Phage ϕC2 mediates transduction of Tn6215, encoding erythromycin resistance, between Clostridium difficile strains [PDF]

, 2013
UNLABELLED: In this work, we show that Clostridium difficile phage ϕC2 transduces erm(B), which confers erythromycin resistance, from a donor to a recipient strain at a frequency of 10(-6) per PFU.

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

Advanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

The bromodomain-containing protein Ibd1 links multiple chromatin related protein complexes to highly expressed genes in Tetrahymena thermophila

, 2018
Background: The chromatin remodelers of the SWI/SNF family are critical transcriptional regulators. Recognition of lysine acetylation through a bromodomain (BRD) component is key to SWI/SNF function; in most eukaryotes, this function is attributed to ...

The enzymes LSD1 and Set1A cooperate with the viral protein HBx to establish an active hepatitis B viral chromatin state [PDF]

, 2016
Indexación: Web of ScienceWith about 350 million people chronically infected around the world hepatitis B is a major health problem. Template for progeny HBV synthesis is the viral genome, organized as a minichromosome (cccDNA) inside the hepatocyte ...

DNMT2‐m5C‐ACLY Axis Promotes Lenvatinib Resistance in Hepatocellular Carcinoma Through Histone Acetylation‐Mediated Notch Pathway

Advanced Science, EarlyView.
Lenvatinib resistance poses a major challenge in advanced hepatocellular carcinoma (HCC). This study reveals that DNMT2 upregulation is a key driver, which stabilizes ACLY mRNA via m5C modification and activates the Notch signaling pathway. Crucially, combining ACLY inhibitors with lenvatinib overcomes resistance and suppresses tumors, offering a ...

Acetylation Regulates ACSL4 Degradation Through Chaperone‐Mediated Autophagy to Alleviate Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Intervertebral disc degeneration is triggered by ACSL4 accumulation‐mediated ferroptosis of nucleus pulposus cells due to CMA dysfunction. KAT2B promotes ACSL4 degradation via CMA through acetylation. AAV‐mediated LAMP2A delivery or engineered exosomes rescue nucleus pulposus cell senescence and disc degeneration.

NADH‐Reductive Stress Induced by Dihydrolipoamide Dehydrogenase Activation Contributes to Cuproptosis

Advanced Science, EarlyView.
This study demonstrates a cuproptosis mechanism involving nicotinamide adenine dinucleotide (NADH)‐reductive stress in neural cells. Copper activates dihydrolipoamide dehydrogenase under mitochondrial pH, accumulating NADH. Copper also induces mitochondrial permeability transition pore opening, facilitating NADH translocation to the cytosol and ...
