In this work we studied the physiological role of HOTAIR during the process of mineralization using osteoblastic osteosarcoma cells focusing in ALPL (Tissue Non-Specific Alkaline Phosphatase), a pivotal gene that controls bone formation.

Furthermore, we validated the highly differential expression of six genes including angiopoietin 1, IGFBP3, ferredoxin 1, BMP, decorin, and fibulin 1 in osteoblastic osteosarcoma relative to non-osteoblastic osteosarcoma.
We, therefore, investigated whether intrinsic IGFBPs interfere with IGF I-induced regulation of IGF 1R expression and with the biological response to IGF I in two human tumor cell lines, the non-small-cell lung cancer cell line A549 and the osteoblastic osteosarcoma cell line Saos-2/B-10.
Since estrogen is important in preventing osteoporosis in postmenopausal women and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is an estrogen antagonist in reproductive tissues, we investigated the effects of 17beta-estradiol (E2) and TCDD on collagenase-3 secretion using parathyroid hormone (PTH)-stimulated UMR 106-01 cells, a rat osteoblastic osteosarcoma cell line.
Dual fluoroimmunohistochemical staining of estrogen receptor (ER) and bromodeoxyuridine was performed in a human osteoblastic osteosarcoma cell line, HOS TE85 cells.
1,25-Dihydroxyvitamin D3 (1,25(OH)2D3) significantly stimulated cellular alkaline phosphatase activity in a human osteoblastic osteosarcoma cell line (TE-85 cells) in serum-free medium with 0.1% bovine serum albumin as the hormone carrier in a dose- and a time-dependent manner.
