Comparing the transcriptome of naïve C57BL/6 CD44+/+ vs CD44-/- alveolar macrophages

ABSTRACT: Purpose: Determine if alveolar macrophage express different transcriptional programs when CD44 expression is lost. Methods: Alveolar macrophages were isolated from the bronchoalveolar lavage of 6-10 week old CD44+/+ and CD44-/- female mice. RNA was isolated an sequenced using Illumina NextSeq 500. RNA was sequenced by the UBC Biomedical Research Center. RNA quality, 18S and 28S ribosomal RNA with RIN = 9.6, was determined by Agilent 2100 Bioanalyzer following standard protocol for NEBnext Ultra ii Stranded mRNA (New England Biolabs). Sequencing was performed on the Illumina NextSeq 500 with paired end 42bp 42bp reads. De-multiplexed read sequences were then aligned to the Mus musculus (mm10) reference sequence using Spliced Transcripts Alignment to a Reference, STAR (https://www.ncbi.nlm.nih.gov/pubmed/23104886), aligners. Results and conclusion: Multiple pathways were abnormal in CD44-/- alveolar macrophages, in particular those involved in lipid metabolism and immune signaling.

Evaluation of gene expression between CD44+ and CD44- cells in colonospheres

Project description:To identify genes that are differentially expressed between CD44+ and CD44- cells in colonospheres, we have employed whole genome microarray expression profiling as a discovery platform. Colonospheres from four colon cancer patients were sorted into CD44+ and CD44- cells using the FACS Aria II Cell Sorter, and total RNA extracted from the cells were labeled with Cy3 and used for microarray analyses with Agilent Whole Human Genome Oligo Microarrays. Gene expression in fluorescence-activated cell-sorted CD44+ and CD44- cells derived from four colon cancer patients was measured.

Gene expression profiles in CD44- and CD44+ hepatocellular carcinoma HuH7 cells

Project description:To investigate the significance of CD44+ hepatocellular carcinoma (HCC) HuH7 cells, gene expression profiles of CD44-positive HuH7, CD44-negative HuH7, and human nomal hepatocyes were analyzed. Results provide the insight into the significance of CD44-positive HCC cells as the liver CSCs.

AmpliSeq transcriptome profiling of human adipose tissue senescent progenitor cells

Project description:Transcriptomic profile of human adipose tissue progenitor cells was performed as follows. For AmpliSeq transcriptome sequencing library construction, AmpliSeq™ Library PLUS, AmpliSeq Transcriptome Human Gene Expression Panel and AmpliSeq CD indexes SetA kits were purchased from Illumina and sequencing libraries were constructed as described in AmpliSeq for Illumina Transcriptome Human Gene Expression Panel reference guide (Illumina). Equimolar concentrations of libraries were pooled at 4 nM and denatured and diluted as described in Denature and Dilute Libraries Guide (Illumina) and adjusted to final concentration of 1.4 pM. Resulting library was sequenced on NextSeq 500 using NextSeq 500/550 High Output v2 kit with 2 X 151 bp cycle. Generated raw files were converted to FASTQ files and used for data analysis. AmpliSeq transcriptome FASTQ files were analyzed on Array studio V10.0 (Omicsoft, Qiagen). Following raw read QC, first and last 10 bases were trimmed and mapped to reference genome Human.B38. The read count data was generated using GeneModel RefGene20170606. Resulting data was normalized by DESeq package, transformed to log2 value and used for ANOVA analyses.

CD44+ or CD44– tumor cells isolated from K19-Wnt1/C2mE mice

Project description:We hypothesized that CD44+ tumor cells might have an increased capacity for reactive oxygen species (ROS) defense in the gastric tumors of K19-Wnt1/C2mE mice. To address this possibility, we examined the expression of antioxidant genes in tumor cells isolated from K19-Wnt1/C2mE mice by fluorescence-activated cell sorting (FACS). Lineage marker (Lin)–negative cells that were CD44+ or CD44– were thus isolated from the gastric tumors of 30-week-old K19-Wnt1/C2mE mice and subjected to cDNA microarray analysis. The expression of several key antioxidant genes, including those for glutathione peroxidase (GPX) and peroxiredoxin (PRDX) isoforms, was found to be increased in CD44+ tumor cells compared with that in CD44– cells.
