  Inflammations lead to the perturbation of aromatase enzyme [112], which normally is responsible for a broad array of critical functions. Chemotherapy targets this enzyme, so this treatment option is never side-effect-free and not fully-effective. Therefore, the mankind should be careful so as not to

  Current limitations and future directions There are several limitations associated with PET imaging of aromatase using carbon-11 labeled aromatase inhibitors. Due to the very short half-life of carbon 11 (20min), PET studies with currently available, validated tracers can only be performed in med

  2024-03-21

  

  ARG I is one of the most important mammalian enzymes responsible for nitrogen metabolism since it comprises the main route for the elimination of excess nitrogen resulting from amino 366 2 mg and nucleotide metabolism [18]. ARG I deficiency leads to hyperargininemia, characterized by progressive neu

  2024-03-20

  

  It has been proposed that angiotensin II (Ang II) may upregulate COX-2 expression and the subsequent vasoconstrictor prostanoids production through the activation of AT-1 receptors in vascular smooth muscle cells (Hu et al., 2002). Additionally, this peptide is also able to stimulate the generation

  Although mature fibrils formed from Aβ A-1155463 have long been thought to be the main neurodegenerative agents in AD, recent evidence suggests that soluble multimers of these pathogenic proteins, referred to here as “oligomers,” may initiate the synaptic and neuronal dysfunction associated with AD

  Exposure to B[a]P is an epidemiologically proven cause of lung cancer (Hecht, 2003; Rojas et al., 2004; Alexandrov et al., 2010), and the formation of B[a]PDE-N2-dG adducts is considered to be the critical event in lung tumorigenesis by B[a]P. On the other hand, there is evidence suggesting that the

  Protein blast analysis of the sequence of globin-B with those of other mineralocorticoid receptor suggests that the globin-B domain in the HemAC-Lm displays only 6% identity and 34% similarity with that of cytoglobin/neuroglobin (Fig. 2). Furthermore, SWISS-MODEL protein modeling also predicts that

  In summary, we suggest that both cofilin and gelsolin are essential factors that regulate sperm capacitation and the acrosomal exocytosis by modulating actin. The relationships between activation/inactivation of cofilin and gelsolin suggest that inhibition of cofilin is important for allowing F-acti

  A combination of factors might, however, account for the low rate of success of drug development for neuropsychiatric disorders. First, in most neuropsychiatric disorders, the symptomatology is heterogeneous and the neurobiology remains poorly understood, making therapeutic targets difficult to iden

  Introduction Dementia is a common disease in the elderly, and a significant source of disability, healthcare spending, and long-term care admissions. There is evidence to suggest that testosterone plays a role in cognitive functioning, and lower serum levels correlate with higher amyloid deposits (

  Introduction 5-hydroxytryptamine (5-HT) is found throughout the body and influences smooth muscle activity in various tissues including the intestine, vasculature and urinary ephrin receptor (Kim and Camilleri, 2000, Klarskov and Horby-Petersen, 1986, Mohammad-Zadeh et al., 2008).

  ACL Regulation and Role in Lipid Metabolism ACL is a ubiquitous enzyme at the nexus of nutrient catabolism and synthesis of cholesterol and fatty acids. In mammals, it is highly expressed in lipogenic tissues including adipose, liver, and lactating mammary glands [9]. In the presence of ATP and C

  Recent studies have demonstrated that in response to IR, hundreds of substrates are phosphorylated in an ATM-dependent manner, clearly demonstrating the complexity of the ATM-mediated DDR pathways (Matsuoka et al., 2007, Bennetzen et al., 2010, Bensimon et al., 2010).

  Aromatase: the key enzyme for estrogen formation in adipose tissue Estrogens are synthesized from androgens by aromatase, a member of the cytochrome P450 superfamily, which is the rate-limiting enzyme in estrogen biosynthesis (Santen et al, 2009, Simpson et al, 1994). At the cellular level, aroma
