Project description:All the reports on insect small RNAs come from holometabolous insects. However, small RNAs of hemimetabolous insects have not yet been investigated.Study of hemimetabolous insect small RNAs could provide more insights into evolution and function of small RNAs in hemi- and holometabolous insects. The locust is an important, economically harmful hemimetabolous insect and its phase changes is an interesting phenomenon.Here, we used high-throughput sequencing to characterize and compare the small RNA transcriptomes of gregarious and solitary phases in locusts. We found abundant small RNAs and their different expression profiles in the two phases. Small RNAs were sequenced from gregarious and solitary phases of Locusta migratoria,respectively.

Project description:Aposematism and warning coloration are common defense strategies used by animals to deter predators. Pestilential gregarious locusts display a striking black-brown pattern, which is presumed to be a form of warning coloration compared to green solitary locusts. However, the specific mechanisms involved in regulating this distinctive pattern are not yet understood. Here, we found that different amounts of β-carotene and β-carotene-binding protein (βCBP) complexes confer the black tergum and brown sternum of locust. The expression level of βCBP is regulated by the bZIP transcription factor ATF2, which is activated by protein kinase C alpha (PKCα) in response to crowding. Specifically, ATF2 is phosphorylated at Ser327 and translocates to the nucleus, where it binds to specific sites on the βCBP promoter and stimulates overexpression. Differential phosphorylation of ATF2 resulted in the divergent black and brown body coloration of gregarious locusts. The overexpression of βCBP in the sternum is essential for the accumulation of red pigments, which creates the sharp contrast between the black tergum and the brown sternum. This spatial variation in ATF2 phosphorylation levels allows locusts to adapt to changing environmental conditions and better evade predation.

Project description:We evaluated the expression profile of miRNA and snoRNA of normal mucosa in five patients with synchronous CRCs and seven patients with solitary CRCs using the Affymetrix GeneChip miRNA 1.0 array. We found that global dysregulated miRNAs and snoRNAs in normal mucosa between solitary and synchronous CRC. Our findings represent the first comprehensive miRNA and snoRNA expression signatures in normal mucosa between solitary and synchronous CRC, which increases the understanding of the molecular basis of synchronous CRC, and firstly implicates the difference of genetic background in patients with solitary and synchronous CRC.

Project description:In mammals, oocytes are formed in the female embryo and need to be preserved in the ovary to ensure the viability of the next generation. How oocytes are maintained for decades is unclear. Here, we combined pulse-chase stable isotope labelling coupled with mass spectrometry, single-cell RNA-seq, microscopy and NanoSims to create an atlas of protein homeostasis in mouse oocytes and ovaries over the entire reproductive lifespan. Our results show that protein turnover in the ovary is much slower than in other organs, with hundreds of extremely long-lived proteins across a broad range of complexes and pathways, including mitochondria, ribosomes and the cytoskeleton. We propose that slow protein turnover helps to maintain proteostasis in oocytes and the ovary over long periods, protecting the germline across generations.

Project description:We evaluated the profile of miRNA and snoRNA expression in 7 solitary CRC and matched normal colorectal tissues using the Affymetrix GeneChip miRNA 1.0 array. We found that global dysregulated miRNAs and snoRNAs between cancer tissue and normal mucosa in solitary CRC. Our findings firstly implicates that dysregulation of snoRNAs and miRNA may play important role in the cancinogenesis and present therapeutic targets for solitary CRC.

Project description:Desert locusts (Schistocerca gregaria) show an extreme form of phenotypic plasticity and can transform between a cryptic solitarious phase and a swarming gregarious phase. The two phases differ extensively in behavior, morphology and physiology but very little is known about the molecular basis of these differences. We used our recently generated Expressed Sequence Tag (EST) database derived from S. gregaria central nervous system (CNS) to design oligonucleotide microarrays and compare the expression of thousands of genes in the CNS of long-term gregarious and solitarious adult desert locusts. This identified 214 differentially expressed genes, of which 40% have been annotated to date. These include genes encoding proteins that are associated with CNS development and modeling, sensory perception, stress response and resistance, and fundamental cellular processes. Our microarray analysis has identified genes whose altered expression may enable locusts of either phase to deal with the different challenges they face. Genes for heat shock proteins and proteins which confer protection from infection were upregulated in gregarious locusts, which may allow them to respond to acute physiological challenges. By contrast the longer-lived solitarious locusts appear to be more strongly protected from the slowly accumulating effects of ageing by an upregulation of genes related to anti-oxidant systems, detoxification and anabolic renewal. Gregarious locusts also had a greater abundance of transcripts for proteins involved in sensory processing and in nervous system development and plasticity. Gregarious locusts live in a more complex sensory environment than solitarious locusts and may require a greater turnover of proteins involved in sensory transduction, and possibly greater neuronal plasticity. Two condition experiment: Solitarious central nervous system (CNS) vs gregarious CNS. 6 biological repeats per condition, balanced over 3 male and 3 females samples. The overall experimental design consisted of two identical repeats of an n+2 A-optimal design, organized per sex (n=6 per sex, 3 solitarious - 3 gregarious samples)
