Health and food: Genomics science towards
the development of new drugs and stress
tolerant plants
HEALTH
The dilemma of pharmaceutic industry in
developing new drugs
Industry R&D return on investment (ROI) as calculated in
Deloitte's innovation report 2015
Dickson & Gagnon (2014) Nature Reviews Drug Discovery
The costs of developing new drugs are estimated at USD 2.6
billion, more than twice the value in 2013
DiMasi et al., (2016) Journal of Health Economics 47 (2016) 20–33
Lack of efficacy
• 2007-2010
- Phase II - 51%
- Phase III - 66%
• 2011-2012
- Phase II - 59%
- Phase III - 52%
• 2013-2015
- Phase II - 48%
- Phase III - 55%
• These failures are expensive
• These failures are duplicated in
multiple companies
• Biology is poorly understood
• Target was not properly validated
The increase in costs is because most drug candidates fail
for lack of efficacy
Prinz et al. (2011) Nature Reviews Drug Discovery
Work at Bayer found that out of 67 published target-validation
studies, only 20-25% were reproducible
• Urgent need for good quality tools
to help enable reproducible science
Most studies for target validation is not reproducible
FOOD
The drought and high temperature stress
imposed by climate changes constitute a
significant threat to food production
Global food consumption and its sources
Source: A world of insecurity (2017) Nature, 544: 57
• The main sources of energy for human are carbohydrates from cereals, fats from
leguminous plants and animal, milk and eggs, fruits and vegetables, meat and fish.
• Carbohydrates, fats, milk, eggs and meat, that together account for 80-90% of the energy
consumed by human, are directly or indirectly derived from 5 crops: rice, maize, soybean,
wheat, and sugarcane.
• To meet the energy needs of a population estimated at 9 billion by 2050, it will be
necessary to increase the productivity of these five crops by 50-60%.
An extreme drought (and heat) in the 2012/13 crop imposed a lost of 40 Million Tons of maize.
This is equivalent to the average of Brazilian production in the period 2005-2010 (49 Mt).
Impact of extreme climatic events for maize production in
the USA
Genome science will have a real impact on all our lives
-- and even more, on the lives of our children. It will
revolutionize the diagnosis, prevention and treatment of
most, if not all, human diseases
…In fact, it is now conceivable that our children's
children will know the term cancer only as a
constellation of stars.
…Researchers in a few years will have trouble
imagining how we studied human biology without the
genome sequence in front of us.
The -omics revolution
June 26, 2000
Would the -omics revolution help health and food?
How can -omics promote …
• Finding disease-linked gene variants
• Understanding mechanisms of disease
• New drug targets
• Genotyping – tailoring cures to patients
• Molecular diagnosis
• Opening up unexplored areas of human biology
• Genome editing

• The GSC was founded in late 2003 with funding from the Wellcome
Trust and GlaxoSmithKline to establish a Public Open Innovation
Consortium
• It commenced operations in June 2004 at the Universities of Oxford and
Toronto and has since expanded its PPP network
• In September 2017 the SGC network comprises + 280-researchers in
Oxford, Toronto, Stockholm, Campinas, Chapel Hill and Frankfurt
• The GSC is currently funded by large pharmaceutical companies and
governamental agencies
• Open Science Policy: Promptly placing results, reagents and know-
how in the public domain. SGC scientists dont file patents
Secrecy imposed by early stage IP protection delay the
process o Drug Discovery
The Structural Genomics Consotium (SGC) open innovation model to accelerate DDD
~20 kinase probes
SGC genome-scale work on Human Kinases
Kinases are potential targets for DD as it is involved in almost all cellular metabolism
and is linked to diseases like cancer, pain, inflammation, etc
Currently there are 42 Kinase targeted medicines in the market to treat these diseases

16S and ITs massive amplicons sequencing revealed ~22K
bacteria and 10K fungi groups inhabiting the sugarcane
• A significant proportion of the microbial diversity is shared among samples
• But plant organs select their most preferable microbes probably through
functional enrichment
• Soil serves as reservoir for the assemblage of plant organ microbiota

Microbiome mapping revealed that the synthetic community made with highly abundant
sugarcane bacteria inoculated in maize plants displaced the natural maize microbiota,
efficiently colonize the plant organs, and stimulate the root system and plant growth
Highly abundant bacterial are robust colonizers
Robust colonizers are enriched in genes encoding specific
functions
• The complete genome
sequences of the synthetic
community revealed 26
bacteria;
• Robust colonizers share a set
of enriched functions;
• Some of the specific
functions are absent in non-
robust colonizers;
• Genes related to
carbohydrate metabolism,
energy production and
secondary metabolites are
among the top categories
that are enriched in the
robust colonizers;
Velloziaceae species growing in exposed rocks and shallow patches of soil in Brazilian campos
rupestres (rupestrian grasslands) (A,B,C). Example of a desiccated Vellozia nivea (ressurection) after
four months without rain and the same plant six days after rain, respectively (D). Vellozia intermedia
(ever green) after four months without rain and the same plant six days after rain, respectively (E-F).
