NFS1, together with FXN, protects cells from ferroptosis and DNA damage in diffuse large B-cell lymphoma.

ABSTRACT: Diffuse large B cell lymphoma (DLBCL) is a common hematologic malignancy. NFS1 cysteine desulfurase, as a rate-limiting enzyme in the iron-sulfur cluster (ISC) biogenesis, has been reported to be associated with tumor progression. However, the role of NFS1 in DLBCL remains elusive. Here, we showed an upregulation of NFS1 in DLBCL tumor tissues. Knockdown of NFS1 decreased the cell viability and enhanced LDH levels in DLBCL cells. Animal experiments further indicated that downregulation of NFS1 suppresses tumor growth in vivo. NFS1 knockdown increased the lipid reactive oxygen species (ROS) level in cells, and this promotional effect was reversed by ferroptosis inhibitors, but not influenced by other types of cell death inhibitors. This result suggested that NFS1 depletion-impaired cell via
