Background: Evidence increasingly indicates that HPV infection plays a pivotal role in the initiation and progression of bladder cancer (BC). Yet, determining the predictive value of HPV-associated genes in BC remains challenging. Methods: We identified differentially expressed HPV-associated genes of BC patients from the TCGA and GEO databases. ⋯ Risk scores were correlated with tumor microenvironment (TME) scores, immune cell infiltration, and sensitivities to both chemotherapy and immunotherapy. Conclusion: We have formulated a risk-assessment model pinpointing 13 central HPV-associated genes in BC. These genes present potential as prognostic indicators and therapeutic targets, emphasizing the intertwined relationship between HPV-induced BC progression and the immune landscape.

Purpose: To evaluate the association between coronary heart disease (CHD) severity and the risk of developing keratopathy. Method: A retrospective cohort study was conducted with data from the Taiwan National Health Insurance Research Database (NHIRD). A total of 593100, 593100 and 296500 patients were included in the control, mild CHD and severe CHD groups, respectively. ⋯ The cumulative incidence of superficial keratopathy was also significantly greater in the severe CHD group than in the mild CHD group (P < 0.001). In the subgroup analyses, the incidence of superficial keratopathy was significantly greater in severe CHD patients than in mild CHD patients older than 70 years, and the correlation between CHD severity and superficial keratopathy incidence was significantly greater in those older than 70 years of age (P = 0.002). Conclusions: Severe CHD is related to a greater risk of developing superficial keratopathy, especially in those older than 70 years of age.

Background: A more accurate assessment of extrahepatic metastases (EHMs) with colorectal cancer liver metastases (CRLMs) improve patient prognosis without unnecessary surgery and economic burden. At present, PET-CT can only be used as a second-line modality. We aimed to construct a predictive model for EHMs, and provide guidance for the selective application of 18F-FDG PET/CT. ⋯ The nomogram model achieved stable and accurate prediction results in the training and validation sets (AUC = 0.768 and 0.733), and was significantly superior to CEA and CA19-9. Moreover, the sensitivity and specificity of 18F-FDG PET/CT for the diagnosis of EHMs were 100% and 88%, respectively. Conclusions: We constructed and validated a nomogram on predicting the risk of EHMs in patients with CRLMs, which can guide clinicians to selective application of 18F-FDG PET/CT.

Growing research suggests that endometriosis and systemic lupus erythematosus (SLE) are both chronic inflammatory diseases and closely related, but no studies have explored their common molecular characteristics and underlying mechanisms. Based on GEO datasets, differentially expressed genes in the endometriosis cohort and the SLE cohort were screened using Limma and weighted gene co-expression network analysis (WGCNA), and prediction signatures were constructed using LASSO logistic regression analysis, respectively. Four co-diagnostic genes (PMP22, QSOX1, REV3L, SP110) were identified for endometriosis and SLE. ⋯ Multifactor regulatory network of four co-diagnostic genes was constructed including 96 TFs, 42 miRNA, 43 lncRNA, and 189 drugs, and Tributyrin was found to act on four co-diagnostic genes simultaneously. We identified and validated four co-diagnostic genes and revealed the potential molecular mechanisms of endometriosis and SLE, which is helpful for early diagnosis and targeted therapy. Our study provides a novel perspective for individualized treatment of patients with endometriosis and SLE.

Nucleus accumbens-associated protein 1 (NACC1) regulates various types of biological processes. It is a transcription factor associated with cancer. NACC1 is overexpressed in many human malignancies and can regulate the progression, metastasis, and drug resistance of cancer cells. ⋯ Concurrently, ADAM9 knockdown affected the activity of AML cells by decelerating the growth rate, promoting apoptosis, and blocking cell cycle progression. In addition, the AKT activator SC79 restored the inhibited cell proliferation after NACC1 knockdown and ADAM9 knockdown. In conclusion, our study suggested that the NACC1/ADAM9/PI3K/AKT axis is crucial for sustaining the survival of AML cells, indicating that NACC1 may be a viable target for treating AML.
