miR-191 Down-Regulation Plays a Role in Thyroid Follicular Tumors through CDK6 Targeting

Context: Well-differentiated thyroid carcinomas include papillary (PTC) and follicular (FTC) carcinomas. FTC is usually a more aggressive form of cancer than the more common papillary type. miR-191 expression is frequently altered in several neoplasias, being up-regulated in some cases, such as pancreatic carcinomas, and down-regulated in other carcinomas, such as melanomas.
