Lung cancer has
become the one of the prominent threats to global healthcare, with death rate
of one out of four deaths in both men and women. It is among one of cause of cancer related deaths all over
the world 1. Golbally lung cancer accounts for
about 13 % of
new cancer cases and 19 % fatality . In India, lung cancer accounts for
6.9 % of new cases and 9.3% deaths in both sexes, it is the commonest
cancer and cause of cancer related mortality in men, and second most in women after breast and
ovarian carcinoma 2. Depending on tumour size and stages of
lung cancer several therapeutic regimens are available to treat lung cancer.
Yet conventional treatments like chemotherapy and radiation therapy are
associated with several adverse effects on the human system. Even though of the progress in development of several anticancer drugs, chemoresistance
is still major hindrance that results in
Multiple factors are involved in development of chemoresistance such as
inactivation of chemotherapy drug, alteration in tumor suppressor gene, anti
and pro apoptotic proteins. Understanding the moleculer role of tumor encoded
gene in development of drug resistance has great significance in development of
novel therapeutic target and also improve diagnosis4.
transglutaminase 2 (TG2) is one of
ubiquitously expressed protein among 7 members of Tissue TG family. It is known
to be involved in tumor metastasis 5. It is distributed among
major cell types and tissues and plays a significant role in several biological
processes. It take part in post-translation modification transamidase activity it is involved in
GTPase, ATPase, protein kinase, protein disulfide, and isomerase activity 6.
TG2 levels leads to different
pathological disorders such as Alzheimer’s, Parkinson’s disease, multiple
sclerosis, celiac along with tumour
development while Over expression of TG2is associated with malignant effects
leading to tumorigenesis, invasion, cell differentiation, and failure in apoptosis
7.As a consequence, TG2 is known to have a significant impact in lung
carcinoma, especially towards n
on-small cell lung carcinoma 8.
Targeting TG2 protein may be valuable in identifying potential inhibitors
against lung cancer. Numerous natural compounds have been reported to have many
biological activities as antibacterial, antiviral and anti-cancer 9. Natural
products and their derivatives mimic over 50% of all the products that are
being used. In the present study an attempt is made in silico investigation of natural inhibitors against TG2 from
plant origin. The hit compounds obtained in this study could play an important
role in designing personalized therapy against lung cancer patients.
