Figure Lengend Snippet: Efficiency of transduction with the rAAV/DJ vector of the A375, G-361, SK-MEL-1, and CCD-1064Sk cells under hyperthermia. The results are shown for non-transduced cells (control) and transduced cells (rAAV/DJ) under standard conditions (37 °C) and underhyperthermia (43 °C). The results are presented as a mean of two independent experiments conducted in three repeats ± SD. The number of GFP+ (green fluorescent protein positive) cells was measured with an automatic cell counter ( A ) and a flow cytometer (FACS) ( B ). ( C ) The number of rAAV/DJ vector genome copies was measured in the analyzed cells with the qPCR method. Statistically significant differences between 37 °C and 43 °C are marked with asterisks (*** p < 0.001; **** p < 0.0001). ( D ) Cell viability after exposure to the hyperthermia condition. The results are presented as a percentage of live cells. The data were measured with FACS. Statistically significant differences between the number of live cells at 37 °C (control) and values in other conditions are marked with asterisks (* p < 0.05; ** p < 0.01).
Article Snippet: For cell transduction under hyperthermia conditions, the rAAV/DJ/CAG/GFP mosaic vector (rAAV/DJ; Cat. No. 7078; Vector Biolabs, Malvern, PA, USA) was used at the multiplicity of infection (MOI) of 4 × 10 4 gene copies.
