The objective of this paper was to investigate the inhibitory effect of total flavonoids from Pteris multifida Poir on growth of transplanted H22 tumour in mice. H22 tumour-bearing mice model was established; the experimental animals were divide/d into the model group, Pteris multifida Poir total flavonoids high-, low-dose groups, and CTX group. Pteris multifida Poir groups were administered co...
It remains a substantial challenge to targetedly deliver drug to both primary tumors and metastatic lesions employing a single nanoparticle delivery system. Here aiming at the receptor for hyaluronic acid mediated motility (RHAMM or CD168), a specific receptor for hyaluronic acid (HA), the bioreductive responsive HA nanogels loaded doxorubicin were prepared. The targeting effects of HA nanogels...
The role of autophagy in cancer is controversial. Melatonin has been linked to several aspects of cancer progression and also to regulation of autophagy. Whether melatonin is involved in an autophagy-induced tumor suppressor mechanism or a cyto-protective mechanism is unknown. Therefore, we investigated the effects of melatonin on autophagy and its upstream regulator. We found that melatonin tr...
Fc gamma receptor I (FcγRI, CD64) is a well-known target antigen for passive immunotherapy against acute myeloid leukemia and chronic myelomonocytic leukemia. We recently reported the preclinical immunotherapeutic potential of microtubule associated protein tau (MAP) against a variety of cancer types including breast carcinoma and Hodgkin's lymphoma. Here we demonstrate that the CD64-directed h...
The purpose of this study was to investigate the effect of astragalus polysaccharides (APSs), active constituents of astragalus, in the treatment of hepatocellular carcinoma (HCC) and their potential as a promising candidate for future anticancer drug development. Astragalus polysaccharide was administered at different doses to HCC H22-bearing mice to investigate their antitumor effects. Result...
Glutathione peroxidase (GPx) is an antioxidant protein containing selenium. Owing to the limitations of native GPx, considerable efforts have been made to develop GPx mimics. Here, a short 5-mer peptides (5P) was synthesized and characterized using matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Enzyme coupled assays were used to evaluate GPx activity. The cell via...
Cardiac glycosides could increase intracellular Ca2+ ion by inhibiting the Na+/K+ATPase to induce apoptosis in many tumor cells. However, narrow therapeutic index, poor tumor selectivity and severe cardiovascular toxicity hinder their applications in cancer treatment. To improve the safety profile and tumor targetablility of cardiac glycosides, we designed octreotide conjugated periplocymarin, ...
OBJECTIVE To investigate the effects of Scutellaria barbata extract (ESB) in suppressing tumor growth and modulating the immune functions in mice bearing tumors derived from hepatocarcinoma H22 cells. METHODS Fifty mice inoculated subcutaneously with H22 cells were equally divided into the model group, high-, moderate-, and low-dose ESB groups, and 5-Fu group, with corresponding treatments fo...
Celecoxib is a potent nonsteroidal anti-inflammatory drug that has demonstrated promise in cancer chemoprevention and treatment. The present study was conducted to gain insight into the molecular mechanism by which celecoxib induces apoptosis in the H22 mouse hepatoma cell line. The effect of celecoxib on the viability of H22 mouse hepatoma cells was assessed with sulforhodamine B assay. Apopto...
Purpose: To investigate the immunomodulatory and antitumor activities of ligustilide (LIG) extracted from Angelica sinensis in mice. Methods: Normal and tumor-bearing Institute of Cancer Research (ICR) mice were treated p.o. with LIG (5, 20 and 80 mg/kg/day) for 7 days. In normal ICR mice, phagocytosis of peritoneal macrophages and serum hemolysin concentration were assessed by chicken red bloo...
