Further statistical analysis revealed that the mRNA expression of AHA1, but neither Hsp90aa1 nor Hsp90ab1, is significantly correlated with the clinicopathological characteristics such as TNM stage (p = 0.035), lymph node metastasis (p = 0.012), and metastasis (p = 0.0003) (Fig. 1b, Table 1). The gene discussed is AHSA1; the disease is metastatic malignant neoplasm in the lymph nodes.
