Summary: This study aimed to identify potential quantitative trait loci (QTL) for 27 production, fitness, and conformation traits of Guernsey cattle through genome-wide association analyses, with a major QTL detected on BTA19 and the MYH10 gene within this region highly associated with milk production and body conformation traits. After fine mapping, only one significant SNP was found on BTA19 for most traits, with multiple independent significant SNPs identified for protein yield, dairy form, and stature. The haplotype hosting the major QTL on BTA19 was traced back to a US Guernsey born in 1954, indicating a long-term influence on the population.

Summary: This study investigated the epigenetic and genetic regulation of the oxytocin receptor, dopamine transporter, and serotonin transporter genes in relation to Internet addiction. The results showed significant changes in DNA methylation levels and their correlation with psychometric properties. These findings contribute to our understanding of the neurobiology of Internet addiction and offer potential biological predictors for early diagnosis and treatment.

Summary: This study investigated the genetic mapping of plant architecture, flowering time, and maturity traits in cotton, and identified a total of 27 QTLs associated with these traits. The findings suggest that this population structure can help reduce background noise and small effect QTLs, and the germplasm developed in this study may serve as potential pre-breeding material for improving cotton cultivars.

Summary: This study aimed to analyze natural tail length variation in Merinolandschaf and identify causal alleles for the short tail phenotype segregating within long-tailed breeds. The research discovered a SNP in the first exon of HOXB13 and a SINE element in the promoter of HOXB13 as potential candidates. These findings have implications for breeding shorter-tailed sheep, improving animal welfare, and understanding differential embryonic development.

Summary: This study conducted a large-scale field trial on the progeny of Salix suchowensis and analyzed the genetic factors underlying plant growth. The results showed that stem height and ground diameter were controlled by four quantitative trait loci, with two of them exerting a pleiotropic effect. The pleiotropic effect was found to result from the co-localization of genes with independent effects on stem height and ground diameter. Furthermore, the study revealed that height and circumference growth involve different tissue activities.

Summary: The technique of single-cell RNA-sequencing has allowed researchers to explore the cellular heterogeneity of complex tissues. In this study, a scalable framework called scPI was proposed to analyze scRNA-seq data. The scPI framework utilizes amortized variational inference and a nonlinear neural network to infer the low-dimensional representations of the data. Through analysis of real datasets, it was demonstrated that scPI can effectively handle various probabilistic models for scRNA-seq data in terms of scalability, missing value imputation, and cell type clustering.

Summary: This study identified 13 rare high-risk loci for breast cancer, which exhibit significant risk increase when combined as haplotypes. The individual variants forming these rare haplotypes have smaller effects. Functional annotation revealed extensive cis-regulatory DNA elements in breast cancer-related cells underlying these replicated rare haplotypes.

Summary: This study investigated the impact of genetic risk for substance use disorders (SUDs) on the onset and progression of substance use. The results showed that European-ancestry individuals and males had an earlier onset and quicker progression of substance use, and the polygenic risk scores (PRSs) had predictive value for substance use milestones and symptom progression. In African-ancestry individuals, PRSs also predicted some substance use milestones, albeit to a lesser extent due to a smaller discovery sample.

Summary: This study used multi-trait analysis to identify novel loci associated with substance use disorders in European and African populations. The results showed that multi-trait analysis can improve the genetic modeling of substance use traits and uncover genes that were not previously linked to substance use.

Summary: This study investigated the effects of topiramate, a medication used to treat alcohol use disorder, on serum bicarbonate concentrations. The study found that the effects of the medication on bicarbonate concentrations were similar regardless of the presence of alcohol use disorder or the dosage of topiramate. Therefore, it is recommended to monitor baseline and periodic serum bicarbonate concentrations during topiramate therapy.

Summary: Chronic heavy alcohol use has negative impacts on neurotransmitter systems and causes various medical, psychiatric, and social problems. Evidence-based medications for treating alcohol use disorder (AUD) are not widely used in clinical practice. Pharmacogenetic approaches have gained interest but have not yet yielded strong enough results for routine clinical care.

Summary: Cocaine administration alters miRNA expression in the cortico-accumbal pathway, potentially impacting gene expression regulation during withdrawal. This study examined miRNA changes in this pathway during acute withdrawal and protracted abstinence from escalated cocaine intake. Results showed differential miRNA expression and pathways enriched in mRNA targets associated with addiction. The findings emphasize the importance of miRNA expression in addiction-related circuits and suggest the potential for developing biomarkers and therapies targeting abstinence-associated miRNAs.

Summary: Opioid use disorder (OUD) is a chronic condition with serious adverse consequences, including high incarceration rates and overdose-related fatalities. Medications used for OUD treatment have been shown to cause metabolic impairments, but the effects vary depending on the individual's metabolic condition. Further research is needed to determine the best approach for reducing the risk of metabolic disorders in OUD treatment.

Summary: This study found that common variants are associated with small but significant differences in breast cancer risk, supporting the polygenic model of inherited predisposition. Using a novel algorithm, the researchers showed that rare haplotypes may refine the association of breast cancer risk with common germline alleles. These findings provide insight into the genetic risk factors for breast cancer.

Summary: The findings from genome-wide association studies have greatly helped us understand the genetic basis of human complex traits and diseases. However, several major challenges still need to be addressed, including the unknown biological functions of most GWAS hits and the identification of genetic risk variants with weak effects. To overcome these challenges, we propose a powerful and adaptive latent model (PALM) that integrates functional annotations with GWAS summary statistics.
