From: HLA-C increases HIV-1 infectivity and is associated with gp120
Specific silencing of HLA-C in human cell lines. Panel A: off-target effect analysis by RT-PCR in HLA-C silenced (+) and non-silenced (-) HeLa cells expressing HIV-1 gp120/gp41 (ADA). PCR was performed with primers specific for HLA (A, B, C), gp120, β2-microglobulin and GAPDH. M: molecular weight marker. No off-target effect due to HLA-C mRNA silencing is affecting the mRNA levels of the other MHC class I genes, as well as β2-microglobulin, HIV-1 gp120 or the housekeeping control gene GAPDH. Panel B: western-blot analysis of HLA-C protein expression. After 72 hours from siRNAs transfection, HLA-C is undetectable both in HeLa-ADA and in 293T cells.
