These findings indicate that microRNA-30a may act as a tumor suppressor in colorectal cancer and that microRNA-30a represses cell migration and invasion by decreasing metadherin, highlighting the therapeutic potential of microRNA-30a and metadherin in colorectal cancer treatment.
We identified miR-30a as a tumor-suppressive microRNA that targets HP1γ in vitro and in vivo to specifically suppress the growth of colorectal cancer in mouse xenograft models.
MicroRNAs (miRNAs) are dysregulated in many types of malignant diseases, including colorectal cancer. miRNA 30a (miR-30a) is a member of the miR-30 family and has been implicated in many types of cancers.
In conclusion, our data identified miR-30a-5p as a tumor-suppressing miRNA in colon cancer cells exerting its function via modulation of DTL expression, which is frequently overexpressed in colorectal cancer.
