Restoring energy metabolism by NAD + supplement prevents alcohol-induced liver injury and boosts liver regeneration. Food Sci Nutr 2024; 12:5100-5110. [PMID: 39055233 PMCID: PMC11266918 DOI: 10.1002/fsn3.4159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Revised: 03/23/2024] [Accepted: 03/26/2024] [Indexed: 07/27/2024] Open
Abstract
Our previous clinical metabolomics study illustrated that energy metabolism disorder is an underlying pathogenesis mechanism for the development of alcoholic liver disease (ALD). Supplementation of nicotinamide (NAM), the precursor of nicotinamide adenine dinucleotide (NAD+), may restore the energy metabolism homeostasis of ALD and thus serves as potential therapeutics to treat ALD. In this bedside-to-bench study, the protective effect of NAM against ALD was investigated by using the NIAAA mice model (chronic-plus-binge ethanol), and the liver regeneration boosting capability of NAM was evaluated by the partial hepatectomy mice model. Our results showed that NAM supplements not only protected the liver from alcohol-induced injury and improved alcohol-induced mitochondrial structure and function change, but also boosted liver regeneration in postpartial hepatectomy mice by increasing liver NAD+ content. These findings suggested that NAM, a water-soluble form of vitamin B3, can promote liver regeneration and improves liver function by alleviating alcohol-induced energy metabolism disorder.

Phase I/II clinical trial of modulated electro-hyperthermia treatment in patients with relapsed, refractory or progressive heavily treated ovarian cancer. Jpn J Clin Oncol 2019; 49:832-838. [PMID: 31070763 DOI: 10.1093/jjco/hyz071] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 04/08/2019] [Accepted: 04/28/2019] [Indexed: 01/06/2023] Open
Abstract
OBJECTIVE To determine the maximal tolerated dose (MTD) of modulated electro-hyperthermia (mEHT) treatment and to reveal whether mEHT treatment is feasible and effective as second-line therapy in recurrent and progressive ovarian cancer. METHODS Patients were treated with mEHT with dose escalation during the first cycle (two sessions each week for three weeks) to determine the MTD. Additional cycles were carried out with the determined dose. Dose limiting toxicity (DLT) was defined grade ≥ 2: skin burns and inability to endure the hyperthermic state of the study. The Fact-O quality of life scale was used to assess health-related well-being. RESULTS Nineteen patients with recurrent and progressive ovarian cancer were enrolled. In the first cycle of mEHT treatment, no patient developed DLT with applied power up to 110 W, 130 W, and 150 W/day; the 150 W was the maximal applied power. Stable disease was observed in only one patient (12.5%). With median progression of 4.0 months (range, 2-17 months), 18 patients (95%) demonstrated disease progression. With median overall survival of 8.0 months (range, 2-32 months), 18 patients (95%) had died. Physical well-being scores were significantly decreased over the study period, although social, emotional, and functional well-being scores did not significantly change. CONCLUSIONS The mEHT treatment was feasible in patients with recurrent or progressive ovarian cancer without any complication and optimal dose of mEHT treatment was up to 150 W for 1 hour/day.

Abstract
Human skin temperature can vary widely depending on anatomical location and ambient temperature. It is also known that local changes in skin and subcutaneous temperature can affect fat metabolism. This study aimed to explore the potential effects of surrounding thermal environment on fat by investigating cell viability, lipid oxidation, and lipid accumulation in 3T3-L1 adipocytes and palmitate-treated adipocytes after 4h incubation. No significant differences of viability in 3T3-L1 adipocytes were detected under different temperature conditions. Despite no significant increase being observed under warm temperature (39°C) conditions, a similarly significant suppression of intracellular reactive oxygen species (ROS) and lipid peroxidation were found in 3T3-L1 adipocytes and palmitate-treated adipocytes under 4h exposure to cooler temperatures of 31-33°C (P<0.01). ROS, chemically reactive molecules containing oxygen, are currently understood to be a major contributor to oxidantive stress in obesity. Additionally, cooler temperatures (31-33°C) could improve the size of lipid droplets in 3T3-L1 adipocytes (P<0.01), but no significant effect was generated by temperature change on lipid droplets in palmitate-treated adipocytes. In the palmitate-induced adiposity model, although excessive ROS and lipid peroxidation has been attenuated by temperature decrease (P<0.01), it still does not positively modulate lipid droplet size (P>0.05) and remedy the palmitate damage induced cell death (P<0.01). These findings provide preliminary support for potential interventions based on temperature manipulation for cell metabolism of adipocytes.

