Liposome research meets nanotechnology to improve cancer treatment

Posted on by

In the race to find more effective ways to treat cancer, Boise State University biophysicist Daniel Fologea is working outside the rules of general mathematics that say one plus one equals two. In his world, one plus one adds up to a whole lot more.

While radiotherapy can precisely target just the tumor site, systemic chemotherapy spreads a wide net, sending drugs speeding throughout the entire body in an attempt to kill cancer cells while also killing many healthy cells. Neither of these methods is highly effective when applied alone, therefore separated sessions of chemo and radiotherapy are required when fighting against solid tumors.

Reports have shown that ideally, both methods would be employed at the same time. But doing so produces levels of toxicity that often are deadly. To reduce the remote toxicity inherent to chemotherapy, the drugs can be administered into solid tumors by using liposomes, which are nanoscale vesicles made from fats and loaded with anti-cancer drugs. Liposomes self-accumulate within the tumor but the loaded drugs will be released very slowly from their encasing.

A new patent awarded to Fologea, a professor in the Department of Physics, and co-researchers from the University of Arkansas in August 2014 holds promise of a way to combine the oomph of chemotherapy with the precision of radiotherapy, without harm to healthy cells.

In the new approach, said Fologea, "The liposomes are designed to release their precious cargo upon exposure to x-ray. Not only does this target where the medication goes, it also allows for a huge concentration of the drug to be released at once at the tumor site, thus increasing its efficacy. In addition, this combined modality of treatment employing concomitant radio and chemotherapy is supra-additive, which means it is several times more efficient than each therapy applied alone."

Here's how it works: liposomes have small scintillating nanoparticles embedded within them. When hit with the x-ray, they emit ultraviolet (UV) light. UV light triggers the release of Ca2+ entrapped into a photolabile cage inside the liposomes. The free Ca2+ activates an enzyme called phospholipase A2 that starts chewing the fats in the wall of the liposomes and triggers the fast release of the drug.

Now that they have a patent on the technique, researchers still expect several years of testing before the method is approved and available for cancer patients.

In the meantime, Fologea completed the initial phase of another method to provide similar results by using only materials previously approved by the FDA for treatment of cancer and other diseases. This approach will pave the way for earlier translational studies.

Working with Boise State biology professor Cheryl Jorcyk, he is looking for ways to put antibodies on the surface of the liposome, allowing them to recognize and attack cancer cells that are circulating in the body. A distinct approach to develop liposomes useful for treatment of diabetes is under development with Boise State biology professor Denise Wingett.

Livermore lab names new associate director for Engineering

Posted on by

LIVERMORE -- Lawrence Livermore Laboratory on Sept. 12 announced the hiring of Anantha Krishnan as its new associate director for engineering, concluding a nationwide search.

In his new role, Krishnan will lead an organization of about 1,600 employees. Since arriving at the lab in 2005, Krishnan has held multiple scientific and management positions, specializing in areas such as additive manufacturing, biomedical engineering and advanced sensor devices and systems, according to a lab news release.

At Livermore, Krishnan has served as the deputy associate director of the lab's Engineering Directorate and as the program director for biosecurity, as well as the acting program director for counterterrorism. He also served as the director of research in the Center for Micro- and Nano-Technology, and as director for the Office of Mission Innovation.

Prior to working for the lab, Krishnan was a program manager at the Defense Advanced Research Projects Agency, where he was awarded the Medal for Exceptional Public Service by the Secretary of Defense in 2005.

Krisnan replaces retiring lab Associate Director Monya Lane.

WSU approves medical-school plans despite UW objections

Posted on by

SPOKANE Washington State Universitys board of regents on Friday unanimously approved the administrations controversial effort to start a new medical school in Spokane, citing the dire need for more doctors in the state.

The easy path for us to take would be to support the status quo, Regent Scott Carson said. The data tells us theres a need, and we should move forward to fill that need.

WSUs plan is opposed by the University of Washington, which operates the states only publicly funded medical school.

While approving WSU President Elson Floyds pursuit of the independent medical school, the regents said the university should continue its partnership with the University of Washingtons WWAMI program, which trains doctors for the states of Washington, Wyoming, Alaska, Montana and Idaho.

There is no question that the excellence of the University of Washington program is a real blessing to the state, Regent Laura Jennings said. We need both WWAMI and a new medical school to meet the needs.

The boards approval came a day after a consulting firm said WSU is well-positioned to start a medical school. The consultants report found that Washington suffers from a shortage of doctors, especially outside the Seattle metropolitan area, and that shortage is likely to grow.

Nearly half of the states physicians are in King County, the study said, greatly exceeding its 29 percent share of the states population. Of Washingtons 39 counties, 18 have 10 or fewer physicians per 10,000 people. King County, in contrast, has more than four times as many.

State Sen. Michael Baumgartner, R-Spokane, said he will push for a second medical school in the Legislature.

The ability of the state to have another accredited medical program for only an initial investment of $2.5 million gives the Legislature something to strongly consider, Baumgartner said.

I intend to find a model where University of Washington and Washington State University do it together, he said. I will not allow this to become the Apple Cup of medical schools.
