What is Proteomics in Proximity?

Proteomics in Proximity discusses the intersection of proteomics with genomics for drug target discovery, the application of proteomics to reveal disease biomarkers, and current trends in using proteomics to unlock biological mechanisms. Co-hosted by Olink's Dale Yuzuki, Cindy Lawley and Sarantis Chlamydas.

Welcome to the

Proteomics in Proximity podcast, where

your co hosts, Dale Yuzuki, Cindy

Lawley and Sarantis Chlamydis from Olink

Proteomics talk about the intersection of

proteomics with genomics for drug target

discovery, the application of

proteomics to reveal disease

biomarkers, and current trends in using

proteomics to unlock

biological mechanisms. Here we have

your hosts Dale, Cindy, and

Sarantis. Welcome from the trade show floor

of ASHG 2022.

American Society of Human Genetics

in Los Angeles.

And we have all three of us in the

same place and at the same time.

So I have to remember not to look at

you, but to look at

you. But we had a

really and are having an awesome time.

And I want to start with

talking about the workshop that

Olink put on. So who wants to start talking

about the workshop? I'll do it.

Go for it. Yeah. So,

the workshop was an

industry session put on,

by Olink. And we

thought, some people thought we would have

only 50 people. I thought over

there for a presentation by Chris

Wheland, who was

discussing the work that he,

Melissa Miller from Pfizer and

Lyndon Mitnaul from

Regeneron, spearheaded around

bringing these groups together. That

several of these pharma proteomics partners

came out of sequencing

consortium that they brought on another

seven, folks, and then

really built this proteomic data set that

will be public.

What Cindy's talking about is the

UK biobank Plasma Proteome

project. Pharma proteomics. Pharma. I keep

saying Plasma Proteome project, but it's a

Pharma Proteome project.

And Chris, right, was spearheading

it, he organizing it, and here it is.

He's seeking at an industry workshop. So

what did he talk about?

So he had several great

points, but much of it was around this

structure of building a

pQTL data set for a systematic

approach to therapeutic target discovery.

But he also talked, uh, about a couple

of examples within those

data. And what I really liked was where

he looked at... Stratifying

with polygenic risk and then

looking, doing a biomarker study

and using the genetics in a different way

than integrating with looking

at correlations to proteins. Which I

quite like those examples because there are

lots of different ways that genetics can add

value to how you structure your proteomics

studies to improve your power to detect the

relationship between genetics and

disease. So here we had a full

house, right? He's walking

through the goals of the

UKB Pharma Proteome

project. Well done. And then he

had, what,

samples worth of data. Did he talk

really much about the data?

So, he...

like I said, he dug in a little bit

about examples like PCSK9

was an example. I'm trying to

remember if on this talk, he talked about

the ABO blood group. He often uses

that. These are examples that are in that

bioRxiv preprint. And

I'm going to just give away a little

behind the scenes thing I heard last night,

and that was that the Pharma Proteomics

partners were digging the

idea of calling it the UK

OPP, "be down with

the OPP", especially since we're in Los Angeles.

So I thought that was fun, like putting a

Olink in there. But alas,

not to be, not to be

the "Olink Proteomics project"

I did dig

that whole, uh, link to the rap world

sitting here in LA. And when you're talking

about last night, you were actually in a

meeting then? No, we actually had a

celebratory dinner. Oh, how neat. It was

beautiful, really, to see these

people I haven't met in person before

sure. And talked to them. I mean,

that's the advantage of an in person

conference, right? For many of us, it's

like the first time in three years we've

seen each other in person for ASHG,

right? That's right. And actually, since

we're talking about the, ah,

UKB-OPP okay,

PPP. Uh, we actually have,

Evan Mills over here off to

my left. I'm going to drag him in and have

him just say a few words about

he went with me to that dinner. We had

several people from Olink, at that

dinner. And so yeah. Evan, can you just say

hello? And a little bit about your role.

close to the microphone and inside it. Yeah.

there you go. I feel like I'm being let into

the circle of trust here. Thank you so

much, my friends.

Yeah. So this meeting has been incredible.

Uh, my role, I'm the VP of our Global

Strategic Account Team, and

that essentially means

where is Olink going to make the most

impact in the world, trying to make sure

we find those opportunities and work very

closely with those partners. So the

UK Biobank Pharma Proteomics Project

clearly falls into that. And I've had the

privilege of getting to know

and work very closely with the 13

companies. And last night was a bit of a

culmination where everyone sat around the

dinner table, raised the glass.

"Congratulations about the success of the

project". All of the data is actually

going to be coming imminently.

