HULC interactome MS analysis

ABSTRACT: we report a high throughput strategy to screen for lncRNA interacting proteins in vivo by combining tobramycin affinity purification and mass spectrometric analysis (TOBAP-MS). This method was applied to establish the interactome network for the lncRNA highly-upregulated in liver cancer (HULC).

Interacting with proteins is a crucial way for long noncoding RNAs (lncRNAs) to exert their biological responses. Here we report a high throughput strategy to characterize lncRNA interacting proteins in vivo by combining tobramycin affinity purification and mass spectrometric analysis (TOBAP-MS). Using this method, we identify 140 candidate binding proteins for lncRNA highly upregulated in liver cancer (HULC). Intriguingly, HULC directly binds to two glycolytic enzymes, lactate dehydrogenase A ( ...[more]

lncRNA MALAT1 interactome - Quantitative proteomics reveals that long non-coding RNA MALAT1 interacts with DBC1 to regulate p53 acetylation

Project description:Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a long non-coding RNA (lncRNA) that was first discovered as a prognostic marker for lung cancer metastasis. MALAT1 has been implicated in the tumorigenesis of numerous tumor types. To further delineate the underlying molecular mechanism, we established a high-throughput strategy to characterize the interacting proteins of MALAT1 by combining RNA pull down, quantitative proteomics, bioinformatics analysis, and experimental validation.

Transcription profiling of planktonic pseudomonas aeruginosa exposed to tobramycin treatment

Project description:As a comparison to tobramycin-treated P. aeruginosa biofilms, we investigated the response of planktonic P. aeruginosa to tobramycin by microarray. Experiment Overall Design: We included 2 control (untreated) cultures and 2 tobramycin-treated cultures. We used mid-exponential phase cultures of P. aeruginosa PA14. Replicate cultures were incubated in the presence or absence of 5 Î¼g/mL tobramycin for 30 minutes at 37Â°C.

Identification of lncRNA-NTT regulated genes using small interference RNA knockdown for cDNA microarray

Project description:We used microarrays to detail the global programme of gene expression underlying lncRNA-NTT knockdown We employed small interference RNA (siRNA) and microarray techniques to investigate the effect of NTT silencing on gene expression in HepG2 cells. HepG2 cells were transfected with NTT siRNA (siNTT) or control siRNA (siCon) for 120 h, and then RNA extraction and cDNA synthesis for hybridization on Affymetrix microarrays. We collect siRNA-transfection HepG2 cells and test knockdown efficiency. After comparison of the siCon group then we choose the best three sample for microarray.

Determine changes of lncRNAs expression in malignant hepatocytes

Project description:We performed a hybridization-based microarray analysis for lncRNA expression to understand the involvement of lncRNAs in HCC and to investigate differentially expressed lncRNAs in HCC, thereby characterizing their potential roles in tumor growth. The expression profiles of SMMC7721 HepG2 and Huh7 human HCC cell lines and the HL-7702 human immortalized normal hepatocyte cells were performed by the lncRNA microassay. SMMC7721, HepG2 and Huh7 human HCC cell lines were defined as the experimental group and HL-7702 cell line was used as the control.

Expression study of the Hodgkin’s lymphoma cell line L-1236 upon CRISPR Cas9-mediated knockout of lymphotoxin alpha (LTA) compared to control

Project description:Persistent activation of canonical and non-canonical NF-κB pathways is a hallmark of the malignant Hodgkin and Reed-Sternberg cells in classical Hodgkin lymphoma (cHL). We identified lymphotoxin alpha (LTA), which is secreted by the cHL cell line L-1236 in high concentrations. This cytokine contributes to the constitutive activation of the canonical and non-canonical NF-κB pathways. L-1236 cells were purchased from the DSMZ (Braunschweig, Germany) and cultured in RPMI (Gibco) with 10% heat-inactivated fetal calf serum (FCS; Gibco). Cells were transducted with the lentiCRIPSPR v2 vector containing gRNAs which target the second (g2) and the fourth exon (g3) of LTA. Following single cell clonal selection, L-1236 control cells (v2) and two LTA knockout (KO) clones g2_1 and g3_4 were cultured in normal culture medium for 72 h. The RNA was extracted using the RNeasy kit (Qiagen) according to manufacturer’s instructions. Preparation of cDNA, fragmentation and labeling was performed with the GeneChIPTM WT PLUS reagent kit (ThermoFisher Scientific). Samples were hybridized to the human Clariom™ S Assay (ThermoFisher Scientific).

Transcription profiling of P. aeruginosa biofilms treated with tobramycin grown on CFBE41o- cells

Project description:We grew Pseudomonas aeruginosa biofilms on CFBE41o- human airway cells in culture, and we treated these biofilms with tobramycin. Microarray analysis was performed to gain an understanding of the global transcriptional changes that occur during antibiotic treatment. Experiment Overall Design: We compared three untreated control samples with three tobramycin-treated samples. Biofilms were grown on CFBE41o- cells in culture for 9 hours in MEM/0.4% arginine. Replicate samples were then incubated in the presence or absence of 500 Î¼g/mL tobramycin for 30 minutes.

Elucidation of the mechanism behind the potentiating activity of baicalin against Burkholderia cepacia complex biofilms

Project description:Burkholderia cenocepacia J2315 biofilms were described to have an increased susceptibility towards tobramycin when baicalin hydrate was added to the treatment. The goal of this transcriptomic analysis is to elucidate the effect of baicalin hydrate on gene expression levels when added to tobramycin treatment. Therefore, biofilms were grown for 24 hours and treated for another 24 hours with either tobramycin (TOB) (1024ug/ml), baicalin hydrate (BH) (250uM) or a combination of both. Also, an untreated control (physiological saline) was included. This experiment was repeated twice, so three biological replicates per treatment were included for RNAsequencing.

RNA sequencing of Pseudomonas aeruginosa phoenix colonies, viable but non-culturable colonies (VBNCs), and control samples

Project description:We report RNA sequencing data for mRNA transcripts obtained from tobramycin exposed phoenix colonies, VBNCs, and various controls (untreated lawn, edge of the zone of clearance of tobramycin, treated outer background lawn). Extracted mRNA was sequenced using an Illumina HiSeq 4000, mapped to a Pseudomonas aeruginosa PAO1 reference genome, and processed to obtain counts for all gene transcripts for each sample. This is the first sequencing data generated for Pseudomonas aeruginosa phoenix colonies and VBNCs.
