Brain-specific Gata4 downregulation in Greywick female mice models the metabolic subtype of polycystic ovary syndrome

S. A. Nawaito, M. Esmael, O. Souchkova, T. Cardinal, G. Bernas, K.-F. Bergeron, F. Gayda, F. Bergeron, M.-F. Bouchard, X. Zhou, L. Ongaro, D. J. Bernard, J. Short, S. Wray, R. S. Viger, , N. Pilon

This study shows that Gata4 downregulation in the hypothalamus of Greywick female mice models the metabolic subtype of PCOS by affecting fertility and food intake genes.

Activin E is a TGFβ ligand that signals specifically through activin receptor-like kinase 7.

K. A. Vestal, C. Kattamuri, M. Koyiloth, L. Ongaro, J. A. Howard, A. Deaton, S. Ticau, A. Dubey, D. J. Bernard, T. B. Thompson

This study identifies Activin E as a TGFβ ligand that signals through ALK7, using canonical activin receptors and SMAD2/3 pathways, similar to Activin C.

Myostatin is a major endocrine driver of follicle-stimulating hormone synthesis

L. Ongaro, X. Zhou, Y. Wang, Z. Zhou, H. Schultz, E. R. S. Buddle, E. Brule, Y.-F. Lin, G. Schang, R. Castonguay, Y. Liu, G. H. Su, N. Seidah, K. C. Ray, S. J. Karp, , D. J. Bernard

The paper identifies myostatin as an endocrine hormone that promotes pituitary FSH synthesis and ovarian function, challenging the previous role of activins and highlighting potential fertility risks of myostatin antagonists.

The orphan ligand, Activin C, signals through activin receptor-like kinase 7

E. J. Goebel, L. Ongaro, E. C. Kappes, E. Belcheva, R. Castonguay, R. Kumar, D. J. Bernard, T. Thompson

This study characterizes the signaling properties of Activin C and its heterodimer ActAC, showing they activate SMAD2/3 via ALK7 with distinct receptor and antagonist profiles compared to ActA and ActB.
