|''Every year over 1.2 million people suffer myocardial infarction (MI). The resulting heart damage requires new approaches for effective repair. Stem cell therapies provide hope. However none of the stem cell therapies currently in clinical trials addresses the need for efficient stem cell targeting to cardiac tissue or the need to replace efficiently dead tissue with new cardiomyocytes. To address these problems, we have built several genetic circuits that work sequentially to repair the heart. First, we have built an inducible differentiation circuit that closely resembles the endogenous differentiation pathway, to program cells to become cardiomyocytes. Second, we have built circuits that use the extracellular domains of chimeric proteins to target cells to damaged cardiac tissue. Upon binding, novel receptor-coupled intein-mediated signaling domains activate effector genes that then aid in integration, inhibition of cell death, and the alteration of the tissue microenvironment.''

Quantify aMHC cut with BspDI and NheI, pBlue cut with with BspDi and SalI on 0.8% gel, respectively, is 7ng and 13ng/ul. both are gel isolations (1ul each, 10ul lambda)
+
-
SLIC: 2ul BSA, 2ul NEBuffer 2, 1ul of 0.05U/ul T4 Polymerase (first diluted 1ul enzyme at 3U/ul in 5ul nebuf2, took one of that and diluted in 9ul water) all added to the following:
+
-
 
+
-
10ul pBlue (KpnI and SacI), 5ul water (100ng, 3000bp)
+
-
10ul tet-nkx(blue), 5ul water (100ng, 1300bp)

-
10ul gata-2a-red(blue), 5 water (100ng, 2150)
+
-
Incubate SLIC pieces in 23 C robocycler for thirty minutes. Kill reaction with 1/10vol dCTP (2ul each), ice.
+
-
 
+
-
Ligation: Each gets 1ul 10x ligation buffer, 1ul recA at 20ng/ul (diluted first 1ul recA at 2000ng/ul into 10ul 10x buffer and 89ul water)
+
-

1.4 tet-nkx-2a, 0.9 gata-2a-red, 2/3ul pblue, 15.03 water
+
-
Incubate ligation for 30minutes in 37 degree incubator, then ice
+
-
 
+
-
Transform the pieces into DH5A cells
+
-
 
+
-
add 1ul of each ligation with 50ul thawed cells (careful of heat). mix, put into thawed cuvette, shake to bottom, wipe of moisture, hope for the best and shock at 2.5kV (pulse greater than 4.9...), no spark yay!
+
-
transfer to new 1.5ml tube, add 200ul LB, shake for one hour
+
-
Plate onto LB+Amp plates. Use 100ul. (plates prewarmed to rid of moisture)
+
-
 
+
-
Now, non SLIC: Minis of pLenti
+
-

First, a warning. Apparently these guys were supposed to be transformed into HP101 cells, not DH5A, since DH5A will undergo recombination. I will pull tons of colonies and hope for the best. Else we have to transform again into HP101. Apparently, though, they like to spit out plasmids, so we'll have to be quick with those, one day.
+
-
pellet 1ml LB solution, resuspend in 250ul fridged RNase added P1 buffer, add 250ul P2, invert to mix, add 350ul N3, invert to mix. Ice ten minutes. Centrifuge 10 minutes, decant supernatant to spin column. Centrifuge 1 minute. Dispose wash through, add 75ul wash buffer PE, cent, dispose, cent, new catch tube. Incubate in 50ul elution buffer EB for couple minutes. Centrifuge for one minute and collect the DNA.

