Unravelling evolutionary strategies of yeast for improving galactose utilization through integrated systems level analysis.

abstract：:Although preterm delivery is a major global health issue, its causes and underlying mechanism remain elusive. Using mutant mice, mimicking aspects of human preterm birth, we show here that uterine decidual senescence early in pregnancy via heightened mammalian target of rapamycin complex 1 (mTORC1) signaling is a sign...
