Expression of RAN, ZHX-2, and CHC1L genes in multiple myeloma patients and in myeloma cell lines treated with HDAC and Dnmts inhibitors
In myeloma patients we observed significant changes in the expression of RAN, ZHX-2, and CHC1L genes, but it was patient-specific. Our experiments illustrate new methodological approaches and troubleshooting for conducting gene expression st...
