Expression data of PI5P4Kα/β knockdown cells
(shPI5P4Kα/β) or control vector cells (pLK0.1) using Affymetrix
Human Genome U133 Plus (~40,000 genes).
(A) Enrichment analysis of the curated pathways (BioCarta) following
PI5P4Kα/β knockdown. The p38 MAPK and RAS signaling pathways
were identified as the most significant pathways with respective p values of
1.83 × 10−4 and 0.004.
(B) Gene set enrichment analysis (GSEA) signatures highlighting
coordinated differential expression of gene sets that are enriched in
PI5P4Kα/β knockdown cells. The
CHARAFE_BREAST_CANCER_LUMINAL_VS_MESENCHYMAL_UP (genes upregulated in
luminal-like breast cancer cell lines compared to the mesenchymal-like ones) and
CHARAFE_BREAST_CANCER_LUMINAL_VS_BASAL_UP (genes upregulated in luminal-like
breast cancer cell lines compared to the basal-like ones) were scored among the
most significantly enriched gene signatures in PI5P4K knockdown cells, p
< 0.001.
