Molecular Origami: Protein Engineering Emerges to Fight Disease


origamiProtein engineer Aaron Chevalier has a hunch that origami — on a smaller scale — could be the future of drug design.

So he and a team here at the University of Washington spend their days designing intricately folded chains of amino acids to create molecules that do not exist in nature. The goal: Create a protein that might bind to a virus like the flu and stop it from infecting cells. Or one that could break up gluten, effectively taming gluten allergies.

“You could imagine a future where we’re able to design an essentially unlimited number of new proteins that basically are the drugs of the future, the vaccines of the future,” said David Baker, a biochemist who leads the university’s Institute for Protein Design.

Naturally, caveats abound.

For one, it’s unclear if our immune systems will accept new proteins they’ve never seen before. They could cause new allergies. The body could reject them. Or they could turn out not to work in real life, even if they look good on a computer screen. And in practical terms, it will likely be years before any of these newly designed proteins make their way to our medicine cabinets.

“Like with any drug, you always have to experimentally test it before you stick it into a person,” Baker said… Read More>>

Chemo Drug in Pregnancy May Cause Early Menopause in Daughters


The University of Edinburgh in the United Kingdom finds that etoposide – a chemotherapy drug used to treat lung cancer, ovarian cancer, leukemia, and lymphoma – may affect the future fertility of unborn baby girls.

Etoposide works by blocking an enzyme, which is necessary for cancer cells to divide and grow into two new cells. If this enzyme is blocked, the cell’s DNA becomes tangled, and the cell can no longer divide.

According to Cancer Research UK, between 1-10 in every 100 people experience infertility due to the use of etoposide.Chemotherapy can stop the ovaries from producing eggs temporarily or sometimes permanently, and some people experience early menopause.

Chemotherapy administration during the first trimester up to 12-14 weeks is often avoided, as it is associated with increased risk of congenital malformations and high risk of spontaneous abortion.

During the second and third trimesters of pregnancy from 4-9 months chemotherapy treatment if considered to be relatively safe for the developing fetus with several studies showing no birth defects in infants born to women receiving chemotherapy at that time.

However, this research shows that etoposide damages the development of lab-grown mouse ovary tissue and affects specialized cells – called germ cells – that lead to egg production. Further studies are needed to observe if the same effect is true in human tissue… Read More>>

‘Feeling Full’ Hormone Increase in Seniors May Explain ‘Anorexia of Aging’


Termed “anorexia of aging,” loss of appetite is common among elderly adults, with around 15-20 percent of seniors experiencing unintentional weight loss as a result.

While loss of appetite in seniors can be driven by emotional issues, such as depression or grief, in many cases, no underlying cause can be found.

Previous research has suggested loss of appetite in the elderly may be down to reduced production of ghrelin – a hormone that tells humans when they are hungry.

However, the new study – conducted by Mary Hickson, professor of dietetics at Plymouth University in the United Kingdom, and colleagues – found the hormone peptide YY may be to blame.

To reach their findings – published in the journal Appetite – the researchers enrolled 31 healthy adults aged 21-92 years, of whom six were over the age of 80.

They note that one major challenge with this research was finding elderly adults free of health problems, but that this was needed in order to assess changes in appetite control, independent of illness… Read More>>

Volunteering Later in Life Can Enhance Mental Health and Wellbeing


Becoming a volunteer later on in life can result in good mental health and wellbeing, according to researchers from the University of Southampton and the University of Birmingham.

However, the study which is published in the BMJ Open online, found these effects did not apply before the age of 40, suggesting that the association with volunteering may be stronger at certain points of the life course. The results also point to the need for further efforts to engage middle aged and older people in volunteering activities.

Researchers from the Southampton Statistical Sciences Research Institute and Birmingham’s Third Sector Research Centre reviewed over 66,000 responses by British adults to questions posed through the British Household Panel Survey (BHPS), now part of the UK Household Longitudinal Study called Understanding Society.

The original Survey, which ran between 1991-2008, asked a range of questions on leisure time activities including the extent of formal volunteering. The Survey also included a validated proxy indicating mental health/emotional wellbeing known as GHQ-12.

Around 21% of respondents said they had carried out some kind of formal volunteering activity with women tending to volunteer more than men.

Across the entire sample, the average GHQ score was the best (lowest) among those who were frequent volunteers and worst (highest) among those who never volunteered… Read More>>