Ligations of aMHC and cmv-rtTA with poly A tails into pBluescript
+
-
 
+
-
pblue: 3000bp, 13ng/ul
+
-
aMHC, 2000bp, 07ng/ul, want 3.9:1, so must go 9:2.5 (don't have 9.75 alas)
+
-
cmv_, 1413bp, 80ng/ul, want .23:1, so must go 0.58:2.5 (Hmm, I made a mistake here. I used/found the new version which has a 30ng/ul concentration. Sadly, this is now close to 1:1 ratio instead of 3:1)
+
-
sv40: 161bp, 20ng/ul, want 0.16:1, so must go 0.26:2.5
+
-
 
+
-
The following get: 2ul T4 ligase buffer, 1ul T4 ligase, 2.5ul pBlue +
+
-
9ul aMHC, 0.26SV40, 4.5 water
+
-
0.6cmv-rtta, 0.26SV40, 13.64 water
+
-
NEGATIVE CONTROL has only 14.5 water added
+
-
 
+
-
Overnight ligation at 13 C (roboscyer set temp) in at 8:22PM
+
-
TO DO:
+
-
 
+
-
Restriction digest with MluI to check for the insert in pLenti. Restriction digest of pLenti backbone because recombination is our evil.
+
-
Transform aMHC and cmv-rtta constructs after cleaning via ammonium acetate precipitation.
+
-
Make minis from the transformed SLIC method stuff.
+
-
Probably should redo cmv ligation reaction, can trash if the first guy worked.
+
-
Attach gel images.

-
 
+
-
problem, i didn't get a new catch tube, so ran the elution through the column a second time (in the elution buffer still)
+
-
ran a gel including Nkx gel iso, quantified at 2ng/ul... ouch!
+
-
 
+
-
diluted dCTP from 100mM to 10mL, 2ul of the 100mM and 18ul of water.

-
 
+
-
Set up SLIC (the following ALL include 2ul BSA, 2ul Nebuffer2, 1ul of above enzyme mixture (for 0.05U of enzyme)

gel isolate, now, those pieces that we thought were gel isolated: 5ul 2log-20 of all following in two lanes each
+
-
 
+
-
2a-red(gata), 2a-red(nkx), tet-nkx-2a, tet-gata, tet-nkx

-
 
+
-
gel isolate the pBluescript digest and the controls to check enzyme cutting.
+
-
 
+
-
2 log - uncut pblue - bspd1 cut - sali cut - cut with both - large cut with both to iso
+
-
strange, the control uncut looked the same as these linear cuts... ???
+
-
ammonium acetate precipitate aMHC: first ice after heat inactive, then add 1ul glycogen, 7 ammonium acetate, 70 100% ethanol, ice ten minutes, spin 15 minutes, wash with 98ul 70% ethanol, centrifuge 5 minutes, air dry, resuspend in 10ul water. in blank box next to iso of pBlue

-
(I screwed up royally here. First, I pipetted, which created lots of bubbles. Second, I pipetted out the solution on all plates before swooshing it around to cover the entire plate. More than half the plates were lost because the gel hardened before theentire plate was covered. When I realized what had happened. I took the rest of the mixture and just started pouring it, swooshing it, pouring, swooshing, etc. Got a bunch of plates that way. However, the last few, a few chunks fell into the plates. All in all I wasted a lot... Sorry.

Noted that BspDI may not have cut the pBluescript. We didn't have an uncut control on the gel to compare. Wanted to see if we could get what we thought was the cut with BspDi and cut it again with something else to check if BspDI cut or not. Chose ScaI because it would give two distinct bands if BspDI worked, but only the linearized form if not. However, the old reaction had loading dye in it. Tried ammonium acetate precipitation.

try phusion and la taq polymerases

redilute oligos, double check...

gel isolate tet and nkx, then try the fusion!

-
can try more cycles for the amplification of tet-nkx from the gel iso because the small amount of dna that might be present

can raise temperatures to attempt to avoid any hairpins in the fusion region

Chose 450 band because aMHC is itself about 380bp, the oligos add 20bp flanking, and the fusion with neor adds 20bp from restriction sites and 20bp from neor fusion overhang. the 400 band is also in a tube should we find that's somehow what we want instead. can then fuse neor with amhc using this stuff.

