Grape, having considerable sources of phenolic substances, such as anthocyanin and flonoids, is an important fruit. On the other hand, the amount of these substances and antioxidant activity in fruits of grape cultivars varies in different growing conditions. Antioxidants are the first line of body defense against free radicals and are critical for human health. To determine antioxidant activit...
kuh-e-siah is located in the north of gavkhuni lagoon and east of the varzaneh (se of isfahan) and is a part of urumieh-dokhtar magmatic arc (udma). the volcanic rocks of this area are vesicular basalt and basaltic andesite with late miocene age. the most common textures of these rocks are porphyry, microlitic porphyritic, hyaloporphyric and vesicular. plagioclase, olivine and clinopyroxene are...
Siah-Kamar hornfalses and skarns are located about 5Km east of Dehsalm and 85Km west of Nehbandan city, southeast of Birjand Province and east of Lut Block. This Skarn formed by injected Rigi granitoid (Eocene age) into limestone and sandstone (Upper Cratacious). Rigi Mountain is mainly granodiorite in composition and contains plagioclase, quartz, hornbelend and biotite minerals. Geochemistry ...
T-STAR is one of three members of the SAM68 family of RNA-binding proteins that have been shown to be involved in various gene expression pathways including the control of pre-mRNA splicing. We employed a two-hybrid screen to identify proteins that interact with human T-STAR. The predominant interacting proteins were the E3 ubiquitin ligases SIAH1 and SIAH2. We found that SIAH1 bound to an octa...
Abnormal accumulation of beta-catenin is considered to be a strong driving force in hepatocellular carcinogenesis; however, the mechanism of beta-catenin accumulation in tumours is unclear. Here, it was demonstrated that hepatitis B virus X protein (HBx) differentially regulates the level of beta-catenin through two ubiquitin-dependent proteasome pathways depending on p53 status. In the presenc...
