Abstract
Hormones have been considered as key factors involved in the maintenance of the redox status of the body. We are making considerable progress in understanding interactions between the endocrine system, redox status, and oxidative stress with the dynamics of life, which encompasses fertilization, development, growth, aging, and various pathophysiological states. One of the reasons for changes in redox states of vertebrates leading to oxidative stress scenario is the disruption of the endocrine system. Comprehending the dynamics of hormonal status to redox state and oxidative stress in living systems is challenging. It is more difficult to come to a unifying conclusion when some hormones exhibit oxidant properties while others have antioxidant features. There is a very limited approach to correlate alteration in titers of hormones with redox status and oxidative stress with growth, development, aging, and pathophysiological stress. The situation is further complicated when considering various tissues and sexes in vertebrates. This chapter discusses the beneficial impacts of hormones with antioxidative properties, such as melatonin, glucagon, insulin, estrogens, and progesterone, which protect cells from oxidative damage and reduce pathophysiological effects. Additionally, we discuss the protective effects of antioxidants like vitamins A, E, and C, curcumin, tempol, N-acetyl cysteine, α-lipoic acid, date palm pollen extract, resveratrol, and flavonoids on oxidative stress triggered by hormones such as aldosterone, glucocorticoids, thyroid hormones, and catecholamines. Inflammation, pathophysiology, and the aging process can all be controlled by understanding how antioxidants and hormones operate together to maintain cellular redox status. Identifying the hormonal changes and the action of antioxidants may help in developing new therapeutic strategies for hormonal imbalance-related disorders.

Abstract
BACKGROUND In contrast to free radicals, the first line of protection is assumed to be vitamin E and selenium. The present protocol was designed to assess the roles of vitamin E and/or a selenium-rich diet that affected the blood iron and copper concentrations, liver tissue antioxidant and lipid peroxidation, and gene expression linked to antioxidants in the liver tissue of broilers. The young birds were classified according to the dietary supplement into four groups; control, vitamin E (100 mg Vitamin/kg diet), selenium (0.3 mg sodium selenite/kg diet), and vitamin E pulse selenium (100 mg vitamin/kg diet with 0.3 mg sodium selenite/kg diet) group. RESULTS The results of this experiment suggested that the addition of vitamin E with selenium in the broiler diet significantly increased (P ≤ 0.05) serum iron when compared with the other groups and serum copper when compared with the vitamin E group. Moreover, the supplements (vitamin E or vitamin E with selenium) positively affected the enzymatic activity of the antioxidant-related enzymes with decreased malondialdehyde (MDA),which represents lipid peroxidation in broiler liver tissue. Moreover, the two supplements significantly upregulated genes expression related to antioxidants. CONCLUSION Therefore, vitamin E and/or selenium can not only act as exogenous antioxidants to prevent oxidative damage by scavenging free radicals and superoxide, but also act as gene regulators, regulating the expression of endogenous antioxidant enzymes.

Abstract
Caloric restriction (CR) has been shown to extend the lifespan of many species. Research to identify compounds that imitate the results of CR has shown extensions of both lifespan and healthspan via different mechanisms. For example, mechanistic target of rapamycin (mTOR) inhibitors such as rapamycin, phenols, and flavonoids show antioxidant characteristics, while spermidine induces autophagy. Herein, we summarize research progress and proposed mechanisms for the most well-known compounds showing lifespan-extending potential for anti-aging characteristics.

Abstract
COVID-19 pandemic has affected more than 200 countries and 1.3 million individuals have deceased within eleven months. Intense research on COVID-19 occurrence and prevalence enable us to understand that comorbidities play a crucial role in spread and severity of SARS-CoV-2 infection. Chronic kidney disease, diabetes, respiratory diseases and hypertension are among the various morbidities that are prevalent in symptomatic COVID-19 patients. However, the effect of altered thyroid-driven disorders cannot be ignored. Since thyroid hormone critically coordinate and regulate the major metabolism and biochemical pathways, this review is on the potential role of prevailing thyroid disorders in SARS-CoV-2 infection. Direct link of thyroid hormone with several disorders such as diabetes, vitamin D deficiency, obesity, kidney and liver disorders etc. suggests that the prevailing thyroid conditions may affect SARS-CoV-2 infection. Further, we discuss the oxidative stress-induced aging is associated with the degree of SARS-CoV-2 infection. Importantly, ACE2 protein which facilitates the host-cell entry of SARS-CoV-2 using the spike protein, are highly expressed in individuals with abnormal level of thyroid hormone. Altogether, we report that the malfunction of thyroid hormone synthesis may aggravate SARS-CoV-2 infection and thus monitoring the thyroid hormone may help in understanding the pathogenesis of COVID-19.

