Epigenetics of Ancient DNA [PDF]

open access: yesActa Naturae, 2016
Initially, the study of DNA isolated from ancient specimens had been based on the analysis of the primary nucleotide sequence. This approach has allowed researchers to study the evolutionary changes that occur in different populations and determine the influence of the environment on genetic selection.

A quantitative approach to detect and overcome PCR inhibition in ancient DNA extracts

open access: yesBioTechniques, 2009
Inhibition is problematic in many applications of PCR, particularly those involving degraded or low amounts of template DNA, when simply diluting the extract is undesirable. Two basic approaches to monitoring inhibition in such samples using real-time or

Preferential access to genetic information from endogenous hominin ancient DNA and accurate quantitative SNP-typing via SPEX [PDF]

open access: yes, 2009
The analysis of targeted genetic loci from ancient, forensic and clinical samples is usually built upon polymerase chain reaction (PCR)-generated sequence data.

Molecular Identification of Bacteria by Total Sequence Screening: Determining the Cause of Death in Ancient Human Subjects [PDF]

open access: yes, 2011
Research of ancient pathogens in ancient human skeletons has been mainly carried out on the basis of one essential historical or archaeological observation, permitting specific pathogens to be targeted.

Apolipoprotein E (APOE) Haplotypes in Healthy Subjects from Worldwide Macroareas: A Population Genetics Perspective for Cardiovascular Disease, Neurodegeneration, and Dementia

open access: yesCurrent Issues in Molecular Biology, 2023
Human APOE is a 299-amino acid long protein expressed and secreted in several tissues and body districts, where it exerts different functions mainly related to lipid metabolism, with specific activities around cholesterol transport and absorption ...

Microbiome applications for pathology: challenges of low microbial biomass samples during diagnostic testing

open access: yesThe Journal of Pathology: Clinical Research, 2020
The human microbiome can play key roles in disease, and diagnostic testing will soon have the ability to examine these roles in the context of clinical applications.

Indigenous sex-selective salmon harvesting demonstrates pre-contact marine resource management in Burrard Inlet, British Columbia, Canada

open access: yesScientific Reports, 2021
To gain insight into pre-contact Coast Salish fishing practices, we used new palaeogenetic analytical techniques to assign sex identifications to salmonid bones from four archaeological sites in Burrard Inlet (Tsleil-Waut), British Columbia, Canada ...

Surveying the repair of ancient DNA from bones via high-throughput sequencing

open access: yesBioTechniques, 2015
DNA damage in the form of abasic sites, chemically altered nucleotides, and strand fragmentation is the foremost limitation in obtaining genetic information from many ancient samples. Upon cell death, DNA continues to endure various chemical attacks such
