Figure 1.

Hierarchical clustering centered on the median and visualization of the expression of significantly deregulated miRNAs in BC cell lines from young women. Heatmap representing the expression of 155 miRNAs that were significantly deregulated in breast cancer cell lines from young women. The expression is shown in different intensities, green below the median, red above and black unchanged with respect to the median. Cell lines are represented in pink for women younger than 35 years old and older women are indicated in purple. Molecular subtypes are indicated as triple negative (yellow) and luminal (blue).

TNBC: triple negative breast cancer; Lum: luminal; CLO: breast cancer cell lines from women older than 45 years old; CLVY: breast cancer cell lines from very young women (< 35 years old).
