ABSTRACT
Objective:
To study the expression and significance of long noncoding RNA (lncRNA) LINC00657 in diffuse-type adenocarcinoma of esophagogastric junction (AEG).Methods:
RT-PCR was used to determine the expression of LINC00657 in AEG tissues and AEG patient-derived tumor cells (PDCs). The expression of E-cadherin in AEG tissues and PDCs was detected. The Kaplan-Meier method was used to evaluate the correlation of LINC00657 expression with the overall survival (OS) of patients.Results:
LINC00657 was highly expressed in AEG tissues [(1.41±0.12) vs. (0.61±0.11), t=276.038, P<0.01] and PDCs, while E-cadherin was significantly down-regulated. The expression of LINC00657 was retated to tumor diamer, invassion depth, lymph node metastasis, TNM staging (all P<0.05) In Kaplan-Meier analysis, high levels of LINC00657 were associated with poor prognosis for patients with diffuse-type AEG. In addition, a significant inverse relationship was observed between LINC00657 and E-cadherin expression ( r=-0.529, P<0.001).Conclusions:
Elevated expression of LINC00657 in diffuse-type AEG tissues is associated with poor prognosis and may confer a malignant phenotype upon tumor cells.
