Summary: The field of epigenetics has gained attention in cardiovascular research due to its association with disease development. Multi-omics approaches that integrate different levels of disease regulation, such as DNA, histone, and RNA modifications, are essential for understanding complex diseases like cardiovascular diseases. This review focuses on discussing the role of epigenetic mechanisms in regulating gene expression and their interlinkage in the development of cardiac disease, particularly heart failure. The review also presents current methods and tools used for data integration and analysis, which can contribute to the discovery of novel therapeutic approaches and biomarkers for precision healthcare and improved clinical outcomes.

Summary: As sessile organisms, plants acclimate or adapt to unfavorable conditions in order to survive. Flower induction regulation is crucial for reproduction and species survival. The effects of ionising radiation on flowering, including gene pathways and epigenetics, need to be studied for environmental radiation protection.

Summary: This study introduces two related non-negative measures of tripartite entanglement and shows that states with nonzero measures have nontrivial entanglement. Additionally, it demonstrates that these entanglement measures in one dimension depend only on the emergent low-energy theory. For a gapped system, it argues that entanglement measures either both nonzero or both zero, depending on the system's ground state. Furthermore, a numerical algorithm is developed for computing entanglement measures in critical systems.

Summary: This study investigates the thermalization dynamics after a quantum quench in confined systems and finds that it exhibits multiple stages. Taking the confined Ising spin chain as an example, bound states resembling mesons are formed. The system first reaches a prethermal state related to the number of conserved mesons, and then achieves true thermal equilibrium at much later times.

Summary: The majority of breast cancers are ER+, and agents targeting the ER signaling pathway have significantly improved survival for patients. However, therapeutic resistance is a challenge, particularly in metastatic cases. In recent years, disrupted epigenetic regulatory processes have been identified as major contributors to cancer development, including breast cancer. Aberrations in chromatin modifiers and transcription factors have also been associated with breast cancer development and treatment outcomes, leading to the proposal of new epigenetic-based therapies in combination with targeted treatments to overcome resistance.

Summary: As global warming intensifies, the earth's average temperature continues to rise. Plants have developed two main mechanisms, the heat stress response and the thermomorphogenesis response, to cope with elevated temperatures. This review summarizes recent progress in understanding these heat-responsive molecular regulatory pathways in plants and discusses future perspectives in this field.

Summary: Bcl11b, a critical transcription factor, plays context-dependent roles in the development of different cell types. Its chromatin binding activity is largely guided by interactions with other transcription factors, and it recruits multiple families of chromatin-modifying enzyme complexes to induce changes in regional suites of epigenetic modifications.

Summary: Acclimation to high temperature increases plants' tolerance of subsequent lethal high temperatures. The study reveals that JUMONJI H3K27me3 demethylases are essential for heat acclimation in Arabidopsis. This epigenetic memory mechanism involving histone demethylases could have significant implications for environmental adaptation of field plants.

Summary: H3K27me3 modification is a conserved epigenetic signal for transcriptional repression in plants and animals, with JMJ genes regulating the demethylation of H3K27 in Arabidopsis thaliana. Transcription of JMJ genes plays a crucial role in plant development and environmental responses, working synergistically with transcription factors and other epigenetic regulators.

Summary: Certain eukaryotic transcription factors have the ability to reprogram one cell type into another, with pioneer factors being able to engage target sites in closed chromatin. In plants, the TF LEAFY acts as a pioneer factor specifying floral fate and interacts with other factors to regulate floral development.

Summary: Cell cycle-coupled H3K27me3 dilution regulates floral development by controlling the expression timing of various target genes. The transcription factor AG prevents maintenance of H3K27me3 along the KNU coding sequence, allowing activation of KNU transcription prior to floral meristem termination. AHL18, a downstream target of AG, is specifically expressed in stamens and involved in stamen growth. Our findings highlight the importance of cell cycle-coupled H3K27me3 dilution in floral development and provide insights into the regulatory mechanisms.

Summary: Heat stress is a growing threat to food security due to global warming. Plants, as sessile species, have developed different mechanisms to cope with the disruption of cellular homeostasis caused by heat stress. This article summarizes the transcriptional regulation mechanisms mediated by transcription factors, epigenetic regulators, and regulatory RNAs in response to heat stress. Additionally, cellular activities such as protein homeostasis maintenance and regulation of ROS homeostasis are discussed. The harmonious regulation of plant cells allows them to adapt to unfavorable environments. Future studies on improving crop resilience to heat stress for urban agriculture are also suggested.

Summary: Unfavorable environmental conditions and climate change can cause yield losses in plants. Indonesian pigmented rice cultivars with high anthocyanin contents have great potential for cultivation, but their ability to grow in high-salinity lands is limited. In this study, we examined the effect of pre-treating the seeds with a halopriming solution on salt tolerance. Halopriming alleviated the negative effects of salinity on plant growth by reducing reactive oxygen species accumulation and increasing the stability of the membrane and photosynthetic pigment contents. The effects of halopriming on proline accumulation and stress-related gene expression varied among rice varieties.

Summary: This study computationally characterized the expression patterns of JMJ H3K27me3 demethylase genes using public transcriptome datasets, revealing JMJ30 to be highly expressed in the L1 layer of Arabidopsis shoot apical meristem and most affected by abiotic and biotic stress. The expression of JMJ30 varied among Arabidopsis thaliana accessions, suggesting that transcriptional changes of H3K27me3 demethylase genes may play key roles in development and environmental responses. Additionally, the expression of a JMJ30 orthologue from Arabidopsis halleri fluctuated under field conditions, further supporting the importance of these genes in plant adaptation.
