University, World’s largest
Genome Research Center)

Welcome Speech
by Founder of MGRC, Dr Robert Herkes
-
introduction of building blocks of genetics
which is synonym to the ‘lego’ building blocks
-
the elements that build up our bodies:
Hydrogen, Carbon, Oxygen, Nitrogen, Sulphur and
Phosphate( H,C,O,N,S,P)
-
H,C,O made up the glucose, H,C,O,N made up
the amino acids, H,C,O,N,S, P made up the nucleic
acid
-
Human genome is 4 or 5 times more than the
bacteria
-
Bioengineering is the study of bio mechanism
in cells through manipulation
Introduction of
Bioengineering by CEO of MGRC, Dr Iskandar Mohd Isa
-
predicted that by 2010, science will be
converted into business
-
2011- 2015, expedite & intensify technology
development & licensing to share to the world.
-
Scientific capability of Malaysia: at least
25 biotechnology companies are to generate 80,000
job opportunities with an estimated profit of RM9
billion which contributes 4% of the GDP
-
Predicted that many biotechnology companies
are able to achieve success earlier than 2015.
-
Example: Bio Nexus Co. has announced its
talks with Hoffman Recouge to work on cancer
treatment, where the phase 2 clinical trial will be
in Malaysia with its center in Cuba, U.S.A
-
There is much evidence that Malaysia is ready
for bigger biotech achievements although many
Malaysians are still in doubt of our abilities.
-
As Malaysians, we are able to achieve the
target and we must believe we are able to work &
realize it. Students are building blocks of it.
Deciphering the
Leukemia Genome Using Next Generation DNA Seuencing
Technologies, Dr Elaine Mardis, Washington
University, U.S.A
-
The Genome Research Center of Washington
University, in St Louise, Missouri, U.S.A
established in 1993
-
Through the use of the biotechnology, the
cost of running the research in the university has
decreased from 2001-2005.
-
The De novo genome sequences is to study
many organisms, especially cancer. The center
initiated project also include study on parasites
-
The study of Human & mouse genomes has been
completed but continues to close gaps & refine
annotations. Besides that they are also studies on
the Y chromosome, chimp, chicken & zebra genomes,
maize & microbial genomes
-
On physical mapping, they have done map
construction, genome assembly, gap closure &
illuminia genotyping
-
Under technology development, they have
revolutionary DNA sequencing & medical sequencing
-
Platform for next generation DNA sequencing
technology included: 454, Solexa, and SoliD which
are faster & generate more sequencing compared to
previous technology like 3730
-
454 sample preparation involve: random
fragmentationà
adaptor ligation
àsingle
stranded adaptor ligator library
à anneal sDNA
& oligocoated beads
àemPCR for
donal amplification
à enrich
count( each bead is coated with many sequencing
reaction)
-
454 FLX evaluation is more than 100Mb data
in7 hrs; read 250 bp, reading capability is 3kb
separation
-
Next generation sequencing focused on
diagnostic/ prohostic assays for clinic & may help
identify targeted therapist for treatment
-
There is a 1,000 genomes project (www.1000genomes.org/)
where the imputed genomes will be publicly available
at the given web site as will all the primary data
-
Dr Elaine presented her study in PCR directed
sequences in cancer which focused on whole genome
tumor resequence of next generation sequencing, data
analysis strategy etc.
-
Steps involved: chromosomes
à sequencing
à expression
arrays of RNA expression, clinical data for
correlation
à functions
in biology, targets & assays
-
Tumor sequencing project (TSP) involve 620
genes of interest, 200 lung ad neon carcinoma
-
Whole genome work with SNP,CNV & HOP
-
Found that pure KDC (PRKDC) is highly
mutated, collected from 2.4 mutations/samples from
non-smokers (have never smoked)
-
The hypothesis driven on kinome, phosphatone
& data driver use genomic platforms to identify loci
with recurrent somatic alteration
-
Acute myelogenous leukemia is AML directed
sequences of FLT3 & NPM1 mutations known for whole
genome sequence
-
SNP array data can be used to acquire
sequences for hundreds of thousands of position
across the genome & improve on the error rate
-
CDNA sequence is capable of providing rapid
coverage of the interpreted genome & add information
about genes expressed in the tumor
-
Next generation sequencing of DNA & RNA is
for alignment on mutation detection, storage,
annotation, analysis & to determine somatic status
-
The new up-coming project is on txome
sequencing
-
Dr Elaine concluded her presentation by
stressing that the world & Malaysia need more
bioinformatics students
We were very lucky
to be the only school invited to the talk for free.
Many late comers had to sit on the walk way since
the hall was full & no free seat. Even though most
of us didn’t really understand the talk fully, we
were exposed to the latest research & technology.Who
knows, one day, one of us might be able to achieve
this level of tertiary learning. We took our lunch
before we left the school for the talk. After the
high- powered talk, we were very exhausted & were
lucky to be treated to tea before we left for
school.
