Effects of agonist and antagonist of cysteinyl leukotriene receptors on differentiation of rat glioma C6 cells / 浙江大学学报·医学版

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the role of cysteinyl leukotriene (CysLT) receptors in the differentiation of rat glioma C6 cells.</p><p><b>METHODS</b>Rat glioma C6 cells were treated with the agonist LTD(4), the CysLT(1) receptor antagonist montelukast and the differentiation inducer forskolin. Cell morphology and GFAP protein expression were determined after treatments.</p><p><b>RESULT</b>Forskolin (10 μmol/L) induced morphological changes and GFAP protein expression (cell differentiation) in C6 cells, but LTD(4) (0.1-100 nmol/L) did not induce these changes. Montelukast (1 μmol/L) alone did not affect C6 cell differentiation, while it induced the differentiation when combined with the LTD(4) (100 nmol/L).</p><p><b>CONCLUSION</b>The CysLT(2) receptor may modulate the differentiation of rat glioma C6 cells.</p>
