Article Title: PFKFB3 Regulates Chemoresistance, Metastasis and Stemness via IAP Proteins and the NF-κB Signaling Pathway in Ovarian Cancer

doi: 10.3389/fonc.2022.748403

Figure Lengend Snippet: Overexpression of PFKFB3 in ovarian cancer is correlated with metastasis and poor prognosis. (A) Representative images of PFKFB3 expression in (i) normal ovarian tissue, (ii) serous, (iii) mucinous, (iv) endometrioid and (v) clear cell subtypes of tumor samples on ovarian cancer TMA (OVC1021, Biomax) by IHC staining (scale bar, 100 μm). The insets highlight regions with higher magnification. (B) Association of PFKFB3 with stage/grade/histotype in ovarian cancer. The graphs for stage and grade encompass all four histotypes. (C) Representative images of IHC staining for PFKFB3 expression in ovarian primary tumors (i, iii) and their metastatic foci (ii, iv; scale bar, 100 μm). (D) Bar chart showing PFKFB3 staining in 13 pairs of tissues. (E) Relative PFKFB3 mRNA expression in HOSE 11-12, primary cancer cells and matched ascites cancer cells from high-grade serous ovarian cancer, determined by qPCR. (F) PFKFB3 expression in HOSE 11-12 and ovarian cancer cell lines (SKOV3, OVCAR3, and TOV112D) at the mRNA level, determined by qPCR. (G) (left) Overall and (right) progression-free survival rates were analyzed with the log-rank test for PFKFB3 high/low groups of ovarian cancer patients obtained from GSE26193 (n = 107), by using the Kaplan-Meier plotter. (*p < 0.05, **p < 0.01; n.s., not significant).

Figure Lengend Snippet: A. Representative images (10× with 40× insert) of normal adjacent tissues (NAT) and adenocarcinomas. A tissue micro array (TMA) purchased from US Biomax, Inc. (PR242b) was stained for pseudouridine and imaged at 10X and 40X. Cores with Gleason 3+3, 4+3 and 5+4 were used for representative images. Staining is primarily localized to the cytoplasm of glandular cells with negligible staining of the gland cells belonging to normal adjacent tissues (NATs). B. Plot of H-scores of normal adjacent tissues and adenocarcinomas. Each individual core was evaluated by an in-house pathologist for the presence of cancer, and given an H-score. The final H-score is the summation of (1+i)pi where i is the intensity score [0 (lowest)1+, 2+, 3+, 4+(highest)] and pi is the percent of the cells with that intensity. The p-value was calculated using a two-tailed unpaired t-test in Prism, where an alpha value of 0.05 was considered significant.

Figure Lengend Snippet: NAMPT expression was analyzed with tissue microarray (TMA). Positive immunostaining for NAMPT was brown and indicated by arrow. (A) Representative immunohistochemical staining of NAMPT expression. (B) Relative intensity fold change of NAMPT expression in normal and adjacent tissue (NAT) and OSCC tissues of three grades of differentiation. **p<0.01 vs. NAT; #p<0.05 vs. well differentiated OSCC; !p<0.05 vs. moderately differentiated OSCC. Bar=100μm.

Article Snippet: The specimens of OSCC for tissue microarray (TMA) analysis were purchased from Biomax US (Rockville, MD), catalog numbers OR601a.
