Objectives: Potassium channels have been proposed to promote cancer cell proliferation and metastases. Thus, we investigated the expression pattern of three 2-pore domain potassium channels (K2Ps) TASK1, TASK3 and TRESK in advanced oral squamous cell carcinoma (OSCC), the commonest oral malignancy.

Design: We used 4-nitroquinoline-1-oxide (4-NQO) to induce high grade OSCC in male adult rats.

Purpose: Retinoblastoma (RB) is the most common primary intraocular tumor in children. Chemotherapy is currently the main method of RB treatment. Unfortunately, RB often becomes chemoresistant and turns lethal.

Purpose: The goal of this study was to provide an experimental basis for the clinical application of cell immunotherapy on RB in combination with chemotherapy treatment and to explore the mechanism of their combined cytotoxicity.

Methods: We investigated the antitumor effect of cytokine-induced killer cells (CIK), co-cultivated with dendritic cells pulsed with tumor antigens (DC-Ag) and/or with carboplatin. Cytotoxicity was evaluated on a retinoblastoma cell line (RB-Y79) by FCM and immunofluorescence microscopy.

Retinoblastoma (RB) is a challenging disease that affects mostly young children. Chemical therapy has been shown to have limitations during clinical practice, principally because of the ability of RB to become resistant to the treatment. Nevertheless, chemotherapy is still the main treatment for RB, and immunotherapy has become a promising treatment for most solid tumors with fewer side effects than traditional therapies.
