Characteristics
miR-17-92 cluster, which comprises seven miRNAs and resides in intron 3 of the C13orf25 gene at 13q31.3 [1].
Cellular Localization
The mir-17–92 polycistron,is located in a region of DNA that is amplified in human B-cell lymphomas.
Function
Gene (MIR17HG), which is involved in the development, progression, and aggressiveness of colorectal cancer [2].
This polycistronic gene, called MIR17HG or Oncomir-1 because of its mainly oncogenic functions (ie, activities that enhance cell proliferation, inhibit apoptosis, and modulate angiogenesis), is related to the homologous MIR106a–363 cluster on chromosome X and the MIR106b–25 cluster on chromosome 7.8,9.[3] [4].
Regulation
Finding of preferential overexpression of the miR-17-92 cluster in lung cancers with small-cell lung cancer histology, a subtype of lung cancer with prominent neuroendocrine feature, warrants study on its regulation and potential involvement from the cell differentiation point of view [1].
Diseases
- colorectal cancer
- lung cancer
Expression
Expression levels of the six MIR17HG cluster members (miR-17, miR-18a, miR-19a, miR-19b-1, miR-20a,and miR-92a-1) were also quantified by RT-qPCR in 34 cases for which RNA was available. In particular, the expression of all six miRs was detected in 23 of 34 cases. miR-19b-1 and miR-92a-1 showed the highest expression level, while miR-18a showed the lowest [2].
Tumours resulting from combined c-myc and mir-17–19b expression consistently invaded visceral organs outside the lymphoid compartment, including liver, lung and occasionally kidney [5].
