MALAT1 and lung adenocarcinoma: In this study, thirty-nine cases of lung adenocarcinoma tumor tissues and normal tissues from 22 males and 17 females, aged 45–78 years, were collected and the two-year survival of patients with low expression of MALAT1 was significantly higher than that of MALAT1 high expression in lung adenocarcinoma patients (Long rank = 4.773, p = 0.0289) [77].
