Preclinical, Journal: PI3K inhibitor reduces in vitro maturation and developmental competence of porcine oocytes. (Pubmed Central) - Jun 22, 2021 LY-294002 treatment decreased the developmental potential of blastocysts following parthenogenetic activation, increased the level of cell apoptosis and reduced the level of cell-cycle. This study revealed that inhibiting the PI3K signaling pathway could reduce in vitro maturation and developmental competence of porcine oocytes, probably by reducing cell cycle arrest and proliferation, promoting the oocyte apoptosis, and altering the expression of other maternal genes.

Preclinical, Journal: β-Estradiol Enhanced Secretion of Lipoprotein Lipase from Mouse Mammary Tumor FM3A Cells. (Pubmed Central) - Jun 22, 2021 In addition, the effect of E on LPL secretion was markedly suppressed by an inhibitor of mammalian target of rapamycin complex (mTORC) 1 and 2, KU0063794, but were not by a mTORC1 inhibitor, rapamycin. Furthermore, a small interfering RNA (siRNA)-mediated decrease in the expression of rapamycin-insensitive companion of mTOR (Rictor), a pivotal component of mTORC2, suppressed secretion of LPL by E. These results suggest that the stimulatory secretion of LPL by E from the tumor cells is closely associated with an activation of mTORC2 rather than mTORC1 possibly via the MAPK cascade.

Journal, IO biomarker: Bioactive compound from the Tibetan turnip (Brassica rapa L.) elicited anti-hypoxia effects in OGD/R-injured HT22 cells by activating the PI3K/AKT pathway. (Pubmed Central) - Jun 8, 2021 Western blot analysis results also implied that active-constituent pretreatment reversed the diminished expression of the PI3K/Akt/mTOR pathway mediated by oxygen glucose deprivation/reperfusion (OGD/R); further experimental evidence showed that the protective role was limited in the PI3K inhibitor (LY294002) treatment group. Our results demonstrated that the functional monomer of B. rapa L. exerted a neuroprotective effect against OGD/R-induced HT22 cell injury, and its potential mechanism provides a scientific basis for future clinical applications and its use as a functional food.
