Article Synopsis
  • Sarcopenia, the age-related loss of muscle mass, may stem from anabolic resistance and disrupted cellular signaling, but it's uncertain if aging alone causes these issues or if other factors play a role.!* -
  • In a study with lean young men (average age 22) and old men (average age 70), participants performed resistance exercise followed by essential amino acid intake, with muscle biopsies taken at several intervals to measure amino acid levels and muscle protein synthesis (MPS).!* -
  • Results showed both age groups had similar peak amino acid levels after exercise, but older individuals had heightened anabolic signaling in resting muscles, suggesting age may affect muscle recovery differently despite comparable exercise responses.!*

Article Synopsis
  • This study investigated the relationship between transportation noise and atrial fibrillation (AF) using data from 11 Nordic cohorts, totaling over 161,000 participants.
  • Researchers found that higher road traffic noise exposure is linked to an increased risk of developing AF, particularly in women and overweight individuals.
  • Aircraft noise also showed a potential association with AF risk, while railway noise did not appear to be related; overall, road and aircraft noise combined raised the risk significantly.

Background: Despite accumulating evidence of an association between air pollution and renal disease, studies on the association between long-term exposure to air pollution and renal function are still contradictory. This study aimed to investigate this association in a large population with relatively low exposure and with improved estimation of renal function as well as renal injury biomarkers.

Methods: We performed a cross-sectional analysis in the middle-aged general population participating in the Swedish CardioPulmonary bioImaging Study (SCAPIS; n = 30 154).

Bone morphogenetic protein 15 (BMP15) is an oocyte-specific growth factor important for successful female reproduction in mammals. While mutations in BMP15/Bmp15 cause ovulatory deficiency and/or infertility in certain mammalian species, loss of bmp15 in zebrafish, a continuous spawner and the only bmp15 knockout model in fish to date, results in complete arrest of follicle development and later female-to-male sex reversal, preventing to examine effects on ovulation/fertilization. Here, we used Atlantic salmon, a seasonal spawner, and generated bmp15 mutants to investigate ovarian development and fertility.

The emergence of new proteins is a central question in biology. Most tertiary protein folds known to date appear to have an ancient origin, but it is clear from bioinformatic analyses that new proteins continuously emerge in all organismal groups. However, there is a paucity of experimental data on new proteins regarding their structure and biophysical properties.

Article Synopsis
  • The protein p53, which regulates the cell cycle, is typically degraded by MDM2, and their interaction is influenced by specific motifs within their structures.
  • Differences in binding strength between p53 from zebrafish and from human/chicken indicate a complex evolutionary history for these interactions among ray-finned fishes.
  • Findings suggest that changes in both conserved and nonconserved regions of the p53 binding motif have evolved to increase binding affinity, demonstrating the complexities of protein interactions and the need for experimental validation in bioinformatics research.

Early puberty poses a significant challenge for male Atlantic salmon in aquaculture due to its negative impact on growth and welfare. The regulation of puberty in vertebrates involves 2 key reproductive hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) and their gonadal receptors. In male mice lacking FSH receptor, testes size is reduced, but fertility is maintained, while medaka and zebrafish with a disrupted fshr gene exhibit near normal testis size and fertility.

Background: Several studies have shown associations between cadmium (Cd) exposure and an increased risk of fractures. However, the size of the risk is still unclear and proper adjustment for smoking is a challenge. The aim of this study was to quantify the association between dietary cadmium measured in blood and fracture risk in the general Swedish population through a large population-based case-control study in never-smokers.

The virus life cycle depends on host-virus protein-protein interactions, which often involve a disordered protein region binding to a folded protein domain. Here, we used proteomic peptide phage display (ProP-PD) to identify peptides from the intrinsically disordered regions of the human proteome that bind to folded protein domains encoded by the SARS-CoV-2 genome. Eleven folded domains of SARS-CoV-2 proteins were found to bind 281 peptides from human proteins, and affinities of 31 interactions involving eight SARS-CoV-2 protein domains were determined (K ∼ 7-300 μM).

Interactions between two proteins are often mediated by a disordered region in one protein binding to a groove in a folded interaction domain in the other one. While the main determinants of a certain interaction are typically found within a well-defined binding interface involving the groove, recent studies show that nonspecific contacts by flanking regions may increase the affinity. One example is the coupled binding and folding underlying the interaction between the two transcriptional coactivators NCOA3 (ACTR) and CBP, where the flanking regions of an intrinsically disordered region in human NCOA3 increases the affinity for CBP.

We discuss the aetiology of recurrent abdominal pain of non-organic origin, according to the Rome Criteria for Functional Gastrointestinal Disorders and a psychogenic hypothesis. Stress activates the brain-gut axis, which is important for local gut symptoms, such as abdominal pain, but it also causes pain in other areas, including the head, back and chest. Our research has indicated that the startle reflex plays a dominant role in this stress-induced pain pattern, which is manifested in the whole body.

The interaction between the transcription factor p53 and the ubiquitin ligase MDM2 results in the degradation of p53 and is well-studied in cancer biology and drug development. Available sequence data suggest that both p53 and MDM2-family proteins are present across the animal kingdom. However, the interacting regions are missing in some animal groups, and it is not clear whether MDM2 interacts with, and regulates p53 in all species.
