<p class=MsoNormal> </o:p>

<p class=MsoNormal><b style='mso-bidi-font-weight:normal'> Objective </b>: Disrupt silencing to activate a gene.</o:p>

<p class=MsoNormal>Remodel chromatin so that heterochromatin can be uncoiled and opened into euchromatin so they can be activated and freely available.</o:p>

<p class=MsoNormal> </o:p>

<p class=MsoNormal>We’re <i style='mso-bidi-font-style:normal'>turning on</i> the already silenced genes to produce the desired response (shift the activated genes towards silencing) by opening heterochromatin and acetylating them to become euchromatin and open.</o:p>

<p class=MsoNormal> </o:p>

<p class=MsoNormal><b style='mso-bidi-font-weight:normal'>Rationale</b> - In some cases, we will want differentiation to lead to gene expression (instead of gene silencing).</o:p>

<p class=MsoNormal> </o:p>

<p class=MsoNormal> Milestone : Create multiple fusions of DNA binding domains and activations domains.</o:p>

<p class=MsoNormal> </o:p>

<p class=MsoNormal> More specifically…  </o:p>

<p class=MsoNormal>We are creating our anti-silencing circuits using various DNA Binding Domains and activation domains. (As shown below)</o:p>

<p class=MsoNormal> The function of each is such :<o:p></o:p>

<p class=MsoNormal>1. We’re using various<span lang=ES-VE style='mso-ansi-language: ES-VE'> LexA domains to compete for the<span lang=EN-GB style='mso-ansi-language:EN-GB'> LexA binding site. This won’t necessarily open heterochromatin, but it will prevent DNA from becoming heterochromatin because it will block and HDAC from binding to the <span class=SpellE>LexA binding site and therefore inhibit the DNA from becoming silenced.<o:p></o:p>

<p class=MsoNormal>2. We’re using HATs such as Sas2 and Esa1 because they will cause an oozing model where we end up acetylating the heterochromatin and “open” it into euchromatin.<o:p></o:p>

<p class=MsoNormal>3. We’re using VP64 - as a reader to attract <span class=SpellE>HATs (writers) to they will acetylate for us and open the heterochromatin for us indirectly.<o:p></o:p>

<p class=MsoNormal>4. We’re using mCherry just as a reporter of expression level so we can run a FACs on it.<o:p></o:p>
