Gut virome dysbiosis impairs antitumor immunity and reduces 5-fluorouracil treatment efficacy for colorectal cancer.

Introduction: Despite the established influence of gut bacteria, the role of the gut virome in modulating colorectal cancer (CRC) patient chemotherapy response remains poorly understood. In this study, we investigated the impact of antiviral (AV) drug-induced gut virome dysbiosis on the efficacy of 5-FU in CRC treatment.

Effect of Cytoskeletal Linker Protein GAS2L1 on Oligodendrocyte and Myelin Development.

Oligodendrocytes (OLs), the myelin-forming cells of the central nervous system (CNS), develop from OL precursor cells (OPCs) through a complex process involving significant morphological changes that are critically dependent on the dynamic interactions between cytoskeletal networks. Growth arrest-specific 2-like protein 1 (GAS2L1) is a cytoskeletal linker protein that mediates the cross-talk between actin filaments and microtubules. However, its role in OL and myelin development remains unknown.

Random forest predictive modeling of prolonged hospital length of stay in elderly hip fracture patients.

Background: In elderly individuals suffering from hip fractures, a prolonged hospital length of stay (PLOS) not only heightens the probability of patient complications but also amplifies mortality risks. Yet, most elderly hip fracture patients present compromised baseline health conditions. Additionally, PLOS leads to increased expenses for patient treatment and care, while also diminishing hospital turnover rates.

Targeted PLK1 suppression through RNA interference mediated by high-fidelity Cas13d mitigates osteosarcoma progression via TGF-β/Smad3 signalling.

Defensins regulate cell cycle: Insights of defensins on cellular proliferation and division.

Defensins are a class of small antimicrobial peptides that play a crucial role against pathogens. However, recent research has highlighted defensins exhibit the ability to influence cell cycle checkpoints, promoting or inhibiting specific phases such as G1 arrest or S/M transition. By regulating the cell cycle, defensins impact the proliferation of normal and cancerous cells, with implications for cancer development and progression.

Recent advances in metal-organic frameworks for stimuli-responsive drug delivery.

After entering the human body, drugs for treating diseases, which are prone to delivery and release in an uncontrolled manner, are affected by various factors. Based on this, many researchers utilize various microenvironmental changes encountered during drug delivery to trigger drug release and have proposed stimuli-responsive drug delivery systems. In recent years, metal-organic frameworks (MOFs) have become promising stimuli-responsive agents to release the loaded therapeutic agents at the target site to achieve more precise drug delivery due to their high drug loading, excellent biocompatibility, and high stimuli-responsiveness.
