Trehalose-induced SIRT1/AMPK activation regulates SREBP-1c/PPAR-α to alleviate lipid accumulation in aged liver.

Aging is associated with a disturbance in the regulation of the metabolic function of the liver, which increases the risk of liver and systemic diseases. Trehalose, a natural disaccharide, has been identified to reduce dyslipidemia, hepatic steatosis, and glucose intolerance. However, the roles of trehalose on lipid metabolism in aged liver are unclear which was investigated in this study.

Effect of trehalose on miR-132 and SIRT1 in the hippocampus of aged rats.

Aging causes substantial molecular to morphological changes in the brain. The brain cells are more susceptible towards oxidative damage due to impaired antioxidant defense system. Sirtuin1 (SIRT1) is a crucial cellular survival protein, which its gene has been identified as a direct target of microRNA 132 (miR-132).

Validity and reliability of safety behaviors questionnaire for Persian adults who stutter: A cultural perspective.

Introduction: Adults who stutter (AWS) are reported to have higher social anxiety compared to those who do not stutter. Previous studies have suggested that safety behaviors, which are cognitive or behavioral strategies used by people with anxiety to prevent negative consequences, are important factors in maintaining anxiety. However, the frequency and types of such behaviors might vary in different cultures.

Trehalose Attenuates Learning and Memory Impairments in Aged Rats via Overexpression of miR-181c.

MicroRNAs have been recognized as important regulators of the aging process. Trehalose, a natural disaccharide, displays protective effects against neuronal impairment through several mechanisms. However, little is known about the interactive effects of aging and trehalose on behavioral function and underlying miRNA expression patterns in the hippocampus of young and old rats.

Improving SIRT1 by trehalose supplementation reduces oxidative stress, inflammation, and histopathological scores in the kidney of aged rats.

The aging process leads to progressive loss of kidney function. Sirtuin1 (SIRT1) exerts renoprotective effects by conferring resistance to cellular stresses. Trehalose potentially displayed various beneficial effects to promote health span.
