Sestrin 2 is a conserved antioxidant protein that is involved in p53‑dependent antioxidant defenses and protects cells against oxidative stresses. The present study was conducted to examine the expression of sestrin 2 in colorectal cancer (CRC) and investigate a possible relationship between sestrin 2 expression and prognosis in CRC. The expression of(More)
Calcium/calmodulin-dependent serine protein kinase (CASK), which localizes at cell–cell adhesion sites and binds to the heparan sulfate proteoglycan syndecan-2, is involved in cell proliferation, cytoskeletal remodeling, and cell migration. To demonstrate the role of CASK in colorectal cancer (CRC) carcinogenesis, we examined the expression of CASK and its(More)
The interaction of hesperidin (HES) or icariin (ICA) and lysozyme (LYS) was studied by fluorescence spectroscopy in physiological buffer solution. It was observed that there was a strong fluorescence quenching effect of hesperidin or icariin on lysozyme. The quenching constants of the drugs with lysozyme were measured at different temperatures, and the(More)
Sestrin 2 is a conserved antioxidant protein that reduces reactive oxygen species (ROS) and inhibits mammalian target of rapamycin complex 1 (mTORC1). We previously showed that sestrin 2 is abnormally decreased in colorectal cancer (CRC). To elucidate the molecular mechanism behind the potential contribution of sestrin 2 to CRC, we used a lentiviral(More)
