Malaria is a leading cause of death in tropical and subtropical regions and it is transmitted by a bite from infected female mosquitoes. According to the U.S. Centers for Disease Control, malaria claims nearly 660,000 lives per year, 90% of them in Africa—and most of them children. There were an estimated 216 million malaria cases worldwide in 2010, mostly among pregnant women and children. Despite the efforts to develop a vaccine, there is still not an effective one thus other strategies,...

Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in preparation for the highly asymmetric cell division that completes oocyte maturation upon fertilization of the egg, report researchers at the Stowers Institute for Medical Research. Their findings illustrate how oocytes repurposed a dynamic cellular mechanism capable of generating considerable...

Researchers at Brown University and Women & Infants Hospital have invented the first artificial human ovary, an advance that provides a potentially powerful new means for conducting fertility research and could also yield infertility treatments for cancer patients. The team has already used the lab-grown organ to mature human eggs. "An ovary is composed of three main cell types, and this is the first time that anyone has created a 3-D tissue structure with triple cell line," said Sandra...

Two enzymes called extracellular signal-regulated kinases (ERK1 and ERK2) are critical factors in a pathway that induces ovulation, maturation of the mammalian egg (oocyte) and other activities key to ovarian function and female fertility, said a group of researchers at Baylor College of Medicine (BCM) in a report that appears today in the journal Science."This finding could provide clues to developing new contraceptives and understanding infertility in some women with irregular menstrual...
