Lab updates

October 2022

• Another new pre-print is out! The lab's first attempt to study the contribution of TEs to gene regulatory evolution after whole genome duplication. The very talented master student Hanna Sahlström made use of the optimized protocol for transfection of primary hepatocytes in Atlantic salmon (see link in the post below) performed a series of reporter assays on candidate TE-cis regulatory elements. (link to the pre-print here)

• New pre-print out. Optimized protocols for transfection of DNA-vectors and CRISPR RNPs into  Atlantic salmon liver primary cells. Thanks to Ragnhild Wilberg, Alex Datsomor, and Tom Harvey for leading this work. 

August 2022

• Happy to have contributed to this new paper with a nice overview of the genes and pathways involved in fatty acid metabolism in Atlantic salmon. 

June 2022

• We have made some contributions to a new paper on characterization of 121 full length alleles of the enigmatic Vitellogenin protein in bees. Paper was led by Vilde Leipart and Gro Amdam.

• Final published verion of the first metbolic model of Atlantic salmon is out in PLOS Computational Biology. Great work by Jon Olav Vik and his team! 

• New preprint out led by Matilde M. Holen reveals interactions between chitin in the feed, microbial communities and endogenous chitin metabolism in Atlantic salmon. 

May 2022

• A new pre-print out on evolution of chitin metabolism associated genes in fish (mostly salmon). Great work by Matilde Mengkrog Holen!

April 2022

• Ohh...I got promotion to full professor :-)

• Great to finally have a in-person project meeting for the Improvafish team! Lots of interesting results about the feed-microbiome interaction in the salmon gut

March 2022

• Helle Tessland Baalsrud joined the lab as a postdoc on the EBP-Nor project. Welcome! 

January 2022

• We have started our efforts to help sequence all of Norways eukaryotic species together with all the partners in the EBP-Nor project

November 2021

• The former master student in our group Johanna Wagnerberger won the NMBU-award for the best master thesis 2020. Read the news story here, and if you  are interested in her research here is a link to her thesis. 

• Our paper on rediploidization following WGD across 100 million years is out in MBE. Study was led by Manu Gundappa and Dan Macqueen at Roslin Institute. Read the paper here.

August 2021

• Exciting to get this first paper on the curious genomes of sucker fish published. Much more to come on these duplicated genomes in the year(s) to come. Study led by Trevor Krabbenhoft group at University of Buffalo. Read the paper here.

• New preprint out on metabolic modelling of Atlantic salmon. Project is led by Jon Olav Vik at NMBU. Read the paper here.

June 2021

• Excited to be part of a huge 3M EUR grant funded by NRC to help sequence and assemble all eukaryote genomes (in the world!). Project is led by Kjetill Jakobsen at UiO. 

• Yeah! Our two fantastic master students Dom and Hanna defended their thesis projects with style. Congratulations to you both! 

• Happy to share our new pre-print about 100 million years of rediploidization dynamics following WGD in a salmonid ancestor. Study led by Manu Gundappa at the Roslin Institute. Read the paper here.

May 2021

• A new paper out in Frontiers in Immunology led by Alex West at the UiT ASTI centre. Single nuclei transcriptome view of the smoltifying gill in Atlantic salmon. Read the paper here.

April 2021

• Im proud of our new paper in Genome Biology. In collaboration with Rori Rholfs and Torgeir Hvidsten we use a comparative phylogenetic model to ask: how does selection shape genome regulatory evolution following whole genome duplication? Great computatinoal biology work by Gareth and Lars! Read the paper here.

March 2021

• Congratulations and thanks Yang Jin, for including me on this new paper using lipidomics to understand physiological remoddeling during life stage transition in Salmon. Read it here.

• Happy to see our new paper in G3 on 'print'. In this paper lead by Dave Hazlerigg at UiT we show how photoperiodic history affects how young salmon respond to changes in water salinity. Read it here.

• We wrote a pop-sci outreach piece on salmon and smoltification in Aftenposten Viten (in Norwegian). Read it here.

January 2021

• Our tallented PhD student Marius has gotten his first paper accepted (based on his master project). A very nice start on the new collaboration with Phil Pope and Torgeir Hvidsten on host-microbiome interactions. 

• What a great start to the new year! Johanna defended her master thesis on CRISPR based knock out characterization of abcg2 gene involved in salmon flesh coloration. Read her work here if you are interested.

December 2020

• Ragnhild Wilberg defended her master thesis today (10th December) ! She did a fantastic job. Congrats! If you are interested in transfection of primary liver cells in Atlantic salmon click here.

November 2020

• Finally out! An interesting collaboration between animal breeders, microbiologist and a genome guy (me). We found no/little/weak effects of salmon genetics on gut microbiota composition but we did find significant associations between salmon metabolism phenotypes and the gut microbiome. Now out in Microbiome!

• A fun collaboration between quantitative geneticists and omics people (i.e. us) reveal genetic architecture of salmon metabolism! Published in GSE.

October 2020

• Happy to have been part of this exciting new paper in PLOS Genetics, led by Shona Wood and Alex West at UiT. What happends to the circadian clock genes after a genome duplication?
