Starting with the hypothesis formulated by Judah Folkman that tumor growth is angiogenesis-dependent, this area of research has a solid scientific foundation, and inhibition of angiogenesis is a major area of therapeutic development for the treatment of cancer. This chapter offers an account of the most relevant discoveries in this field of biomedical research.

The Role of the Dysregulation of circRNAs Expression in Glioblastoma Multiforme.

Primary brain tumors that were the most severe and aggressive were called glioblastoma multiforme (GBM). Cancers are caused in part by aberrant expression of circular RNA. Often referred to as competitive endogenous RNA (ceRNA), circRNA molecules act as "miRNA sponges" in cells by decreasing the inhibitory impact of miRNA on their target genes and hence raising the expression levels of those genes.

Gastrointestinal stromal tumors (GIST), driven by KIT and PDGFRA mutations, are the most common mesenchymal tumors of the gastrointestinal tract. Although tyrosine kinase inhibitors (TKIs) have advanced treatment, resistance mutations and off-target toxicity limit their efficacy. This study develops covalent TKIs targeting drug-resistant GIST through structure-based design, synthesis, and biological evaluation.

Aim: The primary objective of this study is to investigate the impact of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) and its functional receptor, fibroblast growth factor-inducible 14 (Fn14), on the process of vascular smooth muscle cell (VSMC) senescence.
Methods: Rat arterial VSMCs were cultured with angiotensin II to establish a model of premature senescence. The effects of TWEAK and Fn14 on senescent VSMCs were evaluated.
Single Cell-Pair Proteomics for Decoding Immune-Cancer Cell Interactions.

The efficacy of cancer immunotherapy is significantly influenced by the heterogeneity of individual tumors and immune responses. To investigate this phenomenon, a microfluidic platform is constructed for profiling immune-cancer cell interactions at the single-cell proteomics level for the first time. Based on the platform, a comprehensive workflow is proposed for achieving accurate single-cell pairing of an immune cell and a cancer cell with low cell damage and high success rate up to 95%, cell pair co-culture, and real-time microscopic monitoring of the cell-pair interactions, cell pair retrieval, mass spectrometry-based proteomic analysis of singe cell pairs, and decoupling of the proteomic information for each cell within the cell pair with the stable-isotope labeling method.

Introduction: Biliary tract cancer (BTC) comprises a clinically diverse and genetically heterogeneous group of tumors along the intra- and extrahepatic biliary system (intrahepatic and extrahepatic cholangiocarcinoma) and gallbladder cancer with the common feature of a poor prognosis, despite increasing molecular knowledge of associated genetic aberrations and possible targeted therapies. Therefore, the search for even more precise and individualized therapies is ongoing and preclinical tumor models are central to the development of such new approaches.
Areas Covered: The models described in the current review include simple and advanced in vitro and in vivo models, including cell lines, 2D monolayer, spheroid and organoid cultures, 3D bioprinting, patient-derived xenografts, and more recently, machine-perfusion platform-based models of resected liver specimens.
