During fresh fruit consumption, sensory texture is one factor that affects the organoleptic qualities. Chemical components of plant cell walls, including pectin, cellulose, hemicellulose and lignin, play central roles in determining the textural qualities. To explore the genes and regulatory pathways involved in fresh citrus’ perceived sensory texture, we performed mRNA-seq analyses of the segment membranes of two citrus cultivars, Shiranui and Kiyomi, with different organoleptic textures.

Recent advances in bioimaging and automated analysis methods have enabled the large-scale systematic analysis of cellular dynamics during the embryonic development of Caenorhabditis elegans. Most of these analyses have focused on cell lineage tracing rather than cell shape dynamics.

Spectral imaging with polarity-sensitive fluorescent probes enables the quantification of cell and model membrane physical properties, including local hydration, fluidity, and lateral lipid packing, usually characterized by the generalized polarization (GP) parameter.

3D segmentation is often a prerequisite for 3D object display and quantitative measurements. Yet existing voxel-based methods do not directly give information on the object surface or topology.

Understanding the cellular architecture is a fundamental problem in various biological studies. C. elegans is widely used as a model organism in these studies because of its unique fate determinations. In recent years, researchers have worked extensively on C. elegans to excavate the regulations of genes and proteins on cell mobility and communication.

Histological features of renal arteries of goat revealed a typical muscular artery structure with three layers within outwards viz., tunica intima, media and adventitia. Abundant subendothelial connective tissue was limited by clear undulating internal elastic membrane. Tunica media in all three renal arterial segments i.e., proximal, middle and distal from aorta to the renal hilus was thicker. More than thirty rows of smooth muscle cells were arranged in circular fashion in tunica media. Their outer boundary was limited by fragmented thin wavy outer elastic membrane.

The present study was conducted on 24 Uttara fowl. The histological, histomorphometrical and histochemical features with their age related changes in large intestine were studied. The surface epithelium in both caeca and colorectum was lined by simple columnar epithelium with interspersed goblet cells. Finger like villous projections were seen in the tunica mucosa. PAS- Alcian blue reaction was showed by all the segments of caecum as well as colorectum.

In rod phototransduction, cyclic GMP synthesis by mem-brane bound guanylate cyclase ROS-GC1 is under Ca 2+ -dependent negative feedback control mediated by guanylate cyclase-activating proteins, GCAP-1 and GCAP-2. The cellular concentration of GCAP-1 and GCAP-2 approxi-mately sums to the cellular concentration of a functional ROS-GC1 dimer. Both GCAPs increase the catalytic effi-ciency (kcat /Km) of ROS-GC1. However, the presence of a myristoyl group in GCAP-1 has a strong impact on the regulation of ROS-GC1, this is in contrast to GCAP-2....

Báo cáo khóa học: High level cell-free expression and specific labeling of integral membrane proteins
We demonstrate the high level expression of integral membrane proteins (IMPs) in a cell-free coupled tran-scription/translation system using a modified Escherichia coli S30 extract preparation and an optimized protocol. The expression of theE. colismall multidrug transporters EmrE and SugE containing four transmembrane segments (TMS), the multidrug transporter TehA with 10 putative TMS, and the cysteine transporter YfiK with six puta-tive TMS, were analysed.

The functional and structural characterization of G-protein-coupled recep-tors (GPCRs) still suffers from tremendous difficulties during sample preparation. Cell-free expression has recently emerged as a promising alter-native approach for the synthesis of polytopic integral membrane proteins and, in particular, for the production of G-protein-coupled receptors.

The hexose transporter family, which mediates facilitated uptake in mammalian cells, consists of more than 10 members containing 12 mem-brane-spanning segments with a single N-glycosylation site. We previously demonstrated that glucose transporter 1 is organized into a raft-like deter-gent-resistant membrane domain but that glucose transporter 3 distributes to fluid membrane domains in nonpolarized mammalian cells.

Triatoma infestans(Hemiptera: Reduviidae) is a hematophagous insect that transmits the protozoan parasite Trypanosoma cruzi, the etiological agent of Chagas’ disease. Its saliva contains trialysin, a protein that forms pores in membranes. Peptides based on the N-terminus of trialysin lyse cells and fold into a-helical amphipathic segments resembling antimicrobial peptides. Using a specific antiserum against trialysin, we show here that trialysin is synthesized as a precursor that is less active than the protein released after saliva secretion. ...

Notch ligands are membrane-spanning proteins made of a large extracellu-lar region, a transmembrane segment, and a 100–200 residue cytoplasmic tail. The intracellular region of Jagged-1, one of the five ligands to Notch receptors in man, mediates protein–protein interactions through the C-ter-minal PDZ binding motif, is involved in receptor⁄ligand endocytosis trig-gered by mono-ubiquitination,

Abstract The interaction between prM and E proteins in flavivirus-infected cells is a major driving force for the assembly of flavivirus particles. We used site-directed mutagenesis to study the potential role of the transmembrane domains of the prM proteins of Japanese encephalitis virus (JEV) in prM-E heterodimerization as well as subviral particle formation.
