SIRT5 Activation and Inorganic Phosphate Binding Reduce Cancer Cell Vitality by Modulating Autophagy/Mitophagy and ROS

Antioxidants, 2023
Cancer cells show increased glutamine consumption. The glutaminase (GLS) enzyme controls a limiting step in glutamine catabolism. Breast tumors, especially the triple-negative subtype, have a high expression of GLS. Our recent study demonstrated that GLS

Activation of the NRF2 antioxidant program generates an imbalance in central carbon metabolism in cancer [PDF]

, 2018
During tumorigenesis, the high metabolic demand of cancer cells results in increased production of reactive oxygen species. To maintain oxidative homeostasis, tumor cells increase their antioxidant production through hyperactivation of the NRF2 pathway ...

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

The oncogenic transcription factor c-Jun regulates glutaminase expression and sensitizes cells to glutaminase-targeted therapy

Nature Communications, 2016
Cancer cells have previously been shown to be addicted to glutamine and glutaminase enzyme activity. Here, the authors show that overexpression of the JUN proto-oncogene in breast cancer cells regulates glutaminaseexpression and is sufficient to confer ...

Brimonidine Therapy for Protection From Noise-Induced Hearing Loss. [PDF]

Aging Cell
In this study, we demonstrate that brimonidine protects against noise‐induced hearing loss in young mice by suppressing glutamate synthesis and vesicle transport, thereby reducing excitotoxicity and preserving synaptic integrity. Such early intervention may prevent age‐related hearing loss, highlighting brimonidine's potential as a therapeutic agent ...

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.

CRISPR Cas9-mediated ablation of pyruvate carboxylase gene in colon cancer cell line HT-29 inhibits growth and migration, induces apoptosis and increases sensitivity to 5-fluorouracil and glutaminase inhibitor

Frontiers in Oncology, 2022
Pyruvate carboxylase (PC) is an important anaplerotic enzyme that replenishes the tricarboxylic acid cycle (TCA) intermediates. It prevents the collapse of the TCA cycle upon its intermediates are removed during high anabolic demand.

N6‐Methyladenosine (m6A) in Liver Disease: Pathogenic Mechanisms and Therapeutic Potential

iNew Medicine, EarlyView.
ABSTRACT Accumulating evidence highlights the critical role of epigenetic modifications, particularly N6‐methyladenosine (m6A), in liver disease. As the most abundant RNA modification in eukaryotic cells, m6A is dynamically regulated by multicomponent m6A methyltransferases (e.g., METTL3 and METTL14), demethylases (FTO and ALKBH5), and m6A‐binding ...

Modeling cancer metabolism on a genome scale [PDF]

, 2015
Cancer cells have fundamentally altered cellular metabolism that is associated with their tumorigenicity and malignancy. In addition to the widely studied Warburg effect, several new key metabolic alterations in cancer have been established over the last

p63 regulates glutaminase 2 expression [PDF]

Cell Cycle, 2013
The transcription factor p63 is critical for many biological processes, including development and maintenance of epidermal tissues and tumorigenesis. Here, we report that the TAp63 isoforms regulate cell metabolism through the induction of the mitochondrial glutaminase 2 (GLS2) gene both in primary cells and tumor cell lines.
