Don't know about you lovely lot, but it's definitely been one of those....weeks when the world would indeed be a calmer and quieter place if I had been born with the überly useful powers to instantly mince someone into an amorphous pile of steaming mush...just by smiling at them.

So, on this first day of February, I shall try to be my best self until that time arrives and I finally snap and become the human embodiment of Kali whilst mincing all asunder.

Study shows that morphogens in #Drosophila blastoderm control formation of cell densities along the #DVaxis that in turn is necessary for fine-tuning #morphogen gradient levels; #frazzled & #GUKholder are key effectors in this process #PLOSBiology https://plos.io/3YKufMO
The epithelial polarity genes frazzled and GUK-holder adjust morphogen gradients to coordinate changes in cell position with cell fate specification

Morphogenetic gradients specify distinct cell populations within tissues. Originally, morphogens were conceived as substances that act on a static field of cells, yet cells usually move during development. Thus, the way cell fates are defined in moving cells remains a significant and largely unsolved problem. Here, we investigated this issue using spatial referencing of cells and 3D spatial statistics in the Drosophila blastoderm to reveal how cell density responds to morphogenetic activity. We show that the morphogen decapentaplegic (DPP) attracts cells towards its peak levels in the dorsal midline, whereas dorsal (DL) stalls them ventrally. We identified frazzled and GUK-holder as the downstream effectors regulated by these morphogens that constrict cells and provide the mechanical force necessary to draw cells dorsally. Surprisingly, GUKH and FRA modulate the DL and DPP gradient levels and this regulation creates a very precise mechanism of coordinating cell movement and fate specification.

So far this morning I have delivered 6 Christmas presents, 35 cards, donations for the school Christmas party, donations for the local food bank, collected a 2nd hand school uniform order AND made my train on time #Winning #SchoolRun #Frazzled
