Spatial and temporal changes in the expression of steroid hormone receptors in mouse model of endometriosis Endometriosis is recognized as a steroid hormone-dependent disorder. However, controversies exist regarding the status of the steroid hormone receptor expression in endometriotic tissues. The purpose of this study was to determine the ontogeny of ...

text "BCBP Seminar Series Presents The RNA Binding protein ZFP36L2 Controls Distinct Gene Programs Across Tissues by Dr. Silvia Ramos who received her MD from the University of Campinas School of Medicine, Campinas, Brazil and completed her residency in Residency Clinical Immunology at the Medical School of Ribeirão Preto. She completed her Masters and Ph.D. in Basic and Applied Immunology at the Medical School of Ribeirão Preto, University of São Paulo, Brazil, and completed her postdoctoral training in mRNA-binding proteins and reproductive biology at the National Institute of Environmental Health Sciences NIEHS-NIH, Research Triangle Park, NC. The Ramos lab’s research is focused on RNA-binding proteins and their physiopathological roles in vivo. Dr. Ramos has a broad medical and biochemical background, with specific training and expertise in RNA-binding proteins and the creation of genetically-engineered mouse models." photo of Dr. Silvia Ramos

Implantation is not just attachment—it’s a coordinated cellular dialogue between embryo and endometrium.
We are only beginning to understand its complexity.

Decoding the pituitary gonadotrope regulatory architecture governing the preovulatory surge in vivo Despite the global burden of female infertility, the molecular control of ovulation remains unclear. Pituitary gonadotropes tune hormonal output to regulate ovarian function, yet the molecular mechani...

Hidden ecosystem of the ovaries plays a surprising role in fertility A woman's fertility declines with age, which is often attributed to a fall in egg number and quality, but the environment of the ovaries themselves may also be responsible

A model for ED organ growth and protein synthesis driven by endoreplication induced by JH signaling. Juvenile hormone signaling (Gce/Met/Tai) induces endoreplication, which induces protein synthesis and ED growth and development, which induce fertility.

In camels, the testicles are located close to the body, in the perineal area, protecting sperm from the high desert temperatures. During heat waves, are human testicles too exposed? Are we not as well adapted to heat as camels?
