[Abstract] Cell viability assays are an essential aspect of most cancer studies, however they usually require a considerable labor and time input. Here, instead of using the conventional microscopy and hemocytometer cell counting approach, we developed a cell harvesting protocol and combined it with the automated Countess Automated Cell Counter to generate cell viability data. We investigated the effects of dihydroxylated bile acids on the cell viability of prostate cancer cells grown under hypoxic conditions. We observed that for all conditions, cell viability was relatively unchanged, suggesting these molecules had little or no impact on cell viability. The combination of the automated approach and the cell harvesting protocol means this assay is i) easy to perform, ii) extremely reproducible and ...
[摘要] 细胞活力测定是大多数癌症研究的一个重要方面，然而，它们通常需要相当多的劳动和时间投入。在这里，而不是使用常规的显微镜和血细胞计数细胞计数方法，我们开发了一个细胞收获协议，并结合自动Countess自动细胞计数器生成细胞活力数据。我们调查二羟基化胆汁酸对缺氧条件下生长的前列腺癌细胞的细胞活力的影响。我们观察到，对于所有条件，细胞活力相对不变，表明这些分子对细胞活力几乎没有或没有影响。自动化方法和细胞收获方案的组合意味着该测定i）容易实施，ii）极其可重复，和iii）其补充更常规的癌症测定数据例如入侵，迁移和粘附。
[背景] 确定任何生物分子的治疗效用是开发新的分子治疗以抵抗癌症进展和发展的关键步骤。作为体外表征的初步步骤，必须评估分子作为抗癌治疗剂的适合性。作为该评估的一部分，细胞活力是小分子的细胞反应的关键决定因素，因为其反映分子维持阈值细胞活力的能力，同时靶向关键癌症进展机制例如。 ，集落性，侵袭和粘附。常规的生存力测定需要包括显微镜，血细胞计数器和手动细胞计数器的大量劳动输入。在这里，我们开发了快速和准确生成细胞活力数据的协议，将补充癌症研究研究（Phelan等人，2016）。

[Abstract] AlamarBlueTM detects cell viability by utilizing a nonfluorescent dye resazurin, which is converted to a fluorescent dye resorufin in response to chemical reduction of growth medium resulting from cell growth. The fluorescent or colorimetric signal generated from the assay is proportional to the number of living cells in the sample (detailed information can be found from here).
[摘要] AlamarBlueTM通过利用非荧光染料刃天青检测细胞存活力，其响应于由细胞生长产生的生长培养基的化学还原转化为荧光染料试卤灵。 从测定产生的荧光或比色信号与样品中的活细胞数量成比例（详细信息可从这里找到）。

[Abstract] The STAT3 transcription factor is an important signaling molecule for many cytokines and growth factor receptors and is constitutively activated in a number of human tumors and possesses oncogenic potential and anti-apoptotic activities. STAT3 is activated by phosphorylation at Tyr705, which induces dimerization, nuclear translocation, and DNA binding. Western blot is most commonly used to detect the activation of STAT3 by using an antibody that is specific for the phosphorylated tyrosine705.
[摘要] STAT3转录因子是许多细胞因子和生长因子受体的重要信号分子，并且在许多人肿瘤中被组成型激活，并且具有致癌潜力和抗凋亡活性。 STAT3被Tyr705处的磷酸化激活，其诱导二聚化，核转位和DNA结合。 蛋白质印迹最常用于通过使用对磷酸化酪氨酸特异的抗体来检测STAT3的活化。
