Open AccessMetallothionien 3 expression is frequently down-regulated in oesophageal squamous cell carcinoma by DNA methylation
Metallothionein 3 (MT3) inhibits growth in a variety of cell types. We measured MT3 gene expression by RT-PCR, and DNA methylation in the MT3 promoter by combined bisulphite restriction analysis, in four oesophag...
