Programming Skeletal Muscle Metabolic Flexibility in Offspring of Male Rats in Response to Maternal Consumption of Slow Digesting Carbohydrates during Pregnancy [PDF]

, 2020
Skeletal muscle plays a relevant role in metabolic flexibility and fuel usage and the associated muscle metabolic inflexibility due to high-fat diets contributing to obesity and type 2 diabetes.

Dichloroacetate for Cancer Treatment: Some Facts and Many Doubts

Pharmaceuticals
Rarely has a chemical elicited as much controversy as dichloroacetate (DCA). DCA was initially considered a dangerous toxic industrial waste product, then a potential treatment for lactic acidosis. However, the main controversies started in 2008 when DCA

Huzhangoside A Suppresses Tumor Growth through Inhibition of Pyruvate Dehydrogenase Kinase Activity

Cancers, 2019
Aerobic glycolysis is one of the important metabolic characteristics of many malignant tumors. Pyruvate dehydrogenase kinase (PDHK) plays a key role in aerobic glycolysis by phosphorylating the E1α subunit of pyruvate dehydrogenase (PDH). Hence, PDHK has

Glycolysis‐Derived Lactate Induces ACSL4 Expression and Lactylation to Activate Ferroptosis during Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Glycolysis‐derived lactate activates nucleus pulposus cell ferroptosis via Histon H3K18la‐mediated ACSL4 transcription and ACSL4 lactylation and aggravate intervertebral disc degeneration. Inhibiting glycolysis via gene silencing or chemical intervention reduces the production of lactate and ameliorates ferroptosis activation and nucleus pulposus ...

The transglutaminase type 2 and pyruvate kinase isoenzyme M2 interplay in autophagy regulation [PDF]

, 2015
Autophagy is a self-degradative physiological process by which the cell removes worn-out or damaged components. Constant at basal level it may become highly active in response to cellular stress. The type 2 transglutaminase (TG2), which accumulates under

Nuclear‐Localized BCKDK Facilitates Homologous Recombination Repair to Support Breast Cancer Progression and Therapy Resistance

Advanced Science, EarlyView.
Under DNA damage, tumor cells rely on efficient DNA repair for survival and therapy resistance. This study has demonstrated that BCKDK localizes to breast cancer cell nuclei, where it binds to and phosphorylates RNF8, thereby blocking ubiquitin‐mediated degradation of RAD51 and enhancing HRR. A selective BCKDK inhibitor synergizes with clinical agents,

Pyruvate Dehydrogenase Kinase 4 [PDF]

Diabetes, 2008
OBJECTIVE—Pyruvate dehydrogenase complex (PDC) serves as the metabolic switch between glucose and fatty acid utilization. PDC activity is inhibited by PDC kinase (PDK). PDC shares the same substrate, i.e., pyruvate, as glyceroneogenesis, a pathway controlling fatty acid release from white adipose tissue (WAT).

Inhibition of pyruvate dehydrogenase kinase enhances the antitumor efficacy of oncolytic reovirus.

Cancer Research, 2019
Oncolytic viruses (OV) such as reovirus preferentially infect and kill cancer cells. Thus, the mechanisms that dictate the susceptibility of cancer cells to OV-induced cytotoxicity hold the key to their success in clinics.

A Live Cell Imaging‐Compatible Bioreactor for the Interrogation of Cellular Responses to Modulated Flow Conditions

Advanced Science, EarlyView.
An open‐source, low‐cost 3D perfusion system integrating bioprinted scaffolds and live‐imaging overcomes 2D culture limitations. Modeling the cerebrospinal fluid‐filled subarachnoid space, it reveals flow‐dependent focal adhesion kinase activation in meningothelial cells, demonstrating a powerful platform for studying mechanobiology and creating ...

Effects of alpha-ketoisovalerate on bovine heart pyruvate dehydrogenase complex and pyruvate dehydrogenase kinase.

Journal of Biological Chemistry, 1986
The regulatory effects of alpha-ketoisovalerate on purified bovine heart pyruvate dehydrogenase complex and endogenous pyruvate dehydrogenase kinase were investigated. Incubation of pyruvate dehydrogenase complex with 0.125 to 10 mM alpha-ketoisovalerate caused an initial lag in enzymatic activity, followed by a more linear but inhibited rate of NADH ...
