In 2003,
0
13507
1889
2003. godine,
00:15
when we sequenced the human genome,
1
15420
2913
kad smo razložili ljudski genom,
00:18
we thought we would have the answer to treat many diseases.
2
18357
3922
mislili smo da ćemo imati odgovor za liječenje mnogih bolesti.
00:22
But the reality is far from that,
3
22974
2657
No, stvarnost je daleko od toga,
00:26
because in addition to our genes,
4
26782
1921
jer osim naših gena,
00:28
our environment and lifestyle could have a significant role
5
28727
4570
naše okruženje i način života mogu imati značajnu ulogu
00:33
in developing many major diseases.
6
33321
2548
u razvoju mnogih velikih bolesti.
00:35
One example is fatty liver disease,
7
35893
3580
Jedan primjer je bolest masne jetre,
00:39
which is affecting over 20 percent of the population globally,
8
39497
4083
koja pogađa preko 20% stanovnika svijeta,
00:43
and it has no treatment and leads to liver cancer
9
43604
3034
i nema joj lijeka, a vodi do raka jetre
00:46
or liver failure.
10
46662
1423
ili zatajenja jetre.
00:49
So sequencing DNA alone doesn't give us enough information
11
49517
4744
Dakle, sekvenciranje DNK samo po sebi ne daje nam dovoljno informacija
00:54
to find effective therapeutics.
12
54285
2232
za pronalazak učinkovitih terapija.
00:56
On the bright side, there are many other molecules in our body.
13
56541
3756
Dobro je što postoje mnoge druge molekule u našem tijelu.
01:00
In fact, there are over 100,000 metabolites.
14
60321
3980
Zaista, postoji preko 100.000 metabolita.
01:04
Metabolites are any molecule that is supersmall in their size.
15
64325
4296
Metaboliti su bilo koja molekula supermale veličine.
01:09
Known examples are glucose, fructose, fats, cholesterol --
16
69193
4972
Poznati primjeri su glukoza, fruktoza, masti, kolesterol --
01:14
things we hear all the time.
17
74189
1510
ono o čemu stalno slušamo.
01:16
Metabolites are involved in our metabolism.
18
76273
2983
Metaboliti su uključeni u naš metabolizam.
01:20
They are also downstream of DNA,
19
80066
4028
Oni su na nižoj razini od DNK
01:24
so they carry information from both our genes as well as lifestyle.
20
84118
5082
pa nose informacije iz naših gena, kao i stila života.
01:29
Understanding metabolites is essential to find treatments for many diseases.
21
89224
5649
Razumijevanje metabolita je ključno za pronalazak tretmana za mnoge bolesti.
01:34
I've always wanted to treat patients.
22
94897
2212
Oduvijek sam željela liječiti pacijente.
01:37
Despite that, 15 years ago, I left medical school,
23
97934
3858
Unatoč tome, prije 15 godina, napustila sam medicinsku školu
01:41
as I missed mathematics.
24
101816
1965
jer mi je nedostajala matematika.
01:45
Soon after, I found the coolest thing:
25
105019
2936
Ubrzo potom otkrila sam sjajnu stvar:
01:48
I can use mathematics to study medicine.
26
108692
2763
Mogu koristiti matematiku za studij medicine.
01:53
Since then, I've been developing algorithms to analyze biological data.
27
113026
5213
Od tada razvijam algoritme za analizu bioloških podataka.
01:59
So, it sounded easy:
28
119092
2283
Dakle, zvučalo je jednostavno:
02:01
let's collect data from all the metabolites in our body,
29
121399
3601
prikupimo podatke o svim metabolitima u našem tijelu,
02:05
develop mathematical models to describe how they are changed in a disease
30
125024
5128
razvijmo matematičke modele za opisivanje kako se mijenjaju u bolesti
02:10
and intervene in those changes to treat them.
31
130176
2988
i intervenirajmo u te promjene kako bismo ih liječili.
02:14
Then I realized why no one has done this before:
32
134488
3472
Tada sam shvatila zašto to nitko nije učinio prije:
02:19
it's extremely difficult.
33
139230
1687
to je iznimno teško.
02:20
(Laughter)
34
140941
1087
(Smijeh)
02:22
There are many metabolites in our body.
35
142052
2412
Postoje mnogi metaboliti u našem tijelu.
02:24
Each one is different from the other one.
36
144783
2500
Svaki od njih različit je od onog drugog.
02:27
For some metabolites, we can measure their molecular mass
37
147307
3728
Nekim metabolitima možemo mjeriti molekularnu masu
02:31
using mass spectrometry instruments.
38
151059
2593
instrumentima za spektrometriju mase.
02:33
But because there could be, like, 10 molecules with the exact same mass,
39
153676
4393
No kako bi moglo biti, recimo, 10 molekula s istom masom,
02:38
we don't know exactly what they are,
40
158093
1807
ne znamo točno koje su,
02:39
and if you want to clearly identify all of them,
41
159924
2774
pa ako ih želite sve jasno identificirati,
02:42
you have to do more experiments, which could take decades
42
162722
3104
treba raditi još eksperimenata, što bi moglo trajati desetljećima
02:45
and billions of dollars.
