Regulation of Bone Metabolism
Bone is formed through the processes of endochondral and intramembranous ossification. In endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (MSCs) differentiate directly into osteoblasts to form bone. The steps of osteogenic proliferation, differentiation,...

متن کاملCoordination of export and glycosylation of landomycins in Streptomyces cyanogenus S136.
In Streptomyces cyanogenus S136 gene cluster for biosynthesis of polyglycosylated angucycline landomycin A (LaA), a divergently oriented gene pair for a TetR-family regulator (lanK) and an efflux protein (lanJ) is located, whose functions remained obscure. Overexpression and disruption studies showed that lanK and lanJ genes control LaA resistance. Also, a constitutive lanK overexpression led t...
متن کاملRegulation of trehalose metabolism by Streptomyces griseus spores.
Spores of Streptomyces griseus contain trehalose and trehalase, but trehalose is not readily hydrolyzed until spore germination is initiated. Trehalase in crude extracts of spores, germinated spores, and mycelia of S. griseus had a pH optimum of approximately 6.2, had a Km value for trehalose of approximately 11 mM, and was most active in buffers having ionic strengths of 50 to 200 mM. Inhibito...
متن کاملThe metabolism of hypoxanthine desoxyriboside in animal tissues.
Klein (1) has made a detailed investigation of the action of “purine nucleosidase” on the various purine desoxyribosides. He found that preparations of animal tissues which split purine ribosides also split the purine desoxyribosides, yielding the purine base and a reducing sugar. The enzyme preparations were inactivated upon dialysis, but could be reactivated by the addition of arsenate or pho...
