Lewis (y) Antigen Overexpression Increases the Expression of MMP-2 and MMP-9 and Invasion of Human Ovarian Cancer Cells

Abstract: Lewis (y) antigen is a difucosylated oligosaccharide present on the plasma membrane, and its overexpression is frequently found in human cancers and has been shown to be associated with poor prognosis. Our previous studies have shown that Lewis (y) antigen plays a positive role in the process of invasion and metastasis of ovarian cancer cells. However, the mechanisms by which Lewis (y) antigen enhances the invasion and tumor metastasis are still unknown. In this study, we established a stable cell line constit… Show more

“…Cervical tumors that extended to pelvic wall or compromised the vagina, bladder or rectum, or extended beyond true pelvis (FIGO stages III-IV) were associated to a significant increase of LeY expression in our study. Overexpression of LeY antigen could be responsible for an up-regulation of matrix metalloproteinases (MMPs), which lead to breakdown the extracellular matrix (ECM), and a down-regulation of specific tissue inhibitors of metalloproteinases (TIMPs) promoting the process of invasion although the specific mechanism still need to be further studied [26].…”

“…Increased expression promotes EMT transition and metastasis in breast cancer Role in synthesising the F77 antigen which increases prostate cancer cell growth FUT1 O-fucosyltransferase important for the biosynthesis of H antigens, Lewis B, and Lewis Y Linked to prognosis in breast cancer (Milde-Langosch et al 2014). Acts as an oncogene in several cancer types (Hao et al 2008, Yan et al 2010 Role in synthesising the F77 antigen which increases prostate cancer cell growth Hexosamine biosynthetic pathway (HBP) UAP1 Final enzyme in the hexosamine biosynthetic pathway (HBP)…”

“…Although GCNT2 is not well studied in prostate cancer, increased GCNT2 has been shown to promote an epithelial-to-mesenchymal transition (EMT) and metastasis in breast cancer cells . Similarly, the fucosyltransferase FUT1 is also androgen regulated in prostate cancer cells and can act as an oncogene in several cancer types (Hao et al 2008, Yan et al 2010, MildeLangosch et al 2014. GCNT1, GCNT2 and FUT1 are believed to play a role in synthesising the prostate cancerassociated F77 antigen .…”

“…Their ability to contribute to disease pathogenesis by a variety of mechanisms is well-documented (Bafna et al, 2010;Thériault et al, 2011). Increased Le y antigens have been correlated with a number of tumorigenic effects, such as enhanced binding to mesothelial CD44, stimulation of 5 1 signaling, increased expression of MMP-2/9, and down-regulation of inhibitory TIMP-1/2 (Gao et al, 2011;Li et al, 2010b;Yan et al, 2010). A positive effect on growth factor activation has additionally been observed, as Le Y participates in EGFR signaling and aids in the secretion of the angiogenic factors VEGF and basic FGF (Basu et al, 1987;Li et al, 2010b).…”
