Abstract
Mechanisms underlying sex determination and differentiation in animals are known to encompass a diverse array of molecular clues. Recent innovations in high-throughput sequencing and mass spectrometry technologies have been widely applied in non-model organisms without reference genomes. Crustaceans are no exception. They are particularly diverse among the Arthropoda and contain a wide variety of commercially important fishery species such as shrimps, lobsters and crabs (Order Decapoda), and keystone species of aquatic ecosystems such as water fleas (Order Branchiopoda). In terms of decapod sex determination and differentiation, previous approaches have attempted to elucidate their molecular components, to establish mono-sex breeding technology. Here, we overview reports describing the physiological functions of sex hormones regulating masculinization and feminization, and gene discovery by transcriptomics in decapod species. Moreover, this review summarizes the recent progresses of studies on the juvenile hormone-driven sex determination system of the branchiopod genus Daphnia, and then compares sex determination and endocrine systems between decapods and branchiopods. This review provides not only substantial insights for aquaculture research, but also the opportunity to re-organize the current and future trends of this field.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2016; 131:96-103.

Abstract
The effect of the herbicide atrazine was assayed in early juveniles of the redclaw crayfish Cherax quadricarinatus. Four cohorts of juveniles (a total of 280 animals) were exposed for 4 wk to each one of three atrazine concentrations (0.1, 0.5 and 2.5mg/L) or a control (0mg/L), from a commercial formulation having 90% of active principle. At the end of the exposure, no significant (p>0.05) differences in either mortality or molting were noted. However, the weight gain and the protein content of abdominal muscle decreased significantly (p<0.05) in the highest atrazine concentration as compared to control, indicating that atrazine acted as a relevant stressor, although at a concentration higher than those reported in the environment. Besides, the proportion of females increased progressively as the atrazine concentration increases, being significantly (p<0.05) higher than that of controls at the highest concentration assayed. Both macroscopic and histological analysis revealed a normal architecture of gonopores and gonads in both control and exposed animals. The obtained results strongly suggest that atrazine could be causing an endocrine disruption on the hormonal system responsible for the sexual differentiation of the studied species, increasing the proportion of female proportion without disturbing the gonad structure.

An insulin-like androgenic gland hormone gene in the mud crab, Scylla paramamosain, extensively expressed and involved in the processes of growth and female reproduction. Gen Comp Endocrinol 2014; 204:229-38. [PMID: 24929228 DOI: 10.1016/j.ygcen.2014.06.002] [Citation(s) in RCA: 65] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2014] [Revised: 05/30/2014] [Accepted: 06/01/2014] [Indexed: 10/25/2022]
Abstract
Insulin-like androgenic gland hormone (IAG) produced by androgenic gland (AG) in male crustaceans is regarded as a key regulator of sex differentiation. As a member of the insulin/insulin-like growth factor family, IAG is also likely involved in regulating somatic growth. In this study, a full-length cDNA of IAG (termed Sp-IAG) was isolated from the mud crab, Scylla paramamosain. Genomic DNA of Sp-IAG was also cloned, analysis of which reveals that Sp-IAG gene is organized in a 4 exon/3 intron manner. RNA in situ hybridization analysis detected positive signals in both type I and type II AG cells. Reverse transcription-polymerase chain reaction (RT-PCR) analysis showed that Sp-IAG was expressed not only in AG, but also in many other tissues. Sp-IAG expression levels in ovaries were examined at different stages of ovarian development (stages I to V); it was found that the expression was maintained at low levels during undeveloped stage (stage I) to late vitellogenic stage (stage IV) and then increased significantly at mature stage (stage V), suggesting that Sp-IAG may participate in inhibiting oocyte growth and vitellogenesis. The expression pattern of Sp-IAG during the molting cycle of the first stage crabs (C1) was also determined. Sp-IAG expression level continuously decreased from 0 h C1 (postmolt) crabs to 96 h C1 (premolt) crabs, and then increased significantly in the newly molted second stage crabs (C2, postmolt). The combined results suggested for the first time that IAG is involved in regulating ovarian development and somatic growth in crustaceans.

