The research – carried out by a group of five institutions, including Einstein, that comprise the Texas Center for Cancer Nanomedicine – could lead to novel ways to diagnose and treat pancreatic and ovarian cancer using nanoparticles.
Nanoparticles are engineered materials that are 100 nanometers or less in size. (A nanometer is one billionth of a meter.) Nanoparticles impregnated with drugs are called nanomedicines.
“We will be investigating nanomedicines for both imaging and treating pancreatic tumors,” said Einstein-Montefiore principal investigator Steven Libutti, M.D., professor and vice chair of surgery at Einstein and Montefiore, director of the Montefiore-Einstein Center for Cancer Care, and associate director for clinical services of the Albert Einstein Cancer Center. “Our part of the consortium is developing nanoparticles that will specifically target unique aspects of the blood vessels found in pancreatic adenocarcinomas and pancreatic neuroendocrine tumors.”
Pancreatic cancer is the fourth-leading cause of all cancer deaths. Currently, there is no test for early detection of the disease, which killed nearly 37,000 people in 2010. Only 5.6 percent of people diagnosed with pancreatic cancer live for five years or longer, according to the National Cancer Institute.
Dr. Libutti has developed mice that are genetically programmed to form pancreatic tumors that mimic those seen in people. These mice will be used for testing a variety of nanoparticle-based drugs produced by other collaborators. Such studies will reveal whether the particles can home in on disease locations and deliver therapeutic benefits. Dr. Libutti’s clinical practice involves the surgical management of patients with cancer, including those with pancreatic cancer. A main focus of his research is the formation of new blood vessels that nourish tumors.
Identifying the most promising nanoparticle-based drugs for pancreatic as well as ovarian cancer will take several years. Clinical trials are not likely to begin until the end of the five-year project.
In addition to Einstein the other institutions that are members of the Texas Center for Cancer Nanomedicine involved in the nanotech consortium are the University of Texas MD Anderson Cancer Center, the University of Texas Health Science Center at Houston, the Methodist Hospital Research Institute, and Rice University.About Albert Einstein College of Medicine of Yeshiva University

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
