We identified cytosine-rich regions adjacent to guanine-rich regions in the TMPRSS2 gene, which showed structural competition between a G-quadruplex and a hairpin loop. Furthermore, this competition significantly affected transcription efficiency.

Enhancement of the Catalytic Activity of Hammerhead Ribozymes by Organic Cations. Reviewed International journal

Catalytic turnover is important for the application of ribozymes to biotechnology. However, the turnover is often impaired because of the intrinsic high stability of base pairs with cleaved RNA products. Here, organic cations were used as additives to improve the catalytic performance of hammerhead ribozyme constructs that exhibit different kinetic behaviors. Kinetic analysis of substrate cleavage demonstrated that bulky cations, specifically tetra-substituted ammonium ions containing pentyl groups or a benzyl group, have the ability to greatly increase the turnover rate of the ribozymes. Thermal stability analysis of RNA structures revealed that the bulky cations promote the dissociation of cleaved products and refolding of incorrectly folded structures with small disruption of the catalytic structure. The use of bulky cations is a convenient method for enhancing the catalytic activity of hammerhead ribozymes, and the approach may be useful for advancing ribozyme technologies.

Detection of Intracellular Reactive Oxidative Species Using the Fluorescent Probe Hydroxyphenyl Fluorescein Invited Reviewed

Various fluorescent probes for the detection of intracellular reactive oxidative species (ROS) have been developed because ROS levels are closely associated with cellular states. Here, we describe a method for detection of intracellular ROS in living cells using the fluorescent probe, hydroxyphenyl fluorescein (HPF), which detects hydroxyl radicals and peroxynitrite. NIH3T3 cells and p53 knockout (p53−/−) mouse embryonic fibroblasts (MEFs) were transformed by expressing oncogenic RAS using a retrovirus system. The cells were treated with HPF at 37 °C for 30 min, and subsequently, images were acquired using a confocal fluorescence microscope at an excitation wavelength of 488 nm after washing with PBS.
