已知神经酰胺合酶(Cer Ss)与肿瘤的生物学行为特别是细胞凋亡相关,但不同Cer Ss在不同肿瘤中的具体作用仍不清楚。Mojakgomo等探究了Cer Ss4和Cer Ss5与全球两大高发癌症——子宫内膜癌和结肠癌的关系。研究者首先分别使用阿那曲唑和5-氟尿嘧啶诱导子宫内膜癌细胞及其相应非癌细胞、结肠癌细胞及其相应非癌细胞凋亡,之后采用荧光激活细胞分选术确定细胞凋亡数,再提取经凋亡处理和未经调亡处理的细胞的总RNA,检测Cer Ss4和Cer Ss5 m RNA的相对表达水平。采 It is known that ceramide synthase (Cer Ss) is related to the biological behavior of tumor, especially apoptosis. However, the specific role of different Cer Ss in different tumors remains unclear. Mojakgomo et al explored the relationship between Cer Ss4 and Cer Ss5 and two of the world’s top cancer-endometrial and colon cancers. The researchers first used anastrozole and 5-fluorouracil to induce apoptosis of endometrial cancer cells and their corresponding non-cancer cells, colon cancer cells and their corresponding non-cancer cells, respectively, followed by fluorescence activated cell sorting to determine the number of apoptotic cells Then the total RNA of apoptotic and non-apoptotic cells was extracted to detect the relative expression level of Cer Ss4 and Cer Ss5 m RNA.
