Emticicia soli sp. nov., a novel member of the family 'Flexibacteraceae', isolated from tetrabromobisphenol A-contaminated soil.

Bacterial strain ZZ-4T, a Gram-stain-negative, aerobic, non-spore-forming, non-motile, non-flagellated, rod-shaped bacterium, was isolated from tetrabromobisphenol A-contaminated soil in PR China. The taxonomic position of this strain was investigated using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain ZZ-4T was a member of the genus Emticicia and showed the highest sequence similarity to Emticicia fontis IMCC1731T (98.

Terrimonas suqianensis sp. nov., isolated from a tetrabromobisphenol A-contaminated soil.

Strain C3-5, a Gram-negative, asporogenous, rod-shaped bacterium, was isolated from a tetrabromobisphenol A contaminated soil. Growth was observed at 10-37 °C (optimum 30 °C) and at pH 5.5-9.

Association between CLPTM1L-TERT rs401681 polymorphism and risk of pancreatic cancer: a meta-analysis.

Telomere biology plays a critical and complex role in the initiation and progression of cancer. Several recent studies have provided evidence that rs401681 polymorphisms in intronic region of cleft lip and palate trans-membrane 1-like (CLPTM1L) gene sequence are associated with pancreatic cancer (PC) development, but a comprehensive synopsis is not available. We performed a meta-analysis of 6 case-control studies that included 8,253 pancreatic cancer cases and 37,646 case-free controls.

[Role of Smad signaling in transcription of Smad7 gene mediated by TGF-beta1 in odontoblast cell line MDPC-23].

Purpose: To investigate the role of Smad signaling in transcription of Smad7 gene mediated by TGF-beta1 in odontoblast cell line MDPC-23, and to explore the molecular mechanism of Smad7 gene expression mediated by TGF-beta1 at the transcriptional level.

Methods: Smad function and its role in transcription of Smad7 were investigated in cotransfection experiments using Smad7 promoter-luciferase reporter construct containing the sequence between -408 bp and +112 bp of mouse Smad7 gene. The data were analysed by one-way ANOVA.

[Antitumor immune responses induced by gene transfer of 4-1BBL into hepatocellular carcinoma Hepa1-6 in vitro].

Objective: To study the cytotoxic activity against tumor cells and cytokines production of spleen cells induced in vitro by murine 4-1BBL gene transfected Hepa1-6.

Methods: The eukaryotic expression vector pCDNA3.1(+)-m4-1BBL was transfected into murine hepatocellular carcinoma cell line Hepa1-6 by Liposomes.

[Cloning, expression and antitumor effect of mouse costimulatory molecule 4-1BBL].

Aim: To clone mouse 4-1BBL gene, construct its eukaryotic expression vector, and evaluate antitumor activity of the expression product.

Methods: RT-PCR was used to amplify mouse 4-1BBL gene from total RNA of C57BL/6 splenocytes stimulated by PHA. Then m4-1BBL cDNA was subcloned into eukaryotic expression vector pcDNA3.
