Abstract

The invention discloses application of long-chain non-coding RNA LINC00336 as a biomarker in preparing a lung squamous cell carcinoma prognosis detection preparation. The expression level of long-chain non-coding RNA LINC00336 in a lung squamous cell carcinoma patient can be detected, a powerful molecular biology basis is provided for prognostic prediction to the lung squamous cell carcinoma patient, and long-chain non-coding RNA LINC00336 has profound clinical significance and good popularization performance.

Description

technical field [0001] The invention belongs to the field of tumor molecular biology, and specifically relates to the application of long-chain non-coding RNA LINC00336 as a biomarker in the preparation of prognostic reagents for lung squamous cell carcinoma. Background technique [0002] Lung cancer is one of the malignant tumors with the highest morbidity and mortality in the world. Squamous cell carcinoma of the lung, or squamous cell carcinoma, is the most common type of lung cancer. It is a malignant epithelial tumor derived from the bronchial epithelium. For 40% to 51% of recurrent lung cancer, the 5-year survival rate is still lower than 15% after comprehensive treatment such as surgery, radiotherapy and chemotherapy. At present, there is no reference standard for the prognosis of patients with squamous cell carcinoma of the lung, and there is no specific index, which is far from meeting the needs of determining the prognosis of patients with squamous cell carcinoma o...
