The identified DEGs such as retinoid X receptor alpha (<i>RXRA</i>)<i>,</i> cyclin-dependent kinase 2 (<i>CDK2</i>)<i>,</i> histone deacetylase 2 (<i>HDAC2</i>), and <i>KIT</i> might be the target genes of lung cancer by participating in different pathways such as ECM-receptor interaction.
Endogenous HDAC2 directly correlates with BAP1 across a panel of lung cancer cell lines, and is downregulated in mesothelioma cell lines with genetic BAP1 inactivation.
Taken together, we suggest that the aberrant regulation of HDAC2 and its epigenetic regulation of gene transcription in apoptosis and cell cycle components play an important role in the development of lung cancer.
