miR-122 Regulates LHR Expression in Rat Granulosa Cells by Targeting Insig1 mRNA.

abstract：:During lung development there is tension between positive and negative regulators of fibroblast-epithelial communication controlling type II cell differentiation. A clinical consequence of imbalance of this tension is the increased risk for respiratory distress syndrome in male infants. We hypothesized that chronic in...