The gata4 looks good. i see what look like the appropriate bands.

eco should have 3939, 1344.

psti should have 5283

pvuii should have 2619, 1711, 593, 360

noti should have 4296, 987

I think Jen meant I should use puc18, not puc19... i don't have the puc19 map.
+
-
I looked at my copy of zeo, and it doesn't look like noti even cuts...
+
-
in any case, these were the positive controls, and it looks like the enzymes worked anyway, from topo, and because the controls show that the enzymes change the banding...

Check on gel 1%, 2log ladder 5ul, gata 5ul, gata (tet) 5ul (the version of gata that binds directly to the tet promoter, not to 2a upstream), dsred 5ul, aMHC 5ul 115V
+
-
 
+
-
Saw that gata failed, dsred failed, aMHC had banding indicating likely that the primers were allowing multiple targets to be hit. Indicates future aMHC PCRs should target temperatures closer to the melt temp to avoid secondary products. Main product is main band, though.

gfp is bright, correct. 2a-gfp got nada. nkx and tet-nkx are weird semicircles (replace running buffer!?). the fusion ran even faster than the non-fusion, but it is crazy bent.

Both products look good! Finally! We have streaking though, indicating some contaminant of SDS and perhaps other. We can Probably use this product for our fusion constructs, but if that doesn't work, we probably need to run aMHC on a gel and isolate to clean it.

checked at 20, 30, 45 minutes. Have only original reactants, no product. Can check my page on gel computer for image. BMP4 is still overloaded with 3ul!!! very concentrated stuff. the small 3ul reactions of fusion didn't show. the 13.5ul reactions showed small bands (likely tcf) and basically nil at the higher ends, though a very faded band appeared, probably original bmp4 reactant, just shy of the lambda ladder (so under 1300bp), pretty even with control, though overloaded. A very high band also appeared, very very faded as well.
+
-
Realized that we never got the melt temperature of the fusion, which is really 51 degrees! Had Jen email us the rest of the constructs in case any others are like this. A20 the other day must have been a miracle, heh. Decided to redo the reaction.

(cycle as above because the overlap is only Tm=56 or Ta=51. Want to get some product with the anneal first, then can just use the 55 anneal temp for the entire thing for the flanking primers, as the overlap is now in the construct and we are just amplifying the large pieces)

looked good, but that bmp4 25 cycle dna is very concentrated! 5ul was overloaded. can't be absolutely sure that the product isn't just bmp4 (though highly unlikely as the only oligos were the flanking oligos... so i am 95% sure the product is good)

On this gel, it appears like BamHI may be cutting. Note the band even with the cut control. However, I overloaded the uncut control, so those bands can't be defined for sure.
+
-
In any case, we can see that the enzymes still work. The gels clearly show ClaI and BamHI cutting the controls. The problem is with pNEB193 version 2, our modified pNEB193 plasmid.

Ran a gel for Simina's restriction digest the day before, consisting of uncut pNEB193 as a control and Clai and BamHI as the experimentals. ClaI and BamHI did not cut.

Used 0.8% gel, ladder Lambda Bst. Used the 50ng tubes for uncut control.

Every year over 1.2 million people suffer myocardial infarction (MI). The resulting heart damage requires new approaches for effective repair. Stem cell therapies provide hope. However none of the stem cell therapies currently in clinical trials addresses the need for efficient stem cell targeting to cardiac tissue or the need to replace efficiently dead tissue with new cardiomyocytes. To address these problems, we have built several genetic circuits that work sequentially to repair the heart. First, we have built an inducible differentiation circuit that closely resembles the endogenous differentiation pathway, to program cells to become cardiomyocytes. Second, we have built circuits that use the extracellular domains of chimeric proteins to target cells to damaged cardiac tissue. Upon binding, novel receptor-coupled intein-mediated signaling domains activate effector genes that then aid in integration, inhibition of cell death, and the alteration of the tissue microenvironment.
