Recombinant nucleosomes with modified histones H3K9Ac (cat# 16-0314), H3K9Bu (cat# 16-0371), and H3K18Bu (cat# 16-0373) were purchased from EpiCypher, Inc., and analyzed by Western blotting with the corresponding antibodies.
Cellular protein (25-50 μg) was fractionated using a
subcellular protein fractionation kit (Thermo Fisher Scientific, cat# 78,840) according to the manufacturer's protocols. The cellular fractions were separated on a 4%–12% gradient SDS-PAGE (
Criterion gels, Bio-Rad) and transferred to nitrocellulose membranes. The antibodies used included
anti-H3K9Bu (Abcam, cat# ab241248),
anti-H3K18Bu (PTM Bio, cat# PTM-331),
anti-H3K9-crotonyl (RevMab, cat# 31-1225,099),
anti-H3K27-b-hydroxybutyryl (Abcam, cat# ab241463),
anti-H3K9-b-hydroxybutyryl (Thermo Fisher Scientific, PIPA5112503), anti-ACADS (Origene, cat# TA321036),
anti-ACAA2 (Origene, cat# TA506126), anti-ACC1/2 (Cell Signaling Technology, cat# 36,765),
anti-FASN (Abcam, cat# ab22759),
anti-H3 (Active Motif, cat# 61,476),
anti-H3K9Ac (Active Motif, cat# 39,917),
anti-AKT1 (Millipore 07-416), anti-voltage-dependent anion-selective channel 1 (
VDAC1, Genscript, cat# A01419),
anti-RNA pol II (Active Motif, cat# 102,660), and
anti-turboGFP (Origene, cat# TA150041). Western blotting signals were detected by an
Odyssey imaging system (LI-COR) and quantitated using ImageJ.
