After being blocked with TBS with Tween-20 (TBST) containing 5% (w/v) non-fat dried skim milk powder for 24 h at 4˚C, membranes were incubated with a CacyBP/SIP antibody (cat. no. 3354; 1:1,000) or a GAPDH antibody (cat. no. 3683; 1:1,000; both from Cell Signaling Technology, Inc.) overnight at 4˚C. p21 antibody (ab188224; 1:1,000), cyclin-dependent kinase (CDK) 2 antibody (ab32147; 1:1,000), CDK4 antibody (ab199728; 1:2,000), Cyclin D1 antibody (ab226977; 1:2,000), Cyclin E1 antibody (ab33911; 1:2,000), Bax antibody (ab32503; 1:2,000) and Bcl-2 antibody (ab692; 1:500) were purchased from Abcam.
