RESUMEN
Objective The aim of this study was to explore the expression,prognosis and related function of Linc00152 in breast cancer.Methods Thirty-three cases of breast specimens were selected for RNA-Sequencing.The expression of Linc00152 was detected by qPCR in 50 pairs of breast cancer tissues and adjacent tissues.Combined with GEO and TCGA databases,the correla-tion between Linc00152 expression and the degree of malignancy and the prognosis of patients was analyzed.Cell proliferation,apopto-sis and cell migration were detected in breast cancer MDA-MB-231 cell line,gastric cancer SGC-7901 cell line and renal cell carcinoma 786-O cell line.Results Linc00152 was highly expressed in breast cancer(P<0.001),and was higher in HER2 posi-tive and triple negative breast cancer(P<0.001).In patients with high expression of Linc00152,the event-free survival and the me-tastasis-free survival were very poor(P<0.001,P<0.01).After knockdown Linc00152,the cell proliferation,migration and inva-sion were decreased and the apoptosis was increased(P<0.05).Conclusion Linc00152 has a role of promoting cancer in malignant tumors and may be a potential therapeutic target.
