中文摘要
用废骨中的骨细胞进行的全基因组筛选显示BK通道基因上调。RT-PCR显示骨细胞表达KCNMB 1、2和4亚基基因。制备CaK-GFP转基因小鼠,再制备Col 1a 1-mRFP 1; CaK-GFP双半转基因小鼠。我们正在尝试使用共聚焦显微镜对这些小鼠中的成骨细胞和破骨细胞进行实时成像,当给予BK通道开放剂或阻断剂时。
英文摘要
Genome-wide screening using osteocytes in disused bone showed upregulation of BK channel genes. RT-PCR revealed that osteocytes express KCNMB1, 2 and 4 subunit genes. CaK-GFP transgenic mice were generated, and then Col1a1-mRFP1; CaK-GFP double hemi-transgenic mice were produced. We are trying live imaging of osteoblasts and osteclasts in these mice using confocal microscope when BK channel opener or blocker reagents are administered.
