Myogenic response (and effects of 30 μm Ni2+) in young WT (A), young CaV3.2KO (B), mature adult WT (C) and mature adult CaV3.2KO (D) mouse mesenteric artery. Myogenic tone (MT, %) in young WT vs. CaV3.2KO mice (E, same mice as in A and B), and mature adult WT vs. CaV3.2KO mice (F, same mice as in C and D). Effects of paxilline on MT in young WT (G) vs. CaV3.2KO mice (H). *
