1. 1. Vitamin A regulated neuronal regeneration and homeostasis

   Författare :Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

   Sammanfattning : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. LÄS MER

3. 2. Exploring Biological Systems using Spatial Transcriptomic Technologies

   Författare :Kim Thrane; Joakim Lundeberg; Patrik Ståhl; Ulf Gyllensten; KTH; []
   Nyckelord :Spatial Transcriptomics; single-cell RNA-seq; scRNA-seq; spatial VDJ; Spatial Isoform Transcriptomics; Biotechnology; Bioteknologi;

   Sammanfattning : The transcriptome and the cells’ spatial organization are important determinants for the functions of biological systems, such as a tumor, brain, or skin tissue. Single-cell RNA sequencing (scRNA-seq) has emerged as a powerful tool for profiling the transcriptome of individual cells. LÄS MER

4. 3. Bax and oxidized phospholipids - a deadly complex : Apoptotic protein-lipid assemblies studied by MAS NMR spectroscopy

   Författare :Artur Dingeldein; Gerhard Gröbner; Mikael Elofsson; Tobias Sparrman; Daniel Topgaard; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; mitochondrial membranes; apoptosis; membrane dynamics and organization; Bcl-2 family proteins; Bax protein; biokemi; Biochemistry;

   Sammanfattning : Mitochondria are renowned for their vital role as cellular powerhouses because they provide ATP via cellular respiration. Additionally, these organelles also play an important role in other physiological processes, such as apoptosis. LÄS MER

5. 4. Mapping Transcriptomes in Tissues

   Författare :Ludvig Larsson; Joakim Lundeberg; Stefania Giacomello; Naveed Ishaque; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spatially resolved transcriptomics; spatial transcriptomics; transcriptomics; data analysis; rumsligt upplöst transkriptomik; rumslig transkriptomik; transkriptomik; dataanalys; Biotechnology; Bioteknologi;

   Sammanfattning : Over the past few decades, the advent of pioneering biotechnological methods has allowed scientists to analyze the molecular components of multicellular organisms with remarkable precision. The field of transcriptomics has witnessed a rapid development of technologies for gene expression profiling of biological samples. LÄS MER

7. 5. Aquatic organisms on the pill - effects on different organizational levels

   Författare :Per Hallgren; Enhet akvatisk ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EDC; EE2; 17α-ethinylestradiol; fish; zooplankton; gastropods; population growth rates; direct and indirect effects; somatic growth; invertebrates;

   Sammanfattning : Communities are composed of organisms that interact with each other and with the non-biological environment. There are also anthropogenic pollutants in the environment that also interact with the organisms. LÄS MER
