LINC-PINT and lung adenocarcinoma: Next, to test whether the observed effects of PINT overexpression are specific to HCT116 cells, we generated a stably PINT-overexpressing A549 lung adenocarcinoma cell line (see Additional file 1: Figure S6D), and subjected the cells to similar analyses, determining their proliferation rate, cell cycle profile, and apoptosis levels.
