TL;DR: This study characterized miRNAs and their expression in Poecilia mexicana, a species of small fish that inhabits both normal streams and extreme environments in the form of springs rich in toxic hydrogen sulphide (H2S), and identified a large population of mature miRNA genes that were differentially expressed between locally adapted populations in contrasting habitats, indicating that miRN as may contribute to P. mexicaana adaptation to sulphidic environments.

TL;DR: The majority of variation in gene expression was correlated with organ type, and the presence of specific environmental stressors elicited unique expression differences among organs, potentially indicating that physiochemical stressors with clear biochemical consequences can constrain the diversity of adaptive solutions that mitigate their adverse effects.

TL;DR: Comparing populations of fish that have independently adapted to hydrogen-sulfide-rich environments in southern Mexico to adjacent populations residing in nonsulfidic waters concludes that considering both differential expression and changes in DNA sequence led to a more comprehensive understanding of how these populations adapted to extreme environmental conditions.

TL;DR: Emerging evidence supporting a critical role of ten-eleven translocation 1 (TET1) in mediating epigenetic processes leading to dysregulation of molecular processes and functions is reviewed.
