CD44 and gastric cancer: Albeit this proposed model can describe the potentialmechanism of action by which rs8193 allele C can imposeits oncogenic effect in gastric cancer, in vitro CD44 3 ́UTR luciferase assay with two alleles T and C and inthe presence and absence of miR-570 mimic, is stronglyrecommended in order to validate the ability of miR-570 to differentially target CD44 mRNA.
