Thus, the occurrence of multiple bands in NCI-H929 can be attributed to this N-glycosylation phenomenon, as elucidated by Huang et al. As a result, we employed K562 cells as negative target cells (BCMAneg), while KMS-12-PE (BCMAlow) and NCI-H929 (BCMAhigh) cells were utilized as MM target cells with varying levels of BCMA expression to assess the efficacy of CAR T cells. The gene discussed is TNFRSF17; the disease is Miyoshi myopathy.
