While it has been known for some time that malonyl-CoA does exist in heart tissue, and that it is a potent inhibitor of carnitine palmitoyltransferase 1 (CPT 1), it has only recently been demonstrated that an isoenzyme of ACC exists in the heart that is a potential source of malonyl-CoA.

Leptin increased fatty acid oxidation by stimulating the activity of carnitine palmitoyltransferase-1 (CPT-1) and inhibiting that of acetyl-CoA carboxylase (ACC), pace-setting enzymes for fatty acid oxidation and synthesis, respectively.

|
Leptin-induced ROS generation, CPT-1 activation, ACC inhibition, and MCP-1 overproduction were found to be completely prevented by either genistein, a tyrosine kinase inhibitor, H-89, a protein kinase A (PKA) inhibitor, or tetradecylglycidate, a CPT-1 inhibitor.

ACC stimulation by glutamate and magnesium was maximally demonstrable in the cytosolic fraction; it was markedly reduced by okadaic acid (OKA) in concentrations (<50 nmol/l) that inhibited protein phosphatase 2A (PP2A).
|

11423479
|
Furthermore, pretreatment of the cytosolic fraction with anti-PP2A serum attenuated the glutamate- and magnesium-mediated activation of ACC, thereby suggesting that ACC may be regulated by an OKA-sensitive PP2A-like enzyme.
|

|
Streptavidin-agarose chromatography studies have indicated that glutamate- and magnesium-mediated effects on ACC are attributable to activation of ACC's dephosphorylation; this suggests that the stimulatory effects of glutamate and magnesium on ACC might involve activation of an OKA-sensitive PP2A-like enzyme that dephosphorylates and activates ACC.

Together, our data provide evidence for a unique regulatory mechanism for the activation of ACC in the pancreatic beta-cell, leading to the generation of physiological signals that may be relevant for physiological insulin secretion.

AMP-activated protein kinase (AMPK) plays a major role in the regulation of cardiac fatty acid oxidation by inhibiting acetyl-CoA carboxylase (ACC) and reducing malonyl-CoA levels.

|
The present study demonstrates that metformin (0.5-2mM) also dose-dependently activates AMPK in insulin-producing MIN6 cells and in primary rat beta-cells, leading to increased phosphorylation of acetyl coA carboxylase (ACC).

|
Another mechanism involves the inhibition of acetyl-CoA carboxylase (ACC) synthesis of malonyl-CoA, due to AMP-activated protein kinase (AMPK) phosphorylation of ACC.

|
These changes were associated with reduced expression of lipogenic genes (SREBP1c, ACC1, SCD1, and mtGPAT) and increased expression of oxidative/thermogenic genes (CPT1 and UCP2).

|
The phosphorylation of AMPK-alpha and protein expression of GLUT4 were decreased, but the phosphorylation of ACC was unchanged in diabetic rat hearts.

|
Phosphorylation of AMPK and ACC in response to A-769662 is also abolished in isolated mouse skeletal muscle lacking LKB1, a major upstream kinase for AMPK in this tissue.
|
18 |
17855357
|
However, in HeLa cells, which lack LKB1 but express the alternate upstream kinase calmodulin-dependent protein kinase kinase-beta, phosphorylation of AMPK and ACC in response to A-769662 still occurs.

Breast cancer-associated mutations affecting the highly-conserved C-terminal BRCT domains of the tumor suppressor gene breast cancer susceptibility gene 1 (BRCA1) fully disrupt the ability of BRCA1 to interact with acetyl coenzyme A carboxylase alpha (ACCA), the rate-limiting enzyme catalyzing de novo fatty acid biogenesis.
|
20 |
17620310
|
Specifically, BRCA1 interacts solely with the phosphorylated (inactive) form of ACCA (P-ACCA), and the formation of the BRCA1/P-ACCA complex interferes with ACCA activity by preventing P-ACCA dephosphorylation.
|
21 |
17620310
|
Alternatively, new forthcoming ACCA inhibitors may be relevant in the management of BRCA1-dependent breast cancer susceptibility and development.

|
Despite a similar reduction in HbA(1c) and similar improvement in insulin sensitivity with nutritional therapy, there were no significant changes in muscle AMPK and ACC phosphorylation, or the expression of ADIPOR1, ADIPOR2, PPARGC1 and genes involved in mitochondrial function and fat oxidation.

Under both conditions, knockdown of CBR1 by specific siRNA increased ?-cell apoptosis, expression of lipogenic enzymes (such as ACC, FAS, and ABCA1), intracellular lipid accumulation, oxidative stress, ER stress, and nuclear SREBP1c, but decreased glucose-stimulated insulin secretion.

Our studies show that metformin treatment (1) significantly inhibited proliferation of diverse chemo-responsive and -resistant ovarian cancer cell lines (A2780, CP70, C200, OV202, OVCAR3, SKVO3ip, PE01 and PE04), (2) caused cell cycle arrest accompanied by decreased cyclin D1 and increased p21 protein expression, (3) activated AMPK in various ovarian cancer cell lines as evident from increased phosphorylation of AMPK? and its downstream substrate; acetyl co-carboxylase (ACC) and enhanced ?-oxidation of fatty acid and (4) attenuated mTOR-S6RP phosphorylation, inhibited protein translational and lipid biosynthetic pathways, thus implicating metformin as a growth inhibitor of ovarian cancer cells.

The saury oil diet also resulted in downregulated expression of the lipogenic genes (SREBP-1, SCD-1, FAS, and ACC) as well as upregulation of the fatty acid oxidative gene, CPT-1, and the energy expenditure-related genes (PGC1? and PGC1?) in white adipose tissue for the diet-induced obese C57BL/6J mice.