Abstract
PURPOSE The aim of this study was to evaluate inhibitory effects of L-ascorbic acid-2-O-phosphate-Na(2) (APS), a pro-vitamin C, combined with hyperthermia on adipogenic differentiation of mouse stromal cells, OP9. MATERIALS AND METHODS OP9 preadipocytes were differentiated with serum replacement, administered with APS, and simultaneously treated with hyperthermia using a capacitive-resistive electric transfer (CRet) apparatus, which was conducted repeatedly twice a day. After 2 days, intracellular lipid droplets were stained with Oil Red O, then observed by microscopy and assessed spectrophotometrically. RESULTS After stimulation by serum replacement for 2 days, lipid droplets were accumulated surrounding nucleus of OP9 cells. When APS of 0.15-0.6 mM was administered without hyperthermia, the amount of lipid droplets was markedly suppressed to 50.5%∼-11.3% versus the undifferentiated control, and diminished huge aggregates of lipid droplets. In OP9 cells treated by hyperthermia at 42°C for 0.5 min, 1 min or 3 min in the absence of APS, adipogenesis was suppressed abruptly in a time-dependent manner to 95.4%, 18.7% or -5.5%, respectively. Whereas, the percentage of adipogenesis was 96.8% in OP9 cells treated by mild hyperthermia alone at 41°C for 1 min. The simultaneous application of APS and hyperthermia at 41°C for 1 min markedly suppressed the accumulation of lipid droplets to 25.7%∼-66.2%. By scanning electron microscopy (SEM) observation, the surface of OP9 cells treated with APS and hyperthermia appeared to have the morphological property of undifferentiated OP9 cells. CONCLUSION Combined treatment of APS and mild hyperthermia suppresses adipogenesis in OP9 cells, particularly in lipid droplets accumulation during spontaneous differentiation of OP9 preadipocytes.

Abstract
Long-term heat acclimation (LTHA; 30 days, 34°C) causes phenotypic adaptations that render protection against ischemic/reperfusion insult (I/R, 30 min global ischemia and 40 min reperfusion) via heat acclimation-mediated cross-tolerance (HACT) mechanisms. Short-term acclimation (STHA, 2 days, 34 °C), in contrast, is characterized by cellular perturbations, leading to increased susceptibility to insults. Here, we tested the hypothesis that enhanced mitochondrial respiratory function is part of the acclimatory repertoire and that the 30-day regimen is required for protection via HACT. We subjected isolated hearts and mitochondria from controls (C), STHA, or LTHA rats to I/R, hypoxia/reoxygenation, or Ca2+ overload insults. Mitochondrial function was assessed by measuring O2 consumption, membrane potential (ΔΨm), mitochondrial Ca2+ ([Ca2+]m), ATP production, respiratory chain complex activities, and molecular markers of mitochondrial biogenesis. Our results, combining physiological and biochemical parameters, confirmed that mitochondria from LTHA rats subjected to insults, in contrast to C, preserve respiratory functions (e.g., upon I/R, C mitochondria fueled by glutamate-malate, demonstrated decreases of 81%, 13%, 25%, and 50% in O2/P ratio, ATP production, ΔΨm, and complex I activity, respectively, whereas the corresponding LTHA parameters remained unchanged). STHA mitochondria maintained ΔΨm but did not preserve ATP production. LTHA [Ca2+]m was significantly higher than that of C and STHA and was not affected by the hypoxia/reoxygenation protocol compared with C. Enhanced mitochondrial biogenesis markers, switched-on during STHA coincidentally with enhanced membrane integrity (ΔΨm), were insufficient to confer intact respiratory function upon insult. LTHA was required for respiratory complex I adaptation and HACT. Stabilized higher basal [Ca2+]m and attenuated Ca2+ overload are likely connected to this adaptation.

Abstract
The aim of this study was to investigate the protective effect of naringin, a flavonoid on 3-Nitropropionic acid (3-NP)-induced neurodegeneration through the modulation of intrinsic apoptotic cascade in Wistar rats. 3-NP is an irreversible inhibitor of complex II in the mitochondria. 3-NP-induced neurodegeneration has been widely used as an animal model of Huntington's disease (HD). Increased oxidative stress is one of the major deleterious events in 3-NP-induced neuronal apoptosis. Rats administered with 3-NP showed increase in the levels of lipid peroxidation and protein carbonyl, which was significantly decreased upon naringin treatment (80 mg/kg body weight). 3-NP-induced rats showed decrease in the activities of enzymic antioxidants and reduced levels of non-enzymic antioxidants. Naringin treatment ameliorated the antioxidant status by increasing the activities of enzymic antioxidants and the levels of non-enzymatic antioxidants. 3-NP-induced rats showed decrease in the activities of ATPases in striatum, which was restored to normal level upon naringin treatment. Histopathological observation of the striatal tissue showed protective role of naringin in 3-NP-induced rats. Naringin also reduced the 3-NP-induced apoptosis via decrease in the cytochrome c release from mitochondria and caspase 3 activation as revealed by Western blot. Naringin treatment also decreased the expressions of pro-apoptotic markers like Bad and Bax. Further, naringin antagonized 3-NP-induced decrease in Bcl-2 mRNA expression. The results of this study show evidence on the neuroprotective effect of naringin against 3-NP-induced neuronal apoptosis through its antioxidant and anti-apoptotic effects.

Abstract
Huntington's disease (HD) is an inheritable autosomal-dominant disorder whose causal mechanisms remain unknown. Experimental models have begun to uncover these pathways, thus helping to understand the mechanisms implicated and allowing for the characterization of potential targets for new therapeutic strategies. 3-Nitropropionic acid is known to produce in animals behavioural, biochemical and morphologic changes similar to those occurring in HD. For this reason, this phenotypic model is gaining attention as a valuable tool to mimick this disorder and further developing new therapies. In this review, we will focus on the past and present research of this molecule, to finally bring a perspective on what will be next in this promising field of study.
