Objective:
To study the expression of protein kinase C (PKC) alpha subtype in Chinese hamster ovary (CHO) cells.
Methods:
The PKC alpha primer pairs were designed based on the GenBank sequence of PKC alpha of a species with the highest homology to Chinese hamster identified using EMBL Data Library Clustalw tool. The sequence coding for PKC alpha, amplified from the CHO cells using RT-PCR, was ligated to the pGEM-T plasmid vector, and the recombinant vector was transformed into E.coli DH5alpha with the positive colones selected by blue/white screening. Restriction enzyme digestion, gel electrophoresis analysis, followed by sequencing of the digestion products were performed for identification of the recombinant. Western blotting was used to analyze the PKC alpha expression in the CHO cells.
Results:
The presence of PKC alpha mRNA was detected in the CHO cells by RT-PCR. Western blotting also identified PKC alpha expression in the cells.
Conclusions:
PKC alpha expression has been identified in the CHO cells, which may facilitate further structural and functional study of PKC alpha and investigation of its role in the intracellular signal transduction pathways.
