Key components of COPI and COPII machineries are required for chikungunya virus replication.

Abstract:

:The infection of CHIKV is associated with cellular membranes; however whether early secretory pathways are involved in CHIKV replication remains unclear. In the present study, we have provided initial evidences that CHIKV requires both COPI and COPII for its replication. Small interfering RNAs against COPI components, including coatomer, ARFs or GBF1, suppress CHIKV replication. Moreover, CHIKV infection is abolished by the presence of ARF1 inhibitor brefeldin A or GBF1 inhibitor golgicide A. In addition, perturbation of COPII by silencing key components of COPII pathways leads to a reduction in CHIKV replication. Collectively, these observations demonstrate the importance of functional secretory pathways in the infectivity of CHIKV.

  • Uniform amplification of multiple DNAs by emulsion PCR.

    abstract::When several DNAs are amplified by PCR in one PCR tube, biased amplification is known to occur because amplification efficiency differs from one DNA to another. Therefore, we conducted PCR in the water in oil-emulsion (W/O emulsion) to examine whether the procedure allows the uniform amplification of several DNAs. In ...
