A forward genetic screen identifies potassium channel essentiality in SHH medulloblastoma maintenance.

Distinguishing tumor maintenance genes from initiation, progression, and passenger genes is critical for developing effective therapies. We employed a functional genomic approach using the Lazy Piggy transposon to identify tumor maintenance genes in vivo and applied this to sonic hedgehog (SHH) medulloblastoma (MB). Combining Lazy Piggy screening in mice and transcriptomic profiling of human MB, we identified the voltage-gated potassium channel KCNB2 as a candidate maintenance driver.

Risk of clinically significant prostate cancer undercategorized by multiparametric magnetic resonance imaging.

Background: To investigative potential clinicopathological characteristics and imaging-related risk factors of clinically significant prostate cancer (csPCa) undercategorized in patients with negative or equivocal MRI.

Methods: This retrospective study included 581 patients with pathologically confirmed csPCa (Gleason score ≥ 3 + 4), including 108 undercategorized csPCa and 473 detected csPCa. All patients underwent multiparametric MRI (mpMRI).

Quantitative Trait Loci Identification and Candidate Genes Characterization for Indole-3-Carbinol Content in Seedlings of .

is a member of the cruciferous family with rich glucosinolate (GSL) content, particularly glucobrassicin (3-indolylmethyl glucosinolate, I3M), that can be metabolized into indole-3-carbinol (I3C), a compound with promising anticancer properties. To unravel the genetic mechanism influencing I3C content in rapeseed seedlings, a comprehensive study was undertaken with a doubled haploid (DH) population. By quantitative trait loci (QTL) mapping, seven QTL that were located on A01, A07, and C04 were identified, with the most significant contribution to phenotypic variation observed on chromosome A07 (11.

Immunohistochemical Profiling of Histone Modification Biomarkers Identifies Subtype-Specific Epigenetic Signatures and Potential Drug Targets in Breast Cancer.

Breast cancer (BC) subtypes exhibit distinct epigenetic landscapes, with triple-negative breast cancer (TNBC) lacking effective targeted therapies. This study investigates histone biomarkers and therapeutic vulnerabilities across BC subtypes. The immunohistochemical profiling of >20 histone biomarkers, including histone modifications, modifiers, and oncohistone mutations, was conducted on a discovery cohort and a validation cohort of BC tissues, healthy controls, and cell line models.

Identification of Downregulated Gene in Parkinson's Disease Through Integrated Transcriptomic Analysis and Validation.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by dopaminergic neuron degeneration and α-synuclein (α-syn) aggregation. Lipid metabolism dysfunction may contribute to PD progression. This study aims to identify lipid metabolism-related genes (LMGs) associated with PD using an integrative transcriptomic analysis of microarray and single-cell RNA sequencing (scRNA-seq) datasets from patients with PD and healthy controls.
