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.

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.

p53 restoration of function drug candidate: an interview with Dr. Wayne Danter, MD, FRCPC President and CEO of Critical Outcome Technologies

COTI-2 is a computer-designed small molecule that was discovered by our artificial intelligence drug discovery platform called CHEMSAS.

Tumor suppressor p53 inactivation and restoration: an interview with Dr. Xin Lu, Ludwig Institute for Cancer Research

Before we talk about p53, it is important to understand why cancer cells are a problem for the body. Cancer cells multiply recklessly, refuse to die and blithely metastasize to set up shop in places where they don’t belong.

Study suggests possible way to halt cancer development in premalignant cells

Scientists have uncovered a survival mechanism that occurs in breast cells that have just turned premalignant-cells on the cusp between normalcy and cancers-which may lead to new methods of stopping tumors.

Inherited mutations in p53 gene put people at high risk of developing cancers

The understanding of how a powerful protein called p53 protects against cancer development has been upended by a discovery by Walter and Eliza Hall Institute researchers. More than half of human cancers carry defects in the gene for p53, and almost all other cancers, with a normal p53 gene, carry other defects that somehow impair the function of the p53 protein. Inherited mutations in the p53 gene put people at a very high risk of developing a range of cancers.

Mechanism of tumor suppressor p53 inactivation described

Cancer cells are a problem for the body because they multiply recklessly, refuse to die and blithely metastasize to set up shop in places where they don’t belong. One protein that keeps healthy cells from behaving this way is a tumor suppressor named p53. This protein stops potentially precancerous cells from dividing and induces suicide in those that are damaged beyond repair. Not surprisingly, p53’s critical function is disrupted in most cancers.

Researchers identify new mechanism in onset of motor neuron diseases

The British astrophysicist Stephen Hawking is likely to be the world's most famous person living with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. ALS is a progressive disease affecting motor neurons, nerve cells that control muscle function, and nearly always leads to death.

TP63 gene correlates significantly with worse prognosis of melanoma

Scientists at Queen Mary, University of London have identified a gene present in some melanoma which appears to make the tumour cells more resistant to treatment, according to research published today in the Journal of Experimental Medicine.

Scientists identify specific p53 pocket that can be targeted by cancer-fighting drugs

UC Irvine biologists, chemists and computer scientists have identified an elusive pocket on the surface of the p53 protein that can be targeted by cancer-fighting drugs. The finding heralds a new treatment approach, as mutant forms of this protein are implicated in nearly 40 percent of diagnosed cases of cancer, which kills more than half a million Americans each year.

p53 activation suppresses malic enzyme expression and leads to senescence in pre-cancerous cells

It is perhaps impossible to overstate the importance of the tumor suppressor gene p53. It is the single most frequently mutated gene in human tumors. p53 keeps pre-cancerous cells in check by causing cells, among other things, to become senescent - aging at the cellular level. Loss of p53 causes cells to ignore the cellular signals that would normally make mutant or damaged cells die or stop growing.

Study on effect of glucose on cancer growth in mice

An animal study conducted by researchers at Georgetown Lombardi Comprehensive Cancer Center raises questions about the consequences of diet - specifically glucose, the plant-based sugar that fuels cell life - on increased activity of an oncogene that drives tumor growth.

Researchers discover genetics secrets of ovarian cancer tumors

A new discovery that sheds light on the genetic make up of ovarian cancer cells could explain why some women survive longer than others with this deadly disease.
