Abstract:
Background: Triple negative breast cancers are aggressive, enriched with cancer stem cells, and lack effective targeted therapies with little side effects. Methods: We isolated cancer stem cells from two triple negative breast cancer cell lines via cell sorting following transcriptome sequencing, bioinformatics analysis, experimental and clinical validations, as well as functional investigations to explore genes capturing triple negative breast cancer features for improved diagnosis and therapeutics in clinics. Results: We found that FA2H is under-expressed in triple negative breast cancers both in vitro and in clinics, and FA2H suppresses cancer stemness via inhibiting the STAT3/IL6 axis and NFkB signaling. Conclusions: This study reports the tumor suppressive roles of FA2H on breast cancer cells through cancer stemness control. FA2H and other candidates unveiled in this study that capture the features of cancer stem cells may contribute as diagnostic marker and/or effective therapeutic targets for improved triple negative breast cancer management.
Insights
Fatty acid 2-hydroxylase (FA2H) suppresses triple-negative breast cancer stemness by inhibiting key signaling pathways. FA2H may serve as a diagnostic marker and therapeutic target for this aggressive cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Triple-negative breast cancer (TNBC) is aggressive and characterized by cancer stem cells.
- Effective targeted therapies with minimal side effects are lacking for TNBC.
Purpose of the Study:
- To identify genes associated with TNBC features for improved diagnosis and therapeutics.
- To explore the role of these genes in cancer stemness and signaling pathways.
Main Methods:
- Isolation of cancer stem cells from TNBC cell lines using cell sorting.
- Transcriptome sequencing and bioinformatics analysis.
- Experimental and clinical validation of identified genes, including functional investigations.
Main Results:
- FA2H was found to be underexpressed in TNBC samples both in vitro and in clinical settings.
- FA2H suppresses cancer stemness by inhibiting the STAT3/IL6 axis and NF-kB signaling pathways.
- FA2H demonstrates tumor-suppressive roles in breast cancer cells via cancer stemness control.
Conclusions:
- FA2H exhibits tumor-suppressive functions in breast cancer by regulating cancer stemness.
- FA2H and other identified candidate genes may serve as diagnostic markers or therapeutic targets for TNBC management.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

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...
