چکیده

Animal models constitute valuable tools for investigating the pathogenesis of cancer as well as for preclinical testing of novel therapeutics approaches. However, the pathogenic mechanisms of pituitary-tumor formation remain poorly understood, particularly in sporadic adenomas, thus, making it a challenge to model pituitary tumors in mice. Nevertheless, genetically engineered mouse models (GEMMs) of pituitary tumors have provided important insight into pituitary tumor biology. In this paper, we review various GEMMs of pituitary tumors, highlighting their contributions and limitations, and discuss opportunities for research in the field.

Genetically Engineered Mouse Embryonic Stem Cell – derived Cardiomyocytes as a Suitable Model on Drugs Toxicity In vitro

Background DOX is a powerful chemotherapeutic agent used in the treatment of solid tumors and malignant hematological diseases. However, its cardiac toxicity limits the clinical usefulness of this drug. Previous reports have shown Corticosteroids induce a cytoprotective effect on cardiomyocytes. Mouse transgenic embryonic stem cell-derived pure cardiomyocytes may be considered as a model for a...

Accelerated preclinical testing using transplanted tumors from genetically engineered mouse breast cancer models.

PURPOSE The use of genetically engineered mouse (GEM) models for preclinical testing of anticancer therapies is hampered by variable tumor latency, incomplete penetrance, and complicated breeding schemes. Here, we describe and validate a transplantation strategy that circumvents some of these difficulties. EXPERIMENTAL DESIGN Tumor fragments from tumor-bearing MMTV-PyMT or cell suspensions fr...

Modeling follicular thyroid cancer for future therapies.

Therapeutic choices are limited for undifferentiated metastatic thyroid carcinomas. Although implanted subcutaneous thyroid tumors are standard preclinical models to examine the efficacy of new therapeutic agents, these xenograft models frequently fail to predict the outcomes of clinical trials in patients with metastatic thyroid carcinomas. Genetically engineered mouse models with alterations ...

“Glowing Head” Mice: A Genetic Tool Enabling Reliable Preclinical Image-Based Evaluation of Cancers in Immunocompetent Allografts

Preclinical therapeutic assessment currently relies on the growth response of established human cell lines xenografted into immunocompromised mice, a strategy that is generally not predictive of clinical outcomes. Immunocompetent genetically engineered mouse (GEM)-derived tumor allograft models offer highly tractable preclinical alternatives and facilitate analysis of clinically promising immun...