...So it was

really one of those pinch yourself

moments, uh, to be sitting with

I mean there are so many thought leaders in the

space all around one table.

Mark McCarthy. Slavé Petrovski

Chris Whelan. Erin

Smith. Erin Smith. Melissa

Miller. It was just really an amazing

opportunity. So, yeah, it's been a heck

of a meeting. Yeah it has. And

while we're talking about Erin Smith, I

will say Erin Smith's poster, she's at

Takeda. So her poster

here, which used, uh,

proteomics to look at NASH,

won a Reviewer's Choice Award.

I don't know if I'm close enough to the

microphone to actually be recording this,

but just saying that Erin Smith, uh, from

Takeda, her poster that leveraged the

UK Biobank data, won

a Reviewer's Choice Award, and so did Ben

Smith. Sorry, Ben Sun. Erin Smith

and Ben Sun

And of course, the Pharma Proteomics

partners are co-authors on

that. Sun et al paper. Yeah,

I mean, there's a remarkable number. I don't

know if you've described the 19

abstracts and six talks.

We are at a genetics conference and we're a

proteomics company. So I just think this is

a very important future

viewing sign

that uh, the community that's used to

A's, T's, C's and G's are really

opening up to large scale proteomics

and seeing the tremendous impact that

it can have. Sarantis,

as a multi-Omics guy, are you

surprised by this? No, actually

I'm surprised of how many people

and uh, they're talking about the UK

Biobank. I think the

cohort is amazing. We have access and

we have collaborations

with a lot of academic

and pharma companies around these

samples. And the future is here. The future

of genomics is here. Now everybody talks about

the next steps. Proteomics is now

really nice. Genomics. When people

think about genomics, they consider

immediately protomics. We integrate the data

and uh, yeah, they're really

great, great moments to come.

And this question is always what comes

next to discussion for the future?

It was really nice because maybe in

a couple of talks where they

tried discussions and integrations from

Steven Horvath

and really nicely explain that they try and integrate

UK Biobank methylation profiles, and methylation data

and really nicely explain that methylation data

and plasma proteins really correlate to expression of proteins in cells

and really nice correlation between protein levels

and DNA methylation pattern

more than the expression of RNA levels

that seem really nice and

here when you want

to have, um, a better view of

your biomarkers. You have to integrate a

multiomics approach, (different labs

performing) and DNA itself doesn't say

all the truth. Proteins are the

bridge, are the blocks that correlate really

nicely for changes are happening. DNA,

genetics, DNA methylation, epigenetics.

That was a

great, uh, takehome message. From Steve Horvath.

nowadays you're Mr.

Methylation here, right? And at a

genetic conference, there's a lot of

methylation talk, right, in terms of DNA,

RNA, protein and what's regulating the

RNA. I mean, Steven Horvath, he's

talking in the context of UK

biobank, right? And he's giving

this aspiration

wanting methylation data from the UK BioBank

as another -Omic layer.

And then what happens?

All the questions are all

around methylation.

It's like, okay, we know,

we know the - People are excited about that

Pharma Proteome project is going to have

all these great drug targets. We know

it's going to be great biomarkers and all

this great stuff. It's like, okay, well, but

we want something more.

It's the multiomics approach, we're in the era of multiomics, proteomics it's the real bridge

That's the thing... I think that the tool building too.

So I'll also say something else that

um, was just a really exciting

highlight for me was the Allen Award, of

course, a very prestigious ASHG

award that, went to,

Professor Sir Peter Donnelly. He was

knighted in 2019, I

believe. Uh, but he

has been pivotal.

I started at Illumina

during HapMap. So he was a big

leader and proponent for the

approaches that were used in the HapMap

project. And of course, the HapMap project

had like one plate of Caucasian samples,

one plate of Aruba samples,

and half a plate of, ah, each

Han Chinese and Japanese samples.

Right. That was our first swath

at diversity

across, ah, different

ancestral populations.

Uh, and after that, the 1000

Genomes Project, once next generation

sequencing became available. And so all of

that documenting or cataloging

of diversity, he was

pivotal in building out, methods for

analyzing those data. He built

"Structure". Right. So when I was in graduate

school, Jonathan Prichard was one of his

students who built that program.

I think he was a student. I don't think he

was postdoc, I think he was a student. And

this program "Structure" does what?

"Structure"? Actually, I still

see it in most sessions, in at least one

talk in most sessions. Use

of this amazing tool to

essentially take data and

use the data for it to generate, uh,

the number of groups that are represented

by the genetic data. Right. So these are

these dot plots with the different

colors. That's right. Exactly. African in

this dimension. That's right. Asian

in this dimension. Exactly. Yeah.

