Sexually dimorphic hepatic genes associated with NAFLD
Gene | Function (s) | Model (s) Used | Female | Male | Effect (s) |
---|---|---|---|---|---|
JNK | Transcription factor; regulate fatty acid oxidation; improve insulin sensitivity | SHROB Rats | ↑↑ | ↑ | Less severe steatosis in females |
AMPK | Transcription factor; regulate fatty acid oxidation; improve insulin sensitivity | SHROB Rats | ↑↑ | ↑ | Less severe steatosis in females |
CD36 | Receptor; promotes fatty acid uptake into muscle and adipose tissues; fatty acid transport, β-oxidation | SHROB Rats; FXR-deficient mice; C57BL6/J HFD Mice | ↑↑ | ↑ | Less severe steatosis in females |
PPARγ | Transcription factor; activates SREBP-1c, a master transcription factor that promotes de novo lipid synthesis (DNL) | SHROB Rats | ↑ | ↑↑ | More severe steatosis and inflammation in males |
PNPLA3 | Enzyme; involved in the accumulation of lipid droplets; esterification | SHROB Rats; C57BL6/J HFD Mice | ↑ | ↑↑ | More severe steatosis and inflammation in males |
AQP7 | The main channel in facilitating the release of lipolytic glycerol from adipocytes | C57BL/6 HFD mice, streptozotocin-induced DM rats | ↑↑ | ↑ | Increase plasma glycerol levels in both sexes |
AQP9 | The principal facilitative pathway in liver uptake of glycerol | C57BL/6 HFD mice, streptozotocin-induced DM rats | ↓↓ (Expression and glycerol permeability) | ↓ | Less severe steatosis and hyperglycemia in females |
SHROB: obese spontaneously hypertensive; ↑ increased; ↑↑ highly increased; ↓ decreased; ↓↓ highly decreased
