Project description:Microbial communities of dental calculus from 100+ year-old human remains in Milwaukee, WI USA
| PRJNA818350 | ENA
Project description:Archaeological dental calculus has emerged as a rich source of ancient biomolecules, including proteins. Previous analyses of proteins extracted from ancient dental calculus revealed the presence of the dietary milk protein β-lactoglobulin, providing direct evidence of dairy consumption in the archaeological record. However, the potential for calculus to preserve other food-related proteins has not yet been systematically explored. Here we analyse shotgun metaproteomic data from 100 archaeological dental calculus samples ranging from the Iron Age to the post-medieval period (8thC BC - 19thC AD) in Britain, as well as dental calculus from contemporary dental patients and recently deceased individuals, to characterise the range and extent of dietary proteins preserved in dental calculus. In addition to milk proteins, we detected proteomic evidence of foodstuffs such as cereals and plant products, as well as the digestive enzyme salivary amylase. We discuss the importance of optimized protein extraction methods, data analysis approaches, and authentication strategies in the identification of dietary proteins from archaeological dental calculus. Our ability to detect dietary proteins, although limited, demonstrates the potential of these methods to robustly identify foodstuffs in the archaeological record that are under-represented due to their poor preservation.

Project description:We report the application of RNA sequencing technology for high-throughput profiling of gene expression in YAP2SA-lentivirus-infected adult human dental pulp stromal cells (hDPCs).To overexpress YAP2SA in hDPCs we transfected cells with YAP2SA-lentivirus. Cells were derived from a 18~22-year-old healthy male human donor. Total mRNA was collected using TRIzol ® (Invitrogen, CA, USA) solution. Then all the extraction procedures were conducted according to manufacture’s instructions for RNA extraction from homogenized tissues. After quality checks they were subjected to the high-throughput RNA-sequencing. Every group consists of 3 replicates which were from 3 independent experimental repeats.

Project description:Ancient human dental calculus Metagenome
| PRJNA608541 | ENA
Project description:The purpose of this study was to investigate oral microbiome and host proteins in archaeological human dental tissues using a shotgun proteomics approach. The research focuses on dental calculus (mineralized plaque), dentine, a carious lesion, and an alveolar bone abscess from the medieval site of Dalheim, Germany (ca. AD 950-1200). For comparison, proteins were also analyzed from archaeological faunal dental tissues and human dental calculus samples from modern Swiss dental patient controls. Protein extraction and generation of tryptic peptides from tooth and dental calculus specimens was performed using a filter-aided sample preparation (FASP) protocol, modified for mineralized and degraded samples. Total protein extraction was performed on a total of fourteen samples: four ancient human calculus samples (indicated as: G12, B71, B61, and B78), four ancient human tooth root samples (indicated as: G12, B17, B61, and B78), one carious lesion (indicated as: B17), one alveolar bone abscess (indicated as: B17), two ancient fauna crown cementum/calculus samples (indicated as: F1 [sheep] and F5 [cattle]), and two modern dental calculus samples from clinical patients (indicated as: P1 and P2). All samples were extracted at the Centre for Evolutionary Medicine (ZEM) at the University of Zürich with the exception of dental calculus from G12, P1, and P2, which were extracted at the Center for GeoGenetics (CGG) at the University of Copenhagen. Two samples (G12 and B61 calculus) were extracted a second time in an independent laboratory at the University of York (YORK) for comparison. Sample extracts were then sequenced (LC-MS/MS) at the Functional Genomics Center Zürich (FGCZ) using an LTQ-Orbitrap Velos, at the Novo Nordisk Foundation Center for Protein Research (CPR) using a Q-Exactive Hybrid Quadrupole Orbitrap, and at the University of York’s Proteomics and Analytical Biochemistry Laboratories (PABL) using a MaXis UHR-Qq-TOF.

Project description:We report the application of RNA sequencing technology for high-throughput profiling of gene expression in YAP knockdown (siYAP) adult human dental pulp stromal cells (hDPCs).To knockdown YAP in hDPCs we transfected cells with YAP specific siRNAs and the scrambled RNAs. Cells were derived from a 18~22-year-old healthy male human donor. To induce pulp inflammation we used LPS to treat cells. Total mRNA was collected using TRIzol ® (Invitrogen, CA, USA) solution. Then all the extraction procedures were conducted according to manufacture’s instructions for RNA extraction from homogenized tissues. After quality checks they were subjected to the high-throughput RNA-sequencing. Every group consists of 2 replicates which were from 2 independent experimental repeats.

Project description:Mineralised dental plaque (calculus) has proven to be an excellent source of ancient biomolecules. In this study we present a Mycobacterium leprae genome (6.6-fold), the causative agent of leprosy, recovered via shotgun sequencing of 16th century human dental calculus from an individual from Trondheim, Norway. Moreover, ancient mycobacterial peptides were retrieved via mass spectrometry-based proteomics, further validating the presence of the pathogen. M. leprae can readily be detected in the oral cavity and associated mucosal membranes, which likely contributed to it being incorporated into this individual’s dental calculus. This individual showed some possible, but not definitive, evidence of skeletal lesions associated with early stage leprosy. This study is the first known example of successful multi-omics retrieval of M. leprae from archaeological dental calculus. Furthermore, we offer new insights into dental calculus as an alternative sample source to bones or teeth for detecting and molecularly characterizing M. leprae in individuals from the archaeological record.

Project description:Prolific heterotrophic biofilm growth is a common occurrence in airport receiving streams containing deicer and anti-icer runoff. This study investigated relations of heterotrophic biofilm prevalence and community composition to environmental conditions at stream sites upstream and downstream of Milwaukee Mitchell International Airport in Milwaukee, WI, during two deicing seasons (2009–2010 and 2010–2011). Modern genetic tools (such as microarray) have not previously been applied to biofilm communities in this type of setting. We used microarray results to characterize biofilm community composition as well as the response of the biofilm community to environmental factors (i.e., organic content (using chemical oxygen demand concentration) and temperature).
