The first objective of the present study was to investigate the impact of ageing on arginase activity in tissues which exhibit age-related impairments in their function. The second objective was to determine whether l-arginine supplementation modulated the effect of ageing on arginase activity. The

The regulation of gene expression by glucocorticoids can be mediated either by the canonical mechanism that involves the interaction of the glucocorticoid receptor (GR), a transcription factor activated by the hormone, with glucocorticoid response element (Ye et al., 2007), or by the non-canonical m

Finally, the comparison between data obtained by antioxidant assays in in vitro cultured cells [11], [12] and in liposomes has disclosed the possibility to choose more confidently “the better phenolipid” of a series of fatty acids esters antioxidant derivatives. Looking at the physical parameters th

Although the interactions of PhLP with Gβγ and its other partners have been convincingly documented through in vitro studies, it is not clear how PhLP controls glucokinase signaling in vivo. C. elegans provides a powerful genetic model to analyze Phosducin function and study its interacting partners

Introduction Sustained over-activation of neurohormonal systems is a hallmark in the pathophysiology of cardiac dysfunction following myocardial infarction (MI) and heart failure (HF). Inhibitors of the renin-angiotensin pramipexole dihydrochloride system (RAAS) constitute cornerstones of pharma

Analysis of the enzyme activity, expressed as rate of product formation per unit serum volume (20μl), between the diagnostic groups revealed that ApB activity was significantly decreased in the patient group both at recruitment and after 13months when the substrate concentration used was 1.5mM (pR40

We have previously shown that the antinociceptive effect of tramadol, an analgesic that, like paracetamol is able to increase serotonin levels within CNS, is potentiated or antagonized respectively by a 5-HT1A/B nonspecific sonidegib blockade or activation (Rojas-Corrales et al., 2000). Moreover, it

Our in vitro data show that CyaA does not play a critical role in the bacterial adherence to mammalian cells. This observation is in contrast to previous studies that reported a role for CyaA in FHA-mediated adherence of B. pertussis bacteria to the respiratory epithelial Celastrol [37,38]. This dis

MicroRNA (miRNA) is an abundant group of small (22-nucleotide) noncoding RNA molecules that directly binds with 3′ untranslated region (UTR) of target messenger RNAs (mRNAs) to regulate gene expression, playing an important role in variety of biological processes including cell proliferation, apopto

Conclusion This is the first report to show that treatment of lung cancer cell lines, A549 and H1299, with ovatodiolid stimulates intracellular reactive oxygen species generation and induces DNA damage. Subsequently activates ATM/ATR and CHK1/2 signaling pathway, inhibits CDC25C and p21WAF1/CIP1,

Introduction Melatonin (N-acetyl-5-methoxytryptamine) is a neurohormone which is mainly secreted from the pineal gland. Melatonin is a highly conserved molecule present not only in vertebrates but also in nonvertebrates such as bacteria, protists, fungi, macroalgae, and plants (Cecon et al., 2017

ASK1 belongs to the family of MAPKKK. ASK1-mediated apoptosis is involved in the pathogenesis of several diseases such as I/R injury, infectious diseases and neurodegenerative disorders [33], [34], [35]. ASK1 can be activated through different mechanisms. One mechanism is that oxidative stress direc

We have shown that an extensive region in SERBP1 (amino acids 354 to 474, using co-ordinates based on the full-length isoform, Figs. 1a and 2) is necessary for it to interact with RACK1; since this region has substantial homology to the corresponding region of HABP1 (Fig. 3) it is a reasonable hypot
