Dynamic expression of endometrial adhesion G protein-coupled receptors during the menstrual cycle and early mouse pregnancy: modulation by ovarian stimulation.
Article in F&S science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo characterize the expression of adhesion G protein-coupled receptors (ADGR) in the human endometrium and early mouse pregnancy.
designAn in silico analysis was performed using a retrospective data set comprised endometrial samples across normo-ovulatory menstrual cycles. Gene expression was then validated using quantitative reverse transcription polymerase chain reaction and mRNA sequencing (mRNA-seq) in prospectively collected endometrial biopsies in the periovulatory and midsecretory stages of natural cycles. Gene expression was also investigated under ovarian stimulation (OS) conditions using mRNA-seq. Early pregnancy mouse models were used to investigate whether trends of dynamic ADGR expression are also conserved in the mouse. SUBJECTS: Twenty-four women aged 21-42 years. EXPOSURE: Ovulatory menstrual cycle or OS cycle.
main outcome measuresGene expression in endometrial biopsies and pregnant mouse uterus.
resultsFifteen women, aged 21-33 years, were recruited in natural cycles during the proliferative phase (cycle days 10-13; n = 4), periovulatory (luteinizing hormone + 12-24 hours; n = 6) period, and midsecretory (luteinizing hormone + 8-9 days; n = 5) phase. Nine women aged 31-42 years old undergoing in vitro fertilization (without fresh embryo transfer) or oocyte cryopreservation using a gonadotropin releasing hormone antagonist protocol were recruited for the OS cohort in either the periovulatory phase (human chorionic gonadotropin + 2; n = 5) or midsecretory phase (human chorionic gonadotropin + 9; n = 4). The in silico analysis revealed dynamic expression for many ADGRs across the menstrual cycle. Differential gene expression was also seen in the prospective analysis within the menstrual cycle phases and between natural cycle and OS conditions. Within early mouse pregnancy, expression was also found to be altered across several Adgr subfamilies.
conclusionThe differential gene expression observed between the proliferative and secretory phases of the menstrual cycle, along with changes in expression seen in OS and early mouse pregnancy suggest that ADGR expression is hormonally regulated by estradiol and progesterone.
