中文摘要: 目的 分析细胞因子信号抑制物 4(SOCS4)在食管鳞状细胞癌增殖和迁移中的作用,并探讨与其相互作用的 Cullin-RING泛素连接酶(CRL5)和 Shc1结合蛋白(SHCBP1)之间的关系。方法 通过 CCK8实验、克隆形成实验、划痕实验和 transwell实验检测 SOCS4对食管鳞状细胞癌Eca-109细胞增殖和迁移的影响。应用免疫共沉淀联合质谱分析检测与 SOCS4相互作用的蛋白。结果 SOCS4在食管鳞状细胞癌中高表达(P<0.010),且与预后负相关(P=0.048)。 SOCS4高表达促进食管鳞状细胞癌 Eca-109细胞增殖和迁移( t=2.503,P=0.046)。 SOCS4与 CRL5和 SHCBP1相互作用,并促进 SHCBP1泛素化(P<0.001)。敲低 SHCBP1抑制了食管鳞状细胞癌 Eca-109细胞增殖和迁移(Day2:F=7.903,P=0.005;Day3:F=11.569,P<0.001;Day4:F=3.894,P=0.043)。敲低 SHCBP1逆转了 SOCS4对食管鳞状细胞癌 Eca-109细胞增殖和迁移的促进作用(Day3:F=7.343,P=0.030)。结论 SOCS4高表达患者预后较差, SOCS4通过泛素化 SHCBP1促进食管鳞状细胞癌增殖与迁移。
Abstract:Objective To analyze the role of suppressor of cytokine signaling 4 (SOCS4) in the proliferation and migration of esophageal squamous cell carcinoma (ESCC) , and to explore the relationship between the Cullin-RING ubiquitin E3 ligase 5 (CRL5) and Shc1 SH2.domain binding protein (SHCBP1) . Methods The proliferation and migration of ESCC Eca-109 cells were detected by CCK8 assay, clone formation assay, scratch assay and transwell assay. Co-immunoprecipitation combined with mass spectrometry was used to detect proteins interacting with SOCS4. Results SOCS4 was highly expressed in ESCC (P<0.01) and negatively correlated with prognosis (P=0.048) . High-expression of SOCS4 promoted the proliferation and migration of ESCC Eca-109 cells (t=2.503,P=0.046) . SOCS4 interacted with CRL5 and SHCBP1 and promoted SHCBP1 ubiquitination (P<0.001) . Knockdown of SHCBP1 inhibited the proliferation and migration of ESCC Eca-109 cells (Day2: F=7.903,P=0.005; Day3: F=11.569,P<0.001; Day4: F=3.894,P=0.043) . Knockdown of SHCBP1 reversed the promoting effect of SOCS4 on the proliferation and migration of ESCC Eca-109 cells (Day3: F=7.343,P=0.030). Conclusion Patients with high SOCS4 expression have poor prognosis. SOCS4 promotes the proliferation and migration of ESCC by ubiquitinating SHCBP1.
