There is increasing evidence for the key role of osteocytes in the regulation of bone remodeling. One of the main products of these cells, sclerostin, inhibits bone formation and may also stimulate bone resorption. To our knowledge, there are few data in prostate cancer (PC) patients especially in patients with hypogonadism related to androgen deprivation therapy (ADT). The aim of this study was to compare serum levels of sclerostin in ADT-treated and untreated PC patients wit...

Modulation of c-Myb during chondrogenesis

Oralova Veronika , Buchtova Marcela , Janeckova Eva , Tucker Abigail , Matalova Eva

The c-Myb transcription factor is associated with proliferation of undifferentiated cells in number of tissues, but recent data suggests its role also in differentiation. c-Myb is important in formation of the cartilage, bone and apparently also in hard tissue mineralization (Matalova et al. 2011).Embryonic micromasses were established from mouse front limbs at the embryonic day E12. Micromass cultures represent an effective tool for experimenta...

Level of calcium intake modifies the correlation between parathyroid hormone and 25-hydroxyvitamin D: a proposal of adequate 25-hydroxyvitamin D levels in children

Reyes Maria Loreto , Molina Marcela , Escobar Raul , Hernandez Maria Isabel , Cavada Gabriel , Jr Camargo Carlos Arturo

Background: The ‘adequate’ level of 25-hydroxyvitamin D (25OHD) in children remains unclear. For bone outcomes, parathyroid hormone (PTH) is an important functional biomarker. Prior studies have shown too weak a correlation between 25OHD and PTH levels to determine adequate 25OHD level.Objective: To determine adequate 25OHD level(s) in children using a normal PTH value of 65 pg/ml while adjusting for calcium intake.Design...

Objectives: To elucidate the incidence and risk factors of skeletal toxicity in children with ALL treated with the dexamethasone-based DCOG-ALL9 protocol.Methods: Prospectively, the cumulative incidence of fractures was assessed in 672 patients and compared between different subgroups using the log-rank test. Serial measurements of bone mineral density of the lumbar spine (BMDLS) were performed in 399 ALL patients using dual energy X-ray absor...
