Three-dimensional (3D) chromatin structure is an emerging paradigm for understanding gene regulation mechanisms. Hi-C (high-throughput chromatin conformation capture), a method to detect long-range chromatin interactions, allows extensive genome-wide investigation of 3D chromatin structure. However, broad application of Hi-C data have been hindered by the level of complexity in processing Hi-C ...
New therapies for late stage and castration resistant prostate cancer (CRPC) depend on defining unique properties and pathways of cell sub-populations capable of sustaining the net growth of the cancer. One of the best enrichment schemes for isolating the putative stem/progenitor cell from the murine prostate gland is Lin(-);Sca1(+);CD49f(hi) (LSC(hi)), which results in a more than 10-fold enri...
Tumor-associated macrophages (TAM) are exposed to multiple microenvironmental cues in tumors, which collaborate to endow these cells with protumoral activities. Hypoxia, caused by an imbalance in oxygen supply and demand because of a poorly organized vasculature, is often a prominent feature in solid tumors. However, to what extent tumor hypoxia regulates the TAM phenotype in vivo is unknown. H...
The origin of wound repair macrophages is incompletely defined and was examined here in sterile wounds using the subcutaneous polyvinyl alcohol sponge implantation model in mice. Phenotypic analysis identified F4/80(+)Ly6C(hi)CD64(+)MerTK(-) monocytes and F4/80(+)Ly6C(low)CD64(+)MerTK(+) macrophages in the wound. Circulating monocytes were the precursors of inflammatory Ly6C(hi) wound monocytes...
Harlequin ichthyosis (HI)--the most severe form of keratinizing disorders, often lethal in the neonatal period--is characterized by a profound thickening of the keratin skin layer, a dense "armor"-like scale that covers the body, and contraction abnormalities of the eyes, ears, and mouth. In this issue of the JCI, Akiyama et al. report that mutations in ABCA12 caused defective lipid transport t...
During the human B cell (Bc) recall response, rapid cell division results in multiple Bc subpopulations. The TLR-9 agonist CpG oligodeoxynucleotide, combined with cytokines, causes Bc activation and division in vitro and increased CD27 surface expression in a sub-population of Bc. We hypothesized that the proliferating CD27(lo) subpopulation, which has a lower frequency of antibody-secreting ce...
We describe Hi-C, a method that probes the three-dimensional architecture of whole genomes by coupling proximity-based ligation with massively parallel sequencing. We constructed spatial proximity maps of the human genome with Hi-C at a resolution of 1 megabase. These maps confirm the presence of chromosome territories and the spatial proximity of small, gene-rich chromosomes. We identified an ...
OBJECTIVE Prompt post-hypoxia-ischemia (HI) revascularization has been suggested to improve outcome in adults and newborn subjects. Other than hypoxia-inducible factor, sensors of metabolic demand remain largely unknown. During HI, anaerobic respiration is arrested resulting in accumulation of carbohydrate metabolic intermediates. As such succinate readily increases, exerting its biological eff...
Chloride intracellular channel (CLIC) is a member of the chloride protein family for which growing evidence supports pivotal role in fundamental cellular events. However, physiological function CLIC insects still rarely uncovered. The ovary-derived High Five (Hi-5) cell line isolated from cabbage looper ( Trichoplusia ni ) widely used laboratories. Here, we studied both characteristics and func...
To examine the influence of exercise intensity on the increases in vastus lateralis GLUT4 mRNA and protein after exercise, six untrained men exercised for 60 min at 39 +/- 3% peak oxygen consumption (V(O2 peak)) (Lo) or 27 +/- 2 min at 83 +/- 2% V(O2 peak) (Hi) in counterbalanced order. Preexercise muscle glycogen levels were not different between trials (Lo: 408 +/- 35 mmol/kg dry mass; Hi: 42...
