Project description:Pea (Pisum. sativum L.) is a traditional and important edible legume that can be sorted into grain pea and vegetable pea according to their harvested maturely or not. Vegetable pea by eating the fresh seed is becoming more and more popular in recent years. These two type peas display huge variations of the taste and nutrition, but how seed development and nutrition accumulation of grain pea and vegetable pea and their differences at the molecular level remains poorly understood. To understand the genes and gene networks regulate seed development in grain pea and vegetable pea, high throughput RNA-Seq and bioinformatics analysis were used to compare the transcriptomes of vegetable pea and grain pea developing seed. RNA-Seq generated 18.7 G raw data, which was then de novo assembled into 77,273 unigenes with a mean length of 930 bp. Functional annotation of the unigenes was carried out using the nr, Swiss-Prot, COG, GO and KEGG databases. There were 459 and 801 genes showing differentially expressed between vegetable pea and grain pea at early and late seed maturation phases, respectively. Sugar and starch metabolism related genes were dramatically activated during pea seed development. The up-regulated of starch biosynthesis genes could explain the increment of starch content in grain pea then vegetable pea; while up-regulation of sugar metabolism related genes in vegetable pea then grain pea should participate in sugar accumulation and associated with the increase in sweetness of vegetable pea then grain pea. Furthermore, transcription factors were implicated in the seed development regulation in grain pea and vegetable pea. Thus, our results constitute a foundation in support of future efforts for understanding the underlying mechanism that control pea seed development and also serve as a valuable resource for improved pea breeding.

Project description:Sensitivity to cisplatin is increased in SKOV-3 cells after transfecting the cells with unphosphorylatable PEA-15 (PEA-15AA) but not in cells transfected with the empty vector and phosphomimetic PEA-15 (PEA-15DD). In order to investigate the regulation of the underlying genes that increased the sensitivity to cisplatin after transfection with PEA-15AA, a small and well-annotated Clariom S gene microarray was performed.

Project description:The present prospective study included a total number of 3 patients with a final diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH), who were treated by pulmonary endarterectomy (PEA) at the Kerckhoff Heart and Thorax Center between 2016 and 2020. Biopsies of the myocardial interventricular septum from 3 patients were collected at baseline (BL) before PEA surgery (pre-septal-PEA) In this case, to account for technical and safety aspects, the specimens were taken from the myocardial interventricular septum. The aim of the Study was a comparative characterization of RNA-profiles of septum in CTEPH patients after PEA surgery (postPEA) compared to before PEA surgery (pre-septal-PEA).

Project description:Bioinformatic prediction, deep sequencing of microRNA and expression analysis during phenotypic plasticity in the pea aphid acyrthosiphon pisum We developed high throughput Solexa sequencing and bioinformatic analyses of the genome of the pea aphid Acyrthosiphon pisum in order to identify the first miRNAs from a hemipteran insect. By combining these methods we identified 155 miRNAs including 56 conserved and 99 new miRNAs. Moreover, we investigated the regulation of these miRNAs in different alternative morphs of the pea aphid by analysing the expression of miRNAs across the switch of reproduction mode.

Project description:In angiosperms, the mature seed consists of an embryo (E), a seed coat (SC), and, in many cases, an endosperm. In contrast to knowledge about embryo and endosperm, we have relatively little knowledge of SC, especially at the genomics level. In this study, we analyzed the gene expression during seed development using the panel of cultivated and wild pea genotypes. We report the comprehensive gene expression changes related both to development as well as domestication status. Analysis of seed developmental stages revealed extensive modification of gene expression between wild pea progenitor and cultivated pea crop. A significant difference in gene expression dynamics appeared between early and late developmental stages D1, D2, and D3, D4, D5 in wild pea genotypes, where the expression was increased 3-5-fold and 5-10-fold, respectively. Our work extends knowledge about the role of the seed coat during pea seed development. We described gene expression dynamic resulting in specific metabolic profiles providing new insight into pea domestication.

Project description:Palmitoylethanolamide (PEA) is an endogenous lipid mediator with recognized immunomodulatory actions, yet its effects in skeletal muscle remain poorly defined. We investigated whether PEA influences myogenesis and profiled the acute transcriptomic response of differentiated C2C12 myotubes. Dose-tolerability assays identified reduced metabolic activity and viability at 100 µM PEA, so 10 µM was used for subsequent experiments. Across differentiation, PEA decreased myotube number (90.3 ± 10.6 vs 112.6 ± 10.1 in control) while increasing nuclear fusion index (37.8 ± 5.7% vs 30.7 ± 3.2%); myotube area was unchanged. In myoblasts, 24 h PEA exposure increased the proportion of cells in G0/G1 (48.2 ± 1.2% vs 42.3 ± 1.9%) with a concomitant reduction in S-phase (21.7 ± 1.2% vs 25.5 ± 1.2%), consistent with G1 arrest and reduced proliferative drive. RNA sequencing revealed a distinct transcriptional signature after 24 h PEA treatment, with 1,952 differentially expressed genes (1,028 upregulated; 924 downregulated, q < 0.05). Pathway-level changes encompassed cytokine–receptor interactions, chemokine, JAK–STAT, NF-κB, NOD-like and Toll-like receptor signalling. PEA downregulated NF-κB target/pro-inflammatory cytokine genes (Il1a, Il1b, Il12a, Il33, Tnfrsf19) while upregulating interferon-related and chemokine genes (e.g., Stat2, Oas1b, Gbp7, Cxcl14, Ccl5), indicating an anti-inflammatory/immune-priming profile. Notably, N-acylethanolamine acid amidase (Naaa), a lysosomal PEA hydrolase, was highly expressed and significantly induced, whereas fatty acid amide hydrolase (Faah) was low and unchanged, suggesting a muscle-specific bias toward NAAA-dependent PEA metabolism. Peroxisome proliferator-activated receptor-α (PPARα) was expressed at low levels and unaffected by PEA, indicating that the observed responses occur largely independent of canonical PPARα signalling. Together, these data show that PEA biases skeletal muscle toward a less proliferative but more fused and inflammation-resolving phenotype, accompanied by transcriptional reprogramming of immune pathways and preferential engagement of NAAA. While in vitro concentrations exceed reported plasma levels and mRNA changes may not fully predict protein/function, these findings provide the first comprehensive transcriptomic characterisation of PEA in myotubes and motivate in vivo studies to test whether PEA’s dual actions translate into benefits for muscle regeneration, adaptation, or anti-atrophy interventions.

Project description:To dissect the molecular mechanisms of PEA-15-mediated paclitaxel sensitization in ovarian cancer cells, we performed cDNA microarray analysis using SKOV3.ip1-S116A cells (Ser116 of PEA-15 substituted with alanine) and SKOV3.ip1-S116D cells (Ser116 of PEA-15 substituted with aspartic acid). cDNA microarray data analysis showed that SCLIP (SCG10-like protein), also known as STMN3, was highly expressed in SKOV3.ip1-S116D cells and was involved in pPEA-15-mediated paclitaxel sensitization in ovarian cancer cells.
