Abstract:
BACKGROUND:During the occurring and developing of tumor, tumor-educated platelets mRNA profiles were altered. Since platelets are anuclear, the level of mRNAs is probably post-transcriptional regulated by the splicing maturation of pre-mRNA and alternative splicing. Apoptotic chromatin condensation inducer 1 (ACIN1) has been shown to be a component of a splicing-dependent multiprotein exon junction complex (EJC) and was involved in mRNA metabolism associated with splicing. This study analyzed the expression of ACIN1 mRNA in platelets, and explored its potential as a biomarker of lung cancer.
METHODS:156 patients with lung cancer and 58 healthy controls in Shandong Cancer Hospital were collected. We isolated platelet pellets by low-speed centrifugation and extracted total RNA. The expression of ACIN1 mRNA in platelets was detected by RT-PCR, the results were analyzed statistically. And the relationship between expression of ACIN1 mRNA and clinical factors were also analyzed.
RESULTS:The expression level of ACIN1 mRNA in platelets of patients with lung cancer was significantly higher than that in platelets of healthy controls (P=0.015). The ROC curve showed that the area under the curve of ACIN1 mRNA for detecting lung cancer were 0.608. The expression of ACIN1 mRNA in platelets of lung cancer has no significant relationship with age, gender, pathological type and metastasis or not (P>0.05).
CONCLUSIONS:ACIN1 mRNA was highly expressed in platelets of lung cancer patients, and the detection of its expression level might have potential clinical value for the diagnosis of lung cancer.
