Summary: Dual antimicrobial materials with antimicrobial and antifouling properties were developed by modifying PVC catheters with 4-vinyl pyridine (4VP) and subsequent functionalization with 1,3-propane sultone (PS) using gamma radiation. The materials were characterized and evaluated for their surface characteristics and performance in delivering ciprofloxacin, inhibiting bacterial growth, decreasing bacterial and protein adhesion, and stimulating cell growth. These materials have potential applications in manufacturing antimicrobial medical devices, providing localized antibiotic delivery systems for prophylaxis and infection treatment.

Summary: This study identifies the inositol 5-phosphatase INPP5B as a key regulator of actin remodeling, BCR clustering, and downstream signaling in antigen-stimulated B cells. INPP5B acts by dephosphorylating PI(4,5)P-2, which is necessary for actin disassembly, BCR mobilization, and cell spreading. INPP5B may represent a potential target for the treatment of B cell malignancies caused by aberrant BCR signaling.

Summary: The dynamics of cellular mechanisms can be studied through network analysis. Logic-based models are a popular and simple modeling strategy, but their simulation complexity grows exponentially instead of linearly with the number of nodes. This study applies logic modeling to quantum computing to simulate cellular networks and demonstrates the benefits, such as complexity reduction and quantum algorithms for systems biology tasks. A model of mammalian cortical development is implemented to showcase the applicability of this approach, and results from quantum processing units and a noisy simulator are presented, along with discussions on current technical challenges.

Summary: Mutations in various genes can cause the childhood disorder TTD, which is classified as a DNA repair disease or a transcription syndrome. Knockout/knockdown of TTDN1 and RNF113A resulted in consistent effects on ribosomal biogenesis and performance. Interference with these TTD factors led to downregulation of RNA polymerase I transcription, disrupted rRNA processing, reduced rRNA 18S backbone, impaired protein translation decoding, and accumulation of misfolded and carbonylated proteins, suggesting loss of protein homeostasis. This study proposes that ribosomal dysfunction is a common underlying mechanism in TTD.

Summary: In this study, the researchers explored the role of DHX38 in NSCLC and its underlying molecular mechanism. They found that DHX38 was overexpressed in NSCLC and patients with high DHX38 expression had poor prognosis. DHX38 promoted cell proliferation, migration, and invasion in NSCLC and activated the MAPK pathway. The researchers also identified G3BP1 as a target protein that interacted with DHX38 and showed that DHX38 regulated the expression of G3BP1. Silencing G3BP1 reversed the effects of DHX38 overexpression on tumor cell proliferation, migration, and invasion and inhibited the MAPK pathway activation.

Summary: Microenvironment signals have a significant impact on cell fate and tissue homeostasis. Understanding how different microenvironment factors regulate cellular phenotype has been challenging. In this study, a high-throughput microenvironment microarray was used to identify factors that support the proliferation and maintenance of primary human mammary luminal epithelial cells. Multiple factors that modulate luminal cell number were identified and their effects were confirmed using RNA sequencing and cell-based functional studies. Hepatocyte growth factor (HGF) was found to be robust to individual variation and played a role in expanding luminal cells. Our approach demonstrates the power of high-dimensional cell-based approaches in dissecting microenvironmental signals.

Summary: This study investigated the role of transcription factor FoxO1 in facet joint osteoarthritis (FJOA) and found that FoxO1 deletion led to severe osteoarthritic changes. Transcriptome sequencing and bioinformatics analysis identified differentially expressed genes (DEGs) and potential key contributors to FJOA. Additionally, over-expression of certain genes and inhibition of others were shown to counteract the impairments caused by FoxO1 deletion in chondrocyte migration and extracellular matrix synthesis. These findings help unravel the molecular mechanisms underlying FJOA and open up promising therapeutic avenues for its treatment.

Summary: Cholesterol biosynthesis and metabolism play critical roles in tumor development and microenvironmental conditions. Squalene Epoxidase (SQLE), the second rate-limiting enzyme in cholesterol synthesis, is found to be uniquely expressed in various cancers, and its expression level is closely associated with tumor mutation burden and microsatellite instability. SQLE expression is negatively correlated with immune cell infiltration. Inhibition of SQLE alters the immune response in the tumor microenvironment. Furthermore, protein metabolism and translation are identified as main binding factors with SQLE.

Summary: Circular RNAs (circRNAs) are non-coding RNAs that play a role in the regulation of various cancers, including osteosarcoma (OS). This study identified circSATB2 as a highly expressed circRNA in OS tissues and cell lines, and demonstrated its involvement in promoting OS proliferation and migration. Mechanistically, circSATB2 was found to regulate the progression of OS by sponging miR-661 and FUS to regulate ZNFX1 mRNA. These findings suggest that circSATB2 could serve as a prognostic marker and therapeutic target for osteosarcoma.

Summary: This study found that extracellular vesicles released by induced pluripotent stem cells can reduce inflammatory cell infiltration, increase saliva volume, and decrease the production of antibodies associated with Sjogren's syndrome in a mouse model. The let-7 family in these vesicles may suppress the expression of TLR4 and NF-kappa B, which leads to the inhibition of pro-inflammatory cytokine production through the MAPK pathway.

Summary: Recent evidence suggests that cAMP signaling within the primary cilium plays a crucial role in promoting adipogenic differentiation of 3T3-L1 preadipocytes. In this study, the researchers identified the specific cAMP phosphodiesterases expressed by these cells and found that inhibition of PDE4 promotes FFAR4-mediated adipogenesis. This work could potentially lead to the discovery of more targeted therapeutic approaches for controlling adipogenesis and differentiation of other stem cells.
