EGF and colorectal carcinoma: In addition to EGF signaling, EGFR has been reported to be involved in theglucose transport by associating and stabilizing the active glucose transporter,SGLT1 [13],[20].Since the expression of EGFR was reduced by HDACi in CRC cells, the levels ofSGLT1 expression and intracellular glucose in response to HDACi were alsoexamined.
