... H3K27me3. However, we still do not fully understand what defines Polycomb targets, how their expression state is switched from epigenetically ON to OFF and how silencing is subsequently maintained through many cell divisions. An excellent system in which to dissect the sequence of events underlying...

... instances STIM2) that serves as the endoplasmic reticulum Ca 2+ sensor, and Orai (Orai1, Orai2 and Orai3) which function as pore-forming subunits of the store-operated channel. It has been known for some time that store-operated Ca 2+ entry is shut down during cell division. Recent work has revealed complex...

... (email nbhalla@ucsc.edu ). Research on reproductive aging focuses on the germline, the cells that give rise to the next generation. GSCs (germline stem cells) can self-renew or differentiate to produce cells undergoing meiosis, the specialized cell division that generates gametes, such as sperm...

...Katja Graumann; John Runions; David E. Evans Controlled movement of the nucleus is important in a wide variety of plant cellular events. Positioning involving intact nuclei occurs in cell division, development, tip growing systems such as the root hair and in response to stimuli, including light...

...Mary Kate Bonner; Ahna R. Skop Cell division is the most fundamental process in the development of all living organisms. The generation of cell diversity throughout development, the multiplication of cells during wound repair and the maintenance of stem cells in several tissues and organs all rely...
