Machine learning reveals UHRF-X as a biomarker for systemic lupus erythematosus and an antagonistic protein against UHRF1 E3 ligase
[[abstract]]Inflammatory T cells contribute to the pathogenesis of the autoimmune diseases such as systemic lupus erythematosus (SLE). Analysis of the T-cell transcriptomics data of two independent SLE patient cohorts by three machine learning models revealed UHRF-X as a novel SLE biomarker. T-cell-specific UHRF-X transgenic mice manifested the induction of IL-17A and autoimmune inflammation. Mechanistically, UHRF-X prevented UHRF1-induced Lys48-linked ubiquitination and degradation of MAP4K3 (GLK), which is a kinase known to induce IL-17A. Consistently, IL-17A induction and autoimmune phenotypes of UHRF-X transgenic mice were obliterated by MAP4K3 knockout. Furthermore, UHRF-X protein was indeed overexpressed in peripheral blood T cells of SLE patients. Collectively, UHRF-X overexpression in T cells inhibits the E3 ligase function of UHRF1 and induces IL-17A-mediated autoimmune responses. This report unveils a novel gene that can block UHRF1 function, leading to autoimmune disease
Hepatitis and hepatitis B virus reactivation in everolimus-treated solid tumor patients: A focus on HBV-endemic areas
[[abstract]]Background: Everolimus is approved for treating breast, renal, and pancreatic neuroendocrine cancers but carries the risk of hepatitis B virus (HBV) reactivation (HBVr) and hepatitis. However, data on HBVr in everolimus-treated patients are limited. This study evaluates the risk of hepatitis and HBVr in cancer patients with current or past HBV infection. Methods: This retrospective study analyzed patients prescribed everolimus between 1 January 2011 and 31 May 2022, using a private healthcare system database in Taiwan. Patients with HBsAg positivity or HBsAg negativity and anti-HBs or anti-HBc results were included. The cumulative incidence function and risk of hepatitis from a competing risk model, which estimates Fine-Gray subdistribution hazard (SDH), were analyzed across different HBV serological subgroups. The risk of hepatitis B reactivation was also calculated. Results: Of 377 patients, 45% (36/80) of HBsAg-positive and 0.67% (2/297) of HBsAg-negative patients received nucleos(t)ide analogues (NUCs) prophylaxis. Hepatitis occurred in 28.75% of HBsAg-positive and 17.85% of HBsAg-negative patients. Baseline HBsAg positivity and exemestane use increased hepatitis risk. HBVr occurred in 11.36% (5/44) of HBsAg-positive patients without NUCs and 5.56% (2/36) with prophylaxis. Two HBsAg-negative, anti-HBc-positive patients developed severe HBVr-related hepatitis. Conclusion: Hepatitis occurred in 28.75% of HBsAg-positive and 17.85% of HBsAg-negative patients on everolimus. HBVr was common in HBsAg-positive patients but rare in HBsAg-negative individuals. HBV screening and liver function monitoring are critical for patients with past or current HBV infection receiving everolimus, especially in endemic areas
Long-term exposure to multiple air pollutants and risk of Parkinson's disease: A population-based multipollutant model study
[[abstract]]BACKGROUND: Recent evidence suggests brain-first Parkinson's disease (PD) may start from the olfactory system, indicating potential inhalational exposure to causal agents. We investigated the impact of long-term exposure to various air pollutants on PD incidence using both single- and multi-pollutant models to account for interactions between pollutants. METHODS: This retrospective population study used data from Taiwan's National Health Insurance Research Database (2006 and 2018) and included individuals aged 40-65 without PD. Personal exposure levels to various air pollutants, including PM(2.5), PM(10), NO(2), O(3), SO(2) and CO, were calculated using the hybrid Kriging/land-use regression method. Cox regression models were used to analyse the association between pollutants and PD incidence, adjusting for covariates. RESULTS: A total of 5 113 322 individuals without PD (mean age 50.1±6.9 years, 47.3% men) were followed for an average of 11.2±2.4 years, during which 20 694 incident cases of PD were identified. In the single-pollutant model, exposure to PM(2.5) (HR 2.65 (95% CI 2.59 to 2.72)), PM(10) (HR 3.13 (3.04 to 3.22)), NO(2) (HR 1.74 (1.68 to 1.80)) and SO(2) (HR 1.68 (1.65 to 1.71)) was associated with an increased risk of PD. These associations remained robust in the multipollutant model. A positive association between exposure to O(3) and an increased risk of PD (HR 1.29 (1.25-1.33)) was observed after adjusting for co-pollutants. CONCLUSIONS: This nationwide cohort study employing multiple-pollutant models for considering the interaction effects revealed an association between exposure to multiple air pollutants and the risk of PD, emphasising the need for early prevention strategies
Advancing precision therapy for colorectal cancer: Developing clinical indications for multi-target kinase inhibitor BPR1J481 using patient-derived xenograft models
[[abstract]]The large and rapid increase in the incidence and mortality of colorectal cancer (CRC) demonstrates the urgent need for new drugs with higher efficacy to treat CRC. However, the lack of applicable and reliable preclinical models significantly hinders the progress of drug development. Patient-derived xenograft (PDX) models are currently considered reliable in vivo preclinical models for predicting drug efficacy in cancer patients. This study successfully uses the CRC PDX model to develop clinical indications for the new multi-target kinase inhibitor BPR1J481 and demonstrated the anti-cancer mechanism and competitive advantages of this drug candidate. The results demonstrate that BPR1J481 exhibits significant anticancer efficacy by inducing apoptosis in CRC PDX tumor tissues and corresponding PDX-derived CRC cells. Through kinase competitive binding and kinase activity assays, we discover that BPR1J481 effectively inhibits SRC kinase activity by directly binding to its active site. The reduction in SRC phosphorylation observed in CRC PDX tumor tissues and derived cells upon treatment with BPR1J481 further validates its inhibitory potential. Furthermore, the decrease in viable cells after SRC knockout and the poorer prognosis observed in patients with higher SRC expression, emphasizes the critical significance and clinical relevance of SRC in CRC. Additionally, BPR1J481 exhibits robust anti-angiogenic effects by suppressing VEGF- and PDGF-induced endothelial cell proliferation, migration, and capillary-like tube formation through inhibition of VEGFR2 and PDGFRβ phosphorylation. Remarkably, BPR1J481 appears to demonstrate greater efficacy against CRC compared to regorafenib. These findings highlight the therapeutic potential of BPR1J481 for patients with CRC
