A paper published in PNAS late last year claims proof of paternal inheritance of mitochondria. As every student who took Genetics at Temple will tell you, that would be quite a paradigm-shifting discovery. But perhaps there is a difference between evidence for mtDNA and evidence for mitochondria themselves? Very glad to have been offered an opportunity to contribute to this discussion.
Noah Goff has graduated with a Bachelor of Science degree in Biochemistry. Noah has worked on two very different projects in the lab: epitope tagging of Tbx5a and assessment of CRISPR/Cas9-induced homology directed repair. As if that was not enough, Noah is now helping out on the Tbx20 project before he moves to Michigan State to start in their PhD program.
Noah received the Debra and Stanley Lefkowitz Undergraduate Research Award for his accomplishments. Well deserved and congrats!
As far as I go, this paper is one more proof of how similar fish and mice are. Tip of the hat goes to Anuj Mehta, Temple undergrad (now Medical Student at Penn State) who worked on this project shuttling between the Main Campus and the Medical School, and to CST Undergraduate Research Program for supporting him.
Our paper describing engineering of conditional mutants using CRISPR/Cas9 has been published in PLOS Genetics. The work was done in collaboration with Didier Stainier's lab at the Max Planck Institute for Heart and Lung Research. Lenny Burg (tuc33231(at)temple.edu) and I (darius(at)temple.edu) would be happy to answer any questions to help you make it work in your lab. Let's flox!
P.S. A question for linguists: would it be OK to call a Cre-reverted gene trap mutant "Crevertant"?
Diana did an excellent job getting the project off the ground. Then Viktorija took over and powered through learning to perform ventricular resection, trying various ways to re-mutate tbx5a, and a number of other experiments which did not make the final cut. Retrospectively we spent too much time trying to perfect the story and should have published it a couple of years ago. Nonetheless, here it is!

Two of our genome editors, Helen Rueckert and Ralph (Casey) St. Luce, are about to hang up their DNA pens for a while. Ralph joined our lab as a sophomore back in spring of 2016 and has contributed to several projects, but his lasting legacy will be in epitope tagging of tbx20. Helen joined our lab for both semesters of her senior year after summer research in Ireland and has worked on mutagenesis of the aldh1a2 gene. Before the Temple Biology Poster session where the photos below were taken, they did a nice job cleaning up on the awards front as well: Helen received the Dr. Nina W. Hillman Memorial Award and Ralph received the AMP Award for Research. Ralph is will pursue his MD degree at the Perelman School of Medicine at the University of Pennsylvania, while Helen will take a gap year before – you guessed it – applying to Medical School as well. Both are going to make terrific doctors one day!
