Project description:Objective: The etiology of PCOS is mostly unknown. Existing data support both genetic and environmental factors in its pathogenesis. Design: Prospective case - control study. Setting: University Hospital. Patients: 25 patients undergoing IVF-ICSI treatment. Intervention: Genome-wide oligonucleotide microarray technology was used to study differential gene-expression patterns of cultured human cumulus cells from IVF patients divided into 4 groups according to disease state (PCOS vs. Control) and BMI (Obese vs. Lean). Results: Two differential PCOS gene expression profiles were established: Lean-Type was formed by comparing PCOS lean (PL) vs. non-PCOS lean (NL) individuals; Obese-Type was formed by comparing PCOS obese (PO) vs. non-PCOS (NO) obese patients. Conclusions: Different molecular pathways are associated with PCOS in Lean and Obese individuals, as demonstrated by gene expression profiling of cumulus cells. Our findings provide insights into the molecular pathogenesis of PCOS. We used microarrays to study the gene expression of human cultured cumulus cells. We compared the genes expression of lean PCOS, Obese PCOS, lean controls and obese controls. Different molecular pathways are associated with PCOS in Lean and Obese patients. Experiment Overall Design: Cumulus cells obtained from woman undergoing IVF/ICSI. Following oocyte retrieval, cumulus cells were stripped from the oocyte, in preparation for the ICSI process, with a micropipette. After 48h in culture the cumulus cells were collected for RNA extraction and hybridization on Affymetrix microarrays. We compered the expression profile of 4 groups - lean PCOS, obese PCOS, lean controls and obese controls.

Project description:Using Smart-seq2 single cell sequencing we reported that plasmablasts from dengue-infected individuals separate into 4 distinct clusters with distinct function.
Project description:We performed the single cell RNA-seq for the Hoxb5 Mac-1+CD48+ SK cells, bone marrow HSC, bone marrow MPP, and fetal liver HSC by Smart-Seq2.
Project description:Smart-seq2 single cell RNA sequencing reads from kidney glomerular single cells of healthy human individuals. The dataset contains single-end fastq files of 766 single cells.
Project description:Four Kcng4-cre;stop-YFP mouse retinas from two mice were dissected, dissociated and FACS sorted, and single cell RNA-seq libraries were generated for 384 single cells using Smart-seq2. Aligned bam files are generated for 383 samples as one failed to align. Four mouse retinas (labeled 1la, 1Ra, and 2la, 2Ra respective from the two mice) were used, and 96 single cells from each were processed using Smart-seq2. Total 384 cells Smart-seq2 analysis of P17 FACS sorted retinal cells from the Kcng4-cre;stop-YFP mice (Kcng4tm1.1(cre)Jrs mice [Duan et al., Cell 158, 793-807, 2015] crossed to the cre-dependent reporter Thy1-stop-YFP Line#1 [Buffelli et al., Nature 424, 430-434, 2003])
Project description:Longitudinal single cell RNA-expression analysis of tumor cells along the metastatic cascade. AKTP MTOs were implanted in the caecum and left to metastasize into the liver. Mice with different metastatic burden were collected and GFP+ CD45- cells were sorted in 96-well smart-seq plates. Tumor cells were collected at four stages (Primary tumors, micrometastases, small metastases and big metastases) and each Smart-seq2 plate contained cells from all conditions to avoid batch effects. Primary tumor samples were matched with micro, small or big metastases samples.
