Middle-aged mice treated with GHK-Cu peptide administered intraperitoneally or intranasally show behavioral rescue but divergent hippocampal aging programs

Abstract Age-related cognitive decline (ARCD) is driven by conserved biological mechanisms of aging, yet no gerotherapeutic directly targets these processes in the brain.

Study · 2026

The Laccase-like Property of GHK-Cu and Its Applications in Colorimetric Sensing of Phenolic Compounds

Laccase plays an important role in the detection and degradation of phenolic compounds, but it is limited by its cost and stability. In this study, the laccase-like property of copper peptide (GHK-Cu) has been revealed.

The GHK-Cu delays aging in Caenorhabditis elegans via coordinated regulation of mitochondrial function and activation of DAF-16/SKN-1 pathways

Aging is a complex biological process characterized by progressive functional decline across tissues and increased susceptibility to age-related diseases, with oxidative stress being a key contributing factor.

Glycyl-L-histidyl-L-lysine-Cu2<sup>+</sup> (GHK-Cu) Attenuates CuSO<sub>4</sub> or LPS induced-inflammation in Zebrafish larvae model

Inflammation serves as a basic defense mechanism against both internal and external threats, while the unresolved or excessive inflammation can lead to irreversible tissue damage.

animal · 2026

Middle-aged mice treated with GHK-Cu peptide administered intraperitoneally or intranasally show behavioral rescue but divergent hippocampal aging programs

Age-related cognitive decline (ARCD) is driven by conserved biological mechanisms of aging, yet no gerotherapeutic directly targets these processes in the brain. Glycyl-L-histidyl-L-lysine complexed with copper (GHK-Cu) is an endogenous peptide with regenerative and anti-inflammatory properties that declines with age.

Microenvironment-responsive injectable dynamic hydrogel for sequential antioxidant and tissue regeneration therapy of radiation-induced skin injury

Radiotherapy is essential for cancer treatment, yet radiation-induced skin injury (RISI) remains a major clinical challenge due to reactive oxygen species (ROS) accumulation, metabolic dysregulation, and the limited efficacy of single-modality therapies in modulating the oxidative-inflammatory microenvironment.
