Cancer&Entry Information
| Cancer Name | esophageal squamous cell carcinoma |
| ICD-0-3 | NA |
| Methods | Microarray, qPCR, Western blot |
| Sample | The esophageal cancer cell line EC109 and human esophageal epithelial cell Het-1A, tumor samples of ESCC tumors and adjacent normal tissues |
| Expression Pattern | down-regulated |
| Function Description | LincRNA-p21 expression level was remarkably lower in tumor tissues versus nontumor tissues and lower in EC109 cells versus Het-1A cells. Statistical analysis found that LincRNA-p21 might enhance the risk of ESCC. We observed that LincRNA-p21 was expressed both in the nucleus and cytoplasm, and a larger proportion of LincRNA-p21 was observed in the cytoplasm. The results demonstrated that upregulating the expression of LincRNA-p21 could inhibit cell proliferation, migration, invasion, and the transition of cell cycle from G1 and promoted apoptosis of EC109. Then, we found that LincRNA-p21 promotes the expression of p21. Decreasing the level of p21 revealed that cell-cycle arrest was restored. Pathway analysis found p53 pathway was downregulated, and upregulation of LincRNA-p21 inhibited the expression of cyclin D. |
