Herbal medicine can present an alternative way of treating liver cancer. Here, we explored a matrine- and sophoridine-containing herbal compound medicine (AH-05) extracted from Adenophora capillaris, Sophora flavescens, Astragalus, and other plants. H22 and HepG2 cell models, as well as an H22 xenograft model, were established. Cell proliferation and apoptosis were measured in vitro, and tumor volume and weight were observed in vivo. The activation of AKT/mTOR and nuclear factor-κB (NF-κB) pathways in tumor cells and the polarization of CD4/CD8 T cells in the spleen were tested. To assess safety, hematological toxicity and pathology of the liver, kidney, spleen, and intestine were evaluated. AH-05 inhibited cell viability in a dose- and time-dependent manner. In vivo, tumor volume and weight were reduced, and the activation of NF-κB p50, NF-κB p65, AKT, p-AKT Ser473, and mTOR was suppressed. In addition, AH-05 promoted CD4+ T cell polarization in the spleen. With regard to safety, slight intestinal mucosa edema was observed, but no severe pathological or hematological toxicity was detected. AH-05 exhibited its therapeutic effects against liver cancer by regulating the AKT/mTOR and NF-κB signaling pathways, and the immune environment, by promoting CD4+ T cell polarization in the spleen. Thus, AH-05 represents a potential supplementary herbal compound medicine for liver cancer.

Abstract Besides being mandatory in the metabolic system, adipokines like leptin directly affect immunity. Leptin was found to be necessary in T helper 1 (Th1)-dependent inflammatory processes, whereas effects on Th2 cells are rarely understood. Here, we focused on leptin in T-helper cell polarization and in Th2-mediated intestinal inflammation in vivo. The induction of cytokine-producing Th1 or Th2 cells from naive CD4+ T cells under polarizing conditions in vitro was generally decreased in cells from leptin-deficient ob/ob mice compared with wild-type mice. To explore the in vivo relevance of leptin in Th2-mediated inflammation, the model of oxazolone-induced colitis was employed in wild-type, ob/ob, and leptin-reconstituted ob/ob mice. Ob/ob mice were protected, whereas wild-type and leptin-reconstituted ob/ob mice developed colitis. The disease severity went in parallel with local production of the Th2 cytokine IL-13. A possible explanation for the protection of ob/ob mice in Th1- as well as in Th2-dependent inflammation is provided by a decreased expression of the key transcription factors for Th1 and Th2 polarization, T-bet and GATA-3, in naive ob/ob T cells. In conclusion, these results support the regulatory function of the adipokine leptin within T-cell polarization and thus in the acquired immune system and support the concept that there is a close interaction with the endocrine system.
