Opa interacting protein 5 (OIP5) has been reported to be over-expressed in several kinds of human cancer. However, the biological function and clinical significance of OIP5 in human breast cancer remains unknown. In this study, we found that OIP5 was notably over-expressed in breast cancer tissues compared with their corresponding nontumorous tissues. Statistical analysis showed a significant correlation...
SHC SH2-binding protein 1, a member of Src homolog and collagen homolog (Shc) family, has been recently identified in different contexts in unbiased screening assays. It has been reported to be over-expressed in several malignant cancers.Immunohistochemistry of SHCBP1 on 128 breast cancer tissues and adjacent normal tissues were used to evaluate the prognostic significance of SHCBP1. Survival analyses...
SNaPshot minisequencing is a rapid and robust methodology based on a single base extension with a labeled ddNTP. The present study detected 15 selected SNPs in the mitochondrial DNA (mtDNA) control and coding regions by minisequencing methodology using SNaPshot for forensic purpose. The samples were collected from 99 unrelated individuals of the Yi ethnic minority group in Yunnan Province. We have...
Roche 454 next-generation sequencing was applied to obtain extensive information about the transcriptomes of the bread wheat cultivar Yunong 201 and its EMS mutant line Yunong 3114. Totals of 1.43 million and 1.44 million raw reads were generated, 14,432, 17,845 and 27,867 isotigs were constructed using the reads in Yunong 201, Yunong 3114 and their combination, respectively. Moreover, 29,042, 34,722,...
Next generation sequencing technology has identified a series of miRNA variants (named “isomiRs”), which might be associated with cancer progression. We provide a new strategy to reanalyze the miR-seq datasets through a view of the isomiR spectrum. Firstly, differentially expressed (DE) isomiRs were detected with the DESeq algorithm based on negative binomial distribution. Secondly, the rank-based...
Adiponectin exerts anti-atherosclerosis property through its 2 receptors (AdipoR1 and AdipoR2). The mechanism regulating the expression of adiponectin receptors is unclear. Bioinformatics analysis showed that miR-221 targeted the 3′-untranslated region (3′UTR) of the AdipoR1 mRNA. The protein level and the mRNA level of AdipoR1 were reduced when miR-221 was expressed in human umbilical vein endothelial...
microRNAs (miRNAs) are a class of small non-coding RNAs that deregulate and/or decrease the expression of target messenger RNAs (mRNAs), which specifically contribute to complex diseases. In our study, we reanalyzed an integrated data to promote classification performance by rebuilding miRNA–mRNA modules, in which a group of deregulated miRNAs cooperatively regulated a group of significant mRNAs....
Accumulating evidence suggests that a single microRNA (miRNA) locus can generate a series of sequences during miRNA maturation process. These multiple sequences, called miRNA variants, or isomiRs, have different lengths and different 5′ and 3′ ends. Some of these isomiRs are detected as varied nucleotides and 3′ additional non-template nucleotides. As physiological miRNA isoforms, they have drawn...
Ribosomal protein s15a (RPS15A) is a highly conserved protein that promotes mRNA/ribosome interactions early in translation. Recent evidence showed that RPS15A could stimulate growth in yeast, plant and human lung carcinoma. Here we report that RPS15A knockdown could inhibit hepatic cancer cell growth in vitro. When transduced with shRPS15A-containing lentivirus, we observed inhibited cell proliferation...
Many microRNAs (miRNAs) are clustered on chromosomes and co-transcribed as polycistronic transcripts. Here, an integrated evolutionary analysis of human miRNA gene clusters and families was performed. Generally, miRNA gene clusters include 2–8 members, but some larger clusters have been found to have more members (over 40 miRNAs). 62.22% of them have been shown to be involved in homologous miRNA genes,...
A mature miRNA may be generated from 5p or 3p arm of a hairpin precursor. The selection may be flexible via “arm switching”. However, accumulating evidences suggest that both arms of many pre-miRNAs can yield mature functional miRNAs. Herein, we attempted to compare the isomiR expression profiles between the two arms through analyzing in-house and published small RNA deep sequencing datasets. Although...
We report a molecular cytogenetic characterization of 17p13.3 deletion syndrome by array comparative genomic hybridization (aCGH), fluorescence in situ hybridization (FISH) and quantitative polymerase chain reaction (qPCR) in a fetus with lissencephaly, corpus callosum dysgenesis, ventriculomegaly, microcephaly, intrauterine growth restriction (IUGR), polyhydramnios and single umbilical artery. aCGH...
We present prenatal diagnosis and array comparative genomic hybridization characterization of 3q26.31–q29 duplication and 9q34.3 microdeletion in a fetus with omphalocele, ventricular septal defect, increased nuchal translucency, abnormal first-trimester maternal screening and facial dysmorphism with distinct features of the 3q duplication syndrome and Kleefstra syndrome. The 26.61-Mb duplication...
We present prenatal diagnosis and molecular cytogenetic characterization of de novo mosaic r(13). A 32-year-old woman underwent amniocentesis at 18weeks of gestation because of maternal anxiety. Amniocentesis revealed a karyotype of 46,XY,r(13)[33]/45,XY,-13[19]. aCGH on uncultured amniocytes at repeated amniocentesis detected a 4.22-Mb deletion at 13q34. Interphase FISH on 100 uncultured amniocytes...
We present prenatal diagnosis and molecular cytogenetic analysis of mosaic small supernumerary marker chromosome 1 [sSMC(1)]. We review the literature of sSMC(1) at amniocentesis and chromosome 1p21.1-p12 duplication syndrome. We discuss the genotype–phenotype correlation of the involved genes of ALX3, RBM15, NTNG1, SLC25A24, GPSM2, TBX15 and NOTCH2 in this case.
MicroRNAs (miRNAs) are crucial negative regulators of gene expression at the post-transcriptional level. Next-generation sequencing technologies have identified a series of miRNA variants (named isomiRs). In this study, paralogous isomiR assemblies (from the miRNA locus) were systematically analyzed based on data acquired from deep sequencing data sets. Evolutionary analysis of paralogous (members...
