Genome-wide signatures of convergent evolution in echolocating mammals [PDF]

open access: yes, 2013
Evolution is typically thought to proceed through divergence of genes, proteins, and ultimately phenotypes(1-3). However, similar traits might also evolve convergently in unrelated taxa due to similar selection pressures(4,5).

Short peptide perturbs spermatogenesis via immune microenvironment dysregulation and mitochondrial imbalance

open access: yesFEBS Open Bio, EarlyView.
In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Earthing effects on mitochondrial function: ATP production and ROS generation

open access: yesFEBS Open Bio, EarlyView.
In contrast to sham and naive controls, grounded mitochondria not only exhibit significantly enhanced energy production but also demonstrate a remarkable reduction in membrane potential and oxidative stress. This suggests a profound improvement in mitochondrial health, presenting a promising avenue for therapeutic interventions.

The complete mitochondrial genome of the critically endangered Atlantic humpback dolphin, Sousa teuszii (Kükenthal, 1892)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The Atlantic humpback dolphin remains an understudied, critically endangered cetacean species. Here, we describe the first complete mitogenome of Sousa teuszii, derived from an animal stranded on Île des Oiseaux, Sine Saloum, Senegal. The S.

Larger mammalian body size leads to lower retroviral activity [PDF]

open access: yes, 2014
Retroviruses have been infecting mammals for at least 100 million years, leaving descendants in host genomes known as endogenous retroviruses (ERVs). The abundance of ERVs is partly determined by their mode of replication, but it has also been suggested ...

Biophysical characterization and ion transport with cell‐based and proteoliposome reconstitution assays of invertebrate K+‐Cl− cotransporters

open access: yesFEBS Open Bio, EarlyView.
The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Co‐overexpression of the caloric restriction‐induced mitochondrial factors PGC‐1α and MIPEP upregulates Phospho1 expression in adipocytes

open access: yesFEBS Open Bio, EarlyView.
Caloric restriction that extends lifespan induces the expression of PGC‐1α and MIPEP in white adipose tissue. In this study, co‐overexpression of Pgc‐1α and Mipep upregulated the gene expression of PHOSPHO1. These findings provide new insights into mitochondria‐related mechanisms underlying the effects of caloric restriction in adipocytes.

Identifying presence or absence of grizzly and polar bear cubs from the movements of adult females with machine learning

open access: yesMovement Ecology
Background Information on reproductive success is crucial to understanding population dynamics but can be difficult to obtain, particularly for species that birth while denning. For grizzly (Ursus arctos) and polar bears (U.
