mitotic recombination loss of heterozygosity

All ASOs contained phosphorothioate linkages in the backbone and 2-O-methoxyethyl substitutions of the sugar moiety; these ASOs have no capacity to promote RNase Hmediated removal of RNAs but are useful for modulating splicing (30). [PubMed: 11529856] [PubMed: 11186940] [Full Text], Eswarakumar, V. P., Schlessinger, J. [PubMed: 16766665, images, related citations] For example, E11-31 is an ASO that binds to exon 11, starting at nt 31 of exon 11. However, when lamin A protein levels in liver extracts from the same mice were examined, lamin A levels were reduced by >40% (Figure 6B; P < 0.02).

Wild-type MEFs were transfected with ASOs E11-26, E11-31, E11-36, and I10-11 (I10-11 is located in lamin Cs 3 UTR). The results are shown for 2 wild-type mice (+/+), two LmnaG609G/G609G (609/609) mice treated with the control ASO (Con ASO1 and Con ASO2), and an LmnaG609G/G609G mouse treated with ASO E11-31 (E11-31 ASO1).

In cultured cells, progerin leads to an increased frequency of misshapen cell nuclei in a dose-dependent fashion (20), and the level of progerin expression in vivo dictates the severity of disease phenotypes, both in humans (21) and in mouse models (2225). Of note, treatment of human HGPS fibroblasts with a lamin CASO reduced progerin transcript and protein levels by >70%. Goriely, A., Hansen, R. M. S., Taylor, I.

Thanatophoric dysplasia type 2 with encephalocele during the second trimester. Srsf2 mRNA levels were reduced by >95% in the adeno-Cretreated cells. In all 16 individuals with type II thanatophoric dysplasia (TD2; 187601), they found a sporadic heterozygous mutation causing a lys650-to-glu change in the FGFR3 tyrosine kinase domain (134934.0004). A new skeletal dysplasia with severe tibial bowing, profound developmental delay and acanthosis nigricans is caused by a Lys 650 Met mutation in fibroblast growth factor receptor 3 (FGFR3).

Even though ASO E11-31 binds to sequences approximately 70 nt upstream of the HGPS mutation in codon 608 (c.1824C>T), it is possible that the lamin CASOs might increase utilization of the HGPS exon 11 splice donor site and result in larger amounts of progerin transcripts.

Keegan et al. Bellus et al. PARP2 is most closely related to PARP1 with 69% similarity in its catalytic domain, and was identified on the basis of the persistence of PARP activity in PARP1-deficient cells.1,3, Evidence for an important role of PARP in DNA repair comes from the finding that DNA damaging agents and radiation-induced DNA damage causes increased PARP activity.4 The accumulation of DNA lesions has also been found to result in a significant increase in PARP levels in cells.5 PARP is involved in base excision repair (BER) in response to single-stranded DNA breaks (SSBs) and is a component of the BER complex, which consists of DNA ligase III, DNA polymerase beta, and the XRCC1 protein.6 In cell-free systems, it has been shown that the unmodified PARP enzyme binds tightly to DNA strand breaks and following autopoly ADP-ribosylation, is released and allows for repair enzyme access to the damaged DNA.2,7 Both PARP1 and PARP2 also interact, and share common partners in the SSB repair and BER pathways, although PARP2 also has unique partners, such as the telomeric protein TRF-2.1,8,9.
