Background: Cholesterol loaded cyclodextrin (CLC) efficiently protected sperm from some species. On the other hand vitrification of sperm especially in human opened a new horizon in the field of sperm freezing. The aim of the present study was to evaluate CLC on vitrification of cat sperm. Materials and Methods: Tom epididymal sperm (n=9) was extracted from epididymides and subjected to vitrifi...

objective(s): the purpose of this study was to investigate the role of chloride channel protein 2 (clc-2) in glutamate-induced apoptosis in the retinal ganglion cell line (rgc-5). materials and methods: rgc-5 cells were treated with 1 mm glutamate for 24 hr. the expression of clc-2, bax, and bcl-2 was detected by western blot analysis. cell survival and apoptosis were measured by 3-(4,5-dimethy...

ClC-7 Cl(-) channels expressed in osteoclasts are important for bone resorption since it has been shown that disruption of the ClCN7 gene in mice leads to severe osteopetrosis. We have previously reported that Cl(-) currents recorded from mouse osteoclasts resemble those of ClC-3 Cl(-) channels. The aim of the present study was to determine the expression of ClC-3 channels in mouse osteoclasts ...

CLC channels and transporters are expressed in most tissues and fulfill diverse functions. There are four human CLC channels, ClC-1, ClC-2, ClC-Ka, and ClC-Kb, and five CLC transporters, ClC-3 through -7. Some of the CLC channels additionally associate with accessory subunits. Whereas barttin is mandatory for the functional expression of ClC-K, GlialCam is a facultative subunit of ClC-2 which m...

Inactivation of the mainly endosomal 2Cl(-)/H(+)-exchanger ClC-5 severely impairs endocytosis in renal proximal tubules and underlies the human kidney stone disorder Dent's disease. In heterologous expression systems, interaction of the E3 ubiquitin ligases WWP2 and Nedd4-2 with a "PY-motif" in the cytoplasmic C terminus of ClC-5 stimulates its internalization from the plasma membrane and may i...

We demonstrated a switchable reflective lens based on choleteric liquid crystal (CLC) with a plano-convex shape. The plano-convex CLC lens was fabricated by assembling a planar substrate and a concave substrate. The reflective CLC lens exhibits wavelength selectivity and handedness sensitivity like the conventional CLC cell. The plano-convex CLC lens acts as a biconvex lens with the same curvat...

The skeletal muscle chloride channel CLC-1 and the ubiquitous volume-activated chloride channel CLC-2 belong to a large gene family whose members often show overlapping expression patterns. CLC-1 and CLC-2 are coexpressed in skeletal and smooth muscle and in the heart. By coexpressing CLC-1 and CLC-2 in Xenopus oocytes, we now show the formation of novel CLC-1/CLC-2 heterooligomers that yield t...
