CellWorks, one of the fast growing companies in India, was recently
awarded the Emerging Company of the Year 2011 award for outstanding
contribution to the field of bioinformatics and systems biology sector
by the Government of Karnataka. Spearheading the research division of
this organization is Dr Shireen Vali, who co-founded the company with
her husband, Mr Tahir Abbasi, and Mr Pradeep Fernandes.
Following her graduation from Osmania University, Dr Vali went to the
US where she carried out preliminary research work in the City of Hope
National Medical Center, California. Dr Vali then received her PhD in
neurobiology from the University of California and since then she has
been actively involved in elucidating the pathways involved in various
diseases. Her post-doctoral work at Stanford University focused on
cystic fibrosis following which she worked in the field of cancer
biomarkers.
Dr Vali came back to India in 2003 and joined the Institute of
Bioinformatics and Applied Biotechnology (IBAB) as a faculty member. It
was here that the idea for CellWorks was incubated.
Dr Vali’s research interests mirror those of the organization’s, which
consist of elucidating pathways involved in complex diseases and using
systems biology to create disease models that can then be used to
design targeted drug therapies akin to personalized medicine.
Dr Vali has worked towards setting up co-culture systems of various
disorders, such as rheumatoid arthritis, cancer and wound healing
consisting of systems involving over eight cell types, including
osteolclasts, T cells, endothelial cells, epithelial cells macrophages
and dendritic cells.
On the approach they have adopted in discovering drug therapies, Dr
Vali says, “We carry out retrospective validations with data that is
existing but has not been used to build or align the systems and also,
prospective validations with global collaborators, who have tested
their predictions.”
Focus on rheumatoid arthritis has yielded two combination drugs, one of
which has completed animal trials and the other is entering the
preclinical stage. Cancer, a multiphenotypic disorder presents a major
challenge, one that is tackled in a unique manner, explains Dr Vali.
“We have enabled the co-culture systems to incorporate all the
components such as angiogenesis and metastasis by using the cellular
models in the tumor system. Focusing on specific cancer types, which
are epithelial in origin, we profile the tumor based on the key
mutations and these mutations are overlaid on the system to generate a
dynamic tumor state, which matches in terms of mutations with those
found in certain cell lines. Based on the different types of mutations,
the tumor has differential sensitivity to different drugs and using
this information we are able to customize the drug profile for a
patient or a group of patients,” says Dr Vali.
Collaborations with different institutions, such as Astra Zeneca, City
of Hope San Diego, University of Cancer UK and National Institute of
Singapore, have resulted in many publications in reputed journals. One
study carried out in collaboration with National Institute of Mental
Health and Neuro Sciences, Bangalore studied the effect of curcumin for
treatment of Parkinson’s using a virtual dopaminergic neuron consisting
of astrocytes and microglia, which helped ascertain the effects of
curcumin. This system gave many insights on how to correlate the effect
of curcumin.
Talking about the road ahead, she says, “In the next five years, I
would like some of our drug combinations to be in the later phases of
clinical trials. It is an aggressive strategy, but one which will help
us get therapies out in the market as soon as possible to help the
people suffering from these diseases.”
