Stage IV cancer cells even more susceptible to grape seed extract than stage II

When the going gets tough, grape seed extract gets going: A University of Colorado Cancer Center study recently published in the journal Cancer Letters shows that the more advanced are colorectal cancer cells, the more GSE inhibits their growth and survival. On the other end of the disease spectrum, GSE leaves healthy cells alone entirely.

Researchers report novel charge zipper principle used by proteins to form functional units

Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane.

New math model may help predict colon cancer resistance to chemotherapy

Scientists may be able to better predict which patients with colorectal cancer will respond to chemotherapy using a new mathematical model that measures the amount of stress required for a cancer cell to die without harming healthy tissue. The results of this study are published in Cancer Research, a journal of the American Association for Cancer Research.

Stress in adolescence can cause severe mental illness in young adulthood

Working with mice, Johns Hopkins researchers have established a link between elevated levels of a stress hormone in adolescence — a critical time for brain development — and genetic changes that, in young adulthood, cause severe mental illness in those predisposed to it.

Scientists identify new mechanism for schistosomiasis-bladder cancer connection

About 200 million people across 75 of the poorest countries in the world are now infected by the blood parasite Schistosoma haematobium (S. haematobium). The infection causes severe urogenital disease, but also causes bladder cancer in a number of patients and why this occurs is not clear.
