methods: (1)immunofluorescence and electron microscopic autoradiography(em-arg) were used to detect the expression and distribution of somatostatin receptor 2 subtype in nci-h446 cells.
somatostatin or somatostatin receptor 2 agonist can inhibit the nocturnal secreting peak of growth hormone and glucagon, therefore avoid dawn phenomenon.
也可应用生长抑素抑制夜间胰高糖素和生长激素的分泌高峰,避免「黎明现象」的发生。
aim: to construct recombinant adenovirus vector carrying the gene of human somatostatin receptor type 2 (sstr2) for gene therapy of pancreatic carcinoma.
目的:构建表达sstr2的重组腺病毒载体,用于胰腺癌的基因治疗。
conclusions a higher label rate can be acquired without practicing further purification procedures with this method. thus, it is applicable to scintigraphy of tumor somatostatin receptor (sstr).
结论此方法标记奥曲肽有较高的标记率,无需进一步纯化,可用于肿瘤生长抑素受体显像。
objective to investigate the expressions of somatostatin receptor 2 (sstr2) subtype in the cell line of nci-h446 and normal lung tissue of nude mice.
