Practical Application of DNA Fingerprinting To Trace Beef
Journal of Food Protection, 2004 DNA fingerprinting allows the verification of conventional methods used to implement beef traceability. At any point along the supply chain, the identity of an animal or piece of meat can be checked by comparison of its DNA profile with an initial sample. Practical application of DNA fingerprinting to trace beef requires a choice of DNA markers as well

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

Trace DNA and street robbery: A criminalistic approach to DNA evidence
Forensic Science International: Genetics Supplement Series, 2009 Abstract It is now routine to detect trace DNA from handled objects, and with such low quantities of DNA the principles of criminalistics are now more relevant to biological evidence. This study aimed to provide data into the abundance, transfer and persistence of trace DNA, in a particular crime scenario—street robbery.

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Extraction of Trace Amount of Severely Degraded DNA
Zeitschrift für Naturforschung C, 2009 DNA extraction from food is always problematic especially from highly processed samples which contain only trace amounts of severely degraded DNA fragments. In this work, to extract trace amounts of small DNA fragments of the traditional Chinese medicine (TCM) colla corii asini derived from highly processed Equus asinus skin, three strategies were ...

The spatial organization of trace silver atoms on a DNA template
RSC Advances, 2021 This review summarized the direct link between the silver atom organization on the DNA secondary structure and the performance of AgNCs, providing an all-round support for understanding the origin of DNA/AgNCs.

Levels of autotrophy and heterotrophy in mesophotic corals near the end photic zone
Frontiers in Marine Science, 2023 Mesophotic corals live at ~30-150 m depth and can sustain metabolic processes under light-limited conditions by enhancing autotrophy through specialized photoadaptations or increasing heterotrophic nutrient acquisition.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
