Abstract:
Objective:To investigate the effects of long-chain non-coding RNA ASB16 antisense RNA1 (ASB16-AS1) on the proliferation, migration and invasion of esophageal cancer cells by targeting microRNA (miR )-1258.Methods:Forty pairs of esophageal cancer tissues and matched adjacent tissues (distance of tumor margin>3 cm) resected in Xinxiang Central Hospital from May 2016 to July 2017 were collected. Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expressions of ASB16-AS1 and miR-1258 in esophageal cancer tissues and adjacent tissues. The small interfering RNA negative control (si-NC), ASB16-AS1 small interfering RNA (si-ASB16-AS1), miR-negative control mimics (miR-NC), miR-1258 mimics (miR-1258), si-ASB16-AS1 and anti-miR-NC, si-ASB16-AS1 and anti-miR-1258, si-ASB16-AS1 and anti-miR-1258 were transfected into Eca109 cells, respectively. Methyl thiazolyl tetrazolium (MTT) was utilized to detect the cell viability. Transwell assays were applied to detect cell migration and invasion. Double luciferase reporting experiment and qRT-PCR were used to confirm the relationship between ASB16-AS1 and miR-1258.Results:The expression levels of ASB16-AS1 and miR-1258 in esophageal cancer tissues were 2.95±0.27 and 0.62±0.06, respectively. Compared with 1.00±0.06 and 1.00±0.07 in adjacent tissues, the difference was statistically significant ( P<0.05). The cell viability of the si-NC group at 48 h and 72 h were 0.81±0.07 and 1.15±0.11, while those of si-ASB16-AS1 group were 0.46±0.04 and 0.62±0.06 ( P<0.05). The numbers of cell migration and invasion in the si-NC group were 86.32±8.24 and 71.29±7.15, respectively, while those of si-ASB16-AS1 group were 43.22±4.31 and 32.36±3.58, respectively, the differences were statistically significant ( P<0.05). The cell viability of the miR-NC group at 48 h and 72 h were 0.84±0.08, 1.18±0.12, while those of miR-1258 group were 0.55±0.05, 0.71±0.07 ( P<0.05). The migration and invasion numbers of the miR-NC group were (83.15±8.31) and (75.33±7.51), while those of miR-1258 group were (49.58±4.23) and (38.42±3.84), respectively, the differences were statistically significant ( P<0.05). The cell viability of the si-ASB16-AS1+ anti-miR-NC group at 48 h and 72 h were 0.45±0.04, 0.61±0.06, while those of si-ASB16-AS1+ anti-miR-1258 group were 0.72±0.07, 0.98±0.08; The migration and invasion numbers of cells in the si-ASB16-AS1+ anti-miR-NC group were 44.36±4.41 and 31.69±3.85, respectively, while those of si-ASB16-AS1+ anti-miR-1258 group were 72.65±7.27 and 61.22±6.14, respectively, and the differences were statistically significant ( P<0.05). ASB16-AS1 targeted negative regulation of miR-1258 expression. Conclusions:ASB16-AS1 upregulates in esophageal cancer. ASB16-AS1 promotes the proliferation, migration and invasion of esophageal cancer cells by targeting miR-1258.
