 E-Mail Cells from healthy individuals with major depressive disorder were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study by a multidisciplinary team of Walter Reed Army Institute of Research and University of California San Francisco scientists, in collaboration with others. Methylation is a process by which DNA is chemically modified at specific sites, resulting in changes in the expression of certain genes. Methylation of particular sets of genes, called "DNA methyla...

‘It was like rolling the dice, except for someone you’ve never met.’ Credit...Karolin Schnoor April 6, 2021, 5:00 a.m. ET My husband and I were sitting in an Upper East Side office with deep-toned velvet couches and fluffy throw pillows, surrounded by photos of smiling babies, as the fertility doctor gave his spiel. He told us that after age 35, a woman’s chances of getting pregnant drop. Older women produce few normal embryos even with fertility treatment. But we’d have a healthy baby in our arms within a year — if we tested the embryos. By testing the chromosomes in my embryos, ...

 E-Mail New Haven, Conn. -- In a new study, Yale Cancer Center researchers have defined the genetic landscape of uterine leiomyosarcomas (uLMS). Furthermore, using fully sequenced patient-derived xenografts, the team has preclinically validated new treatment modalities, which may point to new treatments for uterine cancer. Study results were published online in an early edition of the Proceedings of the National Academy of Science (PNAS). Uterine cancer is the most common gynecologic malignancy and uterine leiomyosarcomas (uLMS) are highly lethal sarcomas arising from the myometrium, the sm...

Black women have 80% higher risk of preterm birth between 32 and 33 weeks of pregnancy if a Black person who lives in their neighborhood is killed by police during the pregnancy, according to a study by researchers at UC San Francisco and UC Berkeley.
