DNA uptake in the post-acrosomal region of the spermatozoa takes place exclusively in immotile spermatozoa that are naturally unable to fertilize eggs. The present study aimed to assess whether passive transmission of non-viral vectors to the surrounding areas of chicken embryos could be an alternate mechanism in chicken sperm-mediated gene transfer. First, the presence of nucleases in rooster ...
The creatine kinase (CK) isoenzyme system is essential for motility in rooster and sea urchin sperm. In the present study, biochemical characterization as well as immunofluorescence and confocal laser microscopy with highly specific antibodies against various chicken CK isoenzymes revealed that cytosolic brain-type CK isoenzyme (B-CK) is the only CK isoenzyme in rooster seminal plasma, while th...
Background: Low uptake of exogenous DNA by sperm and reduced number of fertilized oocyte by transfected sperm are the major obstacles for progression of sperm mediated gene transfer. Therefore, the modification of sperm mediated gene transfer procedure needs to be required. The purpose of this study was to evaluate the efficiency of FuGene 6 compare to lipofection in transfection medium for int...
Composition and thermotropic phase behavior of sperm membrane lipids from species ranging in sensitivity to cold shock were determined. Lipids from whole sperm and sperm plasma membrane were fractionated into neutral lipid, glycolipid, and phospholipid fractions. Compositional analyses were completed for free sterols, phospholipids and phospholipid-bound fatty acids. Phase transition temperatur...
Chicken seminal plasma contains a high content of sex steroids including progesterone (P4). According to a published study, in vitro supplementation of P4 to the semen resulted in decreased fertility in the White Leghorn chicken; however, it is not known if increased P4 production in vivo is associated with decreased sperm fertility. Therefore, the aim of the present experiment was to study the...
Conservation of genetic resources by semen cryopreservation is essential for biodiversity conservation and storage rare poultry breeds. Despite the widespread use this method not all individuals presentia similar capacity to be used after defrosting. The aim current study was identify SNP markers linked candidate genes potentially associated with rooster (Gallus gallus) sperm motility cryoprese...
Improving the Quality of Rooster Sperm during Storage at 4 °C by adding Quercetin in form nano-Liposomes and NLC a Diluting Medium
The Effect of using Different Levels Luteolin on Reducing Malondialdehyde Content and Increasing the Motility Viability Ross 308 Rooster Sperm during Cryopreservation Thawing Process
Semen cryopreservation is necessary for banking germplasm from critical poultry stocks. To date, glycerol is the most effective cryoprotectant for poultry sperm; however, the contraceptive effects of glycerol require a significant reduction of the cryoprotectant from thawed semen before artificial insemination (AI). The effectiveness of glycerol reduction by dialysis, Percoll density gradient c...
