MiR-301 is highly expressed, while PTEN is poorly expressed in ESCC tissues and cells. a Expression of miR-301 and mRNA expression of PTEN in the ESCC tissue detected using RT-qPCR; b protein expression of PTEN in the ESCC tissue detected using Western blot analysis; c protein bands of PTEN in the ESCC tissue in Western blot analysis; d expression of miR-301 and mRNA expression of PTEN in ESCC cell line detected using RT-qPCR; e protein expression of PTEN in ESCC cell line detected using Western blot analysis; f protein bands of PTEN in Western blot analysis. *P < 0.05 versus HEEC. Data were expressed as mean ± standard deviation, and the t test was performed for comparisons between two groups
