2019-10-1 · Once DNA damage is initiated, major transducers such as ATM and ATR cooperate to regulate this pathway. Upon activation, ATM/ATR activates the checkpoint kinases Chk1 and Chk2, and thus activates p53. The p53, in turn, induces the expressions of different ligands for NK cell-activating receptors . Our data demonstrate that RuSe was able to ...
Abstract. Selenium (Se) is a naturally occurring metalloid element which occurs nearly in all environments in the universe. The common sources of Se in earth crust occurs in association with sulfide minerals as metal selenide whereas, it is rarely seen in elemental form (Se 0).Furthermore, Se is considered a finite and non-renewable resource on earth, and has been found to be an essential ...
