microRNA Expression Helps Drive
Cancer Initiation and Progression1
microRNAs (miRNA) are Master Regulators of Protein Synthesis and Cellular Function
- miRNAs are an important class of small RNAs that target and bind to messenger RNA (mRNA), regulating gene expression (protein synthesis)2
- More than 50% of human mRNAs may be influenced by miRNA-mediated regulation and are associated with several human cancers1
- By modulating protein synthesis, miRNAs regulate cellular processes such as survival, proliferation, migration, and death3

miRNAs Assessed by ThyraMIR® Can Help Rule in all Types of Thyroid Cancers4,5
