Cyclin D1 is an important cell cycle regulator but in cancer its overexpression also increases cellular migration mediated by p27 stabilization and RhoA inhibition. Recently, a common polymorphism at the exon 4-intron 4 boundary of the human cyclin D1 gene within a splice donor region was associated with an altered risk of developing cancer. Altered RNA splicing caused by this polymorphism give...
The receptors of the dopamine neurotransmitter belong to two unrelated classes named D1 and D2. For the D1 receptor class, only two subtypes are found in mammals, the D1A and D1B, receptors, whereas additional subtypes, named D1C, D1D, and D1X, have been found in other vertebrate species. Here, we analyzed molecular phylogeny, gene synteny, and gene expression pattern of the D1 receptor subtype...
Successive single day transfers of pot-grown wheat to high temperature (35/30°C day/night) replicated controlled environments, from the second node detectable to the milky-ripe growth stages, provides the strongest available evidence that the fertility of wheat can be highly vulnerable to heat stress during two discrete peak periods of susceptibility: early booting [decimal growth stage (GS) 41...
It has been well documented that dwarfing genes Rht-B1b and Rht-D1b are associated with Type I susceptibility to Fusarium head blight (FHB) in wheat; but the underlying mechanism has not been well delineated. Anther extrusion (AE) has also been related to Type I resistance for initial FHB infection, where high AE renders FHB resistance. In this study, two doubled haploid populations were used t...
Purpose: Alternative CCND1 splicing results in cyclin D1b, which has specialized, protumorigenic functions in prostate not shared by the cyclin D1a (full length) isoform. Here, the frequency, tumor relevance, and mechanisms controlling cyclin D1b were challenged. Experimental Design: First, relative expression of both cyclin D1 isoforms was determined in prostate adenocarcinomas. Second, releva...
سختی دانه یکی از مهم ترین خصوصیات کیفی گندم نان است که به وسیله آن طبقه بندی تجاری و نوع فرآورده نهایی تعیین می گردد. این صفت به وسیله دو ژن کاملاً پیوسته پوروایندولین a و پوروایندولین b کنترل می شود. آلل های نوع وحشی این دو مکان ژنی موجب فنوتیپ بافت دانه نرم می شوند و بروز جهش در هر یک از این دو مکان ژنی باعث سخت شدن بافت دانه می گردد. به دلیل اهمیت این صفت، 61 رقم تجاری و 92 توده بومی خالص ایر...
We used staining of tissue sections by lectin conjugates to screen inbred strains of mice for polymorphisms which could be used as histological markers of chimaerism. We found one polymorphism, which involves reciprocal patterns of expression of binding sites for the N-acetyl-galactosamine-binding lectins from Dolichos biflorus (DBA), Helix pomatia (HPA) and Wisteria floribunda (WFA) on intesti...
Grain hardness is the main factor for classification and end-use quality of wheat. Wheat with the hard grain texture has higher protein content and more intensive gluten that leads to production of higher bread quality. However, soft texture wheat has lower protein content and weaker gluten, which are suitable for cake and candy production. Grain hardness is determined by the Pina and Pinb gene...
Yan, Zhen, Wen-Jie Song, and D. James Surmeier. D2 dopamine dopamine (DA) (DeBoer et al. 1993; Di Chiara et al. 1994; receptors reduce N-type Ca currents in rat neostriatal cholinergic Lehman and Langer 1983; Stoof et al. 1982), it is unclear interneurons through a membrane-delimited, protein-kinase-C-insenhow this is accomplished. sitive pathway. J. Neurophysiol. 77: 1003–1015, 1997. Dopamine ...
Both dopamine D1-like (D1A and D1B) and D2-like (D2, D3, and D4) receptor subfamilies are present in the kidney. Blockade of the intrarenal D1-like receptor family is associated with natriuresis and diuresis. Because the D1A and D1B receptor subtypes are not distinguishable by currently available dopaminergic agents, their functional role remains undefined. In the present study, the effect of s...
