Type:
ACLY links energy metabolism provided by catabolic pathways to biosynthesis. ACLY, which has been found to be overexpressed in many cancers, converts citrate into acetyl-CoA and OAA.ATP citrate lyase exhibited upregulation in various tumours.
General Tumour Biomarker
•ACLY is a key enzyme in cancer metabolism.
•ACLY is involved in glucose and lipid metabolism.
•Many ACLY inhibitors were developed as anti-cancer agents.

ACLY is a key enzyme in cellular metabolism that converts citrate into acetyl‐CoA and oxaloacetate. Acetyl‐CoA is a substrate for lipid synthesis and protein acetylation, processes that are often upregulated in cancer cells to support rapid growth and proliferation.

ACLY is found overexpressed in many aggressive cancers. ACLY abundantly consumes citrate from nutrient catabolism (especially glucose and glutamine) to support protein acetylation and intense nucleotide and lipid synthesis. The significant decrease in cytosolic citrate appears to play a central role in cancer metabolism by enhancing the Warburg effect and activating the PI3K / AKT axis promoting ACLY activity in a feedback loop. Thus, the inhibition of factors regulating its expression (such as SREBP1) and its activation (such as AKT) could have an anti-proliferative effect.

Elevated ACLY expression has been observed in a number of cancers. In many studies, high levels of ACLY have been associated with more aggressive disease and poorer prognoses.

1586- Citrate,    Extracellular Citrate Is a Trojan Horse for Cancer Cells
- in-vitro, Liver, HepG2
Dose?, At low concentration, citrate increased both histone H4 acetylation and lipid deposition; at high concentration, citrate inhibited both

ACLY↓, Considering the strong demand for acetyl-CoA but not for OAA in tumor cells, the exogenous citrate would behave like a trojan horse that carries OAA inside the cells and reduces ACLY expression and cellular metabolism.
selectivity↑, in non-tumor cells, changes of acetylated histone level do not correspond to a change of ACLY expression, as instead shown by HepG2 cells.
*ACLY∅, In contrast, ACLY expression in IHH (normal)cells was not modified after citrate exposure, suggesting that, in this case, ACLY expression was not regulated by histone H4 acetylation
Glycolysis↓, strong inhibition of glycolysis, which leads to a decrease in NADH necessary for OAA reduction
NADH↓,
OAA↑, exogenous citrate would behave like a trojan horse that releases OAA in the cells, where it could exert its therapeutic effect also on hepatoma cells.
other↑, most important discovery is undoubtedly the demonstration that high concentrations of citrate decrease the availability of acetyl-CoA, a key molecule both in the metabolism of sugars and lipids
