Bulk RNAseq of control and 5TGM1 myeloma-bearing bone marrow T, NK, and non-hematopoietic stromal cells from C57Bl/6 mice

Project description:We hypothesized that the immune microenvironment of the bone marrow influences the progression of myeloma outgrowth in the 5TGM1 transfer model of multiple myeloma. Therefore we sorted bone marrow T, NK, and non-hematopoietic stromal cells from control and tumor-bearing C57Bl/6 mice.

RNA-seq on hematopoietic stem cells sorted from mice 1 month after they were irradiated (2Gy total body irradiation = IR) or not (non irradiated = NIR)

Project description:We aim at understanding how ionizing radiations (IR) increase the risk of developing myeloid leukemia. We recently showed that IR leads to the derepression of retroelements. Retroelements are major contributors of gene regulatory networks. However, the impact of retroelements derepression on the HSC transcriptome and function remains to be addressed. We hypothesized that retroelements derepression is involved in HSC transcriptomic alterations. To answer this question, we performed RNA-seq experiments in hematopoietic stem cells sorted from mice one month after they were irradiated and compared them to controls hematopoietic stem cells sorted from non-irradiated mice.

RNAseq of barley leaf and roots exposed to control and drought stress conditions

Project description:In this study, we used transcriptomic and hormonomic approaches to examine drought-induced changes in barley roots and leaves and its rhizosphere. By studying hormonal responses, alternative splicing events in barley, and changes in the rhizosphere microbiome, we aimed to provide a comprehensive view of barley drought-adaptive mechanisms and potential plant-microbe interactions under drought stress. This approach improved our understanding of barley adaptive strategies and highlighted the importance of considering plant-microbe interactions in the context of climate change.

RNA-seq GLV6 overexpression during lateral root initiation in Arabidopsis thaliana

Project description:The goal of this experiment was to identify the downstream targets of the GOLVEN6 peptide signaling pathway in Arabidopsis thaliana, specifically during lateral root initiation. Using an estradiol inducible GLV6 overexpression construct in wildtype and rgi1rgi5 double mutant (mutant in receptors for the GLV6 peptide) backgrounds, in combination with gravistimulation induced lateral root formation, the RGI receptor dependent transcriptional effects of GLV6 overexpression were characterized. An estradiol inducible GLV6 overexpression line in a wildtype (iGLV6) and in an rgi1rgi5 double receptor mutant background (rgi1rgi5/iGLV6) were used. 4-day old seedlings of both lines were gravistimulated (vertically grown seedlings were turned counterclockwise by 90°) to induce lateral root initiation in the resulting root bends. 8h after gravistimulation, seedlings of both lines were treated with 2µM of estradiol to induce GLV6 overexpression, or DMSO as a mock treatment. 3h and 6h after treatment, root bends were dissected and collected for RNA-sequencing. This yielded a total of 8 samples per replicate; 3h mock treated iGLV6 (IM3), 3h estradiol treated iGLV6 (IE3), 3h mock treated rgi1rgi5/iGLV6 (RM3), 3h estradiol treated rgi1rgi5/iGLV6 (RE3), 6h mock treated iGLV6 (IM6), 6h estradiol treated iGLV6 (IE6), 6h mock treated rgi1rgi5/iGLV6 (RM6), 6h estradiol treated rgi1rgi5/iGLV6 (RE6). For each sample, 4 replicates were obtained. This setup enabled the comparison of the GLV6 induced transcriptional effects between wildtype and rgi1rgi5 mutants at 2 time points after treatment, in samples that are strongly enriched for lateral root initiation events.

RNA sequencing of the non-hematopoietic microenvironment of aspirates from Multiple Myeloma patients at diagnosis and after treatment versus non-cancer controls

Project description:By generating a paired single cell RNA-sequencing database of the tumor niche from 10 newly diagnosed MM patients, we created a unique dataset allowing the in-depth analyses of stromal-immune interactions within the tumor microenvironment (see related accession number). Using this database, we identified the presence of inflammatory stromal fibroblasts in the bone marrow of Myeloma patients.The stromal inflammation was associated with NF-κB signaling, and sources of IL-1β or TNFα were specific immune subsets previously shown to be altered in MM, suggesting the presence of an immune cell-mediated feed-forward loop of bone marrow inflammation in MM. By tracking inflammatory signatures over time in individual patients undergoing first-line treatment using bulk RNA sequencing, we show that bone marrow inflammation is not reverted by successful anti-tumor therapy (this dataset), suggesting a role for stromal fibroblasts and bone marrow inflammation in disease persistence or relapse. Raw sequencing data files will be deposited to EGA.

Identity of root peridermis cells undergoing suberization in Arabidopsis

Project description:In order to unravel the molecular processes involved in the nature of the root peridermis tissue, as well as in the suberin biosynthesis pathways occurring in this tissue, we have made use of Translating Ribosome Affinity Purification (TRAP) followed by RNA sequencing (TRAP-SEQ) on two marker lines; pUBQ10::BLRP-FLAG-GFP-RPL18 and pGPAT5::BLRP-FLAG-GFP-RPL18 line, after dissection of a zone of the root comprised between the root-hypocotyl junction and the first lateral root, allowing the respective selection of RNAs originating from all cells of the root segment, or only from those peridermis cells expressing the GPAT5 marker and therefore undergoing suberization.

Targeting the MAtrix REgulating MOtif, MAREMO, abolishes hallmarks of cancer

Project description:Tumor targeted therapies have been largely inefficient due to lack of concomitant effects on the tumor microenvironment (TME). We investigated the MAtrix REgulating MOtif (MAREMO) mimicking peptide MP5, that inhibits the pro-tumorigenic extracellular matrix (ECM) molecule tenascin-C, using immunocompetent autologous breast cancer bearing mice. MP5 treatment led to tumor regression and reduced tumor cell dissemination. Several cancer hallmarks were abolished such as tumor cell promoting growth suppression and inhibition of plasticity enhancing responsiveness to death inducers. MP5 acts on other TME players leading to blood vessel normalization and depletion of fibroblasts diminishing the ECM as an orchestrator of immune suppression, causing immune cell infiltration and reactivation of anti-tumor immunity involving IFNgamma. Thus, targeting the tumor matrix using MAREMO in tenascin-C represents a powerful novel anti-cancer strategy.

Platelets favor the outgrowth of established metastases

Project description:Despite abundant evidence demonstrating that platelets foster metastasis, anti- platelet agents have low therapeutic potential due to the risk of hemorrhages. In addition, whether platelets can regulate metastasis at the late stages of the disease remains unknown. In this study, we subjected syngeneic models of metastasis to various thrombocytopenic regimes to show that platelets provide a biphasic contribution to metastasis. While potent intravascular binding of platelets to tumor cells efficiently promotes metastasis, platelets further support the outgrowth of established metastases via immune suppression. Genetic depletion and pharmacological targeting of the platelet-specific receptor GPVI in humanized mouse models efficiently reduced the growth of established metastases, independently of active platelet binding to tumor cells in the bloodstream. Our study is the first to demonstrate therapeutic efficacy when targeting animals bearing growing metastases. It further identifies GPVI as the first molecular target whose inhibition can impair metastasis without inducing collateral hemostatic perturbations.
