Summary: Epigenetic modifications undergo erasure and reestablishment after fertilization, with some histone modifications escaping reprogramming. In nonmammalian vertebrates, most histone modifications are thought to be intensively erased and reestablished. However, the histone modifications that escape reprogramming in nonmammalian vertebrates and their potential functional roles remain unknown.

Summary: Obesity is a major public health concern characterized by an increase in adipose tissue mass, which can lead to impaired metabolic health and even influence cancer progression. Dysfunction in adipocyte function is influenced by genetics and environmental factors, affecting gene expression and onset of obesity. Understanding the complexities of adipogenesis is crucial for recognizing disease conditions and identifying therapeutic interventions.

Summary: Chromatinopathies are genetic disorders caused by mutations in genes involved in chromatin state balance. There are 82 human conditions described so far, sharing molecular features and clinical signs. Combining clinical and basic research is essential for understanding the molecular cascade and exploring therapeutic strategies. Animal models are invaluable tools for studying chromatinopathies.

Summary: Researchers have focused on the epigenetic control of DNA-templated processes for many years. Epigenetic modifications like histone modification, DNA methylation, chromatin remodeling, RNA modification, and noncoding RNAs play a crucial role in the development of cancers. Dysregulation of the epigenome leads to abnormal transcriptional programs, and targeting the dysregulated epigenetic modifications might be an effective strategy for cancer treatment. Additionally, epigenetics influences tumor immunogenicity and immune cells involved in antitumor responses, suggesting the potential of combining epigenetic therapy and cancer immunotherapy for better cancer treatment.

Summary: Modifications to DNA and core histones play crucial roles in chromatin organization and gene expression, affecting various biological processes. Studies have identified genes encoding enzymes that modify core histones in multiple insect genomes, with some enzymes contributing to post-embryonic development. Research on epigenetic modifiers could help identify inhibitors that may be used to control pests and disease vectors.

Summary: The establishment, maintenance, and removal of epigenetic modifications in plants provide an additional layer of regulation beyond genetic factors, allowing for control of developmental processes and adaptation to the environment. Epigenetic inheritance, which can refer to information not encoded in the DNA sequence inherited between generations or epigenetic modifications reset between generations, is of great interest in understanding the functions and mechanisms in plants. This article discusses examples of epigenetic dynamics and maintenance during growth and development stages and their functional consequences, as well as the dynamic nature of epigenetic states in response to stress and their impact on transposable element regulation. The emerging area of research focuses on understanding how epigenetic resetting occurs during normal development and in response to stress.

Summary: This study investigates the TNK2 gene variants in Parkinson's disease (PD) patients and their potential impact on dopaminergic neurodegeneration. The findings suggest that TNK2 dysfunction may contribute to PD, possibly through sustained or aberrant activity. The study also highlights the importance of TNK2 and its ortholog SID-3 in coordinating dopaminergic and epigenetic signaling. Experimental results using Caenorhabditis elegans and rat primary neurons demonstrate the neuroprotective effects of TNK2 inhibition and NEDD4 activation.

Summary: TET proteins oxidize 5-methylcytosine to facilitate DNA demethylation and serve as novel epigenetic marks. Loss of TET function is strongly associated with cancer, especially in hematological malignancies. TET proteins govern cell fate decisions by activating cell-specific gene expression programs.

Summary: Endometriosis is positively associated with obesity, but negatively associated with low BMI. High-fat diet-induced obesity can increase the development of endometriosis, while obesity with leptin deficiency and leptin receptor deficiency can suppress the development of endometriosis. These findings suggest that leptin and its receptor play a critical role in the development of endometriosis.

Summary: The adverse effects of air pollutants on the respiratory and cardiovascular systems are well-known, but recent studies have found that they also have negative effects on the neurological system and cognitive function. Ultrafine particles (UFPs) play a key role in these effects, but there is still limited understanding about the smallest fraction and semivolatile compounds. The TUBE project aims to increase knowledge about harmful UFPs and semivolatile compounds, provide information for better emission legislation, and assess the impact of air pollution on the brain and its removal.

Summary: This article proposes an in vitro multi-organ strategy to assess the toxicity of chemicals using human induced pluripotent stem cells (hiPSCs)-derived models. The strategy allows parallel evaluation of chemical toxicity on multiple tissues/organs, exclusively in human cells, eliminating interspecies bias and increasing the chance to identify toxic compounds. The authors demonstrated the strategy by generating models of brain, blood-brain barrier, kidney, liver, and vasculature and exposing them to paraquat, highlighting their differential cytotoxic sensitivity and the deregulation of key signaling pathways.

Summary: Stem cell therapy has the potential to replace beta-cell loss in diabetic patients, but maintaining the viability and function of the engrafted cells is a key challenge. A near-infrared fluorescent mutant version of a bacteriophytochrome, iRFP720, has been developed for in vivo imaging and stem/progenitor cell tracking. Researchers have successfully generated an iRFP720 expressing human induced pluripotent stem cell (iPSC) line using the CRISPR/Cas9 technology, which allows for real-time imaging in various biological applications.

Summary: This study used six human derived cell models to investigate the effects of trichloroethylene (TCE) S-conjugates. The results showed that TCE S-conjugates induced Nrf2 pathway and unfolded protein response, which may explain the nephrotoxicity and neurotoxicity of TCE. This study expands our knowledge on the tissue specificity of TCE S-conjugates and highlights the value of human cell models and transcriptomics in mechanistic studies.

Summary: Evidence suggests that protein-bound polyphenols can alleviate type 2 diabetes mellitus (T2DM). This study investigated the modulation of myofibrillar protein-chlorogenic acid (MP-CGA) complexes on T2DM rats from the gut microbiota perspective. Results showed that MP-CGA improved hyperglycemia and hyperlipidemia, reduced intestinal inflammation, and reconstructed gut microbiota by promoting beneficial bacteria and suppressing opportunistic pathogens. MP-CGA also elevated the concentrations of intestinal metabolites that regulate T2DM positively. Therefore, MP-CGA can modulate the gut microbiota and related metabolites to maintain stable blood glucose in T2DM rats.
