Using similar bioinformatic techniques, several studies have suggested that functional FOXO6-eRNA can regulate FOXO6 expression to influence EGFR and SOX2 expression and function in lung cancer progression (167); furthermore, the aberrant expression of LINC00987/A2M axis was closely associated with immune cell infiltration in lung adenocarcinoma (168). Here, A2M is linked to lung adenocarcinoma.
