Multisubunit RNA polymerases IV and V (Pol IV and Pol V) evolved as specialized forms of Pol II that mediate RNA-directed DNA methylation (RdDM) and transcriptional silencing of transposons, viruses, and endogenous repeats in plants. Among the subunits common to Arabidopsis thaliana Pols II, IV, and V are 93% identical alternative ninth subunits, NRP(B/D/E)9a and NRP(B/D/E)9b. The 9a and 9b sub...
Introduction: Natural biomaterials and growth factors are key factors in tissue engineering. The objective of the present study was to evaluate transforming growth factor beta 1 (TGF-β1) and curcumin on proliferation and differentiation of nasal-derived chondrocyte seeded on the fibrin glue scaffold. Methods: Chondrocytes were isolated from nasal samples. Nasal-derived chon...
هدف: عامل رشدی تمایزی 9b عامل رشد پروتئینی مشتق از تخمک است که بیان آن در تکوین فولیکولهای تخمدان ضروری است. این عامل بهواسطه گیرنده خود که بر سطح سلول های گرانولوزا قرار دارد اثر خود را اعمال می کند. اثر عامل رشدی تمایزی 9b بر رشد فولیکول های مراحل مختلف تکوینی بهویژه فولیکول های بدوی و اولیه نامشخص است. هدف از این مطالعه بررسی اثر عامل رشدی تمایزی 9b بر رشد فولیکولهای مراحل مختلف تکوی...
Alternatively spliced isoforms of certain apoptosis regulators, such as Bcl-x, Ced-4, and Ich-1, have been shown to play opposing roles in regulating apoptosis. Here, we describe the identification of an endogenous alternatively spliced isoform of caspase-9, named caspase-9b, which lacks the central large subunit caspase domain. Caspase-9b is detectable in many cell lines by PCR and at the mRNA...
Two independent gain-of-function point mutations (S252W and P253R) in the extracellular region of the FGFR2 (fibroblast growth factor receptor 2) increase the binding affinity for the growth factor. The effect of this enhanced growth factor binding by these mutants is expected to be an increase in activation of regular signalling pathways from FGFR2 as a result of more receptors being engaged b...
