摘    要:给出了乳腺癌病人正常乳腺细胞与癌细胞的拉曼光谱。从实验谱线中得到:癌变细胞的拉曼谱整体变弱, 就相对强度而言, DNA的2个磷酸根骨架峰782,1 084 cm-1和脱氧核糖-磷酸振动峰1 155及1 262 cm-1拉曼谱线明显的减少; 表征A型(DNA)构像的特征峰812 cm-1及谱线979,668 cm-1消失, 并有新峰1 175 cm-1出现, 905 cm-1的谱线增强并有6 cm-1的红移, 这说明DNA的磷酸根骨架有一定的断裂; 从而导致癌细胞的分裂繁殖失去有效的控制。在癌变组织细胞的拉曼谱中还发现了很强的一类与钙硬化密切相关的特征峰960 cm-1; 通过这些特征拉曼谱线的变化, 为癌症的诊断和治疗提供了有力的实验依据。

关 键 词:显微拉曼光谱  乳腺癌细胞  DNA

Abstract:Raman spectra of normal and cancer cell from breast cancer patients are presented. It is reported that all of the Raman lines become weak. The intensities of Raman lines 782 and 1 084 cm~-1 of DNA phosphate group and 1 155 and 1 262 cm~-1 of deoxyribose-phosphate decrease. The spectral lines 812 cm~-1 of A-type DNA and 979 and 668 cm~-1 disappear, and the 905 cm~-1 peak is shifted to lower frequency by 6 cm~-1 . This means that the phosphate backbone of DNA is destroyed to a certain extent and the fissiparity of ~cancer cell can't be controlled effectively. In addition, the authors found a kind of Raman line 960 cm~-1 concerning calcification and sclerosis of cancer cell. The results indicate that Raman spectra may offer the experiment basis for the cancer diagnosis and treatment.
Keywords:Raman microscopy  Breast cancer cell  DNA
