Chromosome activation
WebX chromosome inactivation has been studied for over 50 years both because it is a physiologically important event and because it is an excellent model for studying epigenetic silencing of genes by long non-coding RNAs. In her first talk, Dr. Jeannie Lee gives an overview of the steps a cell must go through during X inactivation. WebThe inactive X chromosome is silenced by being packaged into a transcriptionally inactive structure called heterochromatin. As nearly all female mammals have two X …

WebApr 25, 2016 · Chromosome segregation and mitotic exit are initiated by the 1.2-MDa ubiquitin ligase APC/C (anaphase-promoting complex/cyclosome) and its coactivator CDC20 (cell division cycle 20). To avoid chromosome missegregation, APC/C CDC20 activation is tightly controlled. CDC20 only associates with APC/C in mitosis when APC/C has …

WebDefective chromosome segregation during mitosis has been shown to cause DNA damage that induces structural rearrangements of chromosomes (s-CIN). In contrast, whether DNA damage can disrupt mitotic processes to generate whole chromosomal instability (w-CIN) is unknown. Here, we show that activation of the DNA-damage response (DDR) during ...