Beautiful colorful plot

that demonstrates within

this we think there are three

groups or within the data,

letting the data speak for itself rather

than a priori saying. For

me, looking at fish, I was

sampling from eight locations. But if those

eight locations actually only represent

four unique genetic entities,

that says something about how to conserve or

manage fish. But let's go back to Peter

Donnelly. I just want to say what a rock

star he is. And then we can yeah,

just go right ahead. Really want to call out

to this man because he is certainly a

statistical, geneticist statistical analyst.

Right. But

with having that skill, but also

being charismatic and able to

bring people together to

help them see

what's possible with it like being able to

communicate. It just comes down to

communication so often.

And he's such a thought leader here. And so

I was just so excited to see his

and when he told me he was getting an award,

and then I looked up what he was getting an

award, I was just like, he's so humble

and so amazing. The

importance of communicating. Right. The

importance of working with others.

The point I was going to

make before is, as far as the use of

this term Structure, I mean, this

particular program Structure is

that in the UK, people can

say I identify

as sort of I believe my

parentage is Japanese. I have

every reason to believe it. But

genetically it could it be that there

may be some Mongolian in Dale's

background? Who knows? Right.

But then a program like this say

I sign up for "All of U". Right. And

by the way, I went to an

"All of Us" session and it was

fascinating to see that. Yes. Even

though COVID kind of slowed their

enrollment down and slowed the progress

down, they're up and going again.

So I went to joinallofus.org

this morning, and I started the

enrollment. Why, I think they're only

about a half million into their

million sample. Cohorts

and like you mentioned, 50,

right. They're working on getting

great diversity. There was one

talk that talked about engaging, uh,

native American,

uh, native populations,

and they're really emphasizing that. And

there was one particular talk where it was

just how many tribes in

just Alaska, it's like

Well, I mean, there's what is it, how

many ethno linguistic groups in

Africa, right? 54 countries, but like

me of another great

Plenary session, right, where they're

announcing right, genome Centers of

Excellence in Africa. They're getting a

conference in Cape Town in the spring.

Francis Collins we have abstract

submitted to that conference, by the way.

Oh, how cool.

We hope

the emphasis, right, on non

European populations, the emphasis on

diversity, the emphasis on African

genomes I mean, in that one session

they talked about loss of infectivity, they

talked about sickle cell anemia and

just some HIV infections and

some remarkable

disparities in terms

of the number of uh, for example, for

a sickle cell. Right. There are several gene

therapy trials here in the US.

And in Africa? Zero. Ah,

I'd like to double

click back on the all of US program, because

something that I learned here, this

meeting was that it isn't currently set up

in the way that UK Biobank is set

up, uh, with an international

sharing structure, which

I imagine they have good reasons for. But

I think there's a hope that All of

Us will consider creating an international

sharing structure that will enable, if we

build these centers of excellence in Africa,

we want those scientists to be able

to analyze those data or interplay with

those data. Maybe it can't be transferred or

downloaded. But having a federated

sharing environment, having a protected, ah,

sharing environment that allows

insights from those data to then be

transferred, because those investments can

be used globally. Like the, UK Biobank

Project. Sure. I mean, there was

a Tweet, right, that was really popular,

talking about how frequent the UK

Bio bank is popping up. Somebody saying they

felt like every other talk matches the

UK Biobank. It's a great

validation. Cohort right. But

also for

initial findings,

people are still mining those data directly.

I mean, as a grad student, I would imagine

that's a rich data set to have access to and

a lot of sequencing. Right.

I know that you're looking really close to

the new secrets and technologies.

Yeah, well, I mean, Maroon 5,

right? Yeah, we should talk about Maroon 5.

Okay, so it's a gigantic line. I mean, Olink

had our own VIP event. It

was pretty small, right? All

these people lining up to hear Maroon 5

and pictures and stuff like that. But

But why? Why have a

popular band play? Because they

announced two new platforms,

PacBio 15X, the Revio

is 15X the throughput of a Sequel II

The Onso, which is the Omniome

short read platform. You've

got MGI here. You've got

Ultima Genomics here. We've got

Singular Genomics here. We've got Element

biosciences here. All with new instruments,

right. All sort of bringing it to market.

With our own differentiators own

differentiators what do you

think about the cost? Just driving it

down? Just driving it down

now for what does that mean for

Olink? It means great things for

Olink. Why? Because Olink customers

receive the benefit of those lower costs.

