The laboratory mouse has been instrumental in investigating the genetics of human disease, including cancer, for over 110 years. [1] The laboratory mouse has physiology and genetic characteristics very similar to humans providing powerful models for investigation of the genetic characteristics of disease.
40% of both human and mouse genomes can be aligned at the nucleotide level. Mice have relatively short gestation periods. Mice take a brief time to reach sexual maturity. Mice have large litter sizes. The availability of hundreds of mutations affecting almost every tissue and aspect of development. Mice may not be an ideal model for breast cancer.
The activated oncogene significantly increases the mouse's susceptibility to cancer, and thus makes the mouse a suitable model for cancer research. [2] [3] OncoMouse was not the first transgenic mouse to be developed for use in cancer research. Ralph L. Brinster and Richard Palmiter had developed such mice previously. However, OncoMouse was the ...
Patient derived xenografts (PDX) are models of cancer where the tissue or cells from a patient's tumor are implanted into an immunodeficient or humanized mouse. [1] It is a form of xenotransplantation. PDX models are used to create an environment that allows for the continued growth of cancer after its removal from a patient.
The Lewis lung carcinoma tumor model's role in cancer has been its use for research into tumor metastasis and angiogenesis properties. The model is also useful for chemotherapeutic testing in vivo. Navelbine and carboplatin, two chemotherapeutics currently on the market, were tested in C57BL mice with Lewis lung carcinoma tumors in their hind ...
Human isogenic disease models have been likened to 'patients in a test-tube', since they incorporate the latest research into human genetic diseases and do so without the difficulties and limitations involved in using non-human models. [2] Historically, cells obtained from animals, typically mice, have been used to model cancer-related pathways.
A humanized mouse is a genetically modified mouse that has functioning human genes, cells, tissues and/or organs. [1] Humanized mice are commonly used as small animal models in biological and medical research for human therapeutics.
Mouse models of colorectal cancer and intestinal cancer are experimental systems in which mice are genetically manipulated, fed a modified diet, or challenged with chemicals to develop malignancies in the gastrointestinal tract. These models enable researchers to study the onset, progression of the disease, and understand in depth the molecular ...
