Latest genotyping technologies allow to achieve a reliable genetic profile for the offender identification even from extremely minute biological evidence. The ultimate challenge occurs when genetic profiles need to be retrieved from a mixture, which is composed of biological material from two or more individuals. In this case, DNA profiling will often result in a complex genetic profile, which is then subject matter for statistical analysis. In principle, when more individuals contribute to a mixture with different biological fluids, their single genetic profiles can be obtained by separating the distinct cell types (e...

The oviductal epithelium is crucial for the integrity of the female organ. Previously we got evidence that the surface proteome of oviductal epithelial cells (Oecs) is promptly altered in response to insemination and thus suggested that this early phase plays a notable regulatory role in maintaining cellular function. This study further aimed to assess the effect of semen on the cellular and molecular mechanisms in rabbit Oecs. A quantitative gel-based proteomic approach was applied to analyze changes at three time points (0h, 1h, 2h) after intrauterine insemination (IUI) compared to time matched controls...

DNA methylation patterns have the ability to reveal the activities of genes within a certain tissue at a particular time point. Tissue-specific DNA methylation patterns have been previously investigated for their applicability in the identification of forensically relevant body fluids, however there is still a lack in robust markers. While following a genome-wide scale investigation has a great potential to reveal useful tissue-specific changes, a gene-targeted approach can also lead to significant outcomes, especially in genomic locations not included in the genome-wide experiments...