Abstract
BACKGROUND Lepidium meyenii is a plant, which has been used in folk medicine to treat infertility and to increase sexual desire. However, few reports have investigated the administration of this plant with other plants having the same properties. OBJECTIVE The present investigation was designed to evaluate whether the combination of Lepidium meyenii and Fagara tessmannii can improve spermatogenesis and testosterone level in rats. MATERIALS AND METHOD Twenty male rats were treated daily for 2 weeks with the hydroalcoholic extract of Fagara tessmannii and Lepidium meyenii (Fag + MN) as follow: (vehicle), (0.01 g + 0.5 mg), (0.1 g + 5 mg) and (1 g+ 50 mg)/kg BW. RESULTS At doses Fag 0.01 g/MN 0.5 mg and Fag 0.1 g/MN 5 mg, the weight of seminal vesicle, prostate, and testis significantly decreased (P < 0.05) while at dose Fag 1 g/MN 50 mg, the weight of epididymis and testis significantly increased (P < 0.05) when compared to the control. We noticed a significant increase of the number of spermatids/test (P < 0.05), epididymis sperm count (P < 0.05), and DSP/test of the rats at dose Fag 1 g/MN 50 mg while at dose Fag 0.01 g/MN 0.5 mg and Fag 0.1 g/MN 5 mg, sperm count was reduced in male organs, particularly in vas deferens (P < 0.05) and epididymis (P < 0.001). The serum testosterone concentration significantly decreased (P < 0.05) at lowest dose Fag 0.01 g/MN 0.5 mg. However, at highest dose Fag 1 g/MN 50 mg, the serum testosterone concentration increased significantly (P < 0.05). The length of stage VII-VIII and IX-I of the seminiferous tubule significantly (P < 0.05) increased while the length of stage II-VI significantly (P < 0.05) decreased. CONCLUSION The results indicated that the combination of Lepidium meyenii (Black Maca) with Fagara tessmannii can improve male reproductive organs activities.

Molecular characterization and expression analysis of an insulin-like gene from the androgenic gland of the oriental river prawn, Macrobrachium nipponense. Gen Comp Endocrinol 2013; 185:90-6.

Abstract
The androgenic gland (AG), a male-specific endocrine organ in crustacean, is responsible for the maintenance of male characteristics and gender differentiation. In this study, an AG-specific gene, the Macrobrachium nipponesne insulin-like androgenic gland factor (MnIAG) was isolated from a transcriptome library of M. nipponesne and its full-length cDNA sequences were obtained by RACE method. The cDNA was 1,547 bp in length and encoded a precursor protein of 175 amino acids. The deduced precursor protein consisted of a signal peptide, B chain, C peptide and an A chain, which exhibited the same structural organization as that of previously identified insulin-like androgenic gland in crustacean. The mature peptide of the MnIAG owned two additional conserved cysteine residues, which were also found in the Palaemonidae species reported. Results of the tissue distribution and in situ hybridization showed the MnIAG expressed exclusively in androgenic gland. The quantitative RT-PCR results demonstrated that the MnIAG transcript was present at blastula stage and later developmental stages with low levels, which suggested that the primordial cells of the AG might form at these stages.

Abstract
More and more evidence indicates that the insulin-like androgenic gland hormone (IAG) plays an important role in male sexual differentiation in crustaceans. In the present study, two IAG isoforms (Fc-IAG1 and Fc-IAG2) were identified from the penaeid shrimp Fenneropenaeus chinensis. Sequence analysis of IAG gene (Fc-IAG) showed that Fc-IAG1 and Fc-IAG2 were generated by alternative splicing of Fc-IAG pre-mRNA, and they shared almost the same deduced amino acid sequence. Both of them were composed of signal peptide, B chain, C peptide and A chain. They both contained the six conserved cysteine residues and a putative N-linked glycosylated site like IAGs reported in other crustacean species. Tissue distribution and in situ hybridization analysis revealed that they had the highest expression level in the androgenic gland. The transcripts of Fc-IAG1 and Fc-IAG2 could also be detected in hepatopancreas and nerve cord of both sexes at a low expression level. Analysis on their temporal expression profiles showed that they expressed at all embryonic and post-larvae stages. The expression of Fc-IAG1 at different developmental stages displayed a low and stable manner, while the expression of Fc-IAG2 began to increase from post-larvae stages, which suggested that Fc-IAG2 might be involved in male sexual differentiation. In the 5' flanking sequence of Fc-IAG, putative binding sites for transcription factors regulating transcription of hormone genes and genes related to sexual development were predicted, which provided us a primary understanding on the regulation mechanism of Fc-IAG gene. This is the first time to report the gene structure of IAG gene and distinct variants of IAG transcripts in crustaceans.
