BDH1 and metastatic malignant neoplasm in the lymph nodes: Transcriptome sequencing results verified that the mRNA expression values of BDH1 in patients with lymph node metastases were significantly higher than those in patients without lymph node metastases with a median (IQR) of 0.490 (−0.025–1.093) versus 0.102 (−0.540–0.663) (p = 0.002) respectively (Figure 1D).
