Scientists
had originally thought they could create a “magic bullet” to patrol for
cancer cells in the body, but only 5% of injected nanoparticles reach
the targeted tumor using current delivery techniques. A Johns Hopkins
University scientist is now working on techniques to specify
nanoparticle size and shape and improve the chances that the drug will
find its target.

Doctors have long known that treating patients with multiple cancer drugs often produces better results than treatment with just a single drug. Now, a study from Massachusetts Institute of Technology shows that the order and timing of drug administration can have a dramatic effect.

In
order to reactivate silenced genes, a cell needs to remove certain
“off” markers called methyl groups from the DNA. Scientists have
recently shown that this process involves an intermediate step and an
enzyme that also plays a role in the development of blood cancer. The
finding could lead to new ideas for cancer-fighting therapies.

As
vacationers prepare to spend time outdoors this summer, many of them
will pack
plenty of sunscreen in hopes it will protect their bodies from
overexposure,
and possibly from skin cancer. But researchers at Missouri University of
Science and Technology are discovering that sunscreen may not be so safe
after
all.

Researchers
have taken advantage of cells' physical properties to develop a new
instrument that slams cells against a wall of fluid and quickly analyzes
the physical response, allowing for the identification of cancer and
other cell states without expensive chemical tags.

Both radiation and many forms of chemotherapy try to kill tumors by causing oxidative stress in cancer cells. New research from the University of Southern California on a protein that protects cancer and other cells from these stresses could one day help doctors to break down cancer cells' defenses, making them more susceptible to treatment.

Using light-harvesting nanoparticles to convert laser energy into plasmonic nanobubbles, researchers at Rice University, the University of Texas MD Anderson Cancer Center, and Baylor College of Medicine are developing new methods to inject drugs and genetic payloads directly into cancer cells. In tests on drug-resistant cancer cells, the researchers found that delivering chemotherapy drugs with nanobubbles was up to 30 times more deadly to cancer cells than traditional drug treatment.

Drugs made of protein have shown promise in treating cancer, but they are difficult to deliver because the body usually breaks down proteins before they reach their destination. To get around that obstacle, a team of Massachusetts Institute of Technology researchers has developed a new type of nanoparticle that can synthesize proteins on demand.

Nanotechnology offers powerful new
possibilities for targeted cancer therapies, but the design challenges
are
many. Northwestern
University scientists now
are the first to develop a simple but specialized nanoparticle that can
deliver
a drug directly to a cancer cell's nucleus—an important feature for
effective
treatment.

Targeted therapeutic nanoparticles that accumulate in tumors while bypassing healthy cells have shown promising results in an ongoing clinical trial, according to a new paper. The nanoparticles feature a homing molecule that allows them to specifically attach cancer cells, and are the first such target particles to enter human clinical studies.
