( B ) The nucleic acid–protein complexes from ChIRP were fractionated on SDS-PAGE and subjected to mass spectrometry to identify proteins interacting with DRAIR probes. STRING analysis of indicated DRAIR -interacting proteins identified by ChIRP mass spectrometry . Colors represent GO biological functions shown in . ( C ) Immunoblotting of proteins from RNA pulldown assays using DRAIR and DRAIR antisense (DRAIR-AS) probes with G9a antibody. ( D ) qPCR analysis of RNA recovered after RNA IP with indicated antibodies. ( E – M ) ChIP-qPCR analysis of DNA recovered from ChIP assays using lysates from THP1 cells overexpressing DRAIR and empty vector pcDNA3.1 (EV) with antibodies against H3K9me2 ( E – H ), G9a ( I – L ), and H3K27me3 ( M ) using indicated gene promoter primers. ( N and O ) Immunoblotting of THP1 nuclear extracts with indicated antibodies ( N ) and quantification of G9a in nuclear extracts ( O ). THP1 cells were treated with NG (5.5 mM glucose) and HG (25 mM glucose) for 72 hours. Palmitic acid (PA, 200 μM) was also added in the final 24 hours to NG- (PA) and HG-treated (HP) cells. * P < 0.05; ** P < 0.01; *** P < 0.001 ( n = 3) as determined by unpaired t test ( E – L ) and 2-way ANOVA with Sidak’s ( M ), and 1-way ANOVA with Dunnett’s ( O ) multiple-comparison testing.
