One species in eight: DNA barcodes from type specimens resolve a taxonomic quagmire

Molecular Ecology Resources, 2015
AbstractEach holotype specimen provides the only objective link to a particular Linnean binomen. Sequence information from them is increasingly valuable due to the growing usage of DNA barcodes in taxonomy. As type specimens are often old, it may only be possible to recover fragmentary sequence information from them.

Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

Molecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

DNA barcoding reveals a taxonomic fraud: Note on validity of Propomacrus muramotoae (Coleoptera, Scarabaeidae) [PDF]

ZooKeys
Until the early 2000s, the genus Propomacrus was known to comprise two species, occurring in the Eastern Mediterranean and Southeast China. The discovery of Propomacrus muramotoae Fujioka in Tibet and subsequently in Bhutan and Nepal, might play a crucial role in bridging the geographical distribution gap of the Euchirini tribe between the ...

Highlighting Astyanax Species Diversity through DNA Barcoding. [PDF]

PLoS ONE, 2016
DNA barcoding has been used extensively to solve taxonomic questions and identify new species. Neotropical fishes are found in a wide variety of shapes and sizes, with a large number of species yet to be described, many of which are very difficult to ...

Sampling Local Fungal Diversity in an Undergraduate Laboratory using DNA Barcoding [PDF]

, 2014
Traditional methods for fungal species identification require diagnostic morphological characters and are often limited by the availability of fresh fruiting bodies and local identification resources.

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma

Molecular Oncology, EarlyView.
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Crucial parameters for precise copy number variation detection in formalin‐fixed paraffin‐embedded solid cancer samples

Molecular Oncology, EarlyView.
This study shows that copy number variations (CNVs) can be reliably detected in formalin‐fixed paraffin‐embedded (FFPE) solid cancer samples using ultra‐low‐pass whole‐genome sequencing, provided that key (pre)‐analytical parameters are optimized.

DNA barcoding of plants: Selection of core markers for taxonomic groups

Plant Science Today, 2017
Plant identification is a crucial and routine taxonomic procedure in order to understand and conserve the biodiversity. Anthropogenic activity, pollution, deforestation, and exploitation of natural resources have been threatening to the plant biodiversity.
