The formation of image of molecule can catch breast cancer

The formation of image of molecule can catch breast cancer " The clues "
It is reported ' Peak reporter's king's intelligent tip money gull of dawn of reporter's clothing) Subsidiary fourth hospital of medical university of Kazakhstan explains what the loyal professor of the treasure finished " The formation of image of molecule of malignant tumour is studied " ,Have announced the changes and secrets at cells, inferior cell, genetic molecule level when breast cancer takes place. This achievement obtained the first prize of progress prize in science and technology of medical and health of Heilongjiang Province a few days ago.

The molecule image that emerged in U.S.A. at the end of the 1990s of last century is studied, what carried on physiology, pathologic course within the life or organism at the molecule and cell level is not the creating real-time formation of image, can make accurate diagnosis to disease promptly before the organism has not changed morphology yet.

Explain the seminar of loyal professor of the treasure and employ the technology of the optical member's formation of image, has announced the mechanism that breast cancer grows and shifts in early days. Discover, the epidermis growth factor receptor (EGFr) in breast cancer cells Highly express, it is the positive correlation that EGFr expresses the malignant intensity in level and breast cancer. The seminar utilizes nearing epidermis growth factor (EGF) of the fluorogenic mark of infrared ray The molecule probe, carries on the formation of image and " exposes " to the protein product of the gene expression of breast cancer ,Advance the diagnosis time of breast cancer greatly, make it found before not forming lump yet.

Explain the intersection of treasure and loyal professor,etc., utilize nearly probe, member of infrared ray, to high specificity that tumour organize, to early to carry on the intravital formation of image existing lymph node that inspection means find or suspect highly, can lock the little focus that the naked eye can't be judged in time. Research reveals, EGF-Gy5.5 fluorogenic probes can be " kept a close watch on " Breast cancer and epidermis growth factor receptor (EGFr) ,Carry on the specificity apparently to look like, pass the appearance of the optical member's formation of image of living subject this " piercing eye " ,The ones that catch breast cancer " The clues " .

Meanwhile, the seminar still verifies, forms and supplies nutrition without the new born blood vessel through animal's experiment, breast cancer will no longer increase while reaching the diameter or thickness of 1 millimetre 2 millimetre. So long as block the supply blood vessel of tumour in early days, the breast cancer focus will be " died of hunger " . So, appraise the blood vessel new students of tumour and adopt intervening in early days and have important clinical meanings.
