Integrated amplification of NADPH-regenerating modules enhances cytidine biosynthesis in Escherichia coli

Synthetic and Systems Biotechnology
In Escherichia coli, cofactor imbalance serves as a crucial limiting factor in cytidine biosynthesis, with nicotinamide adenine dinucleotide phosphate (NADPH) insufficiency representing the principal metabolic barrier.

Constitutive NADPH-Dependent Electron Transferase Activity of the Nox4 Dehydrogenase Domain

Biochemistry, 2010
NADPH oxidase 4 (Nox4) is constitutively active, while Nox2 requires the cytosolic regulatory subunits p47(phox) and p67(phox) and activated Rac with activation by phorbol 12-myristate 13-acetate (PMA). This study was undertaken to identify the domain on Nox4 that confers constitutive activity.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

A nanoplatform that induces dual‐amino acid deprivation to reverse tumor immunosuppression and enhance metabolic immunotherapy

BMEMat, EarlyView.
ZIF‐8‐based nanoparticles co‐delivering CB‐839 (glutaminase inhibitor) and 1‐MT (IDO1 inhibitor), dual‐targeting glutamine/tryptophan metabolism to induce immunogenic cell death, activate STING, block kynurenine production, reverse immunosuppression, and enhance cancer immunotherapy to suppress primary/distant tumors.

Crystal Structure of NADPH-Dependent Methylglyoxal Reductase Gre2 from Candida Albicans

Crystals, 2019
Gre2 is a key enzyme in the methylglyoxal detoxification pathway; it uses NADPH or NADH as an electron donor to reduce the cytotoxic methylglyoxal to lactaldehyde. This enzyme is a member of the short-chain dehydrogenase/reductase (SDR) superfamily whose

Enhanced strategies for cuproptosis‐like death in bacterial infection treatment

BMEMat, EarlyView.
This review summarizes and examines the molecular mechanisms underlying cuproptosis‐like death. Furthermore, multi‐strategy efficacy enhancement and potential enhancement approaches are analyzed. Abstract Copper, a classical antibacterial metal, has long been of interest and widely used in medical and public health applications.

A comparative transcriptomic, fluxomic and metabolomic analysis of the response of Saccharomyces cerevisiae to increases in NADPH oxidation

BMC Genomics, 2012
Background Redox homeostasis is essential to sustain metabolism and growth. We recently reported that yeast cells meet a gradual increase in imposed NADPH demand by progressively increasing flux through the pentose phosphate (PP) and acetate pathways and

An all‐in‐one fucosylated gold nanocluster probe enables NIR‐II imaging and multi‐mechanistic therapy of acute kidney injury

BMEMat, EarlyView.
This study developed a fucoside‐targeted gold nanocluster probe that enables early NIR‐II imaging and multi‐mechanistic therapy for acute kidney injury, effectively mitigating oxidative stress, modulating inflammatory responses, and inhibiting ferroptosis to improve renal outcomes. Abstract Acute kidney injury (AKI) remains a life‐threatening condition

A comparative analysis of NADPH supply strategies in Saccharomyces cerevisiae: Production of d-xylitol from d-xylose as a case study

Metabolic Engineering Communications
Enhancing the supply of the redox cofactor NADPH in metabolically engineered cells is a critical target for optimizing the synthesis of many product classes, such as fatty acids or terpenoids. In S.

How developmental stressors affect mitochondrial respiratory function: a systematic review and meta‐analysis

Biological Reviews, EarlyView.
ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.
