Anti-tumor immunity, autophagy and chemotherapy

Tumor Microenvironment-Modulating Nanoparticles Boost Chemotherapy Efficacy and Anti-tumor Immunity

Apatinib has anti-tumor effects and induces autophagy in colon cancer cells

Objective(s): Apatinib recently has been used to treat patients with gastric cancer, but the function of apatinib in colon cancer remains unclear. This study was conducted to investigate the impacts of apatinib on the biological function and its potential mechanism of colon cancer cells in vitro. Materials and Methods:The effect of apatinib in colon cancer cells were detected by assessing cell ...

RUNX3 methylation and anti-tumor immunity.

Altered DNA methylation is a hallmark of cancer genomes and has been advocated as both a marker and mechanism of the malignant phenotype. In the conventional view, such alterations include global DNA hypomethylation, linked to aberrant expression of oncogenic driver genes and more localised de novo hypermethylation at ‘CpG-island’ promoters, argued to cause inappropriate silencing of tumor supp...

Photodynamic therapy and anti-tumor immunity.

BACKGROUND AND OBJECTIVES Photodynamic therapy (PDT) efficacy appears to be enhanced in the presence of an intact immune system and PDT has been shown to augment anti-tumor immunity. The mechanisms leading to the enhancement of the host immune response to tumor are unclear. Anti-tumor immunity depends upon the presence of activated antigen presenting cells (APCs). These cells are activated by t...

Synergistic Effect of CTLA-4 Blockade and Cancer Chemotherapy in the Induction of Anti-Tumor Immunity

Several chemotherapeutics exert immunomodulatory effects. One of these is the nucleoside analogue gemcitabine, which is widely used in patients with lung cancer, ovarian cancer, breast cancer, mesothelioma and several other types of cancer, but with limited efficacy. We hypothesized that the immunopotentiating effects of this drug are partly restrained by the inhibitory T cell molecule CTLA-4 a...
