The 2nd part of my postdoc is now out as a preprint! A challenging but fulfilling team effort to perform genome editing in opossums. We found that the lncRNA RSX is essential to initiate X-inactivation in marsupials 🦘 A long-standing question since the discovery that Xist is absent in marsupials 👇

New preprint 📢 Thrilled to share our long-awaited work on the role of RSX in marsupial X-inactivation. This was a huge team effort over the years, led by @aureliencourtois.bsky.social @sermenchero.bsky.social Sugako Ogushi and Waz Varsally, that allowed us to set up genome editing in opossum embryos

I got the rejection email today. I didn't have any luck with the Australian Geographic photo comp this year. No need for sympathy. I'm used to it. It's very competitive. Here's one of my unsuccessful entries. A yellow-tailed rock wallaby at Boolcoomatta Reserve.

Awesome to see our paper that explores the role of inflammation during marsupial pregnancy come out @plosbiology.org. We found that embryos secrete inflammatory signals that directly impact embryo survival and nutrient allocation. Explaining why inflammation has been retained in implantation.

Fetal inflammatory signals regulate maternal investment during marsupial pregnancy

Marsupial pregnancy is short and characterized by a spike in inflammation which has been proposed to represent a maternal immune response to fetal contact that limits gestation. This study shows that ...
