KMT5C increases senescence-associated proliferation arrest in human cells (oncogene-induced senescence; elevated SUV420H2/H4K20me3).

KMT5C showed no clear effect on initiation of cellular senescence in human cells (SUV420H2 overexpression).
“Although elevated SUV420H2 upregulates H4K20me3, this does not accelerate senescence of primary human cells.”

MIR29A inhibits KMT5C in mouse cells (downstream of activated TGF-β signaling).
“both of which directly suppress their novel target, Suv4-20h, thus reducing H4K20me3 abundance in a Smad-dependent manner”