43
165850
1714
i stajati milijarde dolara.
02:48
So we developed an artificial intelligence, or AI, platform, to do that.
44
168207
5563
Tako smo razvili umjetnu inteligenciju, ili AI, kao platformu koja će to učiniti.
02:53
We leveraged the growth of biological data
45
173794
2844
Iskoristili smo rast bioloških podataka
02:56
and built a database of any existing information about metabolites
46
176662
4424
i izgradili bazu podataka svih postojećih informacija o metabolitima
03:01
and their interactions with other molecules.
47
181110
3128
i interakcija njih s drugim molekulama.
03:04
We combined all this data as a meganetwork.
48
184262
3424
Povezali smo sve te podatke u megamrežu.
03:07
Then, from tissues or blood of patients,
49
187710
3396
Zatim iz tkiva ili krvi bolesnika
03:11
we measure masses of metabolites
50
191130
2751
mjerimo mase metabolita
03:13
and find the masses that are changed in a disease.
51
193905
3259
i tražimo one koje se mijenjaju u bolesti.
03:17
But, as I mentioned earlier, we don't know exactly what they are.
52
197188
3190
Ali, kao što sam spomenula ranije, ne znamo točno koji su.
03:20
A molecular mass of 180 could be either the glucose, galactose or fructose.
53
200402
5135
Molekulska masa 180 može biti glukoza, galaktoza ili fruktoza.
03:25
They all have the exact same mass
54
205561
2019
Sve one imaju iste mase
03:27
but different functions in our body.
55
207604
2087
ali različite funkcije u našem tijelu.
03:29
Our AI algorithm considered all these ambiguities.
56
209715
3587
Naš AI algoritam uzima u obzir sve te nedorečenosti.
03:33
It then mined that meganetwork
57
213326
2736
Zatim pretražuje tu megamrežu
03:36
to find how those metabolic masses are connected to each other
58
216086
4353
da vidi kako su te metaboličke mase međusobno povezane
03:40
that result in disease.
59
220463
1958
kad rezultiraju bolešću.
03:42
And because of the way they are connected,
60
222445
2238
I po načinu na koji su povezani,
03:44
then we are able to infer what each metabolite mass is,
61
224707
4323
onda možemo zaključiti što je svaka metabolička masa,
03:49
like that 180 could be glucose here,
62
229054
2924
kao, ovdje bi 180 mogla biti glukoza,
03:52
and, more importantly, to discover
63
232002
2551
i, što je još važnije, otkriti
03:54
how changes in glucose and other metabolites
64
234577
3367
kako promjene u glukozi i drugim metabolitima
03:57
lead to a disease.
65
237968
1505
dovode do bolesti.
03:59
This novel understanding of disease mechanisms
66
239497
2995
To novo razumijevanje mehanizama bolesti
04:02
then enable us to discover effective therapeutics to target that.
67
242516
4492
omogućuje nam zatim otkrivanje učinkovitih ciljanih terapija.
04:07
So we formed a start-up company to bring this technology to the market
68
247601
3845
Stoga smo osnovali start-up tvrtku kako bismo tu tehnologiju stavili na tržište
04:11
and impact people's lives.
69
251470
1805
i poboljšali živote ljudi.
04:13
Now my team and I at ReviveMed are working to discover
70
253722
3545
Sada moj tim i ja u ReviveMed radimo na otkrivanju
04:17
therapeutics for major diseases that metabolites are key drivers for,
71
257291
5105
terapija za glavne bolesti kojima su ključni pokretači metaboliti,
04:22
like fatty liver disease,
72
262420
1897
poput bolesti masne jetre,
04:24
because it is caused by accumulation of fats,
73
264341
2924
jer je uzrokovana nakupljanjem masti,
04:27
which are types of metabolites in the liver.
74
267289
2473
koje su vrste metabolita u jetri.
04:29
As I mentioned earlier, it's a huge epidemic with no treatment.
75
269786
3940
Kao što sam spomenula ranije, to je ogromna epidemija bez lijeka.
04:33
And fatty liver disease is just one example.
76
273750
2724
A bolest masne jetre je samo jedan primjer.
04:36
Moving forward, we are going to tackle hundreds of other diseases
77
276498
4178
Ubuduće ćemo se boriti sa stotinama drugih bolesti
04:40
with no treatment.
78
280700
1493
za koje nema lijeka.
04:42
And by collecting more and more data about metabolites
79
282217
4554
Prikupljanjem sve više podataka o metabolitima
04:46
and understanding how changes in metabolites
80
286795
3544
i razumijevanjem kako promjene metabolita
04:50
leads to developing diseases,
81
290363
2402
dovode do razvoja bolesti,
04:52
our algorithms will get smarter and smarter
82
292789
3489
naši algoritmi će postajati sve pametniji
04:56
to discover the right therapeutics for the right patients.
83
296302
4196
u otkrivanju pravih terapija za pravog pacijenta.
05:00
And we will get closer to reach our vision
84
300522
3770
Približit ćemo se ostvarenju naše vizije:
05:04
of saving lives with every line of code.
85
304316
3863
spašavanja života sa svakim retkom koda.
05:08
Thank you.
86
308203

Hvala vam.
