ABSTRACT
Objective:
To observe the expression characteristics and co-localization of exogenous TRIM22 and HIV capsid protein p24 in glioma cells.Methods:
The vectors of pEGFP-N3-TRIM22 or pDsRed1-p24 were transfected into U-251 glioma cells respectively to examine the expression of TRIM22-EGFP or p24-DsRed1 by confocal microscopy. Moreover, we used a confocal z-stacking program to achieve series of optical sections and to rebuild 3-D images by ImageJ 1.50i software to detect the expression characteristics of p24-DsRed1 in U-251 cells. In the end, the vectors of pEGFP-N3-TRIM22 and pDsRed1-p24 were co-transfected into U-251 cells to detect the co-localization between TRIM22 and p24 by confocal microscopy.Results:
Confocal microscopy results showed that TRIM22-EGFP or p24-Dsred1 was localized to the cell body as well as to protuberance in U-251 cells, and 3D structural reconstruction showed that p24-Dsred1 could be transferred to foot processes of U-251 cells. Simultaneously, confocal microscopy results also showed that TRIM22 and p24 could be co-localized and their combination could be released by budding in U-251 cells co-transfected with pEGFP-N3-TRIM22 and pDsRed1-p24.Conclusion:
TRIM22 co-localized to HIV capsid protein p24 and their combination can be released by budding in glioma cells.
