Our transgenic neuronal p60TRP bioluminescence mouse model allows in vivo analysis in living animals.
Our transgenic p60TRP mice allow in vivo analysis in living mice to study memory & learning effects, as well as higher brain cognitive functions
Neuron-specific over-expression of p60TRP & luciferase in the mouse brain allows us to investigate in vivo in living mice the effect of p60TRP on brain development and cognitive functions in a spatial and temporal dependent manner.
P60TRP improves cognitive functions in mice. Results obtained from twoday RAWM testing in p60TRP transgenic mice as described in supplemental ‘Materials and methods’. Data were collected from three-months-old p60TRP transgenic mice and wild-type littermates. Each block consists of four trials. Average error committed by p60TRP transgenic mice for each trial block. The data shown were obtained from female p60TRP transgenic mouse line-1 (S1 38) (diamond, n 8) and wild-type littermates (squares, n 8) (A). Average error of male mice for each trial block. The data shown were obtained from p60TRP transgenic mouse line-1 (S1) (diamond, n 10) and wildtype littermates (squares, n 10) (B). Average error of male and female mice for each trial block. The data shown were obtained from p60TRP transgenic mouse line-1 (S1) (diamond, n 12) and wildtype littermates (squares, n 12) (C). Average error of male and female mice for each trial block. The data shown were obtained from the p60TRP transgenic mouse line-2 (S2 31) (diamond, n 12) and wild-type littermates (squares, n 12). The data shown in A-F were collected independently on separate days with new mice each time. Data are presented as the mean SD (by ANOVA) (*P 0.05 compared with controls) (D)–(F).
as well as general systems biology studies:
Neuronal over-expression of p60TRP affects various cardiac protein functions. Red color: activation of Nnt-, Txnl1/Rab5-, Ang/MasR/Rab5/Col6a3-signaling pathways; green color: inhibition of Ckb/m-, Atp5- and Ak1-signaling pathways; which in turn modulate pivotal cardiac myocytes’ K+ channels’ activities and cardiac output.
