Quantification of canonical transient receptor potential (TRPC) channels expression in tibialis anterior (TA), extensor digitorum longus (EDL), and soleus (Sol) muscles from TRPC1+/+ and TRPC1−/− mice. A: TRPC1+/+ mice. Each cDNA was amplified in duplicate, and threshold cycle (Ct) values were averaged for each duplicate. The average Ct value for cyclophilin D was subtracted from the average Ct value for the gene of interest, giving ΔCt (n = 5 or 6). Note that gene expression is inversely proportional to ΔCt. B: TRPC1−/− mice. ΔCt values were obtained from TRPC1−/− samples (n = 4–6). ND, not detected.
