Although expressed at lower levels than the highly abundant miR-30 family, two members of the miR-642 family were the most highly up-regulated miRNA in our adipogenesis mo del. [score:6]
The expression profile of the miRNAs that were strongly up-regulated during adipogenesis (miR-642a-3p, miR-378, miR-30a, miR-30b, miR-30c, miR-30d, miR-30e, and miR-193b) was validated by quantitative PCR (qPCR; Additional file 4). [score:6]
The expression patterns of miRNAs that were previously reported in adipocytes or their precursors are in agreement with published data, as summarized in Additional file 3. However, the adipogenesis -dependent regulation of many of the differentially expressed miRNAs we identified has never been described before; these include miR-642a-3p, miR-345, miR-193b, miR-29c, miR-664, miR-10b, miR-136, miR-22*, miR-181a, miR-154*, let-7a, let-7b and let-7c. [score:6]
This is consistent with an up-regulation of miR-642a, assuming that miR-642a and GIPR share the same promoter. [score:4]
Of interest, in a recent study identifying the association of miR-519b with human obesity, Martinelli and co-workers [31] also detected that miR-642a was up-regulated in 19 out of 20 fat depots of obese subjects. [score:4]
Up-regulation of miR-642a-3p, miR-378/378* and miR-30 miRNAs suggests their contribution to adipogenesis. [score:4]
In our data, no reads corresponding to miR-642a were detected for undifferentiated cells, indicating highly adipogenic-restricted expression. [score:3]
In particular, for miRNAs with highly tissue-specific expression, such as miR-642a, the low numbers of reads backing the mirBase entries might lead to incorrect annotations. [score:3]
For identification of differentially expressed miRNAs, only miR-642a-3p reached significance since the cloning frequency of miR-642a-5p was under the threshold of 0.03% that we defined. [score:3]
miR-642a-3p, with a 7.32-fold induction during adipogenic differentiation, was the most highly and significantly (P-value = 4.67.10 [-7]) regulated miRNA in our dataset (Table 1 and Figure 2a). [score:2]
We identified several annotated, but also previously unknown, small RNAs that are regulated during adipogenesis, such as miR-642a-3p. [score:2]
Altogether, these data suggest that miR-642a might be linked to adipose tissue development. [score:2]
The current mirBase release (release 17) includes two miR-642 entries: miR-642a (miR-642a-5p), which was detected at one copy in a unique, high-throughput sequencing experiment; and miR-642b, which is backed by an unknown number of reads. [score:1]
We also verified the quality of miR-642a-3p sequencing. [score:1]
This approach revealed the un-annotated miR-642a-3p as a highly adipocyte-specific miRNA. [score:1]
Light grey shading highlights miR-642-5p (bases in orange) and miR-642-3p (bases in blue). [score:1]
Figure S6 in Additional file 9 shows that the positions allowing discrimination of miR-642-3p from miR-642b correspond to high quality values. [score:1]
In our dataset, both miR-642a-5p and-3p were induced during differentiation, but miR-642a-3p had a higher relative abundance than miR-642a-5p (Figure 3). [score:1]
Genome-browser representation of reads matching (a) miR-642a and (b) miR-378. [score:1]
While we also detected miR-642b, this sequence was much less (14-fold) abundant than miR-642a-3p. [score:1]
Yet, until recently (September 2010), only miR-642a-5p was present in mirBase release 15 (named miR-642 in release 15) and, thus, detectable on commercial microarrays. [score:1]
Of note, miR-642a-3p is not annotated in mirBase 16; only miR-642a-5p has been reported before. [score:1]
Table S4: miR-642 raw read numbers. [score:1]
As shown in Additional file 8, miR-642b is, in fact, located on the opposite strand to miR-642a. [score:1]
These values suggest that the corresponding reads were correctly assigned to miR-642-3p. [score:1]
miR-642a-3p and miR-642b sequences are, in fact, quite similar and only diverge by one base in their 3' end. [score:1]

