SF 424 AI110964-06 (received date 11/05/2018) Both SF 424s seem to be describing "gain of function" experiments. On page 192 of SF 424 AI110964-06 (received date 11/05/2018) under P3CO Research, it indicates they are conducting gain of function of SARSr-CoV. Were they also conducting Seemless Cloining and Assembly? From a review of their experimental details, it looks as if they were generating recombinant DNA of the viruses using WIV1 as the backbone but I could not determine if they were using Seemless Cloning techniques. I could not determine exactly where they were conducting these gain of function experiments. I know UNC-Chapel Hill has done these but within the document, I could not determine where this was occurring. Do you know where this was occurring? It then appears that the recombinant DNA of the virus was then injected into humanized mice. However, again I couldn't determine where this occurred or was to occur. On page 187 of the same SF 424 under "Vertebrate Animals" it indicates that work with vertebrate animals will be conducted at Wuhan University at the School of Medicine and UNC - CH. Then under "Laboratory Mice" it states that lab mice will be sourced commercially by Wuhan Center for Animal Experiment at Wuhan University and that humanized mice will be bread at University of Wuhan and UNC - CH. Furthermore, the mice will be inoculated with the virus. Under "UNC Facilities where selected agents to be used" it continues with all mouse studies at UNC-CH will be performed...." However, on page 200 of the same SF 424 there is a letter from UNC - CH stating "The work to be performed by UNC-CH does not include animal and/or human research subjects." I know that was a lot of information but where exactly was the experimentation of injecting the humanized mice with the recombinant DNA occurring? SF 424 AI110964-01 (received date 06/05/2013) In this SF 424 Aim 3 seems indicative of gain of function experimentation (C3a and C3b) although it does not use that exact term. On page 119 of AI110964-01 under "C3d) Humanized mouse in vivo infection experiments" it states that humanized mouse in vivo experiments in humanized mice was occurring at the Wuhan Institute of Virology. I did not see the location where these gain of function experiments were being done but if the injections were occurring at WIV then was the recombinant DNA also generated at WIV? Was Seemless Cloning also being done? RPPR (AI110964-05) Finally, in the RPPR (6/1/2017-5/31/2018) on page 28 under "In Vivo Infection of Human ACE2 Expressing Mice with SARSr-Cov S Protein variants", it appears to be showing the results from their gain of function experiments as described in the SF 424. This is more of less the same as the question above, but do you know where this occurred?
