$a Immunoblotting of Drosha, DGCR8, and β-actin in the LM2-DRR (expressing the pLCN DSB Repair Reporter) cell line transduced with DGCR8 shRNA. b Knockdown of DGCR8 decreased HR and NHEJ efficiency in LM2-DRR cells. Two days after co-transfection of I-SceI endonuclease and an exogenous donor for HR (pCAGGS DRR mCherry Donor EF1a BFP) into the DGCR8-knockdown LM2-DRR cells, the percentages of GFP-positive and mCherry-positive cells, gated on BFP-positive cells, were determined by flow cytometry. Repair by HR or NHEJ leads to mCherry or GFP expression. Data were normalized to the control cells. n = 3 biological replicates. c MYC-DGCR8-overexpressing LM2 cells were treated with IR (8 Gy) and cultured for 1 h, followed by pulldown with MYC beads and immunoblotting with the indicated antibodies. d Control and DGCR8-knockdown LM2 cells were treated with IR (8 Gy) and cultured for 1 h, followed by immunoprecipitation with an antibody against RNF168 or <t>RNF8</t> and immunoblotting with the indicated antibodies. e Chromatin was extracted from LM2 cells that were treated with IR (8 Gy) and cultured for 1 h.
