Extended Data Fig. 4. AgRP neuron ablation causes no difference in obesity development by NachBac.
a, Representative pictures showing immunostraining for AgRP in PVH (top panels) and Arc (bottom panels) in adult AgRPDTR/+ mice treated with either saline (left panels) or DTX (right panels) at day 3, repeated in 3 mice. b, NPY-GFP transgene was bred into AgRPDTR/+ mice, and DTX treatment led to almost complete ablation of NPY neurons in the Arc (arrows), repeated in one additional mouse. c-d, Expression of NachBac in the Arc of Vgat-Cre mice with AgRP neuron lesion caused reduced locomotion shown in representative traces (c) and comparison in locomotion between groups (d, n=5 each/groups, t=9.366, df=8, **p<0.0001, 2-sided Student’s t test). e, i.c.v. leptin infusion was confirmed by induction of p-STAT3 shown by immunostaining (bottom panels), compared to control PBS infusion (top panels), repeated in 3 mice. 3V: the third ventricle. Scale bar in b: 400 μM and arrows in panel b pointing to residual NPY neurons. Data presented as mean+/−sem.
