A new study reveals that two key BET proteins, BRD2 and BRD4, perform distinct roles in gene activation. Blocking both simultaneously disrupts the process, producing unpredictable effects. Targeted therapies may be more effective if they distinguish between these roles.
The study reveals how nutrients and lipids shape bone marrow blood stem cells from health to aging and leukemia, identifying choline as a key player. Healthy stem cells had high choline levels, which decreased with specialization and aging, suggesting nutritional interventions could maintain stem cell function.
A study by Max Planck researchers reveals that the ELAV protein acts as a global master switch for circular RNA (circRNA) production in neurons. The discovery explains the high prevalence of circRNAs in the nervous system, which are crucial for development and synaptic function.
Researchers at the Max Planck Institute discovered that mast cells can trap and recycle neutrophils, which are normally frontline defenders against infections. This unexpected interaction reveals a new layer to our understanding of allergic reactions and inflammation.
Research reveals a mechanism by which daughter cells safeguard themselves against UV-damaged RNA inherited from mother cells. DHX9 stress granules, a special type of stress granule, trap and neutralize damaged RNA to prevent harm.
A study by Max Planck researchers has discovered an epigenetic regulator MSL2 that ensures the expression of both alleles of haploinsufficient genes, crucial for human health. This mechanism allows for tissue- and cell-type specificity in gene dosage, opening new directions for understanding diseases and developing potential treatments.
The study reveals MOF's critical role in maintaining mitochondrial integrity through protein acetylation. COX17 is identified as a key target of MOF-mediated acetylation, stimulating its function and regulating oxidative phosphorylation.
The NSL complex controls intraciliary transport genes essential for cilia formation and function. Loss of the complex leads to impaired assembly and activation of these genes, resulting in ciliopathies characterized by hearing loss, visual impairment, and kidney disease.
Researchers at the Max Planck Institute found that specific start sites (TSSs) are linked to distinct end sites (TESs), shaping the RNA landscape unique to each tissue. Dominant promoters, which overrule conventional signals, drive this process and are conserved across species.
Researchers from the Max Planck Institute of Immunobiology and Epigenetics have identified a novel anti-bacterial pathway involving the inter-organellar crosstalk between phago-lysosomes and mitochondria. This pathway, mediated by TFEB, inhibits Salmonella growth in macrophages.
Researchers at the Max Planck Institute of Immunobiology and Epigenetics have identified two bipotent progenitor populations of thymic epithelial cells that control thymus formation at different stages of life. This discovery has significant implications for understanding immune system development and age-related changes, such as reduc...
Hematopoietic stem cells use RNA from junk DNA to enhance activation after chemotherapy, leading to increased inflammatory signaling and faster blood cell production. This mechanism helps improve blood regeneration after chemotherapy.
Neutrophils use an internal start-stop system to balance search and destroy phases for efficient pathogen elimination. This system helps prevent excessive inflammation and tissue damage. The study provides new insights into neutrophil biology, essential for immune host defense against bacteria.
Researchers discovered that HP1a is required to establish proper chromatin structure at multiple hierarchical levels during early embryonic development. The protein plays a central role in maintaining individual chromosome integrity and establishing the global structure of the genome.
A recent study has linked Interleukin-33 to immunity against Sars-CoV-2. The researchers found that memory T cells and high levels of antibodies persisted in recovered patients, suggesting a strong immune response. This discovery could pave the way for better understanding of Sars-CoV-2 immunity and potential therapies.
A team of scientists found that sulfur metabolism plays a crucial role in the transition from single-celled to multicellular organisms. By manipulating sulfur levels, they were able to induce or prevent the formation of multicellular aggregates in the slime mold Dictyostelium discoideum. This discovery has significant implications for ...
Cells form 'lockdown' strategy by slowing down gene activity when stressed, allowing resources to be diverted for crisis response. NELF protein condensation plays key role in this process.
A team of researchers has discovered a novel gel-like state that enables male fruit flies to compensate for their single X chromosome. The mechanism, which involves the assembly of roX-MSL2 gel, allows the complex to distinguish and mark the X chromosome. This innovation sheds light on how dosage compensation is achieved in male flies.
Researchers have generated a single-cell atlas of mouse innate lymphoid cells in the lung, discovering a pool of local progenitors that can generate mature ILC2s. The study reveals the complexity of ILC2 functions and their developmental relationships, shedding light on how they contribute to immune defense and inflammatory diseases.
Researchers found that anglerfishes with permanent attachments lack key immune molecules, leading to a severely blunted immune response. Instead, they rely on improved innate immune facilities to defend themselves against infections.
Blood vessels in the brain have evolved to form a protective barrier, but recent research shows they can also sense the metabolic state of neighboring neural cells. This allows them to respond to changes in nutrient availability and prevent disease states such as Alzheimer's and vascular dementia.
Researchers found that a specific histone modification, H4K16ac, is essential for embryonic development and drives gene activation in fruit fly offspring. The study suggests that mothers pass this information to their children through epigenetic modifications.
Researchers identified how the enzyme MOF orchestrates the HSC fate in erythropoiesis, revealing crucial role in regulating chromatin accessibility and gene expression. This discovery could lead to new therapeutic approaches for diseases such as leukemia or anemia.
The study reveals that jawless and jawed vertebrates share similar adaptive immune systems, despite independent evolution for over 500 million years. The researchers used CRISPR/Cas9 to disable a gene in lampreys, showing that they rely on a shared tool-kit to create antibodies.
The study revealed that loss of Lamin A/C acetylation results in softened nuclei prone to mechanical pressure and eventual breaking. Nuclear blebs and micronuclei are more likely to form under these conditions, posing a risk to genetic material integrity.
A comprehensive cell atlas of the human liver reveals previously unknown subtypes of liver cells, including hepatocytes, endothelial cells, and macrophages. The study provides unprecedented resolution into liver cell diversity and how it changes during development or upon disease progression.
