Synthesis of 3D flower-like ZnO/ZnCoO composites with the heterogeneous interface for excellent electromagnetic wave absorption properties.

Reasonable structure and composition are essential for electromagnetic wave absorption (EMW). Herein, ZnO hollow spheres were prepared with carbon spheres as templates and then synthesized ZnO/ZnCoO composites by the solvothermal method and annealing treatment. The flower-like ZnCoO material was produced by self-assembly of ZnCoO nanosheets.

Overexpression of lncRNA NEAT1 mitigates multidrug resistance by inhibiting ABCG2 in leukemia.

Leukemia is a heterogeneous clonal disorder in which early hematopoietic cells fail to differentiate and do not undergo programmed cell death or apoptosis. Less than one-third of adult patients with leukemia are managed using current therapies due to the emergence of multidrug resistance (MDR), emphasizing the need for newer and more robust approaches. Recent reports have suggested that long non-coding RNAs (lncRNAs) contribute to selective gene expression and, hence, could be manipulated effectively to halt the progression of cancer.

Long Noncoding RNA MHRT Protects Cardiomyocytes against H2O2-Induced Apoptosis.

Acute myocardial infarction (AMI) remains a leading cause of morbidity and mortality worldwide. The exploration of new biomarkers with high sensitivity and specificity for early diagnosis of AMI therefore becomes one of the primary task. In the current study, we aim to detect whether there is any heart specific long noncoding RNA (lncRNA) releasing into the circulation during AMI, and explore its function in the neonatal rat cardiac myocytes injury induced by H2O2.

Horizontal gene transfer in plants.

Horizontal gene transfer (HGT) describes the transmission of genetic material across species boundaries. HGT often occurs in microbic and eukaryotic genomes. However, the pathways by which HGTs occur in multicellular eukaryotes, especially in plants, are not well understood.

Revisiting an important component of plant genomes: microsatellites.

Microsatellites are some of the most highly variable repetitive DNA tracts in genomes. Few studies focus on whether the characteristic instability of microsatellites is linked to phenotypic effects in plants. We summarise recent data to investigate how microsatellite variations affect gene expression and hence phenotype.

Characterization and functional annotation of nested transposable elements in eukaryotic genomes.

The movement of transposable elements (TE) in eukaryotic genomes can often result in the occurrence of nested TEs (the insertion of TEs into pre-existing TEs). We performed a general TE assessment using available databases to detect nested TEs and analyze their characteristics and putative functions in eukaryote genomes. A total of 802 TEs were found to be inserted into 690 host TEs from a total number of 11,329 TEs.

Characterization of transcriptional activation and inserted-into-gene preference of various transposable elements in the Brassica species.

Transposable elements (TEs) have attracted increasing attention because of their tremendous contributions to genome reorganization and gene variation through dramatic proliferation and excision via transposition. However, less known are the transcriptional activation of various TEs and the characteristics of TE insertion into genomes at the genome-wide level. In the present study, we focused on TE genes for transposition and gene disruption by insertion of TEs in expression sequences of Brassica, to investigate the transcriptional activation of TEs, the biased insertion of TEs into genes, and their salient characteristics.

Large-scale development of functional markers in Brassica species.

Numerous quantitative trait loci (QTL) have been detected in Brassica species, but fine-mapping of major QTL has advanced slowly. The development of functional markers can overcome this barrier. We used publicly available PlantGDB-assembled unique transcripts (PUTs) from Brassica species to design 7836 functional simple sequence repeat (SSR) primer pairs.

Characterization and comparison of gene-based simple sequence repeats across Brassica species.

Simple sequence repeats (SSRs) are important components of eukaryotic genomes and may play an important role in regulating gene expression. However, the characteristics of genic SSRs and the effect of interspecific hybridization and polyploidization on genic SSRs seem not to have received desired attention in terms of scientific investigations. To determine the features of genic SSRs and elucidate their role in polyploidization process of the Brassica family, we identified SSRs in Plant Genome Database-assembled unique transcripts (PUTs) of Brassica species.
