Mutations in the MYOC gene may lead to juvenile open-angle glaucoma with high intraocular pressure, and are detected in about 4% of people with adult onset glaucoma. Most of these mutations are found in the third exon of the gene encoding the olfactomedin-like domain located at the C terminus of the protein. Another olfactomedin-related protein, known as(More)
MicroRNAs (miRNAs) are short non-coding RNAs that interfere with translation of specific target mRNAs and thereby regulate diverse biological processes. Recent studies have suggested that miRNAs might have a role in osteoblast differentiation and bone formation. Here, we show that miR-542-3p, a well-characterized tumor suppressor whose downregulation is(More)
Th17 cells produce IL-17, and the latter promotes bone loss in collagen-induced arthritis in mice. Blocking IL-17 action in mouse model of rheumatoid arthritis reduces disease symptoms. These observations suggest that Th17 cells may be involved in the pathogenesis of bone loss. However, the role of Th17 cell in estrogen (E2) deficiency-induced bone loss is(More)
Withania somnifera or Ashwagandha is a medicinal herb of Ayurveda. Though the extract and purified molecules, withanolides, from this plant have been shown to have different pharmacological activities, their effect on bone formation has not been studied. Here, we show that one of the withanolide, withaferin A (WFA) acts as a proteasomal inhibitor (PI) and(More)
Medicarpin, a pterocarpan class of naturally occurring benzopyran furanobenzene compound was synthesized in gram scale to investigate its effects on murine bone cells and in ovariectomized (OVx) mice. Medicarpin, at as low as 10(-10)M suppressed osteoclastogenesis in bone marrow cells (BMCs). Medicarpin-induced apoptosis of mature osteoclasts isolated from(More)
PURPOSE To characterize properties of Pdlim2, a novel PDZ and LIM domain-containing protein. METHODS cDNA encoding Pdlim2 was identified in a cDNA library of transcripts expressed in the tissues of the rat eye irido-corneal angle. The expression pattern of the Pdlim2 gene was studied by Northern blot analysis and in situ hybridization. Proteins(More)
The effects of standardized and concentrated extract of Ginkgo biloba, Egb 761, were studied on estrogen deficiency-induced bone loss in ovariectomized (OVx) rats rendered osteopenic. Upon osteopenia development, Egb 761 was administered at a dose of 100mgkg(?1)day(?1) by oral gavage to OVx rats whereas control group received vehicle. Following 5 weeks of(More)
Kaempferol (K), a flavonol, is known to have anti-osteoclastogenic effect. We here show that K, from 0.2 to 5.0 microM, increased mineralized nodules in rat primary osteoblasts. K also significantly attenuated adipocyte formation from bone marrow cells (BMCs). A single oral dose of 1 mg/kg body weight of K in Sprague-Dawley (180-200 g) rats resulted in a(More)
Plants synthesize secondary metabolites, including flavonoids, which play important role during various stresses for their survival. These metabolites are also considered as health-protective components in functional foods. Flavonols, one of the important groups of flavonoids, apart from performing several roles in plants have been recognized as potent(More)
Recently, we reported that extract of Dalbergia sissoo made from leaves and pods have antiresorptive and bone-forming effects. The positive skeletal effect attributed because of active molecules present in the extract of Dalbergia sissoo. Caviunin 7-O-[β-D-apiofuranosyl-(1-6)-β-D-glucopyranoside] (CAFG), a novel isoflavonoid show higher percentage present(More)
