CASIN exerts anti-aging effects through RPL4 on the skin of naturally aging mice

5 months 3 weeks ago
Skin aging has been associated with the onset of various skin issues, and recent studies have identified an increase in Cdc42 activity in naturally aging mice. While previous literature has suggested that CASIN, a specific inhibitor of Cdc42 activity, may possess anti-aging properties, its specific effects on the epidermis and dermis, as well as the underlying mechanisms in naturally aging mice, remain unclear. Our study revealed that CASIN demonstrated the ability to increase epidermal and...

Identification of AS1842856 as a novel small-molecule GSK3α/β inhibitor against Tauopathy by accelerating GSK3α/β exocytosis

5 months 3 weeks ago
Glycogen synthase kinase-3α/β (GSK3α/β) is a critical kinase for Tau hyperphosphorylation which contributes to neurodegeneration. Despite the termination of clinical trials for GSK3α/β inhibitors in Alzheimer's disease (AD) treatment, there is a pressing need for novel therapeutic strategies targeting GSK3α/β. Here, we identified the compound AS1842856 (AS), a specific forkhead box protein O1 (FOXO1) inhibitor, reduced intracellular GSK3α/β content in a FOXO1-independent manner. Specifically, AS...

Glial <em>swip-10</em> controls systemic mitochondrial function, oxidative stress, and neuronal viability via copper ion homeostasis

5 months 3 weeks ago
Cuprous copper [Cu(I)] is an essential cofactor for enzymes that support many fundamental cellular functions including mitochondrial respiration and suppression of oxidative stress. Neurons are particularly reliant on mitochondrial production of ATP, with many neurodegenerative diseases, including Parkinson's disease, associated with diminished mitochondrial function. The gene MBLAC1 encodes a ribonuclease that targets pre-mRNA of replication-dependent histones, proteins recently found in yeast...

Structural basis of CDNF interaction with the UPR regulator GRP78

5 months 3 weeks ago
Cerebral dopamine neurotrophic factor (CDNF) is an unconventional neurotrophic factor that is a disease-modifying drug candidate for Parkinson's disease. CDNF has pleiotropic protective effects on stressed cells, but its mechanism of action remains incompletely understood. Here, we use state-of-the-art advanced structural techniques to resolve the structural basis of CDNF interaction with GRP78, the master regulator of the unfolded protein response (UPR) pathway. Subsequent binding studies...
