چکیده

In traditional Chinese medicine, Fuzi is widely used as an antitumor agent or an adjuvant medication combined with radiotherapy and chemotherapy, but its mechanism remains unclear. In this study, we investigated anti-tumor and immunoregulation efficacy of Fuzi combined with radiotherapy in mice with Lewis lung cancer (LLC). We found that Fuzi combined with radiotherapy significantly inhibited the growth of LLC, promoted the apoptosis of cancer cells, and prolonged the survival of mice with LLC. Mechanistically, we found that Fuzi decreased the proportion of Treg cells, reduced serum levels of cytokines such as interleukin (IL)-10 and transforming growth factor (TGF)-β, and downregulated the expression of programmed death ligand-1 in mice with LLC subjected to radiotherapy. This study suggests that Fuzi has immunomodulation function to act as radiosensitizer and improve radiotherapy against lung cancer.

The effect of melatonin on Superoxide dismutase and Glutathione peroxidase activity, and Malondialdehyde levels in the targeted and the non-targeted lung and heart tissues after irradiation in xenograft mice colon cancer

Introduction: Introduction: Radiation causes damage to irradiated tissues and also tissues that do not receive direct irradiation through a phenomenon called bystander effects. Melatonin as a potent antioxidant and anti-inflammatory agent is known for protection of normal tissues against ionizing irradiation. In addition, some studies have suggested that Melatonin may have some...

Analgecine enhances the anti-tumor response of radiotherapy by increasing apoptosis and cell cycle arrest in non-small cell lung cancer

We investigated whether Analgecine treatment enhanced the antitumor response of radiotherapy in non-small cell lung cancer (NSCLC) cells. Lewis lung carcinoma (LLC) xenograft mice treated with Analgecine plus irradiation showed reduced tumor growth and increased survival. Tumor cell apoptosis was enhanced by Analgecine, based on TUNEL assays. It also increased plasma levels of pro-inflammatory ...
