RESUMEN

Adriamycin is an effective anticancer drug used in a wide range of cancers. Anticancer drugs modulate oncogenes and nodal regulatory molecules that affect cell differentiation and organismal development. In this study, we explore the effect of adriamycin on Kruppel-like factor4 (Klf4), an essential pluripotent factor by choosing zebrafish embryos as a model system. Klf4 is involved in the regulation of cellular growth, proliferation, and differentiation. In zebrafish embryogenesis, Klf4 is a major regulator of differentiation of polster in the anterior mesendoderm region of cells into hatching gland cells. The importance of this study is to check the effect of adriamycin on embryonic development. We found, adriamycin dose dependently altered the gene expression level of Klf4 that occurs in parallel to its detrimental effect on hatching. Supportively, cathepsin L and cyclase-associated protein1 are the other two markers of hatching that are altered along with Klf4.
