Allosteric regulation alters carrier domain translocation in pyruvate carboxylase

open access: yesNature Communications, 2018
Carrier domain enzymes accomplish catalysis by physically transporting intermediates long distances between remote active sites. Here the authors describe a wide range of catalytically productive translocation events during catalysis by pyruvate ...

Nonstructural 5A protein of hepatitis C virus interacts with pyruvate carboxylase and modulates viral propagation. [PDF]

open access: yesPLoS ONE, 2013
Hepatitis C virus (HCV) is highly dependent on cellular factors for its own propagation. By employing tandem affinity purification method, we identified pyruvate carboxylase (PC) as a cellular partner for NS5A protein. NS5A interacted with PC through the

The MDM2–p53–pyruvate carboxylase signalling axis couples mitochondrial metabolism to glucose-stimulated insulin secretion in pancreatic β-cells

open access: yesNature Communications, 2016
Mice lacking the tumour suppressor p53 are partially protected from developing diabetes. Here the authors show that p53 is upregulated in the pancreas of diabetic mice where it impairs β cell function by repressing expression of mitochondrial pyruvate ...

PC Splice-Site Variant c.1825+5G>A Caused Intron Retention in a Patient With Pyruvate Carboxylase Deficiency: A Case Report

open access: yesFrontiers in Pediatrics, 2022
BackgroundPyruvate carboxylase deficiency (PCD; MIM#266150) is a rare autosomal recessive disorder characterized by a wide range of clinical features, including delayed neurodevelopment, elevated pyruvate levels, lactic acidosis, elevated ketone levels ...

Kinetic modelling of β‐cell metabolism reveals control points in the insulin‐regulating pyruvate cycling pathways

open access: yesIET Systems Biology, 2023
Insulin, a key hormone in the regulation of glucose homoeostasis, is secreted by pancreatic β‐cells in response to elevated glucose levels. Insulin is released in a biphasic manner in response to glucose metabolism in β‐cells.

Impaired G2/M cell cycle arrest induces apoptosis in pyruvate carboxylase knockdown MDA-MB-231 cells

open access: yesBiochemistry and Biophysics Reports, 2021
Background: Previous studies showed that suppression of pyruvate carboxylase (PC) expression in highly invasive breast cancer cell line, MDA-MB-231 inhibits cell growth as a consequence of the impaired cellular biosynthesis. However, the precise cellular

Hypoxia-mediated repression of pyruvate carboxylase drives immunosuppression

open access: yesBreast Cancer Research
Background Metabolic plasticity mediates breast cancer survival, growth, and immune evasion during metastasis. However, how tumor cell metabolism is influenced by and feeds back to regulate breast cancer progression are not fully understood.

The citrate cleavage pathway and lipogenesis in rat adipose tissue: replenishment of oxaloacetate

open access: yesJournal of Lipid Research, 1967
Fatty acid synthesis via the citrate cleavage pathway requires the continual replenishment of oxaloacetate within the mitochondria, probably by carboxylation of pyruvate.Malic enzyme, although present in adipose tissue, is completely localized in the ...

Pyruvate carboxylase supports the pulmonary tropism of metastatic breast cancer

open access: yesBreast Cancer Research, 2018
Background Overcoming systemic dormancy and initiating secondary tumor grow under unique microenvironmental conditions is a major rate-limiting step in metastatic progression.
