Fig. 6. FSH receptor knock-out in the pituitary induces hepatic steatosis in females.

Fig. 6

a Illustration depicting the strategy to specifically disrupt FSH receptor expression in the pituitary via stereotaxic delivery of an adeno-associated virus (AAV) encoding Cas9 and a guide RNA targeting Fshr into the pituitary. b Percentage of unmodified and modified alleles and c distribution of identified alleles around the predicted cleavage site determined by CRISPResso2 of the pituitary DNA from an AAV5-saCas9-Fshr injected mouse. d Representative images (scale bars = 50 μm) and e quantification of liver oil red O staining from AAV-Cas9 (with (n = 3 mice) or without (n = 5 mice) guide RNA against follicle-stimulating hormone receptor; Fshr) pituitary-injected mice. f Liver oil red O staining quantification in AAV-Cas9 (with guide RNA against follicle-stimulating hormone receptor; Fshr) pituitary-injected adrenalectomized or sham-operated female mice. g Model of gonadotrope actions on the gonads and the pituitary (filled blue arrow illustrates gonadotrope actions on the gonads; dashed blue arrows indicate indirect gonadotrope effects on pancreas and bone via sex steroids released by the gonads; filled red arrow indicates corticotrope action on the adrenal cortex (via paracrine FSH intra-pituitary action); dashed red arrow indicates the effect of elevated corticosterone levels on the liver). Error bars represent the standard error of the mean. ** = P < 0.01. For statistical details, including individual P-values, see Supplementary Data 1. Source data are provided as a Source Data file.
