PURPOSE Osteosarcoma is the most common primary malignancy of bone. The long-term survival of osteosarcoma patients hinges on our ability to prevent and/or treat recurrent and metastatic lesions. Here, we investigated the activation of peroxisome proliferator-activated receptor gamma (PPARgamma) and retinoid receptors as a means of differentiation therapy for human osteosarcoma. EXPERIMENTAL ...
CD151, a tetraspanin family protein involved in cell-cell and cell-extracellular matrix interaction, is differentially expressed in osteosarcoma cell membranes. Thus, this study aimed to investigate the role of CD151 in osteosarcoma metastasis. We analyzed CD151 expression in patient tissue samples using immunohistochemistry. CD151 expression was also silenced with shRNA in osteosarcoma cells o...
Small cell osteosarcoma may present a challenging primary diagnosis on cytologic assessment owing to its rarity and its morphologic similarity to other small round blue cell tumors. Five cases of small cell osteosarcoma from our cytopathology archives were identified and reviewed and cytologic features elaborated. Three cases were fine-needle aspirations from bony lesions in the classic locatio...
<p class="abstract">Osteosarcoma is the most common primary malignant bone tumor. Jaw an uncommon site. The etiopathogenesis still unknown. We present a case of 47-year-old female who underwent left partial maxillectomy as lesion increased in size over one month after removal tooth. Prior to surgery, computed tomography (CT) scan was suggestive maxillary sinus carcinoma and biopsy report ...
AIM To demonstrate the capability of the invertible micellar polymer nanoassemblies (IMAs) to deliver and release curcumin using the recently discovered mechanism of macromolecular inversion to treat bone tumor cells. MATERIALS & METHODS The effect of IMA-mediated delivery of curcumin on osteosarcoma cell survival was investigated using MTS assays. To assess the effect of IMAs-delivered curcu...
Osteosarcoma is the most common primary bone tumour in children and adolescents. Accumulating evidence has shown that microRNAs (miRNAs) participate in the development of almost all types of cancer. Here, we investigated the role of miR-224 in the development and progression of osteosarcoma. We demonstrated that miR-224 was down-regulated in osteosarcoma cell lines and tissues. Lower miR-224 le...
The Hedgehog-GLI signaling pathway is active in a variety of human malignancies and is known to contribute to the growth and survival of human osteosarcoma cells. In this study, we examined the expression and regulation of GLI transcription factors in multiple canine osteosarcoma cell lines and analyzed the effects of inhibiting GLI with GANT61, a GLI-specific inhibitor. Compared with normal ca...
MicroRNA-26b inhibits osteosarcoma cell migration and invasion by down-regulating PFKFB3 expression.
MicroRNAs regulate target gene expression and are involved in cell proliferation, apoptosis, differentiation, tumor invasion, and cancer stem cell regulation, among other processes. MicroRNA-26b (miR-26b) is closely related to tumor occurrence and development. In this study, we analyzed miR-26b expression in osteosarcoma tissue, its effect on Saos-2 osteosarcoma cell proliferation and invasion,...
Abstract Osteosarcoma is the most common primary malignant bone tumor; main treatment method surgery and adjuvant chemotherapy, with a 5-year survival rate of less than 20% for metastatic patients. Schisandrin B abundant active ingredient found in fruit Schisandra chinensis (Turcz.) Baill., Schisandraceae, which has document properties such as liver protection, antioxidant, anti-inflammatory, a...
Osteosarcoma is the most common malignant bone tumor in adolescents. The function of basic leucine zipper and W2 domains 2 (BZW2) in tumor progression has been reported. However, the role and mechanisms of BZW2 in osteosarcoma remain to be determined. The aim of the present study was to reveal the expression and biological functions of BZW2 in osteosarcoma and to elucidate the proximal mechanis...
