  1. ...-type/lineage-specific marker genes, and characterize transitions of cellular transcriptional states during zebrafish caudal fin regeneration (Hou et al. 2020; Jiang et al. 2021; Tang et al. 2022; Lewis et al. 2023; Cudak et al. 2024). Similar approaches have been applied in other regenerative contexts, such as the zebrafish...
  2. ...revealed thousands of sex-biased genes in mammals and birds (Yang et al. 2006; Itoh et al. 2010; Harrison et al. 2015; Melé et al. 2015). Less attention has been given to the potential impact of sex-biased microRNAs (miRNAs)—short regulatory RNAs (∼21 nt) that enable expression fine-tuning of target m...
  3. ...a challenging task. Transcription is regulated through complex interactions between trans-acting factors and cis-acting elements. Genes are typically associated with multiple cis-acting elements, which can refine their expression levels, control different expression domains, or confer robustness through partial...
  4. ...expression play key roles in early evolutionary divergence (King and Wilson 1975). In support of that, modifying the expression of a single, differentiation-promoting gene during organism development can give rise to novel body morphologies (Warren et al. 1994; Prud'homme et al. 2006). Although transcription...
  5. ...,B; Supplemental Fig. S8). This is particularly striking for ORIs in Polycomb chromatin (state 5) and to a lesser extent in the AT-rich heterochromatin (state 8), where a strong enhancement of transcription in 4-d-old seedlings was observed. The opposite happens for the active regions of long genes (state 7...
  6. ...abundances (eight and three genes changing greater than twofold in calorie-rich and rapamycin media, respectively) (Fig. 5A,B). The known low oxygen responders TIR1 and ANB1 (Lowry and Lieber 1986; Cohen et al. 2001) were repressed by oxygen (i.e., in WA-HPF1). Five of the six transcripts induced...
  7. ...generate genomic raw material that allows the emergence of novel functions, likely facilitating adaptive evolutionary innovations. However, global assessments of the functional and evolutionary relevance of duplicate genes in mammals were until recently limited by the lack of appropriate comparative data...
  8. ...no consensus on a quantitative framework for addressing the functional questions related to evolution of expression levels, due in part to a lack of agreement for how to best model expression evolution in mammals. In Drosophila, studies have found that unlike sequence evolution, divergence of gene expression...
  9. ...autosomes through cross-species sequence alignments. As miRNA targeting occurs post-transcriptionally, reconstruction of its ancestral state is decoupled from transcriptional regulatory mechanisms such as XCI that evolved following X-Y differentiation.ResultsAnalysis of human copy number variation indicates...
