Oncogenic HRAS suppresses clusterin expression through promoter hypermethylation
Silencing of gene expression by methylation of CpG islands in regulatory elements is frequently observed in cancer. However, an influence of the most common oncogenic signalling pathways onto DNA methylation has not yet been investigated thoroughly. To address this issue, we identified genes suppres...

description | Silencing of gene expression by methylation of CpG islands in regulatory elements is frequently observed in cancer. However, an influence of the most common oncogenic signalling pathways onto DNA methylation has not yet been investigated thoroughly. To address this issue, we identified genes suppressed in
HRAS
-transformed rat fibroblasts but upregulated after treatment with the demethylating agent 5-Aza-2-deoxycytidine and with the MEK1,2 inhibitor U0126. Analysis of gene expression by microarray and Northern blot analysis revealed the MEK/ERK target genes
clusterin
, matrix metalloproteinase 2 (
Mmp2
), peptidylpropyl isomerase C-associated protein
, syndecan 4, Timp2
and
Thbs1
to be repressed in the
HRAS
-transformed FE-8 cells in a MEK/ERK- and methylation-dependent manner. Hypermethylation of putative regulatory elements in
HRAS
-transformed cells as compared to immortalized fibroblasts was detected within a CpG island 14.5 kb upstream of
clusterin
, within the
clusterin
promoter and within a CpG island of the
Mmp2
promoter by bisulphite sequencing. Furthermore, hypermethylation of the
clusterin
promoter was observed 10 days after induction of HRAS in immortalized rat fibroblasts and a clear correlation between reduced
clusterin
expression and hypermethlyation could also be observed in distinct rat tissues. These results suggest that silencing of individual genes by DNA methylation is controlled by oncogenic signalling pathways, yet the mechanisms responsible for initial target gene suppression are variable. |
