Repression of cyclin D1 as a target for germ cell tumors
metastatic germ cell tumors cyclin D1
2014/12/12
Metastatic germ cell tumors (GCT) are curable, however GCTs refractory to cisplatin-based chemotherapy have a poor prognosis. This study explores D-type cyclins as molecular targets in GCTs because al...
Expression Patterns of Germ Cell-specific Phosducin-like 2 during Testicular and Ovarian Development in Chickens
Chickens In situ Hybridization Pdcl2 qRT-PCR
2016/5/5
Phosducin (PDC) is a photoreceptor cell-specific protein that is phosphorylated by cyclic nucleotide-dependent protein kinase. PDC and PDC-like proteins (PDCL, PDCL2, and PDCL3) are members of a conse...
Assessment of Piwil2 Gene Expression Pattern upon Germ Cell Development from Mouse Embryonic Stem Cell
Embryonic stem cell Germ cell Embryoid body Piwil2
2015/9/18
Background: In order to improve culture conditions for optimal spermatogenesis, quantitative assessment of the male germ cell gene expression profile upon spontaneous ES cell differentiation is necess...
An Attempt at Fusing Primordial Germ Cell with Embryonic Blood Cell in Chickens Using Inactivated Sendai Virus or Electrical Stimulation
cell fusion electrical stimulation embryonic blood cell HVJ primordial germ cell
2009/7/31
In order to produce nuclear transferred PGCs, fusion of primordial germ cell (PGC) with embryonic blood cell (EBC) was attempted. PGCs and EBCs were isolated from the blood of stages 13-15 embryos. Th...
Preparation of Functional Ecdysteroid Receptor Proteins（EcR and USP）Using a Wheat Germ Cell-Free Protein Synthesis System

2009/3/6
Ecdysone receptor (EcR) and ultraspiracle (USP) of the lepidopteran Chilo suppressalis were expressed using a wheat germ cell-free protein synthesis system, and the functions of the expressed protei...
Germ cell degeneration in the contralateral testis of the guinea pig with unilateral torsion of the spermatic cord. Quantitative and ultrastructural studies
testis torsion quantitation germ cell guinea pig reproduction
2009/2/23
This study evaluated the long term effects of unilateral torsion of the spermatic cord on the contralateral testis of guinea pigs, employing both fine structural and quantitative studies. Young, adu...
Pure Sertoli Cell Cultures：A New Model for the Study of Somatic-Germ Cell Interactions

2009/2/19
A new technique involving a brief hypotonic treatment was developed for obtaining pure rat Sertoli cell cultures. This method for the selective removal of the germ cells present in Sertoli cell enri...
Reproductive aging in the Brown Norway rat is characterized by accelerated germ cell apoptosis and is not altered by luteinizing hormone replacement
Brown Norway rat accelerated germ cell apoptosis luteinizing hormone replacement
2009/2/18
Reproductive aging in the male Brown Norway (BN) rat is characterized by decreased Leydig cell steroidogenesis associated with seminiferous tubule dysfunction. This could be a result of a combination ...
Contrin, the human homologue of a germ-cell Y-box-binding protein：cloning, expression, and chromosomal localization
human homologue germ-cell Y-box-binding protein chromosomal localization
2009/2/18
Inactivation of germ-cell-specific molecules essential for the production of functional spermatozoa could lead to attractive new means for male contraception. The mouse protein MSY2 is the mammali...
Hormonal regulation of spermatogenesis in the hypophysectomized rat: quantitation of germ-cell population and effect of elimination of residual testosterone after long-term hypophysectomy
Testis germ cells androgen morphometry
2009/2/17
Spermatogenesis continues after long-term hypophysectomy (Hx), but massive cell degeneration prevents seminiferous tubules from attaining the full complement of cells. One objective of this study ...
Interactions of proteases and protease inhibitors in Sertoli-germ cell cocultures preceding the formation of specialized Sertoli-germ cell junctions in vitro
proteases and protease inhibitors Sertoli-germ cell specialized Sertoli-germ cell
2009/2/17
The biochemical mechanism(s) by which germ cells can form specialized junctions with Sertoli cells in the seminiferous epithelium at various stages of the spermatogenic cycle is unknown. This stud...
Is Leydig cell steroidogenic function affected by the germ cell content of the seminiferous tubules?
Leydig cell steroidogenesis
2009/2/17
The effect of testicular germ cell content on Leydig cell steroidogenic function in vivo in adult rats was examined. Three experimental paradigms were used to effect germ cell changes. First, a vita...
