Abstract: MicroRNAs are a class of small non-coding RNAs that perform a crucial function in posttranscriptional
gene regulation. Dysregulation of these microRNAs is associated with many types of
cancer progression. In tumorigenesis, downregulated microRNAs might function as a tumour suppressor
by repressing oncogenes, whereas overexpressed miRs might function as oncogenes by suppressing
tumour suppressor. Similarly, Metadherin (also known as AEG-1/ LYRIC), is an oncogene, the levels
of which are found to be very high in various cancers and play a crucial role in the proliferation of cells
and invasion. Our review focuses on the study, which shows the alteration of microRNA expression
profile and suppression of carcinogenesis when MTDH/AEG-1 is targeted. It summarises the studies
where downregulation and upregulation of AEG-1 and microRNAs, respectively, alter the biological
functions of the cell, such as proliferation and apoptosis. Studies have reported that AEG-1 can be
direct or indirect target of microRNA, which could provide a new-insight to know the underlying molecular
mechanism and might contribute to the progress of new therapeutic strategies for the disease.
