As an example, Liu and co-workers designed a Fe 2+ -contained and PEG-modified nanocatalyst reacting with overexpressed H 2 O 2 to generate sufficient OH, which is able to kill tumor cells ( 2 nanoparticles encapsulated with Cu-ferrocene for oxidating GSH, named CCF ( 2+ , which released from decomposed CCF in an acidic environment, triggered GSH exhaustion (Figure 5A) and Cu + -mediated Fenton-like reaction, avoiding the potential OH elimination
Notably, in vitro experiments have established ferroptosis as a key mechanism for TMAO-mediated renal tubular epithelial cell death (Ge et al., 2024)
In contrast to bariatric surgery, which addresses root causes and delivers lasting results, GLP-1 drugs provide only temporary solutions, potentially leading to medication reliance
Current research has found that inducing peptides to form multimers and using multifunctional fusion peptides can improve the delivery efficiency of CPPs to some extent
GHK-Cu is primarily investigated for its role in: Regulation of gene expression Promotion of collagen synthesis Activation of fibroblasts Extracellular matrix remodeling Protection against oxidative cellular stress Thymosin Beta-4 is primarily studied for its involvement in: Cell migration Angiogenesis Organization of the actin cytoskeleton Tissue remodeling Regeneration following experimental injury For this reason, researchers frequently use this combination to investigate the complex biological processes involved in skin and soft tissue regeneration
