Restoration of ODC expression in the HL60-ODC cells resulted in rescue of rottlerin-induced apoptosis of HL60 cells. Simultaneously, phosphothreonine-ODC of rottlerin-treated HL60-ODC cells was highly elevated comparing with HL60-pcDNA3 cells. Taken together, we suggested that rottlerin, a PKCd inhibitor, might decrease phosphothreonine-ODC to reduce both protein stability and enzyme activity of ornithine decarbooxylase and finally resulted in cell apoptosis.
为了侦测鸟胺酸去羧化是否能够负调节rottlerin所引发的细胞凋亡,我们将具有鸟胺酸去羧化cDNA载体稳定转染至HL60细胞内,此细胞称为HL60-ODC细胞,另转染载体的细胞称为HL60-pcDNA3细胞;实验发现HL60-ODC细胞中的鸟胺酸去羧化蛋白为HL60-pcDNA3细胞与HL60细胞表现之2.5倍,同时HL60-ODC细胞提升鸟胺酸去羧化蛋白表现,能够减少rottlerin造成之细胞凋亡现象,并且此蛋白在HL60-ODC细胞中酥胺酸磷酸化较HL60-pcDNA3细胞表现高。

Our data are showed that apoptosis parameters including DNA fragmentation, nuclear morphological change and sub-G1 fraction, appeared after 24 h by 5 μM rottlerin treatment. Furthermore, rottlerin caused a decrease in 72% of ODC protein expression and an increase in threonine, rather than serine and tyrosine dephosphorylation on ODC enzyme compared with the control after incubation for 10 h. To determine whether ODC could down-regulate rottlerin-induced apoptosis, HL60 cells were stably transfected with ODC cDNA. HL60-ODC cells exhibited a 2.5-fold increase in ODC protein compared with vector only (HL60-pcDNA3) or HL60 cells.
在我们筛选天然化合物实验中,发现rottlerin抑制鸟胺酸去羧化活性最具成效,之前的研究人员已知蛋白激Cd调节鸟胺酸去羧化的活性,因此在人类白血病HL60细胞处理rottlerin的实验中发现加入rottlerin二十四小时后,细胞进行计划性死亡,并可侦测到DNA片段、细胞核浓缩及sub-G1提增;而细胞处理药物十小时后与控制组细胞比较,观察到鸟胺酸去羧化的蛋白表现与活性下降50﹪以上;除此以外,测定鸟胺酸去羧化去磷酸化的情况,发现於酥胺酸位置有显著差异,而丝胺酸和酪胺酸位置并无差异。
