ABSTRACT

Renalase (RNLS) is synthesized mainly in renal tissues. The function of RNLS in cancerous renal tissues has not been investigated. We investigated the synthesis of RNLS in chromophobe renal cell carcinoma, papillary renal cell carcinoma and clear cell renal cell carcinoma with Fuhrman grades (FG): FG1, nucleoli are absent or inconspicuous and basophilic; FG2, nucleoli are conspicuous and eosinophilic and visible but not prominent; FG3, nucleoli are conspicuous and eosinophilic; FG4, extreme nuclear pleomorphism, multinucleate giant cells, and/or rhabdoid and/or sarcomatoid differentiation. We used 90 tissue samples including 15 healthy controls, 15 chromophobe renal cell carcinoma tissues and 10 papillary renal cell carcinoma renal tissues: 12 FG1, 14 FG 2, 14 FG 3 and 10 FG4. RNLS in the tissue samples was measured using enzyme linked immunosorbent assay and immunostaining of RNLS in these tissues. RNLS was significantly greater in the chromophobe renal cell carcinoma and papillary renal cell carcinoma tissues than the control. The least amount of RNLS was found in the renal tissues of clear cell renal cell carcinoma FG1; the amount of RNLS increased as the FG grades increased. Because RNLS increased significantly in renal tissues due to cancer, except for clear cell renal cell carcinoma FG1, RNLS may be useful biomarker for distinguishing grades of renal cancer. Because RNLS increases cell survival, anti-RNLS preparations may be useful for treating cancer in the future.

肾酶能否成为区分肾肿瘤的新型候选生物标志物?

摘要

肾酶 (RNLS) 主要在肾组织中合成。RNLS 在癌性肾组织中的功能尚未得到研究。我们用 Fuhrman 分级 (FG) 研究了嫌色肾细胞癌、乳头状肾细胞癌和透明细胞肾细胞癌中 RNLS 的合成:FG1,核仁不存在或不明显且嗜碱性;FG2,核仁明显,嗜酸性,可见但不突出;FG3,核仁显着,嗜酸性;FG4、极端核多形性、多核巨细胞和/或横纹肌样和/或肉瘤样分化。我们使用了 90 个组织样本,包括 15 个健康对照、15 个嫌色肾细胞癌组织和 10 个乳头状肾细胞癌肾组织:12 个 FG1、14 个 FG 2、14 个 FG 3 和 10 个 FG4。使用酶联免疫吸附试验和这些组织中 RNLS 的免疫染色来测量组织样品中的 RNLS。嫌色肾细胞癌和乳头状肾细胞癌组织中的 RNLS 显着高于对照。透明细胞肾细胞癌FG1的肾组织中RNLS含量最少;RNLS 的数量随着 FG 等级的增加而增加。由于癌症导致肾组织中 RNLS 显着增加,除了透明细胞肾细胞癌 FG1,RNLS 可能是区分肾癌分级的有用生物标志物。由于 RNLS 可提高细胞存活率,因此抗 RNLS 制剂可能在未来用于治疗癌症。嫌色肾细胞癌和乳头状肾细胞癌组织中的 RNLS 显着高于对照。透明细胞肾细胞癌FG1的肾组织中RNLS含量最少;RNLS 的数量随着 FG 等级的增加而增加。由于癌症导致肾组织中 RNLS 显着增加,除了透明细胞肾细胞癌 FG1,RNLS 可能是区分肾癌分级的有用生物标志物。由于 RNLS 可提高细胞存活率,因此抗 RNLS 制剂可能在未来用于治疗癌症。嫌色肾细胞癌和乳头状肾细胞癌组织中的 RNLS 显着高于对照。透明细胞肾细胞癌FG1的肾组织中RNLS含量最少;RNLS 的数量随着 FG 等级的增加而增加。由于癌症导致肾组织中 RNLS 显着增加,除了透明细胞肾细胞癌 FG1,RNLS 可能是区分肾癌分级的有用生物标志物。由于 RNLS 可提高细胞存活率,因此抗 RNLS 制剂可能在未来用于治疗癌症。除了透明细胞肾细胞癌 FG1,RNLS 可能是区分肾癌分级的有用生物标志物。由于 RNLS 可提高细胞存活率,因此抗 RNLS 制剂可能在未来用于治疗癌症。除了透明细胞肾细胞癌 FG1,RNLS 可能是区分肾癌分级的有用生物标志物。由于 RNLS 可提高细胞存活率,因此抗 RNLS 制剂可能在未来用于治疗癌症。
