Calcium sulfate has been used for bone regenation in oral medicine. Osteopontin, a marker molecule, expressed by osteoblast, plays multiple roles in human body. However, the effect of calcium sulfate on osteopontin expressed in osteoblasts is unclear. In this study, U-2 osteosarcoma osteoblastic cells were cultured in 0, 0.5, 1, or 10 μM calcium sulfate hemihydrate. There was no effect in the proliferation of cells, suggesting that calcium sulfate up to 10 μM is biocompatible. The cells and conditioned media were collected for analyzing mRNA and protein levels of osteopontin by reverse-transcription polymerase chain reaction and Western blot, respectively.
硫酸钙用於口腔医学中的骨头再生已经有多年历史,骨桥素是一种被骨母细胞分泌且在人体扮演重要多重角色的标的分子,然而,硫酸钙在骨母细胞分泌硫酸钙上的影响仍未明朗,在本实验之中,培养U-2骨肉瘤类骨母细胞(U-2 osteosarcoma osteoblastic cells)於0、0.5、1、10 μM的硫酸钙之中,在细胞数目的复制上,四种硫酸钙浓度并无影响,显示出U-2骨肉瘤类骨母细胞培养於10 μM的硫酸钙仍是生物相容性的。

In our study, we found menadione has anticancer potential on human breast adenocarcinoma MDA MB 231 by weather cell cycle arrest, anti proliferation, or apoptosis. Low concentration of menadione (5.8μM) significant inhibited growth curve on breast cancer cells (MDA MB 231) but not breast cells (MCF 10A) by performing MTT and trypan blue cell counting. RT-PCR and western blotting showed menadione increase p21 gene and protein expressions but decrease cyclin E and CDK2 protein expression resulting in cell cycle G0/G1 arrest by flow cytometry.
MTT及生长曲线的实验,发现menadione在低浓度且长时间作用情况下,对在於人类乳腺上皮细胞癌(MDA-MB 231)是有明显的抑制作用,而在正常乳腺细胞(MCF-10A)则没有影响,在分子转录上及蛋白质表现方面也发现低浓度menadione处理24时能使MDA-MB 231诱发p21基因及蛋白表现量增加及cyclin E、CDK2抑制,再经由流式细胞仪分析也发现低浓度 menadione 处理24小时能使MDA-MB 231细胞周期GO/G1比例上升,造成细胞周期停滞,进而抑制细胞生长。
