MicroRNAs are ubiquitous, short, non-coding RNA molecules that function as post-transcriptional regulators of gene expression in a variety of biological processes. In order to further our understanding of the microRNA hierarchy in the reproductive axis of male teleosts, four small RNA libraries were constructed, and sequenced from the testis and brain of(More)
Infectious salmon anaemia virus (ISAV) is an orthomyxovirus causing high mortality in farmed Atlantic salmon (Salmo salar). The collective data from the Atlantic salmon-ISAV interactions, performed "in vitro" using various salmon cell lines and "in vivo" fish infected with different ISAV isolates, have shown a strong regulation of immune related transcripts(More)
Despite the high prevalence and impact to Chilean salmon aquaculture of the intracellular bacterium Piscirickettsia salmonis, the molecular underpinnings of host-pathogen interactions remain unclear. Herein, the interplay of coding and non-coding transcripts has been proposed as a key mechanism involved in immune response. Therefore, the aim of this study(More)
The infectious salmon anemia virus (ISAV) is a severe disease that mainly affects the Atlantic salmon (Salmo salar) aquaculture industry. Although several transcriptional studies have aimed to understand Salmon-ISAV interaction through the evaluation of host-gene transcription, none of them has focused their attention upon the viral transcriptional(More)
Despite evidence for participation in the host response to infection, the roles of many long non-coding RNAs (lncRNAs) remain unknown. Therefore, the aims of this study were to identify lncRNAs in Atlantic salmon (Salmo salar) and evaluate their transcriptomic regulation during ISA virus (ISAV) infection, an Orthomyxoviridae virus associated with high(More)
Despite the increasing evidence of the importance of microRNAs (miRNAs) in the regulation of multiple biological processes, the molecular bases supporting this regulation are still barely understood in crustaceans. Therefore, the molecular characterization and transcriptome modulation of the miRNA biogenesis pathway were evaluated in the salmon louse(More)
MicroRNAs (miRNAs) are small non-coding RNAs that have emerged as key regulators in diverse biological processes across taxa. However, despite the importance of these transcripts, little is known about their role during the immune response in salmonids. Because of this, we use deep sequencing technologies to explore the microRNA-based transcriptomic(More)
One of the largest detriments in the abalone aquaculture industry is the inherently low growth rate of this marine gastropod. In order to confront this issue, greater molecular knowledge is needed on growth traits. Therefore, transcriptome analyses were performed using RNA-Seq for groups of California red abalones (Haliotis rufescens) cultured under the(More)
The genomic era has increased the research effort to uncover how the genome of an organism, and specifically the transcriptome, is modulated after interplaying with pathogenic microorganisms and ectoparasites. However, the ever-increasing accessibility of sequencing technology has also evidenced regulatory roles of long non-coding RNAs (lncRNAs) related to(More)
