Retinoic Acid and Calcitriol Protect Mouse Primordial Follicles from Cyclophosphamide Treatment-Induced Apoptosis.

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
Chemotherapy causes primordial follicle apoptosis, resulting in premature ovarian insufficiency (POI) and infertility. In this study, we found that intraperitoneal injection of retinoic acid (RA) and calcitriol partially reversed the cyclophosphamide and doxorubicin treatment-induced decrease in primordial follicles in neonatal mouse ovaries. Furthermore, RA and calcitriol co-treatment reversed cyclophosphamide treatment-induced PI3K/Akt activity and FOXO3a nuclear export in the oocytes within primordial follicles, suggesting that the oocyte transcriptional activity was decreased, which in turn reduced the binding of chemotherapeutic drugs to DNA. Consistent with these findings, RA and calcitriol co-treatment reversed cyclophosphamide treatment-induced changes in reactive oxygen species (ROS), DNA damage response proteins (γH2AX, p-CHK2, p-p53, PUMA, BAX, Cleaved Caspase-3, and cPARP), and antioxidant proteins (NRF2, HO-1, and GPX4). Moreover, RA and calcitriol co-treatment preserved fertility in cyclophosphamide-treated mice without impairing cyclophosphamide's antitumor efficacy in MCF-7 tumor-bearing mice. Thus, RA and calcitriol protect mouse primordial follicles from cyclophosphamide treatment-induced apoptosis by inhibiting cyclophosphamide treatment-induced oocyte transcriptional activity and enhancing antioxidant capacity. Our results suggest a potential strategy for preserving ovarian reserve during chemotherapy in female cancer patients.
