CONCLUSIONS FROM RANDOM BROWSING
Signal from IsoG and U1 KD die off somewhat similarly (albeit more sharply for U1):
   chr5:17,200,626-17,286,669 Basp1
   chr1:8,006,937-8,048,469 Park7
   chr1:9,845,823-9,896,246 CLSTN1

U1 signal persists longer into the gene:
   chr1:6,648,755-6,664,826 KLHL21 -- I worry here about DNA contamination a little. Who did our DNAseI treatment, and how do we know it worked?
   chr1:6,240,600-6,263,143 RPL22
   chr1:8,066,848-8,088,781 ERRFI1

U1 KD is so weak it's hard to even tell if there is an effect
   chr1:8,917,306-8,944,077 Eno1

CONCLUSIONS FROM HIGHLY-EXPRESSED GENES

Similar effect, but U1 knockdown extends out further and drops more binarily
   chr16:89,985,665-90,007,664 Tubb3
   chr12:6,639,632-6,651,490 Gapdh
  
   chr12:104,680,460-104,744,085 Txnrd1 clear diff between U1 and isog. looks more berg like than sharp-like.
