Hyperforin is a prenylated phloroglucinol present in the medicinal plant St John's wort (Hypericum perforatum). The compound has many biological properties, including antidepressant, anti-inflammatory, antibacterial and antitumor activities. This review focuses on the in vitro antileukemic effects of purified hyperforin and related mechanisms in chronic lymphoid leukemia (CLL) and acute myeloid leukemia (AML) - condition Read More

Pulmonary delivery of drug-loaded nanoparticles is a novel approach for lung cancer treatment and the conjugation of nanoparticles to a targeting ligand further promotes specificity of the carrier cargo to cancer cells. Notably, the epithelial cell adhesion molecule (EpCAM, CD326) is over expressed in lung cancer. Here, we report the safety and proof-of-concept efficacy of drug-loaded nanoparticles and EpCAM immunona Read More

Allogeneic stem cell transplantation is commonly used in the treatment of high-risk acute myeloid leukemia (AML). This intensive treatment has a high early transplant-related mortality, and an additional significant cause of death in these patients is later AML relapse. Retransplantation can be considered for a minority of patients, but only 10-20% of selected patients then achieve long-term survival. Donor lymphocyte infusion ( Read More

Background: In patients with Osteosarcoma (OS), larger primary tumor size correlates with higher metastasis incidence and lower overall survival. Identifying the mechanisms that control primary tumor growth can lead to the new therapeutic approaches and improve prognosis. Cytoskeleton regulatory molecules play an important role in tumor cells proliferation and motility. In the current study, we investigated the role of sca Read More

Effective treatments to prevent recurrence or progression of non-muscle-invasive bladder cancer, or to inhibit metastasis of muscle-invasive forms of the disease, would deliver significant patient benefit. Here the involvement of STAT signalling and the chemopreventive potential of diindolylmethane (DIM) in human bladder cancer were investigated. Muscle-invasive bladder cancer tissues were characterised by nucle Read More

Treatment outcomes for chronic myelogenous leukemia (CML) have shown major improvements as a result of the development of the tyrosine kinase inhibitors (TKIs) imatinib, nilotinib and dasatinib for the disease-specific molecular target BCR-ABL1 tyrosine kinase (TK), but a cure of CML by BCR-ABL1 TKIs has been rarely achieved. CML cells are protected from cytotoxic insults, including those by TKIs, through various coll Read More

Targets for cancer therapy are conventionally selected by identification of molecules acting downstream of established tumour suppressors and oncoproteins, such as p53, c-Myc and Ras. However, the forward genetics approach provides an alternative, conceptually distinct, strategy for identifying target molecules de novo. This approach, which uses unbiased selection protocols relying directly on the effects of the genes Read More

The use of adult stem cells as gene delivery vehicles is a novel and attractive strategy for cancer therapy. Mesenchymal stem cells (MSCs) provide a promising source for stem cell-based gene therapies. Interleukin-24 (IL24) has been suggested as an effective anticancer agent. However, a lack of tumor-targeted delivery and a host immune response to viral vehicles has hindered its application for cancer therapy. In this study, w Read More

TRPC channels are Ca2+-permeable cationic channels controlling Ca2+ influx response to the activation of G protein-coupled receptors and protein tyrosine kinase pathways or the depletion of Ca2+ stores. Here we aimed to investigate whether TRPC can act as the potential therapeutic targets for ovarian cancer. The mRNAs of TRPC1, TRPC3, TRPC4 and TRPC6 were detected in human ovarian adenocarcinoma. The spliced vari Read More
