However, the current research on ABCG2 expression and its relationship with renal cancer stem cells is still very limited. In this study, renal cancer tissue specimens will be collected, and the expression of ABCG2 will be detected by immunohistochemistry and Western blot techniques. Renal cancer stem cells will be separated by flow cytometry. By comparing the expression of ABCG2 in renal cancer patients with different clinical staging, tissue types, and prognosis, the expression characteristics of ABCG2 in renal cancer will be explored. Through the ation of primary tumor spheres and cell proliferation experiments, it is proved that ABCG2 is involved in the regulation of renal cancer stem cell characteristics. This study is expected to provide new ideas for further research on the molecular mechanisms of renal cancer development, and provide guidance for exploring the characteristics of renal cancer stem cells and related treatments. 【Keywords】 ABC transporter glutathione S-transferase 2; renal cancer; multidrug resistance; stem cells
