Aim
To single out mRNA and microRNA genes relating to TNF-α signal paths, the expression of which could indicate sensitivity of cells to the medicine in question. Material and
Conclusions
It was ascertained that adalimumab has therapeutic potential and affects genes engaged in signal paths activated by TNF-α. The results indicate the TNF-α usefulness as the molecular, supplementary marker in diagnostics and control of treatment effects.
Material and methods
The material used in the research consisted in the cell line of regular human skin fibroblasts NHDF (CC-2511 Lonza, Basel, Switzerland) exposed to adalimumab with a concentration of 8.00 μg/ml of the medium for 2, 8 and 24 h, compared with the control material, i.e. non-stimulated cells. Molecular analysis was performed using the oligonucleotide expressive micro-matrices technology HG-U133A, miRNA 2.0 Array micro-matrices and RTqPCR.

The material used in the research consisted in the cell line of regular human skin fibroblasts NHDF (CC-2511 Lonza, Basel, Switzerland) exposed to adalimumab with a concentration of 8.00 μg/ml of the medium for 2, 8 and 24 h, compared with the control material, i.e. non-stimulated cells. Molecular analysis was performed using the oligonucleotide expressive micro-matrices technology HG-U133A, miRNA 2.0 Array micro-matrices and RTqPCR.
Results
mRNA: BIRC5, MAP3K4, ZFAND5, JUN differentiate cells exposed to the anti-TNF medicine, regardless of the time of cell/medicine incubation. TNF-α transcription activity is reduced during exposure of NHDF cells to adalimumab. miRNA regulating transcription activity of the said 4 mRNA and miRNA related to TNF-α and its receptors was also singled out. Conclusions: It was ascertained that adalimumab has therapeutic potential and affects genes engaged in signal paths activated by TNF-α. The results indicate the TNF-α usefulness as the molecular, supplementary marker in diagnostics and control of treatment effects.
