PURPOSE Identification of new targeted therapies is critical to improving the survival rate of patients with osteosarcoma. The goal of this study is to identify kinase based potential therapeutic target in osteosarcomas. EXPERIMENTAL DESIGN We used a lentiviral-based shRNA kinase library to screen for kinases which play a role in osteosarcoma cell survival. The cell proliferation assay was us...

A spontaneously occurring subcutaneous mass in the left forelimb of a nine-year-old rabbit (Oryctolagus cuniculus) was examined histopathologically and immunohistochemically. Clinically, edema and hemorrhage were seen around the mass. No connection of the tumor mass to the appendicular skeleton was found. The tumor was arranged in a solid growth pattern and irregular bundles, and neoplastic cel...

Recent evidence has shown that miR-409-3p was down-regulated in several types of cancer, including osteosarcoma. However, the potential role of miR-409-3p in osteosarcoma remains largely unknown. In the present study, we showed that overexpression of miR-409-3p in osteosarcoma cells inhibited cell proliferation in vitro and suppressed tumor growth in vivo, and the restoration of miR-409-3p prom...

OBJECTIVE The purpose of the present study was to determine whether type III IFN can modulate the autophagic response in human osteosarcoma cell. METHODS Human osteosarcoma cell were treated with Interferon-λ1. We investigated that Interferon-λ1 could inhibit the invasive ability of osteosarcoma cells by Matrigel invasion assay. Autophagy were assessed by acridine orange staining, MDC stainin...

SRCIN1 (SRC kinase signalling inhibitor 1) is a new tumor suppressor gene. Previous studies showed that SRCIN1 played a tumor suppressor role in the development of lung cancer and breast cancer. However, the role of SRCIN1 in osteosarcoma is still unknown. In this study, we demonstrated that SRCIN1 was downregulated in osteosarcoma cell lines compared with osteoblastic cell line. Moreover, SRCI...

So far, the role of Ether à go-go 1 (Eag1) potassium channels in migration and invasion progression of cancers remains elusive. In the present study, the effects of Eag1 knockdown on osteosarcoma cell proliferation, growth, and apoptosis were examined. Then, we evaluated the effects of Eag1 silencing on osteosarcoma cell migration and invasion. In addition, we detected the expression of vascula...

calcifying odontogenic cyst (coc), central odontogenic fibroma (cof) and aggressive central giant cell granuloma (cgcg) are rare pathologic diseases affecting the jaws. while the co-existence of two of them is reported in the literature, existence of all three conditions in one patient is an extremely rare entity. in the present report, initial biopsy revealed fibrosarcoma, therefore mandibular...

Carboxypeptidase E (CPE), a prohormone processing enzyme, has been implicated in the progression of multiple malignancies. However, the biological role and molecular mechanisms of CPE in osteosarcoma remain elusive. In this study, we assessed the effects of CPE on cell proliferation, tumorigenicity, migration, and invasion in osteosarcoma. Our results showed that silencing of CPE significantly ...
