Proapoptotic Peptide-Mediated Cancer Therapy Targeted to Cell Surface p32

Targeted nanoparticle enhanced proapoptotic peptide as potential therapy for glioblastoma.

Antiangiogenic therapy can produce transient tumor regression in glioblastoma (GBM), but no prolongation in patient survival has been achieved. We have constructed a nanosystem targeted to tumor vasculature that incorporates three elements: (i) a tumor-homing peptide that specifically delivers its payload to the mitochondria of tumor endothelial cells and tumor cells, (ii) conjugation of this h...

Application of a proapoptotic peptide to intratumorally spreading cancer therapy.

Bit1 is a proapoptotic mitochondrial protein associated with anoikis. Upon cell detachment, Bit1 is released into the cytoplasm and triggers caspase-independent cell death. Bit1 consists of 179 amino acids; for the C-terminal, two thirds of the molecule functions as a peptidyl-tRNA hydrolase, whereas the N-terminus contains a mitochondrial localization signal. Here, we localize the cell death d...

Targeted delivery of a proapoptotic peptide to tumors in vivo.

RGD peptides recognize the α(v)β(3) integrin, a receptor that is overexpressed on the surface of both tumor blood vessels and cancerous cells. These peptides are powerful tools that act as single antiangiogenic molecules, but recently also have been used for tumor imaging and drug targeting. We designed the molecule RAFT-(c[-RGDfK-])(4), a constrained and chemically defined entity that can be p...

Targeted cancer therapy: review article

Cancer is one of the most dangerous health problems of today modern societies which has an increasing rate especially in developing countries. There are many diverse ongoing treatment attempts trying to defeat cancer. Despite that, scientists have been unable to find a permanent cure for this disease. In many cases although there is a successful first response in patients, cancer cells are fina...
