• VX-661 and the Next Era of CFTR Rescue

  2026-09-05

  VX-661, a F508del CFTR corrector, offers more than a trafficking-rescue tool: it provides a way to interrogate how protein folding, calnexin-dependent proteostasis, variant biology, and potentiator timing shape translational cystic fibrosis research.

• DCPS and m7G Signaling in Diabetic Foot Ulcers

  2026-09-04

  A 2025 study identified the m7G-related decapping scavenger enzyme DCPS as a candidate biomarker and regulator of epithelial behavior in diabetic foot ulcers.
