Pgr5 suppressor screen uncovers a distinct mechanism safeguarding the cytochrome b6f complex from damage through PGR5

ABSTRACT: PROTON GRADIENT5 (PGR5) is thought to promote cyclic electron flow (CEF) and its deficiency causes increased photosensitivity of photosystem I (PSI), leading to lethality under fluctuating light (FL). By screening for suppressor mutations that rescue FL lethality of pgr5 plants, we identified a portfolio of mutations affecting 12 photosynthesis-related proteins. Here we performed a proteomic analysis to compare a mutant lacking PGR5 vs wildtype ( at2g04360-1/pfsc1-1 vs. Col-0)

Gene expression Profiling in Follicular Lymphomas

Project description:Follicular lymphoma (FL) is an indolent, but incurable subtype of non-Hodgkin lymphoma. These tumor harbor t (14;18) translocation in at least 90% of patients. Recently, activating EZH2 mutations have been Follicular lymphoma (FL) is an indolent, but incurable subtype of non-Hodgkin lymphoma. These tumor harbor t (14;18) translocation in at least 90% of patients. Recently, activating EZH2 mutations have been found in a significant number of patients with FL. Gene expression profiling (GEP) was performed to determine differential gene-expression between the EZH2 mutated vs unmutated subgroups in FL. Total RNA extracted from fresh frozen specimens with FL diagnosis were processed for hybridization to Affymetrix HG-U133 plus 2 arrays. To enhance the identification of differential gene expression in FL tumor cells only, FL cases with a high B-cell content (enriched B-cell signature of >2-fold above the mean of the B-cell signature (pan B-cell markers) in the entire FL data set) were chosen for analysis.

Comparison of thymic mTEC cells from MyD88fl/fl x Foxn1Cre and MyD88fl/fl mice by transcription profiling

Project description:We compared in vitro mTECs-high from MyD88fl/fl x Foxn1Cre and MyD88fl/fl mice: Thymi were enzymaticaly digested, cells were MACS enriched for CD45- fraction, and FACS sorted using BD Influx sorter. mTECs-high were gated as EpCAM+CD11c-Ly51-MHCII+CD80+. Total RNA was isolated using RNeasy Plus Micro Kit (Qiagen). 5 samples per condition were used.

Analysis of the coding exome of follicular lymphoma

Project description:Follicular lymphoma (FL) constitutes the second most common non-Hodgkin lymphoma in the Western world. FL carries characteristic recurrent structural genomic aberrations. However, information regarding the coding genome in FL is still evolving. Here, we describe the results of massively parallel exome sequencing and high-resolution SNP 6.0 array profiling of 12 highly purified FL cases and validation of mutations in an expansion cohort of 45 cases. In addition to confirming high-frequency mutations in MLL2, CREBBP and BCL2, we report identification of 18 recurrently mutated genes in FL. These include novel mutations in MCL1, IRF8 and POU2FA/OCT2, and high-frequency mutations in various components of the linker histone HIST1H1. Further, multiple novel mutated genes located within regions of acquired uniparental disomy (aUPD) are identified, providing candidate genes for this common lesion type in FL. In aggregate, these data substantially broaden our understanding of the types and frequency of recurrently mutated genes and pathways in FL Twelve paired normal and tumor follicular lymphoma cases were profiled by SNP array for this study. However, in addition the data from 125 CEL files derived from the DNA of flow-sorted CD3+ cells from 125 CLL patients (122 CEL files from GSE30777) were used to firmly establish a normal copy number baseline for the dChip software to compute all subsequent normal and tumor DNA copy number values.

Functional relationship of GUN1 and FUG1 in plastid proteostasis

Project description:We have previously identified the chloroplast translation initiation factor IF-2, or FUG1, as a GUN1 interactor based on co-immunoprecipitation and co-expression analysis (Tadini et al., 2016). To further investigate the functional relationship between these two proteins, the double mutant gun1-103 fug1-3 was generated by crossing the single gun1-103 knock-out mutant and the fug1-3 knock-down mutant. We performed comparative proteomics on gun1-103 and fug1-3, as well as on the double mutant gun1-103 fug1-3.

HIC2 regulates maturation of the cardiovascular system

Project description:HIC2 is required for normal development of the heart. Loss of function mutants exhibit early embryonic lethality while heterozygous mutants have a partially penetrant ventricular septal defect. The aim of this study was to understand the function of HIC2 in early heart development by identifying potential transcriptional targets. We harvested whole hearts (which contain circulating erythrocytes) at embryonic day E9.5 and compared expression in a conditional loss of function mutant (Mesp1 Cre/+; Hic2 Fl/Fl) to controls (Hic2 Fl/Fl).

siRNA smart pool silencing of master regulators of Follicular Lymphoma transformation to DLBCL

Project description:Follicular lymphoma (FL) is the most common indolent subtype of non-Hodgkinâs lymphoma, with relatively long overall survival rate ranging from 6 to 10 years from time of diagnosis. However, 20-60% of FL patients undergo transformation to aggressive diffuse large B cell lymphoma (DLBCL), with a reduced median survival of about 1.2 years. The specific functional and genetic determinants of FL transformation are still elusive and only a relatively small fraction of the cases is accounted for by established, recurrent alterations in TP53, MYC and BCL6, inactivation of CDKN2A and CDKN2B, or amplification of REL. We addressed this deficiency by performing systematic analysis of a B cell specific regulatory model with FL transformation signatures, using the Master Regulator Inference algorithm (MARINa). We show that the candidate master regulators inferred by the algorithm in FL induce synthetic lethality in DLBCL cells and lead to identification of specific compound combinations inducing synergistic loss of viability in transformed DLBCL cells RNA was obtained from 45 samples, which included siRNA silencing of 5 single transcription factors, 5 combinations of two transcription factors and non-target control in triplicates.

Abberant Cathepsin S Activity Modulates the Immune Microenvironment in Follicular Lymphoma

Project description:Tumor cells can induce their own advantageous microenvironment. Here, we describe aberrant cathepsin S (CTSS) activity to modulate T-cell activation in follicular lymphoma (FL). In donor-derived FLs following bone marrow transplantation, we identified independent acquisition of CTSS mutations at Y132 in the donor´s and recipient's tumors. In a larger cohort, 6% of FL (20/312) harbored CTSS mutations, mostly Y132D, another 14% had CTSS amplification (40/280). Y132D leads to accelerated conversion from pro-CTSS to active CTSS and increased substrate cleavage, including CD74, which regulates MHC-II restricted antigen-presentation. In co-culture experiments, CTSS mutant lymphoma cells induced increased antigen-specific CD4+ T-cell activation. Moreover, antigen-processing was the top upregulated pathway in CTSS mutant primary FL biopsies. Thus, aberrant CTSS activity is a promising target in lymphoma.

A novel CRISPR-engineered prostate cancer cell line defines the AR-V transcriptome and identifies PARP inhibitor sensitivities.

Project description:Development of a novel CRISPR-derived cell line which is a derivative of CWR22Rv1 cells, called CWR22Rv1-AR-EK, that has lost expression of FL-AR, but retains all endogenous AR-Vs. AR-Vs act unhindered by loss of FL-AR to drive cell growth and expression of androgenic genes. Global transcriptomics demonstrate that AR-Vs drive expression of a cohort of DNA damage response genes and depletion of AR-Vs sensitizes cells to ionizing radiation.
