Article Synopsis
  • The study compares two methods of endoscopic necrosectomy—percutaneous endoscopic necrosectomy (PEN) and endoscopic transmural necrosectomy (ETN)—for treating necrotizing pancreatitis (NP), focusing on their safety and efficacy.
  • A total of 280 adult NP patients were analyzed, revealing that while those who underwent PEN experienced higher rates of complications like sepsis and respiratory failure, there were no significant differences in overall outcomes, such as clinical success or postoperative complications, between the two methods.
  • The findings suggest that PEN may be a suitable option for managing sicker patients with NP, as it shows similar efficacy and safety compared to ETN in a real-world setting.

Lung cancer is a highly malignant disease, primarily due to its propensity for metastasis. AMP-activated protein kinase (AMPK), the principal downstream effector of Liver Kinase B1 (LKB1), orchestrates a broad spectrum of molecular targets, thereby constraining tumor invasion and metastasis. In parallel, the RNA-binding protein RBMS3 (RNA-binding motif, single-stranded-interacting protein 3) plays a pivotal role in the epithelial-mesenchymal transition (EMT), a pivotal process in tumorigenesis.

Article Synopsis
  • Paclitaxel (PTX) is a cancer drug whose effectiveness is often reduced by resistance, particularly due to low levels of the transporter SLCO1B3 which helps the drug enter cells.
  • Research has shown that activating AMP-activated protein kinase (AMPK) can increase SLCO1B3 levels and make tumor cells more sensitive to PTX.
  • Experiments indicated that using AMPK activators can improve SLCO1B3 expression and PTX efficacy in resistant A549 cells, suggesting strategies to overcome PTX resistance in cancer treatment.

B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1) is a core protein component of the polycomb repressive complex 1 that inhibits cell senescence and maintains the self-renewal ability of stem cells via downregulation of and expression. Bmi-1 serves an important role in hematopoietic stem cell maintenance and neurodevelopment during embryonic development, and it has been shown to enhance tumorigenesis by promoting cancer stem cell self-renewal and epithelial to mesenchymal transition. Emerging evidence suggests that overexpression is closely related to the development and progression of various types of cancer, and that downregulation of Bmi-1 expression can inhibit the proliferation, invasion and metastasis of cancer cells.

AMP-activated protein kinase (AMPK) is a conserved sensor of cellular energy change and is activated by increased AMP/ATP and/or ADP/ATP ratios. AMPK maintains the energy balance by decreasing the ATP-consuming processes such as transcription of synthetic fat genes and rRNA, the translation of ribosomal proteins, synthesis of cholesterol and fatty acid, while the metabolic pathways such as glucose and fatty transport, fatty acid oxidation, autophagy, mitochondrial synthesis and oxidative metabolism are increased to preserve ATP during energy deficiency. Recent advance has demonstrated that AMPK activity has a close association with the initiation and progression in various cancers.
