A small RNA sequencing dataset from multiple tissues of Orestias ascotanensis collected at two seasonal time points

ABSTRACT: This study presents a small RNA sequencing (small RNA-seq) dataset from the Andean killifish Orestias ascotanensis, an extremophile teleost endemic to the Ascotán Salt Pan in the Chilean Altiplano. The dataset includes 42 libraries generated from gills, skin, and muscle tissues of 14 adult individuals sampled in summer and winter. Small RNA libraries were prepared using the Illumina TruSeq Small RNA Library Preparation Kit and sequenced on an Illumina NextSeq 500 platform

Seasonal tissue-specific transcriptomic responses of the Andean Killifish Orestias ascotanensis

Project description:The Andean killifish Orestias ascotanensis inhabits the high-altitude Ascotán Salt Pan, an environment with variable salinity, high UV exposure, low oxygen, and extreme daily temperature fluctuations. These conditions make it an excellent model for studying high-altitude fish biology. However, the transcriptomic responses of O. ascotanensis to seasonal acclimation remain unexplored. To investigate seasonal and tissue-specific transcriptomic profiles, RNA-seq was performed on 42 libraries from gills, skin, and muscle tissues of 14 individuals collected in summer (n=7) and winter (n=7). Each library had a median of 105 million reads. Principal component analysis revealed strong tissue-specific expression, and seasonal differential expression analyses identified significant transcriptomic changes within each tissue. Additionally, a bioinformatics pipeline identified 10,365 high-confidence long non-coding RNAs (lncRNAs), predicted by at least three computational tools. Compared to protein-coding genes, lncRNAs exhibited higher tissue specificity, with a predominance of monoexonic structures and shorter exon lengths. This dataset provides the first comprehensive view of seasonal mRNA and lncRNA expression in O. ascotanensis tissues.

Profiling microRNA expression in Atlantic killifish (Fundulus heteroclitus) gill and responses to arsenic and hyperosmotic stress

Project description:The Atlantic killifish (Fundulus heteroclitus), native to estuarine areas of the Atlantic coast of the United States, has become a valuable ecotoxicological model due to its ability to acclimate to rapid environmental changes and adapt to polluted habitats. Killifish respond to rapid increases in salinity with an immediate change in gene expression, as well as long-term remodeling of the gills. Arsenic, a major environmental toxicant, was previously shown to inhibit the ability of killifish gill to respond to a rapid increase in salinity. We characterized miRNA expression in killifish gill under salinity acclimation with and without arsenic and identified a small group of highly expressed, well-conserved miRNAs as well as 16 novel miRNAs not yet identified in other organisms.

Expression analysis of Fudulus heteroclitus populations exposed to arsenic during hypo-osmotic shock

Project description:Gene expression was measured in the gills of saltwater (SW) acclimated Atlantic Killifish, Fundulus heteroclitus, over a time course of freshwater (FW) exposure, in which half the fish were exposed to arsenic. Fish were sampled from three populations, two from Maine, USA (ME) and one from Virginia, USA (VA)
