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 how cancer protein changes may accelerate tumorigenesis and metastasis

Understanding the genetic mutations and protein changes that take place in the progression of cancer is key to its treatment. Mutations in the gene TP53 and concomitant mutant p53 proteins in cancer cells have become notorious over the course of multiple studies of several different types of cancers.

New study expands the knowledge on tumor-suppressor role of HERC proteins

The RAF protein could be a therapeutical target to treat the tumor growth in regulated pathways by the p38 protein, according to a new study published in the journal Scientific Reports by a team of experts of the Faculty of Medicine and Health Sciences of the University of Barcelona and the Bellvitge Institute for Biomedical Research.

Scientists pinpoint protein that plays key role in lung cancer and melanoma progression

Scientists from Far Eastern Federal University, University of Geneva (Switzerland), Minjiang University, and Fuzhou University (China) pointed out WDR74 protein playing an important role in lung cancer and melanoma primary tumors/metastases progression.

Iron overload, variant gene and malaria resistance linked in African study

A new study shows that a rare genetic mutation giving rise to a variant of the TP53 gene called P47S causes several linked biological processes.

p53 may play a more important role in kidney cancer than previously thought

The p53 gene, which researchers had thought was less relevant in kidney cancer, may play an important role after all – a discovery that could lead to new treatments.

Jefferson researcher probes kidney cancer's genes for interactions with p53 pathway

p53 is the most famous cancer gene, not least because it's involved in causing over 50% of all cancers. When a cell loses its p53 gene -- when the gene becomes mutated -- it unleashes many processes that lead to the uncontrolled cell growth and refusal to die, which are hallmarks of cancer growth.

Researchers identify chemical compounds that increase stability of haploid cell

Since the emergence of molecular genetics more than fifty years ago, scientists have tried to isolate haploid mammalian cells, that is, cells with half the number of chromosomes contained in somatic cells. Haploid cells are a powerful genetic tool to analyze gene function.

New spectroscopic approach investigates difficult-to-observe protein structures

Combining research-oriented teaching and interdisciplinary collaboration pays off: Researchers at the University of Konstanz develop a novel spectroscopic approach to investigate hitherto difficult-to-observe protein structures.

Small molecule drug could be an effective strategy to treat glioblastoma

A team of researchers have published in the International Journal of Oncology that RITA, a drug able to reactivate the oncosuppressor function of p53, could be an effective strategy to treat glioblastoma.

Study finding promises new perspectives for treatment of Type 2 endometrial cancer

Brazilian scientists identify the predominant presence of a truncated variant of the p53 protein in amyloid aggregates in endometrial cancer cells. Such structures are related to the progression of this tumor.

Synthetic compound reverses mutant p53 aggregate accumulation, study shows

Cancer is a multidisciplinary disease, with different mutations leading to different prognoses and treatment necessities. Among the most important mutation targets in cancers, affecting more than 50% of all cancer cases, is TP53.

Mutant p53 protein 'tackles' DNA guardian to drive tumor development

Melbourne scientists have discovered how tumor development is driven by mutations in the most important gene in preventing cancer, p53.

Loss of tumor protein p53 helps cancer cells grow in hostile environment

Researchers have discovered a novel consequence of loss of the tumor protein p53 that promotes cancer development, according to new findings in eLife.

Normal skin is more resilient to cancer than previously thought

Normal skin contains a patchwork of mutated cells, yet very few go on to eventually form cancer and scientists have now uncovered the reason why. Researchers at the Wellcome Sanger Institute and MRC Cancer Unit, University of Cambridge genetically engineered mice to show that mutant cells in skin tissue compete with each other, with only the fittest surviving.

Not all P53 mutations cause skin cancer

Today, scientists have explained for the first time why not all UV-induced, P53 mutated skin cells develop into cancer.

Ablating the mutant p53 gene in mice with colorectal cancer inhibits tumor growth

By genetically manipulating and removing the most common mutant form of the p53 gene that promotes colorectal cancer in humans, an international team of scientists demonstrated that this therapy reduces tumor growth and tissue invasion.

Anti-cancer gene may switch side and promote cancer growth, shows study

It doesn't often happen that army generals switch sides in the middle of a war, but when cancer's attack is underway, it may even cause a gene that acts as the body's master defender to change allegiance.

Researchers identify key protein involved in irregular brain cell activity

In a new study in mice, researchers have identified a key protein involved in the irregular brain cell activity seen in autism spectrum disorders and epilepsy. The protein, p53, is well-known in cancer biology as a tumor suppressor.

Researchers develop novel approach to fighting ovarian cancer

Researchers have discovered a cellular pathway that selectively regulates a mutant protein linked to the growth of ovarian cancer.

Combination therapy effectively induces tumor cell death and reduces spread of breast cancer

Each day, normal human cell tissues express a protein known as p53 that wages war against potential malignancies. However, between 30 and 40 percent of human breast cancers express a defective (mutant) form of p53 that helps cancer cells proliferate and grow.
