Estrogens, as the main female steroid hormones have multiple proven effects on reproductive and non- reproductive systems. Expression of ERα and ERβ, two dominant estrogen receptors, in peripheral blood mononuclear cells in certain B-cell malignancies and the existence of estrogens receptors on mitochondria is open to question that estrogen likely has an impact on the cancerous lymphocytes life span. Acute Lymphoblastic Leukemia (ALL) is the frequent pediatric malignity which is recurrent and hardly curable in many cases. The malignant cells are generally resistant to apoptosis caused the severe lymphocytes accumulation in the peripheral blood.
By focusing on mitochondria as a life/death center of the cell; in the current research we compared cytotoxicity effects of a new ferrocenyl derivative with raloxifene as well-known SERMs considering the apoptotic process and survival of cancerous lymphocytes.
We demonstrated that both ferrocenyl derivative and raloxifene could cause mitochondrial lesion and initiate the apoptosis process by caspase activation and cytochrome c release.
In brief, the ferrocenyl derivative could induce estrogen-related selective apoptosis on cancerous lymphocytes by affecting mitochondrial receptors.
雌激素作为主要的女性甾体激素,已被证实对生殖系统和非生殖系统具有多种作用。在某些B细胞恶性肿瘤中,两种主要的雌激素受体ERα和ERβ在外周血单核细胞中的表达以及线粒体上雌激素受体的存在情况尚存在疑问,即雌激素可能对癌细胞的淋巴细胞寿命产生影响。急性淋巴细胞白血病(ALL)是常见的儿科恶性肿瘤,在许多情况下具有复发性且难以治愈。恶性细胞通常对凋亡具有抗性,导致外周血中淋巴细胞严重积聚。
在当前研究中,我们将细胞的生死中心——线粒体作为研究重点,比较了一种新型二茂铁衍生物与知名选择性雌激素受体调节剂(SERM)雷洛昔芬对癌细胞淋巴细胞凋亡过程和存活情况的细胞毒性作用。
我们证明,二茂铁衍生物和雷洛昔芬均可导致线粒体损伤,并通过半胱天冬酶激活和细胞色素c释放引发凋亡过程。
简而言之,二茂铁衍生物可通过影响线粒体受体诱导癌细胞淋巴细胞发生雌激素相关的选择性凋亡。
