The causal relationships between mitochondria and six types of cancer: a Mendelian randomization study [PDF]
BMC CancerBackground Mitochondria play a multifaceted role in tumorigenesis, influencing energy metabolism, redox balance, and apoptosis. However, whether mitochondrial traits causally affect cancer risk remains unclear.

Engineering an Overflow-Responsive Regulation System for Balancing Cellular Redox and Optimizing Microbial Production. [PDF]
Biotechnol BioengABSTRACT Escherichia coli accumulates acetate as a byproduct in fast growth aerobic conditions when using glucose as carbon source. This phenomenon, known as overflow metabolism, has negative impacts on cell growth and protein expression, also causes carbon loss during biosynthesis in most microbial production scenarios. In this study, we regarded the “

The Link between Mitochondrial Dysfunction and Sarcopenia: An Update Focusing on the Role of Pyruvate Dehydrogenase Kinase 4 [PDF]
Diabetes & Metabolism Journal, 2023 Sarcopenia, defined as a progressive loss of muscle mass and function, is typified by mitochondrial dysfunction and loss of mitochondrial resilience. Sarcopenia is associated not only with aging, but also with various metabolic diseases characterized by ...

The Role of Pyruvate Dehydrogenase Kinase in Diabetes and Obesity [PDF]
Diabetes & Metabolism Journal, 2014 The pyruvate dehydrogenase complex (PDC) is an emerging target for the treatment of metabolic syndrome. To maintain a steady-state concentration of adenosine triphosphate during the feed-fast cycle, cells require efficient utilization of fatty acid and ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression
Hepatology, EarlyView., 2022 Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease
Hepatology, EarlyView., 2022 RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease. Abstract Background and Aims Receptor‐interacting protein kinase 3 (RIPK3) mediates NAFLD progression, but its metabolic function is unclear. Here, we aimed to investigate the role of RIPK3 in modulating mitochondria function, coupled with lipid droplet (LD)

Inferring Compensatory Kinase Networks in Yeast using Prolog [PDF]
EPTCS 385, 2023, pp. 260-273, 2023 Signalling pathways are conserved across different species, therefore making yeast a model organism to study these via disruption of kinase activity. Yeast has 159 genes that encode protein kinases and phosphatases, and 136 of these have counterparts in humans.

LIGHT-SABRE hyperpolarizes 1-^{13}C-pyruvate continuously, without magnetic field cycling [PDF]
J. Phys. Chem. C 2023, 127, 14, 6744-6753, 2023 Nuclear spin hyperpolarization enables real-time observation of metabolism and intermolecular interactions in vivo. 1-13C-Pyruvate is the leading hyperpolarized tracer currently under evaluation in several clinical trials as a promising molecular imaging agent.

Incorporating expression data in metabolic modeling: a case study of lactate dehydrogenase [PDF]
J Theor Biol 240: 464-474 (2006), 2005 Integrating biological information from different sources to understand cellular processes is an important problem in systems biology. We use data from mRNA expression arrays and chemical kinetics to formulate a metabolic model relevant to K562 erythroleukemia cells. MAP kinase pathway activation alters the expression of metabolic enzymes in K562 cells.
