Medieval birth girdle stains LC-MSMS

ABSTRACT: This project applied a dry non-invasive method to detect palaeoproteomic evidence from stained manuscripts. The manuscript analysed in this study is a medieval parchment birth girdle (Wellcome Collection Western MS. 632) made in England and thought to be used by pregnant women while giving birth. Using a dry non-invasive sampling method we were able to extract both human and non-human peptides from the stains, including evidence for the use of honey, cereals, ovicaprine milk and legumes. In addition, a large number of human peptides were detected on the birth roll, many of which are found in cervico-vaginal fluid. This suggests that the birth roll was actively used during childbirth. This study is the first to extract and analyse non-collagenous peptides from a parchment document using a dry non-invasive sampling method and demonstrates the potential of this type of analysis for stained manuscripts, providing direct biomolecular evidence for active use.

In this paper, we describe palaeoproteomic evidence obtained from a stained medieval birth girdle using a previously developed dry non-invasive sampling technique. The parchment birth girdle studied (Wellcome Collection Western MS. 632) was made in England in the late fifteenth century and was thought to be used by pregnant women while giving birth. We were able to extract both human and non-human peptides from the manuscript, including evidence for the use of honey, cereals, ovicaprine milk and ...[more]

Project description:Fission yeast cells undergo sexual differentiation in response to nitrogen starvation. In this process haploid M and P cells first mate to form diploid zygotes, which subsequently enter meiosis and sporulate. Prior to mating, M cells secrete M-factor and P-cells secrete P-factor, and these diffusible mating pheromone can activate a signal transduction pathway in the opposite cell type. The pheromone response orchestrates mating and is also required for entry into meiosis. Here we use DNA microarrays to identify genes that are induced by M-factor in P cells and by P-factor in M-cells. The use of a cyr1 genetic background allowed us to study pheromone stimulation independently of nitrogen starvation. We identified a total of 163 genes that were consistently induced more than two-fold by pheromone stimulation. As expected, there was a substantial overlap between the genes induced by M- and P-factor. Surprisingly, we found that pheromone control extended to genes fulfilling their function well beyond the point of entry into meiosis, including numerous genes required for meiotic recombination. A direct comparison of the M- and P-factor induced expression pattern allowed us to identify cell-type specific transcripts, including three new M-specific genes and one new P-specific gene. Finally, our results support the notion that Ste11 is the key transcription factor activated by pheromone signalling. Keywords: dose response Gene expression profiling experiment in which gene expression in pheromone treated cultures was compared to that of untreated control cells. All cultures were growing exponentially in MSL minimal medium. S. pombe h+ cyr1- cells treated with M-factor mating pheromone for 2, 4 and 6 hrs respectively, were compared to non-treated cells. Similarly, S. pombe h- sax2- cyr1- cells treated with P-factor mating pheromone for 2, 4 and 6 hrs, were compared to non-treated cells. For identiofication of cell-type specific gene expression, h+ cyr1- cells were compaired to h+ sxa2- cyr1- cells. This was done both before pheromone treatment (0h/0h) and after 6 hours of pheromone treatment (6h/6h). RNA was extracted and subjected to cDNA expression profiling analysis using the established protocols (Xue et al, Yeast 21, 25-39, 2004).Data normalized with 'Lowess' per chip per spot normalization.
