Identification of the role of autophagy-related TNFSF10/ hsa-let-7a-5p axis in vitiligo development and potential herbs exploring based on a bioinformatics analysis. Heliyon 2023; 9:e23220. [PMID: 38149194 PMCID: PMC10750083 DOI: 10.1016/j.heliyon.2023.e23220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 11/28/2023] [Accepted: 11/29/2023] [Indexed: 12/28/2023] Open
Abstract
Background Vitiligo is a common clinical disorder caused by the destruction of epidermal melanocytes, which is often associated with autoimmune mechanisms. Autophagy plays a crucial role in maintaining cellular homeostasis and exhibits close associations with various autoimmune disorders. While dysautophagy of melanocytes is associated with vitiligo pathogenesis, there is a lack of studies on autophagy-related genes (ARGs) in blood samples from individuals with vitiligo. Methods Blood samples from individuals with vitiligo and healthy controls were compared to identify differentially expressed genes (DEGs), which were subsequently subjected to further analysis. Then, miRNAs correlated with core genes were predicted by five distinct online tools, and those miRNAs that appeared in three or more tools at the same time were chosen for further enrichment analysis. Furthermore, in vitro experiments of targeting core genes were conducted. Results The results showed that there were a total of 30 ARGs among DEGs, with 13 up-regulated genes and 17 down-regulated genes. Based on the functional enrichment analysis of DEGs and projected miRNAs, we hypothesized that autophagy and apoptosis may synergistically contribute to the progression of vitiligo, with the TNFSF10/hsa-let-7a-5p axis potentially playing an important role that should not be ignored. In addition, epigallocatechin-3-gallate (EGCG) was found to be the common component in BAI GUO, CHA YE, and MEI ZHOU JIN LV MEI, which were discovered to be potential in vitiligo treatment by inducing cell autophagy and apoptosis targeting TNFSF10. Conclusion It was the first time that TNFSF/hsa-let-7a-5p was discovered to be involved in the development of vitiligo through autophagy and apoptosis. Meanwhile, we observed that BAI GUO, CHA YE, and MEI ZHOU JIN LV MEI were promising to treat vitiligo by regulating autophagy and apoptosis via TNFSF10. These findings could lead to new directions for investigating the pathogenesis and therapy of vitiligo.

Abstract
Metformin is a classical drug used to treat type 2 diabetes. With the development of research on metformin, it has been found that metformin also has several advantages aside from its hypoglycemic effect, such as anti-inflammatory, anti-aging, anti-cancer, improving intestinal flora, and other effects. The prevention of inflammation is critical because chronic inflammation is associated with numerous diseases of considerable public health. Therefore, there has been growing interest in the role of metformin in treating various inflammatory conditions. However, the precise anti-inflammatory mechanisms of metformin were inconsistent in the reported studies. Thus, this review aims to summarize various currently known possible mechanisms of metformin involved in inflammatory diseases and provide references for the clinical application of metformin.

Abstract
Podocytes form a key component of the glomerular filtration barrier. Damage to podocytes is referred to as “podocyte disease.” There are many causes of podocyte injury, including primary injury, secondary injury, and gene mutations. Primary podocytosis mostly manifests as nephrotic syndrome. At present, first-line treatment is based on glucocorticoid administration combined with immunosuppressive therapy, but some patients still progress to end-stage renal disease. In Asia, especially in China, traditional Chinese medicine (TCM) still plays an important role in the treatment of kidney diseases. This study summarizes the potential mechanism of TCM and its active components in protecting podocytes, such as repairing podocyte injury, inhibiting podocyte proliferation, reducing podocyte apoptosis and excretion, maintaining podocyte skeleton structure, and upregulating podocyte-related protein expression. At the same time, the clinical efficacy of TCM in the treatment of primary podocytosis (including idiopathic membranous nephropathy, minimal change disease, and focal segmental glomerulosclerosis) is summarized to support the development of new treatment strategies for primary podocytosis.

Mutation of Beclin1 acetylation site at K414 alleviates high glucose-induced podocyte impairment in the early stage of diabetic nephropathy by inhibiting hyperactivated autophagy. Mol Biol Rep 2022; 49:3919-3926. [PMID: 35175505 DOI: 10.1007/s11033-022-07242-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 02/08/2022] [Indexed: 10/19/2022]
Abstract
BACKGROUND Our group recently reported that a mutation of the novel Beclin1 K414R acetylation site impacts the stability of Beclin1 protein, which decreases autophagy in adipocytes and further impedes adipocyte differentiation and lipolysis. This study was to explore whether Beclin1 acetylation plays a role in the early renal injury induced by high glucose and to further investigate the K414R mutation site in podocytes. METHODS Male Sprague-Dawley rats were randomized to con (control) and diabetic nephropathy (DN) groups. The DN group was induced by a single 55 mg/kg intraperitoneal injection of streptozotocin and fed a high-fat and high-sugar diet (the con group received an equal volume of the vehicle and fed a plain diet), after 3 days of induction, blood glucose levels were measured to confirm the onset of diabetes. Then, at weeks 0 and 4, the biochemical index was assayed and renal cortex tissues were harvested. MPC5 podocytes were cultured in vitro. Beclin1 (K414R)-pLVX-ZsGreen1-N1(wild-type or mutant) lentiviral plasmids were transfected into podocytes. Western blot or immunoprecipitation was used to test proteins or the acetylation levels respectively, and immunohistochemistry was used to analyze morphological changes of podocytes. Immunofluorescence was used to detect the aggregation of LC3 puncta. RESULTS The acetylation level of Beclin1 was upregulated with podocyte injury exacerbated in high glucose at 24 h and that a mutation at K414R could inhibit hyperactivated autophagy, which ameliorated podocyte impairment. CONCLUSION These findings suggest that the acetylation site at K414 is a critical molecule and drug target and that further research into this area is warranted.

Potential effect of tropical fruits Phyllanthus emblica L. for the prevention and management of type 2 diabetic complications: a systematic review of recent advances. Eur J Nutr 2021; 60:3525-3542.

Abstract
Phyllanthus emblica is a fruit widely consumed in subtropical areas, which is rich in polyphenols and other nutrients. There are increasing evidences that as a daily and nutritious fruit, it may have a positive role in controlling diabetic complications. According to the new study, its mechanisms include enhancing the functioning of insulin, reducing insulin resistance, activating the insulin-signaling pathway, protecting β-cells, scavenging free radicals, alleviating inflammatory reactions, and reducing the accumulation of advanced glycation end products. Owing to its few side effects, and low price, it should be easily accepted by patients and has potential for preventing diabetes. Taken together, Phyllanthus emblica may be an ideal fruit for controlling diabetic complications. This review highlights the latest findings of the role of Phyllanthus emblica in anti-diabetes and its complications, especially clarifies the molecular mechanism of the chemical components related to this effect, and prospects some existing problems and future research directions.
