Senolytics alleviate cyclophosphamide-induced premature ovarian insufficiency by eliminating senescent cells.

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
Alkylating agents, particularly cyclophosphamide (CY), are known for their high toxicity, which can lead to iatrogenic premature ovarian insufficiency (POI) and infertility in young cancer survivors. Currently, effective prevention and treatment strategies remain limited. Given that chemotherapy induces cellular senescence, we investigated the therapeutic potential of dasatinib (D) and quercetin (Q), a senolytic combination known to eliminate senescent cells. Using a CY-induced murine model of ovarian injury, we found that CY treatment increased the accumulation of senescent cells in the ovaries. The resulting senescence-associated secretory phenotype (SASP) led to a deterioration of the ovarian microenvironment, characterized by increased follicular atresia and a decline in follicle quantity, ultimately culminating in POI. Our findings demonstrate that DQ therapy effectively mitigated CY-induced damage by clearing senescent cells and reducing SASP secretion. Clinically, DQ administration restored sex hormone levels and regularity of the estrous cycle, resulting in an overall increase in follicle numbers across all developmental stages. Furthermore, DQ treatment significantly normalized estrous cyclicity, restoring regular cycles in 60% of the CY+DQ mice compared to only ~15% in the CY-alone group (p<0.0001). RNA sequencing analysis revealed that DQ treatment upregulated Pagr1a, a gene associated with extraembryonic development, while downregulating genes involved in senescence induction (Itgb3, Wnt10b, Vegfa) and immune function (A2m, Ccl21d). These results suggest that senescent cells drive CY-induced ovarian damage and that DQ represents a promising therapeutic strategy for preserving the ovarian reserve and endocrine function in female cancer patients.
