• Gramine Drives Ferroptosis in TNBC via CUL3–MTDH

  2026-08-24

  A 2026 study identifies Gramine as a selective suppressor of triple-negative breast cancer through a previously uncharacterized CUL3–MTDH regulatory axis. By combining target-engagement assays, ferroptosis rescue experiments, gene knockdown, and xenograft models, the authors connect CUL3 inhibition and MTDH stabilization with lipid-peroxidation-associated cancer cell death.

• BH3-Mimetic Targeting in Glioblastoma

  2026-08-24

  Koessinger and colleagues show that glioblastoma is unusually dependent on anti-apoptotic BCL-xL and MCL-1, including in stem-like tumor-cell populations. Their results support sequential BH3-mimetic targeting as a strategy for exploiting apoptotic priming while highlighting the need to validate molecular dependency and treatment schedule in clinically relevant models.

• Cycloheximide: Translation Blockade in Apoptosis Assays

  2026-08-23

• Poly-PR, NEAT1, and HSP70 in TDP-43 Condensates

  2026-08-20

  The reference study identifies a NEAT1-dependent pathway through which C9ORF72-derived poly-PR drives TDP-43 nuclear condensation and subsequent proteinopathy. Its findings position HSP70 as a dynamic regulator of condensate fluidity, linking transient chaperone recruitment with protection and prolonged stress with HSP70 loss, TDP-43 oligomerization, and toxicity.
