Overview

Uncovers resistance mechanisms in multiple myeloma cells treated with mezigdomide, suggesting pathways for overcoming drug resistance.

Key Points

  • The aim is to identify factors contributing to resistance against the novel cereblon modulator mezigdomide in multiple myeloma cells.
  • Used multiple myeloma cell lines varying in sensitivity to mezigdomide
  • Analyzed cereblon, IKZF1, and IKZF3 expression levels through Western blotting
  • Conducted RNA sequencing to identify gene expression changes
  • Validated candidate resistance genes using RT-PCR
  • Expression levels of CRBN, IKZF1, and IKZF3 were similar in sensitive and resistant cells
  • RNA sequencing identified several differentially expressed genes associated with resistance
  • Distinct gene expression patterns were confirmed between resistant and sensitive cell lines
