A supramolecular nanoprodrug for prevention of gallstone formation

Cholelithiasis affects approximately 10%-20% of the adult population globally. And cholesterol accumulation and nucleation of cholesterol crystals are commonly recognized as the primary process in the initiation and progression of gallstones. Hydroxypropyl-β-cyclodextrin(HPCD) is a supramolecular host compound that can solubilize cholesterol, potentially serving as a preventative or therapeutic agent for cholelithiasis. However, we found that the administration of HPCD treatment did not impede the formation of gallstones in mice, mainly attributed to the pre-complexation of its cavity during the transition process. Here we synthesized a prodrug of HPCD and prepared a HPCD nanoparticle(HPCD-NP), which can be transported efficiently to the gallbladder through the hepatobiliary system following an intravenous injection. In the bile, the HPCD-NP degraded into free HPCD, bound to cholesterol crystals and gallstones within the gallbladder and effectively increased cholesterol solubilization, leading to gallstones regression. Given the established safety of both HPCD and cyclodextrin-based nanoparticles in numerous animal and human studies, HPCD-NP shows considerable promise for the prevention and treatment of human cholelithiasis.

Objective: Neuroblastoma is the most common extracranial solid tumor in children and has complex genetic underpinnings. Previous genome-wide association studies(GWASs) have identified many loci associated with neuroblastoma susceptibility; however, their application in risk prediction for Chinese children has not been systematically explored. This study seeks to enhance neuroblastoma risk prediction by validating these loci and evaluating their performance in polygenic risk ***: We validated 35 GWAS-identified neuroblastoma susceptibility loci in a cohort of Chinese children,consisting of 402 neuroblastoma patients and 473 healthy controls. Genotyping these polymorphisms was conducted via the TaqMan method. Univariable and multivariable logistic regression analyses revealed the genetic loci significantly associated with neuroblastoma risk. We constructed polygenic risk models by combining these loci and assessed their predictive performance via area under the curve(AUC) analysis. We also established a polygenic risk scoring(PRS) model for risk prediction by adopting the PLINK ***: Fourteen loci, including ten protective polymorphisms from CASC15, BARD1, LMO1, HSD17B12, and HACE1, and four risk variants from BARD1, RSRC1, CPZ and MMP20 were significantly associated with neuroblastoma risk. Compared with single-gene model, the 8-gene model(AUC=0.72) and 13-gene model(AUC=0.73) demonstrated superior predictive performance. Additionally, a PRS incorporating six significant loci achieved an AUC of 0.66, effectively stratifying individuals into distinct risk categories regarding neuroblastoma susceptibility. A higher PRS was significantly associated with advanced International Neuroblastoma Staging System(INSS) stages, suggesting its potential for clinical risk ***: Our findings validate multiple loci as neuroblastoma risk factors in Chinese children and demonstrate the utility of polygenic risk models, particularly the PRS, in
