Genetic Interaction Between Proto-Oncogene and Histocompatibility Antigen Gene Expressions in Cellular Differentiation of Mouse Neuroblastoma
The recognition of major histocompatibility complex (MHC) class I antigens plays an important role in the function of T cells in the immune system both at the regulatory and effector levels . It has been suggested that quantitative variations in target MHC class I expression would reversely influence natural killer cells (NK) compared to T cells , and that the MHC expression decreases as a tumor grows . On the other hand, there have been reports on a relationship among N-myc gene expression, cellular differentiation, and tumor progression in neuroblastoma [4,5]. The aim of this study was to examine the interaction of gene regulation between proto-oncogene (N-myc and c-src) and histocompatibility antigen gene expressions, using a dimethyl sulfoxide (DMSO)-induced differentiation model of mouse neuroblastoma.
