Asynchronous cell cycle phase key to critical stage of animal embryonic development Posted: 18 Apr 2016 10:06 AM PDT The synchronous mitosis of early embryonic development switches to a patterned form at the 11th cell division following removal of a cell cycle compensatory mechanism, new research shows. An asynchronous S-phase length is masked by a compensatory asynchronous G2-phase length up to the 11th mitosis, after which the transition to spatial patterning occurs. These findings help in understanding the link between mitotic timing and embryonic development.

Researchers find method that could resurrect an abandoned pancreatic cancer targeted drug Posted: 18 Apr 2016 09:27 AM PDT Pancreatic cancer is on track to become the second leading cause of cancer-related deaths by 2020. These statistics are due, in part, to pancreatic cancer's resistance to most targeted cancer therapies. Working with pancreatic cancer cells, researchers have now found a mechanism that could be responsible for the cancer's resistance to at least one targeted approach. If the results hold true in animal models and eventually clinical trials, the approach could help researchers develop more effective combination therapies and breathe new life into forgotten and failed cancer drugs.
