The data files support the figures, tables and supplementary files of the related publication.
Background:
N-Myc downstream-regulated gene 4 (NDRG4) is an intracellular protein that is predominantly expressed in the normal brain and heart. The related study investigates the role of NDRG4 expression in normal breast tissue and the relevant impact of DNA promoter hypermethylation in breast primary tumors and tumor cell lines, along with the potential of NDRG4 promoter hypermethylation as a mechanistic biomarker of breast cancer metastasis.
This approach represents a method for assessing risk of developing metastatic disease alternative to e.g. simple number of positive axillary lymph nodes in combination with clinicopathological factors. The molecular approach presented, using a multigene expression panel, involves analysis of a set of cancer-related genes.
Study design summary and sample sizes:
To explore the relationship between NDRG4 promoter methylation and expression levels and patient clinicopathological parameters and outcome, survival analysis for the NDRG4 promoter methylation was conducted in 782 patients dichotomized in higher and lower methylation groups by MethSurv. The correlation between the presence of NDRG4 methylation and well-established prognostic factors was also explored in an existing cohort of 61 patients with invasive breast ductal carcinoma from AC Camargo Cancer Center (ACC).
The methods includes microarray analysis of 64 genes - 11 of which were interrogated via MsigDB, and in silico expression and methylation analysis using paired normal and primary breast tumors obtained from The Cancer Genome Atlas (TCGA) through the MethHC database.
