Induction and Survival of Diploid Gynogenesis With Ultraviolet Light‐Irradiated Sperm in the Manila Clam Ruditapes philippinarum

open access: yesAquaculture Research, Volume 2024, Issue 1, 2024.
In order to produce gynogenetic diploid of Manila clam, Ruditapes philippinarum, we studied the optimal conditions of gynogenetic diploid induced by ultraviolet (UV). The irradiance of UV‐induced sperm was 230 μW (cm2·s), and the irradiation time was 0, 3, 6, 9, 12, 15, 18, 21, 24, and 27 s.

A Study of Dual Function and Expression Pattern of Klf4 between Two Different Processes of Differentiation and Maintenance of Pluripotency in Spermatogonial Stem Cells

open access: yesAndrologia, Volume 2024, Issue 1, 2024.
Krüppel‐like factor 4 (Klf4) is a transcription factor involved in proliferation, self‐renewal, differentiation, apoptosis, and somatic cell reprogramming; thus, it has a critical role in accurate spermatogenesis. In this study, we examine the different protein localizations of Klf4 in the mouse testis and in two populations of spermatogonial stem ...

Identification of a cathepsin D potentially involved in H2A cleavage from scallop Chlamys farreri

open access: yes, 2010
We report here a cDNA and its deduced amino acid sequence encoding a cathepsin D-like, aspartic protease from Chlamys farreri (denoted as CfCD) by expressed sequence tag and rapid amplification of cDNA ends techniques. The cDNA of CfCD consisted of 1,810

DataSheet1_Identification and characterization of gonadotropin-releasing hormone (GnRH) in Zhikong scallop Chlamys farreri during gonadal development.docx

open access: yes, 2023
Gonadotropin-releasing hormone (GnRH) controls synthesis of sex steroid hormones through hypothalamic-pituitary-gonadal (HPG) axis in vertebrates. But in mollusks, research on neuroendocrine control of gonadal function, such as the function of GnRH ...

Molecular characterization of a defender against apoptotic cell death 1 gene (CfDAD1) from the mollusk Chlamys farreri

open access: yesInvertebrate Survival Journal, 2018
The defender against apoptotic cell death 1 (DAD1) was a negative regulator to inhibit the apoptosis process. In the present study, a DAD1 gene (designated as CfDAD1) was identified in Zhikong scallop Chlamys farreri.

The first identification of a malectin gene (CfMal) in scallop Chlamys farreri: sequence features and expression profiles

open access: yesInvertebrate Survival Journal, 2019
Malectin is a newly discovered lectin of the endoplasmic reticulum (ER) that might be involved in innate immunity. Information about the roles of malectin in innate immunity is scarce.

The Caspase Homologues in Scallop Chlamys farreri and Their Expression Responses to Toxic Dinoflagellates Exposure

open access: yes, 2022
The cysteine aspartic acid-specific protease (caspase) family is distributed across vertebrates and invertebrates, and its members are involved in apoptosis and response to cellular stress.
