Scientists identify microRNA involved in cancer onset and metastasis
Scientists identify microRNA involved in cancer onset and metastasis (July 5, 2013 - Insidermedicine) From Massachusetts - A new report published in Cell identifies a microRNA highly involved in both cancer onset and metastasis. Researchers studied a mouse model, finding that microRNA-22 (miR-22) triggers genetic rewiring--in turn repressing the expression of genes and other microRNAs. In turn, miR-22 silences a family of enzymes that also act as tumour suppressors. This process led to the onset of breast and blood cancer in the rodents. Overexpression of miR-22 resulted in metastasis of the breast cancer to the lungs
