so thanks to the TEDx value for inviting me to speak with you today about
me to speak with you today about
me to speak with you today about something I’m very passionate about so
something I’m very passionate about so
something I’m very passionate about so I’m a brain surgeon a researcher and a
I’m a brain surgeon a researcher and a
I’m a brain surgeon a researcher and a mom and the two most common statements I
mom and the two most common statements I
mom and the two most common statements I get from people when they hear this
get from people when they hear this
get from people when they hear this about me is one you don’t really look
about me is one you don’t really look
about me is one you don’t really look like a neurosurgeon I’m not really
like a neurosurgeon I’m not really
like a neurosurgeon I’m not really certain what a neurosurgeons supposed to
certain what a neurosurgeons supposed to
certain what a neurosurgeons supposed to look like but if I’m knocking down
look like but if I’m knocking down
look like but if I’m knocking down stereotypes I think that’s a good thing
stereotypes I think that’s a good thing
stereotypes I think that’s a good thing the other comment I get is how do you
the other comment I get is how do you
the other comment I get is how do you have four kids and still be a
have four kids and still be a
have four kids and still be a neurosurgeon and I think this is what
neurosurgeon and I think this is what
neurosurgeon and I think this is what I’m passionate about when I was a
I’m passionate about when I was a
I’m passionate about when I was a medical student at UBC my Dean actually
medical student at UBC my Dean actually
medical student at UBC my Dean actually told me that women did not go into
told me that women did not go into
told me that women did not go into neurosurgery that wasn’t a career for
neurosurgery that wasn’t a career for
neurosurgery that wasn’t a career for people that wanted to have families and
people that wanted to have families and
people that wanted to have families and so I stand here today for anybody who is
so I stand here today for anybody who is
so I stand here today for anybody who is interested in a career where they think
interested in a career where they think
interested in a career where they think that they cannot have a family and tell
that they cannot have a family and tell
that they cannot have a family and tell you I have four kids two of them are who
you I have four kids two of them are who
you I have four kids two of them are who are in the audience and I think they
are in the audience and I think they
are in the audience and I think they would agree they enjoy having a mother
would agree they enjoy having a mother
would agree they enjoy having a mother who’s a neurosurgeon so I’m going to
who’s a neurosurgeon so I’m going to
who’s a neurosurgeon so I’m going to talk about what I do what some how I
talk about what I do what some how I
talk about what I do what some how I deal with uncertainty and something that
deal with uncertainty and something that
deal with uncertainty and something that I’m very passionate about and I think
I’m very passionate about and I think
I’m very passionate about and I think passion is something you’ve heard a lot
passion is something you’ve heard a lot
passion is something you’ve heard a lot today
today
today uncertainty drives innovation in brain
uncertainty drives innovation in brain
uncertainty drives innovation in brain tumors so these are words that I say
tumors so these are words that I say
tumors so these are words that I say every week it doesn’t make me very
every week it doesn’t make me very
every week it doesn’t make me very popular you have a malignant brain tumor
popular you have a malignant brain tumor
popular you have a malignant brain tumor and I say this much too often and so
and I say this much too often and so
and I say this much too often and so when I’m talking about a malignant brain
when I’m talking about a malignant brain
when I’m talking about a malignant brain tumor I’m talking about this
tumor I’m talking about this
tumor I’m talking about this glioblastoma multiforme II form a

white ugly thing that’s brain cancer
white ugly thing that’s brain cancer unfortunately this is the most common
unfortunately this is the most common
unfortunately this is the most common type of brain cancer in adults and it is

uniformly fatal the average life
uniformly fatal the average life expectancy is 12 to 14 months the 5-year
expectancy is 12 to 14 months the 5-year
expectancy is 12 to 14 months the 5-year survival is less than 10% so why is that
survival is less than 10% so why is that
survival is less than 10% so why is that what is it about this disease that makes
what is it about this disease that makes
what is it about this disease that makes it so fatal you know this is a CT scan
it so fatal you know this is a CT scan

so the first project I have is on RNA
so the first project I have is on RNA stress granules and if you’re sitting
stress granules and if you’re sitting

RNA stress granules and this is where
RNA stress granules and this is where serendipity kind of takes over in your
serendipity kind of takes over in your
serendipity kind of takes over in your life because another graduate student

life because another graduate student came up to me and said why are you
came up to me and said why are you
came up to me and said why are you talking about RNA stress granules that’s
talking about RNA stress granules that’s
talking about RNA stress granules that’s a developmental thing I’m working on and
a developmental thing I’m working on and
a developmental thing I’m working on and that started off a research
that started off a research
that started off a research collaboration that I still do today so
collaboration that I still do today so
collaboration that I still do today so what is a stress granule well tumor
what is a stress granule well tumor
what is a stress granule well tumor cells some of them live on earth so it’s

cells live on Mars they live in a very hostile environment there’s no oxygen
hostile environment there’s no oxygen
hostile environment there’s no oxygen there’s radiation around there’s
there’s radiation around there’s
there’s radiation around there’s chemotherapy and somehow

