The splicing factor proline and glutamine rich promotes the growth of osteosarcoma via the c-Myc signaling pathway.

Splicing factor proline- and glutamine-rich (SFPQ) regulates transcripts in skeletal muscle metabolism and tumorigenesis. As osteosarcoma (OS) is the most common malignant bone tumor characterized by genome instability, such as MYC amplification, this study aimed to investigate the role and mechanism of SFPQ in OS. Expression of SFPQ in OS cell lines and human OS tissues was detected using quantitative real-time PCR, western blot, and fluorescence hybridization (FISH) analyses.

Long noncoding RNA expression profiles of the doxorubicin-resistant human osteosarcoma cell line MG63/DXR and its parental cell line MG63 as ascertained by microarray analysis.

Long non-coding RNAs (lncRNAs) are emerging in molecular biology as crucial regulators of cancer. The efficacy of doxorubicin--based chemotherapy in osteosarcoma (OS) is usually limited by acquired drug resistance. To explore the mechanism of chemoresistance of OS in terms of lncRNA, using a human lncRNA-mRNA combined microarray, we identified 3,465 lncRNAs (1,761 up and 1,704 down) and 3,278 mRNAs (1,607 up and 1,671 down) aberrantly expressed in all three sets of doxorubicin-resistant MG63/DXR and their paired parental MG63 cells (fold-change >2.

Integrated interventions for improving negative emotions and stress reactions of young women receiving total hysterectomy.

50% of women had obvious abnormal emotions before hysterectomy and hysterectomy can cause strong mental stress reaction. This study was to investigate the impact of psychological health education based integrated interventions on the preoperative negative emotions and stress of patients younger than 45 years receiving total hysterectomy. Forty patients undergoing total hysterectomy were randomly divided into psychological intervention (PI) group and control group (n=20 per group).
