pubmed-article:293685 | pubmed:abstractText | We have recently demonstrated that normal hemopoietic cells express RNA sequences that are homologous to sequences specific for the Friend erythroleukemia virus genome [Bernstein, A., Gamble, C., Penrose, D. & Mak, T. W. (1979) Proc. Natl. Acad. Sci. USA 76, 4455-4459]. In this communication, we report that the Fv-2 locus, the major genetic determinant controlling host susceptibility to erythroleukemia induction by Friend leukemia virus, also controls the expression of endogenous sequences related to the replication-defective component of Friend leukemia virus, Friend spleen focus-forming virus (SFFV), in normal uninfected mice. Two independent congeneic pairs of mice [C57BL/6 (B6) and B6.S; B6 and B6.C(H-7(b))], differing only in a small region of the mouse genome including the Fv-2 locus, were used for this purpose. In both cases, molecular hybridization analysis indicated that the presence of SFFV-related RNA sequences in normal mice was associated with the Fv-2(s) allele: bone marrow or spleen cellular RNA from Fv-2(rr) B6 mice contained no detectable SFFV-related sequences, whereas their congeneic Fv-2(ss) pairs contained relatively high levels of these RNA sequences. The absence of these RNA sequences in Fv-2(rr) mice was not due to deletion of these sequences from the DNA of Fv-2(rr) mice. Repopulation of lethally irradiated Fv-2(rr) mice with syngeneic Fv-2(rr) bone marrow cells did not lead to any increase in the levels of these SFFV-related RNA sequences, suggesting that the expression of these sequences is still reduced or inhibited in actively cycling Fv-2(rr) hemopoietic cells. Infection with Friend leukemia virus resulted in the appearance of high levels of RNA homologous to SFFV-specific sequences in the leukemic spleens of B6.S (Fv-2(ss)) mice, whereas these cellular RNA sequences could not be detected in the spleens of Friend virus-infected B6 (Fv-2(rr)) mice. The demonstration that the same gene locus controls both the expression of exogenous SFFV-specific sequences and erythroleukemia induction by Friend leukemia virus suggests that these sequences may be necessary for erythroleukemic transformation. In addition, the finding that the Fv-2 gene locus controls the expression of endogenous SFFV-related sequences suggests that these sequences may also be involved in normal hemopoiesis. | lld:pubmed |
