Abstract
Objective: This study aimed to elucidate the prognostic implications of deviant expressions of long non-coding RNA (lncRNA) p53 upregulated regulator of p53 levels (PURPL), microRNA-363-3p (miR-363-3p), and ADAM metallopeptidase domain 10 (ADAM10) in patients diagnosed with ovarian serous cystadenocarcinoma (OSC).
Methods: To predict and refine the targeted miRNAs and downstream target genes for PURPL, we utilized open medical databases. Through the employment of real-time RT-PCR, we conducted tissue analysis to discern the expressions of PURPL, miR-363-3p, and ADAM10 in both OSC and control tissues. The pathological correlations in the clinic and the prognostic implications of deviant expressions of PURPL, miR-363-3p, and ADAM10 in OSC patients were analyzed independently.
Results: Database inquiries revealed that PURPL might target miR-363-3p, and in turn, miR-363-3p could target ADAM10. Differential expression of PURPL, miR-363-3p, and ADAM10 was observed between OSC and paired tissues. The premature version of miR-363-3p, miR-363, correlated with overall survival (OS), while ADAM10 corresponded with progression-free survival (PFS) in ovarian cancer patients. Tissue detection displayed significantly elevated expressions of PURPL and ADAM10, and conspicuously diminished expressions of miR-363-3p in OSC tissues compared to the control tissues (P<0.05). A negative correlation was observed between the expressions of PURPL and miR-363-3p, and miR-363-3p and ADAM10, while a positive correlation was found between PURPL and ADAM10 in different ovarian tissues (P<0.05). In OSC tissues, upregulation of PURPL was associated with an advanced clinical stage, TP53 mutation, and lymph node metastasis (P<0.05), downregulation of miR-363-3p was associated with a more advanced clinical stage and lymph node metastasis (P<0.05), and overexpression of ADAM10 correlated with a more advanced FIGO stage. High expressions of PURPL and ADAM10, and low expression of miR-363-3p, were linked with poor PFS and OS in OSC patients, respectively (P<0.05). In addition, OSC patients with elevated PURPL and reduced miR-363-3p, patients with elevated PURPL and ADAM10, and patients with reduced miR-363-3p and elevated ADAM10 also demonstrated worse PFS and OS, respectively (P<0.05).
Conclusions: The anomalous expressions of PURPL, miR-363-3p, and ADAM10 might contribute to the pathogenesis of OSC via up-down stream regulation, and these abnormal expressions could serve as potential prognostic indicators for OSC patients.
