Abstract

MERLOT, a molecular replacement computer package, has been successfully used for the determination of initial phases for five different oligonucleotide structures. Two of these, CCGG and CGCGCGTTTTCGCGCG, with 316 and 323 non-H atoms respectively in the asymmetric unit, have been solved ab initio using the MERLOT package. The rest are re-examinations of previously solved DNA oligomer structures, ioCCGG, CGCGAATTCGCG and CGCGAATTbrCGCG, with 160, 486 and 488 non-H atoms in the asymmetric unit respectively. Problems involved in applying the molecular-replacement technique to DNA structures, and their possible solutions, are discussed.

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.

Analysis of DNA-microarrays produced by inverse in situ oligonucleotide synthesis.

5'-Phosphoramidites protected by 2-nitrophenylethyl (NPE) and 2-(4-nitrophenyl)ethoxy carbonyl (NPEOC) functions were employed for in situ synthesis of oligonucleotides in 5'-->3' direction on flat glass surfaces. By this inverse synthesis format, the oligonucleotides are attached to the solid support via their 5'-ends while the free 3'-hydroxyl groups are available as substrates for enzymatic reactions such as elongation by polymerases, thereby adding another feature to the portfolio of chip-based applications. Having a fluorescence dye present at the first base during synthesis, the quality of the oligonucleotides was analysed quantitatively by capillary electrophoresis after release from the solid support. With about 95% yield per condensation, it was found to be equivalent to synthesis results achieved on CPG support. The chip-bound oligonucleotides could be extended enzymatically upon hybridisation of a DNA-template. Surprisingly, however, only 63% of the oligonucleotides were elongated in polymerase reactions, while oligonucleotides that were released from the support behaved normally in standard PCR amplifications. This rate of 63% nevertheless compares favourably with an extension rate of only 50%, which was achieved under identical conditions, if pre-fabricated oligonucleotides of identical sequence had been spotted to the glass support.
