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 iii) it complements more conventional cancer assay data such as invasion, migration and adhesion.
Background
Determining the therapeutic utility of any biological molecule is a critical step in the development of novel molecular therapeutics to combat cancer progression and development. As a preliminary step in in vitro characterization, molecules must be assessed for their suitability as anti-cancer therapeutics. As part of this assessment, cell viability is a critical determinant of the cellular response to small molecules as it reflects the ability of a molecule to sustain a threshold cell viability, whilst simultaneously targeting key cancer progression mechanisms e.g., clonogenicity, invasion and adhesion. Conventional viability assays require an intensive labor input comprising microscopy, hemocytometers and manual cell counters. Here we developed a protocol for the rapid and accurate generation of cell viability data that will complement cancer research studies (Phelan et al., 2016).
