Protein aggregation, generally associated with Alzheimer's and mad cow disease, turns out to play a significant role in cancer. In a paper published in Nature Chemical Biology, Frederic Rousseau and Joost Schymkowitz of VIB, K.U.Leuven and Vrije Universiteit Brussel describe that certain mutations of p53, an important tumor suppressor, cause the protein to misfold in a way that the proteins start to aggregate. This not only disrupts the protective function of normal p53, but of other related...

Metabolic function for tumor suppressor points to new cancer therapeutics The gene for the protein p53 is the most frequently mutated in human cancer. It encodes a tumor suppressor, and traditionally researchers have assumed that it acts primarily as a regulator of how genes are made into proteins. Now, researchers at the University of Pennsylvania School of Medicine show that the protein has at least one other biochemical activity: controlling the metabolism of the sugar glucose, one of...

Tumor suppressor p53 launches miR-200c to reverse epithelial-to-mesenchymal transition Like a bounty hunter returning escapees to custody, a cancer-fighting gene converts organ cells that change into highly mobile stem cells back to their original, stationary state, researchers report online at Nature Cell Biology. This newly discovered activity of the p53 gene offers a potential avenue of attack on breast cancer stem cells thought to play a central role in progression and spread of the...

Female quality control in oocytes Chemotherapeutic agents, used in cancer treatment, destroy not only cancer cells but also healthy cells, thus affecting germ cells as well. Consequently, after surviving cancer many female patients are confronted with the diagnosis: infertility. For a long time a relationship between infertility and chemotherapeutic agents has been assumed, but until now, the exact mechanism was not known. Scientists from the research group of Prof. Volker Dötsch...

One of the most important genes in the human genome is called p53 and its function is to suppress tumours, according to Roger Leng, a researcher in the Faculty of Medicine & Dentistry. Leng has discovered the mechanism by which p53 is inactivated in cancerous cells, allowing tumors to grow. "Successful completion of the proposed experiments could lead to novel anti-cancer therapies that could potentially improve the prognosis for cancer patients and reduce the public health burden from...

First clinical trial looks at RG7112 as a way to disable MDM2 in leukemia A pioneering clinical trial is testing the effectiveness in leukemia of a small molecule that shuts down MDM2, a protein that can disable the well-known tumor suppressor p53. Michael Andreeff, M.D., Ph.D., professor of Medicine and chief of Molecular Hematology and Therapy in the Department of Leukemia at The University of Texas MD Anderson Cancer Center, presented preliminary results of this ongoing Phase I study at...

(Ivanhoe Newswire)-- Although p53 is called the "guardian of the genome", having the job of preventing defective cells from dividing, some cancer cells have found a loop hole. "The critical importance of the protective function of p53 is underscored by the diversity of molecular strategies employed by cancer cells to subvert p53 activity, such as overexpression of antagonistic proteins like HDM2 and HDMX," Dr. Loren D. Walensky, senior study author of Harvard Medical School, was quoted as...

It is common for cancer cells to find some way to disarm p53, also known as "guardian of the genome" due to its action in preventing defective cells from dividing. "The critical importance of the protective function of p53 is underscored by the diversity of molecular strategies employed by cancer cells to subvert p53 activity, such as overexpression of antagonistic proteins like HDM2 and HDMX," explains senior study author Dr. Loren D. Walensky from Harvard Medical School. "Restoration of p53...

New research links three molecules to a critical tumor suppressor gene that is often turned off in multiple myeloma, a presently incurable cancer of the blood. The findings might offer a new strategy for treating this disease and other blood cancers, according to researchers at The Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC "“ James) who led the study. The silenced molecules are called miR-192,...

Sister gene of tumor-suppressor works by regulating the production of micro RNAs Long overshadowed by p53, its famous tumor-suppressing sibling, the p63 gene does the tougher, important job of stifling the spread of cancer to other organs, researchers at The University of Texas MD Anderson Cancer Center report in the Oct. 21 issue of Nature. Not only does a specific form of p63 protein block metastasis, but it does so by activating the enzyme Dicer, which plays a pivotal role in the creation...
