Viruses may play a role in lung cancer development
Papers presented at the 1st European Lung Cancer Conference, jointly organized by the European Society for Medical Oncology (ESMO) and the International Association for the Study of Lung Cancer (IASLC) in Geneva, Switzerland highlight emerging evidence that common viruses may contribute to the... view more (2008-04-25)

A step forward in virology
The vaccinia virus has a problem: it is a giant among viruses and needs a special strategy in order to infiltrate a cell and reproduce.   view more (2008-04-25)

Dutch researchers at University Medical Center Utrecht and the Hubrecht Institute have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells.   view more (2008-04-24)

Medical College researchers find dinosaur clues in fat
A team of researchers at New York Medical College has discovered why birds, unlike mammals, lack a tissue that is specialized to generate heat.   view more (2008-04-24)

Menstrual blood -- a valuable source of multipotential stem cells?
Researchers seeking new and more abundant sources of stem cells for use in regenerative medicine have identified a potentially unlimited, noncontroversial, easily collectable, and inexpensive source - menstrual blood.   view more (2008-04-23)

A stem cell type supposed to be crucial for angiogenesis and cancer growth does not exist?
Angiogenesis, the growth of new blood vessels, is a central process in diverse physiological and pathological situations such as healing of wounds and traumas, cardiovascular disorders, inflammatory conditions such as rheumatoid arthritis, and in cancer growth.   view more (2008-04-23)

Chemotherapy causes delayed severe neural damage
Cancer treatment with chemotherapeutic agents is often associated with delayed adverse neurological consequences - an occurrence often referred to as "chemobrain" - that may compromise the quality of life of a proportion of cancer survivors.   view more (2008-04-22)

Pathogen virulence proteins suppress plant immunity
Researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues have identified a key function of a large family of virulence proteins that play an important role in the production of infectious disease by the plant pathogen Phytophthora sojae.   view more (2008-04-22)

Cancer cells spread by releasing 'bubbles', according to an MUHC study
A new fundamental mechanism of how tumour cells communicate has just been discovered by the team of Dr. Janusz Rak at the Research Institute of the McGill University Health Centre (MUHC) in collaboration with Dr Guha from the University of Toronto.   view more (2008-04-22)

Inflammation triggers cell fusions that could protect neurons, Stanford research shows
Chronic inflammation triggers bone marrow-derived blood cells to travel to the brain and fuse with a certain type of neuron up to 100 times more frequently than previously believed, according to a new study from the Stanford University School of Medicine.   view more (2008-04-21)

Ovarian cancer stem cells identified, characterized
Researchers at Yale School of Medicine have identified, characterized and cloned ovarian cancer stem cells and have shown that these stem cells may be the source of ovarian cancer's recurrence and its resistance to chemotherapy.   view more (2008-04-18)

Drug compound leads to death of ovarian cancer cells resistant to chemotherapy
In a discovery that may be useful for maintaining remission in chemo-resistant ovarian cancer, Yale scientists report that pre-clinical studies have shown the drug compound NV-128 can induce the death of ovarian cancer cells by halting the activation of a protein pathway called mTOR.   view more (2008-04-18)

Fruit flies show how salmonella escapes immune defenses
Salmonella are wily and obnoxious bacterial invaders--escape artists capable of evading multiple immune responses and causing a harsh and debilitating intestinal infection.   view more (2008-04-17)

Your belly fat could be making you hungrier
The extra fat we carry around our middle could be making us hungrier, so we eat more, which in turn leads to even more belly fat.   view more (2008-04-17)

New type of drug shrinks primary breast cancer tumors significantly in just 6 weeks
A drug that targets the cell surface receptors that play an important role in many types of cancer can bring about significant tumour regression in breast cancer after only six weeks of use.   view more (2008-04-17)

UAB Study Shows Drug May Fight Biliary Cancers
Laboratory studies by University of Alabama at Birmingham (UAB) researchers have shown that the drug triphendiol (NV-196) causes cell death in pancreatic and bile duct cancer cell lines, slows tumor growth and sensitizes tumors to chemotherapy treatments.   view more (2008-04-16)

A potential sugar fix for tumors
Researchers at the Duke School of Medicine apparently have solved the riddle of why cancer cells like sugar so much, and it may be a mechanism that could lead to better cancer treatments.   view more (2008-04-16)

Molecule prompts blood stem cells to help repair heart damage in animal model
Researchers at UT Southwestern Medical Center have for the first time used drug-treated blood stem cells to repair heart damage in an animal model, results that might point to methods for healing injuries from heart attacks or disease.   view more (2008-04-15)

St. Jude discovery offers new avenues to understanding an aggressive form of leukemia
Researchers at St. Jude Childrenˇ¦s Research Hospital have discovered evidence that a series of genetic mutations work together to initiate most cases of an aggressive and often-fatal form of acute lymphoblastic leukemia (ALL).   view more (2008-04-15)

Molecular basis for neurodegeneration in Ataxia telangiectasia
An upcoming paper from Dr. David Wassarman (University of Wisconsin School of Medicine and Public Health) in the May 1 issue of G&D lends new insight into the pathogenesis of neurodegeneration in Ataxia telangiectasia.   view more (2008-04-15)

Penn researchers find targeted therapy combination overcomes treatment resistance in liver cancer
Researchers at the University of Pennsylvania School of Medicine and Abramson Cancer Center reported today at the annual meeting of the American Association for Cancer Research that combining two targeted therapies overcomes treatment resistance in liver cancer cell lines. The team is currently... view more (2008-04-14)

New Scripps Research study finds T-cell multiplication unexpectedly delayed after infection
In a surprising outcome that overturns the conventional wisdom on the body's immune response to infection, scientists at The Scripps Research Institute have shown that T cells do not begin proliferation until up to three days after infection.   view more (2008-04-11)

Computation to unravel how genes are regulated and shed light on how cells become different
A closer alliance between computational and experimental researchers is needed to make progress towards one of biology's most challenging goals, understanding how epigenetic marks contribute to regulation of gene expression.   view more (2008-04-11)

Developing cancer treatments directed at critical developmental pathway
Researchers from the University of Pennsylvania School of Medicine and colleagues discovered that the Notch signaling pathway, which determines the development of many cell types, and is also implicated in some cancers, is not universally essential for the maintenance of stem cells.   view more (2008-04-11)

Embryonic stem cells could help to overcome immune rejection problems
Tissues derived from embryonic stem (ES) cells could help to pacify the immune system and so prevent recipients from rejecting them, the UK National Stem Cell Network Science Meeting will hear today (11 April).   view more (2008-04-11)
