We also found that the expression level of members of the two clusters, miR-520b and miR-302c, were negatively correlated with their targeted genes based on gene expression analysis We identified the expression patterns of miRNAs and gene transcripts in the undifferentiation of human embryonic stem cells; among the miRNAs that are highly expressed in undifferentiated embryonic stem cells, the miR-520 cluster may be closely involved in hES cell function and its relevance to chromatin structure warrants further study. [score:11]
To infer the function of these miRNAs, we predicted 2,436 targets for the miR-302 cluster and 4,691 targets for the miR-520 cluster by querying the public database miRNAMap 2.0, and 2,284 target genes were shared by both clusters suggesting functional similarity. [score:7]
Our results confirmed the recent report that majority of miRNA genes in hES cells were expressed from Chromosomes 19 and X [55] and demonstrated the significant upregulation of miR-520 cluster in hES cells. [score:6]
Among the hES signature miRNAs, the miR-520 cluster shared a similar expression pattern and seed sequence as the well known miR-302 family and targeted the same genes as the miR-302 family. [score:5]
Among the miRNAs upregulated in hES cells, we observed 7 miRNAs were located in the miR-302 cluster and 21 miRNAs were located in miR-520 cluster. [score:4]
The upregulation of miR-302 cluster and miR-520 cluster in hES cells suggests their ability to modulate local chromatin states which is necessary for stem cell pluripotency [58, 59]. [score:4]
In addition, we identified 21 hES upregulated miRNAs that were co-localized in a cluster on chromosome 19, the miR-520 cluster, many of which shared consensus seed sequence with miR-302 family and which can be used as candidate biomarkers for pluripotency (Additional file 1). [score:4]
Among these miRNAs, miR-518b, miR-518c, miR-519b, miR-519c, miR-520a, miR-520c, miR-520e, miR-520g, and miR-524* are over-expressed in undifferentiated hES cells [24, 26, 29]. [score:3]
Along with the reports of miR-302 family on chromosome 4 [16, 17, 19, 25, 26], several groups have reported the expression of members of miR-520 cluster on chromosome 19 in hES cells [24, 26, 29]. [score:3]
The miR-302 cluster and miR-520 cluster target large groups of genes which share overlapping functions based on Gene Ontology (GO) analysis. [score:3]
Gene Ontology (GO) enrichment analysis confirmed that the inferred functions of miRNAs within the miR-302 and miR-520 clusters were overlapping based on their involvement in cell growth, negative regulation of cellular metabolic process, negative regulation of transcription, and small GTPase mediated signal transduction. [score:3]
Especially, members of the miR-302 cluster on chromosome 4 and miR-520 cluster on chromosome 19 were highly expressed in undifferentiated hES cells. [score:3]
To visualize the functions of these miRNA targeted genes, a binary (red indicate participate in the functional category and green indicate not) heatmap was used to indicate functional commonality among all miRNAs in miR-302 and miR-520 clusters. [score:3]

Decreased expression of miR-342 in the therapeutically challenging triple -negative breast tumours, increased miR-342 expression in the luminal B tumours, and downregulated miR-520g in ER and PR -positive tumours indicates that not only is dysregulated miRNA expression a marker for poorer prognosis breast cancer, but that it could also present an attractive target for therapeutic intervention. [score:13]
The response graphs for miR-342, miR-520g and miR-520d* in relation to ER, PR and HER2/ neu status, respectively, are shown in Figure 4. Some miRNAs showed that with increased expression, the probability of receptor positivity increased; conversely, other miRNAs showed that with increased expression, the likelihood of the sample being classed as receptor -positive decreased. [score:5]
miR-520g shares sequence homology with miR-520h, and these miRNAs were coordinately expressed in our dataset (Figure 5); it is therefore probable that miR-520g may also be a regulator of ABCG2. [score:4]
There was a significant positive correlation between miR-520g microarray expression and RQ-PCR (R = 0.4, P = 0.029, Pearson). [score:3]
Importantly, miR-520g is computationally predicted to target a number of breast-cancer-related genes including ABCG2 (BCRP) [54]. [score:3]

