Mutation Leads To Male Infertility Paper reports that a mutation in a gene called AURKC (Aurora Kinase C) has been identified in 14 infertile men of North African descent.
Genetic Susceptibility To Crohn Disease A genome-wide assessment of genetic variation in individuals with Crohn disease has identified seven genes or regions that are associated with elevated risk of the disease.
Genes Linked To Chemotherapy Response Scientists have identified a number of genes in lung cancer cells which, when downregulated, make the cancer cells especially vulnerable to a type of chemotherapy.
Genes Set Scene For Metastasis Biologists have identified a set of genes expressed in human breast cancer cells that work together to remodel the vasculature at the site of the primary tumour and that also promote the spread of cancer to the lungs.
