Biosynthesis of H2S and Siderophores Targeting Gram‐Negative Bacterial Resistance to Reactive Oxygen Species

open access: yesAdvanced Science, Volume 12, Issue 45, December 4, 2025.
Discover how Gram‐negative bacteria develop resistance to reactive oxygen species, and how scientists aim to overcome this challenge. Abstract Reactive oxygen species (ROS) are a promising alternative bactericide. However, it is questioned that bacteria can potentially develop resistance to ROS, similar to their resistance against antibiotics and ...

Methylation status of Dnmt1 promoter depends on poly(ADP-ribosy)lation [PDF]

open access: yes, 2007
Research is focused on CpG islands and on the mechanism that poly(ADP-ribosyl)ation uses to defend the unmethylated state of these important DNA sequences which are located in the promoter regions of the housekeeping genes having a role of transcription ...

Epigenetic dynamics in gastric cancer precancerous lesions: From molecular mechanisms to precision risk stratification

open access: yesClinical and Translational Discovery, Volume 5, Issue 6, December 2025.
Gastric precancerous lesions undergo dynamic epigenetic alterations—including DNA methylation, 5‐hydroxymethylcytosine, non‐coding RNAs, and RNA editing—throughout the Correa's cascade. The integration of these multi‐omics epigenetic signatures facilitates non‐invasive risk stratification, which guides personalised surveillance strategy and targeted ...

Alteration of Epigenetic Regulation by Long Noncoding RNAs in Cancer [PDF]

open access: yes, 2018
Long noncoding RNAs (lncRNAs) are important regulators of the epigenetic status of the human genome. Besides their participation to normal physiology, lncRNA expression and function have been already associated to many diseases, including cancer.

Epigenetic regulation modulates seasonal temperature‐dependent growth of soybean in southern China

open access: yesPlant Biotechnology Journal, Volume 23, Issue 10, Page 4580-4601, October 2025.
Summary Epigenetic variations, including DNA methylation and small RNAs, are crucial for plant stress adaptation. However, their association with soybean adaptation to natural environments remains unclear. Through multi‐omics analyses, we investigate soybeans from distinct geographical regions (Northern China: HH43, Southern China: HX3, and Wm82) and ...

Evolutionary Origins of Two-Barrel RNA Polymerases and Site-Specific Transcription Initiation [PDF]

open access: yes, 2017
Evolutionary-related multisubunit RNA polymerases (RNAPs) carry out RNA synthesis in all domains life. Although their catalytic cores and fundamental mechanisms of transcription elongation are conserved, the initiation stage of the transcription cycle ...

Characterization of B Cell Responses in Rainbow Trout (Oncorhynchus Mykiss) Affected by Red Mark Syndrome

open access: yesAdvanced Science, Volume 12, Issue 35, September 18, 2025.
This study extensively characterizes the B cell response of rainbow trout (Oncorhynchus mykiss) in response to red mark syndrome (RMS). This disease, suspected to be caused by a Midichloria‐like organism (MLO), induces skin lesions in the infected animals, characterized by a massive influx of IgM+ B cells.

The RNA-binding protein LARP1 is a post-transcriptional regulator of survival and tumorigenesis in ovarian cancer [PDF]

open access: yes, 2015
RNA-binding proteins (RBPs) are increasingly identified as post-transcriptional drivers of cancer progression. The RBP LARP1 is an mRNA stability regulator, and elevated expression of the protein in hepatocellular and lung cancers is correlated with ...
