8, 2015 – – Scientists survey that a common gene variant may be linked to both early pregnancy reduction and failed in vitro fertilization treatments. The variant in a woman’s genome, which causes errors in the cell replication process, is strongly associated with risk of aneuploidy – – an abnormal number of chromosomes in a cell, the researchers said. But they did not prove that the variant causes pregnancy complications. ‘Early in human advancement, this [cell replication] process is particularly error-prone, affecting as many as 75 % of embryos and often causing pregnancy loss as soon as five times after fertilization – – prior to the mother also knows she is pregnant,’ study 1st author Rajiv McCoy, a postdoctoral researcher at the University of Washington in Seattle, said in a news release from the American Culture of Human Genetics.‘RRM2 was defined as an unfavorable prognostic marker inside our study population and this is in agreement with its crucial function in providing deoxyribonucleotides for DNA synthesis and restoration and with the finding that cells overexpressing RRM2 exhibit improved cellular invasiveness,’ Dr Dal Bello explained. Due to the speedy and high recurrence price of lung cancer, prognostic markers to identify patients with higher threat of relapse represent a higher unmet medical want.
