High-content imaging and analysis to quantify the nuclear to cytoplasmic ratio of TGFβ and hippo effectors in mammalian cells

Automated high-content immunofluorescence (IF) microscopy is used to monitor and quantify localization of the TGFβ/Smads and Taz/Yap Hippo effectors in mouse epithelial EpH4 cells transfected with Taz/Yap siRNAs. The nuclear-to-cytoplasmic protein ratios obtained by IF are converted into normalized...

Sumario:Automated high-content immunofluorescence (IF) microscopy is used to monitor and quantify localization of the TGFβ/Smads and Taz/Yap Hippo effectors in mouse epithelial EpH4 cells transfected with Taz/Yap siRNAs. The nuclear-to-cytoplasmic protein ratios obtained by IF are converted into normalized masses by estimating the ratio of the compartment volumes. This method has the advantage that endogenous rather than tagged proteins are tracked and that knockdown of Taz/Yap can be simultaneously monitored at the single-cell level. For complete details on the use and execution of this protocol, please refer to Labibi et al. (2020).
