Cancer Model

research on cancer cancer model mouse models of cancer

The laboratory mouse is widely considered as a valid and affordable model organism for studying human disease. Mouse models of cancer not only enable researchers to understand the genetic basis of tumor development in complicated and dynamic physiological systems, but also serve as irreplaceable tools for developing and testing new therapies.  Shanghai Model Organisms Center offers a variety of mouse models of cancer to meet the needs of both academic and industry partners.

Model Repository

model repository

Shanghai Model Organisms has established more than 18,000 genetically modified mouse models using three core technologies of gene editing. It has more than 10,000 proprietary genetically engineered mouse models that can be directly used for studies on gene functions, drug screening, and human diseases. At the same time, Shanghai Model Organisms has more than 30 fluorescent-labeled tumor cell lines, which can be used for in vitro experiments, studies on tumor bearing mice and other tumor researches.

Gene Knock-in

gene knock in knock in mice knock in mouse

Knock-in represents the introduction of specific mutations or exogenous genes, such as point mutations (mimicking human genetic disease) at the selected location or reporter genes (e.g., EGFP, RFP, mCherry, YFP, LacZ, Luciferase etc.) or functional cDNAs (such as Cre, Dre etc.) into a specific genomic locus through homologous recombination, thereby allowing the exogenous DNA fragment to be expressed. A simultaneous occurrence of knock-in and knock-out can be achieved by replacing a murine endogenous gene with a foreign DNA fragment.

Why We Need Humanized Mice?

P53 CKO Mouse Model

p53 knockout p53 knockout mice p53 gene

Our own-developed mouse model of p53 conditional knockout (p53-CKO) can be mated with mice carrying tissue-specific Cre expression to obtain mice with homozygous deletion of p53 in specific tissues or cells. These mice can be used for tumorigenesis and tumor mechanistic studies.

Pten CKO Mouse Model

Our own-developed mouse model of Pten conditional knockout (Pten-CKO) can be mated with mice carrying tissue-specific Cre expression to obtain mice with homozygous deletion of Pten in specific tissues or cells, thus avoiding the embryonic death caused by systemic and homozygous Pten knockout. Pten-CKO mice can be used to study tumorigenesis, anti-tumor targets, neurogenesis, glial differentiation and cerebellar development.
