On the hunt for biomarkers

 

The monitoring and assessment of the symptoms/features of Parkinson’s is a big deal in the research community at the moment.

There is currently a mad hunt for ‘biomarkers’ – reliably measurable physical characteristics – that could help not only with the assessment of individuals living with the condition, but could also aid in the running of clinical trials by providing additional measures of efficacy/benefit.

Recently an interesting perspective was written by some of the leading researchers in this field.

In today’s post, we review what the perspective outlined, and we will discuss other aspects of the biomarker research that need to be considered by the wider Parkinson’s community.

Scientific journals will often invite the research leaders in a particular field of investigation to write a brief journal article that deals with unique view of a common problem.

Articles of this nature are called ‘Perspectives‘.

And recently a very interesting perspective was published in the journal Science on the topic of biomarkers for Parkinson’s.

Title: Finding useful biomarkers for Parkinson’s disease
Authors: Chen-Plotkin AS, Albin R,….a lot of additional authors…, Zhang J
Journal: Science Translational Medicine, 15 Aug 2018, 10 (454), eaam6003.
PMID: N/A

This perspective included a rather long list of a ‘who’s-who’ of Parkinson’s researchers – both academic and industry. Even members of the Michael J Fox Foundation and Verily/Google Life Sciences were included.

The perspective sought to highlight ‘the “ecosystem” of shared biofluid sample biorepositories and data sets will focus biomarker efforts in Parkinson’s‘. It is a very enlightening read, one that begs for reader responses. But sadly the article is behind a ‘pay wall’, and so many in the Parkinson’s community won’t be able to provide any thoughts or feedback.

Shame.

But not to worry, we can discuss the matter here. And the best place to start that discussion is with the obvious first question:

What is a biomarker?

A biomarker is an objectively measurable physical characteristic associated with a condition. It is a biological component of a condition that correlates with that condition in some way. For example, the DaTscan brain imaging technique provides a ‘biomarker’ for Parkinson’s by measuring the amount of dopamine re-absorption in the brain. By labelling the dopamine neurons with a radioactive marker, we can quantify the levels of dopamine activity in a person.

What did the perspective say about biomarkers for Parkinson’s?

Don’t get mad! Get NAD!

Recently researchers have provided very interesting evidence that a form of vitamin B3, called Nicotinamide Riboside, may have beneficial effects for Parkinson’s.

Their data suggests that nicotinamide riboside was able to rescue problems in mitochondria – the power stations of cells – in both fly and human cell-based models of Parkinson’s.

And the results also suggest that this treatment could prevent the neurodegeneration of dopamine producing neurons.

In today’s post, we will discuss what nicotinamide riboside is, what is does in the body, how it may be having its beneficial effect, and we will consider the pros and cons of taking it as a supplement.

We have a serious problem in biomedical research at the moment.

Serious for ‘planet research’ that is (Good for ‘planet patient’! – click here to understand this sentence).

The problem is very simple: there is too much research going on, and there is now too much information to be absorbed. 

There has been an incredible increase in the number of research reports for ‘Parkinson’s’:

For Parkinson’s research alone, every day there is about 20 new research reports (approximately 120 per week). It used to be the case that there was one big research report per year. Then progress got to the crazy point of one big finding per month. And now things are ‘completely kray kray’ (as my 5 year old likes to say), with one new major finding every week!

On top of this, everyday there are new methodology reports, new breakthroughs in other fields that could relate to what is happening in PD, new clinical trial results, etc… The image below perfectly represents how many researchers are currently feeling with regards to the information flow:

Don’t get me wrong.

These are very exciting times, big steps are being made in our understanding of conditions like Parkinson’s. It’s just that it is really hard keeping up with the amazing flow of new data.

And this is certainly apparent here on the SoPD website. Occasionally, a few days after I publish something on a particular topic on the SoPD website, a fascinating new research report on that same topic will be published. When I get a chance to read it, I will sometimes add an addendum to the bottom of a post highlighting the new research.

Every now and then, however, the new research deserves a post all of its own.

Which is the case today.

A week after I published the recent Vitamin B3/Niacin post, a new study was published that dealt with a different form of Vitamin B3, called Nicotinamide Riboside. And the results of that study were really interesting.

Wait a minute. Vitamin B3 comes in different forms?
