Dual Inhibition of the Lactate Transporters MCT1 and MCT4 Is Synthetic Lethal with Metformin due to NAD+ Depletion in Cancer Cells

open access: yesCell Reports, 2018
Summary: Highly glycolytic cancer cells prevent intracellular acidification by excreting the glycolytic end-products lactate and H+ via the monocarboxylate transporters 1 (MCT1) and 4 (MCT4).

Lactate Limits T Cell Proliferation via the NAD(H) Redox State

open access: yesCell Reports, 2020
Summary: Immune cell function is influenced by metabolic conditions. Low-glucose, high-lactate environments, such as the placenta, gastrointestinal tract, and the tumor microenvironment, are immunosuppressive, especially for glycolysis-dependent effector

Stimulation of Enzyme Reaction Rates by Crystalline Substrate Irradiation: Dependence on Identity of Irradiated Substance [PDF]

open access: yesarXiv, 2013
The study reported here concerns a phenomenon, discovered and extensively investigated by Sorin Comorosan, wherein enzyme initial reaction rates are enhanced as a consequence of incorporation of solutions derived from previously irradiated crystalline material into the reaction medium.

Common and rare variants associating with serum levels of creatine kinase and lactate dehydrogenase

open access: yesNature Communications, 2016
Creatine kinase (CK) and lactate dehydrogenase (LDH) are widely used markers of tissue damage. To search for sequence variants influencing serum levels of CK and LDH, 28.3 million sequence variants identified through whole-genome sequencing of 2,636 ...

Microstructure, Mechanical Properties, and Antibacterial Performance of Novel Fe‐Mn‐Zn Nanocrystalline Alloys Produced by Mechanical Alloying

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the development of Fe‐Mn‐Zn nanocrystalline alloys (0–9 wt% Zn) by mechanical alloying and subsequently hot pressing. Their microstructure, density, hardness, wear resistance, corrosion behavior, and antibacterial properties are systematically examined.

Preferential utilization of NADPH as the endogenous electron donor for NAD(P)H:quinone oxidoreductase 1 (NQO1) in intact pulmonary arterial endothelial cells [PDF]

open access: yes, 2009
The goal was to determine whether endogenous cytosolic NAD(P)H:quinone oxidoreductase 1 (NQO1) preferentially uses NADPH or NADH in intact pulmonary arterial endothelial cells in culture.

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation

A heuristic approach for lactate threshold estimation for training decision-making: An accessible and easy to use solution for recreational runners [PDF]

open access: yes, 2019
In this work, a heuristic as operational tool to estimate the lactate threshold and to facilitate its integration into the training process of recreational runners is proposed. To do so, we formalize the principles for the lactate threshold estimation from empirical data and an iterative methodology that enables experience based learning. This strategy

Characterization of three 2-hydroxy-acid dehydrogenases in the context of a biotechnological approach to short-circuit photorespiration [PDF]

open access: yes, 2010
Photorespiration results from the incorporation of oxygen into ribulose-1,5-bisphosphate due to the failure of RuBisCO to properly discriminate between oxygen and carbon dioxide.

Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

open access: yesAdvanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.
