Dexmedetomidine protects against sepsis-induced lung injury through autophagy and Smad2/3 signaling pathway.

Objectives: Dexmedetomidine (Dex) is a potent α2-adrenergic receptor(α2-AR) agonist that has been shown to protect against sepsis-induced lung injury, however, the underlying mechanisms of this protection are not fully understood. Autophagy and the Smad2/3 signaling pathway play important roles in sepsis-induced lung injury, but the relationship between Dex and Smad2/3 is not clear. This study aimed to investigate the role of autophagy and the Smad2/3 signaling pathway in Dex-mediated treatment of sepsis-induced lung injury.

Multifunctional Mesoporous Silica-Coated Gold Nanorods Mediate Mild Photothermal Heating-Enhanced Gene/Immunotherapy for Colorectal Cancer.

Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading cause of cancer-related deaths in the world. It is urgent to search for safe and effective therapies to address the CRC crisis. The siRNA-based RNA interference targeted silencing of PD-L1 has extensive potential in CRC treatment but is limited by the lack of efficient delivery vectors.

Xanthine oxidase, a therapeutic target of realgar for non-small cell lung cancer.

Background: The effects of realgar against non-small cell lung cancer (NSCLC) have been massively studied, but the direct therapeutic targets of realgar remain unclear. This study aimed to identify the molecular targets of realgar against NSCLC and explore their therapeutic mechanisms based on a network pharmacology approach and experimental validations.

Methods: The BATMAN-TCM and Digsee databases were used to predict realgar targets and NSCLC-related genes, respectively.

Effects of macrophages on the proliferation and cardiac differentiation of human induced pluripotent stem cells.

Background: Macrophage phenotypes switch from proinflammatory (M1) to anti-inflammatory (M2) following myocardial injury. Implanted stem cells (e.g.

Prodrug-Loaded Zirconium Carbide Nanosheets as a Novel Biophotonic Nanoplatform for Effective Treatment of Cancer.

Conventional chemotherapy and photothermal therapy (PTT) face many major challenges, including systemic toxicity, low bioavailability, ineffective tissue penetration, chemotherapy/hyperthermia-induced inflammation, and tumor angiogenesis. A versatile nanomedicine offers an exciting opportunity to circumvent the abovementioned limitations for their successful translation into clinical practice. Here, a promising biophotonic nanoplatform is developed based on the zirconium carbide (ZrC) nanosheet as a deep PTT-photosensitizer and on-demand designed anticancer prodrug SN38-Nif, which is released and activated by photothermia and tumor-overexpressed esterase.

Effect of TW37 on the growth of H1975 EGFR‑TKI‑resistant lung cancer cells and its underlying mechanisms.

Previous studies have suggested that the B‑cell lymphoma 2 (Bcl‑2) inhibitor, TW37, may induce apoptosis of the non‑small cell lung cancer cell line, H1975/epidermal growth factor receptor‑tyrosine kinase inhibitor (EGFR‑TKI), which exhibits secondary resistance to EGFR‑TKI. However, the effects of TW37 on H1975/EGFR‑TKI cells remain unclear. The aim of the present study was to investigate the effects of TW37 on the growth of H1975/EGFR‑TKI cells and explore the underlying mechanisms.
