Menin Gene Mutation made Insulin Secreting Cells to Proliferate

...xpect the connection between a study about a tumor suppressor and a potential new avenue for treating diabetes,’ he adds. ‘By taking advantage of studying a genetically well-characterized tumor syndrome, MEN1, we set out to understand how the first step of benign tumor development is precisely controlled. The m...

DNA-bound p53 Tumor Suppressor Protein Structure Determined

...dy. "Given the fact that p53 is an important tumor suppressor that is mutated in the majority of human cancers, this will undoubtedly be useful information." Earlier work had shown how p53 binds to DNA as a stand-alone entity, a form that does not represent the natural state of p53 binding to DNA. The present...

A New Approach towards Anti-Cancer Drugs

...l. p53 is the guardian protein and is the tumor suppressor protein. Hence the lead researcher Dr. Kathryn Ball said that anti cancer drugs should be targeted against the MDM2 protein. The study has also pointed out a number of protein fragments which has the ability to bind to the MDM2 protein and inhibit it...

p53, the Guardian of Our Genome

p53 is a tumor suppressor gene which was identified by Professor Sir David Lane of Dundee University in 1970.// Experiments done on this gene using the mice model shows that the gene keeps cancer at bay and also alters the ageing process. Larry Donehower of Baylor College o...

The apparent lower risk of cancer due to gene therapy of other blood disorders is an important piece of good news that comes out of this study. "If we could find a way to eliminate the excess cells, and the ability of gamma C to insert into...

Long-life genes - A new way to combat cancer…

...he brain. In the study, the team mutated a tumor suppressor gene called gld-1 in the worms, causing cells in the animals' gonads to divide rapidly and form germ-line tumors. These tumor cells, when left undisturbed, break out of the gonad and fill the body, killing the worm at around 9 days old age. They t...

Test Helps Identify Patients with Breast Cancer

...o act as an oncogene // , and the other as a tumor suppressor - helps identify patients with breast cancer who will likely benefit from chemotherapy and those who won’t, according to researchers. The test, known as OncoPlan?, is already commercially available, and studies have shown that it can predict the agg...

Why Don’t All Moles Progress to Melanoma

Soengas says the results of the study will be important in helping scientists understand all the different mechanisms melanocytes use to protect themselves against oncogenes. But she cautions that there are no immedi...

'Muscle' Protein Drives Prostate Cancer

...nd, but also showed 10 times the amount of a tumor suppressor called thioredoxin-interacting protein (TXNIP). Prostate cancer, which affects one in nine American men over the course of their lives, is mainly diagnosed by needle biopsy of the prostate gland after a blood test shows an increased level of prosta...

A Novel Technique That Detects "Cancer Genes" From The Breath Of Smokers

Regulatory Mechanism for Tumor Suppressor Protein Identified

...er-active, might interfere with p53's normal tumor suppressor function and perhaps cause cancer. If that's the case, then we could develop drugs to inhibit the enzyme that would have the effect of freeing p53 to do its job of suppressing cancer. Unusually high levels of the newly identified enzyme might also be...

Profiling of Cancer Genes May Lead to Earlier Detection Human Cancers

...s that inhibit cancer development, so-called tumor suppressor genes, is often lost in tumor cells. This can occur through a mutation in the gene’s DNA sequence or through deletion of the gene. Loss of tumor suppression function also can occur in a process called methylation, where a chemical called a methyl gro...

Culprit Gene Behind Childhood Kidney Cancer Discovered

...esearchers have finally zeroed in on the new tumor suppressor gene, which is mutated in Wilms tumor, and the culprit behind the most frequently occurring kidney cancer// in children. Miguel Rivera and team from Massachusetts General Hospital said that almost 30 percent of Wilms tumor is due to mutations takin...

Dual Gene Therapy Suppresses Lung Cancer in Preclinical Test
