Regular use of vitamin and mineral supplements could reduce the risk of colon cancer

Could the use of vitamin and mineral supplements in a regular diet help to reduce the risk of colon cancer and protect against carcinogens? A study published in the Canadian Journal of Physiology and Pharmacology (CJPP) found that rats given regular multivitamin and mineral supplements showed a significantly lower risk of developing colon cancer when they were exposed to carcinogens.

Cocoa could prevent intestinal pathologies such as colon cancer

A new study on living animals has shown for the first time that eating cocoa (the raw material in chocolate) can help to prevent intestinal complaints linked to oxidative stress, including colon carcinogenesis onset caused by chemical substances.

Compounds in mate tea induce death in colon cancer cells

Could preventing colon cancer be as simple as developing a taste for yerba mate tea? In a recent University of Illinois study, scientists showed that human colon cancer cells die when they are exposed to the approximate number of bioactive compounds present in one cup of this brew, which has long been consumed in South America for its medicinal properties.

Plant flavonoid luteolin blocks cell signaling pathways in colon cancer cells

Plant flavonoid luteolin blocks cell signaling pathways in colon cancer cells

Luteolin is a flavonoid commonly found in fruit and vegetables. This compound has been shown in laboratory conditions to have anti-inflammatory, anti-oxidant and anti-cancer properties but results from epidemiological studies have been less certain. New research published in BioMed Central’s open access journal BMC Gastroenterology shows that luteolin is able to inhibit the activity of cell signaling pathways (IGF and PI3K) important for the growth of cancer in colon cancer cells.

Simple test to help diagnose bowel and pancreatic cancer could save thousands of lives

A simple online calculator could offer family GPs a powerful new tool in tackling two of the most deadly forms of cancer, say researchers.

Academics from The University of Nottingham and ClinRisk Ltd have developed two new QCancer algorithms, which cross-reference symptoms and risk factors of patients to red flag those most likely to have pancreatic and bowel cancer, which could help doctors to diagnose these illnesses more quickly and potentially save thousands of lives every year.

Scientists develop vaccine that successfully attacks breast cancer in mice

Researchers at Mayo Clinic in Arizona (http://www.mayoclinic.org/arizona/) and the University of Georgia (UGA) have developed a vaccine that dramatically reduces tumors in a mouse model that mimics 90 percent of human breast and pancreatic cancer cases — including those that are resistant to common treatments.

Confirmation that vitamin D acts as a protective agent against the advance of colon cancer

A study conducted by VHIO researchers confirms that a lack of vitamin D increases the aggressiveness of colon cancer

The indication that vitamin D and its derivatives have a protective effect against various types of cancer is not new. In the field of colon cancer, numerous experimental and epidemiological studies show that vitamin D3 (or cholecalciferol) and some of its derivatives inhibit the growth of cancerous cells. Researchers at the Vall d’Hebron Institute of Oncology (VHIO), in collaboration with the Alberto Sols Institute of Biomedical Research (CSIC-UAB), have confirmed the pivotal role of vitamin D, specifically its receptor (VDR), in slowing down the action of a key protein in the carcinogenic transformation process of colon cancer cells. These results are being published in the journal PLoS One.

Tapeworm drug inhibits colon cancer metastasis

First results in mice — clinical trials planned

A compound that for about 60 years has been used as a drug against tapeworm infection is also apparently effective against colon cancer metastasis, as studies using mice have now shown. The compound silences a gene that triggers the formation of metastases in colon cancer. Professor Ulrike Stein (Experimental and Clinical Research Center, a joint cooperation between the Charité Medical Faculty and the Max Delbrück Center for Molecular Medicine, (MDC)) and her research group made this discovery in collaboration with Professor Robert H. Shoemaker of the National Cancer Institute (NCI) in Frederick, Maryland, USA (Journal of the National Cancer Institute, Vol. 103, No. 12, June 17, 2011)*. Plans are already underway with Professor Peter M. Schlag (Charité Comprehensive Cancer Center) to conduct a clinical trial.

A potential novel drug-target for colorectal cancer treatment comes from the brain

Brain-derived protein in colorectal cancer

Porto Alegre, Brazil- Tumor progression is usually ensured by more than one proliferative mechanism. When one of these is shut down by a specifically targeted drug, other mechanisms may emerge. While these events may lead to treatment failure, they may also become an opportunity for researchers to identify novel targets to be further explored. In a paper recently published in the journal Oncology (”BDNF/TrkB content and interaction with gastrin-releasing peptide receptor blockade in colorectal cancer,” Vol. 79, pages 430�, 2011; DOI: 10.1159/000326564) Roesler and colleagues describe a novel potential drug-target in colorectal cancer.

New class of cancer drugs could work in colon cancers with genetic mutation, U-M study finds

15 percent of colorectal cancers have mutation that responds to PARP inhibitors

ANN ARBOR, Mich. — A class of drugs that shows promise in breast and ovarian cancers with BRCA gene mutations could potentially benefit colorectal cancer patients with a different genetic mutation, a new study from the University of Michigan Comprehensive Cancer Center finds.
