Small heterodimer partner/neuronal PAS domain protein 2 axis regulates the oscillation of liver lipid metabolism.

ABSTRACT:

Unlabelled

In mammals, circadian rhythms are essential for coordinating the timing of various metabolic processes. The Clock gene regulates diurnal plasma triglyceride fluctuation through nuclear receptor small heterodimer partner (Shp; Nr0b2). Given that SHP is a critical regulator of metabolism in the liver, it is unknown whether SHP is necessary to coordinate metabolism and circadian rhythms. Shp(+/+) and Shp(-/-) mice on a C57BL/6 background (n = 3-5/group) were fed a standard chow diet and water ad libitum. Serum and livers were collected at zeitgeber time 2, 6, 10, 14, 18, and 22. In vivo and in vitro assays included RNA sequencing, quantitative polymerase chain reaction, very-low-density lipoprotein production, adenovirus overexpression and small interfering RNA knockdown, s
