Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Oncogenic human papillomaviruses (HPVs) are associated with nearly all carcinomas of the uterine cervix and have also become an increasingly important factor in the etiology of a subset of oropharyngeal tumors. HPV-associated head and neck cancers (HNSCCs) have a distinct risk profile and appreciate a prognostic advantage compared to HPV-negative HNSCC. We analyzed the genome-wide expression patterns in two HPV(+) and two HPV(-) squamous cell carcinoma (SCC) cell lines.

Description
Purpose: There is substantial heterogeneity within the human papillomavirus (HPV) positive head and neck cancer (HNC) tumors that predispose them to different outcomes, however this subgroup is poorly characterized due to various historical reasons. Experimental Design: we perform unsupervised gene expression clustering on well-annotated HPV(+) HNC samples from two cohorts ( 84 total primary tumors), as well as 18 HPV(-) HNCs, to discover subtypes, and begin to characterize the differences between the subtypes in terms of their HPV characteristics, pathway activity, whole-genome somatic copy number variations and mutation frequencies. Results: We identified two distinctive HPV(+) subtypes by unsupervised clustering. Membership in the HPV(+) subtypes correlates with genic viral integration status, E2/E4/E5 expression levels and the ratio of spliced to full length HPV oncogene E6. The subtypes also show differences in copy number alterations, in particular the loss of chr16q and gain of chr3q, PIK3CA mutation, and in the expression of genes involved in several biological processes related to cancer, including immune response, oxidation-reduction process, and keratinocyte and mesenchymal differentiation. Conclusion: Our characterization of two subtypes of HPV(+) tumors provides valuable molecular level information in relation to the alternative paths to tumor development and to that of HPV(-) HNCs. Together, these results will shed light on stratifications of the HPV(+) HNCs and will help to guide personalized care for HPV(+) HNC patients. Overall design: 36 head and neck primary tumors (18 HPV+ and 18 HPV-) and their matched blood samples were collected and genotyped by Illumina OmniExpress SNP array. RNA-seq was also performed on the same set of tumor samples.

Description
The adaptor protein Lnk is an important negative regulator of HSC homeostasis and self-renewal. This study aims to investigate the role of Lnk in HSC aging. Here we performed expression profiling of bone marrow CD150+CD48-LSK LT-HSCs from young and old WT and Lnk-/- mice. Results identify select Lnk-mediated pathways with potential involvement in HSC self-renewal and aging.
Publication Title
Lnk deficiency partially mitigates hematopoietic stem cell aging.

Description
Previous studies in our laboratory have shown that low folate diet (control diet with 2mg folate/kg, low folate diet with 0.3mg folate/kg) can induce intestinal tumors in BALB/c mice. In addition, we reported that C57Bl/6J mice did not form tumors under the same conditions.

Description
The adaptor protein MERIT40 is a core subunit of deubiquitinating (DUB) complexes that specifically cleave Lysine63-polyubiquitin chains. We found that MERIT40 is an important negative regulator of hematopoietic stem cell (HSC) homeostasis, quiescence and self-renewal. This study aims to investigate the molecular mechanism by which MERIT40 regulates HSC expansion and cell cycle. We performed expression profiling of bone marrow CD150+CD48-LSK LT-HSCs from WT and Merit40-/- mice. Results identify select MERIT40-mediated pathways with potential involvement in HSC cell cycle regulation.

MERIT40 deficiency expands hematopoietic stem cell pools by regulating thrombopoietin receptor signaling.
