Transcription profiling time series of human bone marrow samples stored at room temperature for up to 48 hours after aspiration

ABSTRACT: Impact of pre-analytical handling on Bone Marrow (BM) mRNA Gene Expression: We have investigated the impact of RNA extraction protocols and time delays (24 and 48h) between sample aspiration and RNA extraction on RNA quality and gene expression profiles. Intact RNA can be extracted from BM samples stored at room temperature for up to 48h after aspiration. However, storage of BM has dramatic effects on mRNA expression of individual transcripts.

Large clinical trials on leukaemia, require the transport of bone marrow (BM) from participating clinics to central diagnostic laboratories. We have investigated the impact of RNA extraction protocols and time delays between sample aspiration and RNA extraction on RNA quality and gene expression profiles. Intact RNA can be extracted from BM samples stored at room temperature for up to 48 h. Gene expression analyses using Affymetrix U95Av2 GeneChips and a custom-designed cDNA array in parallel sh ...[more]

Comparative transcriptomic characterisation of canine prostate fine-needle-aspiration and tissue samples - from sampling to sequencing

Project description:Ultrasound-guided fine-needle aspiration (US-FNA) biopsy is a widely used minimally invasive sampling procedure for cytological diagnosis. This study investigates the feasibility of using US-FNA samples for both cytological diagnosis and whole transcriptome RNA-sequencing analysis (RNA-Seq), with the ultimate aim of improving canine prostate cancer management. The feasibility of the US-FNA procedure was evaluated intra vitam on 43 dogs. Additionally, aspirates from 31 euthanised dogs were collected for standardising the procedure. Each aspirate was separated into two subsamples: for cytology and RNA extraction. Additional prostate tissue samples served as control for RNA quantity and quality evaluation, and differential expression analysis. The US-FNA sampling procedure was feasible in 95% of dogs. RNA isolation of US-FNA samples was successfully performed using phenol-chloroform extraction. The extracted RNA of 56% of a subset of US-FNA samples met the quality requirements for RNA-seq. Expression analysis revealed that only 153 genes were exclusively differentially expressed between non-malignant US-FNAs and tissues. Moreover, only 36 differentially expressed genes were associated with the US-FNA sampling technique and unrelated to the diagnosis. Furthermore, the gene expression profiles clearly distinguished between non-malignant and malignant samples. This proves US-FNA to be useful for molecular profiling.

Inhalation and oropharyngeal aspiration exposure to rod-like carbon nanotubes induces highly similar airway inflammation and biological pathways in mouse lungs

Project description:Inhalation and low-dose aspiration elicit highly similar pulmonary inflammation which was confirmed by activation of essentially similar biological pathways and even the same genes. Present results provide evidence that oropharyngeal aspiration is valid approach for hazard assessment of nanomaterials and proper alternative method for inhalation exposure.

The effects of timing of fine needle aspiration biopsies on gene expression profiles in breast cancers

Project description:Paired fine needle aspiration biopsies (FNABs) of breast cancers were taken before (PRE) and after (POST) surgeries from 16 patients and compared the cDNA microarray data to determine the genes that were differentially expressed between the FNABs taken at the two time points. The timing of fine needle aspiration biopsies can be a confounding factor in microarray data analyses in breast cancer. FOS-related genes, which have been implicated in early hypoxia as well as the development of breast cancers, were differentially expressed before and after surgery. Therefore, it is important that future studies take timing of tissue acquisition into account. Keywords: Breast cancer, fine needle, biopsy timing, microarray standardization, early hypoxic genes

TRANSCRIPTOMIC ANALYSIS ON ENDOSCOPIC ULTRASOUND FINE NEEDLE ASPIRATION MATERIALS FROM PRIMARY PANCREATIC ADENOCARCINOMA

Project description:The study aimed to compare the molecular profiles of metastatic, locally advanced, and resected primary pancreatic adenocarcinoma at the genomic and transcriptomic levels. DNA and mRNA were extracted from endoscopic ultrasound-guided fine needle aspiration-biopsy material of primary tumors from 397 patients, and they were subsequently analyzed by targeted deep sequencing and RNAseq.

Lyophilized human cells stored at room temperature preserve multiple RNA species at excellent quality for RNA sequencing

Project description:Purpose: We aimed to examine whether eukaryotic cell lyophilization and long-term storage would be feasible as an environmentally friendly and cheap alternative to cryogenic storage or the use of FFPE samples for large-scale RNA profiling studies. Brief method: On three different days three million GM12873 cells were taken up in 0.1 M trehalose, subjected to lyophilization (freeze-drying) and then stored for two weeks at room temperature in the presence of CaCl2 in a dark, tightly sealed box. Fresh paired control cells were pelleted and taken up in trizol without lyophilization. Total RNA was isolated using a modified trizol method, quantified and subjected to mRNA-Seq library preparation. Samples were sequenced using a NextSeq 500 instrument to 75 bp (single-end). Raw reads were aligned to the hg19 genomic build with TopHat 2.0.7 and gene expression quantification was performed using Cufflinks. Results: We found that lyophilized cells are highly similar in all inferred RNA-Seq quality metrics compared to their non-lyophilized controls and are useful sources of high-quality RNA for both small and large-scale studies. Conslusion: Lyophilization might be the preservation technique of choice in the future for studies aiming to involve large sample sets, such as clinical studies.

Gene expression analysis of lung cancer using long time stored formalin-fixed and paraffin embedded (FFPE) tissue

Project description:This study was performed to evaluated RNA extraction and gene expression analysis of FFPE specimen stored for more than 20 years. Using long time stored FFPE material; large retrospective studies correlating molecular features with therapeutic response and clinical outcome, can be performed. Quantitative PCR (qPCR) was used to evaluate RNA extraction methods and to compare gene expression profiles of FFPE and fresh frozen (FF) tissue. Extracted RNA was subsequently subjected to microarray analysis and compared to qPCR data. The Ambion RecoverAll kit appears to be particularly suited for RNA extraction of long time stored FFPE tissues. Gene expression analysis using Affymetrix platform displayed a high degree of correlation for endogenous control genes comparing FF and FFPE tissues. We conclude that high quality gene expression signatures can be recognized using Affymetrix gene expression platform on FFPE tissue stored for more than 20 years. However, a general interpretation must be done with caution as different FFPE procedures have varying effects on RNA quality.

Contact versus contactless signatures in leukemia

Project description:Gene expression profile (GEP) was analyzed in bone marrow (BM) samples from patients with leukemia or leukemic phase of lymphoma at different time points following aspiration. Among numerous changes in GEP evolved over time a discrete subset of > 60 genes exhibited prompt and sustained switch in expression consistently. Similar results were discovered recently in BM samples from patients with multiple myeloma (GSE36036). GEP was also examined in peripheral blood as well as in BM samples depleted of red blood cells (=WBC) and in cultured cells from some of the patients.
