Background: Bladder cancer (BCa) is one of the most prevalent malignancies globally. Previous study has reported the inhibitory effect of methyltransferase-like 14 (METTL14) on BCa tumorigenesis, but its role in the cell migration, invasion and epithelial-mesenchymal transition (EMT) in BCa remains unknown.
Materials And Methods: Quantitative real-time PCR (RT-qPCR) and western blot were applied to measure RNA and protein expression respectively. Cell migration, invasion and EMT were evaluated by wound healing, Transwell, and immunofluorescence (IF) assays as well as western blot of EMT-related proteins. In vivo experiments were performed to analyze metastasis of BCa. Mechanism investigation was also conducted to study METTL14-mediated regulation of BCa progression.
Results: METTL14 overexpression prohibits BCa cell migration, invasion in vitro and tumor metastasis in vivo. METTL14 stabilizes USP38 mRNA by inducing N6-methyladenosine (m6A) modification and enhances USP38 mRNA stability in YTHDF2-dependent manner. METTL14 represses BCa cell migration, invasion and EMT via USP38. Additionally, miR-3165 inhibits METTL14 expression to promote BCa progression.
Conclusions: Our study demonstrated that METTL14 suppresses BCa progression and forms a feedback loop with USP38. In addition, miR-3165 down-regulates METTL14 expression to promote BCa progression. The findings may provide novel insight into the underlying mechanism of METTL14 in BCa progression.

P2X7 receptor (P2X7R) plays a role in regulating tumor progression, but it is unclear whether P2X7R affects the pathological characteristics of patients with gastric cancer and the activity of gastric cancer cells. Therefore, this study preliminarily investigated the relationship between P2X7R and clinicopathological features of patients with gastric cancer, and further explored the effect of P2X7R on the proliferation, migration and invasion of gastric cancer cells through functional experiments. The results showed that P2X7R was highly expressed in gastric cancer tissues and gastric cancer cells.

High-temperature proton exchange membrane fuel cells (HT-PEMFCs) offer solutions to challenges intrinsic to low-temperature PEMFCs, such as complex water management, fuel inflexibility, and thermal integration. However, they are hindered by phosphoric acid (PA) leaching and catalyst migration, which destabilize the critical three-phase interface within the membrane electrode assembly (MEA). This study presents an innovative approach to enhance HT-PEMFC performance through membrane modification using picosecond laser scribing, which optimises the three-phase interface by forming a graphene-like structure that mitigates PA leaching.

Liver metastasis is the main cause of cancer-related mortality. During the metastasis process, circulating carcinoma cells hardly pass through narrow capillaries, leading to nuclear deformation. However, the effects of nuclear deformation and its underlying mechanisms on metastasis need further study.

Introduction: Antimicrobial resistance is a growing health problem. Pseudomonas aeruginosa is a pathogen of major concern because of its multidrug resistance and global threat, especially in health-care settings. The pathogenesis and drug resistance of depends on its ability to form biofilms, making infections chronic and untreatable as the biofilm protects against antibiotics and host immunity.

Hepatic fibrosis, a degenerative liver lesion, significantly contributes to the deterioration and mortality among patients with chronic liver diseases. The condition arises from various factors including toxins, such as alcohol, infections like different types of viral hepatitis, and metabolic diseases. Currently, there are no effective treatments available for liver fibrosis.
