TranscriptomicsEffects of Rituximab on global gene expression profiles in the RA synovium
Objective: Rituximab displays therapeutic benefits in the treatment of rheumatoid arthritis (RA) patients resistant to TNF blockade. However, the precise role of B cells in the pathogenesis of RA is still unknown. In this study we investigated the global molecular effects of rituximab in synovial bi...

TranscriptomicsHuman memory T cells of the bone marrow are resting and maintain long-lasting memory
To compare human memory CD4+ T cell subsets in peripheral blood (PB) and bone marrow (BM) of healthy individuals at transcriptional level, we analyzed the global gene expression of ex vivo PB CD69- as well as BM CD69- and CD69+ memory CD4+ T cells from 4 paired PB and BM samples. The gene expression...

TranscriptomicsInfluence of BrpA on critical virulence attributes of Streptococcus mutans
Streptococcus mutans, the primary etiological agent of human dental caries, has developed multiple mechanisms to colonize and form biofilms on the tooth surface. The brpA gene codes for a predicted surface-associated protein with apparent roles in biofilm formation, autolysis, and cell division. In ...

GenomicsThe Hippo tranducer YAP1 transforms activated satellite cells and is a potent effector of embryonal rhabdomyosarcoma formation
The Hippo pathway effector YAP1 controls stem cell fate in epithelial tissues, but its role in stem cells of non-epithelial tissues, such as skeletal muscle, is poorly documented. Here we show that sustained YAP1 activity in mouse activated satellite cells in vivo induces rhabdomyosarcoma (RMS) rese...

TranscriptomicsTranscriptional profiling of lncRNAs and novel transcribed regions across a diverse panel of archived human cancers
Molecular characterization of tumors has been critical for identifying important genes in cancer biology and for improving tumor classification and diagnosis. Long non-coding RNAs (lncRNAs), as a new, relatively unstudied class of transcripts, provide a rich opportunity to identify both functional d...

TranscriptomicsInhibition of the LSD1 (KDM1A) demethylase reactivates the all-trans-retinoic acid differentiation pathway in acute myeloid leukemia [Illumina HumanHT-12 gene expression array]
All-trans-retinoic acid (ATRA) has been successfully used in therapy of acute promyelocytic leukemia (APL), a cytogenetically distinct subtype of acute myeloid leukemia (AML) but the response of non-APL AML cases to ATRA-based treatment has been poor. Here we show that, via epigenetic reprogramming,...

TranscriptomicsHost cell-free growth of the Q fever bacterium Coxiella burnetii
The inability to propagate obligate intracellular pathogens under axenic (host cell-free) culture conditions imposes severe experimental constraints that have negatively impacted progress in understanding pathogen virulence and disease mechanisms. Coxiella burnetii, the causative agent of human Q (Q...

TranscriptomicsGlycogen Accumulation in Chlamydia trachomatis is Controlled by its Plasmid Through Regulation of glgA
C. trachomatis possess a cryptic 7.5 kb plasmid of unknown function. Here we describe a comprehensive molecular and biological characterization of the naturally occurring plasmidless human Chlamydia trachomatis strain L2 (25667R). We found that despite minimal chromosomal polymorphisms the LGV L2 ...
