Abstract:
The study and comprehension of the molecular mechanisms underlying cancer biology strongly rely on mouse modeling. An ideal mouse model should have molecular, histopathological, and etiological characteristics as close as possible to those of the corresponding human tumors. Among solid tumors, colorectal cancer (CRC) is one of the malignancies that best suits reproduction in an animal model: it evolves through a progressive set of molecular events and is generally associated with a precise histopathology and a neat cataloging of stages and grades. The development of refined CRC mouse models over several decades has seen them recently evolve toward sophisticated systems that ever more closely approximate the human pathology, with different models addressing different human CRC subtypes. In particular, a metastatic CRC model has been seen as a "holy grail" in this field, and we describe in this review the path taken to achieve metastatic models and discuss the path forward.

Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
