Egfr ligand processing in Drosophila involves trafficking of the ligand precursor by the chaperone Star from the endoplasmic reticulum (ER) to a secretory compartment, where the precursor is cleaved by the intramembrane protease Rhomboid. Some of the Drosophila Rhomboids also reside in the ER, where they attenuate signaling by premature cleavage of Star. The genome of the flour beetle Tribolium...
Cationic polymers can be used as vectors to transport and efficiently protect nucleic acids. In this work we describe the synthesis of dense star-like 2-dimethylaminoethyl acrylate (DMAEA) and...
Several examples of natural mutants in the grass family were presented. All appeared as changes in inflorescence structure. In mutated plants chasmogamy was restricted due to anomalous lodicules or compactness of ears. A rare glumeless mutation in Agropyron pectiniforme reduced the level of assimilation in the ear. All mutations appear as unfavorable in natural populations.
MicroRNAs (miRNAs) are small non-coding RNAs that can posttranscriptionally regulate gene expression by targeting messenger RNAs. During miRNA biogenesis, the star strand (miRNA*) is generally degraded to a low level in the cells. However, certain miRNA* express abundantly and can be recruited into the silencing complex to regulate gene expression. Most miRNAs function as suppressive regulators...
Yangjing Capsule (YC), an innovative Chinese medicine based on traditional prescription, promotes testosterone synthesis by upregulating the expression of steroidogenic enzymes. Nur77 as a nuclear receptor is known to regulate the expression of many steroid synthetases. This study aimed to explore the potential mechanisms by which YC regulates testosterone synthesis in Leydig cells. Real-time P...
This paper presents a novel technique for synthesis of speed-independent circuits. It is based on partial order representation of the state graph called STG-unfolding segment. The new method uses approximation technique to speed up the synthesis process. The method is illustrated on the basic implementation architecture. Experimental results demonstrating its efficiency are presented and discus...
