R, overexpression of the other RCAN1 construct (RCAN1Tg1) under the exact same Nse-Cre driver did not have an effect on EPM open-arm time, (Mann?Whitney U(18) 0.140, p 0.9; Fig. 4F ). Also, postdevelopmental RCAN1 overexpression beneath CamkII -Cre did not affect EPM open-arm time (CamkII -RCAN1Tg1a open-arm time, Mann hitney U(70) 0.018, p 0.9; CamkII RCAN1Tg1 open-arm time, Mann hitney U(28) 0.873, p 0.4; Fig. 4F ).

Rcan1 KO mice show decreased measures of anxiousness inside the EPM. A, Rcan1 KO mice devote significantly additional time exploring the open arms on the EPM compared with their WT littermates.4,6-Dichloro-2-(ethoxymethyl)pyrimidine custom synthesis N ten KO, 12 WT.2-Bromo-4-chloro-5-methoxypyridine web B, Rcan1 KO mice enter the open arms early inside the EPM test (minute 1) whereas their WT littermates improved open-arm exploration starting at the third minute of testing compared with minute 1. N ten KO, 9 WT. C, Total distance moved and speed of Rcan1 KO mice are indistinguishable from WT mice inside the EPM. N ten KO, 12 WT. D, Rcan1 KO mice display similar PPI of acoustic startle responses compared with their WT littermates. E, Western blot analysis of RCAN1 expression within the PFC of RCAN1 transgenic (Tg) mice made use of for this study. Upper blot is stained with an RCAN1 antibody that recognizes endogenously expressed RCAN1.1L ( 38 kDa) and RCAN1.four ( 28 kDa) protein isoforms and transgenically expressed FLAG-tagged human RCAN1.PMID:24257686 1S protein ( 30 kDa; for extra particulars, see Oh et al., 2005; Hoeffer et al., 2007). Reduce blot is stained having a FLAG antibody, confirming expression of transgene. Nse-Cre driver line, CamkII -Cre (T-29) driver line. GAPDH, loading manage. Image is representative of 3 independent blots. WT represents the WT handle for each breeding cross. F, Mice overexpressing human RCAN1 early in development (Nse-RCAN1Tg1a) show decreased EPM open-arm time compared with WT littermates. No difference in open-arm time was observed driving an alternative RCAN1 construct (RCAN1Tg1) using the very same Nse-Cre driver. No distinction in open-arm time was also observed with postdevelopmental RCAN1 overexpression (CamkII -Cre) of either RCAN1 construct.
