OBJECTIVES To explore the correlation between expression patterns and functions of miR-383 and LDHA in hepatocellular cancer (HCC). MATERIALS AND METHODS We detected the expression of miR-383 and LDHA in 30 HCC tissues and their matched adjacent normal tissues using qRT-PCR. Then we performed MTT assay, foci formation assay, transwell migration assay, glucose uptake assay and lactate producti...

Bacillus coagulans has good potential as an industrial production organism for platform chemicals from renewable resources but has limited genetic tools available. Here, we present a targeted gene disruption system using the Cre-lox system, development of a LacZ reporter assay for monitoring gene transcription, and heterologous d-lactate dehydrogenase expression.

We have isolated a high-light and heat-shock inducible gene, Arabidopsis heat shock transcription factor (HsfA2), which induces expression of various types of target gene such as heat shock protein 18.2-CI (Hsp18.1-CI), galactinol synthase 1 (GolS1), and Bcl-2-associated athanogene 6 (Bag6). Here we investigated the regulatory system of target genes operating via HsfA2. A transient reporter ass...

Nkx3.1 is a prostate-specific homeobox gene related strongly to prostate development and prostate cancer. To study its regulation of transcription, 1.06 kb 5' flanking region of Nkx3.1 gene and its 5' deletion mutants (861, 617, 417 and 238 bp) were obtained by PCR and cloned into pGL(3)-basic, a promoter-less luciferase reporter vector, to examine their promoter activities driving the reporter...

Background: The magnetic nanoparticle-based transfection method is a relatively new technique for delivery of functional genes to target tissues. We aimed to evaluate the transfection efficiency of rat neural stem cell (NSC) using poly-L-lysine hydrobromide (PLL)-coated super paramagnetic iron oxide nanoparticles (SPION). Methods: The SPION was prepared and coated with PLL as transfection agent...

Malaria is a life-threatening human infectious disease transmitted by mosquitoes. Levels of the salivary gland sporozoites (sgs), the only mosquito stage infectious to a mammalian host, represent an important cumulative index of Plasmodium development within a mosquito. However, current techniques of sgs quantification are laborious and imprecise. Here, transgenic P. berghei reporter lines that...

The inhibitory effect of microRNA (miR)-325 in multiple different types cancer cell has been identified; however, its biological function T acute lymphoblastic leukemia (T-ALL) remains unknown. Moreover, Bcl-2-associated athanogene (BAG)2 is highly expressed a various tumors and regarded as an anti-apoptotic gene. In the present study, roles miR-325 BAG2 T-ALL line (Jurkat cells) were investiga...

Fibronectin/integrin-mediated signaling plays a key role in the regulation of adhesion, migration and metastasis of tumors. Numerous studies have addressed the significance of the association between integrin and RhoA, but the exact mechanism is unclear. Results from laboratories, including ours, have demonstrated that PKA inhibits the activity and function of RhoA. This study was designed to i...

BacMam viruses are modified baculoviruses that contain mammalian expression cassettes for viral gene delivery and transient expression in mammalian cells. They are easily, inexpensively, and rapidly generated and provide a versatile solution for G protein-coupled receptor (GPCR) cell-based assay development. Using BacMam technology, target gene expression levels are easily controlled and simult...
