A nuclear-localized red fluorescence knock-in reporter allele for mouse pancreatic beta-cells

In this study, we generated a novel nuclear-localized red fluorescence knock-in reporter allele (Ins2.Apple) for mouse pancreatic beta-cells. Beta-cells were isolated by FACS from 60-day-old mice, segregated by sex, and RNA-sequencing was performed to assess sex-specific differences in beta-cell gene expression profiles. We also isolated beta-cells (by FACS) from MIP-GFP mice at 60 days of age. RNA-sequencing was performed, and was compared to that of Ins2.Apple beta cells, to assess gene expression changes brought on by the presence of the MIP-GFP transgene.
