چکیده انگلیسی
xCT, the functional subunit of the system xcâ encoded by the Slc7a11 gene, plays an important role in maintaining intracellular glutathione (GSH) levels. In previous study, we have indicated that xCT deficiency induces OS and that OS triggers apoptosis through JNK pathway, however, this induction of apoptotic features did not fully explain the cell death induced by xCT deficiency. In the current study, we demonstrated that sut melanocytes of xCT deficiency showed activation of both ER stress and autophagy. And that the activation of autophagy by xCT deficiency was mediated by ER stress induced activation of p38 MAPK and NF-κB pathways and subsequently inhibited functions of Akt/mTOR/p70S6K survival pathways, ultimately led to autophagic cell death of sut melanocytes. Our novel results provided important insights into understanding the mechanism associated with xCT deficiency.