Abstract
OBJECTIVES The objective of this study was to evaluate the effect of vitamin E on the oxidative stress parameters and antioxidant defense enzymes in the heart and aorta of 6-n-propylthiouracil (PTU)-induced hypothyroid rats. METHODS The animals were divided into 4 experimental groups: Group 1 (Euthyroid) received tap water, Group 2 (Hypothyroid) received 0.05 % of PTU in dissolved in their drinking water, Group 3 (PTU+Vit E) hypothyroid rats treated with vitamin E, and Group 4 (Euthyroid+Vit E). Vitamin E was injected daily (20 mg/kg) to groups 3 and 4 via daily gavage for 6 weeks. Malondialdehyde (MDA) levels, total thiol levels, and the activities of Cu, Zn-superoxide dismutase (SOD) and catalase (CAT) were evaluated in the aortic and cardiac tissues. RESULTS A significant decrease of thyroxine (T4) serum levels confirmed hypothyroidism in rats, which received PTU. The MDA level increased and total thiol level decreased in the hypothyroid group compared to control group (p<0.001). Th e activities of SOD and CAT significantly decreased in the hypothyroid rats in comparison to the control. Vitamin E treatment resulted in increased levels of total thiol, SOD, and CAT within aortic and cardiac tissues and decreased levels of MDA in comparison with the hypothyroid group (p<0.01-p<0.001). CONCLUSIONS PTU-induced hypothyroidism resulted in oxidative stress. Chronic administration of vitamin E to hypothyroid rats decreased the oxidative stress markers in the aortic and cardiac tissues.

Abstract
Thyroid hormones have important role in metabolism and impairment of glucose metabolism and insulin secretion has been shown in hypothyroid rats but the exact mechanisms for this defect are poorly understood. The aim of this study was to investigate the effect of hypothyroidism on oxidative stress parameters, insulin secretory pathway and histomorphometric changes of pancreas. In the isolated islets of the control and methimazole -treated hypothyroid insulin secretion and content, ATP production, Glucokinase, and hexokinase specific activity and kATP and L-type channels sensitivity were assayed. In order to determine oxidative stress parameters, antioxidant enzymes and lipid peroxidation were measured in pancreatic homogenates. Histomorphometric changes and histochemistry of the islet in both groups were compared. Results showed that plasma glucose and insulin concentration and their area under the curve during IPGTT in hypothyroid group were respectively higher and lower than the controls. In the hypothyroid islets, glucose stimulated insulin secretion, ATP production, hexokinase and glucokinase activities were decreased. Hypothyroid induced a significant increased lipid peroxidation, and decreased the antioxidant enzyme activity. Compared with the control group, insulin antibody positivity, the total volume of the pancreas, islets, and the total number as well as the mean volume of the beta cells were also significantly decreased in the hypothyroid group. These findings indicate that oxidative stress produced under hypothyroidism could have a role in progression of pancreatic β-cell dysfunction, reduced beta cell mass and decreased glucokinase activity, impairing glucose tolerance and insulin secretion.

Abstract
INTRODUCTION Cellular antioxidant signaling can be altered either by thyroid disturbances or by selenium status. AIMS To investigate whether or not dietary diphenyl diselenide can modify the expression of genes of antioxidant enzymes and endpoint markers of oxidative stress under hypothyroid conditions. METHODS Female rats were rendered hypothyroid by continuous exposure to methimazole (MTZ; 20 mg/100 ml in the drinking water) for 3 months. Concomitantly, MTZ-treated rats were either fed or not with a diet containing diphenyl diselenide (5 ppm). mRNA levels of antioxidant enzymes and antioxidant/oxidant status were determined in the cerebral cortex, hippocampus and striatum. RESULTS Hypothyroidism caused a marked upregulation in mRNA expression of catalase, superoxide dismutase (SOD-1, SOD-3), glutathione peroxidase (GPx-1, GPx-4) and thioredoxin reductase (TrxR-1) in brain structures. SOD-2 was increased in the cortex and striatum, while TrxR-2 increased in the cerebral cortex. The increase in mRNA expression of antioxidant enzymes was positively correlated with the Nrf-2 transcription in the cortex and hippocampus. Hypothyroidism caused oxidative stress, namely an increase in lipid peroxidation and reactive oxygen species levels in the hippocampus and striatum, and a decrease in nonprotein thiols in the cerebral cortex. Diphenyl diselenide was effective in reducing brain oxidative stress and normalizing most of the changes observed in gene expression of antioxidant enzymes. CONCLUSION The present work corroborates and extends that hypothyroidism disrupts antioxidant enzyme gene expression and causes oxidative stress in the brain. Furthermore, diphenyl diselenide may be considered a promising molecule to counteract these effects in a hypothyroidism state.

