Upregulation of miR-106b is associated with advanced clinical stage and positive lymph node metastasis in CRC patients. a High expression of miR-106b was associated with lymph node metastasis; patients were classified into lymph node metastasis negative group (LN-negative) and positive group (LN-positive). bThe expression levels of miR-106b in different clinical stage of CRC patients. The expression of miR-106b was quantified by qRT-PCR and normalized to U6 RNA. *P < 0.05, **P < 0.01, NS: non- significant
