Abstract Aliphatic alcohols naturally exist in many organisms as important cellular components; however, their roles extracellular polymer biosynthesis are poorly defined. We report here the isolation and characterization of a rice (Oryza sativa) male-sterile mutant, defective pollen wall (dpw), which displays anther development degenerated grains with an irregular exine. Chemical analysis revealed that dpw anthers had dramatic reduction cutin monomers altered composition cuticular wax, well...

Pesticide residues are a global threat to human health, and conventional sensors fail simultaneously detect pesticide on the surface inside agricultural products. In this work, we present new microneedle (MN) patch-based surface-enhanced Raman spectroscopy (SERS) sensor. The needles basement of MNs can Ag nanoparticles sodium hyaluronate/poly(vinyl alcohol) (HA/PVA) hydrogel used in MN sensor efficiently amplify signals residues. addition, HA/PVA effectively quickly collect residues,...

Studies on hypoxia-sensitive pathways have revealed a series of Fe(II)-dependent dioxygenases that regulate hypoxia-inducible factor (HIF) by prolyl and asparaginyl hydroxylation. The recognition these unprecedented signaling processes has led to search for other substrates the HIF hydroxylases. Here we show human hydroxylase, inhibiting (FIH), also efficiently hydroxylates specific (Asn)-residues within proteins IkappaB family. After identification ankyrin repeat domain (ARD)-containing in...

Abstract Male Sterile2 (MS2) is predicted to encode a fatty acid reductase required for pollen wall development in Arabidopsis (Arabidopsis thaliana). Transient expression of MS2 tobacco (Nicotiana benthamiana) leaves resulted the accumulation significant levels C16 and C18 alcohols. Expression fused with green fluorescent protein revealed that an amino-terminal transit peptide targets plastids. The plastidial localization biologically important because genetic complementation ms2 homozygous...

Suberin, a polyester polymer in the cell wall of terrestrial plants, controls transport water and nutrients protects plant from pathogenic infections environmental stresses. Structurally, suberin consists aliphatic aromatic domains; p-hydroxycinnamates, such as ferulate, p-coumarate, and/or sinapate, are major phenolic constituents latter. By analyzing "wall-bound" phenolics mutant lines Arabidopsis deficient family acyl-CoA dependent acyltransferase (BAHD) genes, we discovered that...

Abstract Pectin is a major component of the primary cell wall higher plants. Some galacturonyl residues in backbone pectinaceous polysaccharides are often O-acetylated at C-2 or C-3 position, and resulting acetylesters change dynamically during growth development The processes involve both enzymatic acetylation deacetylation. Through genomic sequence analysis, we identified pectin acetylesterase (PAE1) from black cottonwood (Populus trichocarpa). Recombinant Pt PAE1 exhibited preferential...

Acute leukemia is currently the major cause of death in hematological malignancies. Despite rapid development new therapies, minimal residual disease (MRD) continues to occur and leads poor outcomes. The niche bone marrow microenvironment (BMM) thought be responsible for such MRD development, which can lead drug resistance relapse. Consequently further investigation into way interacts with acute cells (ALCs) strategies block underlying process are expected improve prognosis. Recent studies...

Titanium dioxide nanoparticles (TiO2 NPs) have been used in various medical and industrial areas. However, the impacts of these on neuroinflammation brain are poorly understood. In this study, mice were exposed to 2.5, 5, or 10 mg/kg body weight TiO2 NPs for 90 consecutive days, TLRs/TNF-α/NF-κB signaling pathway associated with hippocampal was investigated. Our findings showed titanium accumulation hippocampus, impairment spatial memory following exposure NPs. Furthermore, significantly...

Biologically produced alkanes represent potential renewable alternatives to petroleum-derived chemicals. A cyanobacterial pathway consisting of acyl–Acyl Carrier Protein reductase and an aldehyde-deformylating oxygenase (ADO) converts Proteins into corresponding n-1 via aldehyde intermediates in oxygen-dependent manner (K m for O 2 , 84 ± 9 µM). In vitro, ADO turned over only three times, but addition more exhausted assays resulted additional product formation. While evaluating the peroxide...

Novel tricyclic benzimidazole carboxamide poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors have been synthesized. Several compounds were found to be powerful chemopotentiators of temozolomide and topotecan in both A549 LoVo cell lines. In vitro inhibition PARP-1 was confirmed by direct measurement NAD+ depletion ADP-ribose polymer formation caused chemically induced DNA damage.

Abstract Plant metacaspases mediate programmed cell death in development, biotic and abiotic stresses, damage-induced immune response, resistance to pathogen attack. Most require Ca 2+ for their activation substrate processing. However, the -dependent mechanism remains elusive. Here we report crystal structures of Metacaspase 4 from Arabidopsis thaliana ( At MC4) that modulates -dependent, plant defense. The MC4 structure exhibits an inhibitory conformation which a large linker domain blocks...
