From: Expression of circadian clock gene human Period2 (hPer2) in human colorectal carcinoma
Determination of hPer2 mRNA by real-time PCR. ΔCt (N): Ct value of GAPDH was subtracted from Ct value of hPer2 of non-cancerous tissues. ΔCt (T): Ct value of GAPDH was subtracted from Ct value of hPer2 of CRC. Bar value(ΔCt (N)- ΔCt (T))represents the difference of hPer2 mRNA between non-cancerous tissue and paired CRC tissue. Each bar represented for one sample. Bar value = -1 indicates that hPer2 mRNA of CRC is 2-1-fold of that of paired non-cancerous tissue. Bar value = 1 indicates that hPer2 mRNA of CRC is 21-fold of that of paired non-cancerous tissue. Bar value≤-1 indicates that the expression of hPer2 is decreased in tumors. Bar value≥ 1 indicates that the expression of hPer2 is increased in tumors.
