Type of chronodisruption | Metabolic phenotype | Reference |
---|---|---|
In white adipocyte | ||
ClockΔ19/Δ19 mice | Obesity, hypercholesterolemia and hyperglycemia; Circadian rhythm of lipolytic activity were abolished | |
Clock-siRNA-infected 3T3-L1 cells | Promote adipogenesis differentiation and lipid synthesis | [50] |
Bmal1-siRNA-infected 3T3-L1 cells | Prevent adipogenesis and decrease expression of lipogenesis genes | [51] |
Bmal1 − / − mice | Decrease novo lipogenesis; Circadian rhythm of lipolytic activity were abolished; Reduced capacity of fat storage in adipose tissue and increased ectopic fat | |
Up-regulated expression of Rev-erbα in 3T3-L1 cells | Promote adipogenesis | [53] |
Rev-erbα-deficient mice | Deregulated lipid metabolism | [54] |
Cry − / − mice | Reduced fat accumulation | [56] |
Cry-shRNA-infected 3T3-L1 cells | Expression of adipogenic markers and lipid droplet formation were inhibited | [57] |
Per3 − / − mice | Increased adipogenesis | [58] |
In brown adipocyte | ||
Clock mutant mice | Increased lipid accumulation and loss of multilocular appearance in brown adipocytes | [70] |
Brown adipocyte Bmal1 KO mice | Disrupted fatty acid utilization in brown adipocyte and obesity | [71] |
Bmal1 − / − mice | Increased lipid accumulation in brown adipocytes and dysregulated adaptive thermogenesis; Increased brown adipogenesis and clod tolerance | |
Rev-erbα − / − mice | Impaired brown adipogenesis; Disordered rhythms of body temperature and brown adipocyte activity | |
Rorα-deficient staggerer mice | Enhanced thermogenesis in brown adipocyte | [76] |
Per2-mutant mice | Impaired adaptive thermogenesis | [77] |
