Abstract:Giant panda (Ailuropoda melanoleuca) is one of the most well-known endangered species in China. Study on the molecule and gene function of giant panda genes contributes to better understanding of this species. Krüppel-like factor 4 (KLF4) is an important transcriptional factor and plays various roles in many physiological processes including cell cycle, cell growth, cell migration, cell differentiation, cell apoptosis and maintenance of normal tissue homeostasis. In addition, it is also an essential regulator during the process of somatic cell reprogramming. To further explore the role of Klf4 gene in giant panda, the full-length cDNA of giant panda Klf4 gene was cloned from mesenchymal stem cells (MSCs) using the rapid amplification cDNA ends technique, and then the structure characteristics were analyzed. Subsequently, Klf4 gene was overexpressed in the giant panda MSCs followed by exploring its regulatory role using RNA-seq. The results showed that giant panda KLF4 was conserved during evolution, and played important physiological roles in different biological processes including cell proliferation, cell apoptosis, RNA transport and protein biosynthesis. These findings lay a foundation for further studying giant pandas at molecular level and contribute to the future protection of this species.
