KLF5 and breast cancer: Similarly, LINC00393 achieved significant correlation with the transcription factor krueppel-like factor 5 (KLF5; r = 0.45; Fig 3B), whose high expression in basal-like breast cancers [25] was supported by both UBCS (log2FC = 2.18, p = 6.52E-05) and TCGA (log2FC = 1.73, p = 1.07E-30) datasets.
