Differential response to herbivory by Helicoverpa armigera in Cajanus cajan and Cajanus platycarpus

ABSTRACT: In synchrony with deciphering the transcriptomic basis of pod borer resistance in C. platycarpus, the aim of the present work was to corroborate and understand how the leaf proteome in these two contrasting cajanus species explain the differential responses to herbivory. To the best of our knowledge this is the first investigative analysis applying proteomics to understand plant herbivore interactions in cajanus species. The study is one of the best approaches to assess cellular alterations from a multi-level perception and to enhance our understanding of resistance traits in the wild relatives.

The pigeonpea wild relative Cajanus platycarpus is resistant to Helicoverpa armigera, one of the major pests responsible for yield losses in Cajanus cajan. Deciphering the molecular mechanism underlying host plant resistance is pertinent to identify proteins that aid in the mitigation of the insect pest. The present study adopted comparative proteomics as a tool to interpret the resistance mechanism(s) in C. platycarpus vis-à-vis C. cajan during continued herbivory (up to 96 h).

The transcriptome of TRPV1-positive sensory neurons revealed by subgroup-elimination transcriptomics

Project description:We developed an approach to rapidly eliminate the subgroup of sensory neurons expressing the heat-gated cation channel TRPV1 from dissociated rat sensory ganglia using agonist treatment followed by density centrifugation. To identify transcripts predomintly expressed in TRPV1-positive neurons, we compared the transcriptome of all cells within sensory ganglia versus all cells without TRPV1 expressing neurons using RNA-Seq. Four replicate experiments with RNA from DRG neurons of one rat per experiment were performed. Dissociated neurons were split up in three parts, treated with solvent DMSO (0.1%), casaicin (10 µM), or RTX (100 nM) for 30 min followed by gradient centrifugation. RNA was extracted from the remaining pellet containing either all cells or all cells without TRPV1-positive neurons.

Transcriptional characterization of maize roots in response to urea and nitrate

Project description:Although urea is the most used nitrogen fertilizer worldwide, little is known on the capacity of crop plants to use urea per se as a nitrogen source for development and growth. To date, the molecular and physiological bases of its transport have been investigated only in a limited number of species. In particular, up to date only one study reported the transcriptomic modulation induced by urea treatment in the model plant Arabidopsis (MM-CM-)rigout et al., 2008 doi: 10.1104/pp.108.119339). In maize, one of crops using huge amount of urea, only a physiological characterization of uptake and assimilation of the N-source has been conducted. General aim of the present work was the comprehension of the molecular basis of urea uptake and assimilation in maize plants, using a transcriptomic approach. In addition, the work focused on the possible interactions between the two main N-sources, conceivably occurring concomitantly in the soil, urea and nitrate. 5 dd-old maize plants were treated for 8 hours with nutrient solution containing nitrogen in form of urea; nitrate; urea and nitrate; or not exposed to any form of nitrogen. Three different biological replicates were used for each sample repeating the experiment three times. All samples were obtained pooling roots of six plants.

Distinct lactation-associated macrophages exist in murine mammary tissue and human milk

Project description:Macrophages are involved in immune defense, organogenesis and tissue homeostasis. They also contribute to the different phases of mammary gland remodeling during development, pregnancy and involution post-lactation. Yet, less is known about the dynamics of mammary gland macrophages in the lactation stage. Here, we describe a macrophage population present during lactation in mice. By multi-parameter flow cytometry and single-cell RNA sequencing we reveal this population as distinct from the two resident macrophage subsets present pregestationally. These lactation-induced macrophages (LiMacs) are predominantly monocyte-derived and expand by proliferation in situ concomitant with nursing. LiMacs develop independently of IL-34 but require CSF-1 signaling and are partly microbiota-dependent. Locally, they reside adjacent to the basal cells of the alveoli and extravasate into the milk. Moreover, we also found several macrophage subsets in human milk, resembling LiMacs. Collectively, these findings reveal the emergence of unique macrophages in the mammary gland and milk during lactation.

