Nogo-B receptor (NgBR) was identified as a specific receptor for binding Nogo-B
and is essential for the stability of Niemann-Pick type C2 protein (NPC2) and
NPC2-dependent cholesterol trafficking. Here, we report that NgBR expression
levels decrease in the fatty liver and that NgBR plays previously unrecognized
roles in regulating hepatic lipogenesis through NPC2-independent pathways. To
further elucidate the pathophysiological role of NgBR in mammals, we generated
NgBR liver-specific knockout mice and investigated the roles of NgBR in hepatic
lipid homeostasis. The results showed that NgBR knockout in mouse liver did not
decrease NPC2 levels or increase NPC2-dependent intracellular cholesterol levels.
However, NgBR deficiency still resulted in remarkable cellular lipid accumulation
that was associated with increased free fatty acids and triglycerides in
hepatocytes in vitro and in mouse livers in vivo. Mechanistically, NgBR
deficiency specifically promotes the nuclear translocation of the liver X
receptor alpha (LXR?) and increases the expression of LXR?-targeted lipogenic
genes. LXR? knockout attenuates the accumulation of free fatty acids and
triglycerides caused by NgBR deficiency. In addition, we elucidated the
mechanisms by which NgBR bridges the adenosine monophosphate-activated protein
kinase alpha signaling pathway with LXR? nuclear translocation and LXR?-mediated
lipogenesis. CONCLUSION: NgBR is a specific negative regulator for LXR?-dependent
hepatic lipogenesis. Loss of NgBR may be a potential trigger for inducing hepatic
steatosis. (Hepatology 2016;64:1559-1576).
