Telomere shortening protects against cancer
As time goes by, the tips of your chromosomes–called telomeres–become shorter. This process has long been viewed as an unwanted side-effect of aging, but a recent study shows it is in fact good for you. “Telomeres protect the genetic material,” says Titia de Lange, Leon Hess Professor at Rockefeller. “The DNA in telomeres shortens when cells divide, eventually halting cell division…

Scientists detail how chromosomes reorganize after cell division
Researchers have discovered key mechanisms and structural details of a fundamental biological process–how a cell nucleus and its chromosomal material reorganizes itself after cell division. The new findings in chromosomes architecture and function may offer important insights into human health and disease. “During mitosis, as a cell divides into two daughter cells, virtually all the genes are temporarily turned off,…

Scientists find molecule crucial for cell movement
Cells require specific protein on their surface for cell movement in absence of which cells can’t move normally, UConn scientists report in Science Signaling. The latest study could give understanding into how cells move and fix wounds in ordinary tissue, it can also provide insights into how cancer spreads through the body. Cells are the body’s workers, and they usually…

New Protein Modifying Method Can Develop Precise Cancer Drugs
Background Protein research is one of the highly studied areas in the field of medical science. The ability of the proteins to develop far more effective drugs for cancer, diabetes, etc is utilized by the researchers. However, it is also important to note that while proteins show great potential in the development of pharmaceuticals, they also pose trickiest challenges. They…
