I HAVE PARKINSON'S DISEASES AND THOUGHT IT WOULD BE NICE TO HAVE A PLACE WHERE THE CONTENTS OF UPDATED NEWS IS FOUND IN ONE PLACE. THAT IS WHY I BEGAN THIS BLOG.

I COPY NEWS ARTICLES PERTAINING TO RESEARCH, NEWS AND INFORMATION FOR PARKINSON'S DISEASE, DEMENTIA, THE BRAIN, DEPRESSION AND PARKINSON'S WITH DYSTONIA. I ALSO POST ABOUT FUNDRAISING FOR PARKINSON'S DISEASE AND EVENTS. I TRY TO BE UP-TO-DATE AS POSSIBLE.

I AM NOT RESPONSIBLE FOR IT'S CONTENTS. I AM JUST A COPIER OF INFORMATION SEARCHED ON THE COMPUTER. PLEASE UNDERSTAND THE COPIES ARE JUST THAT, COPIES AND AT TIMES, I AM UNABLE TO ENLARGE THE WORDING OR KEEP IT UNIFORMED AS I WISH. IT IS IMPORTANT TO UNDERSTAND I AM A PERSON WITH PARKINSON'S DISEASE. I HAVE NO MEDICAL EDUCATION,

I JUST WANT TO SHARE WITH YOU WHAT I READ ON THE INTERNET. IT IS UP TO YOU TO DECIDE WHETHER TO READ IT AND TALK IT OVER WITH YOUR DOCTOR. I AM JUST THE COPIER OF DOCUMENTS FROM THE COMPUTER. I DO NOT HAVE PROOF OF FACT OR FICTION OF THE ARTICLE. I ALSO TRY TO PLACE A LINK AT THE BOTTOM OF EACH ARTICLE TO SHOW WHERE I RECEIVED THE INFORMATION SO THAT YOU MAY WANT TO VISIT THEIR SITE.

Can Baker's Yeast Help Us Understand Parkinson's Disease?

Can Baker's Yeast Help Us Understand Parkinson's Disease?

For years, researchers have used baker's yeast — the same ingredient that make bread rise — as a useful model for human diseases, including Parkinson's disease (PD). The yeast contains proteins similar to a PD-related protein called DJ-1, and new research into how yeast proteins function in a cell may help shine light on PD protein activity, according to findings published in the journal PNAS.

The protein DJ-1 has long been linked with Parkinson's disease, but researchers aren't sure what role the protein plays in the cell. In the study, scientists discovered that the yeast proteins that resemble DJ-1 are important for how cells break down and recycle damaged cell parts, in a process called autophagy.

"Lifespan and autophagy are central processes in the context of both Parkinson's disease and cancer,"Digital Journal reported on the study. "Based on this, the identified proteins provide researchers with a new model to explore."

The results may offer some insight into the role of DJ-1 in the cell, says Brian Fiske, MD, vice president of research programs here at the Foundation. But he cautions that much more research is needed.

"Researchers have long used yeast as lab models, and the jump from yeast to humans is often not a clear one," he says. "However, any new understanding of the players in Parkinson’s is progress toward better therapies.”
