“…Although these reports predicted that the MMP-2 target genes in U2OS cells would be downregulated following depletion of MMP-2 and H3NT proteolysis, there were only slightly more MMP-2 target genes that were downregulated (57%) than upregulated (43%). Interestingly, these findings were consistent with other reports where the proportions of differentially expressed genes in melanoma cells and lymphoma-derived monocytes following depletion of H3NT proteolysis were strikingly similar, with 57% of genes downregulated and 43% upregulated [ 19 , 32 ]. These collective findings suggest that the establishment of H3NT proteolysis at lineage-specifying genes is necessary for their activation and proficient terminal differentiation, whereas H3NT proteolysis plays a minor role in the maintenance of target gene expression in proliferating cancer cells.…”

“…Under MMP-2 inhibition, there is minimal, or a lack of, histone H3 cleavage, and this results in a reduction in transcription, as well as cell proliferation [ 27 ]. Another study also found that MMP-9 (Gelatinase-B, closely related to MMP-2) is able to clip histone H3 and regulate gene expression involved in melanoma formation [ 132 ]. These studies further support MMP-2’s involvement in the epigenetic regulation of gene transcription within not only the nucleolus, but moreover, the nucleus.…”

“…We also found that nucleolar MMP-2 activity regulates RNA transcription through the clipping of histone H3, as H3 cleavage is associated with increased ribosomal RNA transcription and minimal or absence of H3 cleavage, when MMP-2 is inhibited, results in reduction in transcription, as well as cell proliferation [87]. Another study also found that MMP-9 (Gelatinase-B, closely related to MMP-2) is able to clip histone H3 and regulates genes expression involved in melanoma formation [88]. These studies further support MMP-2's involvement in epigenetics regulation of genes transcription within not only the nucleolus, but more, the nucleus.…”
