About
\
A human genetics and stem cells research group was established to unravel the genetic causes of the monogenetic disorders that are prevalent in the local population. It also forms a platform for researchers to unravel the molecular processes that govern stem cell differentiation.The group members aim to adopt innovative approaches to enrich our understanding of the genetic component of monogenetic disorders and strive to improve differentiation protocols for the differentiation of human mesenchymal and dental pulp stem cells into neural and adipocyte lineages.
Background
A human genetics and stem cells research group was established to unravel the genetic causes of the monogenetic disorders that are prevalent in the local population. It also forms a platform for researchers to unravel the molecular processes that govern stem cell differentiation. The group members aim to adopt innovative approaches to enrich our understanding of the genetic component of monogenetic disorders and strive to improve differentiation protocols for the differentiation of human mesenchymal and dental pulp stem cells into neural and adipocyte lineages.
Goals & Objectives
The mission statement of the research group is to identify and study the genetic causes of monogenic disorders in the UAE population and to conduct research on the differentiation of mesenchymal and dental pulp stem cells into Adipocytes and neural lineages. The group aims to translate some of its research findings in therapeutic manners for the wellbeing of the patients.\ \ The group has two major branches: human genetics and stem cells\ \ For human genetics, we will identify the disease-causing gene(s) and mutation(s) underlying several autosomal recessive disorders (ARDs) in consanguineous families from UAE. Our specific objectives are: \ \
- Ascertain and recruit novel cases underlying ARDs from UAE
- Perform genome-wide scan using SNP arrays to identify the disease-causing loci based on homozygosity mapping
- Perform whole-exome sequencing in some of the affected individuals of each family
- Select potential disease-causing mutations within the homozygous regions using bioinformatics tools
- Carry out functional assays to validate or rule out the pathogenicity of the identified variations
For stem cells research we have the following objectives:
- To set up the human dental pulp and mesenchymal stem cells platform for research by isolating, growing, characterizing, and cryopreserving the mesenchymal stem cells isolated from human teeth. The group is using Telomerase Transformed Immortalized Mesenchymal Stromal cells (iMSC3) as a model for mesenchymal stem cells
- To evaluate the neural differentiation capability of the different subsets of the human dental pulp and mesenchymal stem cells under specific growth factor combinations
- To find key microRNAs and key genes involved in the differentiation of human dental pulp and mesenchymal stem cells into neural lineage by performing the whole RNA sequencing by next-generation sequencing
- To enhance further the differentiation of the human dental pulp stem cells and mesenchymal stem cells into neural lineages by transfecting the stem cells with specific microRNAs that are differentially and uniquely expressed
- To derive a better and efficient 3-D model for the dental pulp and mesenchymal stem cells.
- To unravel the molecular mechanisms in the differentiation of dental pulp and mesenchymal stem cells into adipocytes, in vitro model of obesity.

Current Projects & Future Directions
- Analyze the influence of exposure to common environmental toxins on normal mammary, colonic or skin epithelial cells and isogenic breast or colon cancer cells harboring common molecular alterations.
- Analyze the role of epithelial to mesenchymal transition in colon and breast carcinogenesis and identify novel mediators of this phenomenon.
- Role of p53 & microRNA in apoptosis, epithelial to mesenchymal transition and chemo-resistance.
- Carcinogenic mechanisms and predisposition to familial and Eastern subsets of colon cancer. This involves international collaboration with Finland and Egypt.
It is widely acknowledged that our environment is becoming increasingly contaminated with man-made chemicals. Mammals, as well as lower organisms, are vulnerable to exposure to these agents through a variety of different sources and routes and there are concerns that they may be having a detrimental effect on ecological and population health.
Endocrine disruptors (EDs) have been described as exogenous agents that interfere with the production, release, transport, metabolism, binding, action or elimination of the natural ligands responsible for maintaining homeostasis and regulating body development. Many different EDs are present in the various compartments of the environment (air, water and land) and in foods (of plant and animal origin). They may originate from food packaging, combustion products, plant health treatments, detergents and the chemical industry in general.
Children obesity is a colossal concern as it predisposes to various health problems, which are linked later with adult morbidity and mortality. Previously, the child obesity prevention programs were mainly focusing on promoting the physical exercise and cutting down calories, while it has been proposed recently that endocrine disrupters such as Phthalate and BPA have a significant role in the drastic increment of child obesity incidence. Various studies have proved the relation between the levels of urinary phthalates and BPAs to children obesity; however, more validation is required by relating the active forms levels in the serum with the child obesity.