these cells have adapted so they can
these cells have adapted so they can survive this so they live in this
survive this so they live in this
survive this so they live in this hostile environment easily in fact these
hostile environment easily in fact these
hostile environment easily in fact these tumors are these tumor cells on Mars are
tumors are these tumor cells on Mars are
tumors are these tumor cells on Mars are the hardest to kill and so RNA stress
the hardest to kill and so RNA stress
the hardest to kill and so RNA stress granules are a way of that cell adapting
granules are a way of that cell adapting
granules are a way of that cell adapting to living to the harsh environment of
to living to the harsh environment of
to living to the harsh environment of Mars so these are what are any stress
Mars so these are what are any stress
Mars so these are what are any stress granules look like so the lid there’s
granules look like so the lid there’s
granules look like so the lid there’s for actual brain cancer cells here the
for actual brain cancer cells here the
for actual brain cancer cells here the blue stain is the nucleus and those red
blue stain is the nucleus and those red
blue stain is the nucleus and those red dots those are the RNA stress granules
dots those are the RNA stress granules
dots those are the RNA stress granules so I’ve told you what a stress granule
so I’ve told you what a stress granule
so I’ve told you what a stress granule is though it’s RNA and this is a
is though it’s RNA and this is a
is though it’s RNA and this is a metaphor I’ve taken from Steve Jobs I
metaphor I’ve taken from Steve Jobs I
metaphor I’ve taken from Steve Jobs I can’t take credit for this but if you
can’t take credit for this but if you
can’t take credit for this but if you think of DNA as the CEO so the CEO wants
think of DNA as the CEO so the CEO wants
think of DNA as the CEO so the CEO wants to direct a message to his workers the
to direct a message to his workers the
to direct a message to his workers the protein right so how is he gonna get
protein right so how is he gonna get
protein right so how is he gonna get that message as a CEO to his workers the
that message as a CEO to his workers the
that message as a CEO to his workers the protein well he makes RNA so RNA is the
protein well he makes RNA so RNA is the
protein well he makes RNA so RNA is the message that goes from the seats the
message that goes from the seats the
message that goes from the seats the middle manager it’s the message that
middle manager it’s the message that
middle manager it’s the message that goes from the DNA to the protein to tell
goes from the DNA to the protein to tell
goes from the DNA to the protein to tell them what to do and so what a stress
them what to do and so what a stress
them what to do and so what a stress granule does it it acts as kind of like
granule does it it acts as kind of like
granule does it it acts as kind of like the external audit or auditor of the
the external audit or auditor of the
the external audit or auditor of the company so if you think of these little
company so if you think of these little
company so if you think of these little dots as messages in the cell that are
dots as messages in the cell that are
dots as messages in the cell that are out to the cell to tell them what to do
out to the cell to tell them what to do
out to the cell to tell them what to do and you apply a hostile environment what
and you apply a hostile environment what
and you apply a hostile environment what the cell what this dress granule does is
the cell what this dress granule does is
the cell what this dress granule does is says ok so these blue messages they’re
says ok so these blue messages they’re
says ok so these blue messages they’re very important I want to keep them in my
very important I want to keep them in my
very important I want to keep them in my stress granule I want to save them here
stress granule I want to save them here
stress granule I want to save them here so that when I survive this stress I can
so that when I survive this stress I can
so that when I survive this stress I can make them again and I can I can
make them again and I can I can
make them again and I can I can reestablish myself these gray messages
reestablish myself these gray messages
reestablish myself these gray messages here they’re not important they’re
here they’re not important they’re
here they’re not important they’re garbage don’t want to make them gonna
garbage don’t want to make them gonna
garbage don’t want to make them gonna degrade them don’t need them and these
degrade them don’t need them and these
degrade them don’t need them and these yellow messages these messages are
yellow messages these messages are
yellow messages these messages are important now these are the message that
important now these are the message that
important now these are the message that are gonna make you survive and make you
are gonna make you survive and make you
are gonna make you survive and make you live and adapt to this a hostile
live and adapt to this a hostile
live and adapt to this a hostile environment so again the stress granules
environment so again the stress granules
environment so again the stress granules are the external audit or a deterrence
are the external audit or a deterrence
are the external audit or a deterrence company that allow the tumor cells to
company that allow the tumor cells to
company that allow the tumor cells to live in this hostile environment and so
live in this hostile environment and so
live in this hostile environment and so one of the key things my lab tries to do
one of the key things my lab tries to do
one of the key things my lab tries to do is interfere with this process so if the
is interfere with this process so if the
is interfere with this process so if the cells can’t live on Mars they can’t live
cells can’t live on Mars they can’t live
cells can’t live on Mars they can’t live and the tumor dies and so that’s a lot
and the tumor dies and so that’s a lot
and the tumor dies and so that’s a lot of the strategies that we’re trying to
of the strategies that we’re trying to
of the strategies that we’re trying to do in my laboratory
the other strategy we’ve had is in
the other strategy we’ve had is in collaboration with dr. Jeremy brown

this tiny tiny little ultrasound probe
this tiny tiny little ultrasound probe and when you applied into SMO
and when you applied into SMO
and when you applied into SMO spaces while you’re operating it uses
spaces while you’re operating it uses
spaces while you’re operating it uses ultrasonic waves to ablate a brain tumor
ultrasonic waves to ablate a brain tumor
ultrasonic waves to ablate a brain tumor deep but leave this other surrounding
deep but leave this other surrounding
deep but leave this other surrounding tissue undisturbed and so we’re testing
tissue undisturbed and so we’re testing
tissue undisturbed and so we’re testing this ultrasound probe in the awara
this ultrasound probe in the awara
this ultrasound probe in the awara and and to see whether or not we can
and and to see whether or not we can
and and to see whether or not we can ablate brain tumors with actually having
ablate brain tumors with actually having
ablate brain tumors with actually having to come without having to actually cut
to come without having to actually cut
to come without having to actually cut into the brain and so these are just two
into the brain and so these are just two
into the brain and so these are just two projects that are going on in my
projects that are going on in my
projects that are going on in my laboratory but in the research worldwide

viruses using electromagnetic waves all an ability to try to deal with this
an ability to try to deal with this
an ability to try to deal with this devastating tumor but ultimately I’d

like to acknowledge my patients and
like to acknowledge my patients and their families because they’re the ones
their families because they’re the ones
their families because they’re the ones that gave me the drive and the courage
