Abstract

Currently available approaches to molecular-scale logic gates are summarized and compared. These include: chemically-controlled fluorescent and transmittance-based switches concerned with small molecules, DNA oligonucleotides with fluorescence readout, oligonucleotide reactions with DNA-based catalysts, chemically-gated photochromics, reversibly denaturable proteins, molecular machines with optical and electronic signals, two-photon fluorophores and multichromophoric transient optical switches. The photochemical principles of electron and energy transfer are involved in several of these approaches. More complex molecular logic systems with reconfigurability and superposability provide contrasts with current semiconductor electronics. Integration of simple logic functions to produce more complex ones is also discussed in terms of recent developments.

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.

The strong efficiency of the Escherichia coli gapA P1 promoter depends on a complex combination of functional determinants.

The Escherichia coli multi-promoter region of the gapA gene ensures a high level of GAPDH (glyceraldehyde-3-phosphate dehydrogenase) production under various growth conditions. In the exponential phase of growth, gapA mRNAs are mainly initiated at the highly efficient gapA P1 promoter. In the present study, by using site-directed mutagenesis and chemical probing of the RPo (open complex) formed by Esigma70 (holoenzyme associated with sigma70) RNAP (RNA polymerase) at promoter gapA P1, we show that this promoter is an extended -10 promoter that needs a -35 sequence for activity. The -35 sequence compensates for the presence of a suboptimal -10 hexamer. A tract of thymine residues in the spacer region, which is responsible for a DNA distortion, is also required for efficient activity. We present the first chemical probing of an RPo formed at a promoter needing both a -10 extension and a -35 sequence. It reveals a complex array of RNAP-DNA interactions. In agreement with the fact that residue A-11 in the non-template strand is flipped out in a protein pocket in previously studied RPos, the corresponding A residue in gapA P1 promoter is protected in RPo and is essential for activity. However, in contrast with some of the previous findings on RPos formed at other promoters, the -12 A:T pair is opened. Strong contacts with RNAP occur both with the -35 sequence and the TG extension, so that the sigma4 and sigma2 domains may simultaneously contact the promoter DNA. RNAP-DNA interactions were also detected immediately downstream of the -35 hexamer and in a more distal upstream segment, reflecting a wrapping of RNAP by the core and upstream promoter DNA. Altogether, the data reveal that promoter gapA P1 is a very efficient promoter sharing common properties with both extended -10 and non-extended -10 promoters.

Tetracycline-regulated expression enables purification and functional analysis of recombinant connexin channels from mammalian cells.

Intercellular coupling mediated by gap junction channels composed of connexin protein underlies numerous physiological processes, such as cellular differentiation, tissue synchronization and metabolic homoeostasis. The distinct molecular permeability of junctional channels composed of different connexin isoforms allows cellular control of coupling via regulation of isoform expression. However, the permeability properties of most connexin isoforms have not been well characterized due to the difficulty of manipulating and measuring the diffusible concentrations of cytoplasmic messenger molecules and metabolites, and to a lack of control over channel isoform composition, in vivo. Here we present a method to express and purify active connexin hemichannels of a single isoform or a consistent ratio of two isoforms from cultured cells using the Tet-On inducible expression system and one-step anti-haemagglutinin immunoaffinity purification. The procedure yields 10-20 microg of pure connexin protein from 2.5x10(8) HeLa cells. The purified channels are shown to be useful for in vitro permeability analysis using well established techniques. This method has substantial advantages over existing methods for heterologous connexin expression, such as the ease of co-expression of two isoforms at a constant ratio, consistently high expression levels over many passages, and the ability to study channel properties in situ as well as in purified form. Furthermore, the generic cloning site of the new pBI-GT vector and the commercial availability of anti-haemagglutinin (clone HA-7)-agarose make this affinity tagging and purification procedure easily applicable to other proteins.