Interestingly, both miR-642a-3p and miR-642a-5p were undetectable in undifferentiated hMADS cells, suggesting a high specificity for adipocytes. [score:1]
Bases that allow discrimination between miR-642-3p and miR-642b are highlighted in blue and indicated by arrows. [score:1]
Amongst both miR-642a isoforms, only miR-642a-3p was above the 0.03% threshold in our mo del. [score:1]
To support this hypothesis, we counted the reads attributed to each miR-642 species within the raw read files. [score:1]
miR-642a is positioned on chromosome 19, in intron 7 of the GIPR (glucose -dependent insulinotropic polypeptide receptor) gene (Additional file 5). [score:1]
In our dataset, the few reads that were attributed to miR-642b could, in fact, correspond to miR-642a-3p reads bearing sequencing errors. [score:1]

Overall, 18 miRNAs were differentially expressed; 5 miRNAs were found up-regulated in the group of patients that are in complete remission when compared to the relapsed or the control groups; miR-3681 (A), miR-601 (B), miR-642a (C), miR-136 (D) and miR-26b (E). [score:5]
Specifically, 2 miRNAs; miR-720a and miR-891a were down-regulated and 6 miRNAs; miR320e, miR-3681, miR-601, miR-642a, miR-136 and miR-26b were overexpressed in the patient cohort when compared to the control group. [score:5]
The expression profiles initially obtained for miR-320e and miR-642a were not validated with meta-analyses. [score:3]
In addition, the oncogenic properties initially detected for miR-642a and miR-320e were not confirmed with meta-analyses suggesting tumor suppressor activities. [score:3]
Following meta-analysis, miR-122, miR-3162 and miR-642a were found to be significantly different between RE and CR samples in the log [2], ratio transformed expression values. [score:3]
Based on the current findings, 8 miRNAs; miR-3681, miR-601, miR-320e, miR-34a, miR-642a, miR-136, miR-26b and miR-192 were found overexpressed in the patient group. [score:3]
In particular, miR-3681 (A), miR-642a (B), miR-26b (C), miR-136 (D) and miR-320e (E) were increased in alive samples as well as manifested linear regression with respect to expression moving from alive samples to controls. [score:3]
Of note, the oncogenic property of miR-642a as detected following the initial analysis, was not confirmed by meta-analysis (Table  1). [score:1]
MiR-3162 and miR-642a were also found to be significantly different in associations between RE and CR samples. [score:1]
In total, 8 miRNAs were associated with patients’ clinical outcome; miR-3681, miR-601, miR-320e, miR-642a, miR-720, miR-891a, miR-136 and miR-26. [score:1]

For comprehensiveness, it should also be noted that analysis of the data for gender -driven differences showed that there is a significantly higher expression of hsa-miR-10b and hsa-miR-642 in males compared to females. [score:2]
This analysis included miR-184, miR-548a-5p, miR-574-3p, miR-616, miR-1233, miR-642, miR-140-3p, miR-517b, miR-10b and miR-380-3p (Figure  3, Tables  3 and 4 and Additional file 3: Table S3). [score:1]
Based on the analysis of hsa-miR-642, the population of 100 healthy subjects clearly can be separated in 2 groups, one with relatively high levels of hsa-miR-642 and one with low or undetectable levels of hsa-miR-642. [score:1]
As it has been shown that hsa-miR-642 is an adipocyte-specific miRNA, it will be of interest to see whether this hsa-miR-642 based clustering is linked to specific metabolic parameters, such as Body Mass Index or blood cholesterol and fatty acids levels, or insulin resistance [38]. [score:1]

Indeed, although CTNNA2 can be regulated by primate-specific miRNAs common to both monkeys and humans (miR-513a-3p, miR-518a-5p, miR-548a-5p, miR-576-5p, miR-586, miR-607, miR-625, miR-642), a number of miRNAs present in Homo sapiens but not in Macaca mulatta (miR-1208, miR-1247, miR-1290, miR-1324, miR-1825, miR-613 and miR-634) also target CTNNA2 [19], [29].
