Serum 25-hydroxyvitamin D levels and peripheral blood eosinophil percentages as predictive indicators for eosinophilic chronic sinusitis with nasal polyps.

Purpose: Chronic rhinosinusitis (CRS) has a high incidence rate and different endotypes. Serum 25-hydroxyvitamin D (25(OH)D) deficiency is common in patients with eosinophilic and non-eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP and nECRSwNP, respectively). This study explored the relationship between serum 25(OH)D levels and CRS risk and determined the value of combining serum 25(OH)D with peripheral blood markers in distinguishing between ECRSwNP and nECRSwNP.

Vitamin D impedes eosinophil chemotaxis via inhibiting glycolysis-induced CCL26 expression in eosinophilic chronic rhinosinusitis with nasal polyps.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is likely to relapse due to aberrant eosinophil infiltration. The deficiency of Vitamin D (VD) is associated with increased eosinophil infiltration in eosinophilic oesophagitis. However, the role of VD in eosinophilic CRSwNP (ECRSwNP) remains unclear.

LRG1-Targeted Camptothecin Nanomicelles with Simultaneous Delivery of Olaparib for Enhanced Colorectal Cancer Chemotherapy.

Camptothecin (CPT), an effective topoisomerase I inhibitor used in colorectal cancer chemotherapy, often faces limitations due to severe toxicities. Addressing this, we developed OCE, a nanomedicine featuring the CPT-ET conjugate─comprising a cathepsin B-sensitive linker and CPT linked to the ET peptide targeting leucine-rich alpha-2-glycoprotein 1 (LRG1) and encapsulating Olaparib, a potent poly ADP-ribose polymerase (PARP) inhibitor. OCE aims for precise CPT delivery to colorectal cancer sites overexpressing LRG1, while Olaparib disrupts compromised DNA repair pathways, enhancing DNA damage and promoting increased tumor cell apoptosis.

Targeted degradation of LRG1 to attenuate renal fibrosis.

Leucine-rich α-2 glycoprotein 1 (LRG1), a secreted glycoprotein, has been identified as significantly upregulated in renal fibrosis, potentially exacerbating the condition by enhancing TGF-β-Smad3-dependent signaling pathways. Herein, utilizing our developed LRG1-targeting peptide for LRG1 recruitment and lenalidomide for E3 ubiquitin ligase engagement, we developed an advanced proteolysis targeting chimera, TAC-2, specifically designed for LRG1 degradation. Our cellular degradation assays validated that TAC-2 effectively degraded LRG1 through a proteasome-dependent mechanism, achieving half-maximal degradation at a concentration of 8.

LRG1-Targeted Nintedanib Delivery for Enhanced Renal Fibrosis Mitigation.

Renal fibrosis lacks effective nephroprotective drugs in clinical settings due to poor accumulation of therapeutic agents in damaged kidneys, underscoring the urgent need for advanced renal-targeted delivery systems. Herein, we exploited the significantly increased expression of the leucine-rich α-2 glycoprotein 1 (LRG1) protein during renal fibrosis to develop a novel drug delivery system. Our engineered nanocarrier, DEN, preferentially targets fibrotic kidneys via the decorated ET peptide's high affinity for LRG1.
