摘要

Chemoresistance is a common property of tumor-initiating cancer stem-like cells. Overcoming chemoresistance, particularly in cancer stem-like cells, can markedly enhance the efficacy of cancer therapy and prevent cancer recurrence and metastasis. This study demonstrates that temperature-negative expansion nanodrugs could achieve the controllable and enhanced release of anticancer drugs when combined with cryoablation and effectively overcome chemoresistance in mammary cancer stem-like cells. The enhanced destruction of both cancer stem-like cells and cancer cells resulted in the improved inhibition of second-generation tumor formation in vitro. Furthermore, nanodrug-mediated cryosurgery did not produce systemic toxicity and had superior antitumor effects in a xenograft tumor model. Collectively, this study demonstrates the strong potential of thermally sensitive nanodrug-mediated cryoablation for overcoming chemoresistance in cancer stem-like cells and markedly improving the overall treatment efficacy against breast cancer.

在Journal of Materials Chemistry B的封面中，出现了多彩的螺旋线，那这样的多彩螺旋线是如何实现的呢，本次课程就跟着图研科技一起来学习如何用Maya的螺旋线做出DNA链堆积的纳米球。

1.打开Maya软件，新建一个螺旋线。

2.根据需要，调节螺旋线的参数。

3.切换到面模式，给螺旋线四个不同的材质用不同颜色标出。

4.新建一个柏拉图多面体，调节其参数。

5.选择螺旋线，按mash按钮。

6.调节mash的参数，分布类型选择网格，方式为面中心，沿发现推动为2，输入网格为之前新建的柏拉图多面体，勾选泛洪网格按钮。

7.一个纳米球就做好了，给其灯光就可以渲染了。

结语：

对于科研工作者而言，做出优秀的科研成果的同时，将抽象、严谨的深奥知识，通过直观、形象的方式表现出来，找到有章可循的表达方式为自己的科研成果锦上添花十分重要，想要精准提升作图技能，科研绘图私教课火热报名中！
