Description

Advanced preclinical investigations are being incorporated into the models used to develop new cancer treatments. Although the diverse nature of the tumors is well known, cancer models are either naturally existing or purposefully generated experimental systems that exhibit characteristics similar to those of actual tumors. The lack of preclinical cancer models that effectively assess clinical testing of important innovative chemicals in human patients has hampered the development of new cancer drugs. The use of patient-derived tumors xenograft in immunocompetent mice (preclinical models) like mice, Severe Combined Immune Deficiency Mice, No Obese Diabetic (NOD)-SCID gamma mice, Recombination-Activating Gene (RAG), and NOD rag gamma mice.

These models provide insight on the etiology, molecular basis, interactions between the host and the tumor, the function of the microenvironment, and tumors heterogeneity in tumor metastasis. These models are incredibly useful in the creation of new drugs as well as in the prediction of novel cancer indicators and targeted therapy. The possibility of using cancer models as a testing ground for new drugs and treatments is addressed in this review none of the cancer models, however, are thought to be perfect because they all come with important limitations that prevent their application just yet by bridging the gap between early cancer research and translational medicine. Oncology research, like research on other diseases, is extremely dependent on a valid and adequate conceptual model. However, cancer is not a single characterized tumor however, it is a heterogeneous system with a wide range of characteristics. So selecting the model that will best depict the specific tumor system is one of the key challenges in doing a cancer examination.

Cancer models, if they are produced intentionally or naturally, exhibit similarities with tumor types. The complete understanding of tumor development, therapeutic responses, and adverse effects has been hampered by laboratory cancer models' incapacity to replicate the heterogeneity of human cancer cells, their microenvironment, and the stromal compartment. Cancer cell lines, 3D model organisms and organisms like Drosophila melanogaster, zebrafish, genetically modified mice, pigs, patientderived xenografts (PDXs), and computational cancer models are some of the experimental systems used to research human cancer. These models serve as the foundation for research into the biochemical and genetic processes and pathogenesis of cancer. The cumulative data from cancer models helps in a more thorough comprehension of the complexities of cancer development.

Genetically engineered mouse models the genetically engineered mouse models (GEMMs) were developed since the intrinsic features and physiology of xenografts do not delineate the genetic characteristics of a human tumor. Researcher may now change the mouse genome in a conditional or constitutive approach to affect the expression of important genes that are involved in the formation of specific cancers. This is possible due to technological improvement over the past several generations. In order to achieve loss or gain of oncogene or tumor suppressor gene activity, which is reflected in the phenotype of the tumor, GEMMs have assisted in ontogenesis by removing the molecular pathways. This has helped therapy to validate critical genes as targets. By revealing the mechanism of action of proteins associated with cancer, Drosophila melanogaster has made a significant contribution to illuminating the molecular basis of cancer biology tumorous tissue resides in the Outer Proliferative Centre (OPC) and Central Brain (CB) regions in the adult brain.
