The T(X;Y)V7 rearrangement in Drosophila has originally been recognized as a Shaker-like mutant because of its behavioral and electrophysiological phenotype. The gene whose expression is altered by the V7 rearrangement has been characterized. It encodes a novel Ca(2+)-binding protein named frequenin, which is related to recoverin and visinin. In vitro, the(More)
The four known members of the KCND/Kv4 channel family encode voltage-gated potassium channels. Recent studies provide evidence that members of the Kv4 channel family are responsible for native, rapidly inactivating (A-type) currents described in heart (I(TO)) and neurons (I(SA)). In this study, we cloned the human KCND1 cDNA, localized the KCND1 gene to(More)
The development of the adult central nervous system of Drosophila requires a precise and reproducible pattern of neuroblast proliferation during postembryonic neurogenesis. We show here that mutations in the minibrain (mnb) gene cause an abnormal spacing of neuroblasts in the outer proliferation center (opc) of larval brain, with the implication that mnb(More)
A human cDNA for the voltage-sensitive potassium channel subunit Kv4.2 has been cloned and functionally characterized. The human Kv4.2 (KCND2) gene was mapped at 7q31-32. Kv4.2 mRNA is prominently expressed in human brain. Relatively high concentrations of Kv4.2 mRNA occurred in mRNA preparations of amygdala, caudate nucleus, cerebellum, hippocampus,(More)
We have cloned and functionally expressed Kv6.2, a new member of the Kv6 subfamily of voltage-gated potassium channel subunits. The human Kv6.2 (KCNF2) gene was mapped at 18q22-18q23. Kv6.2 mRNA is preferentially expressed in rat and human myocard. Rat and human Kv6.2 subunits appear to be unable to form functional Kv channels in a heterologous expression(More)
Caspase 8 is a key apoptotic factor in the receptor/ligand apoptosis-signaling cascade. Absent caspase 8 expression is shown to correlate with poor prognosis in neuroblastoma. Paradoxically, the caspase 8 gene can produce as plice variant and novel inhibitor of itself-caspase 8l. The presence of caspase 8 alone in tumors may not necessarily portend a good(More)
Endothelial cells (ECs) are directly exposed to hypoxia and contribute to injury during myocardial ischemia/reperfusion. Hypoxic preconditioning (HPC) protects ECs against hypoxia injury. This study aimed to explore whether HPC attenuates hypoxia/reoxygenation (H/R) injury by suppressing excessive endoplasmic reticulum stress (ERS) in cultured microvascular(More)
