Quercetin-Induced Lifespan Extension in Podospora anserina Requires Methylation of the Flavonoid by the O-Methyltransferase PaMTH1

open access: yesFrontiers in Genetics, 2018
Quercetin is a flavonoid that is ubiquitously found in vegetables and fruits. Like other flavonoids, it is active in balancing cellular reactive oxygen species (ROS) levels and has a cyto-protective function.

Smoking-induced long-lasting modifications of human platelet serotonin catabolism through a MAO epigenetic regulation [PDF]

open access: yes, 2008
Postulating that serotonin, secreted from smoking-activated platelets, could be involved in smoking-induced vascular modifications, we studied 115 men distributed in smokers (S), former smokers (FS) and never smokers (NS).

Positive Feedback Loop of Histone Lactylation‐Driven HNRNPC Promotes Autophagy to Confer Pancreatic Ductal Adenocarcinoma Gemcitabine Resistance

open access: yesAdvanced Science, EarlyView.
Histone 3 lysine18 lactylation (H3K18la) drives heterogeneous nuclear ribonucleoprotein C (HNRNPC) overexpression, activating autophagy to mediate gemcitabine resistance by stabilizing TNF receptor‐associated factor 6 (TRAF6) mRNA. Concurrently, HNRNPC stabilizes aldehyde dehydrogenase 1 family member A3 (ALDH1A3) mRNA, which enhances glycolysis and ...

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

open access: yesAdvanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Mammalian Proteome Profiling Reveals Readers and Antireaders of Strand‐Symmetric and ‐Asymmetric 5‐Hydroxymethylcytosine‐Modifications in DNA

open access: yesAdvanced Science, EarlyView.
ABSTRACT The cytosine (C) modifications 5‐methylcytosine (mC) and 5‐hydroxymethylcytosine (hmC) are central regulatory elements of mammalian genomes. Both marks occur in double‐stranded DNA in either strand‐symmetric or ‐asymmetric fashion, but it is still poorly understood how this symmetry information is selectively read out by the nuclear proteome ...

Engineering Osteoimmune Responses with Functionalized Orthopedic Implants for Post‐Operative Osteosarcoma Treatment

open access: yesAdvanced Science, EarlyView.
Osteosarcoma is the most common primary bone tumor with limited treatment options and a terrible prognosis. This review provides a comprehensive summary of the recent development of osteoimmunomodulatory implants for post‐operative osteosarcoma treatment, of which the potential utility in evoking durable anti‐osteosarcoma immunity and accelerating bone

METTL5 Enables Immune Evasion of Liver Cancer via Chemokine mRNA Translation Regulation

open access: yesAdvanced Science, EarlyView.
METTL5 reshapes the tumor immune microenvironment through ribosome 18S rRNA m6A modification to regulate the translation of chemokine mRNA. Targeting METTL5‐mediated immunosuppression unleashes anti‐tumor immunity and improves the efficacy of anti‐PD‐1 therapy.

Cannabinoid-Inspired Inhibitors of the SARS-CoV-2 Coronavirus 2′-O-Methyltransferase (2′-O-MTase) Non-Structural Protein (Nsp10–16)

open access: yesMolecules
The design and synthesis of antiviral compounds were guided by computationally predicted data against highly conserved non-structural proteins (Nsps) of the SARS-CoV-2 coronavirus.
