OBJECTIVES Aortic valve (AV) calcification occurs via a pathophysiological process that includes lipoprotein deposition, inflammation, and osteoblastic differentiation of valvular interstitial cells. Here, we investigated the association between endoplasmic reticulum (ER) stress and AV calcification. APPROACH AND RESULTS We identified ER stress activation in AV of patients with calcified AV s...
UNLABELLED Unloading can prevent bone formation by osteoblasts. To study this mechanism, we focused on a ubiquitin ligase, Cbl-b, which was highly expressed in osteoblastic cells during denervation. Our results suggest that Cbl-b may mediate denervation-induced osteopenia by inhibiting IGF-I signaling in osteoblasts. INTRODUCTION Unloading, such as denervation (sciatic neurectomy) and spacefl...
Title:Acute murine antigen-induced arthritis is not affected by disruption of osteoblastic glucocorticoid signalling
With rising incidence of breast carcinoma in Asian population, staging workup remains a crucial entity diseasemanagement and outcome. Bone scintigraphy for detection osteoblastic metastasis has remained convenient choice.However, the presence underlying lytic bony lesions sensitivity 99mTc-MDP bone scan is questionable when comparedto 18F-FDG PET-CT scan. We present case that showed better pick...
BACKGROUND The skeleton is the most common site of colonization by metastatic cancers. Zoledronic acid (ZA) has been shown to be effective for the treatment of bone metastases regardless of whether the bone lesions are osteolytic or osteoblastic. Biochemical markers of bone turnover may be useful tools to quantify the degree of bone remodeling in the presence of bone metastases. The aim of this...
BACKGROUND Bony metastases were occasionally the initial presentations of malignancy. Overlooking of bony changes on radiographs in cancer patients with non-specific clinical symptoms may lead to delayed diagnosis. CASE PRESENTATION We presented a 70-year-old male having hypercalcemia and diffuse osteoblastic bone metastases on routine plain films. Finally, prostate cancer was diagnosed with ...
NELL1 is a secretory osteogenic protein containing several structural motifs that suggest that it functions as an extracellular matrix component. To determine the mechanisms underlying NELL1-induced osteoblast differentiation, we examined the cell-adhesive activity of NELL1 using a series of recombinant NELL1 proteins. We demonstrated that NELL1 promoted osteoblastic cell adhesion through at le...
Tolerance of intravenous indomethacin treatment for premature infants with patent ductus arteriosus.
stable or partial response, suggesting that, in addition to causing sclerosis of bone, APD may have an antitumour effect. Factors released from tumours stimulate osteoblastic activity3 and osteolysis mediated by osteoclasts.4 APD is a potent inhibitor of osteoclast function, and such inhibition combined with the osteoblastic factors produced by tumour cells may explain the bony sclerosis seen i...
