Objective: To investigate the genetic polymorphisms of DXS7132, DXS6854, DXS6797, DXS9898, DXS8378 and GATA31E08 short tandem repeats (STRs) loci in Chinese Korean ethnic group of Yanbian, Jilin, and to construct a preliminary database.
Methods: The allele frequencies of the six STRs loci in Chinese Korean ethnic individuals were analyzed by multiplex polymerase chain reaction (PCR) and polyacrylamide gel electrophoresis (PAGE).
Results: Total of 8, 6, 8, 8, 5 and 10 alleles were observed in each locus respectively. All loci (in female) met Hardy-Weinberg equilibrium (P > 0.05). The statistical analysis of the 6 STR loci showed the heterozygosities were more than 0.4660, the polymorphic information contents (PIC) were more than 0.5293, the haplotype diversity were more than 0.9993, power of discrimination (PD) in females and males were more than 0.7737 and 0.6107, respectively.
Conclusion: The results showed that, all the 6 STR loci in this study were found to have high heterozygosity and polymorphic information content, so they could provide useful markers for genetic purposes. These results could serve as valuable data to enrich the Chinese Korean ethnic group genetic database and play an important role in genetic study of Chinese population.

Interstitial lung disease (ILD) has shown limited treatment advancements, with minimal exploration of circulating protein biomarkers causally linked to ILD and its subtypes beyond idiopathic pulmonary fibrosis (IPF). In this study, we aimed to identify potential drug targets and circulating protein biomarkers for ILD and its subtypes. We utilized the most recent large-scale plasma protein quantitative trait loci (pQTL) data detected from the antibody-based method and ILD and its subtypes' GWAS data from the updated FinnGen database for Mendelian randomization analysis.

Genome-wide association studies (GWASs) have identified numerous genetic variants associated with complex traits, yet the biological interpretation remains challenging, especially for variants in non-coding regions. Expression quantitative trait locus (eQTL) studies have linked these variations to gene expression, aiding in identifying genes involved in disease mechanisms. Traditional eQTL analyses using bulk RNA sequencing (bulk RNA-seq) provide tissue-level insights but suffer from signal loss and distortion due to unaddressed cellular heterogeneity.

Background: The resistance of pancreatic ductal adenocarcinoma (PDAC) to trametinib therapy limits its clinical use. However, the molecular mechanisms underlying trametinib resistance in PDAC remain unclear.
Objective: We aimed to illustrate the mechanisms of resistance to trametinib in PDAC and identify trametinib resistance-associated druggable targets, thus improving the treatment efficacy of trametinib-resistant PDAC.

Background: Modern sedentary lifestyles are prevalent among individuals with osteoarthritis. However, direct evidence linking such behaviours as causative factors of osteoarthritis remain limited due to the presence of confounding variables.
Objective: This study aims to determine the extent to which lifestyle factors have causal effects on osteoarthritis through a two-sample Mendelian randomisation (MR) study.

Engineering nitrogen fixation in cereals could reduce usage of chemical nitrogen fertilizers. Here, a nitrogenase biosynthesis pathway comprising 13 genes (nifB nifH nifD nifK nifE nifN nifX hesA nifV nifS nifU groES groEL) was introduced into rice by transforming multigene vectors and subsequently by sexual crossing between transgenic rice plants. Genome sequencing analysis revealed that 13 nif genes in F hybrid rice lines L12-13 and L8-17 were inserted at two loci on rice chromosome 1.
