The use of non-human animals in experiments or behavorial observations. The research is conducted inside universities, medical schools, pharmaceutical companies, farms, defence establishments, and commercial facilities that provide animal-testing services to industry. It includes pure research such as genetics, developmental biology, behavioral studies, as well as applied research such as pharmaceutical testing in pre-clinical, before human, studies.
NSE-p25 mice were created by pronuclear injection of an NSE-p25 transgene, produced internally at Pfizer, with transplantation of embryos to pseudopregnant CD-1 females. At weaning genomic DNA was isolated from tail tissue and founder transgenics were identified by PCR that specifically amplified DNA sequences from the human p25 cDNA. Founder mice were bred to FVB/N mates and transgenic offspring were used to maintain the tra…

The Prkdc gene encodes the catalytic subunit of a nuclear DNA-dependent serine/threonine protein kinase (DNA-PK). DNA-PK is required for the non-homologous end joining (NHEJ) pathway of DNA repair, which rejoins double-strand breaks. It is also required for V(D)J recombination, a process that utilizes NHEJ to promote immune system diversity. Mature B and T cells are critical components for an adaptive immune system. DNA-PK kn…

T-box transcription factor (TBX21) is a member of the T-box protein family, which shares a common DNA-binding domain. TBX21 plays a critical role in Th1 cell differentiation through stimulation of IFN γ. Due to a hypersensitive immune system, the Tbx21 (-/-) rat model is useful for studies of acute and chronic human asthma, Crohn’s disease, colitis, cancer metastasis, autoimmune disorders and inflammation.Tbx21 (T-beta) Knock…
