MicroRNAs as Targets of Dietary Phytochemicals in Obesity and Cancer

MicroRNAs (miRNAs) are minute regulatory single stranded noncoding molecules (about 22 nucleotides) of ribonucleic acids that influence expression of gene all the way through posttranscription. They are known to control different biological processes for example differentiation of cell, survival, development, migration, their dysregulation and death of cells. There are excess of over 500 miRNAs with different roles in the human body. In this chapter, effort was made to discuss the potential roles of miRNA in obesity and cancer and how dietary phytochemicals modulate them.
