Article Title: Correlation of ALDH1 and Notch3 Expression: Clinical implication in Ovarian Carcinomas

doi: 10.7150/jca.18955

Figure Lengend Snippet: Aldefluor assay and the expression of ALDH1 and Notch signaling genes in ovarian cancer stem cells. A. ALDH1 population in primarily-cultured human ovarian carcinoma cells was analyzed by Aldefluor assay. DEAB is a specific inhibitor of ALDH and was used to confirm gating areas. ALDH1 (+) population (6.74%) was displayed in the absence of DEAB. B. Expression of ALDH1 mRNA in parental carcinoma cells and spheroid forming cells from 5 primarily-cultured ovarian carcinoma cells (SCN 1-5). C. The mRNA expression of Notch signaling genes in FACS-sorted ALDH1 (+) ovarian cancer cells. Notch3 (1.8-fold, p = 0.046), Notch1 (1.2-fold, p = 0.007), and Hes1 (1.2-fold, p = 0.033) were significantly overexpressed in ALDH1 (+) cells compared with ALDH1 (-) cells.

Article Snippet: Briefly, blocks were cut at five micromiter thick and the sections dried at 62°C for 30 min, and then, subjected to antigen retrieval using cell conditioning solution containing Tris/borate/EDTA in a Ventana BenchMark XT Autostainer (Ventana Medical Systems, Tucson, AZ, USA) for 60 min. For double staining, the slides were incubated for 3 h with anti-ALDH1 (biorbyt, Canbrige, UK) and anti-Notch3 antibody (GeneTex, San Antonio, USA) at a concentration of 1:100.

doi: 10.7150/jca.18955

Figure Lengend Snippet: The mRNA expression of ALDH1 and Notch signaling genes in various subtypes of ovarian carcinomas and ovarian cancer cell lines. A . The mRNA expression of ALDH1 (2.6-fold, p = 0.024) and Notch3 (13.7-fold, p = 0.000) was significantly upregulated in ovarian carcinomas (OC) compared with normal epithelium (OE). Each experiment was done in triplicate (* p < 0.05). B. The mRNA expression of ALDH1 was significantly elevated in mucinous (3.8-fold, p = 0.014) and endometrioid (2.5-fold, p = 0.029) types of OC compared with OE. Serous carcinoma (2.6-fold, p = 0.24) also showed higher ALDH1 expression. Each experiment was done in triplicate (* p < 0.05). C. The mRNA expression of Notch1 (3.0-fold, p < 0.001), Notch3 (3.4-fold, p < 0.001), Jagged2 (2.6-fold, p = 0.014), Hes1 (2.7-fold, p = 0.003), and ALDH1 (2.8-fold, p < 0.001) was significantly upregulated in the chemoresistant group compared with the chemosensitive group of OSCs. D. The correlation between ALDH1 and Notch3 expression. Notch3 expression was positively correlated with ALDH1 expression (R = 0.429, p = 0.007, Spearman's correlation test). E. Dual immunohistochemical stain for ALDH1 and Notch 3 proteins in chemoresistant OSCs. The carcinoma cells showing diffuse cytoplasmic and nuclear staining with Notch 3 (red) were also stained with ALDH1 in the cytoplasm (blue-green). F. The mRNA expression of ALDH1 and Notch signaling genes in PTX-resistant SKpac cells and PTX-sensitive parent SKOV3 cells. ALDH1 and Notch 3 mRNA levels (>25-fold than parent cells) were significantly elevated in SKpac cells compared with SKOV3 cells. Each experiment was done in triplicate (* p < 0.05). G. The expression of ALDH1 and Notch signaling genes in cisplatin-resistant A2780cis cells and cisplatin-sensitive A2780 cells. ALDH1 (4.2-fold, p=0.016), Notch1 (2.5-fold,p=0.034), Notch3 (1.3-fold,p=0.312), and Jagged2 (3.6-fold,p=0.001) mRNA levels were elevated in A2780cis cells compared with A2780. Each experiment was done in triplicate. (* p < 0.05)
