Nitazenes are a class of synthetic opioids that have recently emerged in the illegal drug market. They are characterized by high potency and a narrow therapeutic window. Compared with traditional opioids, these substances are more likely to cause severe respiratory depression.

Cyclin-dependent kinase 5 regulatory subunit-associated protein 3 (CDK5RAP3) is a newly identified super-enhancer-driven gene regulated by master TFs in NB; however, its function in NB remains unclear. Through an integrated study of publicly available datasets and microarrays, we observed a significantly elevated CDK5RAP3 expression level in NB, associated with poor patient prognosis.

Malignant cells in PNTs are theorized to interconvert between adrenergic/noradrenergic and mesenchymal/neural crest cell states. Here, single-cell RNA-sequencing analysis of 10 PNTs demonstrates extensive transcriptomic heterogeneity.

Purpose: The study aims to access the value of B-cell lymphoma/leukemia 11A (BCL11A) in the prognosis of patients with neuroblastoma (NB) and to explore its role and possible mechanism in NB.
Methods: Tumor specimens from 53 children with neuroblastoma were evaluated for the relationship between BCL11A expression level and prognosis of NB patients. Online datasets like SEQC and Asgharzadeh were analyzed to further check out the suppose.
Neuroblastoma (NB) is one of the most common extracranial malignant solid tumors in childhood, and over 90% of NBs are diagnosed in children under the age of 10 years old. For patients between 14 and 18 years old or older than 18 years, due to the rarity of NB, few studies have been performed in this population. Defined "adolescent cases" as individuals in 14-18 years old and "adult cases" as older than 18 years old, we reported five NB cases of adolescents and adults in our hospital.
