doi: 10.3390/v17081081
Figure Lengend Snippet: SOCS3 expression facilitates PCV2 replication. ( a ) Fluorescence imaging of PK-15 cells transfected with varying concentrations of Cy3-labeled siRNA. ( b ) SOCS3 mRNA expression levels and ( c ) corresponding knockdown efficiency at different time points post-siRNA transfection. ( d ) Fluorescence visualization of HEK-293T cells at distinct time intervals following lentiviral vector transduction. ( e ) Fluorescence patterns of SOCS3-stably transfected cells and blank controls after 10 consecutive passages. ( f ) Relative SOCS3 mRNA expression levels in stably transfected cells. ( g ) Cell viability analysis of SOCS3-silenced and overexpressing cell lines. ( h ) Protein expression profiles in SOCS3-knockdown and overexpression models. ( i ) Absolute quantitative PCR analysis of PCV2 viral copy numbers in wild-type PK-15, si-NC, and si-SOCS3-2 cells infected with PCV2 (MOI = 1) at indicated time points. ( j ) PCV2 viral load quantification in wild-type PK-15, PK-15-pCDH, and PK-15-SOCS3 cells post-infection. ( k ) Indirect immunofluorescence detection of PCV2 infection status across experimental groups. Data are presented as mean ± SD ( n = 3). *** p < 0.001 vs. control.
Article Snippet: Immunoblotting was performed using a rabbit polyclonal anti-SOCS3 antibody (Proteintech; 1:1000 dilution) incubated overnight at 4 °C, followed by incubation with a HRP-conjugated goat anti-rabbit secondary antibody (Servicebio; 1:3000 dilution) for 1 h at room temperature.
