Methylation- and homologous recombination deficiency-related mutant genes predict the prognosis of lung adenocarcinoma.

Background: Lung adenocarcinoma (LUAD) is a lung cancer subtype with poor prognosis. We investigated the prognostic value of methylation- and homologous recombination deficiency (HRD)-associated gene signatures in LUAD.

Methods: Data on RNA sequencing, somatic mutations, and methylation were obtained from TCGA database.

Overexpression of miR-758 inhibited proliferation, migration, invasion, and promoted apoptosis of non-small cell lung cancer cells by negatively regulating HMGB.

Non-small cell lung cancer (NSCLC) is one of the most fatal types of cancer with significant mortality and morbidity worldwide. MicroRNAs (miRs) have been confirmed to have positive functions in NSCLC. In the present study, we try to explore the role of miR-758 in proliferation, migration, invasion, and apoptosis of NSCLC cells by regulating high-mobility group box (HMGB) 3 (HMGB3.
