A proteomic approach for studying LTR retrotransposon host factors in saccharomyces cerevisae
The Ty retrotransposons of S. cerevisiae are mobile elements that resemble retroviruses, both in their genetic structures and replication cycles. Ty retrotransposition begins in the nucleus with the transcription of Ty RNA. Following translation of Ty proteins, virus-like particles (VLPs) assemble …

The Influence of HIV-1 Subtype C LTR Genotype on Latency Potential
… of the HIV-1 promoter, the long terminal repeat (LTR), has been shown to influence latency establishment in in vitro models. We investigated the influence of inter-participant subtype C LTR genotypic variation on the establishment of latency in a dual reporter HIV-1 plasmid model and evaluated …

Non-LTR Retrotransposons in Mosquitoes: Diversity, Evolution, and Analysis of Potentially Active Elements
… focuses on non-Long Terminal Repeat (non-LTR) retrotransposons in the African malaria mosquito, Anopheles gambiae and other mosquito species. An unprecedented diversity of non-LTRs was discovered by genome analysis of the An. gambiae genome assembly. One hundred and four families were …

Cell intrinsic innate immunity protein RPRD2 restricts transcription from the HIV-1 LTR in human cell lines
… 293T cells transfected with a GFP tagged HIV-1 LTR driven reported vector. Interestingly when RPRD2 is transiently knocked down in HeLa cells there is no effect on HIV-1 LTR GFP reporter expression. Our results propose a novel role for RPRD2 in the transcriptional repression of HIV-1, which may …

Idempotents in group rings
… idempotents. Instead, we study the lifted trace ltr. For e = e² ∊ k[G], define ltr(e) by ê(1) where ê = Σ{x ∊ G}ê(x)x lifts e. Here ê is an infinite series with |ê(x)|<sub>p</sub>→0, where each ê(x) lives in the Witt vector ring of k. We prove that ltr(e) depends on e only, it is a p-adic …

Studies on the Activity of the Long Terminal Repeat of Rous Sarcoma Virus in Animal Cells and in Yeast
… Rous sarcoma virus (RSV) Long terminal repeat (LTR) in untransformed rat 3Y1 fibroblasts is dependent on the presence of serum. Within an hour of addition of serum to a serum-deprived culture there is a 5 fold stimulation in the level of transcripts initiated at the LTR. This stimulation does …

Role of the glucocorticoid receptor and HIV-1 Vpr in inflammatory gene expression and HIV-1 LTR transcription in response to dexamethasone and progestogens
The relationship between progestin-only injectable contraception and risk of HIV-1 acquisition is controversial. Most clinical data suggests that the injectable contraceptive medroxyprogesterone acetate (MPA), unlike norethisterone enanthate (NET-EN), increases susceptibility to infections such as …
