Micromotor fueled by stomach acid effectively delivers gold nanoparticles

Micromotor fueled by stomach acid effectively delivers gold nanoparticles

Researchers at the University of California, San Diego have shown that a micromotor fueled by stomach acid can take a bubble-powered ride inside a mouse. These tiny motors, each about one-fifth the width of a human hair, may someday offer a safer and more efficient way to deliver drugs or diagnose tumors. [More]

Breast and lung cancer patients with low levels of TTP protein have poorer prognosis

Breast and lung cancer patients with low levels of TTP protein have poorer prognosis

Moffitt Cancer Center researchers have found that breast and lung cancer patients who have low levels of a protein called tristetraprolin (TTP) have more aggressive tumors and a poorer prognosis than those with high levels of the protein. [More]
Pancreatic cancer cells know a way to sidestep chemotherapy, reveal Fox Chase researchers

Pancreatic cancer cells know a way to sidestep chemotherapy, reveal Fox Chase researchers

Pancreatic cancer is one of the deadliest forms of the disease. The American Cancer Society's most recent estimates for 2014 show that over 46,000 people will be diagnosed with pancreatic cancer and more than 39,000 will die from it. Now, research led by Timothy J. Yen, PhD, Professor at Fox Chase Cancer Center, reveals that one reason this deadly form of cancer can be so challenging to treat is because its cells have found a way to sidestep chemotherapy.

Scientists identify strong link between beclin 1 gene and triple-negative breast cancer

Scientists identify strong link between beclin 1 gene and triple-negative breast cancer

UT Southwestern Medical Center scientists have identified a strong link between the most aggressive type of breast cancer and a gene that regulates the body's natural cellular recycling process, called autophagy. [More]
Using Cultrex BME 2 reduced growth factor to enable long-term culture of human hepatocytes

Using Cultrex BME 2 reduced growth factor to enable long-term culture of human hepatocytes

AMSBIO reports on the recent publication in Cell [1] by Dr Meritxell Huch, Prof Hans Clevers et al. of ground-breaking research using Cultrex BME2 reduced growth factor (organoid growth matrix) to enable long-term (>1 year) culture of genome-stable bipotent stem cells from adult human liver. These results open up new experimental avenues towards the use of human liver material expanded in vitro as an alternative cell source for disease modeling, toxicology studies, drug testing, regenerative medicine and gene therapy.

Researchers identify molecular pathways that could lead to new therapeutic targets for cerebral malaria

Researchers identify molecular pathways that could lead to new therapeutic targets for cerebral malaria

A drug already approved for treating other diseases may be useful as a treatment for cerebral malaria, according to researchers at Harvard T. H. Chan School of Public Health. They discovered a novel link between food intake during the early stages of infection and the outcome of the disease, identifying two molecular pathways that could serve as new targets for treatment.
