The invention relates to application of SMARCC1 in preparation of a
medicine for treating
carfilzomib-resistant
multiple myeloma, and belongs to the technical field of biological
medicine. According to the invention, direct association between SMARCC1 and the
drug resistance of
multiple myeloma to
carfilzomib is determined for the first time, and the sensitivity of
drug-resistant cells to
carfilzomib can be significantly enhanced by down-regulating the expression of the
gene. Specifically, through systematic analysis on clinical data, SMARCC1 is found to be remarkably and highly expressed in relapse /
refractory MM patients and is closely related to poor survival. The SMARCC1 knock-down obviously inhibits the multiplication capacity of
multiple myeloma drug-resistant cells, so that the SMARCC1 not only promotes the multiplication capacity of the drug-resistant cells, but also is closely related to the
drug resistance of the multiple myeloma cells to carfilzomib, which prompts that the SMARCC1 can be used as a potential therapeutic target and is used for reversing the carfilzomib
drug resistance of multiple myeloma.
