Zebrafish is a widely used, robust vertebrate model that is accessible for genetic modification, well suited for imaging, easy to manipulate, has a short generation time and low cost. Zebrafish has been increasingly used for disease modeling and cancer studies, and it has come forward as an attractive model for drug discovery and personalized medicine studies in recent years. Our group aims to develop novel zebrafish models and technology that will contribute to the zebrafish reseach mainly in the field of disease research and personalized medicine.
Zebrafish tumors are strikingly similar to human tumors both genetically and pathologically. We generate zebrafish “humanized tumors” by overexpression of human oncogenes in selected tissues such as melanocytes and liver. Various genetic tools allow us to create time and space controlled expression of such oncogenes, in significantly shorter time and reduced cost than rodent models. Xenotrasnplantation of human cancer cells to zebrafish host is another technology we use to facilitate cancer studies. We apply and improve this technology to study cancer metastasis, angiogenesis and drug response. In long term we aim to develop robust patient derived xenografts (PDX) methodology and use it as a tool for personalized medicine in collaboration with local oncologists.
RARE DISEASE MODELS:
Zebrafish offers several advantages for rare disease modeling, and drug discovery. We are using CRISPR/Cas9 technology to generate mutations in disease genes. We collaborate with clinicians to generate genetic models of rare diseases in zebrafish. We are particularly interested in diseases that are more common in Turkey due to consanguinity.
