Teamwork of clustered low-affinity κB sites and accessory factors regulates transcriptional strength of NF-κB RelA dimers

Nucleic Acids Research
Abstract Non-consensus binding sites of transcription factors (TFs) are often observed within the regulatory elements of genes; however, their effect on transcriptional strength is unclear. Within the promoters and enhancers of NF-κB-responsive genes, we identified clusters of non-consensus κB DNA sites, many exhibiting low affinity for ...

The stringent response regulates the poly-β-hydroxybutyrate (PHB) synthesis in Azotobacter vinelandii.

PLoS ONE
The stringent response exerted by (p)ppGpp and RNA-polymerase binding protein DksA regulates gene expression in diverse bacterial species. To control gene expression (p)ppGpp, synthesized by enzymes RelA and SpoT, interacts with two sites within the RNA ...

Ubiquitin and ubiquitin‐like modifications in the endoplasmic reticulum stress response

The FEBS Journal, EarlyView.
Endoplasmic reticulum (ER) stress activates various proteostasis control processes, including the unfolded protein response, ribosome‐associated quality control, and ER‐associated degradation. Ubiquitin and ubiquitin‐like modifications dynamically regulate these processes to determine cell fate, promoting adaptation or inducing cell death.

Circulating granulocyte colony‐stimulating factor as a sex‐unbiased global marker of lung and colorectal cancer cachexia pre‐clinical models

Experimental Physiology, EarlyView.
Abstract Cancer cachexia, affecting up to 80% of patients with advanced cancer, is characterized by metabolic and inflammatory dysregulation driven by tumour‐ and host‐derived factors. Although cytokines are central to cachexia pathogenesis, their circulating profiles and transcriptional relevance across models and sexes remain incompletely defined. We

NF-κB RelA is a cell-intrinsic metabolic checkpoint restricting glycolysis

Cell & Bioscience
An intrinsic link between metabolism and function in immune cells, and in particular macrophages, has been well established recently. However, the molecular mechanisms controlling the metabolic switch in these sentinel cells for their integral roles in ...

Extracellular high mobility group box 1 as a UV‐induced alarmin driving cutaneous inflammation and photoaging via TLR4 signaling

Journal of Cell Communication and Signaling, Volume 20, Issue 3, September 2026.
UV irradiation triggers the active release of HMGB1 from skin cell nuclei into the extracellular space. Extracellular HMGB1 binds TLR4 receptors on neighboring cells, initiating a signaling cascade that upregulates proinflammatory cytokines (IL‐1β, IL‐6, IL‐8, and TNF‐α). This chronic inflammatory state drives neutrophil infiltration and collagen fiber

Decoding the Heterogeneity of Diffuse Large B‐Cell Lymphomas: A Comprehensive Genetic, Transcriptomic, and Phenotypic Profiling of B‐Cell Lymphoma Cell Lines

Hematological Oncology, Volume 44, Issue 5, September 2026.
ABSTRACT Diffuse large B‐cell lymphoma (DLBCL) is the most prevalent form of non‐Hodgkin lymphoma, exhibiting significant molecular and clinical heterogeneity. Advances in classification integrating phenotypic, genetic, and transcriptomic features have improved diagnosis and prognosis.

Immunomodulation of the Prostate Tumor Microenvironment Following Inorganic Arsenic Exposure

Journal of Applied Toxicology, Volume 46, Issue 9, Page 3274-3287, September 2026.
ABSTRACT The tumor microenvironment (TME) influences prostate cancer (PCa) progression through stromal and immune interactions. Adipose‐derived mesenchymal stromal cells (ASCs) modulate immune tone, while inorganic arsenic (iAs), a widespread toxicant, is linked to immune suppression and carcinogenesis.

Immunomodulatory and Cytotoxic Properties of Enniatin B1 in Porcine Alveolar Macrophages

Journal of Applied Toxicology, Volume 46, Issue 9, Page 3220-3231, September 2026.
ABSTRACT This study investigates the immunomodulatory effects of Enniatin B1 (ENNB1), an emerging mycotoxin, on porcine alveolar macrophages (PAMs), a species‐specific model relevant to human innate immunity. PAMs were exposed to increasing ENNB1 concentrations (0.5–6 μM) over 6, 24, and 48 h.

Investigating the Impact of Caftaric Acid and Chicoric Acid From Echinacea Purpurea on NF‐κB p65 (pS529) Expression in THP‐1 Cells

Phytochemicals in Food and Medicine, Volume 1, Issue 3, September 2026.
Chicoric acid (A) and caftaric acid (B), active components of Echinacea purpurea, increase phosphorylation of NF‑κB p65 (Ser529). These findings indicate that both compounds can modulate immune responses through regulation of NF‑κB signalling, supporting their potential immunomodulatory roles.
