Inhibitors of Protein Methyltransferases and Demethylases

open access: yesChemical Reviews, 2017
Post-translational modifications of histones by protein methyltransferases (PMTs) and histone demethylases (KDMs) play an important role in the regulation of gene expression and transcription and are implicated in cancer and many other diseases. Many of these enzymes also target various nonhistone proteins impacting numerous crucial biological pathways.

Unraveling the epigenetic code in cancer cell–tumor microenvironment crosstalk

open access: yesMolecular Oncology, EarlyView.
Epigenetic regulation is a key driver of cancer development and progression. Diverse epigenetic alterations in cancer cells and components of the tumor microenvironment (TME) orchestrate their communication through multiple mechanisms. We discuss how the epigenetic code coordinates bidirectional cancer cell–TME crosstalk to promote cancer progression ...

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

open access: yesMolecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

3D Bioprinted Glioblastoma Multiforme Models: How the Extracellular Matrix Glycosignature Influences Drug Response

open access: yesAdvanced Functional Materials, EarlyView.
Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

DNA Demethylase Is a Processive Enzyme

open access: yesJournal of Biological Chemistry, 1999
DNA methylation patterns are generated during development by a sequence of methylation and demethylation events. We have recently demonstrated that mammals bear a bona fide demethylase enzyme that removes methyl groups from methylated cytosines. A general genome wide demethylation occurs early in development and in differentiating cell lines.

In Vitro Histone Demethylase Assay [PDF]

open access: yesCold Spring Harbor Protocols, 2010
INTRODUCTIONPost-translational modifications of histones play an important role in regulating chromatin dynamics and function. One of the modifications, methylation, occurs on both lysine and arginine residues, and methylation status defines the epigenetic program of a cell by determining chromatin structure and thereby regulating DNA-dependent ...

Dual Role of Tamoxifen in Enhancing STING and CEACAM1 Expression to Prime a Favorable Tumor Microenvironment for Anti‐TIM3 Immunotherapy

open access: yesAdvanced Science, EarlyView.
Anti‐PD‐1/PD‐L1 blockade has revolutionized cancer immunotherapy, but is ineffective against endocrine‐treated (i.e., Tamoxifen), relapsed ER+ breast cancer (BC) patients. This study provides insight into the sub‐optimal response of ER+BCs to anti‐PD‐1/PD‐L1 blockade – highlighting the induction of STING and the CEACAM1/TIM3 axis after chronic ...

Demethylase ALKBH4 Inhibits Cell Proliferation via Induction of 5′-tsRNAGlu in Non-Small Cell Lung Cancer

open access: yesFrontiers in Bioscience-Landmark
Background: Transfer RNA (tRNA)-derived small RNAs (tsRNAs) are an emerging class of small non-coding RNAs that play critical roles in tumor progression; however, the functions and underlying mechanisms of tsRNAs in lung cancer ...

The histone demethylase lysine-specific demethylase-1–mediated epigenetic silence of KLF2 contributes to gastric cancer cell proliferation, migration, and invasion

open access: yesTumor Biology, 2017
Gastric cancer is one of the most common malignancies and leading causes of cancer-related death worldwide. An increasing number of evidence has revealed that gastric tumorigenesis is a multistage pathological state, and epigenetic alterations are ...

Characterization of drug metabolizing enzymes and assessment of aging in the gilthead seabream (Sparus aurata) liver

open access: yesVeterinární Medicína, 2010
Organic anthropogenic compounds such as polycyclic aromatic hydrocarbons, polychlorinated biphenyls, nitroaromatics, dioxins, various pesticides and natural compounds can enter the aquatic environment. These lipophilic compounds are readily taken up into
