Objective: One research group has recently published three articles on the ways in which alcohol companies and industry social aspects organizations (SAOs) communicate with public. These show how information produced by works to produce doubt uncertainty. Replies from SAOs were respective scientific journals. This article examines these “moments of controversy,” asking what ways, grounds, do co...

Thyroid hormones play important roles in bone growth, development, and turnover. To exert its biological activity, T(4) needs to be converted to T(3) by iodothyronine deiodinase. In human thyroid gland as well as rat brown adipose tissue, type 2 iodothyronine deiodinase (D2) expression is regulated by a TSH receptor-cAMP-mediated mechanism. TSH receptor knockout mice demonstrated the direct eff...

Osteocare, a herbal formulation, has been found to be very effective in bone mineralization and support of the microstructure of bone tissue. The water-soluble components of Osteocare (WSCO) induced osteogenic activity in human osteoblast-like SaOS-2 cells. The addition of WSCO (100 μg/ml) to SaOS-2 cells was effective in increasing the cell proliferation by 41.49% and DNA content by 1.9-fold. ...

OBJECTIVE NUF2 (NUF2, Ndc80 kinetochore complex component), which is essential for kinetochore-microtubule attachment in mitosis, has emerged as a critical mediator of the cell cycle in multiple tumour occurrences. In the present study, we aimed to investigate the role of NUF2 in osteosarcoma, one of the most common primary bone tumours in children and young adults. MATERIALS AND METHODS Lent...

UNLABELLED Devitalized Saos-2, cultured human osteosarcoma cells, or guanidinium-hydrochloride (GuHCl) extracts of these cells, induce ectopic bone and marrow formation when implanted subcutaneously in Nu/Nu mice. The aim of the present study was to characterize the bone marrow induced by Saos-2 cell extracts, specifically to determine which of the four major hematopoietic cell lineages: erythr...

the aim of this study was to evaluate and compare the cytotoxicity induced by two resin-based sealers, 2seal and ah plus, in two osteoblast-like cell lines, mg-63 and saos-2. using sterile discs of both sealers in complete media, 24- and 72-h extracts were prepared. the extracts were exchanged with saos-2 or mg-63 cell culture media at 75% confluence, and after 24 h incubation, cell viability t...

The insulin growth factor-I receptor (IGF1R) signaling is a key mechanism for osteosarcoma (OS) cell proliferation. GSK1904529A is a novel small molecule IGF1R kinase inhibitor. Its activity against OS cells was tested. In both established OS cell lines (Saos-2 and MG-63) and primary human OS cells, treatment with GSK1904529A (at nM concentrations) significantly inhibited cell proliferation. At...

The quaternary benzo[c]phenanthridine alkaloid sanguinarine inhibits the proliferation of cancerous cells from different origins, including lung, breast, pancreatic and colon, but nothing is known of its effects on osteosarcoma, a primary malignant bone tumour. We have found that sanguinarine alters the morphology and reduces the viability of MG-63 and SaOS-2 human osteosarcoma cell lines in co...
