“…The binding complex moves to the circulatory system and regulates the release of insulin‐like growth factor (IGF) (Kelley et al, 2002). At the same time, single insulin binding domain proteins (EsSIBD), a potential member of the IGFBP family, is involved in the endocrine system and can promote the sex regulation process (Gai et al, 2010; Song, Liu, et al, 2018; Song, He, et al, 2018). Based on the changes of endogenous PcIAG after protein injection, we speculated that IAG, after secreted by an androgenic gland, is transmitted by three main paths including the ‘AG‐Mu’ axis, ‘AG‐VN‐Br’ axis and ‘AG‐TD‐Te’ axis.…”

“…The 10–16 nucleolus in oocytes of the IAG‐treated group was observed in this study, however, a previous study showed that there is 6–8 nucleolus in a nearly ripe vitellogenic state in P . clarkii (Song, Liu, et al, 2018; Song, He, et al, 2018). The injection of PcIAG recombinant protein might thus lead to the formation of yolk and the increase of the number of nucleoli.…”

“…In addition to these six conserved Cys residues, IAGs in some decapods were reported to contain additional Cys residues. For example, there existed two additional Cys residues respectively in A chain and B chain of the IAG in the Palaemonid species such as M. rosenbergii (Ventura et al 2009), Macrobrachium lar, Palaemon paucidens, Palaemon pacificus (Banzai et al 2012), M. nipponense (Ma et al 2013) and the Chinese mitten crab, Eriocheir sinensis (Song et al 2019), while there was only one additional Cys residue in the IAG of the Penaeid prawn Penaeus monodon (Mareddy et al 2011). The additional Cys residues may suggest the existence of the fourth disulphide bridges in IAGs, but it remains to be further verified.…”

A large number of decapod crustaceans with sexual dimorphism in body size, most of which, are important economic animals. Besides, some of them such as the red swamp crayfish Procambarus clarkii possess strong invasive ability and would damage ecosystem environment. Thereby, monosex culture of decapods would contribute to not only increasing yield and profits, but also reducing the risks of biological invasion. Insulin-like androgenic gland hormone was reported to be a key regulator in sex differentiation. All-male populations in Macrobrachium rosenbergii were successfully produced through insulin-like androgenic gland hormone manipulation. In addition to sex differentiation, insulin-like androgenic gland hormone was reported to be involved in male secondary sex characteristics maintenance, growth, metabolism, morphology change, ovary development and other functions. Considering its important application value for decapods, insulin-like androgenic gland hormone has attracted much attention in recent years. This hormone was reported to have the structure and function similar to androgenic gland hormone of isopods. In this study, the origin of name of androgenic gland hormone and insulin-like androgenic gland hormone was investigated, and the recent research on structure, function, application and molecular regulation mechanism of insulin-like androgenic gland hormone of decapods was reviewed.

“…Sex determination is an interesting theme, especially for researchers studying evolution and development. Accordingly, many studies have been conducted on sex-determining genes in several organisms, such as mammals [ 2 , 3 , 4 ], birds [ 5 , 6 , 7 ], insects [ 8 ], and crustaceans [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Primary sex determination depends on the sex chromosomes and is responsible for gonadal determination [ 16 ].…”

The brine shrimp Artemia has a ZW sex determination system with ZW chromosomes in females and ZZ chromosomes in males. Artemia has been considered a promising model organism for ZW sex-determining systems, but the genes involved in sex determination and differentiation of Artemia have not yet been identified. Here, we conducted transcriptome sequencing of female and male A. franciscana using PacBio Iso-Seq and Illumina RNA-Seq techniques to identify candidate sex determination genes. Among the 42,566 transcripts obtained from Iso-Seq, 23,514 were analyzed. Of these, 2065 (8.8%) were female specific, 2513 (10.7%) were male specific, and 18,936 (80.5%) were co-expressed in females and males. Based on GO enrichment analysis and expression values, we found 10 female-biased and 29 male-biased expressed genes, including DMRT1 and Sad genes showing male-biased expression. Our results showed that DMRT1 has three isoforms with five exons, while Sad has seven isoforms with 2–11 exons. The Sad gene is involved in ecdysteroid signaling related to molting and metamorphosis in arthropods. Further studies on ecdysteroid biosynthetic genes are needed to improve our understanding of Artemia sex determination. This study will provide a valuable resource for sex determination and differentiation studies on Artemia and other crustaceans with ZW systems.
