The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Structure–Activity Relationship of Pyrrolidine Pentamine Derivatives as Inhibitors of the Aminoglycoside 6′-N-Acetyltransferase Type Ib

Antibiotics
Resistance to amikacin and other major aminoglycosides is commonly due to enzymatic acetylation by the aminoglycoside 6′-N-acetyltransferase type I enzyme, of which type Ib [AAC(6′)-Ib] is the most widespread among Gram-negative pathogens.

Characterization and epitope mapping of human monoclonal antibodies to PDC-E2, the immunodominant autoantigen of primary biliary cirrhosis [PDF]

, 1992
Further to define the epitopes of PDC-E2, the major autoantigen in primary biliary cirrhosis (PBC), we have developed and characterized five human monoclonal antibodies. These antibodies were derived by fusing a regional hepatic lymph node from a patient

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

Advanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Aminoglycoside resistance profile and structural architecture of the aminoglycoside acetyltransferase AAC(6’)-Im

Microbial Cell, 2017
Aminoglycoside 6’-acetyltransferase-Im (AAC(6’)-Im) is the closest monofunctional homolog of the AAC(6’)-Ie acetyltransferase of the bifunctional enzyme AAC(6’)-Ie/APH(2”)-Ia.

Polyglutamine Disease: Acetyltransferases Awry [PDF]

Current Biology, 2002
Recent evidence indicates that inhibition of histone acetyltransferases may be a primary cause of cellular pathogenesis in polyglutamine diseases such as Huntington disease; the results raise the possibility that pharmacologic manipulation of protein acetylation levels could be of therapeutic benefit.

Eco‐Fabricated Nanowave‐Textured Implants Drive Microtubule‐Assisted Nuclear Mechanotransduction and Chromatin Modification: Biophysical Priming for Osteogenesis and Bone Regeneration

Advanced Functional Materials, EarlyView.
Eco‐friendly nanowave‐textured implants produced via femtosecond laser fabrication enhance bone regeneration by orchestrating a precise mechanotransduction cascade. This nanotopography directs mesenchymal stem cell alignment and cytoskeletal organization, triggering changes in nuclear shape and chromatin acetylation that prime cells for osteogenesis ...

A degenerate PCR-based strategy as a means of identifying homologues of aminoglycoside and ß-lactam resistance genes in the gut microbiota [PDF]

, 2014
peer-reviewedBackground: The potential for the human gut microbiota to serve as a reservoir for antibiotic resistance genes has been the subject of recent discussion. However, this has yet to be investigated using a rapid PCR-based approach.

Characterization of Rat Hepatic Acetyltransferase

Environmental Health Perspectives, 1994
Rat liver cytosol is capable of N-acetylation (NAT) of arylamines, O-acetylation (OAT) of arylhydroxylamines, and N,O-acetyltransfer (AHAT) of arylhydroxamic acids. Physical, enzymatic, and immunochemical techniques now support the conclusion that a single 32 kDa protein accounts for all of these activities.

SMYD3 Promotes Immune Evasion in Clear Cell Renal Cell Carcinoma via SREBP1‐Mediated Transactivation of CD47

Advanced Science, EarlyView.
Cancer cell‐intrinsic SMYD3 orchestrates an immunosuppressive microenvironment and impairs the response to PD‐1 blockade by reprogramming immune cells landscape in the tumor microenvironment of clear cell renal cell carcinoma (ccRCC). The immunomodulatory function of SMYD3 is mediated via the SREBP1/CD47 pathway.
