Additional file 1: of microRNA-21 promotes breast cancer proliferation and metastasis by targeting LZTFL1

Figure S1. The expression level and survival analysis of miR-21 in breast cancer patients from TCGA database. A. The overall survival rates of breast cancer patients (n = 1061) with low or high expression levels of miR-21 were estimated with the Kaplan–Meier method by log-rank test according to data from the Cancer Genome Atlas (TCGA) on Kaplan–Meier Plotter platform (http://kmplot.com/analysis/). B. The relative miR-21 expression levels in normal breast tissue (n = 61) and invasive breast cancer tissue (n = 76) were analyzed according to data from TCGA provided by Oncomine (https://www.oncomine.org).
