Article Title: Generation and characterization of CRISPR/Cas9-mediated MEN1 knockout BON1 cells: a human pancreatic neuroendocrine cell line
doi: 10.1038/s41598-020-71516-7
Figure Lengend Snippet: ( A ) The human MEN1 is located on chromosome 11q13, from base pair 64,803,514 to 64,811,294, and harbors ten exons. More than 1,000 inactivating and disease-associated mutations, detectable in all coding regions, have been reported. The sequence overviewing exon 2, without exon/intro boundaries, is shown. CRISPR target regions are marked as Men1.1, Men1.2 and Men1.3 with genomic location chr11(64,809,842), chr11(64,809,853) and chr11(64,809,732), respectively. ( B ) Cropped western blot image showing menin protein expression in MEN1-KO-BON1 and BON1 (duplicate experiments). ( C ) Representative (n = 3) cropped western blot images showing chromogranin A (CHGA), ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), neurotensin (NTS), neuroendocrine regulatory peptide (VGF), sphingosine-1-phosphate lyase 1 (SGPL1) and phosphoserine aminotransferase (PSAT1) protein expression in MEN1-KO-BON1 and BON1. The full-length blots are presented in the Supplementary Figure . The relative protein expression levels were quantified as mean for three repeated experiments.
