Pyruvate carboxylase-mediated anaplerosis is a well-known regulator of gluconeogenesis. In this issue of Cell Metabolism, Cappel et al. (2019) show that pyruvate carboxylase action has far-reaching roles in metabolic homeostasis as it integrates glucose metabolism with tricarboxylic acid cycle flux, ureagenesis, redox potential, and defense against oxidative stress.

In our previous research, we found that not only participates in the detoxification metabolism of neonicotinoid insecticides in cotton aphid but also affects their growth and development. However, how does transgenic cotton expressing ds affect the growth and development of cotton aphid? In this study, we combined transcriptome and metabolome to analyze how to inhibit the growth and development of cotton aphid treated with transgenic cotton expressing ds (TG cotton). The results suggested that a total of 509 differentially expressed genes (DEGs) were identified based on the DESeq method, and a total of 431 differential metabolites (DAMs) were discovered using UPLC-MS in the metabolic analysis.

Nonalcoholic fatty liver disease (NAFLD) is one of the main causes of chronic liver disorders following liver transplantation. The prorenin receptor (PRR) plays a role in glucose and lipid metabolism, and the hepatic dysregulation of PRR is associated with the upregulation of several molecular pathways, such as the mammalian target of rapamycin (mTOR) and Peroxisome proliferator-activated receptor (PPAR) that promotes hepatic lipogenesis and leads to lipid accumulation in hepatocytes by upregulation of lipogenic genes. PRR inhibition leads to a reduction in the hepatic expression of sortilin-1 and low-density lipoprotein receptor (LDLR) levels and down-regulation of pyruvate dehydrogenase (PDH) and acetyl-CoA carboxylase (ACC) and reduces fatty acids synthesis in hepatocytes.

This study aims to investigate the potential causal link between mitochondrial function and breast cancer using the Mendelian randomization (MR) analysis. The data used for this study were obtained from genomewide association studies (GWAS) databases on mitochondrial biological function and breast cancer. Mitochondrial function was considered the exposure variable, breast cancer the outcome variable, and specific single nucleotide polymorphisms (SNPs) were selected as instrumental variables (IVs).

Pyruvate carboxylase (PC) catalyzes the carboxylation of pyruvate to oxaloacetate which serves as an important anaplerotic reaction to replenish citric acid cycle intermediates. In most organisms, the PC-catalyzed reaction is allosterically activated by acetyl-coenzyme A. It has previously been reported that vertebrate PC can catalyze the hydrolysis of acetyl-CoA, offering a potential means for the enzyme to attenuate its allosteric activation.
