WebCircadian control of gene expression is achieved by two transcriptional activators, Clock and Bmal1, which stimulate cryptochrome (Cry1 and Cry2) and Period (Per1, Per2 and Per3) repressors that feed back on Clock-Bmal1 activity. Here we show that Creb activity during fasting is modulated by Cry1 and Cry2, which are rhythmically expressed in ... WebCompared with the healthy mucosa from CRC patients, expression levels of PER1, PER2, PER3, and CRY2 in their tumor tissue are much lower, while TIM level was much enhanced. There was no significant difference in the CRY1 expression level. High levels of TIM mRNA were much prevalent in the tumor mucosa with proximal lymph nodes.
