... transfer is as simple and straightfor- ward as possible. On the other hand, they need to encode sufficiently fine-grained information to steer transfer. Furthermore, target and source representations ... quasi- semantic representation for transfer and gener- ation. The translation between f-structures and terms is based on the correspondence between directed graphs represe...

... H4-K5, K8 and K12 acetylation [136–138]. In yeast, this group is made up of NuA4 and Piccolo NuA4 which both uti- lize Esa1 as the HAT, and Esa1 was found to be essen- tial for H4-K5, K8 and K12 ... Tip60 which forms a NuA4-like complex, and HBO1 which more closely resembles yeast Piccolo NuA4 [138]. In mammals, it is HBO1 and not Tip60 which is responsi- ble for the bulk of t...

... tumors and cell lines, miR-17- 5p and miR-20a are induced in a manner that depends on cyclin D1 and repress the expression of cyclin D1. Hence, miR-17-5p ⁄ 20a and cyclin D1 form a feedback loop and ... cross-linking and immunoprecipitation also provides genome-wide inter- action maps for miRNAs and mRNAs, which enables comprehensive identification of miRNA targets [60]. By int...
