Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Biomarkers that predict disease progression might assist the development of better therapeutic strategies for aggressive cancers, such as ovarian cancer. Here, we investigated the role of collagen type XI alpha 1 (COL11A1) in cell invasiveness and tumor formation and the prognostic impact of COL11A1 expression in ovarian cancer. Microarray analysis suggested that COL11A1 is a disease progression-associated gene that is linked to ovarian cancer recurrence and poor survival.
Publication Title
COL11A1 promotes tumor progression and predicts poor clinical outcome in ovarian cancer.

Description
Embryonal tumors of the central nervous system (CNS) represent a highly malignant tumor group of medulloblastoma (MB), atypical teratoid/rhabdoid tumor (AT/RT), and primitive neuroectodermal tumor (PNET) that frequently afflict children. In this study, we report transcriptome traits in MB by using gene expression microarray analyses. We also compare MB dataset with AT/RT cases and AT/RT-like cases.

Description
Pediatric embryonal brain tumor (PEBT), which includes medulloblastoma (MB), primitive neuroectodermal tumor (PNET) and atypical teratoid/rhabdoid tumor (AT/RT), is the second most prevalent pediatric tumor type among brain tumors of childhood. AT/RT is highly malignant and is often misdiagnosed as MB and PNET. Distinguishing AT/RT from PNET/MB is of clinical significance since the survival rate of AT/RT patients is much lower. The diagnosis of AT/RT relies primarily on the morphologic assessment and immunohistochemistry (IHC) staining on a few known markers such as the lack of INI1 protein expression. However, in our clinical practice we observed several AT/RT-like tumors, which fulfilled histopathologic and all other biomarker criteria for AT/RT diagnosis, still showed retained INI1 immunoreactivity. Recent studies also reported retained INI1 immunoreactivity among certain diagnosed AT/RTs. It is therefore necessary to re-evaluate INI1(+), AT/RT-like cases. Sanger sequencing, array CGH and mRNA microarray analyses were performed on PEBT samples for studying their genomics landscapes. AT/RT and INI(+) AT/RT-like patients had similar survival rate, and global array CGH analysis and INI1 gene sequencing showed there is no differential chromosomal aberration marker between INI1(-) AT/RT and INI(+) AT/RT-like cases. We did not misdiagnose MB or PNET as AT/RT-like cases since transcriptome profiling revealed that not only AT/RT and INI(+) AT/RT-like cases expressed distinct mRNA and microRNA profiles, and their gene expression patterns were different from those of MBs and PNETs. AT/RTs shared the closest transcriptome profile to embryonic stem cells, INI1(+) AT/RT-like tumors were more similar to somatic neural stem cell, while MBs were closer to fetal brain. Novel biomarkers were identified to distinguish INI1(-) AT/RTs, INI1(+) AT/RT-like cases and MBs. Our studies disclosed a novel INI1(+) ATRT-like subtype among Taiwanese pediatric cases. New diagnostic biomarkers, as well as new therapeutic tactics, can be developed according to the transcriptome information unveiled in this work.

Description
Analysis of mechano-regulation of mesenchymal stem cell gene expression level. The hypothesis tested in the present study was that laminar shear stress influences the cytoskeleton arrangement and amount and then triggers seriers of cell metabolism and cellular functions. Results provide important information of the response of mesenchymal stem cell to laminar shear stress, such as specific mechano-responsive genes, up- or down-regulated specific anabolic/catabolic cellular functions.
Publication Title
Alteration of mesenchymal stem cells polarity by laminar shear stimulation promoting β-catenin nuclear localization.
