Supervised hierarchical clustering of the fresh-frozen thymomas based on the histologic groups.

<p>The figure comprises of 34 tumors (GI = group I (type AB), GII = group II (types B1–B2), and GIII = group III (type B3) and one duplicate.</p

Unsupervised hierarchical clustering of the 34 fresh-frozen thymomas showing four distinct clusters (C1–C4).

<p>One sample is included as the duplicate.</p

Heat map representing the mRNA levels of <i>AKR1B10</i>, <i>JPH1</i>, and <i>COL11A1</i> genes using TaqMan qPCR system.

<p>Data is normalized to the geometric mean of the reference genes <i>IPO8 and TFRC</i>. The heat map is generated using the Applied Biosystems DataAssist™ v3.0 software. M, tumors associated with metastasis, N, tumors with no metastasis.</p

Biological processes and canonical pathways associated with metastasis and stage using Ingenuity Pathways Analysis.

<p>The top ten significant biological functions. (A) Metastasis, (B) stage, and canonical pathways. (C) Metastasis and (D) stage were grouped based on the <i>P</i> values using right tailed Fisher exact test and with threshold less than 0.05.</p

Clinical characteristics of the patients included in the gene expression analysis.
