KU80 suppresses endonuclease G activity to preserve genomic integrity

open access: yesThe FEBS Journal, EarlyView.
Under normal conditions, EndoG remains restricted to mitochondria and the genome remains intact. When KU80 is absent, EndoG translocates into the nucleus, where it promotes DNA fragmentation and genomic instability. Thus, this work highlights the importance of KU80 in tightly controlling EndoG localization to preserve genome stability.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

open access: yesThe FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

Identification of natural compound inhibitors for multidrug efflux pumps of Escherichia coli and Pseudomonas aeruginosa using in silico high-throughput virtual screening and in vitro validation.

open access: yesPLoS ONE, 2014
Pseudomonas aeruginosa and Escherichia coli are resistant to wide range of antibiotics rendering the treatment of infections very difficult. A main mechanism attributed to the resistance is the function of efflux pumps.

Astrocytic connexin43 phosphorylation contributes to seizure susceptibility after mild traumatic brain injury

open access: yesThe FEBS Journal, EarlyView.
Astrocytic gap junctions formed by connexin43 (Cx43) help maintain brain homeostasis. After mild traumatic brain injury (TBI), total cortical Cx43 increases and redistributes toward a soluble, non‐junctional pool with elevated hemichannel activity and increased phosphorylation at serine 368 (pCx43S368).

Propentofylline reduces glial scar development following gliotoxic damage in the rat brainstem

open access: yesArquivos de Neuro-Psiquiatria
Propentofylline is a xanthine derivative that depresses activation of glial cells, whose responses contribute to neural tissue damage during inflammation.

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

open access: yesInsect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Outbreaks of Granulomatous Disease Associated With Vibrio harveyi Infection in Grouper (Epinephelus fuscoguttatus × E. lanceolatus) Aquaculture in Taiwan

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Between 2015 and 2024, outbreaks of muscular and visceral granulomatous disease, resulting in moderate‐to‐severe mortality in farmed groupers, occurred in southern Taiwan. Initially, affected groupers were screened for granuloma‐associated pathogens, including Mycobacterium spp., Nocardia spp., Photobacterium damselae and Edwardsiella spp ...

Isolation and Identification of Erysipelothrix sp. in Hybrid Grouper (Epinephelus fuscoguttatus × E. lanceolatus) in Taiwan

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT In February 2025, a mortality event of unknown aetiology occurred at a hybrid grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) aquaculture farm in southern Taiwan, with sporadic daily deaths persisting for a month. Four moribund groupers were collected over three sampling intervals for diagnostic investigation.
