| Abstract |
Argonaute proteins are key components of the small RNA-induced silencing complex and have multiple roles in RNA-directed regulatory pathways. Argonaute genes can be divided into two subfamilies: the Ago (interacting with microRNA/small interfering RNA) and Piwi subfamilies (interacting with piwi-interacting RNAs (piRNAs)). In the present study, genome-wide analyses firstly yielded the identification of different members of Agos and Piwis in the tilapia, coelacanth, spotted gar, and elephant shark. The additional teleost Ago3b was generated following the fish-specific genome duplication event. Selective pressure analysis on Agos and Piwis between cichlids and other teleosts showed an accelerated evolution of Piwil1 in the cichlid lineages, and the positive selected sites were located in the region of PIWI domain, suggesting that these amino acid substitutions are adapt to targeted cleavage of messenger RNA (mRNA) in cichlids. Ago1 and Ago4 were detected at higher levels at 5 days after hatching (dah) in both ovaries and testes compared with other stages, supporting the previously reported requirement of Ago-mediated pathways to clear the maternal mRNAs during the early embryogenesis. The Piwis were abundantly expressed in tilapia testes, indicating their essential roles in male germline, especially in spermatogenesis. Notable expression of Piwis was also detected in skeletal muscle, indicating that piRNA pathway may not only be confined to development and maintenance of the germline but may also play important roles in somatic tissues. The expression of Piwil1 and Piwil2 was examined by quantitative PCR (qPCR) and in situ hybridization (ISH) to validate the spatial and temporal expression profiles. Taken together, these results present a thorough overview of tilapia Argonaute family and provide a new perspective on the evolution and function of this family in teleosts. |

Attention Score in Context
This research output has an Altmetric Attention Score of 5. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 27 October 2022.
All research outputs
#6,803,988
of 24,690,130 outputs
Outputs from Development Genes and Evolution
#122
of 505 outputs
Outputs of similar age
#110,171
of 375,163 outputs
Outputs of similar age from Development Genes and Evolution
#2
of 9 outputs
Altmetric has tracked 24,690,130 research outputs across all sources so far. This one has received more attention than most of these and is in the 72nd percentile.
So far Altmetric has tracked 505 research outputs from this source. They receive a mean Attention Score of 4.4. This one has done well, scoring higher than 75% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 375,163 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
