Abstract
Maintenance of the mitochondrial thiol redox state is essential for cell survival. However, we lack a comprehensive understanding of the redox response to mitochondrial glutathione depletion. We developed a mitochondria-penetrating peptide, mtCDNB, to specifically deplete mitochondrial glutathione. A genome-wide CRISPR/Cas9 screen in tandem with mtCDNB treatment was employed to uncover regulators of the redox response to mitochondrial glutathione depletion. We identified nucleoside diphosphate kinase 3 (NME3) as a regulator of mitochondrial dynamics. We show that NME3 is recruited to the mitochondrial outer membrane when under redox stress. In the absence of NME3, there is impaired mitophagy, which leads to the accumulation of dysfunctional mitochondria. NME3 knockouts depleted of mitochondrial glutathione have increased mitochondrial ROS production, accumulate mtDNA lesions, and present a senescence-associated secretory phenotype. Our findings suggest a novel role for NME3 in selecting mitochondria for degradation through mitophagy under conditions of mitochondrial redox stress.

Wang ZH, Wang J, Liu F, Sun S, Zheng Q, Hu X, Yin Z, Xie C, Wang H, Wang T, Zhang S, Wang YP. THAP3 recruits SMYD3 to OXPHOS genes and epigenetically promotes mitochondrial respiration in hepatocellular carcinoma. FEBS Lett 2024; 598:1513-1531. [PMID: 38664231 DOI: 10.1002/1873-3468.14889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 03/27/2024] [Accepted: 03/31/2024] [Indexed: 06/27/2024]
Abstract
Mitochondria harbor the oxidative phosphorylation (OXPHOS) system to sustain cellular respiration. However, the transcriptional regulation of OXPHOS remains largely unexplored. Through the cancer genome atlas (TCGA) transcriptome analysis, transcription factor THAP domain-containing 3 (THAP3) was found to be strongly associated with OXPHOS gene expression. Mechanistically, THAP3 recruited the histone methyltransferase SET and MYND domain-containing protein 3 (SMYD3) to upregulate H3K4me3 and promote OXPHOS gene expression. The levels of THAP3 and SMYD3 were altered by metabolic cues. They collaboratively supported liver cancer cell proliferation and colony formation. In clinical human liver cancer, both of them were overexpressed. THAP3 positively correlated with OXPHOS gene expression. Together, THAP3 cooperates with SMYD3 to epigenetically upregulate cellular respiration and liver cancer cell proliferation.

Abstract
Certain cancer cells within solid tumors experience hypoxia, rendering them incapable of oxidative phosphorylation (OXPHOS). Despite this oxygen deficiency, these cells exhibit biochemical pathway activity that relies on NAD+. This mini-review scrutinizes the persistent, residual Complex I activity that oxidizes NADH in the absence of oxygen as the electron acceptor. The resulting NAD+ assumes a pivotal role in fueling the α-ketoglutarate dehydrogenase complex, a critical component in the oxidative decarboxylation branch of glutaminolysis - a hallmark oncometabolic pathway. The proposition is that through glutamine catabolism, high-energy phosphate intermediates are produced via substrate-level phosphorylation in the mitochondrial matrix substantiated by succinyl-CoA ligase, partially compensating for an OXPHOS deficiency. These insights provide a rationale for exploring Complex I inhibitors in cancer treatment, even when OXPHOS functionality is already compromised.

Abstract
Reactive oxygen species (ROS) constitute a spectrum of oxygenic metabolites crucial in modulating pathological organism functions. Disruptions in ROS equilibrium span various diseases, and current insights suggest a dual role for ROS in tumorigenesis and the immune response within cancer. This review rigorously examines ROS production and its role in normal cells, elucidating the subsequent regulatory network in inflammation and cancer. Comprehensive synthesis details the documented impacts of ROS on diverse immune cells. Exploring the intricate relationship between ROS and cancer immunity, we highlight its influence on existing immunotherapies, including immune checkpoint blockade, chimeric antigen receptors, and cancer vaccines. Additionally, we underscore the promising prospects of utilizing ROS and targeting ROS modulators as novel immunotherapeutic interventions for cancer. This review discusses the complex interplay between ROS, inflammation, and tumorigenesis, emphasizing the multifaceted functions of ROS in both physiological and pathological conditions. It also underscores the potential implications of ROS in cancer immunotherapy and suggests future research directions, including the development of targeted therapies and precision oncology approaches. In summary, this review emphasizes the significance of understanding ROS-mediated mechanisms for advancing cancer therapy and developing personalized treatments.

