1. LATS2-associated gene expression pattern is down-regulated specifically in lumB breast tumors.
LATS2-associated gene expression pattern is down-regulated specifically in lumB breast tumors. (A) Scatter plot of LATS1 and LATS2 expression levels in breast cancer tumors (TCGA-BRCA dataset). Pearson’s correlation coefficient A cutoff of the 20% of tumors expressing the lowest levels of each LATS gene was used to divide the tumors into three groups: LATS1L, LATS2L, and LATSL, compared with LATSH. (B) Heatmap depicting the expression levels of a 20-gene LATS2L signature (the 20 most down-regulated genes exclusively in LATS2L tumors, compared with LATSH tumors; see Table S4 and the Materials and Methods section) in breast tumors (TCGA-BRCA) sorted according to PAM50 subtype classification. (C) Distribution of LATS2 mRNA expression levels in different breast cancer subtypes (PAM50, TCGA-BRCA); ***P-value < 0.001, t test comparing lumB tumors with all other subtypes. Number of tumors of each subtype is indicated at the bottom. (D) Kaplan-Meier analysis of survival probability of luminal breast cancer patients (METABRIC dataset, n = 1139; Cox proportional hazards model) divided according to expression levels of the LATS2L signature (as in B).
