Ferroptosis, an iron-dependent form of programmed cell death characterized by excessive lipid hydroperoxides accumulation, emerges as a promising target in cancer therapy. Among the solute carrier (SLC) superfamily, the cystine/glutamate transporter system antiporter components SLC3A2 and SLC7A11 are known to regulate ferroptosis by facilitating cystine import for ferroptosis inhibition. However, the contribution of additional SLC superfamily members to ferroptosis remains poorly understood. Her ...[more]

RNA-Seq of wild-type murine primary cortical neurons co-cultured in a transwell-based system with Mecp2 knock-out or wild-type cortical murine astrocytes

Project description:Rett syndrome (RTT; OMIM#312750) is a rare devastating neurodevelopmental disorder that represents the most common genetic cause of severe intellectual disability in girls. Mutations in the X-linked methyl-CpG-binding protein 2 (MECP2) gene have been reported in over 95% cases of classical forms of RTT. Although initial studies supported a role for MeCP2 exclusively in neurons, recent data indicate a function also in astrocytes, which emerged as critical players involved in RTT pathogenesis through non-cell autonomous effects. Indeed, Mecp2 knock-out (KO) astrocytes cannot properly support neuronal maturation of wilt-type (WT) neurons and our data demonstrated a detrimental effect also on synaptogenesis and synaptic maintainence. Nevertheless, the molecular mechanisms by which RTT astrocytes can impact on neuronal health remains unknown. In comparison to previous studies exploring the transcriptomic and proteomic profiles of KO astrocytes per se, we used an indirect strategy to unveil the molecular mechanisms responsible for their negative action on neurons. We thus analysed the molecular pathways deregulated in WT neurons cultivated under the influence of KO (n=8) versus WT (n=7) astrocytes, in a transwell-based co-culture system, that allows the exchange of paracrine signals preventing cell-to-cell contact. Astrocytes were seeded on transwell inserts and transferred on neurons at Div0; the co-cultures were maintained until Div14. WT cortical neurons cultivated alone were also included (n=5).

RNA-seq from control and macroH2A1-depleted IMR90 primary human lung fibroblasts

Project description:The histone variant macroH2A1 and the poly(ADP-ribose) polymerase PARP-1 both regulate gene transcription by modulating chromatin structure and function. Of the two macroH2A1 splice variants, macroH2A1.1 and macroH2A1.2, the former is often suppressed in cancer and has the unique ability to interact with poly(ADP-ribose). Using ChIP-seq in primary lung fibroblasts, we demonstrate that macroH2A1 is incorporated into either of two spatially and functionally distinct types of chromatin; the first is marked by H3 K27 trimethylation, while the second contains a set of nine histone acetylations. MacroH2A1-regulated genes are involved in cancer progression are specifically found in macroH2A1-containing acetylated chromatin. Through the recruitment of PARP-1, macroH2A1.1 promotes the acetylation of H2B K12 and K120 which plays a key role in the regulation of macroH2A1 target genes in primary cells. The macroH2A1/PARP-1 pathway regulating H2B K12 and K120 acetylation is disrupted in cancer cells, in part, explaining macroH2A1’s role in cancer suppression. Three biological replicates of RNA-seq from cells expressing shRNA directed against macroH2A1 or luciferase as a control

Store-operated Ca2+ entry in follicular T cells controls humoral immune responses and autoimmunity

Project description:T follicular helper (TFH) cells promote affinity maturation of B cells in germinal centers (GCs), whereas T follicular regulatory (TFR) cells limit GC reaction. Store-operated Ca2+ entry (SOCE) through Ca2+ release-activated Ca2+ (CRAC) channels mediated by STIM and ORAI proteins is a fundamental signaling pathway in T lymphocytes. Here we show that SOCE is required for the differentiation and function of both TFH and TFR cells. Conditional deletion of Stim1 and Stim2 genes in T cells or Treg cells results in spontaneous autoantibody production and humoral autoimmunity. Conversely, antibody-mediated immune responses following viral infection critically depend on SOCE in TFH cells. Mechanistically, STIM1 and STIM2 control early TFR and TFH cell differentiation through NFAT-mediated IRF4, BATF and Bcl-6 expression. SOCE plays a dual role in GC response by controlling TFH and TFR cell function, thus enabling protective B cell responses and preventing humoral autoimmunity. RNAseq analyses of WT and Stim1Stim2 DKO follicular T cells and non-follicular T cells; 4-6 mice per cohort in duplicates. Mice were infected for 10 days with LCMV.

