Researchers identify new combination therapy that promotes cancer cell death

Researchers at the University of Pennsylvania School of Medicine identified a combination therapy as a way to sensitize resistant human cancer cells to a treatment currently being tested in clinical trials They propose that the therapy may help to selectively eliminate cancer cells while leaving healthy cells intact, providing a cancer treatment with fewer side effects.

Eye lens and nose cells for smelling have same origin

A team of researchers at Umeå University in Sweden have discovered a unique mechanism by which the same signal molecule determines the formation of the both the lens of the eye and the olfactory cells of the nose.

White blood cells are picky about sugar

Biology textbooks are blunt - neutrophils are mindless killers. These white blood cells patrol the body and guard against infection by bacteria and fungi, identifying and destroying any invaders that cross their path. But new evidence, which may lead to better drugs to fight deadly pathogens, indicates that neutrophils might actually distinguish among their targets.

Magnetic nano tweezers show how cancer drug works

The annoying bulges of an over-wound telephone cord that shorten its reach and limit a caller's motion help to explain why drugs called camptothecins are so effective in killing cancer cells, according to investigators at St. Jude Children's Research Hospital and Delft University of Technology.

Scientists discover protein instrumental to brain development and repair

Scientists at Children's National Medical Center have demonstrated conclusively that a specific protein and its signaling activity are instrumental in myelination and remyelination, processes essential to the creation and repair of the brain's white matter.

New working principle in cancer treatment

Due to defects in chromosomal distribution, a majority of tumor cells would not be able to survive were it not for a trick that cancer cells have developed to avoid this chaos in the genetic material.

Biomira files NDA for novel inhibitor of hypoxia-inducible factor-1 alpha

Biomira Inc. has announced that it has submitted an investigational new drug (IND) application to the U.S. Food and Drug Administration for PX-478. PX-478 has been shown in preclinical studies to inhibit hypoxia-inducible factor (HIF)-1 alpha, a protein that controls the transcription of a number of genes whose products are important for tumor growth and survival.

RNA molecules can orchestrate gene activity across vast portions of the human genome

Large, seemingly useless pieces of RNA - a molecule originally considered only a lowly messenger for DNA - play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.

Link between ciliary signaling and cancer

Submarines have periscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.
