NAT10‐Mediated ac4C Modification of circANKRD12 Reprograms the Tumor Microenvironment

Advanced Science, EarlyView.
NAT10‐dependent acetylation of circANKRD12 drives translation of the circANKRD12_354aa protein, which binds HDAC2 to stabilize c‐Myc via deubiquitination, promoting multiple myeloma (MM) cell proliferation. Concurrently, the circANKRD12‐HDAC2 axis suppresses H3ac‐mediated transcription of IFN‐γ, TNF‐α, and GZMB in NK cells, leading to NK cell ...

Epigenetic Regulation of Matrix Metalloproteinase-1 and -3 Expression in Mycobacterium tuberculosis Infection

Frontiers in Immunology, 2017
In pulmonary tuberculosis (TB), the inflammatory immune response against Mycobacterium tuberculosis (Mtb) is associated with tissue destruction and cavitation, which drives disease transmission, chronic lung disease, and mortality.

Characterization of novel inhibitors of histone acetyltransferases [PDF]

Molecular Cancer Therapeutics, 2007
Abstract Modification of proteins by histone acetyltransferases (HAT) or histone deacetylases plays an important role in the control of gene expression, and its dysregulation has been linked to malignant transformation and other diseases.

A Non‐Canonical Role of SMAD4 in Regulating 3D Genome Architecture to Inhibit Lung Squamous Cell Carcinoma Development

Advanced Science, EarlyView.
SMAD4 is identified as a guardian of 3D genome architecture in lung squamous cell carcinoma. Loss of SMAD4 unleashes EP300 at chromatin loop anchors, strengthening enhancer–promoter looping and H3K27ac at the SOX2 locus to drive aberrant SOX2 activation and tumor cell proliferation.

Early butyrate induced acetylation of histone H4 is proteoform specific and linked to methylation state

Epigenetics, 2018
Histone posttranslational modifications (PTMs) help regulate DNA templated processes; however, relatively little work has unbiasedly explored the single-molecule combinations of histone PTMs, their dynamics on short timescales, or how these preexisting ...

Histone Deacetylase Inhibitors as Anticancer Drugs

International Journal of Molecular Sciences, 2017
Carcinogenesis cannot be explained only by genetic alterations, but also involves epigenetic processes. Modification of histones by acetylation plays a key role in epigenetic regulation of gene expression and is controlled by the balance between histone ...

p300 Degradation by the p53‐SIAH1 Axis Relieves TBK1 Acetylation to Enhance Innate Antiviral Immunity

Advanced Science, EarlyView.
This study identifies p300 as the acetyltransferase that acetylates TBK1 and inhibits its phosphorylation. Activation of the p53‐SIAH1 axis by immune response downregulates p300 expression to sustain innate antiviral immunity. Conditional p300 knockout in alveolar epithelial cells in vivo promotes antiviral responses and suppresses virus replication ...

A pervasive role of histone acetyltransferases and deacetylases in an NF-kappaB-signaling code. [PDF]

, 2008
Most nuclear factor-kappaB (NF-kappaB) inducers converge to activate the IkappaB kinase (IKK) complex, leading to NF-kappaB nuclear accumulation. However, depending on the inducer and the cell line, the subset of NF-kappaB-induced genes is different ...

Epigenetics in ovarian cancer: premise, properties, and perspectives

Molecular Cancer, 2018
Malignant ovarian tumors bear the highest mortality rate among all gynecological cancers. Both late tumor diagnosis and tolerance to available chemical therapy increase patient mortality.
