Effect of Age and Lipoperoxidation in Rat and Human Adipose Tissue-Derived Stem Cells
(Hindawi, 2020)
A wide range of clinical applications in regenerative medicine were opened decades ago with the discovery of adult stem cells. Highly promising adult stem cells are mesenchymal stem/stromal cells derived from adipose tissue ...

In vitro and in Vivo Protection by Melatonin Against the Decline of Elongation Factor-2 Caused by Lipid Peroxidation: Preservation of Protein Synthesis
(Wiley-Blackwell, 2012)
As organisms age, a considerable decrease in protein synthesis takes place in all tissues. Among the possible causes of the decline of translation in old animals are the modifications of elongation factor-2 (eEF- 2). eEF-2 ...

Neuroinflammation alters cellular proteostasis by producing endoplasmic reticulum stress, autophagy activation and disrupting ERAD activation
(Nature Publishing Group, 2017)
Proteostasis alteration and neuroinflammation are typical features of normal aging. We have previously shown that neuroinflammation alters cellular proteostasis through immunoproteasome induction, leading to a transient ...

VCAM-1 targeted magnetic resonance imaging enables detection of brain micrometastases from different primary tumours
(American Association for Cancer Research, 2019)
Purpose: A major issue for the effective treatment of brain metastasis is the late stage of diagnosis with existing clinical tools. The aim of this study was to evaluate the potential of vascular cell adhesion molecule 1 ...

The combined partial knockdown of CBS and MPST genes induces inflammation, impairs adipocyte function-related gene expression and disrupts protein persulfidation in human adipocytes
(MDPI, 2022)
Recent studies in mice and humans demonstrated the relevance of H2S synthesising enzymes, such as CTH, CBS, and MPST, in the physiology of adipose tissue and the differentiation of preadipocyte into adipocytes. Here, our ...

Glioma-induced inhibition of caspase-3 in microglia promotes a tumor-supportive phenotype
(Springer Nature, 2016-10-19)
Glioma cells recruit and exploit microglia (the resident immune cells of the brain) for their proliferation and invasion ability. The underlying molecular mechanism used by glioma cells to transform microglia into a ...

Cyclic multiplex fluorescent immunohistochemistry and machine learning reveal distinct states of astrocytes and microglia in normal aging and Alzheimer’s disease
(BMC, 2022)
Background Astrocytes and microglia react to Aβ plaques, neurofibrillary tangles, and neurodegeneration in the Alzheimer’s disease (AD) brain. Single-nuclei and single-cell RNA-seq have revealed multiple states or ...

Pre-fermentative addition of an enzymatic grape seed hydrolysate in warm climate winemaking. Effect on the differential colorimetry, copigmentation and polyphenolic profiles
(Elsevier, 2016-10-15)
The effect of adding an enzymatic hydrolysate of grape seeds (EH-GS) during Syrah wine fermentation in a warm climate has been evaluated. We focused on the polyphenolic composition as well as the application of differential ...

Transcription of Liver X Receptor Is Down-Regulated by 15-Deoxy-Δ12,14-Prostaglandin J2 through Oxidative Stress in Human Neutrophils
(Public Library of Science, 2012)
Liver X receptors (LXRs) are ligand-activated transcription factors of the nuclear receptor superfamily. They play important roles in controlling cholesterol homeostasis and as regulators of inflammatory gene expression ...

Dendritic cells as a therapeutic strategy in acute myeloid leukemia: vaccines
(MDPI, 2024-02)
Dendritic cells (DCs) serve as professional antigen-presenting cells (APC) bridging innate and adaptive immunity, playing an essential role in triggering specific cellular and humoral responses against tumor and infectious ...
