(A) Human breast tissue microarray (pilot TMA) was
immunostained with Slit2 antibody using IHC. Representative images showing Slit2
expression levels in normal (n=10), infiltrative ductal carcinoma (IDC) (n=50)
and lymph node-positive metastatic (LN+ metastatic) (n=40) breast tissues.
(B) The graph depicts the percentage of human breast
samples expressing different levels of Slit2.
(C) The expression level of Slit2 in human breast tissues
using UALCAN database. BL1, basal-like 1; BL2, basal-like 2; IM,
immunomodulatory; M, mesenchymal; MSL, mesenchymal stem-like; LAR, luminal
androgen receptor; UNS, unspecified.
(D) Analysis of Slit2 gene copy number in TCGA dataset
using Oncomine. N, normal breast (n-111); DC, ductal carcinoma (n-5); IDC &
ILC, invasive ductal and invasive lobular carcinoma (n-5); IDC & LC,
invasive ductal and lobular carcinoma (n-14); IDC, invasive ductal carcinoma
(n-639).
(E) Using experimental TMA, the association of Slit2
protein expression levels with patient survival was analyzed. The Kaplan-Meier
graph demonstrating the association of Slit2 expression level with patient
survival.
(F) Analysis of breast cancer patient overall survival
based on expression levels of Slit2 mRNA in the KM-plotter database
(n=1115).
(G) Analysis of breast cancer lymph node-positive (LN+)
metastases patient survival based on expression levels of Slit2 in the
KM-plotter database (n=936).
