TL;DR: The current status of the knowledge about the role of miRNA in development, growth, and physiology of teleost fishes, in comparison to other vertebrates is presented.

TL;DR: This work has determined the expression profiles of 6 candidate reference genes (Actb, Eef2, Fau, Gapdh, Tubb2 and 18S rRNA) in 6 embryonic and 5 larval stages of Atlantic halibut development and determined the best two-gene normalization factors corresponded to the geometric average of Tubb 2/Actb and Tbb2/Fau.

TL;DR: Investigation of changes in quantitative parameters of Atlantic halibut semen throughout the reproductive season found that spermatozoa concentration increases in a linear-like mode towards the end of the spawning season, which correlated with a decrease in a number of spermutozoa motility parameters, including actual percentage of motile spermatozosa (MOT), curvilinear velocity (VCL) and straight-line velocity(VSL) of spermarozoa.

TL;DR: The effect of suppressing aromatase cytochrome P450 enzyme on miRNA expression at the onset of sex differentiation through masculinization with Fadrozole or 17-α-methyltestosterone is investigated to give a first insight into miRNA involvement in sexual development in teleosts.

TL;DR: It is revealed that nucleotide truncations and/or additions at the 3' end of mature miRNAs resulted in size variants showing differential expression patterns during the development in a number of miRNA families.
