Identification of UBE2T as a novel diagnostic biomarker of psoriasis and proliferating UBE2T+ Keratinocyte in psoriasis.
Article in Journal of translational medicine, 2026. 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
backgroundPsoriasis is a chronic, inflammatory autoimmune skin disease, characterized by epidermal hyperplasia and abnormal immune system activation. It is influenced by both genetic and environmental factors.
methodsWe identified hub genes associated with activated CD8 + T cell infiltration in psoriatic skin using machine learning algorithms. A LASSO regression model for psoriasis diagnosis was constructed based on these hub genes. Single-cell analysis identified a UBE2T+ Keratinocyte subpopulation, and spatial transcriptomics determined its location in the stratum spinosum. Additionally, in vitro experiments were conducted using a psoriatic keratinocyte cell model to assess the expression levels of UBE2T and its impact on cell proliferation and IL23A expression.
resultsActivated CD8 + T cells were significantly infiltrated in psoriatic skin. UBE2T was identified as a hub gene linked to activated CD8 + T cell infiltration. The UBE2T+ Keratinocyte subpopulation was located in the stratum spinosum of the epidermis, with the potential to differentiate into the UBE2T- Keratinocyte subpopulation. In vitro, UBE2T overexpression in HaCaT cells led to increased proliferation and upregulation of IL23A, a key pro-inflammatory factor.
conclusionsUBE2T may serve as a potential diagnostic marker for psoriasis. The UBE2T+ Keratinocyte subpopulation is associated with excessive keratinocyte proliferation and inflammation, suggesting it could be a prospective target for psoriasis treatment.
