Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The costs of breed reconstruction from cryopreserved material in mammalian livestock species

open access: yesGenetics Selection Evolution, 2007
The aim of this work was to compare costs, in the horse, cattle, sheep, swine, and rabbit species, for the creation of gene banks for reconstruction of an extinct breed, using different strategies: embryos-only, embryos in combination with semen, and ...

The WTP for property rights for the Giant Panda: can a charismatic species be an instrument for conservation of natural habitat? [PDF]

open access: yes, 2002
The paper presents the results from a stated preference study to address issues concerning the potential for using flag-ship species, such as the Giant Panda, to purchase the property rights for the conservation of natural habitat. The study finds, first,

Next‐generation metrics for monitoring genetic erosion within populations of conservation concern

open access: yesEvolutionary Applications, 2017
Genetic erosion is a major threat to biodiversity because it can reduce fitness and ultimately contribute to the extinction of populations. Here, we explore the use of quantitative metrics to detect and monitor genetic erosion.

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

open access: yesMolecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

Determinants of cereal diversity in communities and on household farms of the Northern Ethiopian Highlands: [PDF]

open access: yes
"On farm conservation of crop diversity poses obvious policy challenges in terms of the design of appropriate incentive mechanisms and possible trade-offs between conservation and productivity.

Extinctions, genetic erosion and conservation options for the black rhinoceros (Diceros bicornis)

open access: yesScientific Reports, 2017
The black rhinoceros is again on the verge of extinction due to unsustainable poaching in its native range. Despite a wide historic distribution, the black rhinoceros was traditionally thought of as depauperate in genetic variation, and with very little ...

YAP1::TFE3 mediates endothelial‐to‐mesenchymal plasticity in epithelioid hemangioendothelioma

open access: yesMolecular Oncology, EarlyView.
The YAP1::TFE3 fusion protein drives endothelial‐to‐mesenchymal transition (EndMT) plasticity, resulting in the loss of endothelial characteristics and gain of mesenchymal‐like properties, including resistance to anoikis, increased migratory capacity, and loss of contact growth inhibition in endothelial cells.

On farm conservation of rice biodiversity in Nepal: a simultaneous estimation approach [PDF]

open access: yes
"This paper presents an empirical case study about farmer management of rice genetic resources in two communities of Nepal, drawing on interdisciplinary, participatory research that involved farmers, rice geneticists, and social scientists.

The concept of "Networked collection" or "Virtual collection"?: revisiting the classical delineation between "in situ" and "ex situ" conservation and its consequences on database management [PDF]

open access: yes, 2009
A networked collection, also called a virtual collection, is located at more than one geographical/institutional site, spans the genetic diversity of a given species (genepool) and gathers stakeholders having a mutual interest in rationally conserving ...
