Prader-Willi syndrome (PWS [MIM 176270]) is a neurogenetic disorder characterized by decreased fetal activity, muscular hypotonia, failure to thrive, short stature, obesity, mental retardation, and hypogonadotropic hypogonadism. It is caused by the loss of function of one or more imprinted, paternally expressed genes on the proximal long arm of chromosome(More)
(1R,2R,6S)-3-Methyl-6-(prop-1-en-2-yl)cyclohex-3-ene-1,2-diol 1 possesses potent antiparkinsonian activity in both MPTP and haloperidol animal models. The use of compound 1 resulted in nearly full recovery of the locomotor and exploratory activities and was as effective as the comparator agent (levodopa). All eight stereoisomers of compound 1 have been(More)
The tumour suppressor p53 is a crucial regulator of cell cycle arrest and apoptosis by acting as a transcription factor to regulate a variety of genes. At least in part, this control is exerted by p53 via regulating expression of numerous microRNAs. We identified two abundantly expressed microRNAs, miR-16 and miR-26a, whose expression is regulated by p53(More)
26S proteasomes are known as major non-lysosomal cellular machines for coordinated and specific destruction of ubiquitinylated proteins. The proteolytic activities of proteasomes are controlled by various post-translational modifications in response to environmental cues, including DNA damage. Besides proteolysis, proteasomes also associate with RNA(More)
In order to achieve a better outcome for pancreatic cancer patients, reliable biomarkers are required which allow for improved diagnosis. These may emanate from a more detailed molecular understanding of the aggressive nature of this disease. Having previously reported that Notch3 activation appeared to be associated with more aggressive disease, we have(More)
Functional F and null 0 alleles of the CAD1 (Aadh1) gene, which controls the biosynthesis of aromatic alcohol dehydrogenase, were studied in hybrids of the diploid wheat T. monococcum L. and Triticum sinskajae A. Filat. et Kurk. The gene CAD1 is located in chromosome 5A and is linked with the awnless gene awnS (La) with a recombination frequency of about(More)
The synthesis of lignin and its deposition in secondary cell walls leads to the formation of sclerenchyma, a tissue having mechanical strength. This biochemical mechanism arose about 400–420 million years ago, in the Early Silurian period, in the first vascular plants (Tracheophyta order). The appearance of sclerenchyma is related to the emergence of plants(More)
Differences in isoenzyme pattern of aromatic alcohol dehydrogenase, NADP-AADH or CAD, were found in the Triticum aestivum L. winter bread wheat cultivars by the method of electrophoresis in the starch gel. A standard three-component spectrum is present in the cv. Zitnica (former Yugoslavia); additional fact-migrating isoenzymes appear in the cv.(More)
In carrying out a genetic analysis of rye in terms of a “brittle stem” trait, sister plants with normal and brittle stems were obtained. The culms of plants were studied in terms of chemical composition, spectroscopic parameters, and mechanical strength. Differences among plants with different types of culm were found in terms of a number of indicators,(More)
