Description

A kind of molecular marker can be used for dog Diagnosis of Breast Tumor and Index for diagnosis
Technical field
The present invention relates to dog tumor of breast detection technique fields, can be used for dog tumor of breast more particularly, to one kind and examine Disconnected and Index for diagnosis molecular marker.
Background technique
Dog tumor of breast is the highest tumor disease of bitch disease incidence, is mainly in 6~11 years old person in middle and old age's bitch, wherein About 30%~50% is pernicious.Since environmental factor or genetic cause lead to occur lump in mammary gland, clinic is referred to as For tumor of breast.A large number of studies show that hormone can be largely affected by the generation of dog tumor of breast, as estrogen, progestational hormone, Growth hormone etc. will affect the generation of malignant tumour.The study found that dog suffers from the disease incidence of tumor of breast with heat time digital display Work increases, and sterilization operation is carried out after first heat can effectively limit tumor of breast occurrence probability.
Society is developing, and times is changing moves, and pet dog comes into the family of common people, with the increase at dog age, The probability for suffering from tumor of breast also slowly increases or even threat to life, and the pathogenesis for studying dog tumor of breast is extremely urgent, finds Reliable and effective treatment method, to improve the survival rate of pet dog only and the existence time limit.In addition, pet dog is as companion animals, It is co-located in identical living environment with the mankind, there is similar life habit, eating habit, the carcinogenic factor touched also has General character, and the various biologicallies of dog tumor of breast, cell sign, antigenic type etc. are similar to people, therefore, study dog Tumor of breast can not only be beneficial to veterinary clinic, also can provide some thinkings and foundation for mankind's medical oncology.
The maximum feature of malignant tumour is exactly infiltration and transfer, and the final treatment failure of tumor patient is caused to welcome death. Grasping its complete mechanism of action is also the common target and wish of clinical practitioners.The infiltration metastasis of tumour is one complicated Pathophysiological process.In this process, the transforming growth factor-β (transforming of normal stroma cell secretion Growth factor- β, TGF-β) promote tumour cell that Epithelial and stromal Phenotypic Change (epithelial-mesenchymal occurs Transition, EMT), so that tumour cell is lost the adhesive attraction and epithelial polarity of cell, the ability for being migrated and being invaded, To promote tumor cell invasion blood vessel, final tumour cell enters blood circulation threat to life.
The tumour cell to fall off from primary tumor continues into the circulatory system of body, becomes circulating tumor cell (ci Rculating tumor cells, CTCs), it is possible that developing into the transfer stove of distant place.Tumour cell can pass through change Peritumoral tissues microenvironment and modify etc. approach to own face antigen to escape the monitoring of body immune system, identification And attack, continue merisis, the i.e. immunologic escape of tumour, it is final that tumor cell migration to distal end target organ carries out infinite multiplication Form transfer stove.
Currently, surgical resection is that pet clinically applies a kind of most methods.There is physical condition and spiritual shape The dispirited dog of state implements to perform the operation again after need to waiting until stable disease;Bigger for the age or weaker constitution suffers from dog, then mostly not It is proposed with the mode of surgical resection;If shifting, it is recommended that conservative therapy;But it is some suffer from dog thoroughly extract it is primary There is the case where recurring and shifting again after tumour, often leads to suffer from dog death.Chemotherapy at present can only be as a kind of complementary Treatment is used in the case where there is malignant tumour or the apparent situation of transfer.Currently, pet clinically chemotherapy apply compared with More but traditional anti-tumor drugs plays drug effect and needs very high blood concentration, and the selectivity acted on is poor, is easy to normal Histocyte generate lethal effect.Radiotherapy is that a kind of local therapeutic approaches of tumour are treated using radioactive ray, can be made For a kind of auxiliary treatment means after the operation excision of essential dog tumor of breast.Targeted therapy is a kind for the treatment of in cellular level Method, neoplasm targeted therapy means mainly include cell factor, adoptive cell, monoclonal antibody, gene therapy etc. at present.
The selection of the above various treatment methods is mostly to assess to suffer from tumor of breast dog only by the clinical experience of pet doctor Prognosis situation, sensitivity is lower, for malignant tumour prognosis assessment still without reliable marker, therefore, find special Property is strong, and the dog tumor of breast prognostic marker of high sensitivity is necessary.
It is cured clinically in people, due to the shortage of tumor prognosis marker, most breast cancer patients receive excessive Chemotherapy has caused many side effects, including leukaemia, heart disease and severe infections.And a part need the patient of chemotherapy without Method is given treatment in time, leads to tumour metastasis and recurrence, causes death.Therefore, suitable tumor prognosis marker will be to patient is judged No to need to receive adjuvant treatment, improving patient's survival rate has great significance.
Pet clinically, tumour it is good it is pernicious be an important factor for judging dog tumor of breast prognosis.And detect tumour mark Will object can help to judge the property of tumour and prognosis situation, but pet clinic is more rare at present.Infiltration, the transfer of tumour relate to And to multifactor and multiple the step of recurring, there is the different factors to participate in each stage, for example, cell adhesion because Son, matrix metalloproteinase etc..
The tumor markers clinically used at present have many flaws: 1. specificity and sensitivity are not high enough, exist Mistaken diagnosis or the case where fail to pinpoint a disease in diagnosis;2. testing cost is higher, Combining diagnosis is difficult to popularize in common physical examination;3. certain tumours are not yet The marker of specificity.
