Flavonol-mediated stabilization of PIN efflux complexes regulates polar auxin transport

The transport of auxin controls the rate, direction and localization of plant growth and development. The course of auxin transport is defined by the polar subcellular localization of the PIN proteins, a family of auxin efflux transporters. However, little is known about the composition and regulation of the PIN protein complex. Here, using blue-native PAGE and quantitative mass spectrometry, we identify native PIN core transport units as homo- and heteromers assembled from PIN1, PIN2, PIN3, PIN4 and PIN7 subunits only. Furthermore, we show that endogenous flavonols stabilize PIN dimers to regulate auxin efflux in the same way as does the auxin transport inhibitor 1-naphthylphthalamic acid (NPA). This inhibitory mechanism is counteracted both by the natural auxin indole-3-acetic acid and by phosphomimetic amino acids introduced into the PIN1 cytoplasmic domain. Our results lend mechanistic insights into an endogenous control mechanism which regulates PIN function and opens the way for a deeper understanding of the protein environment and regulation of the polar auxin transport complex.

Codepositing Mussel-Inspired Nanohybrids onto One-Dimensional Fibers under “green” Conditions for Significantly Enhanced Surface/Interfacial Properties

Codeposition of a mussel-inspired nanohybrid coating was realized onto a carbon fiber (CF) surface via coincubation in a dopamine (DA) and octaammonium polyhedral oligomeric silsesquioxane (POSS-NH2) mixed aqueous solution. The deposition procedure was conducted under ambient conditions, and no harsh conditions and toxic solvents were needed. The surface morphologies, compositions, and energies of CFs were investigated. The interfacial shear strength (IFSS) was measured to demonstrate the interfacial combination and compatibility of fiber and epoxy resin, and the single-filament tensile strength (TS) was also determined to evaluate the damage degree brought by the modification procedure to the fiber intrinsic strength. As a result, the nanohybrid coating could greatly enhance surface wettability, interfacial compatibility, and interfacial mechanical strength and bring no deterioration to fiber intrinsic strength. Our facile strategy presents a promising platform to modify various one-dimensional fiber surfaces for advanced composite materials toward broadly mechanical-demanding and energy-saving usages.

Enhanced adhesion and differentiation of human mesenchymal stem cell inside apatite-mineralized/poly(dopamine)-coated poly(?-caprolactone) scaffolds by stereolithography

The purpose of this study is to develop PCL scaffolds using stereolithography technology and induced modifications using a poly dopamine (PDA)-coated/HA precipitate to stimulate human mesenchymal stem cells (hMSCs). The chemical composition and surface properties of HA/PDA/PLA were characterized by XPS. HA/PDA/PLA modulated hMSCs responses in several ways. The extracellular matrix (collagen and fibronectin) adsorption was significantly higher on the substrates with the highest amount of PDA coating than on pure PCL. Increased focal adhesion kinase (FAK) levels and enhanced cell attachment were observed upon an increase in PDA content. The proliferation, alkaline phosphatase, osteogenesis-related proteins (OPN and BSP), and angiogenesis-related protein (vWF and ang-1) secretion of hMSCs were significantly stimulated when the PDA-coated concentration was increased. The PDA-coated/HA precipitate increases osteogenesis and angiogenesis of hMSCs cultured with a PCL scaffold. Our results demonstrate that this simple, bio-inspired surface modification of the organic PCL scaffold using PDA is a very promising tool for regulating cell behaviour, and may serve as an effective stem cell delivery carrier for bone tissue engineering.

An electrochemical study of natural and chemically controlled eumelanin

Eumelanin is the most common form of the pigment melanin in the human body, with functions including antioxidant behavior, metal chelation, and free radical scavenging. This biopigment is of interest for biologically derived batteries and supercapacitors. In this work, we characterized the voltammetric properties of chemically controlled eumelanins produced from 5,6-dihydroxyindole (DHI) and 5,6-dihydroxyindole-2-carboxylic acid (DHICA) building blocks, namely, DHI-melanin, DHICA-melanin, and natural eumelanin, extracted from the ink sac of cuttlefish, Sepia melanin. Eumelanin electrodes were studied for their cyclic voltammetric properties in acidic buffers including Na+, K+, NH4+, and Cu2+ ions.

In silico approach of apoptosis induing ability of different indole derivatives by interaction with Caspase9

Indole compounds are well known for their wide variety of pharmacological activities. It is the combination of benzene with pyrrole ring. Compounds having indole group are biologically important. They are used as antimicrobial, antiviral, antituberular, anti-inflammatory, anticancer, ant-diabetic and anticonvulsant agents. Because of the wide variety of biological application, several substituted indole derivatives are studied for their molecular structure, molecular docking and bioavailability. The purpose of the study is to carry out the docking studies of indole derivatives containing electrophilic substitution and nucleophilic substitution with the anticancer target casp9. Fifty compounds were designed and by using Argus lab version 4.0.1. Their docking score was calculated and compared with the standard drug casodex. The drug likeness of compounds were performed using Lipinski rule of five. Result showed that 1,1?-(1H-indole-5,6-diyl)diethanone and 5-(trichloromethyl)-1H-indole and the phytoconstituent curcumin showed better docking score than that of the standard drug casodex. It is concluded that certain indole derivatives show greater affinity with casp9 protein. These compounds may be helpful in studying anticancer targets for casp9 protein.

