CNNM4 and breast cancer: According to the miRNA proxyhypothesis, previously postulated by the group of Mahal and co-workers,−,  these predict possible biological functions of CNNM4 and diseasesin which its regulation, and that of Mg2+, may be relevant.For example, phenotypic analysis identified mammary neoplasms, cancerousand benign, as phenotypes associated with a large number of genesalso targeted by the miRNAs that regulate CNNM4 (Figure S6B).
