Early detection and treatment of head and neck cancer has led to increased patient survival. However such patients are at a high risk for multiple primary neoplasm(s) (MPN). In order to study the genetic susceptibility to MPN, 22 candidate SNPs were genotyped based on which a distinctive Genotype Score was created using Additive, Dominant and Recessive models. Using lymphoblastoid cell lines (LCLs) generated from these individuals, the Genotype Score was correlated with carcinogen sensitivity in vitro. LCLs from MPN patients exhibited significantly higher Genotype Score and showed resistance to genotoxic agents compared to matched controls. This report demonstrates quantitative assessment of cumulative effect of gene polymorphisms and its correlation with carcinogen sensitivity for predicting susceptibility to MPN.

A chromosome-level, haplotype-resolved genome assembly and annotation for the Eurasian minnow (Leuciscidae: Phoxinus phoxinus) provide evidence of haplotype diversity.

Background: In this study, we present an in-depth analysis of the Eurasian minnow (Phoxinus phoxinus) genome, highlighting its genetic diversity, structural variations, and evolutionary adaptations. We generated an annotated haplotype-phased, chromosome-level genome assembly (2n = 50) by integrating high-fidelity (HiFi) long reads and chromosome conformation capture data (Hi-C).
Results: We achieved a haploid size of 940 megabase pairs (Mbp) for haplome 1 and 929 Mbp for haplome 2 with high scaffold N50 values of 36.

Apolipoprotein () genotype and nitric oxide (NO) deficiency are risk factors for age-associated cognitive decline. The oral microbiome plays a critical role in maintaining NO bioavailability during aging. The aim of this study was to assess interactions between the oral microbiome, NO biomarkers, and cognitive function in 60 participants with mild cognitive impairment (MCI) and 60 healthy controls using weighted gene co-occurrence network analysis and to compare the oral microbiomes between carriers and noncarriers in a subgroup of 35 MCI participants.

A large proportion of genetic variations involved in complex diseases are rare and located within noncoding regions, making the interpretation of underlying biological mechanisms a daunting task. Although technical and methodological progress has been made to annotate the genome, current disease-rare-variant association tests incorporating such annotations suffer from two major limitations. First, they are generally restricted to case-control designs of unrelated individuals, which often require tens or hundreds of thousands of individuals to achieve sufficient power.
