Abstract

Viral transcripts, particularly those of the regulatory genes (e.g., rev) in lymphocytic cells chronically infected with human immunodeficiency virus type 2, consist of two types, differing in the structure of the leader sequence derived from the 5' long terminal repeat (LTR). Some transcripts undergo a specific splicing event within the 5' LTR, removing an intron consisting of a part of the R region whereas others do not. Because this spliced-out R region is a part of the trans-activation response element (TAR), it could influence trans-activator (Tat)-mediated trans-activation of viral gene expression. Moreover, this part of the R region is predicted to contain a stable secondary structure that could affect the efficiency of translation of the transcripts without this splicing. Thus, the 5' LTR splicing could have important consequences for virus replication, latency, and pathogenicity.

miR-503-3p promotes epithelial-mesenchymal transition in breast cancer by directly targeting SMAD2 and E-cadherin.

Although progress in clinical and basic research has significantly increased our understanding of breast cancer, little is known about the molecular mechanism underlying breast cancer metastasis. Identification of effective therapeutic targets to prevent breast cancer metastasis is urgently needed. The function of miR-503-3p has been investigated in other cancers, but its role in breast cancer remains undefined. Here, we found that miR-503-3p was overexpressed in breast cancer tissue and plasma compared with adjacent normal breast tissue and with plasma from healthy individuals. Moreover, we identified miR-503-3p to be an oncogene of breast cancer cell proliferation, migration and invasion. Upregulation of miR-503-3p in breast cancer cells inhibited expression of epithelial-mesenchymal transition (EMT)-related protein SMAD2 and the epithelial marker protein E-cadherin by directly binding to their mRNA 3' untranslated region, whereas increased expression of mesenchymal marker proteins, including vimentin and N-cadherin. Taken together, our findings support a critical role for miR-503-3p in induction of breast cancer EMT and suggest that plasma miR-503-3p may be a useful diagnostic biomarker for breast cancer.

Identification and characterization of Prp45p and Prp46p, essential pre-mRNA splicing factors.

Through exhaustive two-hybrid screens using a budding yeast genomic library, and starting with the splicing factor and DEAH-box RNA helicase Prp22p as bait, we identified yeast Prp45p and Prp46p. We show that as well as interacting in two-hybrid screens, Prp45p and Prp46p interact with each other in vitro. We demonstrate that Prp45p and Prp46p are spliceosome associated throughout the splicing process and both are essential for pre-mRNA splicing. Under nonsplicing conditions they also associate in coprecipitation assays with low levels of the U2, U5, and U6 snRNAs that may indicate their presence in endogenous activated spliceosomes or in a postsplicing snRNP complex.

Interaction of retroviral reverse transcriptase with template-primer duplexes during replication.

Conversion of the single-stranded RNA of an invading retrovirus into double-stranded proviral DNA is catalyzed in a multi-step process by a single virus-coded enzyme, reverse transcriptase (RT). Achieving this requires a combination of DNA polymerase abd ribonuclease H (RNase H) activities, which are located at the amino and carboxy terminus of the enzyme, respectively. Moreover, proviral DNA synthesis requires that three structurally-distinct nucleic acid duplexes are accommodated by this enzyme, namely (a) A-form RNA (initiation of minus strand synthesis), non-A, non-B RNA/DNA hybrid (minus strand synthesis and initiation of plus strand synthesis) and B-form duplex DNA (plus strand synthesis). This review summarizes our current understanding of the manner in which retroviral RT interacts with this diverse array of nucleic acid duplexes, exploiting in many cases mutants unable to catalyze a specific event. These studies illustrate that seemingly 'simple' events such as tRNA-primed initiation of minus strand synthesis are considerably more complex, involving intermolecular tRNA-viral RNA interactions outside the primer binding site. Moreover, RNase H activity, generally thought to catalyze non-specific degradation of the RNA-DNA replicative intermediate, is required for highly specialized events including DNA strand transfer and polypurine selection. Finally, a unique structure near the center of HIV proviral DNA, the central termination sequence, serves to halt the replication machinery in a manner analogous to termination of transcription. As these highly specialized events are better understood at the molecular level, they may open new avenues of therapeutic intervention in the continuing effort to stem the progression of HIV infection and AIDS.
