Background: and purpose Prostate cancer is an comparatively prevalent clinical malignant tumor in men, impacting the lives of millions of men globally. This study measured the expression of Karyopherin Subunit Beta 1 (KPNB1) in prostate cancer cells, and made an effort to investigate how astragaloside IV affects the biological behavior, tumor growth, and mechanism of action of prostate cancer through KPNB1. Methods: Human prostate cancer and normal cells were obtained and KPNB1 expression levels in the two cells were determined using qPCR and WB. Prostate cancer cells were grouped according to the addition of astragaloside IV, KPNB1 inhibitor (importazole) alone and in combination. KPNB1, NF-κB, and cycle-related proteins were detected to be expressed at different levels in each group's cells by WB. MTT to assess the viability of the cells. To identify the cell cycle, use flow cytometry, and sphere formation experiment to observe sphere formation ability. Nude mice were purchased and subcutaneously inoculated with prostate cancer cells to establish a prostate cancer model, and grouped by tail vein injection of astragaloside IV and importazole. Tumor size was measured. KPNB1 and NF-κB expression in tumor tissues were detected by WB. The expression of proteins relevant to the cycle is observed by immunohistochemical methods. TUNEL was used to detect apoptosis of tissue cells. Results: KPNB1 expression was upregulated in prostate cancer cells (P
