Abstract:
Triple-negative breast cancers are highly aggressive, a heterogeneous form of breast cancer with a high re-occurrence rate that further lacks an efficient treatment strategy and prognostic marker. The tumor microenvironment of the disease comprises cancer-associated fibroblasts, cancer stem cells, immunological molecules, epithelial-mesenchymal transition, and a metastatic microenvironment that contributes to disease progression and metastasis to distant sites. Emerging evidence indicated that miRNA clusters would be of clinical utility as they exert an oncogenic or tumor suppressor role in TNBC. The present review article aims to highlight the therapeutic significance of miRNA in targeting the above-mentioned signaling cascades and modulating the intracellular crosstalk in the tumor microenvironment of TNBC. Prognostic implications of miRNAs to depict disease-free survival, distant metastasis-free survival, relapse-free survival, and overall survival outcome were also unveiled.
Insights
Triple-negative breast cancer (TNBC) is aggressive and lacks effective treatments. MicroRNAs (miRNAs) show therapeutic potential by targeting TNBC
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Triple-negative breast cancer (TNBC) is an aggressive, heterogeneous cancer subtype with high recurrence rates and limited therapeutic options.
- The tumor microenvironment in TNBC, including cancer-associated fibroblasts and epithelial-mesenchymal transition, promotes disease progression and metastasis.
- MicroRNAs (miRNAs) are emerging as key regulators with oncogenic or tumor-suppressive roles in TNBC development.
Conclusions:
- miRNAs represent a promising avenue for novel therapeutic strategies against triple-negative breast cancer.
- Targeting miRNAs can modulate the complex tumor microenvironment, potentially inhibiting TNBC progression and metastasis.
- Further research into miRNA-based diagnostics and therapeutics is warranted for improved TNBC patient management.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
