Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

open access: yesMolecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

DNA barcoding as a complementary tool for conservation and valorisation of forest resources

open access: yesZooKeys, 2013
Since the pre-historic era, humans have been using forests as a food, drugs and handcraft reservoir. Today, the use of botanical raw material to produce pharmaceuticals, herbal remedies, teas, spirits, cosmetics, sweets, dietary supplements, special ...

Evaluating the Utility of Single-Locus DNA Barcoding for the Identification of Ribbon Worms (Phylum Nemertea). [PDF]

open access: yesPLoS ONE, 2016
Whereas many nemerteans (ribbon worms; phylum Nemertea) can be identified from external characters if observed alive, many are still problematic. When it comes to preserved specimens (as in e.g.

Using molecular tools to differentiate closely related blackfly species of the genus Simulium [PDF]

open access: yes, 2009
Biodiversity data are the foundation for conservation and managemet and taxonomy provides the reference system, skills and tools used to identify organisms.

A record of the Porbeagle, Lamna nasus, in coastal waters of Buenos Aires (Argentina) confirmed by DNA barcoding [PDF]

open access: yes, 2015
A record of a juvenile Porbeagle, Lamna nasus, in the coastal waters of Argentina is confirmed by DNA barcoding, since the specimen lacked some external diagnostic features.

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

open access: yesMolecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Evaluation of DNA barcoding reference databases for marine species in the western and central Pacific Ocean [PDF]

open access: yesPeerJ
DNA barcoding is a widely used tool for species identification, with its reliability heavily dependent on reference databases. While the quality of these databases has long been debated, a critical knowledge gap remains in their comprehensive evaluation ...

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

open access: yesFEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

DNA barcoding deep-water zooplankton from the Gulf of Alaska, North Pacific Ocean

open access: yesFrontiers in Marine Science
DNA barcoding is a method of identifying individual organisms using short DNA fragments matched to a database of reference sequences. For metazoan plankton, a high proportion of species that reside in the deep ocean still lack reliable reference ...
