Cancer drug may reduce kidney disease in lupus

A drug that is already being tested as an anticancer agent, especially in lymphoma, may also reduce the kidney disease that is a result of systemic lupus, according to a researcher at Wake Forest University Baptist Medical Center.

New view of chromatin and gene activity

A genome - the DNA instructions for an organism - does not act alone. DNA is packaged with proteins into 'chromatin', which may be more or less tightly condensed. A popular proposal is that active genes are in 'open' chromatin (to allow access to them) and inactive genes are in tightly packed 'compact' chromatin.

Disruption of protein folding causes neurodegeneration, mental retardation

Excess accumulation in brain cells of a fat molecule called GM1-ganglioside (GM1) disrupts the folding of newly assembled proteins into their proper shapes, triggering nerve degeneration and mental retardation in children.

Transthyretin discovery may halt progression of Alzheimer's

In a finding that may cause a dramatic shift in the way scientists and researchers search for a therapy for Alzheimer's disease, a team of researchers led by Jeff Johnson, an associate professor at the School of Pharmacy, has discovered that increased expression of a protein called transthyretin in the brain appears to halt the progression of the disease.

Painful and damaging chemotherapy may one day be a thing of the past

Researchers at the Georgia Institute of Technology and Purdue University have developed nano-sized particles that can target and trick cancer cells into absorbing them.

Childhood leukaemia significantly lower in Asia than in Western countries

The incidence of childhood leukaemia in Britain increased dramatically during the twentieth century. The increase has mainly affected the under-five age group, in whom the risk increased by more than 50 per cent during the second half of the century alone.

New treatment for T-cell acute lymphoblastic leukaemia

IL-7, a hormone-like protein involved in cell-cell interaction, has been associated with increased survival and expansion of T-cell acute lymphoblastic leukaemia (T-ALL).

Study provides insight on how DNA code is turned into instructions for protein construction

A team of scientists from the Hebrew University of Jerusalem and the Weizmann Institute of Science has revealed the structure of a cellular editor that “cuts and pastes” the first draft of RNA straight after it is formed from its DNA template.

Cancers, including colon, prostate, and leukemia, continue to grow unchecked

Many cancers, including colon, prostate, and leukemia, continue to grow unchecked because they do not respond to a signal to die and stop proliferating from Transforming Growth Factor-beta (TGF-b).

Scientist rewarded for breaking down transplant rejection

A scientist from Australia's Monash University who has recently determined the structure of drug that is widely used as an immunosuppressant, will be presented the 2004 Science Minister's Prize for Life Scientist of the Year.

Gene therapy holds much promise for treating aggressive human superficial bladder cancer

Gene therapy that causes the bladder to act like a “bioreactor” to produce and secrete the anti-cancer agent interferon-alpha has shown dramatic benefits in preclinical tests, say researchers at The University of Texas M. D. Anderson Cancer Center.

Researchers uncover how HIV causes abnormalities in antibody-producing cells

HIV wreaks much of its damage by targeting the “orchestra conductor” of the immune system, a key class of T cells—CD4+ T cells—whose destructive relationship with HIV has been well-studied by AIDS researchers.

Japanese research lab to use an IBM supercomputer for protein research

IBM announced today that AIST, a leading Japanese research laboratory, will use an IBM BlueGene/L supercomputer to advance their research in proteins, potentially accelerating breakthroughs in drug design. The BlueGene/L supercomputer has been ranked as the fourth largest supercomputer in the world.
