p53 Protein News and Research

RSS

The TP53 is a gene that instructs the cell to produce tumor protein (p53) ; a vital transcription factor and tumor suppressor. P53 is known as the “guardian of the genome” as it helps in regulating the cell cycle and acts as a tumor suppressor.

Unlocking intrinsically disordered proteins: an interview with Peter Wright

I'm a professor in the Department of Integrative Structural and Computational Biology at The Scripps Research Institute. I have been performing NMR research on proteins for nearly 40 years.

Kumamoto University researchers identify protein that limits severity of Alport syndrome

Researchers from Kumamoto University, Japan have identified a protein that limits the severity of Alport syndrome, a type of genetic kidney disease. The finding can provide clues that point toward new therapeutic approaches for Alport syndrome.

Study paves way for development of novel cancer therapeutics

A team of scientists, comprising researchers from the Institute of Molecular and Cell Biology, a research institute under the Agency for Science, Technology and Research, Singapore, and the VIB Laboratory of Molecular Cancer Biology, has revealed the mechanism by which tumor cells elevate levels of MDM4, a protein that is highly expressed in cancer cells but not in normal adult tissues.

Leading cancer researchers address eight 'big questions'

Leading cancer researchers address eight of the "big questions" facing the field as part of the inaugural issue of Trends in Cancer, published by Cell Press.

Study reveals new epigenetic mechanism underlying progression of cancer tumors

Aggressive cancer growth and alterations in gene activity without changes in DNA sequence (epigenetics) are associated with mutant p53 proteins, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Researchers uncover new mechanism that p53 protein uses to trigger cell death

Researchers have identified a new mechanism that the tumor suppressor protein p53 uses to trigger cell death via apoptosis and have shown how the process could be harnessed to kill cancer cells. St. Jude Children's Research Hospital scientists led the study, which appears today in the scientific journal Molecular Cell.

Removing accumulated mutant p53 protein regresses tumors, increases cancer survival

Removing accumulated mutant p53 protein from a cancer model showed that tumors regress significantly and survival increases. This finding, by an international team of cancer researchers led by Ute Moll, MD, Professor of Pathology at Stony Brook University School of Medicine, is reported in a paper published advanced online May 25 in Nature.

UC Davis researchers uncover complex relationship between p53 and Rbm38 proteins

Scientists have long known the p53 protein suppresses tumors. However, a recent animal study by UC Davis researchers has uncovered a complicated relationship between p53 and another protein, Rbm38, highlighting how the body calibrates protein levels. Too much Rbm38 reduces p53 levels, increasing the risk of cancer.

Study sheds new light on well-known mechanism required for immune response

A new study published in the scientific journal Proceedings of the National Academy of Sciences of the United States of America sheds new light on a well-known mechanism required for the immune response. Researchers at the IRCM, led by Tarik Möröy, PhD, identified a protein that controls the activity of the p53 tumour suppressor protein known as the "guardian of the genome".

Researchers discover new function of body's most important tumor-suppressing protein

Researchers at Cold Spring Harbor Laboratory (CSHL) have discovered a new function of the body's most important tumor-suppressing protein. Called p53, this protein has been called "the guardian of the genome."

Study shows inactivation of p53 protein promotes cancer progression

Researchers at the Bellvitge Biomedical Research Institute (IDIBELL) and the University of Barcelona have discovered the interaction between HERC2 proteins with another protein called p53 that is inactivated in more than half of human tumors.

Chemoprevention and colon cancer: an interview with Dr. John Letterio, Case Western Reserve University School of Medicine

The basic idea of cancer chemoprevention is to arrest or reverse the progression of premalignant cells towards full malignancy, using physiological mechanisms that do not kill healthy cells.

St. Jude analysis reveals how protein p53 triggers cancer cells to commit suicide

St. Jude Children's Research Hospital scientists have mapped the structural details of how p53 attaches to its regulatory protein, called BCL-xL, in the cell.

UAMS receives $1.8M grant to lead new treatments for herpes viruses and cancers

A surprise discovery that could lead to new treatments for herpes viruses that infect more than 90 percent of the world's adult population has led to a $1.8 million grant to the University of Arkansas for Medical Sciences (UAMS) from the National Cancer Institute (NCI) at the National Institutes of Health (NIH).

Alteration in tumor suppressor gene TP53 plays key role early in development of bone cancer

The St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project found mutations in the tumor suppressor gene TP53 in 90 percent of osteosarcomas, suggesting the alteration plays a key role early in development of the bone cancer.

Researchers discover genetic function that helps "tumor suppressor" genes to prevent cancer

Researchers at Oregon State University have discovered a genetic function that helps one of the most important "tumor suppressor" genes to do its job and prevent cancer.

Studies aim to address urgent need to identify possible new methods for mesothelioma treatment

Mesothelioma is a very aggressive cancer associated with asbestos exposure, which is usually diagnosed in an advanced stage. So far no therapeutic strategy has proven effective against this deadly cancer and the prognosis remains very poor with only few exceptions.

Findings establish gene as critical regulator of lung cancer tumor growth

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have shown that a well-known cancer-causing gene implicated in a number of malignancies plays a far more critical role in non-small cell lung cancer, the most common form of the disease, than previously thought.

p53 and cancer research: an interview with Professor Sir David Lane, Scientific Director of the Ludwig Institute for Cancer Research

P53 is a tumor suppressor gene. The gene encodes for a protein that monitors the state of the cell. If something goes wrong, it stops the cell from dividing or causes the cell to commit suicide. I call it the “guardian of the genome” as it is the molecule that seems to keep cells normal. It is one of our big defenses against cancer.
