pubmed:abstractText |
Human cytomegalovirus (HCMV) induces morphological changes in infected cells that are remarkably similar to those seen in oncogenically transformed cells. The molecular bases of these phenotypic alterations are not known but their occurrence in some transformed cells can be associated with abnormal fibronectin (FN) expression. In this report, we have compared FN levels in normal and HCMV-infected cells. In these studies, the HCMV-infected fibroblasts exhibited a progressive loss of cellular FN. Northern (RNA) blot analysis revealed that the decrease in FN levels resulted from a lowering of FN mRNA levels in HCMV-infected cells. We detected an initial decrease in FN mRNA of 25 to 30% at immediate-early and early times, whereas at late times after infection the levels of FN mRNA were lowered by greater than 80%. These results indicated that the HCMV-induced decrease in FN expression is due to a decrease in the quantity of FN mRNA and suggested that HCMV-encoded and/or -induced functions may be involved in producing these alterations.