In the cohort of 95 breast tumours with 17 matched tumour -associated normal breast tissue tissues there was no significant difference in miR-520g expression between tumour and tumour -associated normal breast tissue (P = 0.228, paired t test). [score:3]
The expression of miR-520g was also analysed using RQ-PCR. [score:3]
Furthermore, the expression patterns and phenotypic associations of the top-ranking miRNAs miR-342 and miR-520g were validated in an independent sample set of 95 tumours (Figure 7). [score:3]
MiR-342 and miR-520g expression was further analysed in 95 breast tumours. [score:3]
The miRNA signatures generated for ER status (miR-342, miR-299, miR-217, miR-190, miR-135b, miR-218), for PR status (miR-520g, miR-377, miR-527-518a, miR-520f-520c) and for HER2/ neu status (miR-520d, miR-181c, miR-302c, miR-376b, miR-30e) include miRNAs that have previously been identified as dysregulated in breast cancer and other cancers [7, 9, 37- 43] and involved in the regulation of cell functions such as growth, apoptosis, migration and invasion [38, 42, 43]. [score:3]
Notably, two chromosomal locations account for a number of the dysregulated miRNAs in these predictive sets: Ch19q13 (miR-520g, miR-520d, miR-527-528a, miR-520f-520c, miR-181c) and Ch14q32 (miR-342, miR-299, miR-377, miR-376b). [score:2]
Within the tumour samples, miR-520g expression was significantly higher in PR -negative breast tumours (n = 33) compared with PR -positive tumours (n = 58) (P = 0.032, independent t test). [score:2]
To our knowledge this is the first report of miR-520g dysregulation in association with ER and PR status in breast cancer. [score:2]
MiR-520g expression was elevated in ER and PR -negative tumours. [score:2]
The miR-520g expression was also significantly higher in ER -negative tumours (n = 32) compared with ER -positive tumours (n = 62) (P = 0.005, independent t test). [score:2]
Stepwise ANN analysis identified predictive miRNA signatures corresponding with oestrogen (miR-342, miR-299, miR-217, miR-190, miR-135b, miR-218), progesterone (miR-520g, miR-377, miR-527-518a, miR-520f-520c) and HER2/ neu (miR-520d, miR-181c, miR-302c, miR-376b, miR-30e) receptor status. [score:1]

However, construction of a Venn diagram showed that only 262 putative target genes are common between the miR-519 and miR-520 subfamilies in group I, indicating that the miR-519 and -520 subfamilies target different sets of genes. [score:5]
The group I miR-519 subfamily also shares 262 putative target genes with the miR-302/-372 families, far fewer than the miR-520 subfamily (Fig.   3a, red box). [score:3]
However, the miR-520 and miR-302/372 families share a significant number of target genes (Fig.   3a) suggesting common biological functions. [score:3]
The miRNA expression levels were determined as the absolute miRNA transcript copy number per cell, which ranged from 0 copy, at a real-time RT-PCR C [t] value ≥ 35 (see ), to 377,200 copies per cell at a C [t] value of 25.7 in miR-520g-3p in ESC H9 cells (Fig.   1b). [score:3]
The results showed that 1185 putative shared genes were obtained between the miR-520 and -302/372 families (Fig.   3a, blue box and Additional file 1: Table S1), suggesting that the miR-520 subfamily might share similar biological functions with the miR-302/372 family. [score:1]
Hence, it is highly likely that the group I miR-520 miRNAs may also contribute to reprogramming, as supported by the predicted involvement of miR-520 miRNAs in the reprogramming-related apoptosis and cell proliferation pathways (see Fig.   4 and below). [score:1]

In HepG2 cells, EGCG differentially represses the expression of five miRNAs (miR-30b*, miR-453, miR-520-e, miR-629, and miR-608) involved in inflammatory pathways, the peroxisome proliferators-activated receptors (PPAR) signaling pathway, the insulin signaling pathway, glycolysis and gluconeogenesis, oxidative phosphorylation, and glutathione metabolism [127].

Therefore, when we discuss the functions of miR-373 here, we should bear in mind that other members of miR-520/373 family may possess the same functions. [score:1]
miR-373 is one member of miR520/373 family, which consists of three different miRNA clusters possessing identical seed region, miR-302/367, miR-371/372/373 and miR-520 [8, 18, 22]. [score:1]
