“…Owing to the high proportion of pseudo-males in the C. semilaevis population and the necessity for sex control, it is of great significance to distinguish pseudo-males from males and females. To address this, the C. semilaevis genome laid a solid basis for understanding sex-determination mechanisms and developing sex identification methods 1 , 8 . On one hand, numerous genes related to sex determination and/or differentiation have been found, including DMRT1 1 , 9 , 10 , Dazl 11 – 13 , piwil2 14 , Figla 15 , GATA4 16 , aqp1aa 17 , and β-catenin1 18 .…”

Fish sex identification is a basic technique of great importance for both fish genetic studies and fisheries. Due to the sexual reversal phenomenon in many fish species, a simple and rapid molecular identification method for fish genetic sex is urgently needed to suit versatile detection scenarios, such as point-of-need applications. In this study, we took Cynoglossus semilaevis as an example, established a recombinase-aided amplification (RAA)-based method for sex identification, and combined the RAA-detection with two result visualization approaches with distinct features, capillary electrophoresis (CE) and lateral flow dipstick (LFD). Specific primers and probe were designed to specifically detect the sex chromosome W of C. semilaevis in order to distinguish the genetic sex between males, pseudo-males and females. To evaluate the performance of our methods, the genetic sex for twenty-eight males, sixty-eight pseudo-males and fifty-four females were examined with the RAA-based method and classical PCR-based genotyping method, demonstrating the consistent results of sex identification between both methods. The RAA-LFD method is operationally simple, rapid (~ 30 min) and holds great potential for point-of-need applications of fish sex identification, including fishery fields. The method presented here could be effective for identifying fish gender with the ZW karyotype.

“…It was reported that Rb 1 attenuated ␤ AP 25-35 -induced tau protein hyperphosphorylation in cortical neurons, showed a possibility of inhibiting amyloid fibril formation by A␤. The research progress of ginsenoside Rg 1 , involved in the pharmacology of central nervous system, cardiovascular system, endocrine system, and immune system, revealed that Rg1 has the effect on Parkinson's disease and Alzheimer's disease, which were associated to A ␤ aggregation process [24].…”

“…The sex chromosomes are often not differentiated morphologically and often resist identification by chromosome staining techniques. In such cases, the sex chromosome system needs to be inferred from sex-reversal or other genomic manipulations [Ward, 2002;Zhang et al, 2009].…”

Sex determination and differentiation are key events in the development of either the testis or ovary in fish. Sex determination mechanisms include environmental and genetic regulation. Research on sex determination systems and their related genes have been implemented in the teleost species, but the amount of information about these genes in cartilaginous fish is very scarce. This paper summarizes the few available data on molecular studies and chromosome localization of specific sequences useful to discriminate between various chromosome pairs in the common torpedo, Torpedo torpedo, and in the scyliorhinid coral catshark, Atelomycterus marmoratus, species that do not have morphologically distinct sex chromosomes. In addition, recent results obtained by sequence analysis of foxl2, a female-specific gene expressed during early phases of gonadal development in interesting key-species, such as the holocephalian Callorhinchus milii, is discussed. Nevertheless, the mechanism of sex determination in cartilaginous fish remains largely unknown. Further research needs to be carried out regarding the importance of basic and applied sex determination studies in fish, including chromosomal distribution of sex-related sequences.
