  • For decades we have been learning about the interplay between tumors and the immune system. Our knowledge seemed somewhat incomplete and indirect, like listening to the ocean waves through a shell. Only recently, cancer immunotherapy has started to become a reality, with Provenge (Dendreon Corporation, WA), an autologous antigen-presenting cell preparation, earning the approval of United States Food and Drug Administration (FDA) for the treatment of advanced prostate cancer in 2010.

  • Angiogenesis is an extension process of the cardiovascular network within human body. It is usually triggered by the demand of oxygen and nutrients from the fast growing tissue and uncontrollably dividing cells, as seen during wound healing and tumor progression. This book focuses on tumor angiogenesis and includes 8 chapters written by highly experienced scholars from five different countries.

  • Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and heterogeneous neoplasms with overall increasing incidence, but not an associated increase in survival rate over the past few decades. Tumors originate from at least 16 different cells of diffuse endocrine system (DES), scattered through mucosa of gastrointestinal tract. They are mainly sporadic, but sometimes exhibit familial inheritance.

  • a-enolase (ENOA) is a metabolic enzyme involved in the synthesis of pyru-vate. It also acts as a plasminogen receptor and thus mediates activation of plasmin and extracellular matrix degradation. In tumor cells, EMOAis upregulated and supports anaerobic proliferation (Warburg effect), it is expressed at the cell surface, where it promotes cancer invasion

  • DNA tumor viruses ensure genome amplification by hijacking the cellular replication machinery and forcing infected cells to enter the S phase. The retinoblastoma (Rb) protein controls the G1⁄S checkpoint, and is targeted by several viral oncoproteins, among these the E7 protein from human papillomaviruses (HPVs).

  • In early studies on energy metabolism of tumor cells, it was proposed that the enhanced glycolysis was induced by a decreased oxidative phosphoryla-tion. Since then it has been indiscriminately applied to all types of tumor cells that the ATP supply is mainly or only provided by glycolysis, without an appropriate experimental evaluation.

  • Plasminogen activator inhibitor type 1 (PAI-1) is induced by many proin-flammatory and pro-oxidant factors. Among them, tumor necrosis factora (TNFa), a pivotal early mediator that regulates and amplifies the develop-ment of inflammation, is one of the strongest PAI-1 synthesis activators. Location of the TNFa response element in the PAI-1 promoter is still ambiguous.

  • trans-[PtCl2NH3(4-Hydroxymethylpyridine)] (trans-PtHMP) is an analogue of clinically ineffective transplatin, which is cytotoxic in the human leuke-mia cancer cell line. As DNA is a major pharmacological target of anti-tumor platinum compounds, modifications of DNA by trans-PtHMP and recognition of these modifications by active tumor suppressor protein p53 were studied in cell-free media using the methods of molecular biology and biophysics.

  • The tumor suppressor p16 INK4a has functions beyond cell-cycle control via cyclin-dependent kinases. A coordinated remodeling ofN- and O-glycosyla-tion, and an increase in the presentation of the endogenous lectin galectin-1 sensing these changes on the surface of p16 INK4a -expressing pancreatic carcinoma cells (Capan-1), lead to potent pro-anoikis signals.
