This finding highlights the functional relevance of IMiD's inherent polypharmacology in circumventing primary resistance mechanisms at the cellular level. Together, our results identify the ARID2-containing PBAF complex as a critical vulnerability in resistant myeloma cells and provide a mechanistic rationale for designing combination strategies that co-target this complex, with the potential to enhance therapeutic efficacy by overcoming drug resistance.

A bifunctional PROTAC, namely dSLC7A11, ws designed by conjugating the SLC7A11 inhibitor sulfasalazine to the CRBN ligand pomalidomide via an alkyl linker. Notably, dSLC7A11 exhibited superior antitumor efficacy over sulfasalazine alone, and achieved an effect of suppressing tumor growth by >65% in vivo. This study presented a SLC7A11-targeting PROTAC that disrupts the cellular antioxidant defense system, thus establishing a novel PROTAC-based approach for potent ferroptosis induction in cancer therapy.

Analysis of the FAERS database revealed that the PD-L1 inhibitor durvalumab is significantly associated with TB-related adverse events (reporting odds ratio = 7.81; 95% CI: 4.43-13.78; P = 1.10×10-18)...In silico drug prediction and molecular docking suggested several PD-L1-modulating compounds, including ruthenium, pomalidomide, zidovudine, and lycorine...Together, our findings define a mechanistic axis in CD14- CD16+ monocytes that underpins early TB control and is vulnerable to PD-L1 blockade. Collectively, these findings align with the established notion that assessing latent tuberculosis infection before initiating immune-modulating therapies is essential for minimizing reactivation risk, and propose tractable molecular targets for preventing TB reactivation in immunocompromised hosts.

Post-hoc analysis of the OCEAN trial melflufen-treated del(17p) patient population also demonstrated favorable progression free survival compared to pomalidomide-treated cohort. Our insights into the molecular mechanisms of melflufen activity in TP53-/- myeloma support its clinical efficacy and application in the del(17p) and TP53-/- patient population.Trial registration NCT03151811, registration 2017-05-09.
