Figure Legend Snippet: a, Top, schematic of MMEJ reporter containing 5′-streptavidin-biotin linkages. Middle, internal termini of left and right MMEJ reporter DNA constructs. Bottom, schematic of MMEJ reporter assay. b−f, Bar plots showing relative GFP frequencies following cotransfection of left and right MMEJ reporter DNA constructs, with immunoblots showing abundance of protein shown in c and e−g. b, GFP+ frequencies are shown relative to nontargeting siRNA (siControl = 1) in wildtype HEK293T cells; n = 3; P = 0.01. c, GFP+ frequencies relative to POLλ+/+ 293T cells (POLλ+/+ = 1). n = 3, P = 0.01. d, Same as in b in POLλ−/− 293T cells. n = 3, P = 0.03. e, GFP+ frequencies relative to nontargeting siRNA (siControl = 1). n = 3, P = 0.04. f, GFP+ frequencies relative to nontargeting siRNA (siControl = 1) in XRCC4−/− 293T cells. Data represent means. n = 2, P = 0.04. g, MMEJ GFP reporter assay. Schematic of GFP reporter assay (top). Bar plot of percentage of GFP cells following transient expression of I-SceI and cotransfection of either Polλ siRNA or Control siRNA. n = 2, P = 0.04. h, Bar plots showing percentage of colonies relative to control after siRNA transfection in DLD1 BRCA2−/− or DLD1 Parental cells (top), in MDA-MB-436 BRCA1 mut or MDA-MB-231 cells (bottom). Percentage of colonies are normalized to nontargeting siRNA (siControl = 100). n = 1. Colony images are on the right. In b and c−g, GFP+ frequencies are normalized to transfection efficiency. Data represent means. ‘n’ denotes number of independent experiments with triplicates for each condition, ± s.e.m. *P < 0.05, **P < 0.01, ***P < 0.001. Statistical significance was measured from two-sample t-test and P values are indicated.
Techniques Used: Construct, Reporter Assay, Cotransfection, Western Blot, Expressing, Control, Transfection
Figure Legend Snippet: a. RT qPCR analysis of Polθ expression. mRNA levels were corrected with internal control for Actin in siRNA-treated cells used in Fig. 3b, ,dd as well as normalized to non-targeting siRNA (siControl = 1). Data represent mean. n = 1 experiment with triplicate for each condition ±SEM. b. gRNA sequence used to generate POLL−/− HEK293T cells via CRISPR-Cas9 engineering. Schematic representation of three isoforms of human Polλ with protein domains as well as location of gRNA sequence (red) is indicated. The genome sequence flanking the gRNA sequence (red) is shown in gray. POLL −/− clone # T2 was generated by CRISPR-Cas9 engineering and carries 7 bp deletion in both alleles. Sequence of the region harboring the 7 bp deletion is indicated in blue. c. Bar plot showing relative GFP following overexpression of indicated plasmids and co- transfection of left and right MMEJ reporter DNA constructs in HEK293T cells. GFP+ frequencies are normalized to transfection efficiency. Data represent mean. n = 1 experiment with triplicates for each condition, +/− s.e.m. Bottom panel: Immunoblot showing abundance of protein. d. gRNA sequence used to generate LIG4 −/− HEK293T cells (top) and XRCC4 −/− HEK293T cells (bottom) via CRISPR-Cas9 engineering. Schematic representation of human Lig4 (top) and Xrcc4 (bottom) with protein domains as well as location of gRNA sequence is indicated (red). e. Same as in Fig. 3f in XRCC4−/− HCT116 cells. Data represent mean. n = 1 experiment with triplicate for each condition, +/− s.e.m. Bottom panel: Immunoblot showing abundance of protein. f. Western blot of Polλ (top) and Gapdh (bottom) following transfection of either Polλ siRNA or siControl in DLD1 BRCA2+/+ (left) and DLD1 BRCA2 −/− cells (right).
