WebJun 15, 2011 · Europe PMC is an archive of life sciences journal literature. WebIn contrast to the decrease in PGC-1α, estrogen increased protein levels of nuclear respiratory factor 1, a known PGC target and mediator of mitochondrial biogenesis. The latter effect of estrogen was independent of PI3K, suggesting a separate mechanism consistent with increased expression of PGC-1β and PRC.

WebCircular RNAs (circRNAs) are a recently discovered class of RNAs derived from protein-coding genes that have important biological and pathological roles. They are formed through backsplicing during co-transcriptional alternative splicing; however, the unified mechanism that accounts for backsplicing decisions remains unclear. Factors that regulate the … WebNUCLEAR BODY MAINTENANCE The steady-state appearance of nuclear bodies is maintained by the continuous flow of mole-cules into and out of the body (Fig. 1D). The size, and possibly shape, of nuclear bodies is likely determined by the balance of on-rate relative to the off-rate of its components. An increase in on-rate or a drop in the off-rate
