Embodiment 1

[0031] The synergistic effect of embodiment 1 ligustilide and tamoxifen

[0032] MDA-MB-231 cells were used in the experiment, and the concentration of ligustilide was set at 0, 10, 25, and 50 μmol / L. After 12 hours of pretreatment with ligustilide, they were mixed with 1, 2.5, and 5 μmol / L tamoxifen, respectively. Co-incubated for 72h, and obtained the experimental results by sulforhodamine B staining method (SRB), the results are as follows: figure 1 As shown, ligustilide and tamoxifen alone have almost no effect, but the inhibitory rate gradually increases with the concentration gradually increasing after synergistic use.

Embodiment 2

[0033] The synergistic effect of embodiment 2 Liguscarina A and tamoxifen

[0034] MDA-MB-231 cells were used in the experiment, and the concentration of chuanxionglide A was set from low to high to 0, 50, 100, and 150 μmol / L in turn. Fen co-incubated for 72h, and detected by sulforhodamine B staining method (SRB), the results were as follows: figure 2 As shown, the single citrolactone A has almost no effect on tamoxifen, and the inhibitory rate increases gradually with the concentration gradually increasing after combined use, which is the same as that of figure 1 The results were similar.

Embodiment 3

[0035] Example 3 Effect of ligustilide on ERα protein expression

[0036] MDA-MB-231 cells were used in the experiment. First, they were incubated with ligustilide at a concentration of 0, 10, 25, and 50 μmol / L for 48 hours, and the proteins were separated and collected for Western Blot experiments. The experimental results are as follows: image 3 As shown, as the concentration increased, the expression of ERα protein gradually increased.

Abstract

The invention discloses application of ligustilide to prevention and treatment of breast cancer. A research represents that the ligustilide has a certain inhibition effect on negative and positive breast cancer cells of an estrogen receptor alpha (ERalpha). Furthermore, existing breast-cancer-resisting drugs including tamoxifen and the like in the market mainly have effects on the positive breast cancer cells of the estrogen receptor alpha, but have very slight effects on the negative breast cancer cells of the estrogen receptor alpha; the research provided by the invention represents that the ligustilide can be used for increasing ERalpha protein expression of the breast cancer cells, and furthermore, the ligustilide and the tamoxifen are cooperated to realize the effect of preventing and treating the breast cancer.

Description

technical field [0001] The invention relates to a new application of ligustilide, in particular to the application of ligustilide in preventing and treating breast cancer. Background technique [0002] Breast cancer, also known as "milk stone" and "breast cancer", is one of the most common malignant tumors in women. According to data from Cancer Statistics in 2016, there were 1,685,210 new cases of cancer in the United States in 2015, and 595,690 patients would die of cancer. Among the female cancer incidence rates, breast cancer is the highest rate at 29%, and the mortality rate is second only to lung cancer. second. In China, the incidence of breast cancer is not optimistic. As early as 2013, the data from the China Cancer Registry Annual Report revealed that the average age of female breast cancer in my country was 48.7 years old, 10 years earlier than in Western countries. Among the high incidence cancers in women, breast cancer Cancer has surpassed lung cancer to becom...
