[Retracted] Allium cepa L. and Quercetin Inhibit RANKL/Porphyromonas gingivalis LPS-Induced Osteoclastogenesis by Downregulating NF-κB Signaling Pathway

Table 1

AcE and Qt affect cytokine production during osteoclastogenesis and osteoclast activity. The supernatant was collected and IL-1α, IL-6, TNF, IL-3, and IL-4 levels were measured during osteoclastogenesis (24 hours, 3 days, and 5 days) and osteoclast activity (24 hours).
