<p>We examined the effects of gamma-secretase inhibition (GSI) on the bone marrow microenvironment in multiple myeloma patients before anti-B-cell maturation antigen (<a href="https://www.ncbi.nlm.nih.gov/gene/608">BCMA</a>) CAR T-cell therapy. Single-nuclei RNA and ATAC sequencing revealed significant changes in gene expression and chromatin accessibility, especially in monocytes and tumor cells, following exposure to GSI. The findings suggest that GSI influences not only BCMA signaling but also broader cellular interactions within the tumor microenvironment. De-identified sequencing data from the study is available through dbGaP.</p>
