Expression of meningioma 1 (MN1) has been proposed to be a negative prognostic molecular marker in adult AML with normal cytogenetics, however its role in pediatric leukemia is unknown. We found elevated MN1 expression in 53 of 88 pediatric leukemia cases: significant amounts of MN1 were found in im ...See More

Ubiquitination is a post-translational mechanism of control of diverse cellular processes. We focus here on the ubiquitin ligase Fbw7, a recently identified hematopoietic tumor suppressor that can target for degradation several important oncogenes including Notch1, c-Myc and cyclin E. We have genera ...See More

Most human B cell lymphomas (B-NHL) are derived from germinal centers (GCs), the structure where B-cells undergo class switch recombination (CSR) and somatic hypermutation (SHM) and are selected for high-affinity antibody production. The pathogenesis of B-NHL is associated with distinct genetic les ...See More

Surface expression of the viral Envelope protein (Env) was used to enrich reactivated latent T cells producing HIV-RNA, and single cell RNASeq was performed to study gene expression differences between latent cells and controls. Overall design: Latent CD4+ T cells from virologically suppressed patie ...See More

The Hedgehog (Hh) signaling pathway is a developmentally conserved regulator of stem cell function. Several reports suggested that Hh signaling is an important regulator of hematopoietic stem cell (HSC) maintenance and differentiation. Here we test this hypothesis in vivo using both gain- and loss-o ...See More

Blimp-1 expression in T cells extinguishes the T follicular helper cell fate and drives terminal differentiation, but also limits autoimmunity. Although various factors have been described to control Blimp-1 expression in T cells, little is known about what regulates Blimp-1 expression in Th2 cells ...See More

Genome-wide analysis was performed on microRNA 155+/+ and -/- Th17 cells to determine the differentially expressed transcripts that are regulated by miR-155. We found that Jarid2 was differentially expressed in absence of miR-155 and highlight the mechanism for the silencing of IL-22 by Jarid2 and P ...See More

Trisomy 21 (Ts21) or Down syndrome (DS) is the most common genetic cause of intellectual disability. To investigate the consequences of Ts21 on human brain development, we have systematically analyzed the transcriptome of dorsolateral prefrontal cortex (DFC) and cerebellar cortex (CBC) using exon ar ...See More
