Fig. 6From: Metformin regulates expression of DNA methyltransferases through the miR-148/-152 family in non-small lung cancer cellsNegative effect of low miR-148b expression on overall survival of 42 NSCLC patients. A–C Expression levels of miR-148a in tumor tissues from 42 NSCLC patients were compared according to age (A), histology (B), or recurrence (C). D–F Relationships between overall survival and expressions of miR-148a (D), miR-148b (E), and miR-152 (F) in 42 NSCLC patients were analyzed using Kaplan–Meier survival estimates. P-value was calculated using the log-rank testBack to article page
