lysosomal storage diseases/potassium

Promoting lysosomal trafficking represents a promising therapeutic approach for lysosome storage diseases. Efficient Ca(2+) mobilization from lysosomes is important for lysosomal trafficking. Ca(2+) release from lysosomes could generate a negative potential in the lumen to disturb subsequent Ca(2+)

Efficient lysosomal Ca2+ release plays an essential role in lysosomal trafficking. We have recently shown that lysosomal big conductance Ca2+-activated potassium (BK) channel forms a physical and functional coupling with the lysosomal Ca2+ release channel Transient Receptor Potential Mucolipin-1

When administered to humans and animals, the iodine-containing drug amiodarone can cause pulmonary toxicity. As part of the pulmonary response to amiodarone, the drug and its principal metabolite, desethylamiodarone, accumulate in alveolar macrophages. Little is known about the susceptibility of

OBJECTIVE The lysosome is a membrane-enclosed organelle widely found in every eukaryotic cell. It has been deemed as the stomach of the cells. Recent studies revealed that it also functions as an intracellular calcium store and is a platform for nutrient-dependent signal transduction. Similar with

A dataset of 237 human Ether-à-go-go Related Gene (hERG) potassium channel inhibitors (180 of which were used for model building and validation, whereas 57 constituted the "true" external prediction set) collected from 22 literature sources was modeled by 3D-SDAR. To produce reliable and

Bedaquiline was approved by USFDA in 2012 for pulmonary MDR-TB. The IC₅₀ value of bedaquiline was reported to be remarkably low (25 nM), effectively inhibiting mycobacterial ATP synthase. In addition to these obvious assets of bedaquiline, the potential disadvantages of bedaquiline

Infantile cystinosis is a metabolic lysosomal storage disease of cystine affecting most of the body cells. The first symptoms appear after 5-6 months of life: anorexia, vomiting, polyuria, polydipsia and failure to thrive, associated with the signs of tubular Fanconi syndrome including glycosuria,

Human-ether-a-go-go-related channel (hERG) is a voltage gated potassium channel (Kv11.1) abundantly expressed in heart and brain tissues. In addition to playing an important role in mediation of repolarizing K+ currents (IKr) in Action Potential (AP), hERG is notorious for its propensity to interact

Neuronal ceroid lipofuscinosis (NCL) is a genetically heterogeneous group of lysosomal diseases that collectively compose the most common Mendelian form of childhood-onset neurodegeneration. It is estimated that ∼8% of individuals diagnosed with NCL by conservative clinical and histopathologic
