PGM5P4 and lung carcinoma: According to the results of the transwell assay, we found that the invasive activity of the lung cancer cells was increased by the down-regulation of PGM5P4-AS1 (the invasion cell number: 106.80±12.96, 107.73±15.50 vs. 73.00±8.59) and decreased by the up-regulation of PGM5P4-AS1 (the invasion cell number: 68.07±7.37 vs. 113.27±13.31;).
