Description
Technical field
The invention belongs to biomedicine fields, are related to purposes of the gene marker in adenocarcinoma of lung diagnosis and treatment, are specifically related to
Gene marker be LINC02154.
Background technique
Lung cancer is one of highest cancer of the global death rate, no matter its disease incidence of gender and the death rate are respectively positioned on first three
(Siegel RL,Miller KD,Jemal A:Cancer statistics,2015.CA:a cancer journal for
clinicians 2015,65(1):5-29.).Early discovery, early diagnosis, early treatment it is particularly significant in the diagnosis and treatment of lung cancer sufferer and
Necessity, very likely there is transfer of the lung carcinoma cell to other each different organs in advanced lung cancer sufferer, so that suffering from lung cancer
The major reason of person's life quality decline and poor prognosis.Although clinical constantly update pulmonary cancer diagnosis and treatment technology and method
It regenerates, but the whole outcome after lung cancer therapy is still undesirable, the death rate still occupies first of various cancers, patient's
5 annual survival rates are still less than 15%.About 85% the above are non-small cell lung cancer in lung cancer patient, at this stage most effective treatment method
It is early stage patient based on surgical operation therapy, middle and advanced stage patient is using chemicotherapy and the complex treatment of targeting immunization therapy.
Regardless of whether the patient that can be performed the operation, overall survival is all undesirable, seriously affects and endangers human health and life.It is early to find, is early
Diagnosis, early treatment and effective prediction prognosis are particularly significant in lung cancer diagnosis and treatment whole process.
Recently as the attention and further investigation lung cancer occurred with tumour growth mechanism, some important therapy targets
Also it is gradually found, and the precisely trial and breakthrough of targeted therapies, these all bring newly to the diagnosis and treatment of patients with lung cancer
Breach.Due to it has now been found that targeted therapy to the office of the distribution of the limitation of target spot and its crowd exception
It is sex-limited, therefore effective target user's range of relevant treatment method is relatively narrow, there is the tumour growth mistakes that can not change at present
The factors such as heterogeneous and drug resistance in journey, so the therapeutic effect of lung cancer is still faced with stern challenge at present.
Nowadays lung cancer research hotspot field is gradually horizontal toward the relevant Molecular Detection of lung cancer therapy, find new therapy target and
Accurate targeted therapy direction transfer.Research report, genome at least 90%DNA is transcribed, but wherein encoding egg white gene DNA sequence
Column only account for about the 2% of whole genome sequence, and most of transcript is 1ncRNA (long-chain non-coding RNA).LncRNA refers to length
Degree is greater than the non-coding RNA of 200bp, and further research confirms, 1ncRNA cell Proliferation, cell differentiation, chromosome silencing,
Play a key effect (Ponting CP, Oliver PL, Reik W Evolution in the biological processes such as histone modification
And functions of long noncoding RNAs.Cell.2009.136 (4): 629-41.), also develop with disease and cease
Manner of breathing closes.Gene relevant to adenocarcinoma of lung is found, the molecular marker for more having prospect and value is sought, for the hair for disclosing adenocarcinoma of lung
Interpretation of the cause, onset and process of an illness system realizes that the early diagnosis of adenocarcinoma of lung has great importance.
