Disrupting myddosome assembly in diffuse large B‑cell lymphoma cells using the MYD88 dimerization inhibitor ST2825.

ABSTRACT: Diffuse large B‑cell lymphoma (DLBCL), the most common type of non‑Hodgkin's lymphoma, is classified into germinal center and activated B cell (ABC) subtypes. The myeloid differentiation primary response gene 88 (MYD88) L265P mutation is the most prevalent oncogenic mutation among patients with ABC DLBCL, the subtype that has the more inferior outcome. MYD88 oligomerization driven by the L265P mutant augments myddosome assembly and triggers the activation of nuclear factor kappa‑light‑chain‑enhancer of activated B cells (NF‑κB) signaling, highlighting MYD88 oligomerization as a potential therapeutic target for this malignancy. The synthetic peptidomimetic compound ST2825, which has previously been used as an anti‑inflammatory agent, has been reported to inhibit MYD88 dimerization. In the p
