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.

Supercomputer simulations of p53 protein could boost future anti-cancer drug discovery

Even though it's almost impossible to see, computational biophysicist Rommie Amaro is using the Stampede supercomputer at the Texas Advanced Computing Center at The University of Texas at Austin to model the largest atomic level system of the tumor suppression protein p53 to date -- over 1.5 million atoms.

Breakthrough Award supports research on role of chronic stress in breast cancer development

Rutgers Cancer Institute of New Jersey resident research member Wenwei Hu, PhD, has received a $596,250 Breakthrough Award from the U.S. Department of Defense through its Breast Cancer Research Program to study the role of chronic stress in breast cancer development.

Columbia researchers find way to reawaken potent cancer-fighting molecule in tumor cells

A potent cancer-fighting molecule in our cells can be reawakened by reducing levels of a protein - called SET - that's often found in excess in cancer cells, a new study from Columbia University's Herbert Irving Comprehensive Cancer Center has found.

Studying mutant peptides may help detect weaknesses in tumor cells

Researchers from MIPT, the Institute of Biomedical Chemistry, the Institute for Energy Problems of Chemical Physics, and the Research Institute of Physico-Chemical Medicine have presented an algorithm to detect mutant proteins based on mass spectrometry data and the results of exome sequencing.

Researchers show how p53 protein can control gene expression at levels of transcription, mRNA translation

Proteins that bind DNA or RNA are usually put in different categories, but researchers at Umea University in Sweden and Inserm in France recently showed how the p53 protein has the capacity to bind both and how this controls gene expression on the levels of both transcription (RNA synthesis) and mRNA translation (protein synthesis).

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.
