Expression of nicastrin, NICD1, and Hes1 in NCSTN knockout mice: implications for hidradenitis suppurativa, Alzheimer's, and liver cancer.
Article in European journal of medical research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundNicastrin, a subunit of the γ-secretase complex, is encoded by the NCSTN gene and regulates notch signaling, it is involved in the pathogenesis of hidradenitis suppurativa (HS), Alzheimer disease (AD), and liver cancer. However, the animal models for studying HS are relatively scarce.
methodsCRISPR/Cas-mediated genetic engineering was used to generate targeted knockout offspring mice (C57BL/6J). Different doses (10 mg/kg, 20 mg/kg, and 30 mg/kg) and injection methods (subcutaneous/intraperitoneal/gavage injection) of tamoxifen were used to induce the construction of NCSTN knockout mice (mice model). The expressions of nicastrin, NICD1, hes1 in skin, brain, and liver tissue in mice model and wild-type (WT) mice were measured by qRT-PCR and IHC.
resultsThe construction of mice model was successfully induced by tamoxifen, knockout efficiency was 93%, there was no difference in knockout efficiency among three doses, injection methods, genders (P > 0.05). HS-like lesions appeared on the skin of NCSTN knockout mice after 1 month of treatment with tamoxifen, male mice had a higher number of skin lesions compared to female mice (male vs female = 76.5% vs 41.7%, P = 0.027). Compared with WT mice, the expressions of nicastrin (skin P = 0.0009, brain P = 0.0194, liver P = 0.0066), NICD1 (skin P = 0.0115, brain P = 0.0307, liver P = 0.008), hes1 (skin P = 0.0476, brain P = 0.0143, liver P = 0.0003) in mice model all decreased.
conclusionsThe NCSTN knockout mouse might be employed as HS animal model; Reducing nicastrin may affect the expression of notch1-hes1 pathway molecules in skin, brain, and liver tissues; low dose (10 mg/kg/d) tamoxifen could be used to induce the deletion of the target gene in mice.
