Detection of c-rel-related transcripts in mouse hematopoietic tissues, fractionated lymphocyte populations, and cell lines.

Abstract

A portion of the human cellular homolog of v-rel, the transforming gene of the leukemogenic retrovirus reticuloendotheliosis virus, strain T, was used to survey RNAs from several mouse tissues, selected lymphocyte populations, and hematopoietic cell lines for c-rel expression. Relatively high levels of a high-molecular-weight transcript were observed in peripheral B and T cells, whereas lower levels were detectable in functionally immature thymocytes. These results suggested that, unlike c-myb and c-ets, the c-rel proto-oncogene plays a role in later stages of lymphocyte differentiation.
