UBE2T/CDC42/CD276 signaling axis mediates brain metastasis of triple-negative breast cancer via lysosomal autophagy.

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
backgroundAdvanced triple-negative breast cancer (TNBC) is prone to brain metastasis (BrM). The precise molecular mechanism responsible for this phenomenon has not yet been completely established, so it is vital to comprehend the molecular mechanism behind it.
methodsThe protein chip analysis was conducted to identify any abnormal UBE2T protein expression in TNBC, especially BrM. Here, we used public databases and bioinformatics analysis as well as clinical samples from different cohorts to investigate the interrelationship between UBE2T/CDC42/CD276. This predicted relationship was then repeatedly validated using different in vivo and in vitro experimental methods. Additionally, multiple experimental approaches were implemented, encompassing western blotting, Co-IP, GST pull-down, flow cytometry, mass spectrometry, immunofluorescence, immunohistochemistry, and qRT-PCR to reveal the molecular mechanism of UBE2T-mediated immune escape and BrM.
resultsOur results indicate that expressed at elevated levels in breast cancer, UBE2T is negatively linked to patient prognosis, especially in BrM of TNBC. Data from clinical samples from our different cohorts and TCGA indicate a significant correlation between UBE2T and immunosuppression. Mechanistically, UBE2T directly interacts with CDC42, promoting its K48-linked polyubiquitination and proteasomal degradation, thereby inhibiting CDC42 from degrading CD276 via the autophagy-lysosomal pathway, indirectly upregulating CD276 and thereby impairing the CD8
conclusionsIn conclusion, our results indicate a new mechanism whereby UBE2T-mediated ubiquitination positively controls the UBE2T/CDC42/CD276 axis to upregulate tumor cell expression of CD276 and thereby impair CD8
