Research progress on RNA-binding proteins in breast cancer

Area of Science:

• Oncology
• Molecular Biology
• Gene Regulation

Background:

• Breast cancer is a leading cause of mortality in women, often driven by dysregulated gene expression.
• RNA-binding proteins (RBPs) are critical regulators of gene expression, influencing processes from RNA processing to translation.
• RBPs play significant roles in the development and progression of breast cancer, affecting key cellular functions.

Purpose of the Study:

• To comprehensively review and understand the multifaceted roles of RBPs in breast cancer progression.
• To highlight the importance of RBPs in key aspects of cancer development, including proliferation, migration, invasion, and stemness.
• To emphasize how understanding RBP functions can aid in early diagnosis and effective treatment strategies for breast cancer.

Main Methods:

• Literature review and synthesis of existing research on RNA-binding proteins and breast cancer.
• Analysis of the involvement of RBPs in fundamental gene expression regulatory pathways.
• Examination of RBP contributions to critical hallmarks of cancer progression in breast cancer models.

Main Results:

• RBPs are extensively involved in post-transcriptional gene regulation, impacting RNA splicing, transport, editing, localization, and translation.
• Specific RBPs have been identified as key drivers of breast cancer cell proliferation, migration, invasion, and the maintenance of cancer stemness.
• Dysregulation of RBP activity is a common feature in breast cancer, contributing to tumorigenesis and metastasis.

Conclusions:

• Comprehensive knowledge of RBP functions in breast cancer is essential for advancing the field.
• Targeting RBPs presents a promising avenue for developing novel therapeutic strategies for breast cancer.
• Further research into RBP mechanisms can lead to improved diagnostic markers and patient outcomes, enhancing survival and quality of life.