Abstract
In this work, we have developed a nanocomposite consisting of horseradish peroxidase (HRP)-encapsulated 2D Zn-Co zeolite imidazole framework (ZIF) nanosheets strung on a ZnCoO nanowire array on a Ti support (denoted as 2D-Zn/Co-ZIF(HRP)|ZnCoO|Ti). This nanocomposite was then applied to constructing an electrochemical biosensor for detecting H2O2 derived from O2∙- released by mitochondria in living cells. This sensing platform shows excellent catalytic performance towards H2O2, attributable to the enzyme/metal-catalytic effect of HRP and Zn/Co-ZIF. The unique nano-string structure alleviates the aggregation of Zn/Co-ZIF nanosheets, readily exposes the catalytic active sites, protects the bioactivity of HRP, and reduces the charge/mass transfer pathway within Zn/Co-ZIF. The 2D-Zn/Co-ZIF(HRP)|ZnCoO|Ti biosensor offers two linear ranges of 0.2-10 μ M and 10-1100 μ M, a limit of detection of 0.082 μ M, a sensitivity of 3.3 mA mM-1 cm-2, good selectivity and stability over 40 days for H2O2 detection. After treating with specific mitochondrial complex inhibitors, the chronoamperometric results at the 2D-Zn/Co-ZIF(HRP)|ZnCoO|Ti confirmed complex I and III within the mitochondria electron transfer chain as the main electron leakage sites. This biosensor may contribute to the development of diagnostic health-care devices that shed light on the precaution and even treatment of oxidative stress diseases.

Oncol Lett 2023; 26:327.

Abstract
Gastric cancer is one of the most lethal cancers worldwide. Research has focused on exploring natural medicines to improve the systematic chemotherapy for gastric cancer. Luteolin, a natural flavonoid, possesses anticancer activities. Nevertheless, the mechanism of the anticancer effects of luteolin is still not clear. The present study aimed to verify the inhibitory effect of luteolin on gastric cancer HGC-27, MFC and MKN-45 cells and to explore the underlying mechanism. A Cell Counting Kit-8 cell viability assay, flow cytometry, western blot, an ATP content assay and an enzyme activity testing assay were used. Luteolin inhibited the proliferation of gastric cancer HGC-27, MFC and MKN-45 cells. Further, it impaired mitochondrial integrity and function by destroying the mitochondrial membrane potential, downregulating the activities of mitochondrial electron transport chain complexes (mainly complexes I, III and V), and unbalancing the expression of B cell lymphoma-2 family member proteins, eventually leading to apoptosis of gastric cancer HGC-27, MFC and MKN-45 cells. The intrinsic apoptosis pathway was involved in luteolin's anti-gastric cancer effects. Furthermore, mitochondria were the main target in luteolin-induced gastric cancer apoptosis. The present study may provide a theoretical basis for the research on the effect of luteolin on the mitochondrial metabolism in cancer cells, and pave the way for its practical application in the future.

Melatonin: highlighting its use as a potential treatment for SARS-CoV-2 infection. Cell Mol Life Sci 2022; 79:143.

Abstract
Numerous pharmaceutical drugs have been repurposed for use as treatments for COVID-19 disease. These drugs have not consistently demonstrated high efficacy in preventing or treating this serious condition and all have side effects to differing degrees. We encourage the continued consideration of the use of the antioxidant and anti-inflammatory agent, melatonin, as a countermeasure to a SARS-CoV-2 infection. More than 140 scientific publications have identified melatonin as a likely useful agent to treat this disease. Moreover, the publications cited provide the rationale for the use of melatonin as a prophylactic agent against this condition. Melatonin has pan-antiviral effects and it diminishes the severity of viral infections and reduces the death of animals infected with numerous different viruses, including three different coronaviruses. Network analyses, which compared drugs used to treat SARS-CoV-2 in humans, also predicted that melatonin would be the most effective agent for preventing/treating COVID-19. Finally, when seriously infected COVID-19 patients were treated with melatonin, either alone or in combination with other medications, these treatments reduced the severity of infection, lowered the death rate, and shortened the duration of hospitalization. Melatonin’s ability to arrest SARS-CoV-2 infections may reduce health care exhaustion by limiting the need for hospitalization. Importantly, melatonin has a high safety profile over a wide range of doses and lacks significant toxicity. Some molecular processes by which melatonin resists a SARS-CoV-2 infection are summarized. The authors believe that all available, potentially beneficial drugs, including melatonin, that lack toxicity should be used in pandemics such as that caused by SARS-CoV-2.
