In higher plants, microRNA (miRNA) is involved in regulation of developmental processes, including sexual organ development. Seven novel miRNA families with one known miRNA were isolated by constructing a small RNA library from a mixture of anther from a cytoplasmic male sterile line and its maintainer. Two miRNAs are conserved in plant species. A total of(More)
We aim to investigate the preventive and therapeutic effects of ghrelin on a rat NAFLD model and possible underlying mechanism. Sprague-Dawley rats were fed with high-fat diet for 8 weeks to induce NAFLD. A group of rats were also treated with ghrelin throughout the NAFLD induction. After 8 weeks, rats were sacrificed for liver injury measurements. Rats(More)
The evolutionary history of plants in the southeast Tibetan Plateau might be the most complicated around the world because of the area's extremely complex topography and climate induced by strong tectonic activity in recent history. In this research, we implemented a phylogeographical study using chloroplast sequences (psbA-trnH and trnQ-rps16 intergenic(More)
In this study, we aimed to investigate the therapeutic effects and involved mechanisms of resveratrol on an established non-alcoholic fatty liver disease (NAFLD) murine model. Wild-type and autophagic mediator ULK1 heterozygous knockout mice were induced to have NAFLD by high-fat diet for 8weeks. After that, resveratrol treatment was applied with the(More)
Macrophage phagocytosis of tumor cells mediated by CD47-specific blocking antibodies has been proposed to be the major effector mechanism in xenograft models. Here, using syngeneic immunocompetent mouse tumor models, we reveal that the therapeutic effects of CD47 blockade depend on dendritic cell but not macrophage cross-priming of T cell responses. The(More)
Reversible methylation of histone tails serves as either a positive signal recognized by transcriptional assemblies or a negative signal that result in repression. Invading viral pathogens that depend upon the host cell's transcriptional apparatus are also subject to the regulatory impact of chromatin assembly and modifications. Here we show that infection(More)
Plant microRNAs (miRNAs) act as negative regulators of gene expression by slicing target transcripts or inhibiting translation. A number of miRNAs play important roles in development. In order to investigate the potential function of miRNAs during male gametogenesis in rice, we obtained both gene and small RNA expression profiles by combining microarray and(More)
The cellular transcriptional coactivator HCF-1 interacts with numerous transcription factors as well as other coactivators and is a component of multiple chromatin modulation complexes. The protein is essential for the expression of the immediate early genes of both herpes simplex virus (HSV) and varicella zoster virus and functions, in part, by coupling(More)
China contains some of the world's greatest diversity of Apiaceae (Umbelliferae), with ten endemic genera. Our previous investigation into the phylogenetic relationships of Chinese Apiaceae subfamily Apioideae, based exclusively on nrDNA ITS sequences, revealed several major clades heretofore unrecognized in the subfamily and confirmed the phylogenetic(More)
Reversible methylation of histone tails serves as either a positive signal recognized by transcriptional assemblies or a negative signal that result in repression1–4. Invading viral pathogens that depend upon the host cell’s transcriptional apparatus are also subject to the regulatory impact of chromatin assembly and modifications5–8. Here we show that(More)
