MMHCdb allows researchers to search for PDX models by such parameters as cancer site, diagnosis, genomic properties of the engrafted human tumor, and model treatment response. Fig. 3 shows the output of a search for PDX models whose engrafted tumors have amplified KRAS, the TP53 A159V mutation, a deletion of the ALB gene, and high KIT expression.
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.
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.
For instance, humanized mice have been utilized to study human-tropic pathogens, liver cancer models, and the comparison of mouse models to human diseases NSG mice engrafted with PBMCs and administered with myelin antigens in Freund's adjuvant, and antigen-pulsed autologous dendritic cells have been used to study multiple sclerosis.

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.
According to a 2015 review article, Lewis lung carcinoma is the only reproducable syngeneic lung cancer model, meaning that it is the only reproducible lung cancer model that utilizes a transplant that is immunologically compatible. Syngeneic models have proven to be useful in predicting clinical benefit of therapy in preclinical experiments.
An animal model (short for animal disease model) is a living, non-human, often genetic-engineered animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the risk of harming a human. Although biological activity in an animal model does not ensure an effect in humans ...
The method was originally employed to treat cancer patients by Dr. Manuel Hidalgo (Spanish National Cancer Research Center in Madrid). [1] The name mouse avatar or avatar mice was originally coined by the Spanish National Cancer Research Center [2] and was subsequently popularized by the journals Nature [3] and Science, [4] the Mayo Clinic [5] and The New York Times [6] among others.
