Regulated in Development and DNA Damage Responses 1 Prevents Dermal Adipocyte Differentiation and Is Required for Hair Cycle-Dependent Dermal Adipose Expansion.

ABSTRACT: Dermal white adipose tissue (dWAT) expansion is associated with important homeostatic and pathologic processes in skin. Even though mTOR/protein kinase B signaling is important for adipogenesis, the role of regulated development of DNA damage responses 1 (REDD1), a negative regulator of mTOR/protein kinase B, is poorly understood. Loss of REDD1 in mice resulted in reduction of body mass, total fat, size of gonadal white adipose tissue, and interscapular brown adipose tissue. Inguinal subcutaneous white adipose tissue and dWAT in REDD1 knockouts were expanded compared with wild type mice. Size and number of mature adipocytes in dWAT were also increased in adult REDD1 knockouts. This dWAT phenotype was established around postnatal day 18 and did not depend on the hair growth cycle.
