In a Honduran population, the odds of having nonsyndromic cleft lip/palate (NSCLP) among carriers of the ACSS2 variant was 4.0 with a carrier frequency of 7.1% in unrelated affected and 1.9% in unrelated unaffected individuals. In a Colombian population, the odds of having NSCLP among carriers of the ACSS2 variant was 2.6 with a carrier frequency of 10.0% in unrelated affected and 4.1% in unrelated unaffected individuals.
In the nucleus, ACSS2 binds to transcription factor EB (zeige TFEB Antikörper) and translocates to lysosomal and autophagy gene promoter regions, where ACSS2 incorporates acetate generated from histone acetylation turnover to locally produce acetyl-CoA (zeige LPCAT2 Antikörper) for histone H3 (zeige HIST3H3 Antikörper) acetylation in these regions and promote lysosomal biogenesis, autophagy, cell survival, and brain tumorigenesis.
ACSS2 is essential for glucose-independent acetate-mediated cell survival and tumor growth.
Loss of ACSS2 expression is associated with with gastric cancer.
Study revealed that the activity of acetyl-CoA synthetase 2 (zeige ACSS1 Antikörper) (ACSS2) contributes to cancer cell growth under low-oxygen and lipid-depleted conditions.
Observations suggest that ACSS2 is expressed to a significant extent in particular tumor types, including triple-negative breast cancers.
Study shows that ACSS2 is upregulated in the human orthotopic tumor and primary human tumors, as well as a murine glioma model; the tumors do not oxidize [U-(13)C]glutamine (zeige GFPT1 Antikörper). In vivo oxidation of [1,2-(13)C]acetate was validated in brain tumor patients and was correlated with expression of acetyl-CoA synthetase enzyme 2, ACSS2.
During hypoxia, ACSS2 modulates interactions (zeige LPCAT2 Antikörper)of the acetylase/coactivator CBP with the stress-responsive transcription fa (zeige CREBBP Antikörper)ctor, HIF-2. These int (zeige CREBBP Antikörper)eractions include acetylation of HIF-2 by CBP as well as stable HIF-2/CBP comple (zeige EPO Antikörper)x formation, both of which are required for maximal HIF-2 signaling. Thus, ACSS2 links changes in metabolism that occur during stress with activation of a selective nuclear signaling pathway.
Ritonavir (at 100 mg once daily and 100 mg twice daily significantly down-regulated acyl-CoA synthetase short-chain family member 2 in 20 healthy individuals.
Because the activity of a bacterial ortholog of AceCS2 (zeige ACSS1 Antikörper), called ACS (zeige PLA2G15 Antikörper), is controlled via deacetylation by a bacterial sirtuin (zeige SIRT1 Antikörper) protein, our observation highlights the conservation of a metabolic regulatory pathway from bacteria to humans
results reveal a connection between cellular metabolism, gene regulation, and neural plasticity and establish a link between acetyl-CoA (zeige LPCAT1 Antikörper) generation 'on-site' at chromatin for histone acetylation and the transcription of key neuronal genes.
Study reports evidence that the nucleocytosolic ACSS2 enzyme is of critical importance for mammalian cells to utilize acetate as a source of acetyl-CoA (zeige LPCAT1 Antikörper), and that mice lacking this enzyme exhibit a substantial reduction in tumor burden in two genetic models of liver cancer.
Study shows that ACSS2 is upregulated in the human orthotopic tumor and primary human tumors, as well as a murine glioma model; the tumors do not oxidize [U-(13)C]glutamine (zeige GFPT1 Antikörper). In vivo oxidation of [1,2-(13)C]acetate was validated in brain tumor patients and was correlated with expression of acetyl-CoA synthetase (zeige Acsl1 Antikörper) enzyme 2, ACSS2.
Acss2 generates a specific pool of acetyl CoA (zeige LPCAT1 Antikörper) during hypoxia that modulates interactions of the acetylase/coactivator Cbp (zeige CREBBP Antikörper) (also known as Crebbp (zeige CREBBP Antikörper)) with the stress-responsive transcription factor, Hif-2. Because erythropoietin (zeige EPO Antikörper) is a Hif-2 target gene, red blood cell production in mice is also regulated by Acss2. Recovery from anemia is accelerated by administering acetate, although this requires the presence of Acss2.
Acetyl CoA synthetase-1 (AceCS1) is mainly expressed in oligodendrocytes in the rat brain. It is located both in cytosol and nucleus of mammalian cells.
Expression of cytosolic acetyl-CoA synthetase gene in mice is developmentally regulated
ACSS2 might play a buffering role in tumor acetyl-CoA (zeige LPCAT1 Antikörper)/acetate metabolism
This gene encodes a cytosolic enzyme that catalyzes the activation of acetate for use in lipid synthesis and energy generation. The protein acts as a monomer and produces acetyl-CoA from acetate in a reaction that requires ATP. Expression of this gene is regulated by sterol regulatory element-binding proteins, transcription factors that activate genes required for the synthesis of cholesterol and unsaturated fatty acids. Alternative splicing results in multiple transcript variants.
