Effects of Pulsatile Intravenous Follicle-Stimulating Hormone Treatment on Ovarian Function in Women With Obesity
Luu et al., Fertility and Sterility. 2023.
https://pubmed.ncbi.nlm.nih.gov/37276947/
By performing intravenous (IV) administration of pulsatile recombinant follicle-stimulating hormone (FSH), researchers established conditions for effective hypothalamic suppression in women with normal and high body mass index (BMI). In women with obesity, the treatment resulted in E2 and inhibin B levels comparable to those in normal-weight women. This work offers a potential strategy to mitigate some of the adverse effects of high BMI on fertility, assisted reproduction, and pregnancy outcomes. Supported by ORIP (K01OD026526), NIA, and NICHD.
Stromal P53 Regulates Breast Cancer Development, the Immune Landscape, and Survival in an Oncogene-Specific Manner
Wu et al., Molecular Cancer Research. 2022.

Loss of stromal p53 function drives tumor progression in breast cancer, but the exact mechanisms have been relatively unexplored. Using mouse models, researchers demonstrated that loss of cancer-associated fibroblast (CAF) p53 enhances carcinoma formation driven by oncogenic KRAS G12D, but not ERBB2, in mammary epithelia. These results corresponded with increased tumor cell proliferation and DNA damage, as well as decreased apoptosis, in the KRAS G12D model. Furthermore, a gene cluster associated with CAF p53 deficiency was found to associate negatively with survival in microarray and heat map analyses. These data indicate that stromal p53 loss promotes mammary tumorigenesis in an oncogene-specific manner, influences the tumor immune landscape, and ultimately affects patient survival.
