Bladder cancer is a common malignant urinary tumor, and patients with bladder cancer have poor prognosis. Abnormal lipid metabolism in peroxisomes is involved in tumor progression. Hydroxysteroid dehydrogenase-like 2 (HSDL2) localized in peroxisomes regulates fatty acid synthesis. In the present study, we reported that HSDL2 was upregulated in two human bladder cancer cell lines 5637 and T24 compared to normal human urothelial cells. Furthermore, lentiviral-mediated HSDL2 knockdown inhibited the proliferation and colony formation while promoted the apoptosis of human bladder cancer T24 cells . In nude mice HSDL2 knockdown inhibited the growth of T24 derived xenografts . In conclusion, our results suggest that HSDL2 plays an oncogenic role in bladder cancer and might serve as a potential target for bladder cancer therapy.
膀胱癌是一种常见的恶性尿路肿瘤,膀胱癌患者预后不良。过氧化物酶体中异常的脂质代谢参与肿瘤的进展。定位于过氧化物酶体的羟甾类脱氢酶样 2(HSDL2)调节脂肪酸的合成。在本研究中,我们报道与正常的人尿路上皮细胞相比,在两种人膀胱癌细胞系 5637 和 T24 中 HSDL2 上调。此外,慢病毒介导的 HSDL2 敲低抑制人膀胱癌 T24 细胞的增殖和集落形成,同时促进细胞凋亡。在裸鼠中,HSDL2 敲低抑制 T24 衍生的异种移植物的生长。总之,我们的结果表明 HSDL2 在膀胱癌中发挥致癌作用,可能成为膀胱癌治疗的潜在靶点。