A novel RAF kinase inhibitor with DFG-out binding mode: high efficacy in BRAF-mutant tumor xenograft models in the absence of normal tissue hyperproliferation

Project description:Purpose: Seek for differential gene expression in vemurafenib-resistant A375 tumors vs. untreated controls to provide a rationale for resistance mechanism Methods: mRNA profiles of vemurafenib-resistant A375 tumors and untreated control tumors were generated by transcriptome sequencing of A375 melanoma bearing mice. Since our xenograft samples contain a mixture of human and mouse RNAs we mapped RNASeq reads against a hybrid human/mouse genome. We than removed reads of potential mouse origin by taking only reads that map uniquely to human chromosomes. On average 23% of reads were removed as potential mouse reads. We than took the remaining reads (on average 77% per sample) to determine the gene expression levels for each sample. Normalized expression levels of 5 resistant samples were compared to 4 untreated control samples to detect differnetially regulated genes which may contribute to vemurfenib resistance Results: Expression levels of several genes were consistently altered in all resistant samples. Expression of e.g. genes encoding SPRY2, SPRY4, DUSP6, CCND1, PIK3R3, FGFR1, EPHA4, MCL1, and IGF1R was down-regulated, whereas expression of PDGFC, VEGFC, ABCB9 and KITLG was increased. Conclusions: Our study reports several differentially expressed genes which may contribute to vemurafenib resistance in A375 tumor bearing mice RNA sequencing of genes expressed in A375 tumors bearing mice treated with vemurafenib until in vivo resistance appeared vs. untreated A375 tumors

Proteomic analysis of primary graft dysfunction and high particle flow rate

Project description:Background: Primary graft dysfunction (PGD) remains a challenge to lung transplantation (LTx) recipients as a leading cause of poor early outcomes. New methods are needed for the rapid detection of PGD and the measurement of particle flow rate (PFR) from exhaled breath is a novel means to monitor disease. Methods: 22 recipient pigs underwent orthotopic left LTx and were evaluated for PGD on the third post-operative day. Exhaled breath particles (EBPs) and PFR were measured on mechanical ventilation. EBPs were evaluated with mass spectrometry and the proteome was compared to tissue biopsies and bronchoalveolar lavage fluid (BALF). Findings were confirmed in EBPs from 11 human transplant recipients. Results: 9 recipients developed PGD and had significantly higher PFR (686.4 (449.7-8824.0) particles per minute (ppm)) compared to recipients without PGD (116.6 (79.7-307.4) ppm, p=0.0005). From proteomic analysis, porcine and human EBP proteins recapitulated the BAL and adherens and tight junction proteins were underexpressed in PGD tissue. Conclusions: Histological and proteomic analysis found significant changes to the alveolar-capillary barrier to explain the increased PFR in recipients with PGD. Combined with the similarity of proteomic profiles between EBPs and BALF, exhaled breath measurement is proposed as a rapid and non-invasive bedside measurement of PGD.

RNA-seq melanoma

Project description:Using a chromatin regulator-focused shRNA library, we found that suppression of sex determining region Y-box 10 (SOX10) in melanoma causes resistance to BRAF and MEK inhibitors. To investigate how SOX10 loss leads to drug resistance, we performed transcriptome sequencing (RNAseq) of both parental A375 (Ctrl. PLKO) and A375-SOX10KD (shSOX10-1, shSOX10-2) cells. To ask directly whether SOX10 is involved indrug resistance in BRAF(V600E) melanoma patients, we isolated RNA from paired biopsies from melanoma patients (pre- and post- treatment) , that had gained BRAF or MEK inhibitor resistance . We performed RNAseq analysis to determine changes in transcriptome upon drug resistance. Investigate genes regulated by SOX10 and differntial gene expression between pre- and post-treatment biopsies. We use short hairpin RNA to suppression SOX10 in A375 cells and cells were harvested with trizol reagent for RNA isolation. For paired biopsies (patient samples) we collected the first biopsy before the initiation of treatment and the second biopsy after drug resistance developed. RNA was isolated from FFPE samples and subjected for RNA sequencing.
