RESUMO
AIM: Comprehensive study of the negative regulation components of cell signaling in the bronchial asthma (BA) patients with metabolic disorders. MATERIALS AND METHODS: 113 people were examined: 63 patients with allergic BA (ABA), 50 patients with a non-allergic variant of the disease (NABA). SOCS1 mRNA expression was evaluated by reverse transcription PCR (RT-PCR). SOCS1 protein expression was investigated by immunoblotting. The determination of cytokine levels was carried out according to the standard protocol on a Bio-Plex flow fluorimeter. RESULTS: A significant and multidirectional change in the expression of SOCS1 mRNA was found at a body mass index 25 (greater than normal) in ABA and NABA. The positive correlations between SOCS1 mRNA expression and body mass index indicate the regulatory role of SOCS1 in leptin signaling. The spectra of correlations in ABA and NABA are different, it indicates the probable existence of specificity in the pathogenesis of these variants of the diseases. CONCLUSION: The obtained data allow us to consider the complexity of regulation disorders occurring at different levels of cell signaling. The multifunctionality of the SOCS1 regulator provides complex control of cytokine signaling simultaneously in different signaling pathways in the BA with metabolic disorders.
