Gastroenterology: Gastrointestinal diseases<br />
have increased in recent years. Work stress,<br />
alcohol, non-steroidal anti-inflammatory drugs<br />
(NSAIDS) strong tea or c<strong>of</strong>fees have contributed<br />
to the pathology. Our research is based on<br />
gastrointestinal secretion <strong>and</strong> the mechanism<br />
<strong>of</strong> action <strong>of</strong> PPIs <strong>and</strong> other acid inhibitors on acid<br />
secretion. In the early years, Histamine H2-<br />
receptor antagonist, Sucralfate <strong>and</strong> Muscarinic<br />
receptor antagonists were used more <strong>of</strong>ten.<br />
But with the introduction <strong>of</strong> the proton pump<br />
inhibitors (PPIs) their use has declined owing<br />
to the potent anti-secretory <strong>and</strong> anti-ulcer<br />
activity <strong>of</strong> the PPIs. Recently we published the<br />
work on new proton pump inhibitor,<br />
esomeprazole, Astra-Zeneca (accepted for<br />
publication [2008]). At present we are studying<br />
the interactions <strong>of</strong> aspirin in combination with<br />
ibupr<strong>of</strong>en on gastric acid <strong>and</strong> ulcer formation in<br />
the rat in vivo <strong>and</strong> in vitro (manuscript in<br />
preparation). In the near future we are planning<br />
to study the effect <strong>of</strong> stress on the mucosa <strong>of</strong> FSL<br />
<strong>and</strong> FRL rats <strong>and</strong> the healing rate <strong>of</strong> alcohol-<strong>and</strong><br />
indomethacin-induced ulcers in the same rats.<br />
Teratology: Epilepsy affects approximately 1% <strong>of</strong><br />
the world’s population <strong>and</strong> it is the second most<br />
common neurologic disorder after stroke. It is a<br />
heterogeneous symptom complex a chronic<br />
disorder characterized by chronic seizures.<br />
Approximately 0.5% <strong>of</strong> all pregnancies occur in<br />
women with epilepsy. It is known that epileptic<br />
women demonstrate a higher liability to obstetric<br />
complication than non-epileptic females <strong>and</strong><br />
congenital malformations are more common in<br />
their <strong>of</strong>fspring than those <strong>of</strong> women who do not<br />
take anti-epileptic drugs.<br />
Pharmacogenetics: Oxidation by enzymes<br />
encoded at the CYP2D6 locus is the main route<br />
<strong>of</strong> elimination for a large number <strong>of</strong> drugs<br />
including many commonly prescribed in<br />
psychiatric practice such as antidepressants <strong>and</strong><br />
neuroleptics. The CYP2D6 locus is highly<br />
polymorphic <strong>and</strong> numerous mutant CYP2D6<br />
alleles are currently known including defective<br />
alleles which yield no functional protein product<br />
<strong>and</strong> duplicated active alleles which cause<br />
ultrarapid oxidation. Two CYP2D6 oxidation<br />
phenotypes EM (extensive metabolisers) <strong>and</strong> PM<br />
(poor metabolisers) are commonly recognized.<br />
These phenotypes can be accurately predicted<br />
by genotyping. The clinical implications <strong>of</strong> the<br />
CYP2D6 polymorphism are <strong>of</strong> potential<br />
importance to psychiatric practice in the UAE<br />
since tricyclic antidepressants are widely<br />
prescribed for treatment <strong>of</strong> depression. These<br />
drugs have a small therapeutic index <strong>and</strong><br />
unpleasant side-effects or therapeutic failure is<br />
commonly encountered when fixed dose<br />
regimens are used. There are only very few <strong>and</strong><br />
conflicting data concerning the distribution <strong>of</strong><br />
CYP2D6 phenotypes in Arab populations <strong>and</strong> no<br />
genotyping studies have ever been carried out.<br />
We aim to determine the frequency <strong>of</strong> the most<br />
common CYP2D6 alleles in the local population<br />
using allele specific PCR methodology <strong>and</strong> to<br />
assess the relevance <strong>of</strong> the CYP2D6<br />
polymorphism to psychiatric practice in the UAE.<br />
Dr. Murat Ahmed Oz<br />
<strong>Research</strong> interest <strong>of</strong> Dr. Oz focuses on the<br />
identification <strong>of</strong> ion channels <strong>and</strong> neuronal<br />
networks upon which neuropharmacologically<br />
active agents act to modulate neuronal<br />
excitability. To this end, actions <strong>of</strong> neuropeptides<br />
such as vasopressin, angiotensin, <strong>and</strong><br />
cholecystokinin on the spinal cord preparations<br />
<strong>and</strong> the effects <strong>of</strong> bioactive lipids such as<br />
endocannabinoids on the functions <strong>of</strong> ion<br />
channels are the major research topics<br />
investigated in his laboratory.<br />

Cancer research<br />
My research is focused on the role <strong>of</strong><br />
PI3K/Akt/NFKB‚ pathway as a driving force behind<br />
lung <strong>and</strong> colon cancer progression (apoptosis,<br />
invasion, angiogenesis <strong>and</strong> metastasis) using<br />
siRNA technology <strong>and</strong> in parallel screening <strong>of</strong><br />
potential anti-cancer drugs.<br />
1. Identification <strong>of</strong> Akt is<strong>of</strong>orms involved in<br />
colon cancer survival <strong>and</strong> invasion<br />
The PI3K/Akt/NFKB signaling cascade is<br />
constitutively activated in cancers. Akt is linked<br />
to the transforming activity <strong>of</strong> c-src, c-kit, c-met<br />
oncogenes <strong>and</strong> growth factors, such as EGF <strong>and</strong><br />
