TL;DR: The results demonstrate that the HIF-1/HRE system of gene regulation is active in hypoxic tumor cells and show the potential of exploiting tumor-specific conditions for the targeted expression of diagnostic or therapeutic genes in cancer therapy.
Abstract: Solid tumors with areas of low oxygen tension (hypoxia) have a poor prognosis, as cells in this environment often survive radiation and chemotherapy In this report we describe how this hypoxic environment can be used to activate heterologous gene expression driven by a hypoxia-responsive element (HRE), which interacts with the transcriptional complex hypoxia-inducible factor-1 (HIF-1) Our results demonstrate that the HIF-1/HRE system of gene regulation is active in hypoxic tumor cells and show the potential of exploiting tumor-specific conditions for the targeted expression of diagnostic or therapeutic genes in cancer therapy

TL;DR: These results provide the first demonstration of chemokine/chemokine-receptor activity in the navigation of macrophages toward apoptotic cells and identify a mechanism by which macrophage infiltration of tissues containing apoptotic lymphocytes is achieved.

TL;DR: Results suggest that airway epithelial S cells are localized to specific niches, as demonstrated by reconstitution of a surface-like epithelium from gland remnants after surface epithelial removal.
Abstract: It is generally important to elucidate airway epithelial cell lineages and to identify multipotent progenitors as targets for gene therapy. Stem (S) cells are typically present in specialized compartments spatially proximal to their differentiated progeny, but an equivalent paradigm has not been demonstrated in the airway. We discovered a distinct population of cells displaying high levels of keratin expression in murine tracheal submucosal gland ducts, and tested the hypothesis that bromodeoxyuridine (BrdU) label-retaining cells (LRCs), thought to represent the S-cells, were present in this compartment. Mice received weekly epithelial damage by intratracheal detergent or SO(2) inhalation for 4 wk and received intraperitoneal injections of BrdU every 48 h during the injury and repair period. At 3 and 6 d after injury, BrdU-positive epithelial cells were noted along the entire tracheal length in both basal and lumenal cell positions. At later time points (20 and 95 d) LRCs were localized to gland ducts in the upper trachea and to systematically arrayed foci in the lower trachea, typically near the cartilage-intercartilage junction. LRCs were not pulmonary neuroendocrine cells. Heterotopic tracheal grafts after surface epithelial removal demonstrated reconstitution of a surface-like epithelium from gland remnants. These results suggest that airway epithelial S cells are localized to specific niches.

TL;DR: The value of sex-specific GWAS to unravel the sexually dimorphic genetic underpinning of complex traits is demonstrated, with no evidence for genetic effects with opposite directions in men versus women.
Abstract: Given the anthropometric differences between men and women and previous evidence of sex-difference in genetic effects, we conducted a genome-wide search for sexually dimorphic associations with height, weight, body mass index, waist circumference, hip circumference, and waist-to-hip-ratio (133,723 individuals) and took forward 348 SNPs into follow-up (additional 137,052 individuals) in a total of 94 studies. Seven loci displayed significant sex-difference (FDR<5%), including four previously established (near GRB14/COBLL1, LYPLAL1/SLC30A10, VEGFA, ADAMTS9) and three novel anthropometric trait loci (near MAP3K1, HSD17B4, PPARG), all of which were genome-wide significant in women (P<5×10(-8)), but not in men. Sex-differences were apparent only for waist phenotypes, not for height, weight, BMI, or hip circumference. Moreover, we found no evidence for genetic effects with opposite directions in men versus women. The PPARG locus is of specific interest due to its role in diabetes genetics and therapy. Our results demonstrate the value of sex-specific GWAS to unravel the sexually dimorphic genetic underpinning of complex traits.

TL;DR: The increased intestinal permeability to toxic "non-absorbable" compounds of less than 5000 molecular weight may account for some of the extraintestinal tissue damage common in alcoholic patients.
