New understanding on how Myc gene promotes cancer

Cancer cells need a lot of nutrients to multiply and survive. While much is understood about how cancer cells use blood sugar to make energy, not much is known about how they get other nutrients.

Artificial cells, simple model for complex structure

A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a Penn State researcher.

New test for mysterious metabolic diseases

Scientists at Stanford University School of Medicine have devised a much-needed way to monitor and find treatments for a mysterious and devastating group of metabolic diseases that arise from mutations in cells' fuel-burning mechanism.

New technology rapidly detects tumor response to chemotherapy

New technology developed by Duke University bioengineers can help clinicians more precisely detect whether specific cancer drugs are working, and should give basic researchers a powerful new tool to better understand the underlying mechanisms of cancer development.

Slices of living human brain tissue are helping scientists identify new stroke therapies

Slices of living human brain tissue are helping scientists learn which drugs can block the waves of death that engulf and engorge brain cells following a stroke.

New evidence in support of Warburg theory of cancer

German scientist Otto H. Warburg's theory on the origin of cancer earned him the Nobel Prize in 1931, but the biochemical basis for his theory remained elusive.

Genetic mutation causes familial susceptibility for degenerative brain disease acute necrotizing encephalopathy

Mutation of a gene that helps proteins migrate in and out of the cell's genetic command center - the nucleus - puts some families at higher risk for the degenerative brain disease acute necrotizing encephalopathy (ANE).

Both theories about human cellular aging supported by new research

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells.

Biologist provides new theory on mechanisms that control molecular motors

Biologists have known for decades that cells use tiny molecular motors to move chromosomes, mitochondria, and many other organelles within the cell, but no one has been able to understand what "steers" these engines to their destinations.

Mathematical model shows how organelles function within cells

Cells are filled with membrane-bound organelles like the nucleus, mitochondria and endoplasmic reticula.

Doing the math for membranes

Determining the mechanisms that shape biological membranes has long been a tricky business. Like a factory assembly line, eukaryotic cells are organized into membrane-bound, functional compartments called organelles.

More evidence on why the Mediterranean diet is good for heart

Researchers have discovered one potential mechanism by which briefly cutting off, then restoring, blood flow to arteries prior to a heart attack lessens the damage caused, according to a study published today in the journal Cardiovascular Research.

Researchers identify a potentially universal mechanism of aging

Like our current financial crisis, the aging process might also be a product excessive deregulation.

Scientists develop peptide that converts Bcl-2 protein from a cancer cell's friend to a foe

If you're a cancer cell, you want a protein called Bcl-2 on your side because it decides if you live or die.

Researchers shed new light on genetics of Parkinson's

A new study by Narendra et al. suggests that Parkin, the product of the Parkinson's disease-related gene Park2, prompts neuronal survival by clearing the cell of its damaged mitochondria.

More data released on key diabetes genes

One of the most reliable indicators to predict that a person will develop type 2 diabetes is the presence of insulin resistance.

Maas Biolab scientists validate cyclosporin human neuroprotection

Maas Biolab researchers CSO Eskil Elmer, M.D., Ph.D. and neuroscientist Magnus Hansson, M.D., Ph.D., and colleagues have for the first time ever demonstrated the mitochondrial permeability transition (mPT) or "megapore" occurs in viable adult human neuron mitochondria and the ability of cyclosporin-A to block its formation.

New research reveals key steps in HIV's assault on the brain

Scientists have unraveled in unprecedented detail the cascade of events that go wrong in brain cells affected by HIV, a virus whose assault on the nervous system continues unabated despite antiviral medications that can keep the virus at bay for years in the rest of the body.
