The trans-omics of -omics

~ Simon ~ Leave a comment

# # # #

“Precision medicine” is an emerging model of therapeutic intervention in which treatment options are tailored to a specific subtype of a condition or even on an individual patient-based metric that involves an intergrated analysis of his/her comprehensive “-omics” data.

Many different methods of stratifying patients have been proposed and many of them involve adding the word “-omics” to the end of their labels. But these efforts may start to pay big dividends in clinical trials exploring potentially disease modifying therapies in the not too distant future, including in the case of Parkinson’s.

In today’s post, we will look at one such clinical study exploring better patient stratification in Parkinson’s.

I think it all started with Ronald Regan.

But I’m not really too sure.

Or more specifically, not Reagan himself, but rather the 1980s conservative radio broadcaster Paul Harvey.

You see, Harvey was the person who apparently came up with the portmanteau “Reaganomics“. People liked the play on words and thought that it was a clever little label to explain a rather complex subject. But the name kicked off a barrage of imitators with every man and his dog coming up with their own version of -omics.

And scientists really got carried away with the adoption of different kinds of -omics. Every field of research it seems has continuously been inventing new “-omics”. There’s even a wikipedia page for all the different kinds of -omics, and their use has changed our speecheomics (and yes, that really is an actual word).

I am used your posts having odd starting points, but where exactly is this intro going?

Well, I needed to introduce that idea of “-omics” in order for the rest of this post to work.

Oh I see. So what do we mean by -omics?

Disease modification-ish

~ Simon ~ Leave a comment

# # # #

Semantics matters – particularly regarding our communication on ideas like “disease modification” for neurodegenerative conditions.

There is a big difference between “disease eradication” (zero worldwide incidence), “disease correction” (the halting/reversing of progression) and “disease modification” (improving the trajectory of disease).

Recently, researchers in Japan have demonstrated “disease modification” in motor neuron disease with a form of vitamin B12.

In today’s post, we will review this new research and discuss how it could be relevant to Parkinson’s.

During labourious household chores (think: washing the dishes, hanging laundry, or spending time with my daughter), I am usually listening to an audiobook or podcast. One favourite podcast is that of Dr Lex Fridman – an AI researchers at MIT who interviews interesting individuals and discusses a broad range of topics (from neuroscience to weird stuff like aliens, and the meaning of life often gets dragged in as well).

In episode #158, Lex spoke with Zev Weinstein (15 year old son of Prof Eric Weinstein) and I was really struck with how eloquently this young man spoke about philosophy and science, but also the communication of ideas.

Source: Youtube

And at one point in the discussion, Zev said: “Many underestimate the extent to which language and communication really impacts and shapes the ideas and thoughts that are being communicated, and I think if we are willing to accept imperfect labels to categorize particular people or thoughts, in some sense we are corrupting an abstraction in order to represent it and communicate about it. And I think, as we have discussed, those abstractions are particularly important when everything is on fire” – Zev Weinstein (18.03 minutes into the video). The interview occurred in early 2021 around the events of 6th January, hence the “everything on fire” reference.

But the words on “corrupting an abstraction in order to represent it and communicate about it” resonated with me.

And it got me thinking.

Thinking about what?

At the end of each month the SoPD writes a post which provides an overview of some of the major pieces of Parkinson’s-related research that were made available during October 2022.

The post is divided into 10 parts based on the type of research:

# # # #

So, what happened during October 2022?

In world news:

6th October – An open source platform (called “MatchMiner“) which matches genomically profiled cancer patients to precision medicine drug trials is presented (Click here and here to read more about this).

 

7th October –  Neuroscientists report experimental MRI results suggesting that brain functions operate non-classically and their data may support the idea of quantum mechanisms being involved in consciousness as the signal pattern declined when human participants fell asleep (Click here to read more about this).

 

16th-23rd October – The 20th National Congress of the Chinese Communist Party is held. Xi Jinping is elected as General Secretary of the Chinese Communist Party by the Central Committee, beginning a third term as the leader of China.

 

20th October – UK Prime Minister Liz Truss resigned after 45 days in the role.

 

28th October – Elon Musk completed his $44 billion acquisition of Twitter.

 

In the world of Parkinson’s research, a great deal of new research and news was reported:

In October 2022, there were 902 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (9786 for all of 2022 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).

PWP: Parrots with Parkinson’s?

~ Simon ~ 2 Comments

# # # #

Lewy bodies are densely packed aggregates of proteins and lipids that can be found in some neurons in the brain of many people with Parkinson’s. They have long been considered a cardinal feature of the Parkinsonian brain.

To date, humans are the only species that have displayed evidence of Lewy bodies.

But very recently new data has suggested that Lewy body-like pathology might not be so human-specific.

In today’s post, we will discuss what are Lewy bodies are and explore the new research report suggesting that they might not be unique to humans.

The yellow-crowned parrot are remarkably similar to humans.

They have a lifespan of 60 to 80 years (in captivity; 20 to 30 years in the wild), and they are monogamous in their pairing, with pairs often remaining together for life. And they are rather vocal (but curiously they don’t have vocal cords).

