miRNAs expression in four breast cancer cells

To determine the miRNAs’ roles in the tumorigenesis behavior of TNBC, we profiled the global miRNA expression in 2 highly aggressive TNBC cell lines (MDA-MB-231 and CAL-51) in comparison with that in 2 non-aggressive luminal-type breast cancer cell lines (ZR-75-1 and MCF-7). miRNA expression in 2 highly aggressive TNBC cell lines (MDA-MB-231 and CAL-51) in comparison with that in 2 non-aggressive luminal-type breast cancer cell lines (ZR-75-1 and MCF-7)为明确微小RNA（miRNAs）在三阴性乳腺癌（TNBC）的肿瘤发生过程中的作用，本研究对2株高侵袭性三阴性乳腺癌细胞系（MDA-MB-231与CAL-51）及2株非侵袭性管腔型乳腺癌细胞系（ZR-75-1与MCF-7）的全基因组微小RNA表达谱进行了分析。 2株高侵袭性三阴性乳腺癌细胞系（MDA-MB-231与CAL-51）与2株非侵袭性管腔型乳腺癌细胞系（ZR-75-1与MCF-7）的微小RNA表达对比
