    Abstract : High-throughput drug screening (HTS) in live cells is often a vital part of the preclinical anticancer drug discovery process. So far, two-dimensional (2D) monolayer cell cultures have been the most prevalent model in HTS endeavors. However, 2D cell cultures often fail to recapitulate the complex microenvironments of in vivo tumors. READ MORE

  2. 2. New preclinical strategies for characterization and development of anticancer drugs

    Author : Henning Karlsson; Peter Nygren; Rolf Larsson; Mattias Belting; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer; spheroids; green fluorescent protein; VLX50; VLX60; VLX600; nitazoxanide; radiation; radiosensitizer; Oncology; Onkologi;

    Abstract : Increased understanding of the molecular mechanisms underlying cancer development has shifted drug discovery towards target driven drug development the last decades, but the development of effective cancer drugs has been hampered by the lack of predictive preclinical models. 3-D cultures, considered to more accurately reflect solid tumors in vivo, have been proposed as one way to increase the predictability of clinical efficacy in cancer drug discovery and development.

  3. 3. Quiescent cancer cells : Three-dimensional cell models for evaluation of new therapeutics

    Author : Frida Ek; Mårten Fryknäs; Malin Jarvius; Rolf Larsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cancer cell quiescence; dormancy; three-dimensional; multicellular tumor spheroids; model development; cancer pharmacology; mitochondria; OXPHOS; colorectal carcinoma; hepatocellular carcinoma; Medicinsk vetenskap; Medical Science;

    Abstract : Inadequate metabolic conditions in solid tumors lead to the formation of quiescent cancer cells that are suspended in a transient cell cycle arrest. When conditions change, quiescent cancer cells can re-enter the cell cycle and cause recurrence. READ MORE

  4. 4. Construction, expression and evaluation of anti-keratin 8 single-chain antibody fragments

    Author : Rozbeh Jafari; Birgitta Sundström; Jörgen Carlsson; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single-chain antibody fragments; keratin 8; site-directed mutagenesis; heterologous expression; P. pastoris; design of experiments; multicellular tumor spheroids; immunotargeting; Biomedical Sciences; Biomedicinsk vetenskap;

    Abstract : Antibodies are glycoproteins specifically binding to a variety of antigens and today extensively used in prevention, diagnosis and treatment of diseases. Carcinomas originate from epithelial tissues and are the most common forms of human malignancies. In the necrotic areas of carcinomas significant amounts of keratins (K) are found extracellularly.

  5. 5. Development of therapeutic strategies for quiescent tumor cell populations

    Author : Xiaonan Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Phenotypic screening is an effective approach to the discovery of small-molecule drugs. In this thesis, I have used cancer cells grown as 3D microtissues (multicellular spheroids) to study the effect of anticancer drugs and as drug discovery tools. READ MORE
