ProteomicsAedes aegypti mosquito eggshell proteins in response to RNAi-EOF1
Aedes aegypti mosquito ovarian follicles develop synchronously after taking a blood meal. A single layer of follicular epithelial cells surrounding the oocyte is responsible for secreting a majority of eggshell structural components between 18 and 54 hours post blood meal. We previously identified a...

ProteomicsXitou site Eggshell Samples LC-MS/MS
This project focuses on the proteomic analysis of Xitou eggshell samples using high-resolution LC-MS/MS. The primary goal is to identify and characterize the protein components, evaluate their post-translational modifications, and compare them with modern goose eggshell proteomes. The results aim to...

ProteomicsAncient proteins resolve controversy over the identity of Genyornis eggshell
Here we show the potential of proteins preserved in Pleistocene eggshell for addressing a longstanding controversy in human and evolution: the identity of the extinct bird that laid the eggs which were exploited by Australia’s first inhabitants. The eggs had been originally attributed to the iconic ...

ProteomicsMineral-bound ostrich eggshell peptides survive for up to 3.8 Ma in equatorial Africa
Claims for exceptional preservation of biomolecules in the fossil record are contested. Here we demonstrate the role of surface stabilisation in significantly prolonging protein sequence survival to ~3.8 million years. The intracrystalline environment of calcite ostrich (Struthionidae) eggshell enca...

ProteomicsCharacterization and quantification of chicken eggshell proteins during pivotal events of shell calcification
Gallus gallus avian eggshell is composed of 95% calcium carbonate on calcitic form and of 3.5% extracellular organic matrix (proteins, polysaccharides and proteoglycans). This highly ordered structure with a polycrystalline organization result of the control of mineral deposition by the organic matr...

cDNA microarrays were used to identify the expression of the genes in uterus by comparison with two others regions of the oviduct not involved in the shell deposition. A total of 605 sequences specifically over-expressed were revealed. The expression of 15 of them was also confirmed using qRT-PCR, a...

ProteomicsOstrich eggshell peptides survival into the Miocene (6-9 Ma)
The oldest authenticated peptide sequences to date were reported in 2016 from 3.8 Ma old ostrich eggshell (OES) from the site of Laetoli, Tanzania (Demarchi et al., 2016). Here we demonstrate survival of the same sequences in 6.5-9Ma OES recovered from a palaeosteppe setting in northwestern China. T...
