Additionally, PP1γ was significantly highly expressed in patients with age ≤ 60 years (Figure 1E), lymph node metastasis N1&N2 (Figure 1F), pathological stage III&IV (Figure 1G), and histological Grade 2&3 (Figure 1H) (P <0.05), indicating its association with age, lymph node metastasis, pathological staging, and histological grading. The gene discussed is PPP1CC; the disease is metastatic malignant neoplasm in the lymph nodes.
