New signaling role for key protein may contribute to wound healing, tumor growth

The current study results revolve around proteinases, enzymes that break down proteins as part of cellular life. Matrix metalloproteinases or MMPs specifically target the extracellular matrix, the non-cell, structural framework within tissues. Beyond that role, the new study found that one member of this family, MMP-2, has another signaling role related to the human immune system. It may shift a set of cells to become part of immune response that accelerates healing in some cases, but may worsen inflammatory disease in others. …

Agent prevents prostate cancer growth, spread in animal studies — ScienceDaily

Published online Dec. 5 in PLOS ONE, the scientists say the agent, YK-4-279, is the first drug targeted at the chromosomal translocations found in about half of prostate cancer cells. These translocations occur when two normal genes break off from a chromosome and fuse together in a new location. …

Protein that controls the ‘guardian of the genome’ identified

The researchers study the development of T cells and B cells, which are lymphocytes (or immune cells) that play a central role in protecting our body against infections by viruses, bacteria and other microbial agents. “As these lymphocytes develop, they must learn how to recognize different pathogens in the body,” says Dr. M�r�y, Director of the Hematopoiesis and Cancer research unit at the IRCM. “Part of this process involves the breaking and rearranging of the genes responsible for producing the lymphocyte receptors that recognize these pathogens…

Approved breast cancer drug offers hope for the treatment of blood disorders

“Our study demonstrates that targeting estrogen signaling with a clinically approved drug, at doses with an acceptable toxicity profile in humans, provides a novel potential therapeutic strategy for a set of neoplasms currently without a definitive cure,” said senior study author Sim�n M�ndez-Ferrer of the National Center for Cardiovascular Research (CNIC) in Madrid, Spain. Myeloproliferative neoplasms cause large numbers of abnormal white blood cells to be produced and enter the bloodstream, potentially causing life-threatening symptoms. These diseases can lead to cancer and arise from blood cells called hematopoietic stem/progenitor cells (HSPCs), which give rise to all of the other blood cells. …

Smoking and higher mortality in men

Smoking is a risk factor for various diseases, not only lung cancer. Epidemiological data show that male smokers have a greater risk of developing cancer outside the respiratory tract than female smokers. In the present study, which is the result of an international collaboration, the researchers discovered an association between smoking and genetic damage among men that might explain this sex difference. ‘We have previously in 2014 demonstrated an association between loss of the Y chromosome in blood and greater risk for cancer…

Technology breakthrough reveals cellular transcription process

The technology is known as the “FISH investigation protocol” (Fluorescent in situ hybridization) — it optimises current flow cytometry processes, resulting in a greater visibility of the transcription of RNA, a key step in the transmission of cellular information. …
