KCNJ5
KCNJ5,全稱為鉀通道亞家族J成員5,常用別名包括Kir3.4。KCNJ5能在細胞表面形成鉀離子通道,調控鉀離子的跨膜流動,維持細胞正常的電生理狀態與功能平衡。在腎上腺皮質細胞中,KCNJ5結構或功能異常會打破醛固酮分泌的穩定,導致體內鹽與水的代謝失衡,進而引發血壓升高。臨床上,家族性醛固酮增多癥Ⅲ型就與該蛋白的突變直接相關,患者常面臨難治性高血壓和低血鉀的困擾。目前針對這個蛋白的藥物研發正逐步推進,一些靶向調節其通道活性的化合物,有望通過糾正醛固酮的異常分泌,為這類高血壓患者提供更精準的治療方案,相關研究也在持續探索其臨床應用價值。

IHC image of CSB-PA012058LA01HU diluted at 1:300 and staining in paraffin-embedded human adrenal gland tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
Immunofluorescence staining of A549 cells with CSB-PA012058LA01HU at 1:100, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
