Breast cancer (BC) is a major public health concern, and identifying new biomarkers and therapeutic targets is critical to improving patient outcomes. MALAT1, a long noncoding RNA, has emerged as a promising candidate due to its overexpression in BC and the associated poor prognosis. Understanding the role of MALAT1 in BC progression is paramount for the development of effective therapeutic strategies.
This review delves into the structure and function of MALAT1, and examines its expression pattern in breast cancer (BC) and its association with different BC subtypes. This review focuses on the interactions between MALAT1 and microRNAs (miRNAs) and the various signaling pathways involved in BC. Furthermore, this study investigates the influence of MALAT1 on the BC tumor microenvironment and the possible influence of MALAT1 on immune checkpoint regulation. This study also sheds light the role of MALAT1 in breast cancer resistance.
MALAT1 has been shown to play a key role in the progression of BC, highlighting its importance as a potential therapeutic target. Further studies are needed to elucidate the underlying molecular mechanisms by which MALAT1 contributes to the development of BC. In combination with standard therapy, there is a need to evaluates the potential of treatments targeting MALAT1, which may lead to improved treatment outcomes. Moreover, study of MALAT1 as a diagnostic and prognostic marker promises improved BC management. Continued efforts to decipher the functional role of MALAT1 and explore its clinical utility are critical to advancing the BC research field.
乳腺癌(BC)是一个重大的公共健康问题,寻找新的生物标志物和治疗靶点对于改善患者预后至关重要。长链非编码 RNA MALAT1 由于在 BC 中的过度表达及其与不良预后相关,已成为一个很有前途的候选物。了解 MALAT1 在 BC 进展中的作用对于开发有效的治疗策略至关重要。
本综述深入探讨了 MALAT1 的结构和功能,研究了其在乳腺癌(BC)中的表达模式及其与不同 BC 亚型的关联。本综述重点关注 MALAT1 与 microRNAs(miRNAs)的相互作用以及涉及 BC 的各种信号通路。此外,本研究调查了 MALAT1 对 BC 肿瘤微环境的影响以及 MALAT1 对免疫检查点调节的可能影响。本研究还揭示了 MALAT1 在乳腺癌耐药性中的作用。
MALAT1 已被证明在 BC 的进展中发挥关键作用,突出了其作为潜在治疗靶点的重要性。需要进一步研究阐明 MALAT1 促进 BC 发展的潜在分子机制。结合标准治疗,需要评估针对 MALAT1 的治疗方法的潜力,这可能会改善治疗结果。此外,研究 MALAT1 作为诊断和预后标志物有望改善 BC 的管理。为了推进 BC 研究领域,继续努力解析 MALAT1 的功能作用并探索其临床应用价值至关重要。
