Estrogen Regulation Of Mir-181a Stability In Neurons, Chun Kim
Master's Theses
Estrogens are an important class of steroid hormones involved in many cellular signaling processes. Levels of estrogens fluctuate across the lifespan suggesting that they target intracellular mediators, such as microRNAs, to fine-tune homeostatic cellular processes. Previous work in our lab demonstrated that 17β-estradiol (E2), the predominant circulating estrogen, stabilized miR-181a in a neuronal cell line derived from rat hypothalamus. These results lead to the hypothesis that E2 regulated miR-181a stability by altering the pool of endogenous RNA and by recruiting PNRC2 away from the miRNA degradation machinery. By utilizing miRNA degradation assays and immunostaining techniques, it was determined that the …
