Abstract:
Heat shock proteins (Hsps) forms the most ancient
defense system of living cells. Having chaperoning
functions, Hsps are highly conserved, abundant and
ubiquitously expressed in all cells and tissues. Despite
technological advancements and enormous input on target
based drug designing to combat cancer, anticancer
treatment is still being challenged, which is due to,
tumor being a polygenic disease. Comparing with
conventional biomarker targeting, tumor specific
functions of Hsps identify them as possible markers to
target cancer. Therefore in the recent years
chemotherapeutic intervention of Hsps has emerged as
novel anticancer treatment. Induction of cytostasis or
apoptosis are the two major mechanism of action from
anticancer drugs, however, understanding the nature and
interplay of cellular factors that help in regulating
the intra-cellular functions in an orchestrated manner
can guide through target based therapies. Increasing
cancer incidences with civilization and age, furthermore
suggest a need for better understanding of cellular
environment during any chemotherapeutic intervention.
Cell killing through single drug or combinatorial
treatments though proposed to be the current concept of
anticancer treatment, cancer immunity and bystander-cell
safety opposes the hypothesis. The careful understanding
of oncogensis and tumor suppression suggests activation
of alternative cellular mechanisms to combat cancer
instead of killing, one such mechanism is forced
cellular senescence of tumor cells. I would like to
bring forth the current knowledge on Hsps and their
central cellular roles and discuss advantages and
disadvantages of Hsp targeting in anticancer treatments.
Also demonstrate the progressive outlook of Hsp
targeting from our ongoing studies and propose Hsp
targeting as tumor suppressor mechanism.
