| 摘要 |
The present invention relates to a method of monitoring epigenetic changes comprising monitoring changes in conditional long range chromosomal interactions at at least one chromosomal locus where the spectrum of long range interaction is associated with a specific physiological condition, the method comprising the steps of:—(i) in vitro crosslinking of said long range chromosomal interactions present at the at least one chromosomal locus; (ii) isolating the cross linked DNA from said chromosomal locus; (iii) subjecting said cross linked DNA to restriction digestion with an enzyme that cuts at least once within the at least one chromosomal locus; (iv) ligating said cross linked cleaved DNA ends to form DNA loops; (v) identifying the presence of said DNA loops; wherein the presence of DNA loops indicates the presence of a specific long range chromosomal interaction. |
