They grow up so fast – MRes Spring 2017

April time again and the end of another block of MRes Clinical Sciences projects. This time the Hamill lab hosted three students; Kareem Hassanin, Conro Conro Sugden and Tobi Oyewole. Today the boys had their presentations/poster session.

First up; Conro told his story of developing our new minigene construct to investigate LaNt regulation and testing a few mutant versions of it to prove it works. Conor, with Lee Troughton’s help, did some excellent work; generating flo2017-04-13 15.38.50w cytometry,
RT-PCR, western blotting and fluorescence microscopy images that demonstrate that our new system is effective for studying intron retention and alternative polyadenylation and showing that the exon 9 splice site has a big role to play in determining splicing efficiency. His data has gone straight into a grant application and should form the starting point for the next stage of the LaNt project.

Next, Tobi under 20170413_120630the joint supervision of myself and Colin Willoughby and working alongside Fight For Sight student Thanos, worked on determining the optimal delivery mechanism and conditions for delivering small RNA molecules into corneal epithelial cells. This work is critical first step for the the next stage of Thanos’ PhD studies and, although Tobi was frustrated at times, makes a big difference to the lab. Optimisation is the biggest part of all experiments, without these steps we wouldn’t be able to ask the big questions.

Finally, Kareem working alongside Dr Valentina Barrera and using samples kindly provided by Prof Geor20170413_141809ge Bou Gharios, optimised our new rabbit anti-mouse LaNt antibody staining protocol and then did the first staining of embryos and various tissues in the adult. These are really short projects and filled with frustration as just at the very end, Kareem finally had conditions nailed down to get super clean, specific, staining that has opened up a whole range of new options and research questions. One thousand emails bounced back and forward yesterday as he tried to identify all the structures that were and were not stained. Although super cool, really this is just the beginning; knowing where the protein is automatically generates the question of what it is doing in that location as we predict that LaNt function is context specific, so these data too will lay the groundwork for the next grant(s) and next paper.

All in all, a really productive 3 months. Looking forward to the next block…