Exactly. That ah, they're not held at $6,

a gigabase for

NovaSeq 6000,

as before.

Right.

I have to insert the company line here.

And just say we are not validated currently

on any of these platforms. But we certainly

have collaborations with many of them.

Yes. With

an interest to keep a focus

on how do we continue to drive

down costs in genomics? We see that

correct.

The NovaSeq

X, right? They're announcing $2

a gigabase at the end, toward the end

of 2023, which is fine, and a

new instrument, which they have right here

in the Illumina booth. But you walk over to

MGI, right?

BGI / MGI. They've got a T7,

a dollar-fifty ($1.50)

per gigabase now.

You just say well,

wow, that's pretty remarkable.

That is happening here at this

conference because of all the

different progress with lawsuits

and what have you, Freedom to Operate. But

nonetheless, Ultima

saying we're going to be at $2 a

gigabase come February of next

year. Uh, I went to the Element

talk and it was remarkable,

right, how they're driving down costs and

how they have really high quality.

So one of the interesting things here at

ASHG is science communication,

and of course, with posters, there's some

and it's a remarkable work

being done in lots of places. We have this

thing in our booth, right, with a number of

different posters from the UK biobank.

But I was looking for Cindy's poster and

I couldn't find it because

there are so many people crowded around

it. So Cindy, why don't you tell

us why don't you tell us a little bit

about your poster? Yeah, it was a

bit of a surprise to me, actually, because

there are so many posters. I've not

had a crowd around an

ASHG poster like this

How interesting. In any of the times that I've

presented yourself. That is so cool. It was

really cool. It was cool. So, uh,

things were noticing and someone took a

picture. I thought, would it be great if

someone took a picture? And then there's Dale

taking a picture. I was thinking I should

have worn my other shoes. But anyway,

the

poster is really an

aspirational poster

about the work being done by the UK

Biobank with proteins.

Meaning that, I talk about a

previous proteogenomics project. It's a

little smaller scale on the protein size. So

It's a cohort of cohorts of bringing

together this is the SCALLOP study. Uh, and

then 90 proteins right. And

so I talk about the 90

proteins. How many pQTL discoveries

were made possible by the 30,000 samples,

and then how many of those

from Mendelian Randomization were

able, to have strong

evidence for potential

therapeutic targets. And so if we saw that

same sort of five and a half percent

conversion to potential

therapeutic targets in the UK

BioBank apply that to just

the 1500 proteins that are published

by bioRxiv paper.

That's over 500

potential therapeutic targets. Disease

agnostic across different diseases. So

anything that's going to give pharma,

a more unbiased approach or a

disease agnostic approach to an

evidence to support

consideration of

particular proteins as

targets, I get

excited about that. There

were several people that came,

and I think maybe because of

where it was located, others that were

walking by stopped as well. And so I

got to present it several times, which is

really fun. But an hour and a

half is not enough time for

a

poster session where you

want to see even just

five or ten posters of,

Because there's just

so much space to cover and

you want to have a conversation with each

person presenting it. And so it was

just nice that people took the time

to come.

One particular poster that caught my eye was

one from Takeda, right, that

uses UK Biobank.

Yeah, that's Erin's. Yeah, I think we

mentioned that

when Evan popped his head in, but

yeah, that one that got the Reviewer's

Choice Award

talking about the

potential for these proteins to

suggest something about

the action in Hepatocytes. What are

exosomes? They mentioned in the conclusions,

really, for future,

studies, which is such a hot

topic that people are talking about, but I'm

not seeing a lot of publications yet coming

out. Looking at broad scale

proteomics within the exosome.

I think we have a lot of.

studies that work with small

amounts of protein, Olink

only being able to pick

up protein

signals from a remarkable number of

sample types. And

we're here on the show floor.

There's so much

going on, it's here overhead.

Opening up in fifteen minutes.

The last show

day. Well, any final

thoughts?

Hear from ASHG?

What I can say from my side is, like,

we see a lot of need for liquid

biopsy, for non-invasive

methods, and we see that they,

are correlating with cancers.

Yeah. Mhm, I'd say mine is

the promise of successes, of pre competitive

collaboration, bringing together groups to

have power for large studies. I

think every time we see a success in this

regard, it lays the groundwork for future

potential successes. And I think that if we

can get the lawyers to all agree

on terms, then,

I think that's the hard part is to make sure

that the interest of each of the

partners is respected and we're able to get

benefits from it. But I'm very

optimistic about that. It is

optimistic time. Well, thank you for

joining us. Thank you very much.