Abstract
Background Hypothyroidism is a chronic condition of endocrine disorder and its precise molecular mechanism remains obscure. In spite of certain efficacy of thyroid hormone replacement therapy in treating hypothyroidism, it often results in other side effects because of its over-replacement, so it is still urgent to discover new modes of treatment for hypothyroidism. Sini decoction (SND) is a well-known formula of Traditional Chinese Medicine (TCM) and is considered as efficient agents against hypothyroidism. However, its holistic effect assessment and mechanistic understanding are still lacking due to its complex components. Methodology/Principal Findings A urinary metabonomic method based on ultra performance liquid chromatography coupled to mass spectrometry was employed to explore global metabolic characters of hypothyroidism. Three typical hypothyroidism models (methimazole-, propylthiouracil- and thyroidectomy-induced hypothyroidism) were applied to elucidate the molecular mechanism of hypothyroidism. 17, 21, 19 potential biomarkers were identified with these three hypothyroidism models respectively, primarily involved in energy metabolism, amino acid metabolism, sphingolipid metabolism and purine metabolism. In order to avert the interference of drug interaction between the antithyroid drugs and SND, the thyroidectomy-induced hypothyroidism model was further used to systematically assess the therapeutic efficacy of SND on hypothyroidism. A time-dependent recovery tendency was observed in SND-treated group from the beginning of model to the end of treatment, suggesting that SND exerted a recovery effect on hypothyroidism in a time-dependent manner through partially regulating the perturbed metabolic pathways. Conclusions/Significance Our results showed that the metabonomic approach is instrumental to understand the pathophysiology of hypothyroidism and offers a valuable tool for systematically studying the therapeutic effects of SND on hypothyroidism.

Abstract
This study is designed to investigate the effect of ischemia post-conditioning on IR-induced skeletal muscle injury in limbs of experimental rabbits. Rabbits are randomized to one of the following three groups: sham control, ischemic reperfusion, ischemic postconditioning. The lipid peroxidation level, antioxidant enzymes activities, skeletal muscle mammalian target of rapamycin (mTOR), Bax, Bcl-2 proteins expression and Bcl-2/Bax, and HIF-1α/β-actin mRNA, interleukin-6 (IL-6)/β-actin mRNA and caveolin-3/β-actin mRNA expression were tested in the current study. The results suggested that ischemic postconditioning might decrease lipid peroxidation level, lactic dehydrogenase (LDH), creatine kinase (CK) activities, Bcl-2 proteins expression and Bcl-2/Bax, HIF-1α/β-actin mRNA expression and increase skeletal muscle antioxidant enzymes activities, Bax protein expression and IL-6/β-actin mRNA and caveolin-3/β-actin mRNA expression. These indicated that protective effect of ischemic postconditioning against IR-induced skeletal muscle injury involve into a complex molecular mechanism. Our research results may offer a theoretical guidance for therapy of related clinical diseases.

Abstract
In the present study, regulatory role of vitamin E and curcumin on antioxidant gene (AOG) expression in hypothyroid rat liver is reported. Adult male rats were rendered hypothyroid by administration of 0.05 % 6-propyl-thiouracil in their drinking water, while vitamin E (200 mg/kg body weight) and curcumin (30 mg/kg body weight) were supplemented orally for 30 days. Expression of antioxidant genes (Cu/Zn-superoxide dismutase; SOD1, Mn superoxide dismutase; SOD2, catalase; CAT, glutathione peroxidase; GPx1 and glutathione reductase; GR) was evaluated using RT-PCR and Western blot analyses. The activities of antioxidant enzymes were measured in mitochondrial fraction (MF) and post-mitochondrial fraction (PMF) of rat liver. In addition measurement of glutathione redox status was also carried out in both the fractions. The enhanced transcripts of CAT, GPx1 and GR in hypothyroid rat liver were alleviated by administration of vitamin E and curcumin. Elevated levels of translated product of all AOGs in hypothyroid group were remained unchanged after antioxidant administration. However, enhanced SOD1, GPx1 and decreased GR activities in PMF were normalized by vitamin E and curcumin. Similarly the increased SOD2, GPx1 and decreased CAT activities in MF were also normalized by vitamin E and curcumin supplementation. Administration of vitamin E and curcumin enhanced mitochondrial GSH level; whereas the enhanced GSH level in PMF of hypothyroid rats was alleviated by vitamin E. Thus it can be concluded that besides the antioxidant role of vitamin E and curcumin, they also regulate hepatic antioxidant gene expression in hypothyroid rats.
