Estrogen induces a global change in the translation profile of Xenopus hepatocytes, replacing serum protein synthesis with production of the yolk protein precursor vitellogenin. This is accomplished by the coordinate destabilization of serum protein mRNAs and the transcriptional induction and subsequent stabilization of vitellogenin mRNA. Previous work identified an endonuclease activity whose appearance on polysomes correlated with the disappearance of serum protein mRNAs. This enzyme, polysomal ribonuclease 1 (PMR1), is a novel member of the peroxidase gene family. The current study examined the association of PMR1 with its mRNA targets on polysomes and mRNPs. The highest amount of polysome-bound PMR1 was observed prior to estrogen induction of mRNA decay. Its distribution on sucrose density gradients matched the absorbance profile of polysome-bound mRNA, suggesting that PMR1 forms a latent complex with mRNA. Following dissociation with EDTA the 62 kDa PMR1 sedimented with a larger complex of >670 kDa. Estrogen induces a 22-fold increase in unit enzymatic activity of polysome-bound PMR1, and a time-dependent loss of PMR1 from polysomes in a manner that mirrors the disappearance of albumin mRNA. These data suggest that the key step in the extensive estrogen-induced change in mRNA decay in Xenopus liver is activation of a latent mRNA endonuclease associated with its target mRNA.

With efforts underway to develop a preventive human immunodeficiency virus type 1 (HIV-1) vaccine, it remains unclear which immune responses are sufficient to protect against infection and whether prior HIV-1 immunity can alter the subsequent course of HIV-1 infection. We investigated these issues in the context of a volunteer who received six HIV-1LAI envelope immunizations and 10 weeks thereafter acquired HIV-1 infection through a high-risk sexual exposure. In contrast to nonvaccinated acutely infected individuals, anamnestic HIV-1-specific B- and T-cell responses appeared within 3 weeks in this individual, and neutralizing antibody preceded CD8+ cytotoxic responses. Despite an asymptomatic course and an initial low level of detectable infectious virus, a progressive CD4+ cell decline and dysfunction occurred within 2 years. Although vaccination elicited immunity to HIV-1 envelope, which was recalled upon HIV-1 exposure, it was insufficient to prevent infection and subsequent immunodeficiency.
