A qPCR Assay for the Threatened Pilbara Olive Python (Liasis olivaceus barroni)

open access: yesEnvironmental DNA
The Pilbara olive python (Liasis olivaceus barroni) is endemic to the Pilbara region of Western Australia and listed as threatened. Despite being a priority conservation target, they are difficult to monitor as their cryptic nature complicates ...

Identification of orb-web spider species and their food source through environmental DNA analysis

open access: yesJournal of Ecology and Environment
Spiders play a vital role in agricultural ecosystems by capturing and preying on small insects, thereby controlling the pests around crops. However, without directly collecting the specimen, it is challenging to accurately determine the species of the ...

Bridging the gap: Multi‐stakeholder perspectives of molecular diagnostics in oncology

open access: yesMolecular Oncology, EarlyView.
Although molecular diagnostics is transforming cancer care, implementing novel technologies remains challenging. This study identifies unmet needs and technology requirements through a two‐step stakeholder involvement. Liquid biopsies for monitoring applications and predictive biomarker testing emerge as key unmet needs. Technology requirements vary by

Evaluation of Extraction Methods for the Recovery of Vertebrate DNA From Spider Webs

open access: yesEnvironmental DNA
Spider webs have recently been recognized as an excellent source of vertebrate eDNA. Here we compare four sample preparation methods and three commercially available DNA extraction kits to optimize vertebrate eDNA recovery. We assessed DNA yield, purity,

Native Plasmid-Encoded Mercury Resistance Genes Are Functional and Demonstrate Natural Transformation in Environmental Bacterial Isolates. [PDF]

open access: yes, 2019
Plasmid-mediated horizontal gene transfer (HGT) is a major driver of genetic diversity in bacteria. We experimentally validated the function of a putative mercury resistance operon present on an abundant 8-kbp native plasmid found in groundwater samples ...

Increased variability of microbial communities in restored salt marshes nearly 30 years after tidal flow restoration [PDF]

open access: yes, 2012
We analyzed microbial diversity and community composition from four salt marsh sites that were impounded for 40–50 years and subsequently restored and four unimpounded sites in southeastern Connecticut over one growing season.

Consequences of environmental DNA pooling

open access: yes, 2020
DNA-based techniques are increasingly used to assess biodiversity both above- and belowground. Most effort has focussed on bioinformatics and sample collection, whereas less is known about the consequences of mixing collected environmental DNA (eDNA), post-extraction and pre-PCR.

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

Complete mitochondrial genome for the Mobile River Basin endemic Coal Darter, Percina brevicauda (Perciformes, Percidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The Coal Darter (Percina brevicauda) is endemic to just three watersheds within the upper Mobile River basin in Alabama. Coal Darters are imperiled and are recognized as a species of conservation priority by the Alabama Department of Wildlife and ...

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

open access: yesMolecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.
