TL;DR

PSTX incubation blocked TRPM2-mediated Ca2+ signaling, reducing AMD-induced mitochondrial oxidant injury and cell death and PSTX, a new TRPM2 antagonist, may be utilized to treat oxidative stress and aberrant Ca2+ influx induced by AMD.

The Venom of Tarantula Cubensis (Theranekron) Reduces Apoptosis and Mitochondrial Oxidative Toxicity Caused by NaIO3–Induced Age-Related Macular Degeneration in Human Retinal Pigment Epithelium Cells

Excessive generations of apoptosis and oxygen free radicals (OFRs) are two main common reasons of age-related macular degeneration (AMD). A homeopathic preparation of the Tarantula Cubensis spider venom is Theranekron (TNE). The antiapoptotic and antioxidant actions of TNE were indicated in different disease models exc...

Icariside II protects against neuronal injury by modulating PI3K/AKT-dependent mitochondrial dynamics and apoptosis in Alzheimer’s disease models

Introduction Icariside II (ICS II), a major bioactive flavonoid metabolite from Epimedium, has been reported to exert neuroprotective effects, but its role in regulating mitochondrial dysfunction-related neuronal injury in Alzheimer’s disease (AD) has not been fully clarified. Methods In this study, we administered ICS...
