Study identifies mechanism that explains how cancer cells spread to the lymph nodes

Metastasis is responsible for 90% of deaths in patients with cancer. Understanding the mechanisms responsible for this process is one of the top goals of cancer research. The metastatic process involves a series of steps chained where the primary tumour invades surrounding tissues and ends spreading throughout the body. Ones of the first tissues undergoing metastasis are the lymph nodes surrounding the tumour.

Pten gene can also fight against obesity, ageing process

This result, obtained after five years' research, is published in leading journal Cell Metabolism. The authors, led by Manuel Serrano (CNIO), believe it will open the door to new therapeutic options not only against cancer, but against obesity and even the ageing process.

Cdk1 molecule plays an important role in mammalian egg maturation

Women who have eggs that cannot mature will not become pregnant, and they cannot be helped by in vitro fertilization (IVF). Now researchers at the University of Gothenburg, Sweden, have identified a molecule called Cdk1 that has an important function for mammalian egg maturation. In the future this could lead to an increased rate of successful IVF.

Vitamin E may lead to thinning and weakening of bones: Study

From studies in laboratory animals it was found that the most common form of vitamin E stimulates the generation of bone-degrading cells. Scientists who carried out the research in Japan are now calling for their results to be followed up in humans.

Researchers identify mechanism by which cannabis affects working memory

A deterioration of working memory is observed in people who consume drugs containing cannabinoid compounds found in cannabis leaves and buds. A team led by Giovanni Marsicano in collaboration with a team led by Xia Zhang, has recently identified the mechanism by which these substances affect working memory.

Researchers discover critical placental niche cell and signaling pathway

UCLA stem cell researchers have discovered a critical placental niche cell and signaling pathway that prevent blood precursors from premature differentiation in the placenta, a process necessary for ensuring proper blood supply for an individual's lifetime.

Cyclotides discovery may open up new possibilities for immune suppression

A team of researchers at the MedUni Vienna, together with scientists from the University Hospital of Freiburg, has decoded a mechanism in cyclic plant peptides, known as cyclotides, from the family of coffee plants (Rubiaceae) that could open up new possibilities for immune suppression.

Researchers refute widely accepted hypothesis about causative step in ALS

In science, refuting a hypothesis can be as significant as proving one, all the more so in research aimed at elucidating how diseases proceed with a view toward preventing, treating, or curing them. Such a discovery can save scientists from spending precious years of effort exploring a dead end. In a study published in the Proceedings of the National Academy of Sciences, Munich-based researchers refute a widely accepted hypothesis about a causative step in neurodegenerative conditions.

Scientists discover new way to measure success rate of IVF embryos

Scientists at University College Dublin have discovered a new way of measuring the potential success rate of an embryo before it is transferred back into the womb during in vitro fertilisation (IVF).

First clinical assessment of how interferon fights infections in people

A drug once taken by people with HIV/AIDS but long ago shelved after newer, modern antiretroviral therapies became available has now shed light on how the human body uses its natural immunity to fight the virus—work that could help uncover new targets for drugs.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

Combined bioactive peptides successfully stimulate wound healing

Researchers have combined bioactive peptides to successfully stimulate wound healing. The in vitro and in vivo study, published today in PLoS ONE, demonstrates that the combination of two peptides stimulates the growth of blood vessels and promotes re-growth of tissue. Further development of these peptides could lead to a new treatment for chronic and acute wounds.

New model to evaluate probiotic survival in the gut

Functional foods containing bacteria with beneficial health effects, or probiotics, have long been consumed in Northern Europe and are becoming increasingly popular elsewhere. To be of benefit, however, the bacteria have to survive in the very hostile environment of the digestive tract.

Scientists create first 3-D living tissue model of glioma

Brown University scientists have created the first three-dimensional living tissue model, complete with surrounding blood vessels, to analyze the effectiveness of therapeutics to combat brain tumors. The 3-D model gives medical researchers more and better information than Petri dish tissue cultures.
