Sinomenine facilitates the efficacy of gabapentin or ligustrazine hydrochloride in animal models of neuropathic pain.

Management of chronic pain is restricted by the lack of effective tools. This study evaluated the efficacies of sinomenine combined gabapentin or ligustrazine hydrochloride in treating peripheral and central chronic neuropathic pain. The study was conducted in mice with photochemically induced sciatic nerve injury, and in rats with photochemically induced spinal cord injury.

Gabapentin and NMDA receptor antagonists interacts synergistically to alleviate allodynia in two rat models of neuropathic pain.

Background and aims The clinical management of neuropathic pain remains a challenge. We examined the interaction between gabapentin and NMDA receptor antagonists dextromethrophan and MK-801 in alleviating neuropathic pain-like behaviors in rats after spinal cord or sciatic nerve injury. Methods Female and male rats were produced with Ischemic spinal cord injury and sciatic nerve injury.

Repeated sinomenine administration alleviates chronic neuropathic pain-like behaviours in rodents without producing tolerance.

Background and aims We have previously reported that systemic administration of sinomenine produced antinociception in various experimental pain conditions in rodents, particularly in models of neuropathic pain. In the present study we assessed the effects of repeated administration of sinomenine in two rodent models of neuropathic pain in order to study the development of tolerance. Methods The analgesic effect of sinomenine was tested in female Sprague-Dawley rats that exhibited mechanical and cold hypersensitivity following ischaemic injury to the spinal cord and in male C57/BL6 mice that developed mechanical hypersensitivity after ischaemic injury to the sciatic nerve.

Sinomenine alleviates mechanical hypersensitivity in mice with experimentally induced rheumatoid arthritis.

Background and aims We have previously reported that sinomenine, an alkaloid isolated from the root of the plant Sinomenium acutum, had antinociceptive effect in rodent models of acute inflammatory or neuropathic pain. As a traditional medicine, sinomenine is used in China to treat rheumatoid arthritis (RA). Methods In the present study, we evaluated the potential antinociceptive effect of sinomenine in a mouse model of RA, collagen type II antibody (CII Ab) induced arthritis (CAIA) after acute and chronic administration.

MicroRNA-145 inhibits lung cancer cell metastasis.

Previous studies have identified a variety of microRNAs (miRNAs) that have important roles in cancer progression, particularly in tumor invasion and metastasis. Downregulation of miR‑145 was reported to occur in various types of human cancer; however, the role of miR‑145 in lung cancer metastasis and its potential mechanisms of action remain to be elucidated. The present study aimed to investigate the effects of miR‑145 on metastasis and epithelial‑mesenchymal transition (EMT) in A549 human lung adenocarcinoma cells.

Octamer-binding protein 4 affects the cell biology and phenotypic transition of lung cancer cells involving β-catenin/E-cadherin complex degradation.

Clinical studies have reported evidence for the involvement of octamer‑binding protein 4 (Oct4) in the tumorigenicity and progression of lung cancer; however, the role of Oct4 in lung cancer cell biology in vitro and its mechanism of action remain to be elucidated. Mortality among lung cancer patients is more frequently due to metastasis rather than their primary tumors. Epithelial‑mesenchymal transition (EMT) is a prominent biological event for the induction of epithelial cancer metastasis.
