Abstract

Breast cancer is a complex and heterogeneous disease that poses a significant public health concern worldwide, and it remains a major challenge despite advances in treatment options. One of the main properties of cancer cells is the increased proliferative activity that has lost regulation. Dysregulation of various positive and negative modulators in the cell cycle has been identified as one of the driving factors of breast cancer. In recent years, non-coding RNAs have garnered much attention in the regulation of cell cycle progression, with microRNAs (miRNAs), circular RNAs (circRNAs), and long non-coding RNAs (lncRNAs) being of particular interest. MiRNAs are a class of highly conserved and regulatory small non-coding RNAs that play a crucial role in the modulation of various cellular and biological processes, including cell cycle regulation. CircRNAs are a novel form of non-coding RNAs that are highly stable and capable of modulating gene expression at posttranscriptional and transcriptional levels. LncRNAs have also attracted considerable attention because of their prominent roles in tumor development, including cell cycle progression. Emerging evidence suggests that miRNAs, circRNAs and lncRNAs play important roles in the regulation of cell cycle progression in breast cancer. Herein, we summarized the latest related literatures in breast cancer that emphasize the regulatory roles of miRNAs, circRNAs and lncRNAs in cell cycle progress of breast cancer. Further understanding of the precise roles and mechanisms of non-coding RNAs in breast cancer cell cycle regulation could lead to the development of new diagnostic and therapeutic strategies for breast cancer.

摘要

乳腺癌是一种复杂且异质性的疾病,在全球范围内对公共健康构成了重大威胁,尽管治疗选择有所进步,但它仍然是一个主要挑战。癌细胞的主要特性之一是增殖活性增加且失去调控。细胞周期中各种正、负调节剂的失调已被确定为乳腺癌的驱动因素之一。近年来,非编码 RNA 在细胞周期进程的调控中受到了广泛关注,其中 microRNAs(miRNAs)、环状 RNA(circRNAs)和长非编码 RNA(lncRNAs)尤为引人注目。miRNAs 是一类高度保守且具有调控作用的小非编码 RNA,在调节各种细胞和生物过程中发挥着关键作用,包括细胞周期调控。circRNAs 是一种新型的非编码 RNA,具有高度稳定性,能够在转录后和转录水平上调节基因表达。lncRNAs 也因其在肿瘤发生中的突出作用而受到广泛关注,包括细胞周期进展。新出现的证据表明,miRNAs、circRNAs 和 lncRNAs 在乳腺癌细胞周期调控中发挥着重要作用。本文总结了乳腺癌中与 miRNA、circRNA 和 lncRNA 相关的最新文献,强调了它们在乳腺癌细胞周期进展中的调控作用。进一步了解非编码 RNA 在乳腺癌细胞周期调控中的精确作用和机制,可能为乳腺癌的诊断和治疗策略的发展提供新的思路。
