FKN Facilitates HK-2 Cell EMT and Tubulointerstitial Lesions via the Wnt/ β-Catenin Pathway in a Murine Model of Lupus Nephritis
In this study, we therefore examined whether FKN could stimulate the process of EMT, NF-kB, TGFβ, CCL22, F4/80, inflammation, and tubulointerstitial fibrosis in a murine model of LN. We also determined whether FKN was involved in the EMT process of Wnt/β-catenin-expressing HK-2 cells. Mechanistically, we ascertained, for the first time, whether FKN up-regulated EMT-related gene signatures (e.g., vimentin, α-SMA), and hence, renal tubulointerstitial fibrogenesis, and the role of the Wnt/β-catenin signaling pathway in this process. Materials and Methods Cell Culture, Stable Infection, and Gr...

Decrease of GSK3 β Ser-9 Phosphorylation Induced Osteoblast Apoptosis in Rat Osteoarthritis Model
AbstractNowadays, the cumulative intake of glucocorticoids has become the most common pathogenic factor for non-traumatic osteonecrosis of the femoral head (ONFH). Apoptosis of osteoblasts is considered as the main reason of ONFH at the molecular level. Glycogen synthase kinase 3 β (GSK3β) is an important regulator of cellular differentiation and apoptosis pathway, which can modulate the balance between osteoblasts and osteoclasts. Several studies have reported about its function in osteoporosis, but little is known about it in osteonecrosis. In our study, lipopolysacchari de and methylprednisolone were utilized to estab...
