| Disease Name: | Squamous Cell Carcinoma of Head and Neck |
| Sample: | tumor tissues and their matched adjacent normal tissues, cell lines(Tca8113, SCC9, SCC25, CAL27, HN12, HSU3, FADU,NHOK) |
| Dysfunction Pattern: | Interaction[p53;YAP1] |
| Validated Method: | qRT-PCR//Western Blot//Luciferase Report Assay//ChIP |
| Description: | RBM5-AS1 was dramatically Expression[Expression[up-expression]-expression]regulated in OSCC than in the normal tissues (Fig. 1A). We then analyzed the expression of RMB5-AS1 in OSCC cell lines, including Tca8113, SCC9, SCC25, CAL27, HN12, HSU3, FADU, and normal human oral keratinocytes NHOK cell. The results showed that RBM5-AS1 was Expression[Expression[up-expression]-expression]regulated in OSCC comparing to NHOK cells.We also found that RBM5-AS1 regulates the level of miR-1285-3p as a competitive endogenous RNA (ceRNA), therefore regulate the expression level of an oncogene-YAP1, a target of miR-1285-3p. |
| Causality: | Yes |
| Causal Description: | KnockExpression[down-expression] of RBM5-AS1 significantly inhibited cell proliferation compared to the negative control groExpression[Expression[up-expression]-expression] in both cell lines (Fig. 3, A and B). Our results from colony forming assay with Tca8113 and SCC9 cells after siRNA transfection also showed that si-RBM5-AS1#1 and si-RBM5-AS1#2 effectively inhibited colony formation (Fig. 3, C and D). |
| Clinical-realted Application: | Subsequently, we used the chi-square test to determine RBM5-AS1 expression and clinicopathological characteristics correlation in OSCC patients. RBM5-AS1 was closely related to the tumor size, differentiation, TNM stage, and lymph node metastasis, but not to the patient's age, sex, and tumor location (Table 1). |
