Cystatins - Extra- and Intracellular Cysteine Protease Inhibitors: High-level Secretion and Uptake of Cystatin C in Human Neuroblastoma Cells.

Cystatins are present in mammals, birds, fish, insects, plants, fungi and protozoa and constitute a large protein family, with most members sharing a cysteine protease inhibitory function. In humans 12 functional cystatins exist, forming three groups based on molecular organisation and distribution in the organism. The type 1 cystatins (A and B) are known as intracellular, type 2 cystatins (C, D,

Low-Level Cadmium Exposure Is Associated with Decreased Bone Mineral Density and Increased Risk of Incident Fractures in Elderly Men: The MrOS Sweden Study.

One risk factor for osteoporosis which has attracted increasing attention in recent years is exposure to cadmium. The aim of this study was to examine the associations between low-level cadmium exposure, from diet and smoking, and BMD and incident fractures in elderly men. The study population consisted of 936 men from the Swedish cohort of the MrOS study, aged 70-81 years at inclusion (year 2002-

Increased litter size and super-ovulation rate in congenic C57BL mice carrying a polymorphic fragment of NFR/N origin at the Fecq4 locus of chromosome 9.

By analysing N2 mice from a cross between the inbred C57BL strain B10.Q and the NMRI-related NFR/N strain, we recently identified a quantitative trait locus (QTL) influencing litter size. This locus is now denoted Fecq4, and it is present on the murine chromosome 9. In the present paper, we describe how the Fecq4 fragment originating form the NFR/N mouse strain will affect B10.Q mice by means of b

S-Nitrosylation of secreted recombinant human glypican-1.

Glypican-1 is a glycosylphosphatidylinositol anchored cell surface S-nitrosylated heparan sulfate proteoglycan that is processed by nitric oxide dependent degradation of its side chains. Cell surface-bound glypican-1 becomes internalized and recycles via endosomes, where the heparan sulphate chains undergo nitric oxide and copper dependent autocleavage at N-unsubstituted glucosamines, back to the

Deletion of the p53 tumor suppressor gene improves neuromotor function but does not attenuate regional neuronal cell loss following experimental brain trauma in mice.

Deletion of the tumor suppressor gene p53 has been shown to improve the outcome in experimental models of focal cerebral ischemia and kainate-induced seizures. To evaluate the potential role of p53 in traumatic brain injury, genetically modified mice lacking a functional p53 gene (p53(-/-), n = 9) and their wild-type littermates (p53(+/+), n = 9) were anesthetized and subjected to controlled corti
