This gives researchers a way not only to eliminate a mutated gene sequence, but to influence how the gene is expressed and regulated. Such targeted editing could one day be useful for treating genetic diseases caused by mutations in the genome, such as Duchenne’s muscular dystrophy, Huntington’s disease or some cancers.Nowhere to hide: Molecular probe illuminates elusive cancer stem cells in live miceAug 1, 2018 9:00 am1520 views After a primary tumor is treated, cancer stem cells may still lurk in the body, ready to metastasize and cause a recurrence of the cancer in a form that’s more aggressive and resistant to treatment. University of Illinois researchers have developed a molecular probe that seeks out these elusive cells and lights them up so they can be identified, tracked and studied not only in cell cultures, but in their native environment: the body. In a paper published in the journal ACS Central Science, the researchers described the probe’s effectiveness in identifying cancer stem cells in cultures of multiple human cancer cell lines as well as in live mice.Study explores risk factors linked to chikungunya and dengue outbreaksJul 24, 2018 8:15 am758 views In one of the largest studies of its kind, researchers analyzed chikungunya and dengue outbreak data from 76 countries over a period of 50 years, focusing on regions across the Indian Ocean that are hard hit by these and other mosquito-borne infectious diseases.In rats, perinatal exposure to phthalates impairs brain structure and functionJul 18, 2018 1:00 pm936 views Male and female rats exposed in the womb and during lactation to plasticizing chemicals known as phthalates had significantly fewer neurons and synapses than those that were not exposed, researchers report in a new study.
