One of the objectives in the development of effective cancer therapy is induction of tumor-selective cell death. Toward this end, we have identified a small peptide that, when introduced into cells via a TAT cell-delivery system, shows a remarkably potent cytoxicity in a variety of cancer cell lines and inhibits tumor growth in vivo, whereas sparing normal cells and tissues. This fusion peptide was named killer FLIP as its sequence was derived from the C-terminal domain of c-FLIP, an anti-apoptotic protein. Using structure activity analysis, we determined the minimal bioactive core of killerFLIP, namely killerFLIP-E. Structural analysis of cells using …
Bovine Herpes Virus 1 (Bhv-1) And Herpes Simplex Virus Type 1 (Hsv-1) Promote Survival Of Latently Infected Sensory Neurons, In Part By Inhibiting Apoptosis, Clinton Jones
School of Veterinary and Biomedical Sciences: Faculty Publications
α-Herpesvirinae subfamily members, including herpes simplex virus type 1 (HSV-1) and bovine herpes virus 1 (BHV-1), initiate infection in mucosal surfaces. BHV-1 and HSV-1 enter sensory neurons by cell-cell spread where a burst of viral gene expression occurs. When compared to non-neuronal cells, viral gene expression is quickly extinguished in sensory neurons resulting in neuronal survival and latency. The HSV-1 latency associated transcript (LAT), which is abundantly expressed in latently infected neurons, inhibits apoptosis, viral transcription, and productive infection, and directly or indirectly enhances reactivation from latency in small animal models. Three anti-apoptosis genes can be substituted for LAT, which …

Nanosecond Pulsed Electric Field (Nspef) Ablation As An Alternative Or Adjunct To Surgery For Treatment Of Cancer, Ru Chen, Xinhua Chen, Stephen J. Beebe
Bioelectrics Publications
Surgery as resection or transplantation remains a fundamental means for cancer treatment and often offers an opportunity for a cure. However, surgery is not always possible because of tumor proximity to blood vessels or ducts or when a patient is not healthy enough to undergo surgery. Application of nanosecond pulsed electric fields (nsPEFs) is a new approach to treat cancer using pulse power technology that was originally designed for military purposes. This novel approach deposits extremely short pulses of high power, low energy electric fields into malignant tissues using electrodes to encompass tumors. Pre-clinical studies show that treatments are effective …
