Stable RNAs are central to protein synthesis. Ribosomal RNAs make the core of the ribosome and provide the scaffold for accurate translation of mRNAs by a set of tRNA molecules each carrying an activated amino acid. To fulfill these important cellular functions, both rRNA and tRNA molecules...
The hemocytes are the cells responsible for the immune response in marine mollusks. The role of NO in processes related to the activation of the hemocytes has turned out evident over the late years. In the case of the mussel Mytilus galloprovincialis Lmk., hemocyte NO basal production varies...
An analysis of several features of marsupial oocytes and developmental stages from the zygote to the neonate shows the advantages of studying these to answer questions about mammalian development in general. Marsupials make good model systems providing that species have well established breeding...
Here we have identified 18 different box C/D snoRNAs encoded in six new gene clusters by the screening of Oryza sativa (rice) genome sequences using a computer program that we have designed to search for non‐canonical box C and D sequences. Among this snoRNA collection, five are homologues of...
Nitration of tyrosine, in both protein‐bound form and free amino acid form, can readily occur in cells under oxidative/nitrative stress. In addition to serving as a biomarker of oxidative/nitrative stress, elevated levels of nitrotyrosine have been shown to cause DNA damage or trigger...
Coenzyme Q10 (CoQ10, ubiquinone) is an essential cofactor in the electron transport chain, serves as a potent antioxidant in mitochondria and lipid membranes, and is often used as a dietary supplement for a number of diseases including cardiovascular diseases. Recently, we obtained evidence that...
DNA‐binding Proteins from Starved cells (Dps) are anti‐stress iron proteins preserving bacteria from oxidative damage. Based on sequence alignment, a 564‐bp open reading frame (all1173) encoding product in Anabaena sp. PCC 7120 shared high similarity with Dps family proteins. RT‐PCR...
