Effective neovascularization is critical for tissue repair and the enhancement of cardiac function following myocardial infarction (MI). However, the hypoxic microenvironment post-MI significantly impedes neovascular formation. Although ATF4 has been implicated in heart failure and myocardial cell regeneration and repair, its role in angiogenesis remains unclear.

Ferroptosis is a regulated form of cell death that is dependent on reactive oxygen species (ROS) and iron metabolism. Ferroptosis can participate in the formation and rupture of atherosclerotic plaque by regulating apoptosis. However, the mechanism of vascular endothelial cells (VECs) ferroptosis in the occurrence and development of atherosclerosis (AS) requires further exploration.

Unlabelled: Enhancing tissue repair and angiogenesis post-Acute myocardial infarction (AMI) is critical to improving cardiac function and preventing heart failure. Recent studies have highlighted the interaction between immune cells and endothelial cells in post-AMI angiogenesis, yet the specific contributions of different immune cell subsets remain poorly understood. Emerging evidence suggests the presence of a subset of regulatory T cells (Tregs) expressing Amphiregulin (AREG) in infarcted myocardial tissue, with AREG acting as a paracrine protein that plays a key role in angiogenesis.

Resistance to platinum-based chemotherapy agents like oxaliplatin (OXA) poses significant challenges in the treatment of cancers such as hepatocellular carcinoma (HCC). Centrin 2 (CETN2), which functions in nucleotide excision repair (NER) of DNA damage, is overexpressed in HCC. We investigated the potential role of CETN2 in modulating the sensitivity of HCC cells to OXA.

Type 1 diabetes mellitus (T1DM), known as insulin-dependent diabetes mellitus, is characterized by persistent hyperglycemia resulting from damage to the pancreatic β cells and an absolute deficiency of insulin, leading to multi-organ involvement and a poor prognosis. The progression of T1DM is significantly influenced by oxidative stress and apoptosis. The natural compound eugenol (EUG) possesses anti-inflammatory, anti-oxidant, and anti-apoptotic properties.

Background: Depressive symptoms in older adults have been a major public health problem. Although many studies have suggested a potential relationship between Internet use and depressive symptoms, the underlying mechanisms of this relationship among older adults remain unclear. This study aimed to explore the multiple mediating effects of physical exercise and self-rated health on the relationship between Internet use and depressive symptoms in older adults.

Marine heatwaves (MHWs) have become more frequent and intense in the context of rapid climate change, causing detrimental effects on marine bivalves and ecosystems they sustain. While selective breeding programs for bivalves can substantially enhance growth performance, their ability to improve thermal stress tolerance remains largely unexplored. Here, we compared physiological energetics of wild and selectively bred Hongkong oysters (Guihao No.

With sequence-programmable biological functions and excellent biocompatibility, synthetic functional DNA holds great promise for various biological applications. However, it remains a challenge to simultaneously retain their biological functions while protecting these fragile oligonucleotides from the degradation by nucleases abundant in biological circumstances. Herein, a smart delivery system for functional DNA payloads is developed based on proton-mediated dynamic nestling of cytosine-rich DNA moieties within the precisely size-matched nanochannels of highly crystalline metal-organic frameworks (MOFs): At neutral pH, cytosine-rich DNA strands exhibit a flexible single-stranded state and can be accommodated by MOFs nanochannels with a size of ca.

Epigenetic alterations in gene expression have been implicated in cancer development and tumor immune escape, with posttranslational histone or non-histone modifications representing attractive targets for disease surveillance and therapy. SET domain bifurcated 1 (SETDB1) is a histone lysine methyltransferase that reversibly catalyzes the di- and tri-methylation of histone 3 lysine 9 (H3K9) on euchromatin, inhibiting gene transcription within these regions and facilitating the switch from euchromatic to heterochromatic states. Emerging evidence suggests that SETDB1 amplification and aberrant activation are significantly associated with poor prognosis in hepatocellular carcinoma (HCC), and contribute to HCC development, immune escape, and immune checkpoint blockade (ICB) resistance.

Article Synopsis
  • - The study investigates how hypoxia (low oxygen levels) impacts the metabolism and antioxidant capacity of a commonly farmed oyster species in China by measuring factors like total antioxidant capacity, glycogen content, and specific enzyme activities under varying oxygen conditions.
  • After 6 hours of hypoxia, key metabolic indicators significantly dropped, but after 72 hours, they increased, and reoxygenation for 24 hours helped restore many of the initial levels.
  • A transcriptome analysis identified 6097 novel genes and several differentially expressed genes (DEGs) related to hypoxia adaptation, providing insights into potential molecular mechanisms that help these oysters survive low-oxygen environments.
