One cell model establishment to inhibit CaMKII γ mRNA expression in the dorsal root ganglion neuron by RNA interfere.

CaMKIIγ in dorsal root ganglion neurons is closely related to the neuropathic pain, neuron injury induced by local anesthetics. To get great insight into the function of CaMKIIγ in dorsal root ganglion neurons, we need one cell model to specially inhibit the CaMKIIγ mRNA expression. The present study was aimed to establish one cell model to specially inhibit the CaMKIIγ mRNA expression. We designed the CaMKIIγ shRNA sequence and connected with pYr-1.1 plasmid. The ligation product of the CaMKIIγ shRNA and pYr-1.1 plasmid was recombined with pAd/PL-DEST vector into pAD-CaMKIIγ-shRNA. adenovirus vector. pAD-CaMKIIγ-shRNA. adenovirus vector infected the dorsal root ganglion neuron to inhibit the CaMKIIγ mRNA expression in vitro. The pAD-CaMKIIγ-shRNA adenovirus vector was verified to be correct by the digestion, sequence. And pAD-CaMKIIγ-shRNA. adenovirus vector can infect the DRG cells to inhibit the CaMKIIγ mRNA or protein expression by the real-time polymerase chain reaction (PCR) or western blotting. Those results showed that we successfully constructed one adenovirus vector that can infect the dorsal root ganglion neuron to inhibit the CaMKIIγ mRNA and protein expression. That will supply with one cell model for the CaMKIIγ function study.
