Figure Lengend Snippet: ACAA2/TRβ1 transcriptional assay. Inhibiting O-GlcNAc in transfected TH-treated CV-1 cells reduced ACAA2 activation of TRβ1 transcriptional activity. TRβ1 – thyroid receptor β1; ACAA2 – acetyl-coenzyme A acyltransferase; T3 – thyroid hormone; TG – thiamet G, OGA inhibitor; OSMI-1 – OGT inhibitor. Statistics – one-way ANOVA – correct for multiple comparison- test: Šidák post hoc analysis was performed (n = 4).

Figure Lengend Snippet: Assessment of specificity of the anti-H2BS112GlcNAc antibody. ( A ) Immunoreactivity of the anti-H2BS112GlcNAc antibody on H2BS112GlcNAc and corresponding unmodified H2B peptides (KHAVS 112 EGTK) immobilized on nitrocellulose. Peptides were preincubated without or with 2 ng/µL recombinant OGA prior to immunodetection. ( B ) Immunofluorescence peptide competition assay using H2BS112GlcNAc and unmodified H2B peptides; immunodetection using anti-H2BS112GlcNAc. Scale bar, 10 μm. ( C ) Immunoblot of ASC extracts preincubated with 0 or 2 ng/µL recombinant OGA for 30 min. ( D ) Expression of an EGFP-H2BS112A mutant, but not a control wild-type EGFP-H2B, in HeLa cells reduces H2BS112GlcNAc immunoreactivity ( left ) without affecting detection of total H2B ( middle ) or EGFP ( right ).

Article Snippet: Lysates were incubated for 30 min at room temperature with 2 ng/μL recombinant OGA (6779GH020, R&D Systems) and dissolved in 2× Laemmli buffer for SDS-PAGE and immunoblotting.
