background and objective: chlorella vulgaris is a multi-cellular edible algal species with abundant proteins. extraction of high value protein fractions for pharmaceutical and nutritional applications can significantly increase the commercial value of microalga biomasses. there is no known report on the anticancer peptides derived from the chlorella vulgaris abundant protein. materials and meth...

BACKGROUND Interleukin-24(IL-24), also referred to as melanoma differentiation-associated gene-7(mda-7), is a unique member of the IL-10 gene family, which displays nearly ubiquitous cancer-specific toxicity. The most notable feature of IL-24 is selectively induced growth suppression and apoptosis in various cancer cells, with no harmful effects toward normal cells. Autophagy is a self-protecti...

Lung cancer is the leading cause of cancer deaths in both men and women in the United States accounting for about 27% of all cancer deceases. In our effort to develop newer therapy for lung cancer, we evaluated the combinatory antitumor effect of siRNA targeting VEGF and the PI3K/mTOR dual inhibitor PF-04691502. We analyzed the anticancer effect of siRNA VEGF and PF-04691502 combination on prol...

The combined effect of human lymphoblastoid interferon (HLBI) and anticancer agents on the growth of MOLT-4 was studied in vitro. The interferon showed a strikingly synergistic interaction in combination with aclarubicin, cytosine arabinoside or prednisolone. It was moderately synergistic in combination with adriamycin or 5-fluorouracil and tended to show additive effects with daunorubicin or v...

Although erlotinib (ERL) has drawn more and more attention toward its anticancer properties effect, the underlying mechanisms of ERL's anticancer properties effect remain unclear yet. So, the aim of this research was to explore the underlying anticancer mechanisms of ERL and to explore whether the reactive oxygen species (ROS)-dependent c-Jun N-terminal kinase (JNK) pathway contributed to the a...

Heat shock proteins (HSPs), which are molecular chaperones that stabilize numerous vital proteins, may be attractive targets for cancer therapy. The aim of the present study was to investigate the possible anticancer effect of single or dual targeting of HSP90 and HSP70 and the combination treatment with HSP inhibitors and chemotherapeutic agents in bladder cancer cells. The expression of HSP90...

Synergy analysis of anticancer agents is an important approach to determining the ratio and/or dose of drugs for clinical combination therapy. However, this method is rarely used to evaluate the composition of traditional Chinese medicine formulation. 'Yanhusuo San' (YHSS), which consists of yanhusuo (Rhizoma Corydalis) and Ezhu (Rhizoma Curcumae), has been an archaic Chinese medicine prescript...

BACKGROUND Inositol hexakisphosphate (IP6), a naturally occurring polyphosphorylated carbohydrate, has been reported to have significant in vivo and in vitro anticancer activity against numerous tumors. However, the molecular mechanism of the anticancer effect of IP6 has not been fully elucidated. MATERIALS AND METHODS Using K-562 human leukemia cells we analysed the induction of the erythroi...

Phospho-aspirin (PA-2) is a novel aspirin derivative that exhibits promising anticancer properties and is considerably safer than conventional aspirin. In this study, we investigated the chemotherapeutic efficacy of PA-2 in preclinical models of estrogen receptor positive (ER+) breast cancer and elucidated its mechanism of action. PA-2 inhibited the growth of ER+ cells more potently than aspiri...
