Characterization of the metabolic shift between oxidative and fermentative growth in Saccharomyces cerevisiae by comparative ¹³C flux analysis

Microbial Cell Factories, 2005
Background One of the most fascinating properties of the biotechnologically important organism Saccharomyces cerevisiae is its ability to perform simultaneous respiration and fermentation at high growth rate even under fully aerobic conditions.

Lactylated SPTAN1 Accelerates Hepatocellular Carcinoma Progression by Promoting NOTCH1/HES1 Activation and Immunosuppression

Advanced Science, EarlyView.
This study identifies SPTAN1‐kla as a novel oncogenic driver in HBV‐driven HCC, linking metabolic, epigenetic, and immune mechanisms. SPTAN1‐kla promotes HCC progression via NOTCH1/HES1 activation and immunosuppression. Findings highlight that targeting SPTAN1‐kla provides a framework for HCC treatment to improve clinical outcomes in HBV infected ...

Abnormal lipid droplets accumulation induced cognitive deficits in obstructive sleep apnea syndrome mice via JNK/SREBP/ACC pathway but not through PDP1/PDC pathway

Molecular Medicine, 2022
The mechanisms of chronic intermittent hypoxia (CIH)-induced cognitive deficits remain unclear. Here, our study found that about 3 months CIH treatment induced lipid droplets (LDs) accumulation in hippocampal nerve and glia cells of C57BL/6 mice, and ...

Binding of pyruvate dehydrogenase to the core of the human pyruvate dehydrogenase complex [PDF]

FEBS Letters, 2008
In human (h) pyruvate dehydrogenase complex (PDC) the pyruvate dehydrogenase (E1) is bound to the E1‐binding domain of dihydrolipoamide acetyltransferase (E2). The C‐terminal surface of the E1β subunit was scanned for the negatively charged residues involved in binding with E2.

Amphiregulin and Epiregulin Confer Radioresistance in Esophageal Squamous Cell Carcinoma Through Oxidative Phosphorylation

Advanced Science, EarlyView.
Oxidative phosphorylation (OXPHOS) activity serves as a critical metabolic determinant of radiotherapy outcomes in esophageal squamous cell carcinoma (ESCC). The CEBPB/AREG/EREG axis drives radioresistance in ESCC by reprogramming OXPHOS. AREG and EREG function as predictive biomarkers for nCRT response and prognosis of ESCC patients.

Dynamic Imaging of LDH Inhibition in Tumors Reveals Rapid In Vivo Metabolic Rewiring and Vulnerability to Combination Therapy

Cell Reports, 2020
Summary: The reliance of many cancers on aerobic glycolysis has stimulated efforts to develop lactate dehydrogenase (LDH) inhibitors. However, despite significant efforts, LDH inhibitors (LDHi) with sufficient specificity and in vivo activity to ...

USP9X as a Candidate Mediator of Prenatal Aspirin‐Induced Ovarian Reserve Reduction in Offspring Mice

Advanced Science, EarlyView.
This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

Thermodynamics in cancers: opposing interactions between PPAR gamma and the canonical WNT/beta-catenin pathway

Clinical and Translational Medicine, 2017
Cancer cells are the site of numerous metabolic and thermodynamic abnormalities. We focus this review on the interactions between the canonical WNT/beta-catenin pathway and peroxisome proliferator-activated receptor gamma (PPAR gamma) in cancers and ...

Phenylbutyrate increases activity of pyruvate dehydrogenase complex

Oncotarget, 2013
Altered metabolism is an important hallmark of cancer cells and confers them a selective advantage for survival and proliferation. Metabolism in cancer cells is shifted towards glycolysis and decreased dependence on mitochondrial glucose oxidation, a phenomenon known as ‘Warburg effect’ (aerobic glycolysis).
