Telomere synthesis depends on telomerase, which contains an RNA subunit linked to a specialized reverse transcriptase subunit and several associated proteins. Here we report the characterization of four mutations in the yeast reverse transcriptase subunit ...
Quantitative PCR (qPCR) is a powerful technique that is now commonly used in many research and clinical laboratories. Although it allows precise quantification of specific DNA sequences, it is often not used at its full potential. A number of data collecti ...
BACKGROUND AND AIMS: Liver inflammation, fibrosis, and dyslipidemia are common features in patients with chronic hepatitis C virus (HCV) infection. Because peroxisome proliferator-activated receptor alpha (PPARalpha) is highly expressed in the liver and is ...
Telomerase is the ribonucleoprotein reverse transcriptase that adds telomeric DNA repeats to the ends of chromosomes. This involves annealing of the telomerase RNA template to the 3' end of the chromosome, reverse transcription of the RNA template by the t ...
A review. Directed evolution consists of repetitive cycles of random mutagenesis of the protein/peptide sequence followed by screening or selection of candidates with desired properties. Many different approaches are used to introduce mutations into a gene ...
Quantitative reverse transcriptase real-time PCR (QRT-PCR) is a robust method to quantitate RNA abundance. The procedure is highly sensitive and reproducible as long as the initial RNA is intact. However, breaks in the RNA due to chemical or enzymatic clea ...
Neocortical neurones can be classified according to several independent criteria: morphological, physiological, and molecular expression (neuropeptides (NPs) and/or calcium-binding proteins (CaBPs)). While it has been suggested that particular NPs and CaBP ...
Sphingomonas paucimobilis B90A is able to degrade the alpha-, beta-, gamma-, and delta-isomers of hexachlorocyclohexane (HCH). It contains the genes linA, linB, linC, linD, linE, and linR, which have been implicated in HCH degradation. In this study, dynam ...
Uncoupling proteins (UCPs) present in the inner mitochondrial membrane are involved in uncoupling respiration from ATP synthesis. Five UCP isoforms have been identified but information about their presence and level of expression in the central nervous sys ...
A new 9.9 kb catabolic transposon, Tn-Dha1, containing the gene responsible for tetrachloroethene (PCE) reductive dechlorination activity, was isolated from Desulfitobacterium hafniense strain TCE1. Two fully identical copies of the insertion sequence ISDh ...
