1. In the rat, acetyl-CoA carboxylase (ACC), a rate-limiting enzyme in fatty acid metabolism, exists as at least two different isozymes (M(r) 265,000 and 280,000) that display distinct tissue-specific distribution and regulation. 2. Based on the study of human tissue and human-derived breast cancer

The identification of an interaction between BRCA1 and acetyl-CoA carboxylase alpha (ACCalpha), a key enzyme in lipid synthesis, led us to investigate the role of ACCalpha in breast cancer development, where it might contribute to the energy-sensing mechanisms of malignant transformation. In order

A key fatty acid synthesis enzyme, acetyl-CoA carboxylase alpha (ACC-alpha), has been shown to be highly expressed in human breast cancer and other tumor types and also to specifically interact with the protein coded by one of two major breast cancer susceptibility genes BRCA1. We used a

Both increased de novo fatty acid synthesis and higher neutral lipid accumulation are a common phenotype observed in aggressive breast cancer cells, making lipid metabolism a promising target for breast cancer prevention. In the present studies, we demonstrate a novel effect of the active metabolite

We recently showed that the anaplerotic enzyme pyruvate carboxylase (PC) is up-regulated in human breast cancer tissue and its expression is correlated with the late stages of breast cancer and tumor size [Phannasil et al., PloS One 10, e0129848, 2015]. In the current study we showed that PC enzyme

Expression of the HER2 oncogene is increased in approximately 30% of human breast carcinomas and is closely correlated with the expression of fatty acid synthase (FASN). In the present study, we determined the mechanism by which FASN and acetyl-CoA carboxylase alpha (ACCalpha) could be induced by

BACKGROUND Overcoming systemic dormancy and initiating secondary tumor grow under unique microenvironmental conditions is a major rate-limiting step in metastatic progression. Disseminated tumor cells encounter major changes in nutrient supplies and oxidative stresses compared to the primary tumor

Cellular proliferation depends on refilling the tricarboxylic acid (TCA) cycle to support biomass production (anaplerosis). The two major anaplerotic pathways in cells are pyruvate conversion to oxaloacetate via pyruvate carboxylase (PC) and glutamine conversion to α-ketoglutarate. Cancers often

Recent studies have demonstrated that aldo-keto reductase family 1 B10 (AKR1B10), a novel protein overexpressed in human hepatocellular carcinoma and non-small cell lung carcinoma, may facilitate cancer cell growth by detoxifying intracellular reactive carbonyls. This study presents a novel function

Aim: Methylcrotonoyl-CoA carboxylase 2 (MCCC2), a subunit of 3-Methylcrotonyl-CoA carboxylase (MCC), is reported to be involved in tumor formation and development. However, the role of MCCC2 in breast cancer is unknown. Materials & methods: MCCC2 expression was examined in 138

Breast tumor recurrence and metastasis represent the main causes of cancer-related death in women, and treatments are still lacking. Here, we define the lipogenic enzyme acetyl-CoA carboxylase (ACC) 1 as a key player in breast cancer metastasis. ACC1 phosphorylation was increased in invading cells

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

Activation of de novo fatty acid synthesis is a characteristic feature of cancer cells. We have recently described an interaction between acetyl-CoA carboxylase alpha (ACCalpha), a key enzyme in fatty acid synthesis, and BRCA1, which indicates a possible connection between lipid synthesis and

Maintaining reductive-oxidative (redox) balance is an essential feature in breast cancer cell survival, with cellular metabolism playing an integral role in maintaining redox balance through its supply of reduced NADPH. In the present studies, the effect of 1,25-dihydroxyvitamin D (1,25(OH)2D) on

Rapid metabolism differentiates cancer cells from normal cells and relies on anaplerotic pathways. However, the mechanisms of anaplerosis-associated enzymes are rarely understood. The lack of potent and selective antimetabolism drugs restrains further clinical investigations. A small molecule ZY-444
