[Abstract] The mammary gland undergoes extensive remodeling during pregnancy and is also subject to neoplastic processes both of which result in histological changes of the gland epithelial structure. Since the mammary tree is a complex three-dimensional structure a method is needed that provides an overview of the entire gland. Whole mounts provide this ...
Generation of Luciferase-expressing Tumor Cell Lines
[Abstract] Murine tumor models have been critical to advances in our knowledge of tumor physiology and for the development of effective tumor therapies. Essential to these studies is the ability to both track tumor development and quantify tumor burden in vivo. For this purpose, the introduction of genes that confer tumors with bioluminescent ...

[Abstract] To investigate whether endothelial Akt1 activation is sufficient to induce vascular tumor formation in the skin, we have developed a skin graft model in which a skin fragment from transgenic donor mice with inducible and endothelial cell-specific overexpression of activated Akt1 (myrAkt1) is grafted into the skin of wild type recipient mice. The ...
Establishment of Patient-Derived Xenografts in Mice
[Abstract] Patient-derived xenograft (PDX) models for cancer research have recently attracted considerable attention in both the academy and industry (Hidalgo et al., 2014; Wilding and Bodmer, 2014). PDX models have been developed from different tumor types including lung cancer to improve the drug development process. These models are used for ...

[Abstract] Obesity has been linked to breast cancer progression but the underlying mechanisms remain obscure. Being overweight or obese for a woman at the time she is diagnosed with breast cancer is linked to a high risk of recurrence regardless of treatment factors. In rodents, high body weight is also associated with increased incidence of spontaneous and ...
In vivo Bioluminescence Imaging of Luciferase-labeled Cancer Cells
[Abstract] Over the past decade, in vivo bioluminescent imaging has emerged as a non-invasive and sensitive tool for studying ongoing biological processes within living organisms (Contag et al., 1997; Contag et al., 1998). Based on the detection and quantitation of the photons produced by the oxidation of luciferin by luciferase ...
Analysis of Murine Lung Tumors by Micro PET-CT Imaging
[Abstract] Accurate live tumor imaging in mice is now possible by means of high-resolution positron emission tomography (micro-PET) and X-ray computed tomography (micro-CT). By providing a powerful tool to examine biological samples with complex structure in vivo, this technology generated a significant advance in the cancer research field, ...

[Abstract] Hanging drop assay can be used to investigate cell-cell cohesion and cell-substratum adhesion through generation of 3D spheroids under physiological conditions. It also can be used to elucidate the role of cell-cell or cell-ECM interactions in specifying spatial relationships between two (or more) different cell populations. This simple method ...
