(A) Decreased expression of TCEAL4 in ATCs as compared to normal thyroid tissues and PTCs as shown by SQ-PCR. The lane designations are as follows: M, size markers; 1–5, normal thyroid samples, 6–10, primary papillary thyroid cancer samples, 11–15, primary anaplastic thyroid cancer samples. (B) Results of quantitative RT-PCR. The average expression level of TCEAL4 among five normal thyroid tissues was set at 1.00, then relative expression ratios were calculated between normal and cancerous tissues.