A study on beta-glucan binding protein (beta-GBP) and its involvement in phenoloxidase cascade in Indian white shrimp Fenneropenaeus indicus

The present study reports the purification of novel immune molecule beta-1, 3 glucan binding protein from the heamolymph of the Indian white shrimp, Fenneropenaeus indicus (Fibeta-GBP). The purified Fibeta-GBP had 95 kDa molecular weight in SDS-PAGE analysis. MALDI-TOF/TOF analysis revealed that the purified Fibeta-GBP showed similarity to various crustacean proteins; 48 and 46% similarity was observed for beta-1, 3 glucan binding protein of Chinese white shrimp Fenneropenaeus chinensis and banana shrimp Fenneropenaeus merguiensis, with MOWSE score of 3.11e + 12 and 2.05e + 8, respectively. The phenoloxidase activity (PO) of Fibeta-GBP was evaluated and, in the presence of laminarin, PO activity increased significantly. Substrate specificity assay demonstrated that Fibeta-GBP had the specific binding site for soluble or insoluble beta-glucan (laminarin), since the PO activity increased in the presence of laminarin when compared to other sugars. Enzymatic activities revealed that the optimum temperature and pH for Fibeta-GBP activating PO were 40 C and pH 7?8. Moreover, even at 100 C Fibeta-GBP enhanced PO activity highlighting that Fibeta-GBP was thermostable and thermophilic in nature. Among various divalent metallic ions, Fibeta-GBP significantly promoted the PO activity in presence of Mg2+ and Ca2+. The breakdown of para nitroanilide from Nalpha?Benzoyl-L-Arginine 4-Nitroanilide hydrochloride showed that serine protease activity was induced by Fibeta-GBP and also increased concentration of Fibeta-GBP evoked the activity. Furthermore, hemolytic activity tests revealed that PO reaction product induced RBC membrane damage and cell shrinkage. Lastly, Baclight bacterial viability assays showed maximum killing effect of PO reaction product on both Gram positive and Gram negative bacteria.

Determination of eumelanin and pheomelanin in melanomas using solid-phase extraction and high performance liquid chromatography?diode array detection (HPLC-DAD) analysis

Determination of eumelanin and pheomelanin in melanomas that exhibit different pigmentation was carried using a solid-phase extraction (SPE) preparation method based on weak anion exchange chemistry. This extraction significantly enhanced the chromatographic profile obtained by reverse phase high performance liquid chromatography-diode array detection (RP-HPLC-DAD). The SPE method was developed using aqueous standards of melanin markers: thiazole-2,4,5-tricarboxylic acid (TTCA), thiazole-4,5-dicarboxylic acid (TDCA), pyrrole-2,3-dicarboxylic acid (PDCA) and pyrrole-2,3,5-tricarboxylic acid (PTCA) and non-pigmented cell lines spiked with those markers. An excellent average recovery, above 90%, was obtained for the four markers with a relative standard deviation below 7%. We have also optimized the stationary phase and the mobile phase (phosphate concentration and pH) to improve sensitivity and to reduce the analysis time. Elution of the four markers is achieved in 5 min and total analysis of biological samples is completed in 15 min. The quantification limits for TDCA, TTCA, PDCA and PTCA are 60, 50, 47 and 48 ng/mL respectively. Furthermore, DAD detection improves the marker identification in complex matrices through the analysis of UV spectra. We have successfully applied this method to melanoma tumors and cells. Murine B16BL6 tumor are highly pigmented with mostly eumelanin (98.1% of eumelanin) while human SK-MEL-3 tumor contain about 30% pheomelanin. B16BL6 and B16F10 are eumelanic cells lines and NHEM melanocytes contain about 24% of pheomelanin.

Kinetics of Melanin Polymerization during Enzymatic and Nonenzymatic Oxidation

Melanin is an abundant biopigment in the animal kingdom, but its structure remains poorly understood. This is a substantial impediment to understanding the mechanistic origin of its observed functions. Proposed models of melanin structure include aggregates of both linear and macrocyclic units and noncovalently held monomers. Both models are broadly in agreement with current experimental data. To constrain the structural and kinetic models of melanin, experimental data of high resolution with chemical specificity accompanied by atomistic modeling are required. We have addressed this by obtaining electronic absorption, infrared, and ultraviolet resonance Raman (RR) spectra of melanin at several wavelengths of excitation that are sensitive to small changes in structure. From these experiments, we observed kinetics of the formation of different species en route to melanin polymerization. Exclusive chemical signatures of monomer 3,4-dihydroxyphenylalanine (dopa), intermediate dopachrome (DC), and early-time polymer are established through their vibrational bands at 1292, 1670, and 1616 cm-1 respectively. Direct evidence of reduced heterogeneity of melanin oligomers in tyrosinase-induced formation is provided from experimental measurements of vibrational bandwidths. Models made with density functional theory show that the linear homopolymeric structures of 5,6-dihydroxyindole can account for experimentally observed wavenumbers and broad bandwidth in Raman spectra of dopa-melanin. We capture resonance Raman (RR) signature of DC, the intermediate stabilized by the enzyme tyrosinase, for the first time in an enzyme-assisted melanization reaction using 488 nm excitation wavelength and propose that this wavelength can be used to probe reaction intermediates of melanin formation in solution.
