Human gastrointestinal tumor cells express and secret miR-1290. a Expression levels of miR-1290 were analyzed in different gastrointestinal cancer cells by RT-qPCR, including HT-29, HCT116, P4, ASPC-1, BXPC-3, SW1990, SW480, SW620, SGC7901, and BGC823. miR-1290 expression in HCT116, HT29, P4, ASPC-1 and BXPC-3 were relatively high. b miR-1290 expression levels in cellular supernatant of HT-29 when cultured with different cell densities for 24 h, 48 h, and 72 h. c miR-1290 expression levels in cellular supernatant of HCT116 when cultured with different cell densities for 24 h, 48 h, and 72 h. d miR-1290 expression levels in cellular supernatant of ASPC-1 when cultured with different cell densities for 24 h, 48 h, and 72 h. e miR-1290 expression levels in cellular supernatant of BXPC-3 when cultured with different cell densities for 24 h, 48 h, and 72 h. f miR-1290 expression levels in cellular supernatant of SGC7901 when cultured with different cell densities for 24 h, 48 h, and 72 h. ** p < 0.01, *** p < 0.001
