The association between semen parameters, demographic factors, and Cumulative Live Birth Rate from Donor Insemination (cLBR -DI) was analysed using linear regression analysis. Recurrent Failure of Sperm Donation IVF (RFDI) was defined as ≤1 pregnancy despite ≥4 DICs (indicating a cLBR -DI of ≤25%). Progressive Motility Rate (PR) refers to the percentage of grade (a + b) sperm among all sperm ((a + b)/(a + b + c + d)%).

RFDI donors exhibited higher sperm concentration (96.00 [75.00, 130.00] vs. 90.00 [72.00, 122.22], p = 0.057) and lower Forward Motility Rate (95.12 [89.02, 97.01] vs. 96.59 [93.33, 97.30], p &lt; 0.001) compared to non-RFDI. Forward Motility Rate, rather than Progressive Motility Rate, correlated with cLBR -DI Compared to the normal group, HR-RFDI had an over three-fold higher risk of RFDI before (RR = 3.48, 95% CI [1.94, 6.25], p &lt; 0.0001) and after (OR = 3.04, 95% CI [1.92, 4.81], p &lt; 0.0001) PSM adjustment.

Enhancer of zeste homologue 2 (EZH2) is the catalytic subunit of polycomb repressive complex 2 (PRC2). It functions as a tumour promoter through both canonical H3K27me3 modification and noncanonical mechanisms. Although EZH2 has been developed as a potential anticancer target, the therapeutic effects of EZH2 inhibitors in solid tumours are still limited.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The levels of fatty acid and tricarboxylic acid (TCA) cycle-related metabolites were measured via high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). EZH2-knockout cells, ChIP‒qPCR, qPCR, and western blotting were used to investigate the regulatory effect of EZH2 on FADS2. The expression of FADS2 transcript variants and their correlations with prognosis in clinical OC tissues were analysed via the GEPIA 2 database. Various OC cell lines, patient-derived organoids and tumour-bearing models have been used to test the therapeutic effects of EZH2 and FADS2 inhibitors. 4D-DIA proteomics, the Seahorse assay and flow cytometry-based detection of mitochondrial function and protein synthesis were performed to explore the mechanism of combined therapy.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Findings: &lt;/strong&gt;EZH2 knockout increased FADS2 variant 1 (v1) and decreased variant 2/3 (v2/3) at both the mRNA and protein levels. EZH2 occupied the promoters of FADS2 v1 and v2/3, but the enrichment of H3K27me3 at the v2/v3 promoter was significantly lower than that at the v1 promoter. Furthermore, EZH2 inhibitors increased full-length FADS2 v1 expression and polyunsaturated fatty acid abundance in OC cells. A high FADS2 v1/v2 ratio was associated with poor prognosis in patients with OC. Targeting FADS2 with shRNAs or inhibitors reduced EZH2 levels and sensitised cancer cells to EZH2 inhibitors. The combined inhibition of EZH2 and FADS2 induced mitochondrial dysfunction and energy stress and synergised to reduce tumour growth in vitro and in vivo.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Interpretation: &lt;/strong&gt;EZH2 inhibition increases the proportion of the full FADS2 isoform through differential regulation, which suggests a poor prognosis in OC patients. Simultaneous inhibition of EZH2 and FADS2 causes mitochondrial dysfunction and energy stress in OC, resulting in a more pronounced antitumour effect.

While prostate-specific antigen (PSA) testing is widely used for screening, its diagnostic accuracy is limited, often failing to distinguish between benign and malignant prostate conditions, underscoring the need for novel biomarkers with improved diagnostic performance. This study aimed to identify and validate a panel of urinary RNA biomarkers with improved diagnostic accuracy for PCa.</p><p><strong>Methods: </strong>RNA-sequencing analysis of exfoliated cells in urine specimens identified 50 candidate RNAs. After initial qPCR testing in pooled urine, three biomarkers (TTC3, H4C5, EPCAM) with optimal specificity and sensitivity were selected as a biomarker panel. Diagnostic performance was evaluated in a case-control study divided into development (n = 243 participants) and validation (n = 646 participants) datasets. Biomarker expression was confirmed in tissue specimens, and the oncogenic function of TTC3 was assessed in vitro and in vivo.</p><p><strong>Findings: </strong>The three-biomarker urine panel robustly identified PCa with an area under the curve (AUC) of 0.96 (95% CI: 0.94-0.98) compared to 0.83 (95% CI: 0.77-0.88) for urinary prostate cancer antigen 3 (PCA3) RNA in the development dataset and 0.92 (95% CI: 0.89-0.94) compared to 0.76 (95% CI: 0.72-0.80) for PCA3 in the validation dataset. Urine biomarkers were nearly eliminated post-prostatectomy and were confirmed to originate from prostate tissue at both the RNA and protein levels. The panel maintained high diagnostic accuracy of PSA-negative PCa cases and distinguished PCa from benign prostate conditions (BPH, prostatitis). Functional studies demonstrated that TTC3 depletion significantly suppressed in vitro and in vivo tumour growth.</p><p><strong>Interpretation: </strong>This urine-based biomarker panel offers a promising sensitive and specific noninvasive diagnostic for PCa with the potential to form the basis for laboratory-developed and in vitro diagnostic assays.</p><p><strong>Funding: </strong>This study was supported by the International Prostate Cancer Foundation, JHU SKCCC (grant number P30CA006973), and Bankhead-Coley Cancer Research Program (grant number 24B16) to R.
