文题释义:
盐霉素:
为一元羧酸聚醚类动物专用抗生素,对大多数革兰阳性菌和各种球虫有较强的抑制和杀灭作用,不易产生耐药性和交叉抗药性,排泄迅速,残留量极低。
乳腺癌:是发生在乳腺腺上皮组织的恶性肿瘤。女性乳腺是由皮肤、纤维组织、乳腺腺体和脂肪组成的,乳腺癌中99%发生在女性,男性仅占1%。由于乳腺并不是维持人体生命活动的重要器官,原位乳腺癌并不致命;但由于乳腺癌细胞丧失了正常细胞的特性,细胞之间连接松散,容易脱落。癌细胞一旦脱落,游离的癌细胞可以随血液或淋巴液播散全身,形成转移,危及生命。

 

摘要
背景:
间充质干细胞分泌的因子所形成的的微环境能够抑制肿瘤细胞的恶性增殖,而盐霉素也对肿瘤细胞生长有抑制作用。
目的:探讨盐霉素联合脐血间充质干细胞干预对乳腺癌MCF-7细胞的影响及作用机制,为乳腺癌的治疗寻找新的靶点和治疗策略。
方法:选取对数生长的MCF-7乳腺癌细胞,将其随机分为对照组、脐血间充质干细胞组及联合组。对照组细胞不做任何处理,干预组加入脐血间充质干细胞悬液,联合组细胞同时加入脐血间充质干细胞悬液和盐霉素。
结果与结论:干预48 h后,与对照组及脐血间充质干细胞组相比,联合组乳腺癌MCF-7细胞的增殖与侵袭能力抑制作用更为明显;细胞中POSTN蛋白的表达水平也较低。提示脐血间充质干细胞与盐霉素联合干预能有效抑制乳腺癌MCF-7细胞的增殖与迁移,为乳腺癌的治疗提出一种新的治疗方法。

Abstract:

BACKGROUND: Mesenchymal stem cells-released factors can form a microenvironment inhibiting malignant tumor cell proliferation, and moreover, salinomycin also inhibits the growth of tumor cells.
OBJECTIVE: To explore the effect of salinomycin with umbilical cord blood mesenchymal stem cells in breast cancer MCF-7 cells and its action mechanism, in order to seek a new target and therapeutic strategy to treat breast cancer.
METHODS: Logarithmically growing MCF-7 cells were randomly divided into control, umbilical cord blood mesenchymal stem cell group and combination group. Cells in the control group were given no treatment, while those in the other two groups were given umbilical cord blood mesenchymal stem cell suspension or umbilical cord blood mesenchymal stem cell suspension combined with salinomycin, respectively.
RESULTS AND CONCLUSION: Forty-eight hours after the intervention, the proliferation and invasion of MCF-7 cells and expression of POSTN protein in cells were significantly reduced in the combination group compared with the other two groups. These findings indicate that the combination of umbilical cord blood mesenchymal stem cell suspension and salinomycin effectively reduces the proliferation and migration of MCF-7 cells, and this combined use provides a new insight into the treatment of breast cancer.
