Abstract
ObjectiveTo explore the autophagy effect of ghrelin on the ovarian cancer cell line SK-OV-3. And the lncRNA which regulate the ghrelin effect SK-OV-3 autophagy was showed.Methodsthe expression of ghrelin in the ovarian cancer tissues was analyzed according GEPIA database and HPA database. The CCK-8 was used to detect the the optimal concentration of ghrelin effect on the SK-OV-3. The influence on the SK-OV-3 cell autophagy by ghrelin was showed by detecting the expression of Beclin-1, LC3Ⅰand LC3Ⅱusing western blot. Linc00598 selected as the effecting the SK-OV-3 cells autophagy by ghrelin using RNA-Seq. And the Linc00598 which was silenced or overexressed promote the SK-OV-3 cells autophagy treated by ghrelin though western blot.ResultsGhrelin was expressed low in the ovarian cancer tissues. Ghrelin concentratio of 600 ng/ml was the optimal concentration o and 24 h was the optimal time. Ghrelin can promote the SK-OV-3 cell autophagy. Ghrelin mainly through linc00598 to promote the SK-OV-3 cells autophagy. When the linc00598 silenced, ghrelin promote SK-OV-3 cells autophagy was inhibited. And When the linc00598 overexpressed, ghrelin promote SK-OV-3 cells autophagy was inhanced.ConclusionsGhrelin promote SK-OV-3 cells autophagy. Additionally, we proved that ghrelin regulated the progression of SK-OV-3 cells autophagy by linc00598/ Beclin1 axis.
