The p53 protein acts as a checkpoint in the cell cycle, either preventing or initiating apoptosis. Since cancer is the unchecked proliferation of cells, p53s role is critical. Thus, we have sought a link between the p53 polymorphisms and apoptosis. Wild-type p53 tumor suppressor gene exhibits several common single nucleotide polymorphisms (SNP) both in coding and non-coding regions. We focused on two of them, the p53 BstUI SNP on the fourth exon, and the p53 MspI SNP on the sixth intron. We investigated a presence of these two polymorphisms in relation to apoptosis of white blood cells in lung cancer patients and healthy controls. We found that both the p53 BstUI and the p53 MspI homozygous genotypes A2/A2 were associated with significantly higher content of apoptotic white blood cells in comparison to relevant A2/A1 heterozygous genotypes (P<0.001,0.05) in lung cancer patients. These observations suggest that the p53 BstUI and the p53 MspI SNPs may play a certain role in p53 dependent apoptotic pathway.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a primary cause of chronic liver disease, with potential progression to cirrhosis and hepatocellular carcinoma (HCC). Although systemic inflammatory biomarkers are associated with liver diseases, their specific role in MASLD remains unclear. This study examines the association between systemic inflammatory biomarkers and MASLD.

ETV6::RUNX1 is the most common fusion gene in childhood acute lymphoblastic leukemia (ALL) associated with favorable prognosis, but the optimal therapy for this subtype remains unclear. Profiling the genomic and pharmacological landscape of 194 pediatric ETV6::RUNX1 ALL cases, we uncover two transcriptomic clusters, C1 (61%) and C2 (39%). Compared to C1, the C2 subtype features higher white blood cell counts and younger age at diagnosis, as well as better early treatment responses.

Background And Objectives: Cognitive deficits represent a major long-term complication of anti-leucine-rich, glioma-inactivated 1 encephalitis (LGI1-E). Although severely affecting patient outcomes, the structural brain changes underlying these deficits remain poorly understood. In this study, we hypothesized a link between white matter (WM) networks and cognitive outcomes in LGI1-E.

Background: The impact of iron deficiency on COPD morbidity independent of anemia status is unknown. Understanding the association between iron deficiency, anemia status, and risk of hospitalization in COPD may inform an approach to these comorbidities.
Study Design And Methods: Adults ≥40 years from the Johns Hopkins COPD Precision Medicine Center of Excellence data repository with an outpatient iron profile and 1 year of subsequent follow-up time were included in the study.
