Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have identified the mechanism by which protein Zds1 regulates a key function in mitosis, the process that occurs immediately before cell division. The result has been achieved in the online edition of the Journal of Cell Science and opens the door to developing targeted and direct therapies against cancer. http://phys.org/news256555210.html Biology Fri, 18 May 2012 10:20:19 EST news256555210 A research team has identified epigenetic signatures, markers on DNA that control transient changes in gene expression, within reprogrammed skin cells. These signatures can predict the expression of a wound-healing protein in reprogrammed skin cells or induced pluripotent stem cells (iPSCs), cells that take on embryonic stem cell properties. Understanding how the expression of the protein is controlled brings us one step closer to developing personalized tissue regeneration strategies using stem cells from a patient, instead of using human embryonic stem cells. The study was published in the Journal of Cell Science. http://phys.org/news250948569.html Biology Wed, 14 Mar 2012 12:56:36 EST news250948569 (PhysOrg.com) -- New research from the University of Melbourne shows how the malaria parasite (Plasmodium falciparum) changes into a banana shape before sexual reproduction, a finding that could provide targets for vaccine or drug development and may explain how the parasite evades the human immune system. http://phys.org/news248420538.html Biology Tue, 14 Feb 2012 05:42:46 EST news248420538 Scientists at the University of East Anglia have made an important breakthrough in the way anti-cancer drugs are tested. http://phys.org/news206273579.html Medicine & Health Thu, 14 Oct 2010 11:30:04 EST news206273579 Van Andel Research Institute (VARI) researchers have developed a new method to better study the cells that line and protect the prostate in relation to the development of cancer. Using the model, they found that normal cells and cancer cells depend on different factors to survive, which could aid in discovering how to target cancer cells without affecting normal cells when developing treatments. http://phys.org/news187538498.html Medicine & Health Thu, 11 Mar 2010 14:20:01 EST news187538498 (PhysOrg.com) -- Every day, about 10 billion cells in a human body commit suicide. Cells infected by virus, that are transformed or otherwise dysfunctional altruistically sacrifice themselves for the greater good. Now, new imaging experiments have revealed a previously unseen order to this process, showing closely related cells dying in synchrony as a wave of destruction sweeps across their mitochondria, snuffing out the main source of energy that keeps cells alive. http://phys.org/news186412550.html Biology Fri, 26 Feb 2010 13:16:07 EST news186412550 A protein found present in all cells in the body could help scientists better understand how we store fat. http://phys.org/news172403290.html Chemistry Thu, 17 Sep 2009 11:00:02 EST news172403290 A protein found in cells has been shown to play a pivotal role in determining whether a cell lives or dies. http://phys.org/news166719345.html Biology Mon, 13 Jul 2009 15:56:09 EST news166719345 Scientists at Albert Einstein College of Medicine of Yeshiva University have discovered how a gene crucial in triggering the spread of breast cancer is turned on and off. The findings could help predict whether breast tumors will metastasize and also reveal potential drug targets for preventing metastasis. The study will appear in the May 20th online edition of the Journal of Cell Science. http://phys.org/news161355941.html Medicine & Health Tue, 12 May 2009 14:06:16 EST news161355941
