New research published in Nature Genetics (February 2014) by Qilai Huang and colleagues gives a new insight into the mechanisms by which men with a specific polymorphism (variation in a gene) have increased susceptibility to Prostate Cancer.
The team involving researchers in Finland, Sweden and China found that the ‘rs339331’ polymorphism is located within a functional binding site of the HOXB13 gene and causes an up regulation of RFX6, a protein which is associated with prostate cancer cell proliferation, migration and invasion. Also, their analysis of prostate tumours found a significant association between the T allele at rs339331 and higher levels of RFX6 mRNA.
