    Insights into mechanisms of tumor dissemination from circulating tumor cell lines of small cell lung cancer

    Gerhard Hamilton , Barbara Rath
    Despite the fact that the majority of cancer patients succumb to metastatic disease, most aspects of tumor metastasis are not understood in detail at present. Cell biologic steps of dissemination are difficult to characterize in human tumors and research is in large part confined to cell line and experimental animal studies. Epithelial-mesenchymal transition (EMT), intravasation of malignant cells, dissemination as circulating tumor cells (CTCs) and eventually mesenchymal-epithelial transition (MET) at distal sites are steps believed to be involved in metastasis. Small cell lung cancer... Read more

    Targeting Toll-like receptors against cancer

    Bing Du , Qiu-Li Jiang , Joseph Cleveland , Bing-Rong Liu , Dekai Zhang
    The discovery of Toll-like receptors (TLRs) about 20 years ago was a remarkable achievement not only in the field of immunology but also in the field of medicine. The TLRs are a family of pattern recognition receptors which play an important role in immune responses by recognizing pathogen-associated molecular patterns. The TLRs also recognize danger-associated molecular patterns, which are associated with some diseases such as cancer. Recent evidence shows that TLRs are expressed not only in immune cells but also in tumor cells. The TLRs appear to play a role in tumor progression and... Read more

    Nanocarrier drugs in the treatment of brain tumors

    Tereza Cerna , Marie Stiborova , Vojtech Adam , Rene Kizek , Tomas Eckschlager
    Nanoparticle-mediated targeted delivery of drugs might significantly reduce the dosage and optimize their release properties, increase specificity and bioavailability, improve shelf life, and reduce toxicity. Some nanodrugs are able to overcome the blood-brain barrier that is an obstacle to treatment of brain tumors. Vessels in tumors have abnormal architecture and are highly permeable; moreover, tumors also have poor lymphatic drainage, allowing for accumulation of macromolecules greater than approximately 40 kDa within the tumor microenvironment. Nanoparticles exploit this feature, known... Read more

    DNA damage-induced nuclear factor-kappa B activation and its roles in cancer progression

    Wei Wang , Arul M. Mani , Zhao-Hui Wu
    DNA damage is a vital challenge to cell homeostasis. Cellular responses to DNA damage (DDR) play essential roles in maintaining genomic stability and survival, whose failure could lead to detrimental consequences such as cancer development and aging. Nuclear factor-kappa B (NF-kB) is a family of transcription factors that plays critical roles in cellular stress response. Along with p53, NF-kB modulates transactivation of a large number of genes which participate in various cellular processes involved in DDR. Here the authors summarize the recent progress in understanding DNA damage response... Read more

    Role of adenosine in tumor progression: focus on A2B receptor as potential therapeutic target

    Claudia Sorrentino , Silvana Morello
    Adenosine receptors are a family of G-coupled receptors which mediate the anti-inflammatory and immune-suppressive effects of adenosine in a damaged tissue. A large number of evidence indicate that the accumulation of adenosine under hypoxic conditions favors tumor progression, helping cancer cells to evade immune responses. Tumor cells and/or lymphoid and myeloid cells can express the adenosine-generating enzyme CD73 and/or A2A receptor, which in turn strongly suppresses an effective T-cell-mediated response, while promotes the activity of suppressive cells such as Treg and myeloid-derived...
