法國(guó)里爾大學(xué)Adriaenssens等的研究表明,，以神經(jīng)生長(zhǎng)因子(NGF,，神經(jīng)營(yíng)養(yǎng)因子之一)為靶點(diǎn)，可抑制乳腺癌細(xì)胞的增殖,、存活和轉(zhuǎn)移,，故NGF是乳腺癌的潛在治療靶點(diǎn)《癌癥研究》（Cancer Research）。
研究者對(duì)一系列活檢組織的分析表明,，NGF在絕大多數(shù)人類乳腺腫瘤中都有廣泛表達(dá),，抗NGF免疫反應(yīng)主要集中在上皮性癌細(xì)胞。此外,，在異種移植人類乳腺癌細(xì)胞的免疫缺陷鼠中也觀察到,，抗NGF抗體或抗NGF的小干擾RNA治療可抑制腫瘤的生長(zhǎng)和轉(zhuǎn)移。這些直接以NGF為靶點(diǎn)的治療在引起細(xì)胞增殖下降的同時(shí),，還可促進(jìn)細(xì)胞凋亡和抑制腫瘤血管生成,。
乳腺癌靶向治療是分子水平的治療方式，目前已有多種靶向藥物應(yīng)用于臨床,，神經(jīng)生長(zhǎng)因子在乳腺腫瘤的生長(zhǎng)和轉(zhuǎn)移過程中有其特定作用,，有望成為新的靶向治療靶點(diǎn)。（來源：中國(guó)醫(yī)學(xué)論壇報(bào) 張瑾）

We show here that nerve growth factor (NGF), the prototypic neurotrophin, can be targeted in breast cancer to inhibit tumor cell proliferation, survival, and metastasis. Analysis of a series of biopsies revealed widespread expression of NGF in the majority of human breast tumors, with anti-NGF immunoreactivity concentrated in the epithelial cancer cells. Moreover, immunodeficient mice xenografted with human breast cancer cells and treated with either anti-NGF antibodies or small interfering RNA against NGF displayed inhibited tumor growth and metastasis. Such treatments directed against NGF induced a decrease in cell proliferation with a concomitant increase in apoptosis of breast cancer cells and an inhibition of tumor angiogenesis. Together, these data indicate that targeting NGF in breast cancer may have therapeutic ramifications. [Cancer Res 2008;68(2):346–51]
