Accumulating evidence suggests that cardiac progenitor specification is subject to transcriptional control beyond the level of transcription initiation. The PAF1C component Rtf1 is a multifunctional transcription regulatory protein that modulates pausing and elongation of RNA Pol II as well as histone epigenetic modifications. By transient knockdown and CRISPR mutagenesis we found that Rtf1 is essential for cardiogenesis and that without xxx activity cardiac progenitors arrest in an immature state. This role in early cardiogenesis was evolutionarily conserved between fish and mammals. We also found that Rtf1's Plus3 domain which confers interaction with the pausing/elongation factor Spt5 was required for Rtf1's ability to support cardiac progenitor formation while other regions of the protein were dispensable. We examined the occupancy of RNA Pol II at cardiac genes in rtf1 morphants using ChIP seq and found that Pol II signals at the TSS of genes was reduced suggesting a reduction in transcriptional pausing. Intriguingly pharmacological or morpholino antisense reduction of pause release in rtf1 morphants and mutants restored the formation of cardiac cells and improved Pol II occupancy at the TSS of key cardiac genes.

The small heat shock protein alpha crystallins evolved to become key components of this lens possibly because of their ability to prevent aggregation of aging protein that would otherwise lead to lens opacity. Most vertebrates express two alpha crystallins alpha A and alpha B crystallin and mutations in each are linked to human cataract. In a mouse knockout model only the loss of alpha A crystallin led to early stage lens cataract. We have used the zebrafish as a model system to investigate the role of alpha crystallins during lens development. Interestingly while zebrafish express one lens specific alpha A crystallin gene cryaa they express two alpha B crystallin genes with one evolving lens specificity cryaba and the other retaining the broad expression of its mammalian ortholog cryabb. In this study we used individual mutant zebrafish lines for all three alpha crystallin genes to determine the impact of their loss on age related cataract. Surprisingly unlike mouse knockout models we found that the loss of the alpha Ba crystallin gene cryaba led to an increase in lens opacity compared to cryaa null fish at 24 month of age. Loss of alpha A crystallin did not increase the prevalence of cataract. We also used single cell RNA Seq and RT qPCR data to show a shift in the lens expression of zebrafish alpha crystallins between 5 dpf and 10 dpf dpf with 5 dpf and 6 dpf lenses expressing cryaa almost exclusively and expression of cryaba and cryabb becoming more prominent post 10 dpf. These data show that cryaa is the primary alpha crystallin during early lens development while the protective role for cryaba becomes more important during lens aging. This study is the first to quantify cataract prevalence in wild type zebrafish showing that lens opacities develop in approximately 25% of fish by 18 month of age. None of the three alpha crystallin mutants showed a compensatory increase in the expression of the remaining two crystallins or in the abundant beta B1 crystallin. Overall these findings indicate an ontogenetic shift in the functional importance of individual alpha crystallins during zebrafish lens development.

The small heat shock protein alpha crystallins evolved to become key components of this lens possibly because of their ability to prevent aggregation of aging protein that would otherwise lead to lens opacity. Most vertebrates express two alpha crystallins alpha A and alpha B crystallin and mutations in each are linked to human cataract. In a mouse knockout model only the loss of alpha A crystallin led to early stage lens cataract. We have used the zebrafish as a model system to investigate the role of alpha crystallins during lens development. Interestingly while zebrafish express one lens specific alpha A crystallin gene cryaa they express two alpha B crystallin genes with one evolving lens specificity cryaba and the other retaining the broad expression of its mammalian ortholog cryabb. In this study we used individual mutant zebrafish lines for all three alpha crystallin genes to determine the impact of their loss on age related cataract. Surprisingly unlike mouse knockout models we found that the loss of the alpha Ba crystallin gene cryaba led to an increase in lens opacity compared to cryaa null fish at 24 month of age. Loss of alpha A crystallin did not increase the prevalence of cataract. We also used single cell RNA Seq and RT qPCR data to show a shift in the lens expression of zebrafish alpha crystallins between 5 dpf and 10 dpf dpf with 5 dpf and 6 dpf lenses expressing cryaa almost exclusively and expression of cryaba and cryabb becoming more prominent post 10 dpf. These data show that cryaa is the primary alpha crystallin during early lens development while the protective role for cryaba becomes more important during lens aging. This study is the first to quantify cataract prevalence in wild type zebrafish showing that lens opacities develop in approximately 25% of fish by 18 month of age. None of the three alpha crystallin mutants showed a compensatory increase in the expression of the remaining two crystallins or in the abundant beta B1 crystallin. Overall these findings indicate an ontogenetic shift in the functional importance of individual alpha crystallins during zebrafish lens development.
