Chondrosarcoma is the second most common bone malignancy in adults, and it is often resistant to traditional chemotherapy and radiation therapy. Permanent implantation of iodine-125 (125I) seeds has been explored for the treatment of many types of cancer. In this study, the aim was to investigate the proliferative and microRNA (miRNA) effects of 125I seeds irradiation on human chondrosarcoma SW1353 cells. First, a new in vitro 125I seed irradiation model was established, and cell viability and miRNA microarray assays were performed before and after exposure to the 125I seeds. Cell proliferation was inhibited, and miRNA expression was substantially altered by irradiation exposure. The inhibition of cell proliferation was positively correlated with increased radiation doses, with cells showing the highest total radiation dose 7 days after irradiation. A total of 2549 miRNAs were detected in the SW1353 cells after exposure to 6 Gy of radiation, which included 189 differentially expressed miRNAs (98 upregulated and 91 downregulated). Four miRNAs were found to play important roles in the inhibition of cell proliferation after irradiation exposure, including miR-1224-5p, miR-492, miR-135b-5p, and miR-6839-5p. The target genes of the associated miRNAs mentioned were vascular endothelial growth factor A (VEGFA), C-X-C motif chemokine 12 (CXCL12), mitogen-activated protein kinase kinase kinase kinase 3 (MAP4K3), and apoptosis facilitator Bcl-2-like protein 14 (BCL2L14). Hence, the mitogen-activated protein kinase signaling pathway may be involved in how chondrosarcoma cells respond to 125I seed irradiation.

碘125种子辐照下人软骨肉瘤SW1353细胞的细胞增殖和MicroRNA表达谱分析。

软骨肉瘤是成人第二大最常见的骨恶性肿瘤,通常对传统的化学疗法和放射疗法有抵抗力。已经探索了永久植入碘125(125I)种子来治疗多种癌症的方法。在这项研究中,目的是研究125I种子辐照对人软骨肉瘤SW1353细胞的增殖和microRNA(miRNA)作用。首先,建立了新的体外125I种子辐照模型,并在暴露于125I种子之前和之后进行了细胞活力和miRNA微阵列分析。细胞增殖受到抑制,miRNA表达因照射而显着改变。细胞增殖的抑制与辐射剂量的增加呈正相关,照射后7天细胞显示最高总辐射剂量。暴露于6 Gy辐射后,在SW1353细胞中总共检测到2549个miRNA,其中包括189个差异表达的miRNA(98个上调和91个下调)。发现四种miRNA在辐射暴露后的细胞增殖抑制中起重要作用,包括miR-1224-5p,miR-492,miR-135b-5p和miR-6839-5p。提到的相关miRNA的靶基因是血管内皮生长因子A(VEGFA),CXC基序趋化因子12(CXCL12),促分裂原活化蛋白激酶激酶激酶激酶激酶3(MAP4K3)和凋亡促进因子Bcl-2-样蛋白14( BCL2L14)。因此,丝裂原激活的蛋白激酶信号转导途径可能与软骨肉瘤细胞如何响应125 I种子辐射有关。暴露于6 Gy辐射后,在SW1353细胞中总共检测到2549个miRNA,其中包括189个差异表达的miRNA(98个上调和91个下调)。发现四种miRNA在辐射暴露后的细胞增殖抑制中起重要作用,包括miR-1224-5p,miR-492,miR-135b-5p和miR-6839-5p。提到的相关miRNA的靶基因是血管内皮生长因子A(VEGFA),CXC基序趋化因子12(CXCL12),促分裂原活化蛋白激酶激酶激酶激酶激酶3(MAP4K3)和凋亡促进因子Bcl-2-样蛋白14( BCL2L14)。因此,丝裂原激活的蛋白激酶信号转导途径可能与软骨肉瘤细胞如何响应125 I种子辐射有关。暴露于6 Gy辐射后,在SW1353细胞中总共检测到2549个miRNA,其中包括189个差异表达的miRNA(98个上调和91个下调)。发现四种miRNA在辐射暴露后的细胞增殖抑制中起重要作用,包括miR-1224-5p,miR-492,miR-135b-5p和miR-6839-5p。提到的相关miRNA的靶基因是血管内皮生长因子A(VEGFA),CXC基序趋化因子12(CXCL12),促分裂原激活蛋白激酶激酶激酶激酶3(MAP4K3)和凋亡促进因子Bcl-2-样蛋白14( BCL2L14)。因此,丝裂原激活的蛋白激酶信号转导途径可能与软骨肉瘤细胞如何响应125 I种子辐射有关。其中包括189个差异表达的miRNA(98个上调和91个下调)。发现四种miRNA在辐射暴露后的细胞增殖抑制中起重要作用,包括miR-1224-5p,miR-492,miR-135b-5p和miR-6839-5p。提到的相关miRNA的靶基因是血管内皮生长因子A(VEGFA),CXC基序趋化因子12(CXCL12),促分裂原激活蛋白激酶激酶激酶激酶3(MAP4K3)和凋亡促进因子Bcl-2-样蛋白14( BCL2L14)。因此,丝裂原激活的蛋白激酶信号转导途径可能与软骨肉瘤细胞如何响应125 I种子辐射有关。其中包括189个差异表达的miRNA(98个上调和91个下调)。发现四种miRNA在辐射暴露后的细胞增殖抑制中起重要作用,包括miR-1224-5p,miR-492,miR-135b-5p和miR-6839-5p。提到的相关miRNA的靶基因是血管内皮生长因子A(VEGFA),CXC基序趋化因子12(CXCL12),促分裂原激活蛋白激酶激酶激酶激酶3(MAP4K3)和凋亡促进因子Bcl-2-样蛋白14( BCL2L14)。因此,丝裂原激活的蛋白激酶信号转导途径可能与软骨肉瘤细胞如何响应125 I种子辐射有关。包括miR-1224-5p,miR-492,miR-135b-5p和miR-6839-5p。提到的相关miRNA的靶基因是血管内皮生长因子A(VEGFA),CXC基序趋化因子12(CXCL12),促分裂原激活蛋白激酶激酶激酶激酶3(MAP4K3)和凋亡促进因子Bcl-2-样蛋白14( BCL2L14)。因此,丝裂原激活的蛋白激酶信号转导途径可能与软骨肉瘤细胞如何响应125 I种子辐射有关。包括miR-1224-5p,miR-492,miR-135b-5p和miR-6839-5p。提到的相关miRNA的靶基因是血管内皮生长因子A(VEGFA),CXC基序趋化因子12(CXCL12),促分裂原激活蛋白激酶激酶激酶激酶3(MAP4K3)和凋亡促进因子Bcl-2-样蛋白14( BCL2L14)。因此,丝裂原激活的蛋白激酶信号转导途径可能与软骨肉瘤细胞对125 I种子辐射的反应有关。
