Abstract
Many industrial chemicals have been reported as anti-androgenic substances. Exposure to these substances represents a potential risk to human health, particularly to the development of reproductive organs such as embryonic external genitalia (eExG). Currently, there is a need for more assay systems that can elucidate the toxicological actions and mechanisms of endocrine disrupting chemicals (EDCs). In this study, we show that the eExG slice culture assay is useful for the evaluation of the differing modes of action of EDCs on urethra formation. We assessed the possible endocrine disrupting activity of three chemicals with reported anti-androgenic function, diazinon (DZN), dibutyl phthalate (DBP) and fenitrothion (FNT) on eExG slices. Exposure to FNT, but not DZN and DBP, induced defects of androgen-induced urethral masculinization and reduced expression of the androgen-target gene Mafb. Live imaging analyses showed that FNT treatment inhibited androgen-dependent MAFB induction within 12 hours. Furthermore, FNT-treated tissue slices showed reduced expression of the androgen receptor (AR). These results indicate that FNT disrupts androgen signaling by reduction of AR expression during androgen-induced eExG masculinization. The current study thus highlights the importance of animal models which allow for the effective assessment of tissue-specific endocrine-disrupting activity to further reveal the etiology of chemical-induced congenital anomalies.

Resveratrol alleviates cardiac apoptosis following exposure to fenitrothion by modulating the sirtuin1/c-Jun N-terminal kinases/p53 pathway through pro-oxidant and inflammatory response improvements: In vivo and in silico studies. Life Sci 2022; 290:120265.

Abstract
Fenitrothion (FNT), a commonly used organophosphate, can cause oxidative damage and apoptosis on various organs. However, the underlying mechanisms for FNT-induced cardiotoxicity did not formally report. Here, we have evaluated the possible ameliorative roles of resveratrol (RSV) against FNT-induced cardiac apoptosis in male rats through the sirtuin1 (SIRT1)/c-Jun N-terminal kinase (c-JNK)/p53 pathway concerning pro-oxidant and inflammatory cytokines. Forty-eight male rats were equally grouped into control, RSV (20 mg/kg), 5-FNT (5 mg/kg), 10-FNT (10 mg/kg), 20-FNT (20 mg/kg), 5-FNT-RSV, 10-FNT-RSV, and 20-FNT-RSV where all doses administrated by gavage for four weeks. The present findings demonstrated that RSV markedly diminished the level of hyperlipidemia and elevation in lactate dehydrogenase (LDH), total creatine kinase (CK-T), and troponin T (TnT) levels following FNT intoxication. Furthermore, RSV significantly reduced FNT-induced cardiac oxidative injury by reducing malondialdehyde (MDA) level and improving the levels of glutathione (GSH), glutathione reductase (GR), superoxide dismutase (SOD), catalase (CAT), and acetylcholinesterase (AchE). Also, the levels of interleukin-1β (IL1β,), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were significantly attenuated in the co-treated groups. Moreover, RSV alleviated the histopathological changes promoted by FNT and repaired the transcript levels of SIRT1, c-JNK, and caspase-9/3 along with p53 immunoreactivity. In silico study revealed that the free binding energies of RSV complexes with protein and DNA sequences of SIRT1 were lower than docked complexes of FNT. Therefore, RSV reserved myocardial injury-induced apoptosis following exposure to FNT by modulating the SIRT1/c-JNK/p53 pathway through cellular redox status and inflammatory response improvements.

Abstract
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by loss of memory and other cognitive abilities. AD is associated with aggregation of amyloid-β (Aβ) deposited in the hippocampal brain region. Our previous work has shown that tocotrienol rich fraction (TRF) supplementation was able to attenuate the blood oxidative status, improve behavior, and reduce fibrillary-type Aβ deposition in the hippocampus of an AD mouse model. In the present study, we investigate the effect of 6 months of TRF supplementation on transcriptome profile in the hippocampus of APPswe/PS1dE9 double transgenic mice. TRF supplementation can alleviate AD conditions by modulating several important genes in AD. Moreover, TRF supplementation attenuated the affected biological process and pathways that were upregulated in the AD mouse model. Our findings indicate that TRF supplementation can modulate hippocampal gene expression as well as biological processes that can potentially delay the progression of AD.

Abstract
Monosodium glutamate (MSG) is widely used in food preparation industry and has been consumed regularly. Previous studies had reported on effects of MSG when given at extremely high dosages, the results are not applicable to human equivalent intake. Therefore, the present study aimed to evaluate the effect of MSG on sperm quality and changes in reproductive organs of adult male rats when taken at average human daily intake (ADI). Twenty-four adult male rats were randomly assigned into three groups; NC (Normal control), MSG60 and MSG120 where MSG was given orally at 60 mg/kg and 120 mg/kg to each respective group. All treatments were conducted for 28 consecutive days. MSG at estimated ADI of 120 mg/kg body weight resulted in a significant drop in sperm quality (p < 0.05) when compared to both control and MSG60 groups. A significant decrease in the weight of reproductive organs was also apparent (p < 0.05). Moreover, oxidative status evaluation showed that treatment of MSG induces oxidative stress in the testis, more severely at a dose of 120 mg/kg body weight. These findings are supported by alterations in the observed histology of reproductive organs. This study shows that an intake dose of 120 mg/kg body weight MSG could cause significant damage to the reproductive system. Abbreviations: MSG: Monosodium glutamate; ADI: average daily intake; PUFA: polyunsaturated fatty acid; FSH: follicle stimulating hormone; LH: luteinizing hormone; TCA: tricarbocylic acid; PF: prostatic fluid.

Abstract
Fenitrothion is widely used organophosphate pesticide in agriculture and health programs, but besides, it causes several toxic effects. The present study was designed to evaluate the possible protective effects of selenium (0.5mg/kg b.w.) and vitamin C (100mg/kg b.w) on altered haematological, biochemical and oxidative stress parameters in the blood of rats orally treated with fenitrothion (20mg/kg b.w) for 30days. Fenitrothion caused changes in body weight, food and water intake, and some haematological and biochemical parameters. Fenitrothion altered the glutathione redox status (GSH and GSSG) and decreased activity of antioxidant enzymes (GSH-Px, GST, SOD and CAT), leading to a lipid peroxidation. Selenium and vitamin C, by improving the activity of antioxidants, reduced oxidative stress and a lipid peroxidation, maintaining the values of examined parameters to optimal levels. Therefore, selenium and vitamin C could be useful in providing protection of exposed non-target organisms including people from fenitrothion.
