    BIOCELL, Vol.48, No.2, pp. 283-291, 2024, DOI:10.32604/biocell.2023.045429 - 23 February 2024

    Abstract Background: α7 nicotinic acetylcholine receptor (α7nAChR) has been demonstrated to be involved in numerous of inflammatory diseases. Cell pyroptosis is a kind of cell death accompanied by inflammation. Objectives: The objective of this work is to explore the function of α7nAChR on cell pyroptosis in cervical cancer cells. Methods: Immunoblotting, quantitative polymerase chain reaction, and enzyme-linked immunosorbent assay were employed to examine the function of α7nAChR on cell pyroptosis and metabolic changes. Results: Herein, we found that α7nAChR inhibition led to cell pyroptosis in HeLa and SiHa of cervical cancer cells, which was attributed to the… More >

    European Cytokine Network, Vol.30, No.2, pp. 59-66, 2019, DOI:10.1684/ ecn.2019.0426

    Abstract Background: Recent studies have demonstrated that nicotine exhibited anti-inflammatory and neuroprotective properties by interacting with the alpha 7 nicotinic acetylcholine receptor (α7nAChR). However, the role of nicotine in regeneration during peripheral nerve injury has not been elucidated. The aim of this study was to investigate whether nicotine down-regulated production of proinflammatory cytokines and promoted peripheral nerve regeneration in rats. Methods: Rats challenged with sciatic nerve crush injury were treated with nicotine (1.5 mg/kg), three times per day. The expression of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α) and interleukin (IL-1β), pinch test results, growth-associated… More >
