[Preparation and identification of recombinant adenoviruses carrying short hairpin RNA targeting parathyroid hormone related protein of goat].

Parathyroid hormone related protein (PTHrP) has important biological functions in calcium metabolism. The aim of this study was to silence the expression of PTHrP by RNA interference and recombinant adenovirus, and to provide a material to investigate the relative functions of PTHrP in goat mammary gland epithelial cell. The Block-iT shRNA interference system was used in this experiment.

[Preparation and application of goat deltafosB gene expression product antibody].

deltaFosB, a naturally occurring truncated isform of fosB gene, existed in many tissues stably and played an important role in formation and differentiation of adipocyte and osteoblast. deltaFosB may be related to the metabolism of calcium in bone and mammary gland and regulate the signal pathway of calcium transfer from bone to mammary gland. We first sub-cloned deltafosB gene of goat into the vector pET32a to construct prokaryotic expression vector pET32a-deltafosB.
