Protein arginine methyltransferase 5 (PRMT5) promotes survival of lymphoma cells via activation of WNT/B-catenin and AKT/GSK3B proliferative signaling
منشور في 2019"…We show that PRMT5 stimulates WNT/B-CATENIN signaling through direct epigenetic silencing of pathway antagonists, AXIN2 and WIF1, and indirect activation of AKT/GSK3 signaling.PRMT5 inhibition with either shRNA-mediated knockdown or a specific small molecule PRMT5 inhibitor, CMP-5, not only leads to derepression of WNT antagonists and decreased levels of active phospho-AKT (Thr-450 and Ser-473) and inactive phospho- GSK3B (Ser-9) but also results in decreased transcription of WNT/B-CATENIN target genes, CYCLIN D1, c-MYC, and SURVIVIN, and enhanced lymphoma cell death. …"

Wind energy potential along the onshore and offshore Qatar
منشور في 2020"…The present study aims at investigating the wind energy potential at select coastal locations of Qatar using ERA5 winds. ERA5 is the updated reanalysis product of the European Centre for Medium-range Weather Forecasts (ECMWF), in which the scatterometer and in situ wind data are assimilated to improve the accuracy of predictions, thus the long-term and short-term variabilities are reasonably well captured. …"
