Abstract

The nucleotide sequence analysis of insertion element IS1 has shown that IS1 could have as many as six translational reading frames encoding possible proteins. In order to determine which reading frames are actual structural genes responsible for IS1-mediated recombination, we introduced base substitution mutations including nonsense mutations into all of the potential reading frames and examined the ability of these IS1 mutants to mediate cointegration between two plasmids. The results reveal that IS1 has two structural genes (termed insA and insB), which are required for plasmid cointegration mediated by IS1.

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.

A 700 bp cis-acting region controls mating-type dependent recombination along the entire left arm of yeast chromosome III.

Homothallic switching of the mating-type MATa gene in Saccharomyces cerevisiae results from replacement by gene conversion of MAT-Ya DNA with Y(alpha) sequences copied from one of two unexpressed donors. MATa preferentially recombines with HML(alpha), located near the left end of chromosome III, but can use HMR(alpha), near the right chromosome end. MATa donor preference depends on a 700 bp orientation-independent cis-acting recombination enhancer, located 17 kb proximal to HML. Deletion of this element markedly reduces MATa's use of a donor inserted at any of four different locations along the leftmost 92 kb of chromosome III. This enhancer is sufficient for donor activation, since it stimulates use of the "wrong" donor, when it is inserted 7 kb proximal to HMR.
