Glucocorticoids and cyclic AMP selectively increase hepatic lipin-1 expression, and insulin acts antagonistically.

|
Glucocorticoids (GCs) increase hepatic phosphatidate phosphatase (PAP1) activity.
|

|
PAP1 catalyzes the conversion of phosphatidate to diacylglycerol, a key substrate for TAG and phospholipid biosynthesis.
|

|
PAP1 enzymes in liver include lipin-1A and -1B (alternatively spliced isoforms) and two distinct gene products, lipin-2 and lipin-3.

|
We determined the mechanisms by which the composite PAP1 activity is regulated using rat and mouse hepatocytes.
|

|
Levels of lipin-1A and -1B mRNA were increased by dexamethasone (dex; a synthetic GC), and this resulted in increased lipin-1 synthesis, protein levels, and PAP1 activity.
|
7 |

|
Lipin-2 and lipin-3 mRNA were not increased by dex/cAMP, indicating that increased PAP1 activity is attributable specifically to enhanced lipin-1 expression.
|

|
Selective lipin-1 expression explains the GC and cAMP effects on increased hepatic PAP1 activity, which occurs in hepatic steatosis during starvation, diabetes, stress, and ethanol consumption.

Growing evidence links the three mammalian lipin proteins, i.e., lipin-1, lipin-2 and lipin-3, to metabolic and cardiovascular diseases such as noninsulin-dependent diabetes mellitus and atherosclerosis.

Genetic variants within the human LPIN1 and LPIN2 genes are associated with metabolic syndromes.

The fatty liver dystrophy (fld) mice carrying mutations within the Lpin1 gene display life-long deficiency in adipogenesis, insulin resistance, neonatal hepatosteatosis and hypertriglyceridemia, as well as increased atherosclerosis susceptibility.
|

|
Cell culture studies show that hepatic lipin-1 expression is selectively stimulated by glucocorticoids and repressed by insulin, and its subcellular localization governs the assembly and secretion of very low density lipoproteins (VLDL).

Depletion of lipin-2 promotes the increased expression of the proinflammatory genes Il6, Ccl2, and Tnfα, which depends on the overstimulation of the JNK1/c-Jun pathway by saturated fatty acids.
