Sperm-mediated gene transfer was used to produce transgenic rabbits that expressed the porcine growth hormone gene under the control of a metallothionein promoter. The gene that encodes the selectable marker green fluorescent protein (GFP) was inserted downstream of the transgene. After lipofectin-mediated gene transfer into sperm cells and after subsequent(More)
The ability of rabbit spermatozoa to bind exogenous DNA during sperm-mediated gene transfer (SMGT) was tested in our study. Fresh collected semen, or fully capacitated sperm cells, was co-cultured with plasmid DNA labeled with tetramethyrodamine-6-dUTP. Fluorescent spermatozoa were counted before and after DNaseI treatment. Results showed that(More)
Discoidin domain receptor 1 (DDR1) is a tyrosine kinase collagen adhesion receptor that mediates cell migration through association with non-muscle myosin IIA (NMIIA). Because DDR1 is implicated in cancer fibrosis, we hypothesized that DDR1 interacts with NMIIA to enable collagen compaction by traction forces. Mechanical splinting of rat dermal wounds(More)
To study the position and immunogenicity of rSP10, the rabbit rsp10 gene which did not include sequences coding for signal peptides was inserted into expression vector pET30a. An in-frame fusion protein was made such that a His6 stretch was produced at the N terminus of re-rSP10. High expression was obtained, the amount of re-rSP10 up to 67% in the total(More)
The pUC19-OMT plasmids were cut by Ssp 1 and the products in 900 bp were recovered from low-melting agarose gel and used as probes which were labeled by Digoxigenin. After being denatured, the probes were dropped on the chromosome samples which were also denatured to anneal with them. The anti-digoxigenin antibodies labeled with colloidal gold were used to(More)
Bovine sperm heads were separated via ultrasonic treatment and centrifugation. Anti-bull sperm IgG was produced by immunizing rabbits with acrosome-reacted bull sperm heads. SDS PAGE patterns revealed that the main membrane proteins on acrosome-reacted bull sperm head were sp18 family, including 18, 16, and 14 kD, which represented about 64% of the total(More)
