1. Translational research of the quaking gene : Focusing on the conjunction between development and disease
Sammanfattning : Quaking (QKI) is an RNA binding protein involved in the post-transcriptional regulation of gene expression. Originally identified as the cause of hypomyelination in a mouse mutant, it has since been consistently implicated in a wide range of neurological diseases. LÄS MER
2. Musculoskeletal Development in Jawed Vertebrates : Gene function, cis-regulation, and 3D phenotypes in zebrafish
Sammanfattning : Vertebrate skeletons are an intricate framework of bony and cartilaginous structures that form through carefully orchestrated developmental processes, guided by interacting genetic pathways that regulate cellular differentiation, migration, and tissue morphogenesis. The specific timing and localisation of gene expression shapes the diverse array of skeletal elements, from the flexible cartilages of the embryonic stage to the hardened bones that provide structural support in adulthood, and the joints and connective tissues that articulate the musculoskeletal system.

3. Population genetic history and patterns of admixture : Examples from northeastern and southern Africa
Sammanfattning : The origin of humans lies in Africa, as has been shown by archaeology, paleontology and genetics. Here, we can find the largest genetic diversity and the deepest split among human populations. African genetic diversity has been shaped by a long and complex history. LÄS MER
4. 100 million years of shark macroevolution : A morphometric dive into tooth shape diversity
Sammanfattning : Few vertebrate clades exhibit the evolutionary longevity and versatility of sharks, which constitute nearly half of all current chondrichthyan biodiversity and represent an ecological diversity of mid-to-apex trophic-level predators in both marine and freshwater environments. The rich fossil record of shark teeth from Mesozoic and Cenozoic rocks also makes the group amenable to large-scale quantitative analyses. LÄS MER
5. Silurian vertebrates of Gotland (Sweden) and the Baltic Basin
Sammanfattning : During the Silurian, the Swedish island Gotland was positioned close to the equator and covered by a shallow sea called the Baltic Basin. The sedimentary rocks (predominantly carbonates) comprising most of the island today were initially formed in this warm sea, and the relatively complete succession of rocks often contains fossil fragments and scales from early vertebrates, including heterostracans, anaspids, thelodonts, osteostracans, acanthodians, and a stem-osteichthyan.
