ABSTRACT
Sterol C24-methyltransferase (SMT) plays multiple important roles in plant growth and development. SMT1, which belongs to the family of transferases and transforms cycloartenol into 24-methylene cycloartenol, is involved in the biosynthesis of 24-methyl sterols. Here, we report the cloning and characterization of a cDNA encoding a sterol C24-methyltransferase from().(GenBank access number KU885950) is a 1530 bp cDNA with a 1041 bp open reading frame predicted to encode a 346-amino acid, 38.62 kDa protein. The polypeptide encoded by thecDNA was expressed and purified as a recombinant protein from() and showed SMT activity. The expression ofwas highly up-regulated incell suspension cultures treated with methyl jasmonate (MeJA). Tissue expression pattern analysis showed higher expression in the phellem layer compared to the other four organs (leaf, stem, xylem and phloem), which is about ten times that of the lowest expression in leaf. The results are meaningful for the study of sterol biosynthesis ofand will further lay the foundations for the research in regulating both the content of other main compounds and growth and development of
ABSTRACT
Objective To observe the effect of treating Diabetic Peripheral Neuropathy with Acupoint Injection. Methods 65 patient with DPN were randomly recruited into a control group and a treatment group after adjusting stage. The control group was treated with acupuncture, while the treatment group was treated with the Safflower inoculation fluid acupuncture point injects. Nerve function parameter (MDNS、 NCV) and clinical symptoms were observed after 3 therapeutic courses. Results Nerve function parameter (MDNS、 NCV) and clinical symptoms in the treatment group were apparently improved after treatment (P<0.05) . Conclusion Acupuncture point injected with Safflower inoculation fluid may improve clinical symptoms and nerve functions of DPN patients.
