The c-Myc HLH-bZIP protein has been implicated in physiological or pathological growth, proliferation, apoptosis, metabolism, and differentiation at the cellular, tissue, or organismal levels via regulation of numerous target genes. No principle yet unifies Myc action due partly to an incomplete inventory and functional accounting of Myc's targets. To(More)
Chromatin modifications have been implicated in the self-renewal and differentiation of embryonic stem cells (ESCs). However, the function of histone variant H2A.Z in ESCs remains unclear. We show that H2A.Z is highly enriched at promoters and enhancers and is required for both efficient self-renewal and differentiation of murine ESCs. H2A.Z deposition(More)
Innate lymphoid cells (ILCs) are critical in innate immune responses to pathogens and lymphoid organ development. Similar to CD4(+) T helper (Th) cell subsets, ILC subsets positive for interleukin-7 receptor α (IL-7Rα) produce distinct sets of effector cytokines. However, the molecular control of IL-7Rα(+) ILC development and maintenance is unclear. Here,(More)
T-bet is a critical transcription factor for T helper 1 (Th1) cell differentiation. To study the regulation and functions of T-bet, we developed a T-bet-ZsGreen reporter mouse strain. We determined that interleukin-12 (IL-12) and interferon-γ (IFN-γ) were redundant in inducing T-bet in mice infected with Toxoplasma gondii and that T-bet did not contribute(More)
Enhancers of transcription activate transcription via binding of sequence-specific transcription factors to their target sites in chromatin. In this report, we identify GATA1-bound distal sites genome-wide and find a global reorganization of the nucleosomes at these potential enhancers during differentiation of hematopoietic stem cells (HSCs) to(More)
Although intergenic long noncoding RNAs (lincRNAs) have been linked to gene regulation in various tissues, little is known about lincRNA transcriptomes in the T cell lineages. Here we identified 1,524 lincRNA clusters in 42 T cell samples, from early T cell progenitors to terminally differentiated helper T cell subsets. Our analysis revealed highly dynamic(More)
Embryonic stem cell (ESC) pluripotency requires bivalent epigenetic modifications of key developmental genes regulated by various transcription factors and chromatin-modifying enzymes. How these factors coordinate with one another to maintain the bivalent chromatin state so that ESCs can undergo rapid self-renewal while retaining pluripotency is poorly(More)

Immunol. 16, 1114–1123 (2015); published online 20 October 2015; corrected after print 13 November 2015 In the version of this article initially published, the vertical axes of Figure 4 were labeled incorrectly as “(per 1 × 105 T cells).” The correct label is “(per 1 × 106(More)
Seronegative hepatitis--non-A, non-B, non-C, non-D, non-E hepatitis--is poorly characterized but strongly associated with serious complications. We collected 92 sera specimens from patients with non-A-E hepatitis in Chongqing, China between 1999 and 2007. Ten sera pools were screened by Solexa deep sequencing. We discovered a 3,780-bp contig present in all(More)
Histone H3 variant H3.3, while differing from canonical H3 (H3.1) by only five amino acids, is assembled into nucleosomes, along with histone H4, at genic regions by the histone chaperone HIRA, whereas H3.1 is assembled into nucleosomes in a CAF-1-dependent reaction. Here, we show that phosphorylation of histone H4 Ser 47 (H4S47ph), catalyzed by the PAK2(More)
