Simple Strategy of Integrating the Micro-centrifugation-based Extraction and 4-Hexylphenylazosulfonate for the Preparation of Plant Microsomal Proteins for Bottom-Up Proteomics

ABSTRACT: The preparation of high-quality microsomal proteins (MPs) is of critical importance to high-throughput microsomal proteomics. The isolation of MPs for proteomic analysis has to date relied on Ultracentrifugation-based methods (UBMs), however, these methods are labor-intensive, time-consuming, and unaffordable to many laboratories. Here, we report a simple method developed by integrating the micro-centrifugation-based extraction (MME) method and 4-hexylphenylazosulfonate (Azo) surfactant for the isolation and solubilization of MPs from rice leaves. A mass spectrometry-based (MS) label-free proteomic approach was used for a comprehensive quantitative comparison of the extractability between the MME method and the plasma membrane extraction (PME) kit and of the ability to solubilize proteins between Azo and sodium dodecyl sulfate (SDS). Results showed that the MME method can not only effectively isolate MPs from rice leaves for a bottom-up proteomic analysis but also performs better than the PME kit in the enrichment of plasma membrane (PM) proteins. Additionally, Azo was found to effectively solubilize total proteins, including the MPs from rice leaves for bottom-up proteomics with performance comparable to that of SDS. Azo can be integrated with the MME approach as a simple and effective strategy to prepare MPs and could replace SDS for high-throughput proteomic studies. This is the first study revealing the applicability of the micro-centrifugation-based method and Azo in plant proteomics

The preparation of microsomal membrane proteins (MPs) is critically important to microsomal proteomics. To date most research studies have utilized an ultracentrifugation-based approach for the isolation and solubilization of plant MPs. However, these approaches are labor-intensive, time-consuming, and unaffordable in certain cases. Furthermore, the use of sodium dodecyl sulfate (SDS) and its removal prior to a mass spectrometry (MS) analysis through multiple washing steps result in the loss of ...[more]

Project description:Schistosomiasis, caused by infection with Schistosoma trematode parasites, is one of the deadliest neglected tropical diseases in the world. The Schistosoma lifecycle involves the miracidia infection of an intermediate molluscan host, such as Biomphalaria glabrata. Dispersing B. glabrata attractant chemicals has been considered a method of minimising host infections. The attractiveness of B. glabrata is known to be reduced following infection; however, it remained unclear how the duration of infection affects attractiveness. Identifying excretory-secretory proteins (ESPs) abundant in attractive snail conditioned water (SCW) may facilitate the identification of attractants. This study obtained SCW ESPs from naïve snails and at different time-points post-miracidia exposure (PME; 16h-, 1 week, 2 weeks and 3 weeks), to identify those ESPs mediating Schistosome mansoni miracidia behavioural changes. The ESPs were quantitatively identified from all SCW samples using a label-free proteomic method and genome-derived protein databases of B. glabrata and S. mansoni. We found that changes in miracidia behaviour were similar upon exposure to naïve and 3W-PME SCW, including increased circling and quantity of miracidia in the field of view. Of the ESPs identified, 21 were shared in SCW of naïve and 3W-PME, and considered attractant candidates, including acetylcholine-binding protein and immune-related proteins such as biomphalysins and thioester-containing protein 1. Some biological processes were exclusive to attractant candidates, including obsolete pathogenesis and transmembrane transport activity. This suggests that compromised production of these proteins may diminish host attractiveness to miracidia. Additionally, several immune proteins were identified exclusively at 16-PME and 1W-PME, providing further information into changing B. glabrata immune responses throughout infection. These findings provide a list of attractant candidates to potentially decrease B. glabrata infection and minimise schistosomiasis.

Project description:Understanding the way in which the airway heals in response to injury is fundamental to dissecting the mechanisms underlying airway disease pathology. Only limited data is available in relation to in vivo characterisation of the molecular features of repair in the airway. This study sought to characterise the dynamic changes in gene expression that are associated with airway repair in response to physical injury. Gene expression changes in the airway wall following bronchial brush biopsy were profiled in anaesthetised sheep. The experimental design featured sequential studies in the same animals (n=8) over the course of a week and yielded data relating to the repair process at 6 hours, and 1, 3 and 7 days after injury. Notable features of the transcriptional response included the early and sustained preponderance of down-regulated genes associated with angiogenesis and immune cell activation, selection and differentiation. Later features of the repair response included the up-regulation of cell cycle genes at d1 and d3, and the later pronounced up-regulation of extracellular matrix-related genes at d3 and d7. It is possible to follow the process of airway wall repair in response to physical injury in the same animal over the course of time. Transcriptional changes featured coordinate expression of functionally related genes in a reproducible manner both within and between animals. This characterisation will provide a foundation against which to assess the perturbations that accompany airway disease pathologies of comparative relevance. Keywords: response to airway injury Each sheep was subjected to a protocol which involved the procedure of endobronchial brush biopsy (BBr) being performed, under anaesthesia, on three occasions, with two separate airway sites being subjected to brushing on each occasion. Two sheep were subjected to BBr seven days, three days and six hours prior to euthanasia, two sheep at seven days, three days and one day prior to euthanasia, two sheep at seven days, one day and six hours prior to euthanasia and two sheep at three days, one day and six hours prior to euthanasia. At post mortem examination (PME) each time point was therefore represented by material derived from six sheep. Airway tissue from a naM-CM-/ve site (from a segment not subjected to BBr) was also collected from each sheep at necropsy.
