Preclinical studies demonstrate that GT and its compounds can reduce reactive oxygen species (ROS), enhance antioxidant capacity, and alleviate aging-related issues such as memory impairments, cognitive decline, and shortened lifespan. Clinical trials corroborate the efficacy of topical GT formulations in improving skin tone, texture, and elasticity and reducing wrinkles. The present manuscript summarizes the recent update on the anti-aging potential of GT and its possible mechanisms. The literature survey suggests that GT consumption is linked to improved cognition, reduced depression levels, and activation of pathways in model organisms like C. elegans. Additionally, tea polyphenols enhance fibroblast mitophagy, boost hippocampal synaptic plasticity in rodents, and mitigate age-related cognitive decline. Moreover, EGCG exhibits anti-aging properties by reducing TNF-induced MMP-1 expression, suppressing ERK signaling, and inhibiting MEK and Src phosphorylation in human dermal fibroblasts. In the context of skin permeation and deposition, optimized transfersomal formulation (TF) incorporating EGCG and hyaluronic acid (HA) demonstrates significantly increased skin permeation and deposition of EGCG compared to plain EGCG. Furthermore, EGCG protects cardiomyocytes via the PPARγ pathway and combats age-related muscle loss through miRNA-486-5p regulation, AKT activation, and FoxO1a-mediated expression of MuRF1 and Atrogin-1. In conclusion, the regular consumption of GT holds promise for promoting physical and mental health, delaying brain and skin aging, and improving overall health by enhancing total antioxidant capacity.</p>","PeriodicalId":18548,"journal":{"name":"Mini reviews in medicinal chemistry","volume":" ","pages":"403-424"},"PeriodicalIF":3.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142391736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diabetes, characterized by chronic hyperglycemia, poses a substantial global health burden, with an increasing prevalence worldwide. Despite significant progress in our understanding of this complex metabolic disorder, optimal therapeutic strategies still remain elusive. The advent of cuproptosis, a term coined to describe copper-induced cellular cell death and its pivotal role in diabetes pathogenesis, opens new avenues for innovative interventions. Copper, an indispensable trace element, plays a pivotal role in a myriad of vital biological processes, encompassing energy production, bolstering antioxidant defenses, and altered cellular signaling. However, in the context of diabetes, this copper homeostasis is perturbed, driven by a combination of genetic predisposition, dietary patterns, and environmental factors. Excessive copper levels act as catalysts for oxidative stress, sparking intricate intracellular signaling cascades that further exacerbate metabolic dysfunction. In this review, we aim to explore the interrelationship between copper and diabetes comprehensively, shedding light on the intricate mechanisms underpinning cuproptosis. By unraveling the roles of copper transporters, copper-dependent enzymes, and cuproptotic signaling pathways, we seek to elucidate potential therapeutic strategies that harness the power of copper modulation in diabetes management.

The activation of several DNA repair mechanisms, such as Base Excision Repair (BER), DNA Mismatch Repair (MMR), and O-6- Methylguanine-DNA Methyltransferase (MGMT), is the main mechanism via which TMZ resistance develops. The zinc-finger DNA-binding enzyme poly (ADP-ribose) polymerase-1 (PARP1), which is activated by binding to DNA breaks, affects the activation of the MGMT, BER, and MMR pathway deficiency, which results in TMZ resistance in GBM.

This phenomenon plays a crucial role in enabling tumour cells to avoid apoptosis, hence facilitating the development of resistant cells against chemotherapy.
