Project description:Mussels synthesize an interesting class of biological materials with unique properties to adhere onto virtually any solid surface. Inter- and cross-species analyses have revealed that mussel byssus fabrication is influenced by environmental factors. In this study, proteins expressed specifically byssus and in the byssal-producing organ (foot) were examined for two mussel species from the Mytilidae family using liquid chromatography coupled with high-resolution tandem mass spectrometry (LC-MS/MS). The main goal was to describe which proteins are exclusively expressed in the mussel's foot gland, which is responsible for byssus secretion. Proteins uniquely found in the foot samples have been found by comparing to a control tissue (mantle). The overlap with proteins found in byssus samples were also investigated. A restricted list of these proteins have been highlighted as byssus-related, believed to contribute to the unique properties of byssus, such as securing adhesion and toughness, and plasticity based on environmental factors (including promoter regulation). This work may provide further directions on thread biofabrication and additional information on its regulation, as well as contribute to a more complete description of the mussel proteome.

Project description:Many bivalve species produce groups of strong proteinaceous byssal threads to rigidly attach to underwater substrates. Fibres like these have potential applications as biomedical materials due to their unique mechanical characteristics. The byssus and byssal thread producing glands of Pinctada maxima have not yet been characterised. RNA was isolated from P. maxima foot and byssal stem region tissues and sequenced using the Illumina platform. A de novo reference transcriptome comprising 34,281 contiguous sequences was assembled, and tissue replicates were mapped against the reference for quantitative analysis. Tryptic digests of byssal threads were analysed by LC-MS/MS. The resultant peptides were matched to 62 protein sequences derived from our reference transcriptome. Components of the byssus were identified for further characterisation, including a highly expressed perlucin-like foot protein (Pmfp1) and a recently identified protein that we refer to herein as glycine-rich thread (GRT) protein. This work provides principal knowledge on the molecular components of the byssus for P. maxima and the foot ultrastructure involved in the creation of byssal threads. This study advances our knowledge of byssus biosynthesis in non-mytilids, providing a platform for the design of new marine biopolymers.

Project description:Factorial Microarray Analysis of Zebra Mussel (Dreissena polymorpha) Adhesion Process under the Impact of Multiple Environmental Factors The expression profiles of the zebra mussel byssus unique genes in our cDNA microarray can be influenced by multiple factors. Three environmental factors plus adhesion status were considered as four main factors in this study.

Project description:Factorial Microarray Analysis of Zebra Mussel (Dreissena polymorpha) Adhesion Process under the Impact of Multiple Environmental Factors The expression profiles of the zebra mussel byssus unique genes in our cDNA microarray can be influenced by multiple factors. Three environmental factors plus adhesion status were considered as four main factors in this study. Two different levels in each factor were created, therefore, a 2x2x2x2 factorial experimental design was made by sixteen treatment groups with four biological replicates in each group. There were 32 dual-channel microarray slides included in this study and the effects of main factors on gene expression profiles as well as the two-way, three-way, and four-way interactions of the main factors were analyzed. Factors: temperature, water agitation, oxygen level, and adhesion status

Project description:Gene expression changes in human populations exposed to chronic low level radiation have important implications. There are few areas around the world where human population is exposed to elevated levels of natural background radiation. The high level natural radiation areas (HLNRAs) of Kerala coast in south west India is unique for its wide variation in the background radiation dose (<1.0mGy to 45mGy/year). The areas with a background radiation dose of ≤ 1.5mGy/year are considered as normal level natural radiation areas (NLNRA), whereas areas with > 1.5mGy/year are considered as HLNRA. We used microarray analysis to find out global changes in gene expression in peripheral blood mononuclear cells (PBMCs) of individuals belonging to different HLNRA groups as compared to individuals from normal level natural radiation areas (NLNRA).
