Deep dives

Role of NSD2 in Multiple Myeloma Cells

NSD2 is crucial for maintaining the identity of multiple myeloma cells as plasma cells, which are essential for immune function. The research revealed that high activity of the NSD2 gene influences DNA folding and the activation or silencing of various genes that are vital for plasma cell characteristics. When NSD2 activity was turned off, significant markers such as CD38 significantly decreased, while genes usually inactive in plasma cells became activated. This suggests that NSD2 does not directly control the primary genes for plasma cell creation but rather affects a multitude of other genes that help sustain the cancer cell's identity.
