Project description:Migration is essential for the reproduction and survival of many animals, yet little is understood about its underlying molecular mechanisms. We used the salmonid Oncorhynchus mykiss to gain mechanistic insight into smoltification, which is a morphological, physiological, and behavioral transition undertaken by some juveniles that culminates in a seaward migration. This species is experimentally tractable and, unlike common model species, displays intra- and inter-population variation in migration propensity. Migratory individuals can produce non-migratory progeny and vice versa, indicating a high degree of phenotypic plasticity. One potential way that phenotypic plasticity might be linked to variation in migration-related life history tactics is through epigenetic regulation of gene expression. To explore this, we quantitatively measured genome-scale DNA methylation in fin tissue using reduced representation bisulfite sequencing of F2 siblings produced from a cross between steelhead (migratory) and rainbow trout (non-migratory) lines. We identified 57 differentially methylated regions (DMRs) between smolt and resident O. mykiss juveniles. DMRs were of high magnitude, ranging from 20-62% differential methylation between life history types, and over half of the gene-associated DMRs were in transcriptional regulatory regions. Many of the DMRs encode proteins with activity relevant to migration-related transitions (e.g. circadian rhythm pathway, nervous system development, protein kinase activity). This study provides the first evidence of a relationship between epigenetic variation and life history divergence associated with a migration-related transition in any species.

Project description:This 121-node Boolean regulatory network model that synthesizes mechanosensitive signaling that links anchorage and matrix stiffness to proliferation and migration, and cell density to contact inhibition. It can reproduce anchorage dependence and anoikis, detachment-induced cytokinesis errors, the effect of matrix stiffness on proliferation, and contact inhibition of proliferation and migration by two mechanisms that converge on the YAP transcription factor. In addition, this model offers testable predictions related to cell cycle-dependent sensitivity to anoikis, the molecular requirements for abolishing contact inhibition, substrate stiffness-dependent expression of the catalytic subunit of PI3K, heterogeneity of migratory and non-migratory phenotypes in sub-confluent monolayers, and linked inhibition but semi-independent induction of proliferation versus migration as a function of cell density and mitogenic stimulation.
The model is an extended version of the growth signaling, cell cycle and apoptosis model published in Sizek et al, PLoS Comp. Biol. 15(3): e1006402, 2019.
