Notch1 haploinsufficiency in mice accelerates adipogenesis

Notch signaling has been recognized recently as a key regulator of metabolism. Here, we determined the role of Notch1 in adipogenesis in wild-type (WT) and Notch1 hetero-mutant (N1+/-) mice provided with 12-week normal or high-fat diet. Haploinsufficiency of Notch1 was associated with adipose tissue accumulation despite similar food intake. White adipose tissue (WAT) of N1+/- showed accumulation of adipogenic cells (CD34+CD68+ cells), crown-like...
