Cx50 (connexin50), a member of the α-family of gap junction proteins expressed in the lens of the eye, has been shown to be essential for normal lens development. In the present study, we identified a CaMBD [CaM (calmodulin)-binding domain] (residues 141-166) in the intracellular loop of Cx50. Elevations in intracellular Ca2+ concentration effected a 95%(More)
This paper presents a case-study of work done by Applied Language Solutions (ALS) for a large social networking provider who claim to have built the world's first multi-language social network, where Internet users from all over the world can communicate in languages that are available in the system. In an initial phase, the social networking provider(More)
The therapeutic potential of Wnt proteins has long been recognized but challenges associated with in vivo stability and delivery have hindered their development as drug candidates. By exploiting the hydrophobic nature of the protein we provide evidence that exogenous Wnt3a can be delivered in vivo if it is associated with a lipid vesicle. Recombinant Wnt3a(More)
Content localisation via machine translation (MT) is a sine qua non, especially for international online business. While most applications utilise rule-based solutions due to the lack of suitable in-domain parallel corpora for statistical MT (SMT) training, in this paper we investigate the possibility of applying SMT where huge amounts of monolingual(More)
Glutamate transporters, also referred to as excitatory amino acid transporters (EAATs), are membrane proteins that regulate glutamatergic signal transmission by clearing excess glutamate after its release at synapses. A structure-based understanding of their molecular mechanisms of function has been elusive until the recent determination of the x-ray(More)
Gamma-aminobutyric acid (GABA) transporter subtype 1 (GAT1), which transports extracellular GABA into presynaptic neurons, plays an important regulatory role in the function of GABAergic systems. However, the contributions of the GAT1 in regulating mental status are not fully understood. In this paper, we observed the behavioral alterations of GAT1 knockout(More)
Neuronal and glial glutamate transporters limit the action of excitatory amino acids after their release during synaptic transmission. Recent structural and functional investigations have revealed much about the transport and conducting mechanisms of members of the sodium-coupled symporter family responsible for glutamate clearance in the nervous system. In(More)
We have shown previously that the Ca2+-dependent inhibition of lens epithelial cell-to-cell communication is mediated in part by the direct association of calmodulin (CaM) with connexin43 (Cx43), the major connexin in these cells. We now show that elevation of [Ca2+](i) in HeLa cells transfected with the lens fiber cell gap junction protein sheep Cx44 also(More)
There is increasing evidence that GABAergic system plays an important role in the neural control of learning and memory processes. GAT1 over-expressing mice (NA) were generated, in which GAT1 is under the control of a neuron-specific enolase (NSE) promoter, to investigate effects of GABA transporter on cognitive function. Our results revealed that NA mice(More)
Ion channels are involved in normal physiologic processes and in the pathology of various diseases. In this study, we investigated the presence and potential function of transient receptor potential melastatin 7 (TRPM7) channels in the growth and proliferation of FaDu and SCC25 cells, two common human head and neck squamous carcinoma cell lines, using a(More)
