Genome-wide analysis of serum starved prelamin A-accumulating hMSCs gene expression.

ABSTRACT: Analysis of serum starved prelamin A-accumulating hMSCs at gene expression level. The hypothesis tested in the present study was that prelamin A accumulation induces the dysregulation of genes that are essensial for cell survival under a stress condition such as serum starvation. The results provide important information about these genes and the functional categories that are dysregulated due to prelamin A accumulation in serum starved hMSCs.

Genome-wide analysis of serum starved prelamin A-accumulating hMSCs gene expression.

Project description:Analysis of serum starved prelamin A-accumulating hMSCs at gene expression level. The hypothesis tested in the present study was that prelamin A accumulation induces the dysregulation of genes that are essensial for cell survival under a stress condition such as serum starvation. The results provide important information about these genes and the functional categories that are dysregulated due to prelamin A accumulation in serum starved hMSCs. Two samples are analyzed in this microarray experiment: human mesenchymal stem cell cultured under serum starvation conditions (during 24 hours) which accumulate prelamin A (pre-hMSCs) and control mesenchymal stem cells (ctrl-hMSCs). 2 biological replicates (hMSCs derived from 2 different bone marrow donors) and 1 technical replicate are included in this analysis.

Comparison of HEK293T cells grown in serum supplemented media to cells serum starved for 3 days

Project description:HEK293T cells grown to confluence in media +10% fetal bovine serume. Media was removed and replaced with serum free media, and cultured for 3 days. RNA was harvested from day0 (serum supplemented), control, and day3 (serum starved) cultures, experiment.

MicroRNA transcriptional profiling in serum-starved human aortic smooth muscle cells

Project description:We sought to identify microRNAs that were differentially regulated in cultured primary human aortic smooth muscle cells (SMCs) when exposed to growth arrest via serum starvation over two time points - 48 hours and 72 hours, when compared with serum-fed cells. This treatment leads to increased expression of SMC differentiation markers such as ACTA2, MYH11 and TAGLN. We identified 31 significantly regulated miRNA candidates during this process, 28 rising and 3 falling. Human aortic SMCs (AoSMCs) were propagated in growth media. Control plates were harvested, and the remaining plates were serum starved for 48 (SS48) or 72 hours (SS72) in serum-free basal media. Several arrays were excluded from final analysis after QC, resulting in a final set of 10.

Human Mesenchymal Stem Cells (hMSCs): Fibroblast vs. hMSCs from various origins

Project description:To identify the key microRNAs (miRNAs) of hMSCs required for fate determination, miRNA profiling was performed with hMSCs from three different sources including adipose-derived stem cells (ADSCs), bone-marrow-derived stem cells (BMSCs), and umbilical cord-derived stem cells (UCSCs) versus fibroblasts, a more differentiated mesenchymal cell types. We compared the expression profiles of two different donors per hMSCs to that of fibroblasts. All hMSCs were used for profiling at passage 3-6.

Transcription profiling of human foreskin fibroblasts CRL 2091 (ATCC) serum starved for 48 hours, Serum Stimulation time series

Project description:Foreskin fibroblasts CRL 2091 (ATCC) were serum starved for 48 hours, and harvested at the indicated time points after switching to media with 10% FBS essentially as described (Iyer et al., 1999). RNA from all of the sampled time points were pooled as reference RNA to compare with RNA from individual time points as described (Iyer et al., 1999).
