers. Here, we discuss evidence supporting the view that TAM represent a unique and distinct M2-skewed myeloid population and a potential target of anti-cancer therapy.

Abstract
Recent data have expanded the concept that inflammation is a critical component of tumour progression. Many cancers arise from sites of infection, chronic irritation and inflammation. It is now becoming clear that the tumour microenvironment, which is largely orchestrated by inflammatory cells, is an indispensable participant in the neoplastic process, fostering proliferation, survival and migration. In addition, tumour cells have co-opted some of the signalling molecules of the innate immune system, such as selectins, chemokines and their receptors for invasion, migration and metastasis. These insights are fostering new anti-inflammatory therapeutic approaches to cancer development.

Aspirin against Cancer – colorectal and elsewhere

Dr Sheehan has an interest in colorectal cancer, the second most common cancer in Ireland. aspirin is of interest to her because it is a cyclo-oxygenase (COX) inhibitor.

COX (which has two forms, COX-1 and COX-2) is one step in the conversion of arachidonic acid to prostaglandins. COX-2 is highly inducible and upregulated in colorectal cancer, 70-80% of which exhibit a 2-50 fold increase in COX-2 expression. It is also expressed in stomach, oesophageal, breast, ovary and skin cancers.

More than 30 published studies provide data on aspirin use in colorectal cancer. Among them are reports of a 40% lower risk of colorectal cancer among regular users of aspirin. In a prospective study, aspirin use 16 times per month reduced the risk of fatal colon cancer by 42%. Giovannucci et al found that 5-9 years of regular use could prevent colorectal cancer in women. Sulindac treatment of patients with familial polyposis (FAP) reduced the number and size of polyps within 9 months. In a familial polyposis mouse model, knock out of the COX-2 gene resulted in significant inhibition in colonic polyp growth. Furthermore, more than 25 animal studies have shown prevention or inhibition of chemically induced adenomas and carcinomas in the colon following treatment with aspirin or NSAIDs.

Several clinical trials are underway to investigate the effects of treating colorectal cancer patients with aspirin. One of the larger studies, funded by the National Cancer Institute in the US, has recruited 900 patients over 4 years. They will investigate whether or not treating patients with 325mgs of aspirin will improve disease free survival. Others are investigating the effects of aspirin and NSAIDs on oesophageal, gastric and lung cancers. The effect of aspirin may be multifactorial, on various growth and pro-angiogenic factors, rather than just on COX.

Dr Sheehan investigated tumours from 76 patients with colorectal cancer diagnosed between 1988 and 1990, were graded for the percentage of cells staining for COX-2. They were subdivided into four subsets - <1%, 1-19%, 20-50%, >50%.

There was a significant association between advanced Dukes stage (a clinical measure of severity of the cancer), lymph node involvement and maximum tumour diameter and COX-2 expression. Patients with tumours in which there was <1% COX-2 staining had much better survival than those with more COX-2 staining.

Dr Sheehan concluded that there was ample evidence to suggest that aspirin reduces the risk of developing colorectal cancer. Selective COX-2 inhibitors are on trial, but it is not known whether they are better than aspirin. It is also possible that aspirin or NSAIDs may be used to treat patients who develop this cancer. The dose and duration of aspirin that is required for treatment remains unclear but the results of clinical trials now underway should provide these answers in the near future.

How Do NSAIDs Exert Their Anti-cancer Effects?

NSAIDs inhibit cyclooxygenase (COX) enzymes and prostaglandin synthases, which is at least partly responsible for their anti-cancer effects. Colon cancers have excessive levels of COX-2, which increases production of PGE2 in colon tumors (Sheehan KM et al 1999), promoting tumor progression (Eberhart CE et al. 1994; Jalving M et al. 2005f; Jalving M et al. 2005g; Oshima M et al. 1996) Rigas B et al 1993). NSAID treatment of cancer cells leads to inhibition of COX enzymes and consequent reduction of levels of prostaglandin E2 (PGE2), which in turn suppresses tumor development (Chan TA et al. 1998b; Jalving M et al. 2005e; Tsujii M et al. 1998). PGE2 regulates cancer cell proliferation by modulating the ß-catenin-axin signaling pathway, which is essential for the development of colorectal cancer (Castellone MD et al. 2005; Jalving M et al. 2005d). PGE2 also regulates cancer cell death (apoptosis) by transactivating the nuclear receptor NR4A2 (Holla VR et al. 2006; Jalving M et al. 2005c). http://www.lef.org/protocols/cancer/colorectal_02.htm

  •                      Inflammation as a common mechanism of disease – While significant breakthroughs have occurred in our understanding of inflammation, research is needed to further understand inflammatory processes. Because inflammation is broadly implicated in many diseases and conditions, this initiative would be valuable in uncovering as-yet-unknown immune mechanisms and mediators of inflammation as well as genetic factors, environmental triggers, and the relationship of inflammation to disease.                             Office of Portfolio Analysis and Strategic Initiatives • National Institutes of Health • Bethesda, Maryland 20892                http://nihroadmap.nih.gov/2008initiatives.asp

    Inflammation is the precursor to many cancers and other degenerative diseases such as arthritis, heart disease, stroke, diabetes and high blood pressure. Early detection of inflammation using Thermography may help prevent many negative health conditions from developing.  http://www.docgeorge.com/Thermography.html   clickhere 

     

    There is another connection-proof between tumor tissue inflammation and cancer :
    Since tumors have / posses / present an inflammatory ( effect / action / component / parameter ) too, near IR ( = thermal ) imaging is being used to indicate their position.
