The expression of LRIG1 was decreased, while the expression of EGFR was increased in the majority of bladder cancer, and the ratio of EGFR/LRIG1 was increased in tumors versus normal tissue.
The positive expression rate of Fascin-1 in cancer tissue and normal tissue was 70.5% (43/61) and 13.1% (8/61), respectively, which indicated cancer tissue much higher than normal tissue (P < 0.05); for LRIG1, the positive expression rate was 54.1% (33/61) and 82.0% (50/61) for tumor tissue and normal tissue with statistical difference (P < 0.05); Fascin-1-positive expression was associated with tumor diameter (P < 0.05) and mediastinal lymph node metastasis (P < 0.05).
The present study was conducted to investigate the possible prognostic value of molecular markers LRIG1‑2 and LIM domain 7 protein (LMO7) in vulvar squamous cell carcinoma (VSCC) and their possible correlation to human papilloma virus (HPV)‑ and p16INK4a‑status of the tumors.
These findings suggest that LRIG1 exerts important tumor-suppressive effects in EGFR-mutant NSCLC and has the potential to become a novel therapeutic target for EGFR-mutant NSCLC.
We found that over-expression of LRIG1 inhibits cell proliferation and colony formation and tumor growth, while knockdown of LRIG1 promotes cell proliferation and colony formation.
