Abstract:
There is definitely a need for the development of new drugs for the treatment and cure of endometrial cancer. In addition there are various new drugs or phyto-remedies under development which are intended for use in the treatment and prevention of breast cancer, for the treatment of menopausal symptoms and for hormone replacement therapy. The efficacy of novel drugs targeting steroid receptors in endometrial cancers has to be evaluated and the safety of other endocrine measures on endometrial cancers or on endometrial carcinogenesis has to be assessed. For these experimental purposes five main classes of experimental models are available: spontaneous endometrial tumorigenesis models in inbred animals (Donryu rats, DA/Han rats, BDII/Han rats), inoculation tumors from chunks of tumors (rat EnDA-tumor, human EnCa 101 tumor) or from inoculated tumor cell lines (rat RUCA-I cells, human Ishikawa and ECC-1 cells), developmental estrogenic exposure or chemical carcinogen exposure of CD-1 and ICR mice, transgenic approaches such as mice heterozygous regarding the tumor suppressor gene PTEN (pten(+/-)-mice) and endometrial tumor cell lines cultured under conditions promoting in vivo-like morphology and functions e.g. cell culture on reconstituted basement membrane. Although the number of models is comparatively small, most aspects related to functions of estrogenic or gestagenic substances are assessable, particularly if various experimental models are combined. Whereas models based on human endometrial adenocarcinoma cells are widely used, the properties and advantages of animal-derived models have mainly been ignored so far.
Insights
Developing new drugs for endometrial cancer is crucial. Researchers can evaluate novel therapies and endocrine treatments using various experimental models, including animal and cell-based systems.
Area of Science:
- Oncology
- Endocrinology
- Pharmacology
Background:
- Endometrial cancer necessitates novel therapeutic strategies.
- Existing research focuses on phyto-remedies for breast cancer, menopausal symptoms, and hormone replacement therapy.
- Evaluating novel drugs targeting steroid receptors and assessing endocrine measures in endometrial cancer is critical.
Purpose of the Study:
- To review and assess available experimental models for studying endometrial cancer.
- To determine the utility of these models for evaluating novel drugs and endocrine therapies.
- To highlight the potential of underutilized animal models.
Main Methods:
- Review of five main classes of experimental models: spontaneous tumorigenesis in rats, inoculation tumors (tissue chunks and cell lines), developmental/chemical carcinogen exposure in mice, transgenic PTEN (+/-) mice, and in vitro cell cultures on basement membranes.
- Assessment of models for evaluating estrogenic and gestagenic substances.
- Comparison of human and animal-derived models.
Main Results:
- A range of experimental models are available for studying endometrial cancer, including spontaneous, inoculation, exposure, transgenic, and cell culture models.
- Most aspects of estrogenic and gestagenic substance functions can be assessed, especially when models are combined.
- Human endometrial adenocarcinoma cell-based models are widely used, while animal-derived models are often overlooked.
Conclusions:
- A combination of diverse experimental models can effectively assess novel drugs and endocrine therapies for endometrial cancer.
- Animal models offer valuable, yet underexplored, advantages for endometrial cancer research.
- Further investigation and utilization of animal models are recommended for comprehensive drug development and safety assessment.
