Transcriptomic Profiling Reveals 17β-Estradiol Treatment Represses Ubiquitin-Proteasomal Mediators in Skeletal Muscle of Ovariectomized Mice.

J Cachexia Sarcopenia Muscle

February 2025

Division of Physical Therapy and Rehabilitation Science, Department of Family Medicine and Community Health, University of Minnesota, Minneapolis, Minnesota, USA.

Background: With a decline of 17β-estradiol (E2) at menopause, E2 has been implicated in the accompanied loss of skeletal muscle mass and strength. We aimed at characterizing transcriptomic responses of skeletal muscle to E2 in female mice, testing the hypothesis that genes and pathways related to contraction and maintenance of mass are differentially expressed in ovariectomized mice with and without E2 treatment.

Methods: Soleus and tibialis anterior (TA) muscles from C57BL/6 ovariectomized mice treated with placebo (OVX) or E2 (OVX + E2) for 60 days, or from skeletal muscle-specific ERα knockout (skmERαKO) mice and wild-type littermates (skmERαWT), were used for genome-wide expression profiling, quantitative real-time PCR and immunoblotting.

Dep. Biologia & CESAM - Centre for Environmental and Marine Studies, Universidade de Aveiro, Campus de Santiago, 3810-193 Aveiro, Portugal; South Iceland Research Centre, University of Iceland, Lindarbraut 4, 840-IS Laugarvatn, Iceland.

Despite the vital importance of wetlands globally, these habitats have increasingly received anthropogenic materials, such as plastics, which can impact the wildlife these habitats support. Despite commonly found in the nests of Eurasian spoonbill (Platalea leucorodia), the presence of such materials has never been quantified. Here, we monitored the occurrence of anthropogenic nesting materials (ANM) in spoonbill nests in the Camargue wetland in Southern France during two breeding seasons (2021-2022).

Active matter, from motile bacteria to animals, can exhibit striking collective and coherent behavior. Despite significant advances in understanding the behavior of homogeneous systems, little is known about the self-organization and dynamics of heterogeneous active matter, such as complex and diverse bacterial communities. Under oxygen gradients, many bacterial species swim towards air-liquid interfaces in auto-organized, directional bioconvective flows, whose spatial scales exceed the cell size by orders of magnitude.

Human recombination maps are a valuable resource for association and linkage studies and crucial for many inferences of population history and natural selection. Existing maps are based solely on cross-over (CO) recombination, omitting non-cross-overs (NCOs)-the more common form of recombination-owing to the difficulty in detecting them. Using whole-genome sequence data in families, we estimate the number of NCOs transmitted from parent to offspring and derive complete, sex-specific recombination maps including both NCOs and COs.

Kinship clustering within an ecologically diverse killer whale metapopulation.

Heredity (Edinb)

January 2025

Centre for Ecological and Evolutionary Synthesis, Department of Biosciences, University of Oslo, Oslo, Norway.

Metapopulation dynamics can be shaped by foraging ecology, and thus be sensitive to shifts in prey availability. Genotyping 204 North Atlantic killer whales at 1346 loci, we investigated whether spatio-temporal population structuring is linked to prey type and distribution. Using population-based methods (reflecting evolutionary means), we report a widespread metapopulation connected across ecological groups based upon nuclear genome SNPs, yet spatial structuring based upon mitogenome haplotypes.
