Summary
This study maps the fallopian tube (FT) spatial transcriptome, revealing region-specific gene expression critical for fertility and early ovarian cancer development. Key findings highlight distinct patterns in ciliation, oxidative stress, and cell adhesion markers across FT anatomy.
Area of Science:
- Reproductive Biology
- Gynecologic Oncology
- Genomics
Background:
- The fallopian tube (FT) is vital for fertility and implicated in high-grade serous ovarian cancer (HGSOC) pathogenesis.
- Understanding the spatial gene expression within distinct FT anatomical regions is crucial but underexplored.
Purpose of the Study:
- To spatially map the transcriptome of the premenopausal fallopian tube epithelium.
- To identify region-specific gene expression patterns and their functional implications.
Main Methods:
- Utilized GeoMx Digital Spatial Profiler (DSP) on premenopausal FT tissue.
- Analyzed gene expression using a targeted panel of approximately 1800 genes.
Main Results:
- Identified region-specific expression of ciliated cell markers (e.g., FOXJ1) approaching the fimbria.
- Observed elevated oxidative stress and apoptosis-related transcripts (e.g., TXNIP, BAD) in the distal FT.
- Detected a gradient in cell-cell adhesion transcripts (e.g., CDH1, CDH3) and menstrual cycle-dependent regulation of MHC-II transcripts.
Conclusions:
- Spatially regulated gene expression in the FT has significant implications for fertilization processes.
- These regional transcriptomic differences may contribute to early neoplastic changes associated with HGSOC.
- Provides a foundational spatial transcriptomic map of the human fallopian tube.
