Furthermore, over-expression of LRRC3B was reported to inhibit cell cycle proliferation, invasion, and progression of lung and breast cancer cells, suggesting that LRRC3B may be a useful marker for the diagnosis and prognosis of BRCA and non-small cell lung cancer (NSCLC) (8, 9). The gene discussed is LRRC3B; the disease is non-small cell lung carcinoma.
