CXCL1 and neoplasm: 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.
