Rapamycin-mediated lifespan increase in mice is dose and sex dependent and metabolically distinct from dietary restriction
Rapamycin, an inhibitor of mTOR kinase, increased median lifespan of genetically heterogeneous mice by 23% (males) to 26% (females) when tested at a dose threefold higher than that used in our… Expand

Peptidoglycan Recognition Proteins Are a New Class of Human Bactericidal Proteins*
Skin and mucous membranes come in contact with external environment and protect tissues from infections by producing antimicrobial peptides. We report that human peptidoglycan recognition proteins 3… Expand

Human Peptidoglycan Recognition Protein-L Is an N-Acetylmuramoyl-L-alanine Amidase*
Peptidoglycan recognition proteins (PGRPs) are pattern recognition molecules coded by up to 13 genes in insects and 4 genes in mammals. In insects PGRPs activate antimicrobial pathways in the… Expand

Zebrafish peptidoglycan recognition proteins are bactericidal amidases essential for defense against bacterial infections.
Peptidoglycan recognition proteins (PGRPs) are structurally conserved through evolution, but their functions in innate immunity are different in invertebrates and vertebrates. We asked what the… Expand

PGLYRP-2 and Nod2 are both required for peptidoglycan-induced arthritis and local inflammation.
Peptidoglycan recognition proteins (PGRPs) are structurally conserved from insects to mammals. Insect PGRPs have diverse host-defense functions. Mammalian PGRPs PGLYRP-1, PGLYRP-3, and PGLYRP-4 have… Expand

Human Peptidoglycan Recognition Proteins Require Zinc to Kill Both Gram-Positive and Gram-Negative Bacteria and Are Synergistic with Antibacterial Peptides1
Mammals have four peptidoglycan recognition proteins (PGRPs or PGLYRPs), which are secreted innate immunity pattern recognition molecules with effector functions. In this study, we demonstrate that… Expand

Genome Sequence and Transcriptome Analysis of the Radioresistant Bacterium Deinococcus gobiensis: Insights into the Extreme Environmental Adaptations
The desert is an excellent model for studying evolution under extreme environments. We present here the complete genome and ultraviolet (UV) radiation-induced transcriptome of Deinococcus gobiensis… Expand

Peptidoglycan recognition proteins protect mice from experimental colitis by promoting normal gut flora and preventing induction of interferon-gamma.
There are multiple mechanisms that protect the intestine from an excessive inflammatory response to intestinal microorganisms. We report here that all four mammalian peptidoglycan recognition… Expand

ATF4 activity: a common feature shared by many kinds of slow-aging mice
ATF4, a DNA‐binding factor that modulates responses to amino acid availability and ribosomal function, has been shown to be altered in both liver and fibroblasts from two strains of long‐lived mice,… Expand
