(Submitter supplied) Osteosarcomas are the most common primary malignant tumors of bone, showing complex chromosomal rearrangements with multiple gains and losses. A frequent deletion within the chromosomal region 3q13.31 has been identified by us and others, and is mainly reported to be present in osteosarcomas. We have previously proposed the gene limbic-system associated membrane protein (LSAMP) as the target for the deletion. more...

(Submitter supplied) in 25% - 30% of all OS cases the chromosome region 17p11.2-p12 is aberrant. Using SNP array in conjunction with expression microarrays we try to identify genes which can be classified as oncogens or are in someway benificial to the survival of the tumor.

(Submitter supplied) The WWOX gene is a tumor suppressor probably involved in regulation of cell cycle and apoptosis and downregulated in variety of cancer types.However, its role in colon cancerogenesis is unknown. The aim of this study was to characterize how WWOX may be involved in colon cancerogenesis or cancer progression, how it influences the basic cancer cell features and modifies cell expression profile.Our observations suggest that in HT29 colon cancer cell line increased expression of WWOX may result in transition of cancer cells into more normal- like colon epithelium phenotype, on the other hand in SW480 WWOX revealed the well-known tumour suppressor properties. more...

(Submitter supplied) Osteosarcomas are the most common primary malignant tumours of bone, and almost all conventional osteosarcomas are high-grade tumours showing complex genomic aberrations. We have integrated genome-wide genetic and epigenetic profiles from the EuroBoNeT panel of 19 human osteosarcoma cell lines based on microarray technologies. The cell lines showed complex patterns of DNA copy number changes, where copy number gains were significantly associated with gene-rich regions of the genome and losses with gene-poor areas. more...

(Submitter supplied) Purpose: The overall survival rate for metastatic osteosarcoma hovers around 20%. Responses to second-line chemotherapy, targeted therapies, and immunotherapies have demonstrated limited efficacy in metastatic osteosarcoma. Our objective is to validate differentially expressed genes and signaling pathways between non-metastatic and metastatic osteosarcoma, employing single-cell RNA sequencing (scRNA-Seq) and additional functional investigations. more...

(Submitter supplied) The WWOX gene is known for its tumor suppressor character and seems to be one of the main cellular regulators of cell cycle and apoptosis. The aim of the study was to identify cellular pathways and biological processes influenced by WWOX in glioblastoma cells. Our experiment showed that in this type of cancer WWOX, beside cell cycle and apoptosis control, may be involved in metabolism, cytoskeleton structure and differentiation.

(Submitter supplied) Background Identification of the molecular determinants of invasion and metastatic potential may guide the development of a rational strategy for devising specific therapies that target the pathways leading to osteosarcoma. Methods In this study, we used pathway-focused GEarrays to screen for candidate genes related to tumor progression. Expression patterns of the selected genes were validated by real time PCR on 61 osteosarcoma patient tumor samples and correlated with clinical and pathological data. more...

(Submitter supplied) Osteosarcoma is a form of bone cancer that predominantly impacts osteoblasts, the cells responsible for creating fresh bone tissue. Typical indications include bone pain, inflammation, sensitivity, mobility constraints, and fractures. Utilizing imaging techniques such as X-rays, MRI scans, and CT scans can provide insights into the size and location of the tumor. Additionally, a biopsy is employed to confirm the diagnosis. more...

(Submitter supplied) To determine whether sarcomas – tumors of mesenchymal origin – are subject to the same technical artifacts, we profiled patient-derived tumor explants (PDXs) propagated from three aggressive subtypes: osteosarcoma, Ewing sarcoma (ES), desmoplastic small round cell tumor (DSRCT). Given the rarity of these sarcoma subtypes, we explored whether single-nuclei RNA-seq from more widely available archival frozen specimens could accurately be identified by gene expression signatures linked to tissue phenotype or pathognomonic fusion proteins.

(Submitter supplied) Osteosarcoma is the most common primary malignant bone tumor with a high risk of metastasis and recurrence. Metabolic reprogramming is a hallmark of osteosarcoma and other cancers and is associated with genetic and epigenetic alterations. RUNX2 is an important transcription factor for osteoblastic differentiation, and aberrant expression of the gene contributes to the development and progression of osteosarcoma. more...
