Circadian rhythms and hormonal homeostasis: Pathophysiological implications [PDF]

, 2017
Over recent years, a deeper comprehension of the molecular mechanisms that control biological clocks and circadian rhythms has been achieved. In fact, many studies have contributed to unravelling the importance of the molecular clock for the regulation ...

Sirt1 and the Mitochondria

Molecules and Cells, 2016
Sirt1 is the most prominent and extensively studied member of sirtuins, the family of mammalian class III histone deacetylases heavily implicated in health span and longevity. Although primarily a nuclear protein, Sirt1's deacetylation of Peroxisome proliferator-activated receptor Gamma Coactivator-1α (PGC-1α) has been extensively implicated in ...

The Role of Extracellular Vesicles MicroRNAs in Sarcopenia: From Aging to Multi‐Morbidity

AGING MEDICINE, EarlyView.
Exosomes transporting miRNAs play a crucial bidirectional regulatory role in the process of sarcopenia, both in natural aging and under various pathological conditions. ABSTRACT Sarcopenia, defined as progressive loss of skeletal muscle mass and function, occurs during aging and has also been recognized for its detrimental effects in various disease ...

Glioma-induced SIRT1-dependent activation of hMOF histone H4 lysine 16 acetyltransferase in microglia promotes a tumor supporting phenotype

OncoImmunology, 2018
High-grade gliomas are malignant aggressive primary brain tumors with limited therapeutic options, and dismal prognosis for patients. Microglia, the resident immune cells of the brain, are recruited and reprogrammed into tumor-supporting cells by glioma ...

Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

Animal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

An ultra‐processed food‐based cafeteria diet induces obesity, metabolic dysfunction, and tissue‐specific gene dysregulation in C57BL/6 mice

Animal Models and Experimental Medicine, EarlyView.
This schematic figure illustrates the experimental design and key findings of the study. Forty male C57BL/6 mice were assigned to either a standard diet control group or a cafeteria diet (CAFD) group for 16 weeks. CAFD induces obesity, insulin resistance (HOMA‐IR), hepatic steatosis, and dysregulation of a number of genes in visceral and subcutaneous ...

The HCMV‐encoded miR‐UL36‐3p promotes angiogenesis of endothelial cells by downregulating FOXO3

Animal Models and Experimental Medicine, EarlyView.
This illustration shows the role of hcmv‐miR‐UL36‐3p in endothelial cell angiogenesis. During productive infection, endothelial cells express HCMV‐encoded miRNAs. Viral hcmv‐miR‐UL36‐3p promotes endothelial cell proliferation, migration, and capillary tube formation by directly targeting and downregulating FOXO3. The pro‐angiogenic activity of hcmv‐miR‐
