Description
Hexose-6-phosphate dehydrogenase (H6PD)is the initial component of a pentose phosphate pathway inside the endoplasmic reticulum (ER) that generates NADPH for ER enzymes. In liver, H6PD is required for the 11-oxoreductase activity of 11ss-hydroxysteroid dehydrogenase type 1 (11ss-HSD1), which converts inactive 11-oxo glucocorticoids to their active 11-hydroxyl counterparts; consequently, H6PD null mice are relatively insensitive to glucocorticoids, exhibiting fasting hypoglycemia, increased insulin sensitivity despite elevated circulating levels of corticosterone, and increased basal and insulin-stimulated glucose uptake in muscles normally enriched in Type II (fast) fibers which have increased glycogen content. They also display a progressive vacuolar myopathy evident after 4 weeks of age.

Description
Very little is known about how intervertebral disc (IVD) is formed or maintained. Members of the TGF- superfamily are secreted signaling proteins that regulate many aspects of development including cellular differentiation. We recently showed that deletion of Tgfbr2 in Col2a expressing tissue results in alterations in development of IVD annulus fibrosus. The results suggested TGF- has an important role in regulating development of the axial skeleton, however, the mechanistic basis of TGF- action in these specialized joints is not known. To understand the mechanism of TGF- action in IVD development, we undertook a global analysis of gene expression comparing gene expression profiles in sclerotome cultures treated with TGF- or BMP4. As expected, treatment with BMP4 resulted in up-regulation of cartilage marker genes including Acan, Sox 5, Sox6, and Sox9. In contrast, treatment with TGF-1 did not regulate expression of cartilage markers but instead resulted in up-regulation of many IVD markers including Fmod and Adamtsl2. We propose TGF- has two functions in IVD development: 1) to prevent chondrocyte differentiation in the presumptive IVD and 2) to promote differentiation of annulus fibrosus from sclerotome. We have identified genes that are enriched in the IVD and regulated by TGF- that warrant further investigation as regulators of IVD development.

Description
By carrying out a systematic structure/function study of the RANK cytoplasmic domain, we previously identified a specific 4-a.a. RANK motif (IVVY535-538) which plays a critical role in osteoclastogenesis by mediating commitment of macrophages to the osteoclast lineage. We have recently validated the role of this IVVY motif in osteoclastogenesis in vivo by generating knockin (KI) mice bearing inactivating mutations in the RANK IVVY motif. This microarray experiment was performed to determine whether the IVVY motif is involved in regulating gene expression in osteoclastogenesis.

Description
Global energy balance in mammals is controlled by the actions of circulating hormones that coordinate fuel production and utilization in metabolically active tissues. Bone-derived osteocalcin, in its undercarboxylated, hormonal form, regulates fat deposition and is a potent insulin secretagogue. Here, we show that insulin receptor (IR) signaling in osteoblasts controls osteoblast development and osteocalcin expression by suppressing the Runx2 inhibitor Twist-2. Mice lacking IR in osteoblasts have low circulating undercarboxylated osteocalcin and reduced bone acquisition due to decreased bone formation and deficient numbers of osteoblasts. With age, these mice develop marked peripheral adiposity and hyperglycemia accompanied by severe glucose intolerance and insulin resistance. The metabolic abnormalities in these mice are improved by infusion of exogenous under-carboxylated osteocalcin. These results indicate the existence of a bone-pancreas endocrine loop through which insulin signaling in the osteoblast ensures osteoblast differentiation and stimulates osteocalcin production, which in turn regulates insulin sensitivity and pancreatic insulin secretion to control glucose homeostasis.
