I wanted to do experiments on miRNA and its regulatory effects on target oncogene.
miRNA Let7 family (7b in particular) has a negative regulatory effect on the KRAS gene. I want to prove this premise by transfection. Would it be efficient to use MCF-7 cells or MB 231? These are the cells lines we have readily available and I wanted some inputs from those who have had experience with these lines and the KRAS gene.
Thanks!
