Abstract
Endometrial cancer is considered to be the second most common tumor of the female reproductive system, and patients diagnosed with advanced endometrial cancer have a poor prognosis. The influence of fatty acid metabolism in the prognosis of patients with endometrial cancer remains unclear. We constructed a prognostic risk model using transcriptome sequencing data of endometrial cancer and clinical information of patients from The Cancer Genome Atlas (TCGA) database via least absolute shrinkage and selection operator regression analysis. The tumor immune microenvironment was analyzed using the CIBERSORT algorithm, followed by functional analysis and immunotherapy efficacy prediction by gene set variation analysis. The role of model genes in regulating endometrial cancer in vitro was verified by CCK-8, colony formation, wound healing, and transabdominal invasion assays, and verified in vivo by subcutaneous tumor transplantation in nude mice. A prognostic model containing 14 genes was constructed and validated in 3 cohorts and clinical samples. The results showed differences in the infiltration of immune cells between the high-risk and low-risk groups, and that the high-risk group may respond better to immunotherapy. Experiments in vitro confirmed that knockdown of epoxide hydrolase 2 (EPHX2) and acyl-CoA oxidase like (ACOXL) had an inhibitory effect on EC cells, as did overexpression of hematopoietic prostaglandin D synthase (HPGDS). The same results were obtained in experiments in vivo. Prognostic models related to fatty acid metabolism can be used for the risk assessment of endometrial cancer patients. Experiments in vitro and in vivo confirmed that the key genes HPGDS, EPHX2, and ACOXL in the prognostic model may affect the development of endometrial cancer.

Abstract
Memory control (MC) and emotion regulation (ER) are critical cognitive functions for adapting to life's challenges, drawing significant research attention. Accumulating evidence suggests these processes are interrelated, yet a comprehensive discussion of their interplay remains lacking. We introduce an integrative framework exploring the mutual influence between MC and ER, composed of two interrelated branches: first, MC aids in ER through the retrieval of positive memories, intentional forgetting of undesirable content, and the adaptive updating of memory stores. Second, ER impacts MC by upregulating positivity and downregulating negativity in memories. The framework spotlights the need to harness MC-ER interplay for future research. Potential directions include utilizing MC to amplify ER capabilities, training ER skills to refine MC performance, and modulating the cognitive and neural overlapping of both processes to improve both functions. Delving into the MC-ER nexus advances understanding of the intricate emotion-memory relationship and holds great promise for developing novel behavioral interventions.

Song C, Liu L, Wang W. Distinguishing pathways from bullying victimization to nonsuicidal self-injury and to cyberaggression: Do perceived ostracism and depression mediate their links? Stress Health 2023. [PMID: 37876136 DOI: 10.1002/smi.3337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
Bullying victimization is related to increased aggressive behaviour, but little research considers both self- (e.g., nonsuicidal self-injury; NSSI) and other-directed (e.g., cyberaggression) outcomes. Moreover, little is known about the mediating mechanisms that underlie this relationship. Based on the General Aggression Model, the current study investigates the mediating roles of Perceived ostracism (PO) and depression in the relationship between bullying victimization and cyberaggression/NSSI among emerging adult. A total of 795 emerging adults (Mage = 19.66 years, SD = 1.46; 59.9% female) completed a multimeasure questionnaire measuring the targeted variables at three time points over one year. Structural equation modelling was used to test temporal mediation. After controlling for gender, age, and family monthly income, bullying victimization was found to positively predict later cyberaggression and NSSI. Mediation analysis revealed that the longitudinal association between bullying victimization and cyberaggression was mediated by PO; the longitudinal association between bullying victimization and NSSI was mediated by depression and was sequentially mediated by PO and depression. These findings extend the theory, prevention and interventions to include both self- and other-directed aggressive behaviour in the bullying context. Future research and practice may benefit from an emphasis on PO and depression-focused psychological interventions.
