Article Title: A genome-wide knock-out screen for actors of epigenetic silencing reveals new regulators of germline genes and 2-cell like cell state
doi: 10.1101/2021.05.03.442415
Figure Lengend Snippet: (A) RT-qPCR analysis of the expression of 2C-specific genes in Spop KO, Mcm3ap KO, Kdm5c KO, and Zbtb14 KO, compared to the parental DASH mES cells (n=3 clones per KO). (B) Western blot analysis of ZSCAN4 and MERVL-Gag for Spop KO, Mcm3ap KO, Kdm5c KO, Zbtb14 KO, and parental DASH mES cells cultured in Serum or 2i. (C) RT-qPCR analysis of the expression of 2C-specific genes for Spop KO, Mcm3ap KO, Kdm5c KO, and Zbtb14 KO, transfected with either an empty plasmid or their respective CDS, compared to the parental DASH mES cells (n=3, clones per KO). (D) Western blot analysis of V5, ZSCAN4, and MERVL-Gag in 4 candidates KO, transfected with an empty plasmid or their respective V5-tagged CDS. (E) Model for role of novel epigenetic factors ZBTB14, KDM5C, SPOP, MCM3AP, BEND3, and KMT2D in the regulation of germline genes, and 2 cell-like cell state.
Article Snippet: For rescue experiments, the coding sequence (CDS) of candidates was synthesized (for Bend3, Spop, and Zbtb14) (GenScript), amplified from cDNA ( Kdm5c ), or obtained from colleagues (for Mcm3ap , kindly shared by Prof. N. Sakaguchi, ).
