A Potential Therapy Using Engineered Stem Cells Prevented Malignant Melanoma in Cellular and Xenograft Mouse Models.

Purpose: In the present study, human neural stem cells (hNSCs) with tumor-tropic behavior were used as drug delivery vehicle to selectively target melanoma. A hNSC line (HB1.F3) was transduced into two types: one expressed only the cytosine deaminase (CD) gene (HB1.

The growth of K562 human leukemia cells was inhibited by therapeutic neural stem cells in cellular and xenograft mouse models.

To confirm the anti-tumor effect of engineered neural stem cells (NSCs) expressing cytosine deaminase (CD) and interferon-β (IFN-β) with prodrug 5-fluorocytosine (FC), K562 chronic myeloid leukemia (CML) cells were co-cultured with the neural stem cell lines HB1.F3.CD and HB1.

Resveratrol induced reactive oxygen species and endoplasmic reticulum stress‑mediated apoptosis, and cell cycle arrest in the A375SM malignant melanoma cell line.

Resveratrol, a dietary product present in grapes, vegetables and berries, regulates several signaling pathways that control cell division, cell growth, apoptosis and metastasis. Malignant melanoma proliferates more readily in comparison with any other types of skin cancer. In the present study, the anti‑cancer effect of resveratrol on melanoma cell proliferation was evaluated.

Phytochemical-induced reactive oxygen species and endoplasmic reticulum stress-mediated apoptosis and differentiation in malignant melanoma cells.

Background: Phytochemicals are derived from plants, vegetables and daily products and exert chemopreventive effects. Malignant melanoma is highly metastatic, and melanoma patients can develop chemotherapeutic resistance against conventional melanoma therapies.

Methods: In the present study, we investigated the anti-cancer effect of the phytochemicals kaempferol (Kaem), genistein (Gen), and 3'3-diindolylmethane (DIM) on melanoma cell viability.

Cancer-Specific Inhibitory Effects of Genetically Engineered Stem Cells Expressing Cytosine Deaminase and Interferon-β Against Choriocarcinoma in Xenografted Metastatic Mouse Models.

Cancer treatments using stem cells expressing therapeutic genes have been identified for various types of cancers. In this study, we investigated inhibitory effects of HB1.F3.

Effects of cigarette smoke extracts on the progression and metastasis of human ovarian cancer cells via regulating epithelial-mesenchymal transition.

Cigarette smoke (CS) contains over 60 well-established carcinogens, and there are strong links between these carcinogens and smoking-induced cancers. In this study we investigated whether three types of cigarette smoke extracts (CSEs), 3R4F (standard cigarette), CSE1 and CSE2 (two commercial cigarettes), affect the proliferation, migration, and invasive activity of BG-1 human ovarian cancer cells. All three types of CSEs increased BG-1 cell proliferation at nicotine concentrations of 1.
