Article Title: Exploration of cardiometabolic and developmental significance of angiotensinogen expression by cells expressing the leptin receptor or agouti-related peptide

Figure Lengend Snippet: Localization of angiotensinogen (Agt) within the arcuate nucleus of the hypothalamus (ARC) and confirmation of cell-specific deletion of Agt in AgtLepr-KO and AgtAgrp-KO mice [mice exhibiting selective deletion of the Agt gene in cells that express either leptin receptor (Lepr) or agouti-related peptide (Agrp), respectively]. A: colocalization of Agt mRNA with mRNA for glial fibrillary acidic protein (Gfap), Lepr, proopiomelanocortin (Pomc), insulin II (Ins2), or Agrp in the ARC from a wild-type C57BL/6J mouse using in situ hybridization/RNAscope. DAPI, 4′,6-diamidino-2-phenylindole nuclear stain; ME, median eminence; 3V, third ventricle. B: loss of colocalization of Agt mRNA with Lepr in AgtLepr-KO mice. Black arrows identify a Lepr-positive (panel at left) but Agt-negative cell, whereas white arrows identify an Agt-positive, Gfap-positive neighboring cell. C: loss of colocalization of Agt mRNA with Agrp in AgtAgrp-KO mice. The black arrow identifies an Agrp-/Lepr-positive + Agt-negative cell, whereas the white arrow identifies an Agt-positive + Agrp-/Lepr-negative neighboring cell.
