Objective: Cytoreductive surgery followed by adjuvant chemotherapy is a standard frontlinetreatment for epithelial ovarian cancer (EOC). We aimed to develop an ovarian cancer riskscore (OVRS) based on the expression of 10 ovarian-cancer-related genes to predict thechemoresistance, and outcomes of EOC patients. Methods: We designed a case-control study with total 149 EOC women including 75chemosensitives and 74 chemoresistants. Gene expression was measured using thequantitative real-time polymerase chain reaction. We tested for correlation between theOVRS and chemosensitivity or chemoresistance, disease-free survival (DFS), and overallsurvival (OS), and validated the OVRS by analyzing patients from the TCGA database. Results: The chemosensitive group had lower OVRS than the chemoresistant group (5 vs. 15, p≤0.001, Mann-Whitney U test). Patients with disease relapse (13 vs. 5, p<0.001, Mann Whitney U test) or disease-related death (13.5 vs. 6, p<0.001) had higher OVRS than thosewithout. OVRS ≥10 (hazard ratio=3.29; 95% confidence interval=1.94–5.58; p<0.001) was theonly predictor for chemoresistance in multivariate analysis. The median DFS (5 months vs. 24 months) and OS (39 months vs. >60 months) of patients with OVRS ≥10 were significantlyshorter than those of patients with OVRS <9). The high OVRS group also had significantlyshorter median OS than the low OVRS group in 255 patients in the TCGA database (39 vs. 49months, p=0.046). Conclusions: Specific genes panel can be clinically applied in predicting the chemoresistanceand outcome, and decision-making of epithelial ovarian cancer.

Purpose: Fusarium species are among prevalent airborne fungi and causative agents of human respiratory atopic disorders. We previously identified a 36.5-kDa F. proliferatum component recognized by IgE antibodies in 9 (53%) of the 17 F. proliferatum-sensitized atopic serum samples. The purpose of this study is to characterize the 36.5-kDa allergen of F. proliferatum. Methods: Characterization of allergens and determination of IgE cross-reactivity were performed by cDNA cloning/expression and immunoblot inhibition studies. Results: Based on the finding that the 36.5-kDa IgE-binding component reacted with the mouse monoclonal antibody FUM20 against fungal vacuolar serine protease allergens, the cDNA of F. proliferatum vacuolar serine protease (Fus p 9.0101) was subsequently cloned. Nine serum samples from respiratory atopic patients with IgE binding to the vacuolar serine protease allergen of Penicillium chrysogenum (Pen ch 18) also showed IgE-immunoblot reactivity to rFus p 9.0101. The purified rFus p 9.0101 can inhibit IgE and FUM20 binding to the 36.5-kDa component of F. proliferatum. Thus, a novel and important Fus p 9.0101 was identified. The rPen ch 18 can inhibit IgE binding to Fus p 9.0101. It indicates that IgE cross-reactivity between Fus p 9.0101 and Pen ch 18 also exists. Furthermore, neither rFus p 9.0101 K88A nor rPen ch 18 K89A mutants inhibited IgE binding to rFus p 9.0101. Lys88 was considered a critical core amino acid in IgE binding to r Fus p 9.0101 and a residue responsible for IgE cross-reactivity between Fus p 9.0101 and Pen ch 18 allergens. Conclusions: Results obtained from this study indicate that vacuolar serine protease may be a major allergen of F. proliferatum and an important IgE cross-reactive pan-fungal allergen, and provide important bases for clinical diagnosis of fungal allergy.
