VASA is one of the important regulatory factors that determine the development of the reproductive system. However, no information on vasa gene from Pleocyemata Brachyura is available. By using Race, we obtained a full-length cDNA of Sp-vasa of the green mud crab Scylla paramamosain. The full-length (2,851 bp) cDNA of vasa encodes a peptide of 631 amino acids. Real-time PCR results indicated that the expression level of Sp-vasa in the growth stage of ovary was higher than in the maturation… 

Erk2 in ovarian development of green mud crab Scylla paramamosain.

Positive signals illustrated that Sp-erk2 mRNA is present in follicular cells when the ovary is in early stages, and in both follicular Cells and oocytes when it is in mature phases, which suggest that Sp -erk2 is important for ovarian development.

The vasa gene encodes a DEAD-box ATP-dependent RNA helicase that regulates the translation of multiple mRNAs involved in germ line differentiation. This protein has been deeply studied in many

Identification and Sexually Dimorphic Expression of a FoxL2-like Gene in Mud Crab (Scylla paramamosain): Potential Roles in Male Differentiation and Development

The results imply that the SpFoxl2 may play an important role in male differentiation and development, laying a foundation for future research on sexual differentiation of the Scylla paramamosain species.

Transcriptome analysis of the differences in gene expression between testis and ovary in green mud crab (Scylla paramamosain)

This is the first large-scale RNA sequencing of S. paramamosain and identified many important functional genes and made a preliminary attempt to construct the regulatory network involved in the gonadal development of crustaceans.

A model for germ cell development in a fully segmented worm

It is hypothesized that primordial germ cells are supplied from the pygidium to every newly-generating segment which later settle in the parapodium, which will explain how polychaetes can generate gametes in each body segment, even those that are independently separated with a complete septum.

The Regulatory Mechanism of Sexual Development in Decapod Crustaceans

This study summarizes the available information in the field, highlights gaps, and lays the foundations for further studies and a better understanding of the regulatory mechanism of sexual development in decapods.

Cloning and characterization of a vasa-like gene in Apostichopus japonicus and its expression in tissues

It was deduced primarily that the Aj-vasa may be a useful maker for investigating the germline origin and differentiation in sea cucumber A. japonicus based on amino acid sequences of VASA, indicating that its function may be realized by space reactions among different motifs.

Hormonal Regulation of Vasa-Like Messenger RNA Expression in the Ovary of the Marine Teleost Sparus aurata

Abstract The vasa gene is an important maternal regulator of primordial germ cell (PGC) development in both vertebrate and invertebrate models. It is also expressed in the mature gonads, but its role

Differential expression of two vasa/PL10-related genes during gametogenesis in the special model system Rana

The identification of two DEAD-box vasa/PL10 orthologues (RlVlg and RlPL10) in a species complex of the genus Rana characterized by hybridogenetic reproduction, an enigmatic process that involves the exclusion of an individual genome, and endoreduplication events is reported.

Characterization of a vasa‐like gene from the pacific white shrimp Litopenaeus vannamei and its expression during oogenesis

It is demonstrated that the vasa homolog from L. vannamei is a gonad specific germline cell marker that could be exploited to enhance the understanding of developmental and reproductive processes in the germline of this economically important shrimp.

Progress in Studies of vasa Gene

The structure, function, expression pattern and the application of the vasa gene as a molecular marker of primordial germ cells are reviewed, and the perspective ofvasa gene studies is also introduced.

The construction of normalized cDNA library and preliminary EST analysis from the gonad development and sexual differentiation related organs of Scylla serrata

To study the molecular mechanism in gonad development and sexual differentiation of Scylla serrata,a normalized cDNA library was constructed using the combination of SMART(Switch mechanisms at the

Differential expression of vasa RNA and protein during spermatogenesis and oogenesis in the gibel carp (Carassius auratus gibelio), a bisexually and gynogenetically reproducing vertebrate

Interestingly, the αVasa in combination with a nuclear dye can differentiate critical stages of spermatogenesis and oogenesis in fish, and is a useful tool to identify fish germ cell development and differentiation.

In vivo RNA interference in oyster –vasa silencing inhibits germ cell development

Oyvlg appears to be essential for germ cell development in Crassostrea’gigas, particularly for mitotic proliferation and early meiosis, and is demonstrated for the first time that in’vivo RNA interference works efficiently in a bivalve species.
