| 靶点 | Topoisomerase |
| 通路 | DNA Damage/DNA Repair |
| 背景说明 | (±)-10-Hydroxycamptothecin 是一种生物碱，能够抑制拓扑异构酶 I (topoisomerase I) 的活性，具有广谱的抗肿瘤活性。 |
| 生物活性 | (±)-10-Hydroxycamptothecin is an indole alkaloid that inhibits the activity of topoisomerase I and has a broad spectrum of anticancer activity.[1-3] |
| In Vitro | (±)-10-Hydroxycamptothecin (10-OH-camptothecin) is an inhibitor of topo I[1]. (±)-10-Hydroxycamptothecin (10-HCPT， 5-20 nM) markedly inhibits the proliferation of Colo 205 cells in a dose-dependent manner. (±)-10-Hydroxycamptothecin (5-20 nM) arrests Colo 205 cells in the G2 phase of the cell cycle and triggers apoptosis through a caspase-3-dependent pathway[2]. (±)-10-Hydroxycamptothecin (HPT， 0.01-10 μg/mL) causes cell shrinage， nuclear fragmentation and condensed chromosomes and induces apoptosis of human urinary bladder cancer cell line (T24)[3]. |
| In Vivo | (±)-10-Hydroxycamptothecin (10-HCPT， 2.5-7.5 mg/kg/2 days， p.o.) significantly suppresss tumor growth in mouse xenografts. (±)-10-Hydroxycamptothecin (1-7.5 mg/kg， p.o.， once per 2 or 4 days) causes no obvious acute toxicity in nude mice[2]. |
| 细胞实验 | Colo 205 cells (5 × 105) (ATCC: CCL-222) are seeded in 25T flasks overnight and then treated without (control) and with 5， 10， 15 or 20 nM of (±)-10-Hydroxycamptothecin， respectively. After treatment for 24-120 h， cells are harvested by trypsin-EDTA and then centrifuged at 1，500 rpm for 5 min at 4?C. The cell pellet is resuspended in culture medium containing 0.04% trypan blue and the viable cells are enumerated by a hemocytometer[2]. |
| 动物实验 | BALB/c-nu mice are housed in a laminar flow room under sterilized conditions with a maintained temperature of 25 ± 2?C and a controlled 12-h light and 12-h dark cycle. The Colo 205 cells are harvested and resuspended in serum-free RPMI-1640 medium. Cells are adjusted to 1 × 107 cells/mL， and transplanted 0.1 mL subcutaneously to the flank regions of the mice. Each experimental group included six to seven mice bearing tumors. (±)-10-Hydroxycamptothecin is dissolved in propylene glycol and treatment begins when the tumor size reach 3-5 mm. (±)-10-Hydroxycamptothecin is administered via p.o. once per two or four days at doses of 1， 2.5， 5， 7.5 mg/kg (volume of injection: 0.1 mL/20 g of body weight)， respectively. The control group receives propylene glycol vehicle once per two days. Tumor size and body weight are monitored twice a week throughout the experiment. The tumor size is measured using a vernier caliper. Tumor volume (V) is calculated according to the formula: V (mm3) = 0.4AB2， where A and B are the longest diameter and the shortest diameter， respectively. At the end of the experiment， all mice are sacrificed by CO2 gas. Tumors， livers， kidneys and lungs are collected， fixed， embedded and stained with hematoxylin and eosin for pathological analysis[2]. |

麻醉家兔、大鼠左室内压（LVP）与左室内压变化速率（±dp/dtmax）的测定
心脏左心室内压（left ventricular pressure LVP）及其变化速率，是反映和评价左心室收缩功能与舒张功能的重要指标，不论是在临床的心导管检测，还是在基础医学的实验教学与科研中经常要用到这一测量方法。一般情况下，家兔、大鼠均采用通过颈总动脉插管到达心脏左心室的方法，即可获得反映左心室收缩功能与舒张功能的指标，而且操作简便、易行。另外大鼠还可以采用经左心室心尖部插管到达左心室，测量反映左心室收缩功能与舒张功能指标的方法。这一测量方法，可以在测量左心
及二批以上的数据，我们只需增加 Y 轴的数量即可，然后选择图形需要显示的类型，如平均值加减标准误（Mean±SEM），软件会自动计算数据并显示。而如果我们已经通过其它软件计算好平均值，标准差或标准误等，也可将对应数据输入，软件也能根据数据做出对应图。推荐大家使用前两种，直接输入原始数据，简单方便，下面我们就一起来体会下 GraphPad Prism 的便捷吧！我们以曲线图为例，选择输入三批重复数据，并且数据以平均值加减标准误（Mean±SEM）显示：我们通过新建一个数据表格后，将三批数据输入（只需
技术。成像系统的分辨率受到阿贝衍射极限的限制，存在接近波长一半尺度的衍射极限，物场信息中高于此光学传递函数截止频率的成分将会被滤除。针对这一问题，Gustafsson 于 2000 年提出了 SIM 技术，其基本原理是通过结构化照明在频域以空间混频的方式将物体高频信息载入光学系统的探测通带内实现突破阿贝衍射极限的超分辨光学显微成像。当利用周期性结构正弦照明光激发样品时，在频域上由于结构光频谱与物频谱的卷积而产生携带物体信息的多级频谱。其中±1 级频谱将携带物体细节信息的高频部分平移至截止频率范围
