Description

The application of cardiac muscle troponin I in preparation inhibition tumour medicine
Technical field
The present invention relates to proteinic new purposes and expression thereof, particularly relate to the new purposes and the vivoexpression method thereof of cardiac muscle troponin I.
Background technology
Malignant tumor is the most serious class disease of harm humans health.The common method of treatment malignant tumor has at present: surgical operation therapy, chemical medicinal treatment, radiotherapy, biotherapy and Chinese medical and herbal therapy.Wherein commonly used with surgical operation therapy, chemical medicinal treatment, radiotherapy.Surgical operation therapy is as the first-selection and the major programme of most of oncotherapys, makes that countless tumor patients rehabilitate, life-saving or improved quality of life.But aspect oncotherapy, surgical operation therapy only is applicable to the patient of certain condition and scope, and because tumor can recur and shift, excision can both not reach the purpose of radical cure.Extremely important and requisite effect is also being brought into play in chemical medicinal treatment and the radiocurable tumor treatment aspect that is used in, and also in continuous development.But at present chemotherapeutics therapy of using and radiotherapy all have infringement to all active proliferative cells in the health, as hemopoietic system, gastrointestinal tract etc., so symptoms such as the patient of chemicotherapy often has hemogram reduction, gastrointestinal hemorrhage, feels sick, vomitings.And owing to being subjected to the restriction that many-sided reasons such as drug resistance appear in patient's body and spiritual aspect holding capacity and tumor cell, chemicotherapy can not kill all tumor cells, for the recurrence of tumor and the deterioration of transfer and disease have stayed hidden danger.Biotherapy and Chinese medical and herbal therapy also are the antineoplastic reasonable method, but require further study to improve curative effect.Therefore, the exploitation have obvious therapeutic effect, safety antitumor drug be the extremely urgent task that the world of medicine faces.
Studies show that the unrestricted invasive growth of malignant entity tumor and transfer thereof depend on the continuous generation of neovascularity, can suppress growth of tumor significantly so suppress angiogenesis.Suppress angiogenesis, the blood supply of blocking-up tumor body is the New Policy that is different from conventional antineoplaston, is also referred to as " tumor starvation ", has become the focus of antineoplaston research.Under the normal physiological state, ovulating except female reproductive system, corpus luteum generates, and processes such as pregnancy have outside the of short duration new vessels generative process, and adult vascular system hypertrophy is in relative static conditions.But in tumor tissues, for adapting to the quick growth of tumor tissue, angiogenesis is very active, in time to be tumor tissue growth supply blood.Blood capillary in tumor tissues source has two kinds: a kind of is the VEGF that tumor cell etc. produces, and induces the tumor body to generate blood capillary; Another kind is that the host blood vessel that remains in the tumor body gradually becomes tumor vessel, both the tumorization of host blood vessel.Different with normal blood vessels, tumor vascular vascular endothelial cell is imperfect, and basement membrane is sparse and be easy to reveal.Behind the tumor-blood-vessel growth no longer further differentiation reconstruct into tremulous pulse and vein, no smooth muscle and teleneuron belong to passive blood vessel, its blood flow body that places one's entire reliance upon circulates.Newborn blood capillary is a first stop tumor-infiltrated and that shift, and tumor cell enters blood circulation to metastasis by the tumor wall of micrangium.
Entity tumor growth needs a large amount of blood supplies.Many experimentatioies confirm to suppress neovascularity generation in the animal body, can be cut to the blood supply that tumor growth provides nutrient effectively, make the atrophy of tumor body so that disappear.The application of anti-neovascularization medicaments TNP-470 and anti-bFGF, VEGF monoclonal antibody, the competitive blocking VEGF signal conduction of saltant vegf receptor FlK-1, α V β 3 overexpression inducing endothelial cell apoptosis and the formation of the special inhibition tumor neogenetic blood vessels of Angiostatin etc., all can suppress tumor growth, be a kind of novel, promising antitumor drug, can remedy the limitation of current clinical cancer therapy means and replace the part treatment means.Because this class medicine is to reach by the formation that suppresses new vessels to suppress tumor growth, and the growth of people's normal tissue cell does not rely on the generation of new vessels, so normal structure is not almost had toxic and side effects.This class medicine does not directly act on tumor cell, so the inhibition tumor has broad spectrum activity and does not develop immunity to drugs, be current effective, safe, promising antitumor drug of generally acknowledging in the world, be mainly used in original position and shift the treatment of solid tumor and the operative treatment of auxiliary tumor, also can be used for preventing the recurrence and the transfer of tumor.Therefore, develop a kind of inhibiting antitumor drug of blood vessel hyperplasia that has, aspect the preventing and treating of malignant tumor, have the important clinical meaning.
