Transcriptome analysis of pancreatic cancer cell line that differ in metastatic potential
  • organism-icon Homo sapiens
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Two pancreatic cancer cell lines with different metastatic and growth potential were compared under hypoxic conditions and under normal atmospheric oxygen pressure. The FG cell lines shows very few metastases and slow growth in mouse xenograft models. L3.6pl, derived from FG by cycles re-implantation of metastatic cells obtained after orthotopic tumor growth in nude mice, shows high motility, aggressive growth and very high metastatic potential

Publication Title

Hypoxia-independent gene expression mediated by SOX9 promotes aggressive pancreatic tumor biology.

Comparative gene expression analysis of mesenchymal stem cells (MSC) derived from non-small cell lung cancer (NSCLC) and corresponding normal lung tissue (NLT)
  • organism-icon Homo sapiens
  • sample-icon 9 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

The stromal microenvironment plays a vital role in cancer initiation and progression. We performed a comparative expression profiling of pulmonary MSC derived from NSCLC and corresponding normal lung tissue of 5 newly diagnosed patients. The analysis indicated variable expression of genes involved in DNA repair, apoptosis, proliferation or angiogenesis between NSCLC-MSC and NLT-MSC.

Converting Oct6 into a pluripotency inducer by interrogating Oct4 residues
  • organism-icon Mus musculus
  • sample-icon 10 Downloadable Samples
  • Technology Badge IconIllumina MouseRef-8 v2.0 expression beadchip

Description

In this study, we set out to identify those molecular features of the POU transcription factor Oct4 that are responsible for inducing pluripotency in somatic cells. Oct4 is known to have a strong preference to cooperate with Sox2 on heterodimeric SoxOct elements predominantly found in enhancers of genes expressed in embryonic stem cells (ESCs). To test whether this partnership is specific to Oct4, we compared its DNA recognition and reprogramming activities to the paralogous transcription factor Oct6, which cannot induce and maintain pluripotency in mouse cells. By analyzing ChIP-Seq data and performing quantitative dimerization assays, we found that in somatic cells, instead of heterodimerzing with Sox-factors, Oct6 more potently homodimerizes on OctOct elements. We identified that a single amino acid is crucial in directing binding to the respective composite DNA element. As a consequence, just changing this one amino acid hampers Oct4 in generating induced pluripotent stem cells (iPSCs). In contrast, the reverse mutation in Oct6 did not augment its reprogramming activity. This was achieved with at least two additional exchanges. In summary, we demonstrate that cell-type specific POU factor function is determined by a limited set of residues that affect DNA and partner factor interactions. Such relatively minor changes lead to a pronounced impact on regulatory function and reprogramming activity.

Changing POU dimerization preferences converts Oct6 into a pluripotency inducer.

Cell Fusion Enhances Mesendodermal Differentiation of Human Induced Pluripotent Stem Cells
  • organism-icon Homo sapiens
  • sample-icon 11 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Gene 1.0 ST Array (hugene10st)

Description

Human induced pluripotent stem cells (iPS cells) resemble embryonic stem cells and can differentiate into cell derivatives of all three germ layers. However, frequently the differentiation efficiency of iPS cells into some lineages is rather poor. Here, we found that fusion of iPS cells with human hematopoietic stem cells (HSC) enhances iPS cell differentiation. Such iPS hybrids showed a prominent differentiation bias towards hematopoietic lineages but also towards other mesendodermal lineages. Additionally, during differentiation of iPS hybrids expression of early mesendodermal markers - Brachyury (T), MIX1 Homeobox-Like Protein 1 (MIXL1) and Goosecoid (GSC) - appeared with faster kinetics than in parental iPS cells. Following iPS hybrid differentiation there was a prominent induction of NODAL and inhibition of NODAL signaling blunted mesendodermal differentiation. This indicates that NODAL signaling is critically involved in mesendodermal bias of iPS hybrid differentiation. In summary, we demonstrate that iPS cell fusion with HSC prominently enhances iPS differentiation.
