Transcriptomic profiling and RT-PCR revealed upregulation of matrix metallopeptidase 1 (MMP1), pregnancy-associated plasma protein A (PAPPA), and C-X-C motif chemokine ligand 1 in cyst-derived stromal cells compared to those from the normal ovary and fallopian tube, implicating these genes in extracellular matrix remodeling and tumor–stroma crosstalk. This evidence concerns the gene XCL1 and neoplasm.
