Hydroxycitric acid and capsaicin combination alleviates obesity-induced testicular apoptosis, oxidative stress and inflammation. Syst Biol Reprod Med 2024; 70:20-37.

Abstract
Recent research in rodents suggests that oxidative stress, inflammation, and apoptosis in the testes caused by high-fat diets (HFD) are a cause of male infertility. To investigate the therapeutic efficacy of the combination of hydroxycitric acid and capsaicin (HCC) against male reproductive disorders, we developed an HFD-induced obese rat model. Rats received HFD supplementation for 21 weeks, which induced obesity. From week 16, HCC (100 mg/kg body weight) was administered to investigate its potential to treat testicular toxicity. According to the results of the current study, treatment of obese rats with HCC improved their sperm quality, increased the production of testosterone, follicle-stimulating hormone, and luteinizing hormone and significantly increased the activities of steroidogenic enzymes and corresponding mRNA levels. In addition, HCC decreased lipid peroxidation and nitric oxide levels in both spermatozoa and testes while increasing the expression of mRNA for the antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase in the testes, which in turn reduced oxidative stress in the testes. Moreover, after HCC treatment, testicular tissues showed a remarkable decrease in mRNA levels responsible for inflammation (TNF-α, IL-6, NF-κB) and apoptosis (Bax and Bcl-2). Our results suggest that HCC may alleviate obesity-induced male reproductive dysfunction by attenuating oxidative stress, inflammation, and apoptosis in the testes of HFD-induced obese male rats.

Abstract
Diabetes mellitus (DM) is a metabolic illness defined by elevated blood glucose levels, mediating various tissue alterations, including the dysfunction of vital organs. Diabetes mellitus (DM) can lead to many consequences that specifically affect the brain, heart, and kidneys. These issues are known as neuropathy, cardiomyopathy, and nephropathy, respectively. Inflammation is acknowledged as a pivotal biological mechanism that contributes to the development of various diabetes consequences. NF-κB modulates inflammation and the immune system at the cellular level. Its abnormal regulation has been identified in several clinical situations, including cancer, inflammatory bowel illnesses, cardiovascular diseases, and Diabetes Mellitus (DM). The purpose of this review is to evaluate the potential impact of NF-κB on complications associated with DM. Enhanced NF-κB activity promotes inflammation, resulting in cellular harm and compromised organ performance. Phytochemicals, which are therapeutic molecules, can potentially decline the NF-κB level, therefore alleviating inflammation and the progression of problems correlated with DM. More importantly, the regulation of NF-κB can be influenced by various factors, such as TLR4 in DM. Highlighting these factors can facilitate the development of novel therapies in the future.

Phytoformulation with hydroxycitric acid and capsaicin protects against high-fat-diet-induced obesity cardiomyopathy by reducing cardiac lipid deposition and ameliorating inflammation and apoptosis in the heart. J Tradit Complement Med 2024; 14:162-172. [PMID: 38481548 PMCID: PMC10927456 DOI: 10.1016/j.jtcme.2023.08.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 06/15/2023] [Accepted: 08/23/2023] [Indexed: 06/24/2024] Open
Abstract
BACKGROUND AND AIM Phytoformulation therapy is a pioneering strategy for the treatment of metabolic disorders and related diseases. The aim of the present study was to investigate the protective effect of a phytoformulation consisting of hydroxycitric acid and capsaicin against obesity-related cardiomyopathy. EXPERIMENTAL PROCEDURE Sprague-Dawley rats were fed HFD for 21 weeks, and phytoformulation (100 mg/kg body weight) was administered orally for 45 days starting at week 16. RESULTS AND CONCLUSION We found that HFD supplementation resulted in significant hyperglycemia and caused an increase in cardiac lipid deposition, inflammation and apoptosis in the heart. Phytoformulation therapy not only significantly decreased blood levels of glucose, cholesterol, triglycerides, free fatty acids, and inflammatory cytokines in obese rats, but also protected cardiac tissue, as shown by histological analysis. Conversely, phytoformulation therapy decreased mRNA levels for sterol regulatory element-binding factor 1, fatty acid synthase, acetyl-CoA carboxylase, and fatty acid binding protein 1 genes involved in fatty acid synthesis and absorption in obese rats. It increased the levels of lysosomal acid lipase, hormone-sensitive lipase, and lipoprotein lipase genes involved in fatty acid degradation in the heart. In addition, the phytoformulation improved cardiac inflammation and apoptosis by downregulating the genes nuclear factor kappa-light-chain enhancer of activated B cells (NF-kB), tumour necrosis factor α, interleukin-6, toll-like receptor-4 (TLR-4), BCL2-associated X and caspase-3. In conclusion, our results show that the phytoformulation improved insulin sensitivity and attenuated myocardial lipid accumulation, inflammation, and apoptosis in the heart of HFD-induced obese rats by regulating fatty acid metabolism genes and downregulating NF-kB/TLR-4/caspase-3.

