Changes in the NF-κB signaling pathway in juvenile and adult patients with Kashin-Beck disease

Exp Cell Res. 2019 Jun 15;379(2):140-149. doi: 10.1016/j.yexcr.2019.04.001. Epub 2019 Apr 2.


To investigate the pathogenesis of Kashin-Beck disease (KBD), we compared the common signaling pathways in peripheral blood mononuclear cells (PBMCs) obtained from healthy juvenile and adults and KBD patients, and also from osteoarthritis (OA) patients. The PBMCs from 12 KBD and 12 healthy juvenile, and those from 20 adult KBD patients and 12 healthy donors were separately collected among the people living in the KBD endemic area. The patients were distinguished according to the national diagnosis criteria. Total RNAs were extracted for the determination of gene expressions by microarray analysis. Ingenuity Pathways Analysis (IPA) was employed to identify the signaling pathways significantly affected by juveniles' and adults' KBD, and OA. The expressions of NFκB-p65, cIAP2 and RANKL in the articular cartilage from both juvenile and adults were detected by immunohistochemistry. NF-κB signaling, apoptosis signaling, death receptor signaling and IL-6 signaling pathways were revealed to be the common affected signaling pathways in the juvenile and adult KBD and the OA. BIRC3 and EGR1 were identified as two common differentially expressed genes. The percentages of positive staining of NFκB-p65, cIAP2 and RANKL were reduced in adult KBD patients but significantly increased in juvenile KBD patients. NF-κB, one of the common signaling pathways between adult and juvenile KBD, was less prominent in the adult KBD patients.
