Three main inflammatory signaling pathways include nuclear factor-κB (NF-κB), Janus kinases/Signal transducer and activator of transcriptions (JAKs/STATs), and mitogenactivated protein kinases (MAPKs) play crucial roles in inducing, promoting, and regulating inflammatory responses in the immune system. Importantly, the breakdown of mechanisms that tightly regulate inflammatory signaling pathways can be the underlying cause of uncontrolled inflammatory responses and be associated with the generation and development of several inflammatory diseases. Hence, therapeutic strategies targeting inflammatory signaling pathways and their downstream components may promise to treat inflammatory diseases. Studies over the past two decades have provided important information on the polytrophic pharmacological and biochemical properties of berberine (BBR) as a naturally occurring compound, such as antioxidant, antitumor, antimicrobial, and antiinflammatory activates. Interestingly, the modulatory effects of BBR on inflammatory signaling cascades, which lead to the
Periodontal disease is a common chronic inflammatory disease of the oral cavity. This disease occurs as a consequence of uncontrolled inflammatory immune responses against periodontopathic bacteria. Several studies have documented the proinflammatory roles of the Signal Transducer and Activator of Transcription 1 (STAT1) and Wnt5a in inflammatory diseases. However, there has been no detailed investigation of STAT1 and Wnt5a genes expression in periodontal disease. So, we aimed to evaluate the expressions of STAT1 and Wnt5a in patients with chronic and aggressive periodontitis and determine their correlation with clinical parameters. Three groups of subjects were enrolled including control (20 healthy individuals), chronic (25 patients), and aggressive periodontitis patients (25 patients). The expressions of STAT1 and Wnt5a were evaluated in gingival tissue samples using a Real‐time polymerase chain reactions assay. The expressions of STAT1 and Wnt5a were significantly upregulated in chronic and aggressive periodontitis compared with the healthy control. We also found that the expressions of STAT1 and Wnt5a increased in aggressive periodontitis compared with chronic periodontitis. In addition, there was the linear relationship between the expression of STAT1 and Wnt5a and the clinical parameters, including clinical attachment loss and periodontal pocket depth. A linear relationship between the expressions of Wnt5a and the clinical parameters was also identified. Taken together, our findings highlight the roles of STAT1 and Wnt5a in the pathogenesis of the periodontal inflammation, suggesting these molecules as valuable therapeutic targets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
