MicroRNAs (miRNAs) play vital roles in down-regulating gene expression at the post-transcriptional level. A set of 24 UV-B stress-responsive miRNAs (13 up-regulated and 11 down-regulated) was identified in Populus tremula plantlet by expression profiling with our in-house miRNA filter array. Six of the UV-B-responsive miRNA and their corresponding target(More)
MicroRNAs (miRNAs) are endogenous small RNAs of ~22 nucleotides (nt) that play a key role in down regulation of gene expression at the post-transcriptional level in plants and animals. Various studies have identified numerous miRNAs that were either up regulated or down regulated upon stress treatment. Here, we sought to understand the temporal regulation(More)
MicroRNAs (miRNAs) and other endogenous small RNAs act as sequence-specific regulators of the genome, transcriptome, and proteome in eukaryotes. The interrogation of small RNA functions requires an effective, widely applicable method to specifically block small RNA function. Here, we report the development of a highly effective technology that targets(More)
PURPOSE To evaluate variants in the LRPAP1, CTSH, LEPREL1, ZNF644, SLC39A5, and SCO2 genes in 298 unrelated patients with early-onset high myopia (eoHM). METHODS Genomic DNA from 298 patients with eoHM was analyzed by whole exome sequencing. Variants in LRPAP1, CTSH, LEPREL1, ZNF644, SLC39A5, and SCO2 genes were selected and analyzed with bioinformatics.(More)
Our work strongly suggests that microRNA858 regulates anthocyanin biosynthesis in tomato by modulating the expression of two R2R3 MYB transcription factors, underscoring the importance of microRNAs in the gene regulatory network controlling specialized metabolism in plants. The biological functions of microRNA858 (miR858), a recently identified small RNA,(More)
OBJECTIVE The goal of this study was to identify mutations in 25 known causative genes in 47 unrelated Chinese families with cone-rod dystrophy (CORD). METHODS Forty-seven probands from unrelated families with CORD were recruited. Genomic DNA prepared from leukocytes was analyzed by whole exome sequencing. Variants in the 25 genes were selected and then(More)
MicroRNAs (miRNAs), an endogenous type of small RNAs of approximately 22 nucleotides (nt), have long resided in the cells of plants and animals including humans, constituting an ancient pathway of gene regulation in eukaryotes. They have a simple structure in their mature form but carry enormous information that may regulate up to 90% of the human(More)
IMPORTANCE Mutations in CNGA3 are the most common cause of achromatopsia and cone-rod dystrophies. OBJECTIVE To identify CNGA3 mutations in patients with cone dystrophies or Leber congenital amaurosis. DESIGN, SETTING, AND PARTICIPANTS Clinical data and genomic DNA in 267 Chinese probands from 138 families with cone dystrophies and 129 families with(More)
PURPOSE The majority of Leber hereditary optic neuropathy (LHON) cases are caused by one of three mitochondrial DNA (mtDNA) primary mutations (m.3460G>A, m.11778G>A, and m.14484T>C). In recent studies, we and others have shown that mutation m.3635G>A is a primary LHON mutation, particularly in Chinese. The purpose of this study was to perform a thorough(More)
We report the molecular epidemiology of three primary mutations in mitochondrial DNA (mtDNA) responsible for Leber hereditary optic neuropathy (LHON) based on analysis of probands suspected with LHON from 903 Chinese families. Most of them had optic neuropathy of unknown cause, and only 128 had a family history of optic neuropathy. Mutations in the mtDNA(More)