Ok, their courtship is slightly different to humans (it involves lots of bowing, drooping, flicking of wings, raising of feet, and dilating of pupils) and chocolate is extremely poisonous to them.

But by and large, they are remarkably similar to us (at least as far as birds go).

Great, but what does any of this have to do with Parkinson’s?

GCase: Mutants matter?

~ Simon ~ 7 Comments

# # # #

Tiny genetic variations in a region of DNA called the GBA gene are associated with an increased risk of developing Parkinson’s. The information in the GBA gene provides the instructions for making an enzyme (called GCase) which is involved with waste disposal inside of cells.

Individuals with Parkinson’s who carry a variation in their GBA gene typically have low levels of GCase activity, so researchers have been attempting to identify therapeutic molecules that will enhance the level and activity of GCase as an approach towards slowing the progression of Parkinson’s.

Recently, however, new research has provide novel insights into how the biology of GCase pathway may be affected in individuals with Parkinson’s who carry a GBA genetic variation. 

In today’s post, we will explain what the GBA gene and GCase enzyme are, review the new research, and consider the potential implications of these findings.

Professor David Sulzer is one individual in the scientific research community who truly fascinates me.

In addition to being at the absolute top of his game academically (he is a professor of Psychiatry, Neurology, Pharmacology at Columbia University and maintains a very large research group investigating neurodegenerative conditions), he is also a composer and musician with a discography that any professional artists would be extremely proud of (his recording alias is Dave Soldier).

He’s also written books (for example “Music Math and Mind“).

Where he finds the time to do all of these thing I do not know, but I really like the combination of art and science.

Oh, and did I forget to mention the Thai Elephant Orchestra?

I’m sorry: The what?!?

Just watch:

They have released three CDs and the band grew up to 14 elephants.

Fascinating, but what does this have to do with Parkinson’s?

LRRK2 inhibition represents one of several biological approaches to slowing the progression of Parkinson’s that is currently being clinically tested.

Leading the charge in the development of LRRK2 inhibitors is a biotech company called Denali Therapeutics (in partnership with Biogen).

Recently, the company provided news on the immediate future clinical development plans for their lead molecule BIIB122.

In today’s post, we will look at what is going to happen next for LRRK2 inhibition.

Year in review: 2021

~ Simon ~ 3 Comments

# # # #

As with the preceding year, 2021 proved to be challenging due to the continuing COVID-19 pandemic (and it is not over yet). Vaccines were rolled out with remarkable speed, but equally new variants of the virus popped up and have kept Governments and health regulatory bodies on their toes.

An amazing feature of the last two years has been the response to the pandemic from the research community – not only in sequencing novel variants and testing new vaccines – but also in terms of keeping research projects ongoing in other fields of science. Despite everything pandemic-related, there has been significant progress in areas like Parkinson’s research.

In today’s post, we will consider three big Parkinson’s-related research takeaways of 2021 (based on our humble opinions here at the SoPD), and then we will provide an extended overview of some of the important discoveries and pieces of news from the last 12 months (Be warned: this will be a long post).

There are 52.143 weeks in a year, which equates to:

  • 365 sun rises and sunsets
  • Approximately 13.3 lunar orbits (Source)
  • 8 760 hours
  • US$93.86 trillion in global gross domestic production (nominal terms; 194 economies in 2021 – Source)
  • 525 600 minutes
  • 29.2 tons of adenosine triphosphate (ATP) production and recycling (per person – based on an average 80kg individual)
  • 31 622 400 seconds (Source)
  • Approximately 35 million heart beats and  8.4 million breaths

Basically, ample time and resources to do some useful stuff (beyond simply binging “Squid games” on Netflix or playing “candy crunch”).

The last 52.143 weeks have been particularly challenging in many countries due to the ongoing COVID-19 situation. Despite these ongoing challenges, significant progress has been made in the research surrounding Parkinson’s and other neurodegenerative conditions in 2021.

Below we will discuss three of the main research-related pieces of news for Parkinson’s (as determined by the team here at SoPD HQ), before providing a month-by-month overview of the note worthy events.

Administrative: No more Meta

Administrative news: The Science of Parkinson’s page on Meta has been removed.

# # # #

Source: Gadgethacks

Hi folks,

This is just a quick post to say that the SoPD page on Meta (formerly Facebook) has been removed.

This is not a ‘holier-than-thou’ protest, but rather a philosophical difference of opinions: We simply do not want to be associated with them.

Facebook went in the wrong direction some time ago. If the company now wishes to think that people will trust them with their financial details (their libra project) in the wake of the Cambridge Analytica disaster or that a name change will solve everything (remember Blackwater, it became Xe Services in 2009, then Academi in 2011,…), then good for them.

I really fear that they are not even trying to solve the issues that plague their business as they now seek to offer the fully immersive experience of “the metaverse”. In all likelihood, the move will only supercharge the problems.

I wish them well, but SoPD will not be associated.
