Inhibition effect of miR-150 on the progression of oral squamous cell carcinoma by data analysis model based on independent sample T-test.

Abstract

To explore the influence of mir-150 (M-150) ornithine decarboxylase (ODC) or inhibition in the development of oral squamous cell carcinoma (OSCC), the malignant tumor (MT) textures removed by surgical resection of maxillofacial tumors in patients with OSCC and the normal neighbor oral textures were collected. Then human OSCC cal-27 cell line was cultivated in vitro. The expression differences of M-150 in MT textures, neighbor textures and cal-27 cells were explored by fluorescence polymerase chain reaction (PCR). Cal-27 cells were transfected with M-150 mimic, M-150 inhibitor (M-150-I) and negative control of different concentrations, respectively, to test the transfection rate. After transfection (AF) with the optimum transfection concentration, the migration rate of transfected cells was explored by cell scratch test. Transwell assay was used to detect the change of aggression rate of transfected cells. Finally, independent sample t-test model was used to explore and compare the results between groups. The results manifested that the expression of M-150 (Eom) in MT textures and cal-27 cells was obviously less than that in neighbor normal textures (P < 0.05). Transfection rate results manifested that M-150 mimic of 100 nmol/L and M-150-I of 50 noml/L had the best efficiency. AF, cell migration and aggression (M&A) rates in the M-150 mimic group were obviously less than those in the negative control group (CP) (P < 0.05), while those in the M-150-I group were obviously upper (P < 0.05), which indicates that the over Eom could inhibit the M&A of OSCC cells, and thus play an effect in inhibiting the development of OSCC.
