最近的研究表明,在施加某些形式的应激(包括热休克)后,多种细胞会产生一组特定的蛋白质。从患有中度至重度骨关节炎的软骨中分离出的人类软骨细胞在生理温度(37°C)下合成至少一种这些应激蛋白(Mr70, 000),而从非病理性软骨中分离出的软骨细胞仅在高于39°C的温度下孵育时合成这种蛋白质。这种蛋白质 (SP-70) 在 37°C 下的主动合成与骨关节炎的严重程度呈正相关,可以作为这种退行性疾病的特征指标。在含有 35S-蛋氨酸的培养基中孵育软骨组织并通过十二烷基硫酸钠-聚丙烯酰胺凝胶电泳分离细胞相关蛋白后,我们鉴定了应激蛋白的主动合成。通过放射自显影使放射性蛋白质可视化。通过用35S-甲硫氨酸脉冲组织来确定细胞相关蛋白的寿命分析,并且在培养基中不同时间的追踪后,通过十二烷基硫酸钠-聚丙烯酰胺凝胶电泳分离蛋白质。然后切除特定的蛋白质条带,并通过液体闪烁计数测定放射性。
Recent studies have shown that a specific set of proteins is produced by a variety of cells after the application of some forms of stress, including heat shock. Human chondrocytes isolated from cartilage with moderate to severe osteoarthritis synthesize at least 1 of these stress proteins (Mr70, 000) at physiologic temperature (37°C), whereas chondrocytes isolated from non‐pathologic cartilage synthesize this protein only in response to incubation at temperatures above 39°C. The active synthesis of this protein (SP‐70) at 37°C is positively correlated with the severity of osteoarthritis and can be a characteristic indicator of this degenerative disease. We identified the active synthesis of stress proteins after incubating the cartilage tissue in medium containing35S‐methionine and separating the cell‐associated proteins by sodium dodecyl sulfate–polyacrylamide gel electrophoresis. The radioactive proteins were visualized by autoradiography. Analysis of the longevity of cell‐associated proteins was determined by pulsing the tissue with35S‐methionine, and after different periods of chase in medium, the proteins were separated by sodium dodecyl sulfate–polyacrylamide gel electrophoresis. Specific protein bands were then excised, and the radioactivity was determined by liquid scintillation counting.
