Monitoring of cellular senescence by DNA‐methylation at specific CpG sites

open access: yesAging Cell, 2012
SummaryReplicative senescence has fundamental implications on cell morphology, proliferation, and differentiation potential. Here, we describe a simple method to track long‐term culture based on continuous DNA‐methylation changes at six specific CpG sites.

VDLIN: A Deep Learning‐Based Platform for Methylcobalamin‐Inspired Immunomodulatory Compound Screening

open access: yesAdvanced Science, EarlyView.
Using the convolutional neural network model VDLIN, Co7 is identified as a promising therapeutic candidate. Co7 demonstrates distinct advantages over MCB by effectively balancing anti‐inflammatory and immune‐stimulatory functions, making it a potential novel approach for immune modulation.

Back-electron transfer suppresses the periodic length dependence of DNA-mediated charge transport across adenine tracts [PDF]

open access: yes, 2008
DNA-mediated charge transport (CT) is exquisitely sensitive to the integrity of the bridging π-stack and is characterized by a shallow distance dependence. These properties are obscured by poor coupling between the donor/acceptor pair and the DNA bridge,

T Cell Glycoengineering to Modulate Immune‐Tumor Crosstalk: A Universal Non‐Genetic Strategy for Enhanced Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study describes a T cell surface engineering strategy that integrates polymer materials with tumor immunology, aiming to achieve broad‐spectrum anti‐tumor applications of glycopolymer‐engineered T (G‐T) cells via non‐genetic modification. Glycopolymer engineering generally modulates immune‐tumor crosstalk through specific cell‐cell interactions ...

DNA methylation at the DAT promoter and risk for psychopathology. Intergenerational transmission between school-age youths and their parents in a community sample [PDF]

open access: yes, 2018
Background: The effect of gene polymorphisms and promoter methylation, associated with maladaptive developmental outcomes, vary depending on environmental factors (e.g., parental psychopathology).

CpG site-specific alteration of hydroxymethylcytosine to methylcytosine beyond DNA replication

open access: yesBiochemical and Biophysical Research Communications, 2012
Hydroxymethylcytosines (hmC), one of several reported cytosine modifications, was recently found to be enriched in embryonic stem cells and neuronal cells, and thought to play an important role in regulating gene expression and cell specification. However, unlike methylcytosines (mC), the fate of hmC beyond DNA replication is not well understood. Here,

Metformin Impairs Breast Cancer Growth through the Inhibition of PRMT6

open access: yesAdvanced Science, EarlyView.
Metformin has a biological activity against breast cancer. However, it is largely unknown about its precise therapeutic targets. Here, histone arginine methyltransferase PRMT6 is identified as a new anti‐cancer target for metformin. Metformin directly binds PRMT6 and inhibits its ability to catalyze histone H3R2 asymmetric dimethylation (H3R2me2a ...

Depletion of Sorcs3 Activates Totipotency in Mouse Embryonic Stem Cells by Modulating Key Signaling Pathways

open access: yesAdvanced Science, EarlyView.
In this article, Shuai and colleagues found that depletion of Sorcs3 could activate totipotency in mESCs, promising bidirectional differentiation potential to embryonic and extraembryonic lineages. The underlying mechanism might be activation of Tfap2c and repression of TGF‐β, PI3K‐AKT, and lysosome pathways.