Abstract
BACKGROUND Obesity is a complex multifactorial disease in which the accumulation of excess body fat has adverse health effects, as it can increase the risk of several problems, including infertility, in both men and women. Obesity and infertility have risen together in recent years. Against this background, the present review aims to highlight the impact of obesity on infertility and the underlying pathophysiology of obesity-related infertility (ORI) in men and women, and to provide readers with knowledge of current trends in the effective development of phytotherapeutics for its treatment. METHODS We thoroughly searched in PubMed, MEDLINE, Scopus, EMBASE, and Google Scholar to find all relevant papers on ORI and the therapeutic effects of phytotherapeutics on ORI in men and women. RESULTS The extensive search of the available literature revealed that obesity affects reproductive function through several complex mechanisms such as hyperlipidaemia, hyperinsulinaemia, hyperandrogenism, increased body mass index, disruption of the hormonal milieu, systemic inflammation, oxidative stress, alterations in epigenetics and dysbiosis. On the other hand, several studies reported that phytotherapeutics has a broad therapeutic spectrum of action by improving sex hormone homeostasis, ovarian dysfunction, menstrual cycle and inhibiting ovarian hyperplasia, as well as down-regulating ovarian apoptosis, inflammation and oxidative stress, and controlling metabolic dysfunction in obese women. Male infertility is also addressed by phytotherapeutics by suppressing lipogenesis, increasing testosterone, 3β-HSD and 17β-HSD levels, improving sperm parameters and attenuating testicular dyslipidaemia, oxidative stress, inflammation and germ cell apoptosis. CONCLUSIONS In the present review, we discussed the effects of obesity on reproductive dysfunction in men and women and the underlying pathophysiology of ORI. In addition, the therapeutic effect of phytotherapeutics against ORI was highlighted.

Abstract
Diabetes mellitus (DM) is one of the most prevalent metabolic disorders that poses a global threat to human health. It can lead to complications in multiple organs and tissues, owing to its wide-ranging impact on the human body. Diabetic cardiomyopathy (DCM) is a specific cardiac manifestation of DM, which is characterized by heart failure in the absence of coronary heart disease, hypertension and valvular heart disease. Given that oxidative stress is a key factor in the pathogenesis of DCM, intervening to mitigate oxidative stress may serve as a therapeutic strategy for managing DCM. Naringenin is a natural product with anti-oxidative stress properties that can suppress oxidative damage by regulating various oxidative stress signaling pathways. In this review, we address the relationship between oxidative stress and its primary signaling pathways implicated in DCM, and explores the therapeutic potential of naringenin in DCM.

Abstract
INTRODUCTION Linalool is a monoterpene that occurs naturally in various aromatic plants and is identified in our previous study as a potential candidate for protection against high-fat diet (HFD)-induced metabolic dysfunction-associated steatotic liver disease (MASLD). However, little is known about its direct effects on hepatic lipid metabolism and oxidative stress. Therefore, this study aims to investigate the therapeutic effect of linalool against MASLD and the underlying mechanism. METHODS To establish a rat model of MASLD, male Wistar rats were fed HFD for 16 weeks and orally administered linalool (100 mg/kg body weight) for 45 days starting from week 14. RESULTS Linalool significantly reduced HFD-induced liver lipid accumulation and restored altered adipokine levels. Mechanistically, linalool downregulated the mRNA expression of sterol regulatory element binding protein 1 and its lipogenesis target genes fatty acid synthase and acetyl-CoA carboxylase, and upregulated the mRNA expression of genes involved in fatty acid oxidation (peroxisome proliferator-activated receptor (PPAR)-alpha [PPAR-α], lipoprotein lipase and protein kinase B [Akt]) as well as the upstream mediators sirtuin 1 (Sirt1) and AMP-activated protein kinase (AMPK) in the liver of MASLD rats. In addition, linalool also curbed oxidative stress by increasing antioxidant enzymes and activating nuclear erythroid-2-related factor 2 (Nrf-2) and its downstream target genes involved in antioxidant properties. CONCLUSION Therefore, this study concludes that linalool attenuates lipid accumulation in the liver by inhibiting de novo lipogenesis, promoting fatty acid oxidation, and attenuating oxidative stress by regulating Sirt1/Akt/PPRA-α/AMPK and Nrf-2/ HO-1 signaling pathways.

Cardioprotective action of Amaranthus viridis methanolic extract and its isolated compound Kaempferol through mitigating lipotoxicity, oxidative stress and inflammation in the heart. 3 Biotech 2023; 13:317. [PMID: 37637004 PMCID: PMC10457263 DOI: 10.1007/s13205-023-03680-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Accepted: 06/21/2023] [Indexed: 08/29/2023] Open
Abstract
The current study was designed to evaluate the cardio-protective efficacy of Amaranthus viridis L. methanolic extract (AVME) and kaempferol, which was isolated from AVME in isoproterenol (ISO)-induced cardiotoxicity in rats. The rats were pre-treated with AVME (250 mg/kg body weight) and kaempferol (50 mg/kg BW) for 30 days, respectively, and then administered with ISO (20 mg/100 g body weight) on the 31st and 32nd days. We assessed the protective effects of AVME and kaempferol against ISO-induced cardiotoxicity, oxidative stress, and inflammation. The study revealed that supplementation with AVME and kaempferol significantly attenuated cardiac lipotoxicity by reducing cholesterol and triglyceride levels and simultaneously increasing the levels of high-density lipoproteins. In addition, AVME and kaempferol suppressed oxidative stress by enhancing the activities of superoxide dismutase, catalase, and glutathione peroxidase in the heart. Further, they ameliorated cardiac inflammation by mitigating the production of pro-inflammatory cytokines (tumor necrosis factor-alpha, interleukin-6, and interleukin-1β). Hence, the study results and histopathological analysis emphasized that AVME and kaempferol could be prospective prophylactic agents against ISO-induced cardiotoxicity and may be considered nutraceuticals in the prevention of cardiovascular disorders.
