Objective: To investigate the allele and genotype frequencies of reduced folate carrier gene (RFC) 80G/A polymorphism in Chinese patients with acute leukemia (AL) and healthy control children, and to provide clue for association between the single nucleotide polymorphism (SNP) of RFC and the occurrence of AL.
Methods: Bone marrow samples from 98 childhood patients with AL and peripheral blood samples from 135 healthy children were obtained to prepare complementary DNAs (cDNAs). The cDNAs were analyzed for the polymorphisms in RFC 80G/A by reverse transcriptase-polymerase chain reaction-denaturing gradient gel electrophoresis (RT-PCR-DGGE) and direct sequencing.
Results: The A allele frequencies of the AL patients and control children were 0.515 and 0.415, respectively (P< 0.05). Chi-square test confirmed a statistical significance of the association between RFC80 G/A and AL.
Conclusion: RFC 80AA or GA genotype may contribute to increasing the susceptibility to AL.

Ecology and evolution are considered distinct processes that interact on contemporary time scales in microbiomes. Here, to observe these processes in a natural system, we collected a two-decade, 471-metagenome time series from Lake Mendota (Wisconsin, USA). We assembled 2,855 species-representative genomes and found that genomic change was common and frequent.

Purpose: Mesalazine and thiopurines are important therapeutic agents for pediatric patients with ulcerative colitis (UC). Mesalazine, which may be administered in different forms depending on delivery mechanisms, can affect thiopurine metabolism, leading to increased 6-thioguanine nucleotides (6-TGN) levels. Therefore, when using these two drugs simultaneously, their interactions must be considered.

Central obesity is associated with higher risk of developing a wide range of diseases independent of overall obesity. Genome-wide association studies (GWASs) have identified more than 300 susceptibility loci associated with central obesity. However, the functional understanding of these loci is limited by the fact that most loci are in non-coding regions.

This review addresses the significant advancements in the identification of blood-based prognostic biomarkers for tuberculosis (TB), highlighting the importance of early detection to prevent disease progression. The manuscript discusses various biomarker categories, including transcriptomic, proteomic, metabolomic, immune cell-based, cytokine-based, and antibody response-based markers, emphasizing their potential in predicting TB incidence. Despite promising results, practical application is hindered by high costs, technical complexities, and the need for extensive validation across diverse populations.

Genetic polymorphism can cause variation in tramadol (TR) pharmacokinetic characteristics and the expected clinical response. In forensic toxicology, the data about parent and metabolite concentrations (MRs; metabolic ratios) could facilitate to determine the cause of death and to assess time between drug intake and death. In this study, the aim was to investigate if UGT1A8, UGT2B7, ABCC2, and SLC22A1 genotyping can facilitate interpretation by investigating the frequency of UGT1A8, UGT2B7, ABCC2, and SLC22A1 genotypes in forensic autopsy cases positive for TR and to assess whether there is a correlation between these genetic variants and MRs.
