The respiratory system is a complex network of many cell types, including subsets of macrophages and dendritic cels, that work together to maintain steady-state respiration. Due to limitations in acquiring cells from healthy human lung, these subsets remain poorly characterized transcriptionally and phenotypically. We set out to systemically identify these subsets in human airways, by developing a schema of isolating large numbers of cells by whole lung bronchoalveolar lavage. Six subsets of phagocytic antigen presenting cells were consistently observed, which varied in their ability to internalize bacterial particles. Subsets could be further separated by their inherent capacities to upregulate CD83, CD86, and CCR7. Whole genome transcriptional profiling revealed a clade of true dendritic cells distinct from a macrophage/monocyte clade. Each clade, and each member of both clades, could be discerned by specific genes of increased expression, which would serve as markers for future studies in healthy and diseased states.

View SamplesStat5a and Stat5b proteins are highly homologous with greater than 90% amino acid identity and share binding to the palindromic Stat5 consensus sequence, TTCNNNGAA, but individual roles of each transcription factor in breast cancer have not been thoroughly evaluated. To determine the degree of similarity between transcripts modulated by Stat5a and Stat5b proteins in human breast cancer, we utilized genome-wide transcript profiling to identify genes regulated specifically by Stat5a or Stat5b in response to prolactin.
Low levels of Stat5a protein in breast cancer are associated with tumor progression and unfavorable clinical outcomes.

View SamplesSenescence is a state of stable cell cycle exit that has important implications for development, physiology and disease. It is distinct from quiescence in which cells can be induced to re-enter the cell cycle. Although it is well known that there are massive changes in the heterochromatin of senescent cells, the molecular mechanisms underpinning the transition from reversible quiescence into irreversible senescence have remained elusive. Here, we demonstrate that the chromatin-remodeling enzyme ATRX is required for senescence. ATRX accumulates in nuclear foci during both replicative and cellular senescence. Using ChIP-seq and RNA-seq we identified HRAS as part of an ATRX regulated gene expression program associated with senescence. Repression of HRAS is sufficient to promote the transition of quiescent cells into senescence. Thus we conclude that the repression of HRAS is likely a direct consequence of ATRX binding and critical to how it mediates its role in senescence. Overall design: mRNA expression profiles were analyzed in dedifferentiated liposarcoma cell lines under cycling, quiescent and senescent (using two unique inducers) conditions via RNA-seq
ATRX is a regulator of therapy induced senescence in human cells.
