Summary
This study reveals the HOTAIR/miR-203/CAV1 axis in breast cancer, uncovering a new mechanism for Homeobox transcript antisense RNA (HOTAIR) as a competing endogenous RNA (ceRNA). This finding offers novel therapeutic strategies for breast cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Malignant breast cancer metastasis significantly increases mortality.
- Targeted therapy is a growing trend in breast cancer treatment.
- Competing endogenous RNA (ceRNA) networks are crucial in cancer research.
Purpose of the Study:
- To investigate the unclear relationship between HOTAIR, miR-203, and Caveolin 1 (CAV1) in breast cancer.
- To elucidate the role of the HOTAIR/miR-203/CAV1 axis in breast cancer progression.
- To identify novel therapeutic targets for breast cancer.
Main Methods:
- Bioinformatic analysis.
- Experimental validation.
Main Results:
- A novel mechanistic axis, HOTAIR/miR-203/CAV1, was identified in breast cancer.
- This axis complements the known ceRNA network of HOTAIR.
- The study provides new insights into the molecular mechanisms of breast cancer.
Conclusions:
- The HOTAIR/miR-203/CAV1 axis represents a significant finding in breast cancer research.
- This axis offers a potential new avenue for breast cancer therapy.
- Further research into this axis could lead to improved treatment strategies.

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

2.4K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
