Nasopharyngeal carcinoma (NPC) is cancer of the nasopharynx (the uppermost part of the throat that connects the back of the nose to the back of the throat). Published studies suggested genetic predisposition as well as infections by a member of the herpesvirus in the development of NPC. Investigation of both aspects is currently conducted in Universiti Malaysia Sarawak.
Globally, NPC has its highest incidence in South East Asia, and is more prevalent in the Chinese population. Comparison between mainland Chinese and Caucasian showed a 40-fold risk of NPC occurrence in the former.
In Malaysia, the Chinese population represents the highest risk group, constituting 72% of the reported cases. Like most types of cancer, however, the origin of NPC is most probably multifactorial and is specified by several genes. Indeed, other research findings had implicated several genes in NPC tumour progression.
To this date, there are no published studies to correlate the functions, activities and interactions among these genes with regards to the development of NPC. The hypothesis therefore is that there are significant relationships and interactions among these known susceptibility genes (and others?) and their physiological targets in the predisposition and development of NPC.
As the occurrence of NPC is ethnically biased, the genetic background of the susceptible race group probably plays an important role in their predisposition. The question is, what are the genetic markers responsible for these high-risk groups and what are the underlying mechanism(s) of these genetic markers in the predisposition and development of NPC.
On the other hand, Epstein-Barr Virus (EBV) association with NPC has been reported extensively. The tight association indicates a role for EBV in the development of NPC but the mechanism remains unknown, though chromosome rearrangements (specific genetic sequence rearrangements) have been widely detected in NPC cases. While EBV infection and chromosomal rearrangements are commonly observed in NPC, there is no published study looking into their relationship in terms of NPC development.
To unravel the mechanism leading to NPC, a research group in UNIMAS has narrowed their target on the activity of some genes and discovered the involvement of genes that had not been implicated before. The group is also looking at the role of EBV-induced apoptosis in chromosome rearrangements in NPC and their current findings have put support to their hypothesis, qualifying further investigation into other regions of chromosome rearrangements.
It is hoped that the combine outcomes of both studies will give more insight and information to the field of NPC research.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
