Expression levels and clinical significance of miR-203 and miR-133b in laryngeal carcinoma.

ABSTRACT: The present study aimed to investigate the expression levels and clinical significance of microRNA (miR)-203 and miR-133b in laryngeal carcinoma. A total of 154 patients with laryngeal carcinoma (research group) along with 100 healthy individuals (control group) were enrolled in the study. The patients were admitted to Yidu Central Hospital of Weifang (Weifang, China) from February 2016 to October 2018. Fasting venous blood (5 ml) was extracted from all subjects to determine the expression levels of serum miR-203 and miR-133b by reverse transcription-quantitative polymerase chain reaction (PCR) and to compare them among patients with different pathological characteristics. Receiver operating characteristic (ROC) curves were plotted to analyze the diagnostic values of miR-203 and miR-133b for laryngeal carcinoma. The research group showed significantly lower expression levels of miR-203 and miR-133b than the control group (P<0.05). According to ROC curve analysis, when the cut-off value was 0.659, the sensitivity and specificity of miR-203 in diagnosing laryngeal carcinoma were 60.00 and 90.26%, respectively, whereas when the cut-off value was 1.398, the sensitivity and specificity of miR-133b were 55.00 and 87.66%, respectively. The sensitivity and specificity of the joint detection were 70.00 and 83.77%, respectively, when the cut-off value was 0.416. In the research group, miR-203 was expressed significantly different in patients with different pathological stages and tumor types (P<0.050). The expression of miR-133b varied significantly in patients with different pathological stages, differentiation degrees and lymph node metastasis (P<0.050). In conclusion, miR-203 and miR-133b were expressed at low levels in patients with laryngeal carcinoma. The expression of miR-203 was related to tumor-node-metastasis (TNM) stage and tumor type, whereas the expression of miR-133b was related to TNM stage, differentiation degree, as well as lymph node metastasis. Joint detection of miR-203 and miR-133b is expected to be an excellent marker for the diagnosis and treatment of laryngeal carcinoma.

Project description:Cutaneous squamous cell carcinoma (CSCC) is the second most widespread cancer in humans and its incidence is rising. These tumours can evolve as diseases of poor prognosis, and therefore it is important to identify new markers to better predict its clinical evolution.We aimed to identify the expression pattern of microRNAs (miRNAs or miRs) at different stages of skin cancer progression in a panel of murine skin cancer cell lines. Owing to the increasing importance of miRNAs in the pathogenesis of cancer, we considered the possibility that miRNAs could help to define the prognosis of CSCC and aimed to evaluate the potential use of miR-203 and miR-205 as biomarkers of prognosis in human tumours.Seventy-nine human primary CSCCs were collected at the University Hospital of Salamanca in Spain. We identified differential miRNA expression patterns at different stages of CSCC progression in a well-established panel of murine skin cancer cell lines, and then selected miR-205 and miR-203 to evaluate their association with the clinical prognosis and evolution of human CSCC.miR-205 was expressed in tumours with pathological features recognized as indicators of poor prognosis such as desmoplasia, perineural invasion and infiltrative growth pattern. miR-205 was mainly expressed in undifferentiated areas and in the invasion front, and was associated with both local recurrence and the development of general clinical events of poor evolution. miR-205 expression was an independent variable selected to predict events of poor clinical evolution using the multinomial logistic regression model described in this study. In contrast, miR-203 was mainly expressed in tumours exhibiting the characteristics associated with a good prognosis, was mainly present in well-differentiated zones, and rarely expressed in the invasion front. Therefore, the expression and associations of miR-205 and miR-203 were mostly mutually exclusive. Finally, using a logistic biplot we identified three clusters of patients with differential prognosis based on miR-203 and miR-205 expression, and pathological tumour features.miR-205 and miR-203 tended to exhibit mutually exclusive expression patterns in human CSCC. This work highlights the utility of miR-205 and miR-203 as prognostic markers in CSCC.
