Genetic insights into biological mechanisms governing human ovarian ageing

28 September 2021

Abstract Reproductive longevity is essential for fertility and influences healthy ageing in women 1 , 2 , but insights into its underlying biological mechanisms and treatments to preserve it are limited. Here we identify 290 genetic determinants of ovarian ageing, assessed using normal variation in age at natural menopause...

New study explores the links between prenatal sex steroid hormones, maternal health and autism

28 September 2021

New research from the Autism Research Centre and the Rosie Hospital, both at the University of Cambridge, suggests that maternal steroid factors during pregnancy are associated with autistic traits in mothers and their infants. Previous studies have shown a relationship between prenatal sex steroid hormones and the...

Reconstructing aspects of human embryogenesis with pluripotent stem cells

22 September 2021

Berna Sozen,Victoria Jorgensen,Bailey A. T. Weatherbee,Sisi Chen,Meng Zhu & Magdalena Zernicka-Goetz Abstract Understanding human development is of fundamental biological and clinical importance. Despite its significance, mechanisms behind human embryogenesis remain largely unknown. Here, we attempt to model human...

Insulin increases adipose adiponectin in pregnancy by inhibiting ubiquitination and degradation: Impact of obesity

17 September 2021

Irving L M H Aye , Fredrick J Rosario , Anita Kramer , Oddrun Kristiansen , Trond M Michelsen , Theresa L Powell , Thomas Jansson Abstract Context Circulating adiponectin levels are decreased in pregnant women with obesity or gestational diabetes, and this is believed to contribute to the insulin resistance and increased...

Antonia Hufnagel , Denise S. Fernandez-Twinn , Heather L. Blackmore , Thomas J. Ashmore , Robert A. Heaton , Benjamin Jenkins , Albert Koulman , Iain P. Hargreaves , Catherine E. Aiken , Susan E. Ozanne Abstract Maternal obesity is a global problem that increases the risk of short- and long-term adverse outcomes for mother...

Excessive endoplasmic reticulum stress drives aberrantmouse trophoblast differentiation and placentaldevelopment leading to pregnancy loss

10 September 2021

Nadejda Capatina , Myriam Hemberger , Graham Burton , Erica Watson , and Hong Wa Yung Key points Endoplasmic reticulum (ER) stress promotes placental dysmorphogenesis and is associated with poor pregnancy outcomes. We show that unfolded protein response signalling pathways located in the ER drive differentiation of mouse...

Roger Short, one of the giants of the field of reproductive biology has sadly passed away

12 August 2021

roger_short_2.jpg Image credit: The History of Modern Biomedicine It is with great sadness that we hear of the passing of Roger Short, one of the giants of the field of reproductive biology. Roger’s research interests were broad, but notably he pioneered assays for measuring sex steroids and elucidated their effects on...

Placental mitochondrial function, nutrient transporters, metabolic signalling and steroid metabolism relate to fetal size and sex in mice

26 July 2021

Esteban Salazar-Petres, Daniela Pereira Carvalho, Jorge Lopez-Tello, Amanda Nancy Sferruzzi-Perri Abstract Fetal growth depends on placental function, which requires energy supplied by mitochondria. Here we investigated whether mitochondrial function in the placenta relates to growth of the lightest and heaviest fetuses of...
