Complement C6 is one of five plasma proteins that are incorporated into the lytic terminal complement complex on lipid membranes (C5b-9m) upon activation of the complement cascade. Oligonucleotide probes derived from partial amino acid sequences of purified C6 were used to isolate cDNA clones from a human liver cDNA library. The complete polypeptide structure of mature C6 deduced from the cDNA ...

C6-aldehydes are synthesized via lipoxygenase/hydroperoxide lyase action on polyunsaturated fatty acid (PUFA) substrates in plant leaves. The source pools and subcellular location of the processes are unknown. A close relationship is found between the composition of PUFA and the composition of C6-aldehydes. In the current study, this relationship was tested using the Arabidopsis PUFA mutant lin...

OBJECTIVE To study the effects and associated mechanisms of caffeine on cell viability, cycle dynamics, proliferation and apoptosis both in glioblastoma C6 and U87MG cells. MATERIALS AND METHODS Cell livability in presence or absence of caffeine was detected by the methyl thiazolyl tetrazolium (MTT) colorimetric assay. Flow cytometric analysis was conducted to investigate the cell cycle dynam...

Insulin-like growth factor-i (IGF-1) and IGF-2 are critical regulators of cell proliferation. The growth-promoting action of both ligands is mediated by the type 1 IGF receptor (IGF-1R). We have investigated the role of the IGF-1R in the growth and tumorigenicity of rat C6 glioblas toma cells. For this purpose, antisense RNA to IGF-1R RNA was intro duced into cells by either the addition of oli...

The study assessed the effect of Chinese herbs of Shenghe Powder (SHP) on the repair capacity of gamma-radiation-induced DNA damage in rat glioma cells (C6) compared with normal human astrocytes (NHA). C6 and NHA Cells treated with SHP and irradiated with 2Gy of gamma radiation. Cells growth inhibition were analysed by MTT assay, DNA damage and repair were evaluated using phosphorylated histone...

A recombinant adenovirus vector bearing the IL-4 gene (AD-IL-4) was used to infect rat glioma C6 cells in culture at multiplicity of infections (MOI) from 50 to 1800. C6 cell proliferation was not altered significantly by adenoviral infection. However, IL-4 production increased in a dose-dependent manner. To ascertain effects on in vivo cell proliferation, a subcutaneous tumor model was used. R...

A case of total spondyloptosis of the cervical spine at C6-7 level with cord compression is described in a 51-year-old male. Because the bodies of C6 and 7 were tightly locked together, cervical traction failed. Then the patient was operated on by a posterior approach. Posterior stabilization and fusion were performed by C4-5 lateral mass and C7-T1 pedicle screw fixation and rod instrumentation...

A MHC6 complex of a platinum group metal with a capped octahedral arrangement of donor atoms around the metal center has been characterized. This osmium compound OsH{κ(2) -C,C-(PhBIm-C6 H4 )}3 , which reacts with HBF4 to afford the 14 e(-) species [Os{κ(2) -C,C-(PhBIm-C6 H4 )}(Ph2 BIm)2 ]BF4 stabilized by two agostic interactions, has been obtained by reaction of OsH6 (PiPr3 )2 with N,N'-diphen...

objective(s):pharmacological studies showed that the extracts of jin yin hua and its active constituents have lipid lowering, antipyretic, hepatoprotective, cytoprotective, antimicrobial, antibiotic, antioxidative, antiviral, and anti-inflammatory effects. the purpose of the present study was to investigate the protective effects of caffeoylquinic acids (cqas) from jin yin hua against hydrogen ...

BACKGROUND In a previous study we found that intracerebral infusion of argatroban, a specific thrombin inhibitor, reduces brain edema and neurologic deficits in a C6 glioma model. OBJECTIVES To examine the role of thrombin in gliomas and whether systemic argatroban administration can reduce glioma mass and neurologic deficits and extend survival time in C6 and F98 gliomas. METHODS The prese...
