Abstract:


Background: The aim of the study was to evaluate the changes in the expression of genes - TNF-α, IFN-γ, depending on the time and concentration of IL-12 used to expose the Normal Human Dermal Fibroblast (NHDF) cells.

Methods: The material for the study included NHDF exposed to IL-12 in various IL-12 concentrations (1/10/100 ng/ml) and exposure time 0.5h, 1h, 2h, 4h, 8h, 24h, compared to the control. Changes in gene expression were evaluated with the use of the RTqPCR method. The statistical analysis was performed with the use of Statistica 12.5 PL The role of genes of the JAK-STAT signaling pathway in the induction of the inflammatory process was determined with the use of the PANTHER overrepresentation test.

Results: Regardless of the time of NHDF exposure and the IL-12 concentrations used, we observed changes in the expressions of TNF-α and IFN-γ. Increased expression of one transcript involves the decreased expression of the other. We assessed that genes of the JAK-STAT signaling pathway are engaged in 6 biological processes, 8 molecular functions, 6 signaling pathways.

Conclusion: The conducted studies indicate that conclusions about the intensity of the inflammatory process, and the efficacy of the anti-cytokine therapeutic strategy, may be made on the basis of the TNF-α, IFN-γ expression.
