🚀From Bench to Paper | Can stress granules control ferroptosis? #Glioblastoma #StemCells (GSCs) are highly resistant to irradiation (IR) and temozolomide (TMZ), driving treatment failure and recurrence. This study reveals a previously unrecognized link between #StressGranules (SGs) and #ferroptosis. ⚙️Disrupting SGs sensitizes GSCs to IR/TMZ by promoting ferroptosis. SG profiling reveals enrichment of iron-related proteins, including ferritin. Mechanistically, the SG core protein G3BP1 binds ferritin light chain in an IR/TMZ-induced methionine-333 oxidation–dependent manner. This promotes ferritin sequestration into stress granules, leading to: → reduced labile Fe²⁺ pool → suppression of ferritinophagy → inhibition of ferroptosis 🧬A screened small molecule, #ciwujianoside C3, disrupts the G3BP1–ferritin interaction: √ restores ferroptotic sensitivity √ resensitizes GSCs to IR/TMZ √ shows efficacy in both in vitro and in vivo models Overall, this study identifies a novel SG–ferroptosis axis, positioning stress granules as key regulators of iron metabolism and a therapeutic vulnerability in glioblastoma. 🔗 MedChemExpress research tools & reagents used in this study 4-HNE antibody, #CWJC3, adenosine amine congener, aucubin, puromycin, liproxstatin-1, temozolomide (TMZ), DFO, chloroquine, bafilomycin A1, γ-linolenic acid, α-eleostearic acid, ferrostatin-1, PROTAC-MLKL, GSK2606414, G3Ia, G3Ib, A769662 #CancerResearch #NeuroOncology #CellDeath #DrugDiscovery

💊FDA Approval Update | The #FDA has approved #Hepcludex (#bulevirtide-gmod) as the first treatment for chronic #Hepatitis Delta Virus (#HDV) infection. 🦠HDV is the most severe form of viral hepatitis and only occurs in individuals already infected with Hepatitis B virus (#HBV), often leading to rapid progression to cirrhosis, liver failure, and hepatocellular carcinoma. 💡The newly approved therapy works by blocking viral entry into hepatocytes, representing the first targeted mechanism specifically addressing HDV infection. Why this matters: 🧬A historic milestone in viral hepatitis therapy 📈Addresses a rare but highly aggressive and life-threatening disease 💊Offers a new treatment pathway for a patient population with extremely limited options 🧪Explore @MedChemExpress's bulevirtide for research use: medchemexpress.com/bulevirtide.ht… 🧪More hepatitis virus-related research tools: medchemexpress.com/disease-areas/… #FDAApproval #Hepatology #HepatitisDelta #Virology #PharmaNews #DrugDiscovery #InfectiousDiseases

🔥Hot Off the Press | Nb-PROTAC Enables Broad-Spectrum Anti-Influenza Breakthrough #InfluenzaA viruses continue to pose a major global health challenge due to rapid mutation and frequent drug resistance. A new study introduces a nanobody-based #PROTAC (Nb-PROTAC) strategy that shifts antiviral therapy from functional inhibition to targeted viral protein degradation. 🚀By fusing NP-specific nanobodies with the VHL E3 ligase component, the system directly drives degradation of the highly conserved influenza nucleoprotein (NP), offering a novel antiviral modality. ✔️ Pan-subtype NP degradation across all 16 influenza A subtypes (H1–H16) ✔️ Strong inhibition of H1N1, H3N2, H5N1, H7N9, and H9N2 replication ✔️ In vivo AAV-LungM3 delivery achieved 90% (H1N1) and 80% (H5N1) survival in lethal models ✔️ Mechanistically involves the autophagy–lysosome pathway, with OPTN participation Nb-PROTAC represents a modular and programmable antiviral platform with strong potential for broad-spectrum and next-generation infectious disease control.

🚀From Bench to Paper | Dormant Ribosomes Wake Up Faster with #SNOR How do cells rapidly resume protein synthesis after nutrient starvation? Using in situ cryo-electron tomography (cryo-ET), researchers identified SNOR, a ribosome-associated factor that binds the peptidyl transferase center during glucose deprivation. Rather than acting as a canonical hibernation factor, SNOR functions as a licensing factor that prepares ribosomes for rapid reactivation. Upon glucose replenishment, SNOR cooperates with #eIF5A to rebuild polysomes, restart translation, and drive exit from cellular dormancy. 🧬These findings reveal a stress-responsive ribosome restart module that links carbon-source limitation to active-site surveillance and efficient reactivation of protein synthesis. ow.ly/tkAz50Z314a 🔬MCE offers GC7 sulfate, a widely used tool for eIF5A-related research. ow.ly/rMlY50Z3145 #RibosomeHibernation #TranslationalRestart #NutrientLimitation #CryoET #MCE #MedChemExpress
