Abstract

Structural information on oligosaccharides was obtained by post-source decay matrix-assisted laser desorption/ionization mass spectrometry. A systematic study of derivatized oligosaccharides showed that products relatively aminated with benzylamine allow the formation of [M+H]+ molecular species. Metastable protonated species decompose in the field-free region (post-source decay) to yield predictable and reproducible fragmentation patterns. Information on sugar sequence and branching can be derived from such mass spectra.

Increased acetylation of H3K14 in the genomic regions that encode trained immunity enzymes in lysophosphatidylcholine-activated human aortic endothelial cells - Novel qualification markers for chronic disease risk factors and conditional DAMPs.

To test our hypothesis that proatherogenic lysophosphatidylcholine (LPC) upregulates trained immunity pathways (TIPs) in human aortic endothelial cells (HAECs), we conducted an intensive analyses on our RNA-Seq data and histone 3 lysine 14 acetylation (H3K14ac)-CHIP-Seq data, both performed on HAEC treated with LPC. Our analysis revealed that: 1) LPC induces upregulation of three TIPs including glycolysis enzymes (GE), mevalonate enzymes (ME), and acetyl-CoA generating enzymes (ACE); 2) LPC induces upregulation of 29% of 31 histone acetyltransferases, three of which acetylate H3K14; 3) LPC induces H3K14 acetylation (H3K14ac) in the genomic DNA that encodes LPC-induced TIP genes (79%) in comparison to that of in LPC-induced effector genes (43%) including ICAM-1; 4) TIP pathways are significantly different from that of EC activation effectors including adhesion molecule ICAM-1; 5) reactive oxygen species generating enzyme NOX2 deficiency decreases, but antioxidant transcription factor Nrf2 deficiency increases, the expressions of a few TIP genes and EC activation effector genes; and 6) LPC induced TIP genes(81%) favor inter-chromosomal long-range interactions (CLRI, trans-chromatin interaction) while LPC induced effector genes (65%) favor intra-chromosomal CLRIs (cis-chromatin interaction). Our findings demonstrated that proatherogenic lipids upregulate TIPs in HAECs, which are a new category of qualification markers for chronic disease risk factors and conditional DAMPs and potential mechanisms for acute inflammation transition to chronic ones. These novel insights may lead to identifications of new cardiovascular risk factors in upregulating TIPs in cardiovascular cells and novel therapeutic targets for the treatment of metabolic cardiovascular diseases, inflammation, and cancers.

Increased expression of integrin beta1 subunit enhances p21WAF1/Cip1 transcription through the Sp1 sites and p300-mediated histone acetylation in human hepatocellular carcinoma cells.

Integrins, a class of membrane receptors, are major players in transmitting the mechanical force across the plasma membrane. We previously reported that overexpression of integrin beta1 subunit imposed a growth inhibitory effect on the hepatocellular carcinoma cell line SMMC-7721 through transcriptional activation of p21(WAF1/CIP1) gene. In this study, we further determined the molecular mechanisms underlying p21(WAF1/CIP1) expression induced by integrin beta1 overexpression. We report herein that overexpression of integrin beta1 subunit upregulates p21(WAF1/Cip1) transcription through a p53-independent pathway. The overexpressed integrin beta1 activates the p21(WAF1/Cip1) promoter through the Sp1/Sp3 sites and makes more transcription factor Sp1 recruited to the proximal p21 promoter region. In addition, it makes the acetylation value of histone proteins increased across some parts of the p21(WAF1/Cip1) gene, especially in the promoter region. The transcriptional co-activator p300, which possesses intrinsic histone acetyltransferase, was found to be involved in the integrin beta1-mediated histone acetylation and p21 transcriptional activation. Therefore, these findings presented the mechanisms by which integrin beta1 induced the elevated p21 expression in hepatic cancer cells.

Max is acetylated by p300 at several nuclear localization residues.

Max is a ubiquitous transcription factor with a bHLHZip [basic HLH (helix-loop-helix) leucine zipper] DNA-binding/dimerization domain and the central component of the Myc/Max/Mad transcription factor network that controls cell growth, proliferation, differentiation and apoptotic cell death in metazoans. Max is the obligatory DNA-binding and dimerization partner for all the bHLHZip regulators of the Myc/Max/Mad network, including the Myc family of oncoproteins and the Mad family of Myc antagonists, which recognize E-box DNA elements in the regulatory regions of target genes. Max lacks a transcription regulatory domain and is the only member of the network that efficiently homodimerizes. Binding of Max homodimers to E-box elements suppresses the transcription regulatory functions of its network partners and of other non-network E-box-binding regulators. In contrast with its highly regulated partners, Max is a constitutively expressed and phosphorylated protein. Phosphorylation is, however, the only Max post-translational modification identified so far. In the present study, we have analysed Max posttranslational modifications by MS. We have found that Max is acetylated at several lysine residues (Lys-57, Lys-144 and Lys-145) in mammalian cells. Max acetylation is stimulated by inhibitors of histone deacetylases and by overexpression of the p300 co-activator/HAT (histone acetyltransferase). The p300 HAT also directly acetylates Max in vitro at these three residues. Interestingly, the three Max residues acetylated in vivo and in vitro by p300 are important for Max nuclear localization and Max-mediated suppression of Myc transactivation. These results uncover novel post-translational modifications of Max and suggest the potential regulation of specific Max complexes by p300 and reversible acetylation.
