Article Abstract
Human embryonic (hES) stem cells are widely used as an in vitro model to understand global genetic and epigenetic changes that occur during early embryonic development. In-house derived hES cells (KIND1) were subjected to directed differentiation into cardiovascular progenitors (D12) and beating cardiomyocytes (D20). Transcriptome profiling of undifferentiated (D0) and differentiated (D12 and 20) cells was undertaken by microarray analysis. ChIP and sequential ChIP were employed to study role of transcription factor NR2F2 during hES cells differentiation. Microarray profiling showed that an alteration of about 1400 and 1900 transcripts occurred on D12 and D20 respectively compared to D0 whereas only 19 genes were altered between D12 and D20. This was found associated with corresponding expression pattern of chromatin remodelers, histone modifiers, miRNAs and lncRNAs marking the formation of progenitors and cardiomyocytes on D12 and D20 respectively. ChIP sequencing and sequential ChIP revealed the binding of NR2F2 with polycomb group member EZH2 and pluripotent factor OCT4 indicating its crucial involvement in cardiac differentiation. The study provides a detailed insight into genetic and epigenetic changes associated with hES cells differentiation into cardiac cells and a role for NR2F2 is deciphered for the first time to down-regulate OCT-4 via EZH2 during cardiac differentiation.

Hepatitis C virus (HCV) clearance markedly reduces the risk of hepatocellular carcinoma (HCC); however, HCC continues to develop in a subset of patients, particularly in those with advanced fibrosis or cirrhosis. Leading hepatology societies, including Asian Pacific Association for the Study of the Liver, European Association for the Study of the Liver, American Association for the Study of Liver Diseases, Korean Association for the Study of the Liver, Taiwan Association for the Study of the Liver, and Japan Society of Hepatology, have issued divergent guidelines for HCC surveillance after sustained virologic response, which reflects variations in regional patient populations, healthcare infrastructure, and policy priorities. While traditional risk stratification primarily centers on histological staging of fibrosis, an array of additional host-related factors, including age, sex, alcohol use, metabolic comorbidities, and genetic and epigenetic profiles, further influence individual HCC risks.

DNA, a large molecule located in the nucleus, carries essential genetic information, including gene loci and cis-regulatory elements. Despite its extensive length, DNA is compactly stored within the limited space of the nucleus due to its hierarchical three-dimensional (3D) organization. In this structure, DNA is organized into territories known as topologically associated domains (TADs).

Background: Epigenetic regulation significantly affects immune responses in lung adenocarcinoma (LUAD). However, the role of RNA N6-methyladenosine (m6A) modification, especially in obstructive sleep apnea-hypopnea syndrome (OSAHS) within LUAD, is not well understood.
Methods: This study examined m6A modification patterns in 973 LUAD patients using 23 regulatory genes.

Chromodomain helicase DNA binding protein 7 (CHD7), an ATP-dependent chromatin remodeler, plays versatile roles in neurodevelopment. However, the functional significance of its ATPase/nucleosome remodeling activity remains incompletely understood. Here, we generate genetically engineered mouse embryonic stem cell lines harboring either an inducible Chd7 knockout or an ATPase-deficient missense variant identified in individuals with CHD7-related disorders.

Epilepsy is a neurological disorder that shows strong genetic control on the timing and onset of symptoms and drug response variability. Some epilepsy syndromes have clear monogenic mutations but genes with control on the phenotype and severity of the disorder and drug sensitivity are present in the whole genetic profile. Genetic modifiers are not the cause of epilepsy but control significant networks such as synaptic plasticity and ion channels and neurodevelopment and neuroinflammation and therefore the reason why two individuals with the same primary mutations have different clinical courses.
