LINC01638 lncRNA promotes the proliferation, migration and invasion of prostate carcinoma cells by interacting with Notch1.

LINC01638 lncRNA is known as an oncogenic lncRNA in triple negative breast cancer. However, the role of LINC01638 lncRNA in other diseases is unknown. In the present study we observed that plasma levels of LINC01638 lncRNA and Notch1 were upregulated in prostate carcinoma patients comparing with healthy controls. LINC01638 lncRNA and Notch1 were positively correlated in prostate carcinoma patients but not in healthy controls. Upregulation of LINC01638 lncRNA distinguished prostate carcinoma patients from healthy controls. LINC01638 lncRNA overexpression in prostate carcinoma cells led to upregulated Notch1 expression. Notch1 overexpression also led to increased expression level of LINC01638 lncRNA. Both LINC01638 lncRNA and Notch1 overexpression promoted the proliferation, migration and invasion of prostate carcinoma cells. We concluded that LINC01638 lncRNA might promote the proliferation, migration and invasion of prostate carcinoma cells by interacting with Notch1.
