The histone lactylation of AIM2 influences the suppression of ferroptosis by ACSL4 through STAT5B and promotes the progression of lung cancer.

Lung cancer progression is characterized by intricate epigenetic changes that impact critical metabolic processes and cell death pathways. In this study, we investigate the role of histone lactylation at the AIM2 locus and its downstream effects on ferroptosis regulation and lung cancer progression. We utilized a combination of biochemical assays, including chromatin immunoprecipitation (ChIP), quantitative real-time PCR (qRT-PCR), and western blotting to assess histone lactylation levels and gene expression.

Aims: A cardiovascular magnetic resonance (CMR) approach to non-invasively estimate left ventricular (LV) filling pressure was recently developed and shown to correlate with invasively measured pulmonary capillary wedge pressure (PCWP). We examined the association between CMR-estimated PCWP (CMR-PCWP) and other imaging and biomarker measures of congestion, and the effect of empagliflozin on these, in the SUGAR-DM-HF trial (NCT03485092).
Methods And Results: SUGAR-DM-HF enrolled 105 patients with heart failure with reduced ejection fraction (HFrEF) and pre-diabetes or type 2 diabetes who were randomly assigned to empagliflozin 10 mg or placebo once daily for 36 weeks.
Transthyretin amyloid cardiomyopathy: a paradigm for advancing precision medicine.

Development of specific therapies addressing the underlying diseases' mechanisms constitutes the basis of precision medicine. Transthyretin cardiac amyloidosis (ATTR-CM) is an exemplar of precise therapeutic approach in the field of heart failure and cardiomyopathies. A better understanding of the underlying pathophysiology, more precise data of its epidemiology, and advances in imaging techniques that allow non-invasive diagnosis have fostered the development of new and very effective specific therapies for ATTR-CM.

Antibiotic tolerance presents a significant challenge in eradicating bacterial infections, as tolerant strains can survive antibiotic treatment, contributing to the recurrence of infections and the development of resistance. However, unlike antibiotic resistance, tolerance is not detectable by standard susceptibility assays such as minimal inhibitory concentration (MIC) tests. Consequently, antibiotic tolerance often goes unnoticed in clinical settings.

As the population of adults with congenital heart disease (ACHD) grows, there also grows an expanded need for non-invasive surveillance methods to guide management and intervention. A multimodal imaging approach layers complementary insights from echocardiography, computed tomography (CT), magnetic resonance imaging (MRI), and other modalities into a clinician's view of patient physiology. Merely applying strategies from acquired adult cardiac disease would be inadequate and potentially misleading.
