Evaluating Modulators of “Regulator of G‐protein Signaling” (RGS) Proteins

?protein Signaling? (RGS) proteins constitute a class of intracellular signaling regulators that accelerate GTP hydrolysis by heterotrimeric G? subunits. In recent years, RGS proteins have emerged as potential drug targets for modulation by small molecules

用经超滤的样本，而检测高分子量肽片段用未超滤的样本即可。5ml样本溶液与5ml基质溶液混合，取1ml混合液贮存于不锈钢容器中作质谱分析。外部质定标用质荷比（m/z）分别为5734和2867的牛胰岛素的[M+H]+和[M+H]2+离子。为了验证分析的精确性，每份样本进行3次独立分析。 9. 统计分析 统计分析采用Student’t检验、Wilcoxon检验和Fisher精密检验，小于5％为显著性检验标准。 结 果 胰腺癌患者和慢性胰腺炎患者间肝脏组织乳酸盐、葡萄糖、亚硝酸盐、硝酸盐、GAPDH酶活
