Personal Statement


The focus of my Lab is to unravel the cellular and molecular mechanisms of selected natural-based
biomolecules against cancer. Through utilizing various cellular & molecular, nanoparticles, bioinformatics and
metabolomics techniques we investigated a variety of biomolecules and introduced them as potential drug
targets. In an early study, we reported saffron’s potent anti-cancer effect against liver cancer and showed that
saffron’s anticancer effect was mediated by its anti-proliferative, pro-apoptotic and anti-inflammatory actions
(Amin et al., Hepatology, 2011, 54(3): 857-867). We then investigated the anticancer activities of saffron’s bioactive
molecules (crocin and saffron) against both liver and colorectal cancers where we showed that autophagy
facilitated the crocin-mediated effects against colorectal cancer. Recently, we developed nanoparticles to
enhance the pharmacological effects of crocin against liver cancer (Awarded PhD Thesis; El-Kharrag et al.,
International Journal of Oncology 50: 212-222). We have also just completed an in vivo experiment to investigate
the therapeutic potential of saffron’s biomolecules and are currently analyzing those very exciting new results
(Two ongoing MSc Theses).
Most recently, we provided in vitro evidence that safranal exerts its anticancer effect through interfering with
DNA replication and inhibiting DNA repair machinery resulting in an increased DNA damage. Inhibited protein
expression of main contributors of DNA double-stand-break repair mechanism such as TDP1, HDAC1 and
HDAC2 clearly supported that notion. Safranal also induced the phosphorylation of histone-H3 and the cleavage
of PARP resulting in cell cycle arrest. Apoptosis was triggered as safranal activated initiator caspases of both
intrinsic and extrinsic pathways. Extended safranal-induced ER stress may elucidate the activation of both
caspase-8 and -9, which are also indicators of ER stress-mediated apoptosis. Expectedly, caspase-3 and -7, the
downstream targets of the initiators, were activated upon safranal treatment. These findings were interestingly
consistent with systems analysis where unfolded protein response was shown to be among the top GO terms of
up-regulated genes in response to safranal treatment for 12 and 24 h. Our recently reported results suggest a
novel mechanism of safranal-mediated inhibition of liver cancer both in vitro and in vivo (both in murine and
zebrafish models) (in publication).
First and in collaboration with computational biologists and bioinformaticians, we are now utilizing
metabolomics to understand how safranal affects different pathways (namely, apoptosis and inflammation) in
hepatocellular carcinoma (HCC). Toward that goal, we are set to define gene expression profile of HepG2 along
with other liver cell lines treated with this bioactive molecule. This study will take advantage of RNASeq technique
to define gene expression profiles of HepG2 cells with or without safranal treatment and to identify metabolic
pathways affected by safranal through metabolic modeling integrated with RNASeq expression data and
metabolic phenotype array profiles. In addition, transcriptome analysis of safranal-treated HepG2 cells is
currently underway using Illumina HiSeq2000 and high performance computing clusters. Following transcriptome
sequencing, obtained reads will be mapped to a human reference sequence and expression of genes will be
determined by calculating RPKM values for each gene. The NOISeq software will group genes that are
upregulated, downregulated, or unaffected for further analyses. We will then use the manually curated
knowledge-based Ingenuity Pathway Analysis (IPA) designations to introduce functional relevance to up- and
down-regulated genes after safranal treatment for 12 and 24 h. Among the IPA preliminarily generated (Figure
4), top enriched networks were liver hyperplasia/hyper-proliferation, hepatocellular carcinoma, liver proliferation,
liver necrosis/cell death and liver regeneration. Those networks indicated the inhibition of HCC at both 12 and
24 h after safranal treatments (Ongoing MSc Thesis).
As current HCC therapies have made little impact on survival, alternative strategies are desperately needed.
Two major problems with current cancer therapies have been identified. Firstly, chemotherapeutic agents do not
eradicate the cancer stem cells, which are the only cells able to recapitulate the tumor and are responsible for
forming distant metastases. Secondly, cancer cells recruit peritumoral stromal cells that induce interactions that
benefit the cancer and reduce penetration of therapeutic drugs. Thus, in other major project, we are targeting
the cancer stem cells (CSC) and the stroma by chitosan nanoparticles carrying a payload of metformin and the
smoothened inhibitor vismodegic, both of which have been shown to eradicate CSC. These nanoparticles will
target CSCs by incorporating monoclonal antibodies to CSCs’ marker EpCAM and will carry rhodamine 123 dye
for tracking the nanoparticles after injection. In addition, pegylated hyaluronidase will be employed to target and
disrupt the peritumoral storma and prevent its reformation. The nanoparticles will be optimized and their
effectiveness of eradicating CSCs will be evaluated both in vitro and in vivo. Their effectiveness in vivo will be
assessed both alone and in combination with HCC conventional therapies; mainly sorafenib. The overall goal is
to provide a more effective treatment for patients with HCC.
Despite the need to establish reliable and physiologically relevant in vitro assays that relates better to the in
vivo environment, the vast majority of studies using cancer cell lines remain to be performed in traditional
monolayer cultures. The development of culture system that fully mirrors cancer and its diverse cellular
microenvironment is lagging and needs to be further developed. Recent studies have shown that the tumor
microenvironment plays a critical role in modulating the process of liver hepatocarcinogenesis, fibrosis, epithelialmesenchyme
transition, tumor invasion and metastasis. In another ongoing project in my lab, we have set up a
tumor environment of HCC using three-dimensional culture to evaluate the effects of microenvironment
interactions through analyzing the transcriptome and proteome of both liver cancer cells and their stromal
counterparts (Defended MSc Thesis).
