2. Fig 1
The TGmirV1 array dynamic range, sensitivity, and specificity. (A) MicroRNA (miRNA) was labeled and hybridized at concentrations ranging from 125 ng to 1 μg. Labeled Cel-mir-2* and Cel-Lin-4** were used as hybridization controls (red lines). The signal to concentration relationship was analyzed for 50 randomly selected miRNAs, and the average slope for all miRNAs was 0.96 ± (B) Array cross-hybridization and sequence specificity was assessed using the Let-7 family of miRNAs. Synthetic Let-7a was labeled and hybridized, and the percentage of cross-hybridization was assessed for all Let-7 family members.

Kaplan-Meier survival plots for known microRNAs (miRNAs) found to be individually associated with overall survival: (A) miR-143 (p = ); (B) miR-199a_3p (p = ); (C) miR-145 (p = ): (D) miR-100 (p = ); and (E) miR-199a_5p (p = ). Patients are split into high and low expression groups based on the median for each miRNA. (Solid lines = above median; dashed lines = below median.)

Kaplan-Meier survival plot for esophageal adenocarcinoma patients based on a microRNA (miRNA) signature. Patients were classified into high or low risk based on a median split of the risk score (log rank p = 0.005; hazard ratio 3.6).

(A) Class comparison analysis, showing the prediction of lymph node metastasis in esophageal adenocarcinoma patients for three microRNAs (miRNAs). (B) Using the three verified miRNAs (mir-99bR and mir-199a_3p and _5p) in a logistic regression model to predict lymph node metastasis, the area under the receiver operator characteristic curve was (95% confidence interval: to 0.924) and the cross-validated accuracy was 78%.
