Differences in expression of drug response-related genes contribute to inter-individual variation in drugs' biological effects. MicroRNAs (miRNAs) are small noncoding RNAs emerging as new players in epigenetic regulation of gene expression at post-transcriptional level. MiRNAs regulate the expression of genes involved in drug metabolism, drug transportation, drug targets and downstream signal molecules directly or indirectly. MiRNA polymorphisms, the genetic variations affecting miRNA expression and/or miRNA-mRNA interaction, provide a new insight into the understanding of inter-individual difference in drug response. Here, we provide an overview of the recent progress in miRNAs mediated regulation of biotransformation enzymes, drug transporters, and nuclear receptors. We also describe the implications of miRNA polymorphisms in cancer chemotherapy response.

Type 2 diabetes mellitus (T2DM) and cardiogenic stroke (CS) are harmful to human health. Previous studies have shown a correlation between T2DM and CS, but the causal relationships and pathogenic mechanisms between T2DM and CS remain unclear. We downloaded T2DM and CS datasets from a genome-wide Association Study and performed Mendelian randomization (MR) analysis using the TwoSampleMR package in R software.

Background: In 2019, the Open Pediatric Brain Tumor Atlas (OpenPBTA) was created as a global, collaborative open-science initiative to genomically characterize 1,074 pediatric brain tumors and 22 patient-derived cell lines. Here, we present an extension of the OpenPBTA called the Open Pediatric Cancer (OpenPedCan) Project, a harmonized open-source multiomic dataset from 6,112 pediatric cancer patients with 7,096 tumor events across more than 100 histologies. Combined with RNA sequencing (RNA-seq) from the Genotype-Tissue Expression and The Cancer Genome Atlas projects, OpenPedCan contains nearly 48,000 total biospecimens (24,002 tumor and 23,893 normal specimens).

Variation in response to clopidogrel represents a significant clinical challenge in patients with ischemic stroke. Genetic polymorphisms cytochrome P450 2C19 (CYP2C19) are a known cause of resistance to clopidogrel. Platelet microRNAs (miRNAs) can modulate the efficacy of antiplatelet therapy.

: Acute lymphoblastic leukemia (ALL) is the most common childhood cancer, accounting for 80% of leukemias in this group and about 25% of all cancers. The 5-year survival rate is now over 90%. Achieving such a good outcome is made possible by the introduction of intensive, high-dose chemotherapy.

Background: Inflammasomes regulate the activation of caspases resulting in inflammation; inflammasome activation is dysregulated in Alzheimer's disease (AD) and plays a role in the pathogenesis of this condition. Glibenclamide, an anti-inflammatory drug, could be an interesting way to down-modulate neuroinflammation.
Methods: In this pilot study we verified with ex vivo experiments whether a glibenclamide-loaded nanovector (GNV) could reduce the NLRP3-inflammasome cascade in cells of AD patients.
