Figure Lengend Snippet: C16orf87 partially mediates HDAC1 and MIER1 protein interactions. ( A ) C16orf87 interacts with the HDAC and MIER proteins. Volcano plot of the IP-MS experiment showing identified proteins interacting with the Flag-C16orf87 protein in HeLa cells. An adjusted P -value cut-off of 0.05 and a log2 fold change cut-off of 2 were used. Data are shown from a biological triplicate experiment. ( B ) Lack of C16orf87 does not change HDAC and MIER protein accumulation. Soluble Panc-01 WT (WT) and Panc-01 KO (KO) whole-cell lysates were analyzed by WB with the indicated antibodies. ( C ) C16orf87 partially mediates HDAC1 and MIER1 interaction. Co-immunoprecipitation of Flag-HDAC1 from siRNA (siC16 and siScr) and pcDNA3-Flag-HDAC1-transfected HeLa cells. Isolated proteins were analyzed by WB with the indicated antibodies. An arrowhead indicates the migration of the MIER1 protein isoforms, whereas an asterisk indicates the migration of the C16orf87 isoforms. ( D ) HDAC1 interacts weakly with C16orf87 in vitro. GST (as a control) and GST-HDAC1 pull-down with bacterially purified 8 × His-tagged C16orf87(Wt, 5 × C > A, 1–130, and 5 × C > A/1–130) proteins. An asterisk indicates a degradation product/partially translated GST-HDAC1. Proteins were detected with the anti-His and anti-GST antibodies.
Article Snippet: Human pancreatic cancer cell lines Panc-01 (ATCC, CRL-1469) and MiaPaCa-2 (ATCC, CRL-1420), mouse skeletal muscle cell line C2C12 (ATCC, CRL-1772), and human cervical cancer cell line HeLa S3 (ATCC, CCL-2.2) were used in this study.
