Genetic interaction analysis by combinatorial genetic perturbation and high-throughput imaging maps time- and context-dependent crosstalk between signaling pathways.
The strength of TCR signalling determines the rate at which cells initiate a tightly coordinated signalling programme, without altering its organization.

NODAL/Activin-induced SMAD2 binding directly drives remodeling of both open and closed chromatin and does not directly correlate with temporal patterns of gene expression upon prolonged signaling.
The exon junction complex regulates the cell polarity determinant Discs large 1, which acts independently from its role in cell polarity to protect Dishevelled protein from lysosomal degradation in Wingless/Wnt signaling.
A systematic genetic analysis comprising seven genome-wide screens in haploid human cells uncovered new regulatory mechanisms at most levels in the WNT signaling pathway.
The requirement for WNT signaling in mesendoderm differentiation is temporally separate from that of ACTIVIN signaling and acts to switch the output of ACTIVIN/SMAD2 from pluripotency maintenance to mesendoderm patterning.

Activation of Wnt/β-catenin signaling in endothelial progenitors derived from human pluripotent stem cells partially induces the specialized blood–brain barrier phenotype while the same treatment in matured endothelial cells is less efficacious.
By controlling the SUMOylation of the protein CAR-1, the aging-regulating pathways downstream of the Insulin/IGF signaling cascade and of the germ cells of the nematode Caenorhabditis elegans are integrated.
