But this, of course, leaves Aunt Sally in Sarasota, Fla., with fewer options to visit family during the holidays; it leaves millions of us with longer boarding and exiting delays on our planes — and, yes, it helps drive up fare prices, too.
Loss of separase blocked centriole disengagement during mitotic exit and delayed assembly of new centrioles during the following S phase; however, most engagements were eventually dissolved.
When the exit was delayed for ten minutes while the astronauts continued to check their equipment, a hush finally fell over the group.
Conversely, overexpression of CBF slows cell cycle exit and delays muscle differentiation.
In contrast, overexpression of mutant fl-hCdc14BSL did not impair dephosphorylation of Cdk1 on Y15, but mitotic phosphorylation of H3-pSer10 was extended over a longer period of time (3 h compared to parental cells) (Fig. 1C), indicating that either progression through mitosis or mitotic exit were delayed.
This phosphorylation sensitizes mitochondria for MOMP if mitotic exit is delayed.
Live-cell imaging analysis also indicated that mitotic exit was delayed in the absence of SIK3.
Here, we demonstrate that a phosphorylated form of the BH3-only protein Bid regulates apoptosis if mitotic exit is delayed.
Thus, we show that Bid phosphorylation primes cells to undergo mitochondrial apoptosis if mitotic exit is delayed.
Concomitantly, mitotic exit was delayed for at least 5 h, until the end of the time course, by treatment with TSA, whereas control or CHX-treated cells exited from mitosis 1 h after nocodazole release.
