Flaws in six genes could help report replica

why parts of southern China have extraordinarily high rates of a kind of nose-and-

throat cancer, scientists said on Sunday.Specialists from China, Singapore and the United States

trawled through a genetic datamine of around 10,000 people of southern Chinese descent.



Half of the volunteers had cartier replica

been diagnosed with nasopharyngeal carcinoma, a cancer that forms in the lining of the

upper throat lying behind the nose. The other half were zhjchv0601 otherwise healthy.What showed up

in the cancer group were telltale variants in six genes, according to the research, reported in the

journal Nature Genetics.



The six, named TNFRSF19, MDSIEVI1 Replica Vertu and

CDKN2A/2B, have been historicallyin the past linked with leukaemia.Another pointer in the cancer

patients was a variation in the human leukocyte antigen (HLA) gene, which has historicallyin the

past been fingered in this illness.



The findings are important, says replica

the study, as they could shed light on the molecular pathways of

nasopharyngeal carcinoma and its high prevalence in southern China, Guangdong province.In this

region, the cancer occurs in about 25 cases per 100,000 people, which is 25 times higher than the

remainder of the world.



As a result, nasopharyngeal replica handbags

carcinoma is sometimes called the "Cantonese cancer."Only Alaska, parts of northern Africa and

southeastern Asia have similarly high rates.The research was led by the Genome Institute of

Singapore and the Sun Yat-Sen University Cancer Centre in Guangzhou.

lifestyle as well as inherited factors. Smoking, in particular, is a major

cause. In nasopharyngeal carcinoma, consumption of salted and pickled foods as well as high levels

in the blood of Epstein-Barr virus are additionally in the spotlight.
