How does ZMYND11 promote the spreading of histone posttranslational modificaitons? 


Best insight from top research papers

ZMYND11, a candidate tumor suppressor, plays a crucial role in recognizing histone modifications, specifically H3K36 trimethylation on the histone variant H33, regulating transcription elongation. ZMYND11 acts as a 'reader' of these modifications, accumulating on gene bodies during transcription and modulating RNA polymerase II elongation. By recognizing H3K36me3 on H33, ZMYND11 influences the elongation stage of transcription, repressing a transcriptional program essential for tumor cell growth. Additionally, ZMYND11's occupancy in gene bodies requires the pre-deposition of H33K36me3, showcasing its specificity in recognizing and regulating histone modifications. This mechanism links histone variant-mediated transcription control to tumor suppression, highlighting ZMYND11's role in promoting the spreading of histone posttranslational modifications.

How does Histone Modifications in prokaryotes and eukaryotes?3 answersHistone modifications play a crucial role in both prokaryotes and eukaryotes. In eukaryotes, DNA is condensed into chromatin, and posttranslational modifications of nucleosomes regulate accessibility to the DNA sequence. These modifications are deposited and removed by specific machineries and are distributed throughout the genome. They are involved in key cellular processes such as transcriptional regulation and DNA repair. In prokaryotes, recent studies have shown the presence of alternative histones with different DNA binding properties, as well as highly divergent sequences. These new histones, identified in metagenomes, have been categorized into distinct groups based on in-silico protein structure predictions. Some prokaryotic histones bridge DNA instead of wrapping it, diverging from conventional nucleosomal histones. Overall, histone modifications in both prokaryotes and eukaryotes contribute to the regulation of gene expression and chromatin-based processes.

What type of cells have the highest rRNA transcirption?
10 answers
The transcription of ribosomal RNA (rRNA) varies significantly across different cell types, reflecting the diverse roles and activities of these cells. In the study of parsley, carrot, and Acer pseudoplatanus cells, a high molecular weight rRNA precursor was detected, indicating active rRNA transcription in these plant cells, although the study primarily focused on the molecular weight and presence of rRNA precursors rather than transcription rates. Similarly, in pollen grains of various plant species, high-density rRNA in generative/sperm cells suggests a general characteristic of mature pollen grains, implying significant rRNA transcription activity in these cells. In contrast, HeLa cells, rat liver, and Xenopus laevis oocytes showed high incidence of rRNA localization in nucleoli and cytoplasmic areas containing ribosomes, with nucleoli of HeLa cells and rat hepatocytes showing greater labeling, indicating active rRNA transcription in these regions. The replication patterns of rRNA genes in synchronized pea root cells also provide insight into the temporal dynamics of rRNA transcription, suggesting active transcription processes during specific phases of the cell cycle. Human embryonic stem cells (hESCs) undergoing directed differentiation exhibited a significant reduction in rRNA synthesis rate, highlighting the dynamic regulation of rRNA transcription in response to differentiation cues. Studies on wastewater-treatment systems and the role of microbial communities therein revealed that both abundant and rare taxa contribute to rRNA transcription, with rare taxa showing disproportionally high ratios of rRNA to DNA, suggesting active transcription in these communities. In mammalian cells, despite robust changes in rRNA transcription rates, no significant variation in active gene number was found after growth stimulation, indicating that transcriptional enhancement does not necessarily correlate with an increase in active gene count. Research on lymphosarcoma P1798 cell lines and the effect of dexamethasone on transcription initiation from the rDNA promoter further underscores the complexity of transcriptional regulation in different cell contexts. The impact of nucleoside analogues on rRNA transcription and processing in Ehrlich ascites cells and BHK21 cells demonstrates the sensitivity of rRNA transcription to external chemical stimuli. Lastly, the analysis of bacterial diversity in heavy metal-contaminated soils revealed that Actinobacteria, particularly the Rubrobacteria subgroup, dominate rRNA-derived libraries, suggesting high metabolic and transcriptional activity in these bacteria under stress conditions. Considering the evidence across various studies, it appears that cells with high metabolic demands or those undergoing significant changes, such as differentiation in hESCs, or cells in specific environmental contexts, such as bacteria in contaminated soils, exhibit high levels of rRNA transcription. However, the Actinobacteria in heavy metal-contaminated soils stand out due to their dominance in rRNA libraries, indicating they might have the highest rRNA transcription activity under the conditions studied.

What concentration of anacardic acid in vitro inhibits p300 without killing cells?
10 answers
Anacardic acid, a bioactive compound derived from cashew nut shell liquid, has been extensively studied for its inhibitory effects on p300, a histone acetyltransferase (HAT) involved in various cellular processes including cell cycle regulation and gene expression. The concentration of anacardic acid required to inhibit p300 without inducing cytotoxicity varies across different cell types and experimental setups, as evidenced by the research contexts provided. In the study of LNCaP cells (prostate cancer cells), anacardic acid was found to inhibit cell proliferation and induce G1/S cell cycle arrest and apoptosis, suggesting its potent anti-tumor activities. However, the specific concentration used for inhibiting p300 without killing cells was not explicitly mentioned. Similarly, in isolated neonatal rat cardiomyocytes, anacardic acid prevented hypertrophy induced by various agents, indicating its role in inhibiting p300, but again, the non-toxic concentration specific to p300 inhibition was not detailed. Research on human umbilical vascular endothelial cells (HUVECs) demonstrated that anacardic acid could suppress VEGF-induced cell proliferation, migration, and other angiogenesis-related activities, implicating its effect on p300 through different signaling pathways, yet without specifying the exact non-lethal concentration for p300 inhibition. In the context of cardiac hypertrophy, anacardic acid was shown to attenuate phenylephrine-induced hypertrophy by modulating histone acetylation, with a focus on the JNK/MAPK signaling pathway rather than direct p300 inhibition concentrations. For breast cancer MDA-MB-231 cells, anacardic acid exhibited a modest ATPase inhibition activity with an IC50 value of 82.5 µmol/L, and significantly suppressed cell proliferation at an IC50 value of 29.3 µmol/L. This suggests that concentrations below 29.3 µmol/L might inhibit p300 without killing cells, at least in this cell line. However, it's important to note that cytotoxic effects and the concentration threshold for p300 inhibition can vary significantly across different cell types and experimental conditions. In studies focusing on other aspects of anacardic acid's biological activities, such as its effects on atherosclerosis, cardiac hypertrophy, leukemia treatment, pancreatic cancer, and antimicrobial properties, the specific concentrations effective for p300 inhibition without inducing cytotoxicity were not directly addressed. Therefore, while anacardic acid is recognized for its potential to inhibit p300, determining the exact concentration that achieves this without causing cell death requires further investigation specific to each cell type and context.
