Abstract

Major fraction of the human genome is transcribed in to the RNA but is not translated in to any specific functional protein. These transcribed but not translated RNA molecules are called as non-coding RNA (ncRNA). There are thousands of different non-coding RNAs present inside the cells, each regulating different cellular pathway/pathways. Over the last few decades non-coding RNAs have been found to be involved in various diseases including cancer. Non-coding RNAs are reported to function both as tumor enhancer and/or tumor suppressor in almost each type of cancer. Urothelial carcinoma of the urinary bladder is the second most common urogenital malignancy in the world. Over the last few decades, non-coding RNAs were demonstrated to be linked with bladder cancer progression by modulating different signalling pathways and cellular processes such as autophagy, metastasis, drug resistance and tumor proliferation. Due to the heterogeneity of bladder cancer cells more in-depth molecular characterization is needed to identify new diagnostic and treatment options. This review emphasizes the current findings on non-coding RNAs and their relationship with various oncological processes such as autophagy, and their applicability to the pathophysiology of bladder cancer. This may offer an understanding of evolving non-coding RNA-targeted diagnostic tools and new therapeutic approaches for bladder cancer management in the future.

摘要

人类基因组的大部分转录为RNA,但未翻译为任何特定的功能蛋白。这些转录但未翻译的RNA分子被称为非编码RNA(ncRNA)。细胞内存在数千种不同的非编码RNA,每种都调节不同的细胞途径。在过去几十年中,已发现非编码RNA参与包括癌症在内的各种疾病。据报道,非编码RNA在几乎每种癌症中都兼具肿瘤增强子和/或肿瘤抑制因子的功能。膀胱尿路上皮癌是世界上第二常见的泌尿生殖系统恶性肿瘤。在过去几十年中,研究表明非编码RNA通过调节不同的信号通路和细胞过程,如自噬、转移、耐药性和肿瘤增殖,与膀胱癌进展相关。由于膀胱癌细胞的异质性,需要更深入的分子特征分析来确定新的诊断和治疗方案。本综述强调了关于非编码RNA的当前研究结果及其与自噬等各种肿瘤学过程的关系,以及它们在膀胱癌病理生理学中的适用性。这可能有助于理解未来不断发展的以非编码RNA为靶点的诊断工具和膀胱癌管理的新治疗方法。
