RESUMEN
AIM:To investigate the role and molecular mechanism of long noncoding RNA LINC00987 in the apoptosis of acute myeloid leukemia(AML)cells induced by antitumor drugs.METHODS:The LINC00987 expression in AML was detected by RT-qPCR.The Molm13 cells with stable knockdown of LINC00987 gene(shLINC00987)were constructed,and the effect of low LINC00987 expression on the apoptosis of AML cells induced by cytarabine was detected by annexin V/PI staining.Signaling pathway enrichment of LINC00987-coexpressed genes was performed to analyze the ef-fect of LINC00987 expression on cytochrome family genes.RESULTS:Compared with healthy individual group,the ex-pression of LINC00987 was significantly down-regulated in AML cell lines and patients,but highly up-regulated in the complete remission group after anti-AML treatment.In addition,low LINC00987 expression was associated with poor prog-nosis among the patients with AML.The LINC00987 expression in AML cell lines Molm13 and MV411 was significantly induced by antitumor drugs such as cytarabine,doxorubicin,arsenic trioxide,and venetoclax.Meanwhile,LINC00987 down-regulation could inhibit the apoptosis of Molm13 cells induced by cytarabine.The LINC00987-coexpressed genes were enriched in cytochrome P450(CYP450)-mediated oxidative stress pathways,and the LINC00987 expression was positively correlated with the expression of CYP450 family genes CYP11B1,CYP2U1 and CYP2C9.Down-regulation of LINC00987 could inhibit the mRNA expression of CYP11B1,CYP2U1 and CYP2C9 induced by cytarabine.CONCLU-SION:Long noncoding RNA LINC00987 can be used as a prognostic marker for AML and may promote cytarabine-in-duced AML cell apoptosis through CYP450-mediated oxidative stress pathways.
RESUMEN
Objective To foster the ethics in biomedical research and increase the integrity in research staffs.Methods The quantitative approaches to measurement and evaluation of scientific research integrity in recent years were proposed and reviewed.Results By taking effective measurements,management of scientific research ethics and post hoc salvation procedure were established to increase the integrity of scientific researchers.Conclusion Through improving the management of scientific research and generating a friendly environment towards scientific ethics,healthy development of medical scientific research can be achieved and research misbehavior can be minimized.
