Further, the expression of SOX9, β-catenin, and c-Myc in OC tissues was upregulated and inversely correlated with miR-34c expression, indicating that rescuing miR-34c expression, thus to inhibit SOX9, β-catenin, and c-Myc expression presents a promising strategy of reducing the chemoresistance of the OC cell to DDP.
Protein tyrosine phosphatase receptor type R (PTPRR) antagonizes the Wnt signaling pathway in ovarian cancer by dephosphorylating and inactivating β-catenin.
Glutamine-fructose-6-phosphate transaminase 2 (GFPT2) promotes the EMT of serous ovarian cancer by activating the hexosamine biosynthetic pathway to increase the nuclear location of β-catenin.
Nucleus and/or cytoplasma of β-catenin expression might be associated with tumor progression and could be a possible potential predictive factor of poor prognosis in OC patients.
Taken together, this study showed that Annexin A2 inhibition suppresses proliferation and invasion in ovarian cancer via β-catenin/EMT, proposing the potential role of Annexin A2 in the prevention and treatment of ovarian cancer.
These results uncover β-catenin as a critical factor in promoting ovarian cancer aggressiveness and a new mechanism linking between β-catenin and miRNA downregulation underlying this process.
Importantly, JRK expression was aberrantly elevated in 21% of colorectal cancers, 15% of breast and ovarian cancers and was associated with increased expression of β-catenin target genes and increased cell proliferation.
Collectively, our results suggested for the first time that NGF is functionally linked to β-catenin in the migration of human ovarian cancer cells, which may be a novel therapeutic perspective to prevent the spread of ovarian carcinomas by studying the interaction between NGF/NGFRs and canonical WNT/β-catenin signaling.
Our study identifies activated Wnt signalling to be a marker for precursor lesions of OC and successfully develops a mouse model that mimics the earliest events in pathogenesis of OC by constitutively activating βcatenin.
We studied nine single nucleotide polymorphisms (SNPs) located in CTNNB1 (β-catenin) [rs4533622, rs2953], APC (rs11954856, rs351771, rs459552), and AXIN2 (rs4074947, rs7224837, rs3923087, rs2240308) in women with ovarian cancer without BRCA1/BRCA2 mutations (n = 228) and controls (n = 282).
Frequent nuclear beta-catenin accumulation and associated mutations in endometrioid-type endometrial and ovarian carcinomas with squamous differentiation.
