    ATCC 32d cells
    Validation of a Btk site-specific gene editing approach (A) Schematic of Btk editing strategy. The top row shows the Btk gene with exons and introns. In the second row, zooming in on intron 1 and exon 2 of the Btk gene, shows the sites where sgRNAs targeting these regions will allow for Cas9 dsDNA breaks. In the third row, recombinant adeno-associated virus (rAAV) vectors containing a nearly full-length human BTK cDNA with 500-bp homology arms directly flanking the dsDNA break site to allow for homologous recombination at either the intron 1 or exon 2 sites. The BTK cDNA donor also contains a “micro” version of the terminal intron 18, Btk 3′ UTR, and WPRE element. The bottom row depicts the BTK minigene inserted into the endogenous murine Btk locus at the intron 1 or exon 2 sites. (B) Outline displaying <t>32D</t> and Lin- cell editing timeline. Cells are cultured in either R-10 or SFEM + cytokines for the times listed, then electroporated with Cas9 RNP followed directly by transduction with rAAV6 donor. One week post editing, genomic DNA and total protein lysates are harvested for analysis of allelic disruption, gene integration, and exogenous Btk protein expression. (C and G) Genomic DNA harvested from 32D and Lin- cells, respectively, was PCR amplified with primers flanking the Cas9/sgRNA cut sites and sent for Sanger sequencing analysis of Btk allelic disruption via synthego ICE analysis. The y axis represents the frequency of amplified DNA copies which contained insertions/deletions at the Btk dsDNA break site. n = 3. (D and H) Twenty-four hours post electroporation, 32D and Lin- cells, respectively, were analyzed for viable cell counts using hemacytometers and trypan blue exclusion to determine the acute toxic effects of editing reagents. The y axis represents the average percentage of live cells counted across two individual aliquots of a given sample. (E and I) Genomic DNA harvested from 32D and Lin- cells, respectively, underwent in/out ddPCR analysis using primers and probes that allow for specific quantification of BTK cDNA insertion at its endogenous locus to quantify Btk site-specific integration frequency. The y axis represents the frequency of site-specific Btk integration events normalized to a reference housekeeping gene. n = 3. (F and J) Western blot protein analysis of Btk expression from Btk −/− 32D cells and Btk/Tec −/− Lin- cells, respectively. Cells were lysed using RIPA lysis buffer followed by western blotting and chemiluminescent detection of Btk and Beta-Actin protein expression levels; 32D cells were transfected with equivalent Cas9-RNPs followed by transduction of rAAV6 at MOIs of either 1e5 or 5e5. To determine the role of rAAV6 transduction alone on exogenous Btk expression, Lin- cells either received Cas9-RNP or no electroporation, followed by transduction with rAAV6 at an MOI of 5e5. n = 3.

SLC5A5 gene expression levels were normalized to BETA-ACTIN expression in the same samples, and fold changes were adjusted relative to the expression levels in control samples. ( C , D ) The iodine concentration was assessed in cell lysates of A253 ( C ) and WR21 ( D ) cells 48 h after KI treatment at the indicated concentrations ( n = 4/5 per group). ( E ) Representative light microscopy images of murine WR21 and human A253 SGC cells 48 h after incubation with or without KI (100 μM; scale bar = 100 μm).

( G , H ) The absolute number of viable and control (co) A253 ( G ) and WR21 cells ( H ) after 48 h in culture, following the addition of KI (100 μM), was determined using the trypan blue exclusion assay ( n = 10 and 5/group for A253 cells and n = 4, 3/group for WR21 cells). * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 using a one-way ANOVA test (to determine the effects of two independent variables on a dependent variable) or Student’s t -test (to compare the performance of two groups under different conditions), with mean ± SD depicted.

    Validation of a Btk site-specific gene editing approach (A) Schematic of Btk editing strategy. The top row shows the Btk gene with exons and introns. In the second row, zooming in on intron 1 and exon 2 of the Btk gene, shows the sites where sgRNAs targeting these regions will allow for Cas9 dsDNA breaks. In the third row, recombinant adeno-associated virus (rAAV) vectors containing a nearly full-length human BTK cDNA with 500-bp homology arms directly flanking the dsDNA break site to allow for homologous recombination at either the intron 1 or exon 2 sites. The BTK cDNA donor also contains a “micro” version of the terminal intron 18, Btk 3′ UTR, and WPRE element. The bottom row depicts the BTK minigene inserted into the endogenous murine Btk locus at the intron 1 or exon 2 sites. (B) Outline displaying 32D and Lin- cell editing timeline. Cells are cultured in either R-10 or SFEM + cytokines for the times listed, then electroporated with Cas9 RNP followed directly by transduction with rAAV6 donor. One week post editing, genomic DNA and total protein lysates are harvested for analysis of allelic disruption, gene integration, and exogenous Btk protein expression. (C and G) Genomic DNA harvested from 32D and Lin- cells, respectively, was PCR amplified with primers flanking the Cas9/sgRNA cut sites and sent for Sanger sequencing analysis of Btk allelic disruption via synthego ICE analysis. The y axis represents the frequency of amplified DNA copies which contained insertions/deletions at the Btk dsDNA break site. n = 3. (D and H) Twenty-four hours post electroporation, 32D and Lin- cells, respectively, were analyzed for viable cell counts using hemacytometers and trypan blue exclusion to determine the acute toxic effects of editing reagents. The y axis represents the average percentage of live cells counted across two individual aliquots of a given sample. (E and I) Genomic DNA harvested from 32D and Lin- cells, respectively, underwent in/out ddPCR analysis using primers and probes that allow for specific quantification of BTK cDNA insertion at its endogenous locus to quantify Btk site-specific integration frequency. The y axis represents the frequency of site-specific Btk integration events normalized to a reference housekeeping gene. n = 3. (F and J) Western blot protein analysis of Btk expression from Btk −/− 32D cells and Btk/Tec −/− Lin- cells, respectively. Cells were lysed using RIPA lysis buffer followed by western blotting and chemiluminescent detection of Btk and Beta-Actin protein expression levels; 32D cells were transfected with equivalent Cas9-RNPs followed by transduction of rAAV6 at MOIs of either 1e5 or 5e5. To determine the role of rAAV6 transduction alone on exogenous Btk expression, Lin- cells either received Cas9-RNP or no electroporation, followed by transduction with rAAV6 at an MOI of 5e5. n = 3.