Chromatin immunoprecipitation of human HNF3b and E2F4, and mouse NeuroD1, for THEME analysis

Project description:Genome-wide chromatin-immunoprecipitation (ChIP-chip) detects binding of transcriptional regulators to DNA in vivo at low resolution. Motif discovery algorithms can be used to discover sequence patterns in the bound regions that may be recognized by the immunoprecipitated protein. However, the discovered motifs often do not agree with the binding specificity of the protein, when it is known. RESULTS: We present a powerful approach to analyzing ChIP-chip data, called THEME, that tests hypotheses concerning the sequence specificity of a protein. Hypotheses are refined using constrained local optimization. Cross-validation provides a principled standard for selecting the optimal weighting of the hypothesis and the ChIP-chip data and for choosing the best refined hypothesis. We demonstrate how to derive hypotheses for proteins from 36 domain families. Using THEME together with these hypotheses, we analyze ChIP-chip datasets for 14 human and mouse proteins. In all the cases the identified motifs are consistent with the published data with regard to the binding specificity of the proteins.

CUT&RUN experiment in colon cancer cells (HCT116, DLD1 and SW620), assessing TBX3 genomic occupancy

Project description:The Wnt/β-catenin signaling pathway plays crucial roles in nearly all parts of embryonic development and adult stem cell homeostasis. Its aberrant activation has been linked to many diseases such as developmental irregularities and various severe forms of cancer, with colorectal cancer (CRC) as a prime example. While much work has been dedicated to uncovering effective therapeutics to block oncogenic Wnt signaling, such interventions have not proven trivial because of the broad activity of Wnt throughout the adult body and the difficulty in finding suitable molecular targets. We have previously identified the developmental transcription factor TBX3 as a participant of the Wnt-mediated transcriptional regulation. Here we examine the genome-wide binding pattern of TBX3 in the human CRC cells lines HCT116 (25 replicates), DLD1 (2 replicates) and SW620 (2 replicates), by employing CUT&RUN (C&R) with Low-Volume and Urea (LoV-U; Zambanini et al., 2022).

Bottlenose Dolphin Plasma Proteome

Project description:This study was designed to characterize and evaluate the proteome in plasma samples collected before and after a public swim interaction involving four male (2 to 6 y) aquarium-based bottlenose dolphins (Tursiops truncatus). Blood samples were collected from the tail flukes appoximately 15 min before (n=4 samples) and 15 min after (n=4 samples) the first swim interaction of the day, which was reinforced by a regularly scheduled feeding regimen. Samples were subjected to liquid chromatography-tandem mass spectrometry (LC-MS/MS) as well as conventional clinical biochemistry analysis. Mass spectra data were used to search the NCBI database restricted to Tursiops truncatus which resulted in the identification of 196 unique proteins with a broad range of functional roles based on manual GO analysis. Differential regulation of proteins was based on log2 mean fold change (FC) and statistical probability such that the abundance of lysozyme (FC -1.2036; P<0.058) an immune-related protein and flavin reductase (FC -0.9702; P<0.004) a metabolic-related protein were highest before compared to after the swim interaction. Both proteins decreased by 58 and 52%, respectively.

Chronic fluoxetine treatment of socially isolated rats modulates prefrontal cortex proteome

Project description:Chronic social isolation (CSIS) is a risk factor for human major depressive disorder (MDD). Fluoxetine (Flx) is an antidepressant commonly used for first-line MDD therapy. However, its downstream mechanisms of action, beyond serotonergic signaling, remain elusive. We aimed to analyze the effects of CSIS followed by chronic Flx treatment on proteome changes in the adult male rat prefrontal cortex (PFC) cytosolic and non-synaptic mitochondria (NSM)-enriched fractions. Treatment with Flx ameliorated depression-like behaviors in CSIS-induced rat model of depression as assessed by sucrose preference test and forced swim test. Proteomic data showed that Flx increased the expression of proteins involved in cytoskeleton and regulation of intracellular Ca2+ homeostasis in the cytosol and of enzymes linking the glycolytic pathway to the citric acid cycle (Dlat) and ATPase-coupled ion transmembrane transport in NSM. CSIS resulted in down-regulation of cytosolic proteins involved in proteasome/ubiquitination processes and glutathione antioxidative system and up-regulated expression of key enzymes participating in oxidative phosphorylation. Presence of cytochrome c in the cytosol indicated compromised mitochondrial membrane integrity. Flx treatment in CSIS rats showed predominately an upregulation of vesicle-mediated transport proteins and reduced Uqcrfs1 along with transport in NSM, favoring reduced energy metabolism. Our data suggest that proteins from both cytosol and NSM-enriched fractions are affected by Flx in a key brain region associated with stress response, cognitive process and regulation of emotion.
