Use of Replicators in Gene Therapy

Mirit Aladjem, Cindy Tseng, Haiqing Fu and Lixin Wang (NCI).

U.S. Provisional Application No. 60/715,113 filed 07 Sep 2005 (HHS Reference No. E-309-2005/0-US-01).

There remains a need for a gene therapy vector capable of delivering a stably maintained, appropriately-regulated therapeutic transgene without adverse side effects. Lack of expression of a therapeutic transgene is still a major obstacle for gene therapy and the extent of transcriptional silencing of gene therapy vectors depends on their chromosomal location and on the presence of nearby heterochromatin. Most active genes replicate early during S phase, while transcriptional silencing correlates with late replication. The location of DNA replication initiation events on chromatin is affected by DNA sequences termed replicators, which interact with distal sequences to establish an epigenetic permissive state that directs the replication machinery to the replicator at a specific time during S phase. NIH researchers at the National Cancer Institute have now shown that inclusion of functional replicators in transgenes are able to prevent gene silencing, suggesting that replicator sequences have an important role in stabilizing gene expression patterns. The ideal gene delivery vector system would include functional elements that permit stable maintenance and long-term regulated transgene expression and the inclusion of replicators may be key Start Printed Page 10981in the prevention of gene silencing and replication delay.

Claims are directed to specific constructs and methods of using replicators and transgene constructs to inhibit, delay or prevent gene silencing and are available for licensing. The addition of these sequences to non-replicating or self-replicating gene delivery systems may be key in the development of effective gene delivery vectors.

TNF-alpha Converting Enzyme Inhibitory Agents and Stimulatory Agents

Stewart J. Levine et al. (NHLBI).

U.S. Provisional Application No. 60/505,394 filed 24 Sep 2003 (HHS Reference No. E-208-2003/0-US-01); PCT Application No. PCT/US2004/031608 filed 24 Sep 2004, which published as WO 2005/030798 on 07 Apr 2005 (HHS Reference No. E-208-2003/0-PCT-02).

The action of Tumor Necrosis Factor alpha (TNF-alpha) has been implicated in such diseases as arthritis, sepsis, ulcerative colitis, multiple sclerosis, Crohn's disease, septic shock, graft rejection, cachexia, insulin resistance, post-ischemic reperfusion injury, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, proteinuria, aneurismal aortic disease, degenerative cartilage loss, demyelinating diseases of the nervous system, and HIV infection. TNF-alpha converting enzyme (TACE) or ADAM 17 (A Disintegrin And Metalloprotease) is a member of a family of zinc metalloproteases, and is an important regulator of inflammation, immune regulation, and cellular proliferation as a consequence of its ability to catalyze the activation of TNF-alpha from a membrane bound to a soluble form.

The NIH announces the identification of a protein, corresponding to the amino-terminus of the TACE prodomain, that possesses a TACE inhibitory activity that is independent of a cysteine-switch mechanism. This TACE inhibitory protein could be used as a new therapeutic agent against chronic inflammatory diseases that are mediated by TNF-alpha.
