Overexpression of YKL40,IL-6, IL-8, TNF-α in tonsils and the role of YKL40 in childhood with obstructive sleep apnea syndrome
Abstract To evaluate the levels of YKL40, IL-6(interleukin-6), IL-8(interleukin-8), IL-10(interleukin-10), TNF-α (tumor necrosis factor-α) in OSAS (obstructive sleep apnea syndrome)children and explore the mechanism of YKL40 promoting inflammatory factors overexpression in tonsils. qPCR and ELISA we...

| Summary: | Abstract To evaluate the levels of YKL40, IL-6(interleukin-6), IL-8(interleukin-8), IL-10(interleukin-10), TNF-α (tumor necrosis factor-α) in OSAS (obstructive sleep apnea syndrome)children and explore the mechanism of YKL40 promoting inflammatory factors overexpression in tonsils. qPCR and ELISA were used to identify the expression of YKL40, IL-6, IL-8, IL-10, and TNF-α in the tonsils of OSAS children. Primary tonsil lymphocytes (PTLCs) were cultured and recombinant human YKL40(rhYKL40)was used to stimulate PTLCs in different concentrations and at different time points. The activation of NF-κB in PTLCs was screened by western blotting. Relative mRNA of YKL40, IL-6, IL-8, TNF-α was over expressed in OSAS-derived tonsil tissue and the levels of YKL40, IL-6, IL-8, and TNF-α was increased in OSAS-derived protein supernatant of tonsil tissue.The relative mRNA expression of IL-6, IL-8 and TNF-α increased under the treatment of YKL40 (100 ng/mmol for 24 h). The phosphorylation of p65 in NF-κB pathway was stimulated in the process. The levels of YKL40, IL-6, IL-8, and TNF-α increases in OSAS children, and YKL40 promotes the overexpression of IL-6, IL-8 and TNF-α in PTLCs via NF-κB pathway. The result implements that inflammation may play an important role in the pathogenesis of OSAS in children. |
