Interplay of gene expression noise and ultrasensitive dynamics affects bacterial operon organization.

PLoS Computational Biology, 2012
Bacterial chromosomes are organized into polycistronic cotranscribed operons, but the evolutionary pressures maintaining them are unclear. We hypothesized that operons alter gene expression noise characteristics, resulting in selection for or against ...

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.

Roadmap to Nanomedical Applications: Nanotoxicology and In Vitro Guidelines for Lanthanide‐Doped Luminescence Nanothermometers

Advanced NanoBiomed Research, EarlyView.
Lanthanide‐based luminescence nanothermometry holds multifaceted potential for nanomedical applications, yet despite significant research advances, clinical translation of the engineered nanomaterials is still controversial and widely disputed. This is related to crucial nanotoxicological aspects that must be addressed at the preclinical level ...

Emergence of Staphylococcus aureus Resistance to Antimicrobial Peptides Nisin, NZ2114 and Bacitracin Involves Multiple Phenotypic Changes

Animal Research and One Health, EarlyView.
The AMP‐induced mutant Staphylococcus aureus strain nzR showed increased resistance, five gene mutations, and decreased surface anion levels. AMPs affect the NDH‐2 protein encoded by ndh gene inhibiting the growth of S. aureus. The deletion of the ndh gene promotes the development of AMPs resistance.

Bacterial Evolution: Chromosome Arithmetic and Geometry [PDF]

Current Biology, 2002
Recent sequencing projects have characterized bacterial genomes that are organized onto elements of various sizes, shapes and numbers. Aside from its biological relevance and curiosity, this diversity calls into question the way that we define bacterial chromosomes.

Dietary supplement of sodium butyrate improves the growth performance and intestinal health by targeting Wnt/β‐catenin signaling pathway in rabbits

Animal Research and One Health, EarlyView.
Dietary supplement of sodium butyrate, may relate to regulating intestinal health and thus the growth performance and meat quality of rabbits by regulating the continuous process of promoting the periodic cycle of cecal epithelial cells. Abstract Supplementation of sodium butyrate (SB) has been proved to be beneficial for improving the growth ...

Construction and Characterization of Novel Shuttle Expression Vectors for Actinobacillus succinogenes

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Actinobacillus succinogenes is a ruminal microorganism of biotechnological importance due to its capacity to produce succinic acid at high yields. Despite the scientific interest in this organism, molecular vehicles for the transfer and expression of genetic material are limited compared to the existing demand.

Compact Origins and Where to Find Them: ORC's Guide to Genome‐Wide Licensing

BioEssays, EarlyView.
Origin licensing is a key requirement for any eukaryotic cell to initiate DNA replication in S‐phase. Here, we review the most recent findings in the orchestrated action of the origin recognition complex (ORC) to sequentially load two MCM2‐7 helicases onto DNA with a focus on origin architecture and sequencing‐based methods.

Bacterial Chromosome Structure and Function

Biophysical Journal, 2012
We previously showed that the transcription profile of the E. coli chromosome is dictated by its structure. We proposed that the chromosome has defined structures which change the transcriptability of the constituent promoters. We are exploring to understand the structure of the E.

Improving trans‐cinnamic acid production in a model cyanobacterium

Biotechnology Progress, Volume 41, Issue 2, March/April 2025.
Abstract trans‐Cinnamic acid (tCA) is a precursor in the synthesis of many high‐value compounds with bio‐active qualities useful in applications like medicine, polymers, and cosmetics. Currently tCA is produced by industrial chemical synthesis from fossil fuels or cost‐prohibitive isolation from terrestrial plants.
