Multi-omics reveals that NOTCH1 promotes cervical cancer progression and reduces radiosensitivity.

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
Background: Cervical cancer is the fourth most common malignancy in women globally. The NOTCH signaling pathway is aberrantly activated in multiple tumors, and NOTCH1, its core transmembrane receptor, is highly expressed in cervical cancer. However, NOTCH1's mechanisms in cervical cancer progression and radiotherapy resistance, as well as its interaction with key molecules, remain unclear. Methods: This study explored the role of NOTCH1 in cervical cancer from multi-omics perspectives, including single-cell sequencing, cDNA microarrays, high-throughput sequencing, and immunohistochemistry, combined with a series of in vitro and in vivo experiments. Results: NOTCH signaling activity was negatively correlated with the overall survival and recurrence-free survival of cervical cancer patients. As the core molecule of this signaling pathway, NOTCH1 was significantly highly expressed in cervical cancer tissues and promoted cervical cancer cell proliferation in vitro. Single-cell analysis revealed that NOTCH1 was relatively highly expressed in CPA6+ and CEL+ malignant cells and involved in cell cycle regulation; further cell cycle detection assays confirmed that NOTCH1 could promote the G1-S phase transition. In addition, patients with high NOTCH1 expression showed decreased plasma cell infiltration in the microenvironment. Cell communication analysis indicated that malignant cells with high NOTCH1 expression might lead to impaired plasma cell differentiation due to the impairment of the MIF ligand-receptor pathway. Finally, NOTCH1 could reduce the radiosensitivity of cervical cancer cells to radiotherapy both in vitro and in vivo; whereas has-miR-449a, as an upstream regulatory miRNA of NOTCH1, could inhibit cervical cancer cell proliferation and enhance radiosensitivity by inhibiting NOTCH1 expression. Conclusions: This study clarifies NOTCH1's role in promoting cervical cancer progression and reducing radiosensitivity, with has-miR-449a as a negative regulator, providing targets for optimizing cervical cancer radiotherapy.
