PURPOSE: Diabetes mellitus (DM) is an important factor in intervertebral disc degeneration (IDD). Apoptosis of cartilage endplate (CEP) cells is one of the initiators of IDD. However, the effects of high glucose on CEP cells are still unknown. Therefore, we conducted the present study to evaluate the effects of high glucose on CEP cells and to identify the mechanisms of those effects. METHODS: Rat CEP cells were isolated and cultured in 10% foetal bovine serum (FBS, normal control) or high-glucose medium (10% FBS + 0...

BACKGROUND: Dextran sulfate sodium (DSS)-induced colitis is the most widely used model that resembles ulcerative colitis (UC) in human with challenging chronic mechanistic oxidative stress-inflammatory/immunological cascades. In models of acute colitis, reduction of oxidative stress and inflammatory burdens beside manipulation of many transcriptional factors were achieved by metformin or alpha-lipoic acid (α-LA). Currently, in vivo DSS-induced chronic colitis was conducted and the possible therapeutic roles of metformin and/or α-LA were explored...

PURPOSE OF REVIEW: Multiple sclerosis (MS) is an immune-mediated disorder that affects the central nervous system (CNS), often first affecting people in early adulthood. Although most MS patients have a relapsing-remitting course (RRMS) at disease onset, a substantial proportion later develop chronic progression, termed secondary progressive MS (SPMS). Approximately 10% of MS patients experience chronic progression from disease onset, termed primary progressive multiple sclerosis (PPMS)...

Hepatocellular carcinoma is the most frequent primary liver cancer worldwide. The use of antioxidants as cancer prevention and treatment agents has become a focus of research in recent years due to their limited adverse effects. Alpha lipoic acid (ɑ-LA) is synthesized in the liver and is considered a naturally occurring antioxidant. In this study, a total of 4446 differentially expressed genes (2097 down-regulated and 2349 up-regulated) were identified via RNA-Seq in HepG2 cells after exposure to α-LA for 24 hrs...

OBJECTIVE: Migraine as a disabling neurovascular disease affects 6% of men and 18% of women worldwide. The deficiency of many nutrients including magnesium, niacin, riboflavin, cobalamin, coenzymes Q10, carnitine, α-lipoic acid and vitamin D is associated with migraine. Some researchers postulate that mitochondrial dysfunction and impaired antioxidant status can cause migraine. Also increase in homocysteine level can lead to migraine attacks; therefore, some Nutraceuticals play a vital role in migraine prevention...

BACKGROUND: In multiple sclerosis (MS), neurodegeneration is the main reason for chronic disability. Alpha-lipoic acid (LA) is a naturally occurring antioxidant which has recently been demonstrated to reduce the rate of brain atrophy in progressive MS. However, it remains uncertain if it is also beneficial in the early, more inflammatory-driven phases. As clinical studies are costly and time consuming, optic neuritis (ON) is often used for investigating neuroprotective or regenerative therapeutics...

Little is known about the role of tumor necrosis factor-alpha (TNF-α), plasminogen activator inhibitor-1 (PAI-1), and inducible nitric oxide synthase (iNOS) in the gastric ulcer and the effect of alpha lipoic acid (ALA) in their modulation. Hence, this experimental study was designed to assess the possible protective effect of ALA against indomethacin (IND)-induced gastric ulcer in rats, as well as to determine the possible underlying mechanisms with a special focus on TNF-α, PAI-1, and iNOS. Adult male rats (n = 28) were divided into four equal groups: the control group received distilled water, the vehicle group received 0...

Limb ischemia reperfusion (I/R) injury is associated with serious local and systemic effects. Reperfusion may augment tissue injury in excess of that produced by ischemia alone. The hippocampus has been reported to be vulnerable to I/R injury. Alpha lipoic acid (ALA) is an endogenous antioxidant with a powerful antioxidative, anti-inflammatory, and antiapoptotic properties. We studied the probable restorative effect of ALA on limb I/R-induced structural damage of rat hippocampus. Forty adult male albino rats were divided equally into four groups: group I (sham); group II (I/R-1 day) has undergone bilateral femoral arteries occlusion (3 h), then reperfusion for 1 day; group III (I/R-7 days) has undergone reperfusion for seven days; group IV (I/R-ALA) has undergone I/R as group III and received an intraperitoneal injection of ALA (100 mg/kg) for 7 days...

Alpha-lipoic Acid(ALA), an endogenous short-chain fatty acid, has been found inducing a protective effect against ischemia and reperfusion(I/R) injury. Recently, mTOR signaling pathway has been proved to involve in the mechanism of I/R injury. In our previous study, we determined that ALA could protect cerebral endothelial cells against I/R injury via mTOR signaling pathway. However, whether ALA can protect against brain I/R injury in vivo and its mechanisms is uncertain. In this study, we try to explore if the ALA treatment can protect against brain I/R injury and confirm the relationship between ALA and mTOR signaling pathway...

PURPOSE: Alpha-lipoic acid (ALA), widely known as an antioxidant, modifies also serum levels of angiogenic factors in type 2 diabetic patients. These pharmacological activities may influence the status of the cardiovascular system. Taking into consideration that diabetes is related to the increased cardiovascular risk we investigated several effects of ALA on angiogenic factors in the myocardium and in the aortal wall using a rat model of type 2 diabetes. METHODS: Diabetes was induced in Wistar rats by a fat-rich diet and by intraperitoneal injection of a small dose of streptozotocin (30 mg/kg)...

Hypoxia is associated with an increased systemic and cerebral formation of free radicals and associated reactants that may be linked to impaired cerebral vascular function a neurological sequela. To what extent oral antioxidants prophylaxis impacts cerebrovascular function in humans throughout the course of acclimatization to the hypoxia of terrestrial high-altitude has not been examined. Thus, the purpose of the current study was to examine the influence of orally ingested antioxidants at clinically relevant doses (vitamin C, E, and alpha-lipoic acid) on cerebrovascular regulation at sea-level (344 m; n = 12; female n = 2 participants), and at high altitude (5050 m; n = 9; female n = 2), in a randomized, placebo-controlled, and double-blinded crossover design...
