Background/aim: It was previously reported that γ-secretase inhibitors (GSIs) enhance taxane-induced mitotic arrest and apoptosis in colon cancer cells. To enable the development of taxane-based chemotherapy for pancreatic ductal adenocarcinoma (PDAC), this study investigated the molecular mechanisms by which γ-secretase (GS) complexes regulate taxane sensitivity.
Materials And Methods: The effect of GS complexes on taxane-induced apoptosis in PDAC cells was evaluated by a cell cycle analysis. GS complexes were examined with small interference RNAs targeted to GS complex-related genes.
Results: GSIs and silencing of presenilin 1 (PS1) did not affect cell proliferation but resulted in enhanced taxane-induced G(2)/M accumulation and apoptosis. Silencing of the Notch gene did not induce these effects. However, PS2-specific silencing suppressed proliferation and taxane-induced apoptosis.
Conclusion: Data from this study indicate that GS complexes regulate the response of PDAC to taxanes through GS-dependent and GS-independent mechanisms.

Leishmania presents a complex life cycle that involves both invertebrate and vertebrate hosts. By regulating gene expression, protein synthesis, and metabolism, the parasite can adapt to various environmental conditions. This regulation occurs mainly at the post-transcriptional level and may involve epitranscriptomic modifications of RNAs.

Diabetes is a chronic metabolic disease that is endemic worldwide and is characterized by persistent hyperglycemia accompanied by multiple severe complications, including cardiovascular disease, kidney dysfunction, neuropathy, and retinopathy. The pathogenesis of diabetes mellitus and its complications is multifactorial, involving various molecular and cellular pathways. In recent years, research has indicated that mechanisms of cell death play a significant role in the advancement of diabetes and its complications.

The hydraulic column is a core component in the coal mine support system, however, the real-time monitoring of the hydraulic column during the service process of the hydraulic support faces challenges. To address these issues, a high-precision stress mapping method of hydraulic column is proposed. The hydraulic column loss function was constructed to guide the data-driven model training, and the cylinder stress mechanism model was established by using the elastic-plastic theory of thick-walled cylinder.

Given the significant prevalence of adverse childhood experiences (ACEs) and their detrimental impact on mental health, this study examines the relationship between attachment anxiety, attachment avoidance, and complex post-traumatic stress disorder (CPTSD) among college students with ACEs, emphasizing the mediating role of self-compassion (SC). A sample of 32,388 students from Kunming, China completed a survey including the Revised Adverse Childhood Experiences Questionnaire (ACEQ-R), the Adult Attachment Scale (AAS), the International Trauma Questionnaire (ITQ), and the Self-Compassion Scale-Short Form (SCS-SF). Among the participants, 3,896 reported at least one ACE.
