Pregnancy-associated shifts in maternal microbiota across multiple body sites can signal to the placenta, influencing its function and fetal development.

Maternal microbial ecosystems are key in shaping reproductive physiology and pregnancy outcomes. While the gut microbiota has been extensively studied, the roles of microbes in other body regions are less clear. This #IAIJournal review provides insights: asm.social/2OQ

Figure 3: CCNA2 protein expression is downregulated during the transition from mitosis to meiosis by MEIOC and STRA8. (C) Labeling of CCNA2 in DDX4-positive oogenic cells from wild-type, Stra8 knockout, Meioc knockout and Meioc Stra8 double knockout (dKO) ovaries at E16.5. Arrows and arrowheads mark EdU-positive and -negative oogenic cells, respectively. Meioc Stra8 double knockout panel also appears in Fig. 1B. Scale bar: 20 µm. (D) Quantification of CCNA2 intensity in EdU-positive and -negative oogenic cells. Data for EdU-positive cells represents 190 cells from five wild-type embryos, 35 cells from five Stra8 knockout embryos, 144 cells from three Meioc knockout embryos and 124 cells from three Meioc Stra8 double knockout embryos. Data for EdU-negative cells represents 2492 cells from five wild-type embryos, 579 cells from five Stra8 knockout embryos, 909 cells from three Meioc knockout embryos and 296 cells from three Meioc Stra8 double knockout embryos. Dot represents the median; whiskers represent the interquartile range. *adj. P<0.05; **adj. P<0.01; ****adj. P<0.0001. See Table S4 for statistical details.

Reaffirming the value of model organisms in training scientific minds - Nature Cell Biology As biomedical research prioritizes human models and translational promise, classic model organisms are increasingly dismissed. Here we argue that they have a lasting value, both in enabling discovery and in cultivating scientific thinking, by training researchers in systems reasoning, integrative thinking and independent inquiry.
