Taxifolin glycoside is a new drug candidate for the treatment of atopic dermatitis (AD). Many drugs cause side effects such as long QT syndrome by blocking the human ether-a-go-go related gene (hERG) K(+) channels. To determine whether taxifolin glycoside would block hERG K(+) channels, we recorded hERG K(+) currents using a whole-cell patch clamp(More)
Nitric oxide (NO) is produced by nitric oxide synthase (NOS) in dermal fibroblasts and is important during wound healing. Intermediate conductance Ca²⁺-activated K+ (IK; IK1; KCa3.1; IKCa; SK4; KCNN4) channels contribute to NOS upregulation, NO production, and various NO-mediated essential functions in many kinds of cells. To determine if the action of NO(More)
The aim of the present study was to investigate whether hirsutenone affects the human ether-a-go-go related gene (hERG) K(+) channels. Many drugs promote formation of the acquired form of long QT syndrome (LQTS) by blocking the hERG K(+) channels. Hirsutenone, a new candidate for the treatment inflammatory skin lesions, induced a concentration-dependent(More)
Euglycemia is the ultimate goal in diabetes care to prevent complications. However, the benefits of euglycemia in type 2 diabetes are controversial because near-euglycemic subjects show higher mortality than moderately hyperglycemic subjects. We previously reported that euglycemic-diabetic rats on calorie-control lose a critical liver weight (LW) compared(More)
Human cardiac fibroblasts (HCFs) have various voltage-dependent K(+) channels (VDKCs) that can induce apoptosis. Hydrogen peroxide (H2O2) modulates VDKCs and induces oxidative stress, which is the main contributor to cardiac injury and cardiac remodeling. We investigated whether H2O2 could modulate VDKCs in HCFs and induce cell injury through this process.(More)
This study surveys the improvement characteristics in old-aged muscular mitochondria by bio-active materials coated fabric (BMCF). To observe the effects, the fabric (10 and 30%) was worn to old-aged rat then the oxygen consumption efficiency and copy numbers of mitochondria, and mRNA expression of apoptosis- and mitophagy-related genes were verified.
