Genetic effects of melatonin receptor genes on chicken reproductive traits
MTNR1A MTNR1B MTNR1C polymorphism egg production traits
2015/6/24
The melatonin receptors are G protein-coupled receptors (GPCR) that bind melatonin. Three types of melatonin receptors have been cloned. The MTNR1A (or Mel1A or MT1) and MTNR1B (or Mel1B or MT2) recep...
Polymorphism, Genetic Effect and Association with Egg Production Traits of Chicken Matrix Metalloproteinases 9 Promoter
Chicken Matrix Metalloproteinases 9 Ovary Polymorphism Reproduction
2016/5/17
Matrix metalloproteinases (MMP) are key enzymes involved in cell and tissue remodeling during ovarian follicle development and ovulation. The control of MMP9 transcription in ovarian follicles occurs ...

Mapping of Quantitative Trait Loci Affecting Growth Traits in a Japanese Native Chicken Cross
Chicken Hinai-dori Breed Quantitative Trait Loci Body Weight Average Daily Gain
2016/5/9
The Hinai-dori is a breed of chicken native to Akita Prefecture, Japan. An F2 resource population produced by crossing low- and high-growth lines of the Hinai-dori breed was analyzed to detect quantit...
Motility of Japanese Quail (Coturnix japonica) Sperm Diluted with Chicken Seminal Fluid
chicken seminal fluid quail sperm motility
2009/7/31
This study examined whether chicken seminal fluid was a useful diluent for quail sperm. Both sperm motility and progressive motility, when diluted with chicken seminal fluid (90.4% and 54.6%), were si...
Culture of Chicken Granulosa Cells from Small Yellow Follicles:A Suitable Culture System
chicken granulosa cells culture system
2009/7/31
In the chicken ovary, one small yellow follicle (SYF) is selected daily to enter the hierarchy and ovulates a few days later. Cellular changes that occur in these follicles may provide an understandin...
Serum-free Culture of Chicken Bursal Epithelial Cells
bursa of Fabricius epithelial cell serum-free culture
2009/7/31
We developed a method of culturing bursal epithelial cells under serum-free condition. Bursal cells sampled from 14 days of embryogenesis were cultured in DMEM/Ham’s F12 1 : 1 mixture medium supplemen...
