- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Epithelial to mesenchymal transition (EMT) in cancer cells has been associated with metastasis, stemness and resistance to therapy. The reason why some tumors undergo EMT and other not might reflect intrinsic properties of their cell of origin, although this possibility is largely unexplored. By targeting the same oncogenic mutations to discrete skin compartments, we show cell type-specific chromatin and transcriptional states differentially prime tumors to EMT. Squamous cell carcinomas (SCCs) derived from intrafollicular epidermis (IFE) are generally well-differentiated, while hair follicle (HF) stem cell-derived SCCs frequently exhibit EMT, efficiently form secondary tumors, and possess increased metastatic potential. Transcriptional and epigenomic profiling revealed IFE and HF tumor-initiating cells possess distinct chromatin landscapes and gene regulatory networks associated with tumorigenesis and EMT that correlate with accessibility of key epithelial and EMT transcription factor binding sites. These findings highlight the importance of chromatin states and transcriptional priming in dictating tumor phenotypes and EMT.

IlluminaHiSeq2500
Description
Comparison of the transcriptome of human kideny cancer cells either wild-type for FH or FH-deficient. The UOK262 cells were isolated from mediastinum metastasis of a HLRCC patient (Yang et al. Cancer Genetics and Cytogenetics, Volume 196, Issue 1, 1 January 2010, Pages 45–55). FH function was restored in the UOK262 by re-expressing the FH transcript from an exogenous plasmid. Overall design: Examination of gene transciption in 2 cell types.

Description
Comparison of the transcriptome of immortalised mouse kidney epithelial cells either wt for Fh1 or Fh1-deficient. The cells were isolated from kidneys of P5 mouse(see Frezza et al, Nature 2011). Briefly, Fh1_fl (flox) are wt for Fh1 (floxed cassette not excised), clone 1 and clone 19 are two different Fh1-deificent clones (floxed cassette excised) and Rec are clone 19 with reconstituted Fh1 expression from exogenous plasmid. Overall design: Examination of gene transciption in 4 cell types.

Description
Accumulating data indicate translation plays a role in cancer biology, particularly its rate limiting stage of initiation. Despite this evolving recognition, the function and importance of specific translation initiation factors is unresolved. The eukaryotic translation initiation complex eIF4F consists of eIF4E and eIF4G at a 1:1 ratio. Although it is expected that they display interdependent functions, several publications suggest independent mechanisms. This study is the first to directly assess the relative contribution of eIF4F components to the expressed cellular proteome, transcription factors, microRNAs, and phenotype in a malignancy known for extensive protein synthesis- multiple myeloma (MM). Previously, we have shown that eIF4E/eIF4GI attenuation (siRNA/ Avastin) deleteriously affected MM cells' fate and reduced levels of eIF4E/eIF4GI established targets. Here, we demonstrated that eIF4E/eIF4GI indeed have individual influences on cell proteome. We used an objective, high throughput assay of mRNA microarrays to examine the significance of eIF4E/eIF4GI silencing to several cellular facets such as transcription factors, microRNAs and phenotype. We showed different imprints for eIF4E and eIF4GI in all assayed aspects. These results promote our understanding of the relative contribution and importance of eIF4E and eIF4GI to the malignant phenotype and shed light on their function in eIF4F translation initiation complex.
Publication Title
eIF4E and eIF4GI have distinct and differential imprints on multiple myeloma's proteome and signaling.
