📚MedChemExpress Digest | #KRAS-Targeted Cancer Research The field of KRAS signaling has rapidly evolved beyond “druggability” into mutation-driven precision therapies. Early KRAS G12C inhibitors validated KRAS as a target, but also exposed key challenges including resistance, adaptive signaling, and tumor microenvironment remodeling. 🚀 New strategies are expanding the landscape: • KRAS G12D inhibitors • RAS(ON) inhibitors • Pan-RAS approaches #ASCO2026 data (e.g., #Daraxonrasib) further highlights the shift toward broader coverage and improved clinical outcomes. Beyond inhibition, emerging modalities such as protein degradation, RNA therapeutics, and synthetic lethality are reshaping intervention strategies. 🌱 The next phase focuses on overcoming resistance, expanding mutation coverage, and improving durability through tumor ecosystem remodeling.

🚀From Bench to Paper | HDAC Epigenetics Unlocks the Secret of Osimertinib Cardiotoxicity #Osimertinib, a 3rd-gen EGFR-TKI for EGFR-mutant #NSCLC, is highly effective but linked to #cardiotoxicity (↓LVEF, heart failure, fibrosis). The mechanism and in vivo model were previously unclear. 🐭🔬Researchers built a TAC mouse model and showed that osimertinib induces cell-autonomous cardiotoxicity via ERK/AKT suppression, p53-driven apoptosis, and mitochondrial dysfunction. #HDAC upregulation drives global histone deacetylation and cardiac injury–associated transcriptomic reprogramming. HDAC inhibition (#vorinostat /SAHA) protects cardiac function while maintaining or enhancing anti-tumor activity. 💡Proud to support vorinostat in this study.

🎨 Science Visuals | Rabies & Bat Exposure 🦇 A #bat bite can be so small that it leaves no obvious mark—yet it may still transmit rabies. A reported case highlighted this risk: a boy woke to find a bat lying across his face. Because no visible bite was found, #rabies post-exposure prophylaxis (#PEP) was not given. 19 days later, he developed vomiting and facial numbness and ultimately died from rabies. ⚠️ Experts emphasize that any direct contact with a bat should be evaluated by a healthcare professional immediately, even if you cannot see a bite or scratch. Summer bat activity is rising across North America 🌡️ Rabid bats are being reported in multiple regions. Don’t handle bats. Seek care immediately after exposure. #rabiesbat #PublicHealth #InfectiousDisease #OneHealth #HealthAwareness #MedicalEducation
