The results demonstrate that LTA mitigates liver tissue damage and reduces the serum levels of aspartate aminotransferase and alanine aminotransferase, and liver levels of triglycerides, malondialdehyde, reactive oxygen species (ROS), tumor necrosis factor-α, interleukin-6, and interleukin-1β. However, LTA enhances the activity of ethanol-metabolizing enzymes and decreases ethanol and acetaldehyde serum levels. Mechanistically, LTA accelerates alcohol metabolism by upregulating the hepatic expression of ADH6, ALDH1B1, ALDH2, CAT, and ACSS1 mRNA and protein in AALI mice, LTA downregulates the expression of CYP2E1 mRNA and protein and promoting antioxidative activities thus reducing the accumulation of ROS.

Androgenetic alopecia (AGA) is one of the most prevalent types of nonscarring hair loss. This review summarizes the existing evidence on the relationship between AGA and various micronutrients, including vitamin B, vitamin D, vitamin A, vitamin C, iron, selenium, zinc, manganese, and copper.METHODSA literature search was conducted to identify relevant articles published between 1993 and 2023. The search identified 49 relevant articles.RESULTSThe findings suggest that deficiencies or imbalances in these micronutrients may contribute to the pathogenesis of AGA and represent modifiable risk factors for hair loss prevention and treatment. Vitamin B, vitamin D, iron, and zinc appear to play critical roles in hair growth and maintenance. Deficiencies in these micronutrients have been associated with increased risk of AGA, while supplementation with these nutrients has shown potential benefits in improving hair growth and preventing hair loss. However, the current evidence is not entirely consistent, with some studies reporting no significant associations.CONCLUSIONDeficiencies or imbalances in specific vitamins and minerals, especially vitamin B, vitamin D, Fe, Se, and Zn are involved in the pathogenesis of AGA and may represent modifiable risk factors for the treatment and prevention of this condition.","PeriodicalId":212,"journal":{"name":"Molecular Nutrition & Food Research","volume":"44 1","pages":"e2400652"},"PeriodicalIF":5.2,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142488259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the effect of maternal broccoli powder (BP) intake during lactation on insulin resistance and liver inflammation in high-fructose-diet-fed adult male offspring exposed to maternal protein restriction.METHODS AND RESULTSPregnant Wistar rats are provided normal protein (NP) or low protein (LP) diets and 0% or 0.74% BP-containing NP diets and 0% or 0.74% BP-containing LP diet during lactation.
