  Cytochromes P450 (CYP 450) are a superfamily of hemoproteins containing a heme cofactor, which are widely distributed in animals, plants and microbes (Hannemann et al., 2007). CYP450 exhibits a variety of biological functions including biotransformation of drugs, detoxification of endogenous and xen

  Pyrazolopyrimidines are bioisostere of purine exhibit promising antitumor activity by competitively binding to the ATP active site of different kinase DCC-2036 synthesis [16,17]. Several compounds of this family were found to induce apoptosis and/or reduce cell proliferation in various solid tumour

  As previously stated, the most unexpected finding from this series of compounds was the identification of a dimethyl isoxazole side chain that gave dramatically improved binding over the parent compounds. Holding this piece of the molecule constant, a series of analogs were made to further understan

  To date, the role of CRF and CRF1+ neurons within the amygdala in the expression of anxiety-like behavior and conditioned fear, and the place where these cell populations fit into the fear-related microcircuitry already identified in the CeA, have not been fully characterized. Recent evidence suppor

  2021-02-04

  

  The enzyme cyclooxygenase (COX) or prostaglandin endoperoxide H synthase (PGHS) is the key enzyme in the conversion of arachidonic Nile Red (AA) into prostaglandins (PGs) [1]. In 1991, researchers found that there were two isoforms of this enzyme called COX-1 and COX-2 with independent genes and dif

  2021-02-04

  

  Abdominal aortic aneurysm (AAA) is considered a major health concern and is associated with extremely high rates of mortality in case of aortic rupture. The main pathophysiologic mechanisms leading to aortic dilation include the degradation of the extracellular matrix (ECM) components, such as colla

  In some cases, more than one CYP450 enzyme may be involved in the metabolism of a drug, and an Eadie–Hofstee plot is usually more reliable for assessing the involvement of multiple l-name (Bu, 2006). Therefore, we first plotted the Eadie–Hofstee curves and observed their shape to determine the kine

  DNA hypomethylation has been found in liver tumor and other tumors of humans, such as laryngeal cancer, 5-Formyl-CTP tumors, tongue squamous cell carcinoma and uterine leiomyomas [[20], [21], [22], [23], [24]]. Then, we mainly sought to confirm whether TCA could induce DNA hypomethylation in vitro a

  However, there are still some issues that remain poorly understood. For instance, how TGF-β modulates DDR2 expression and whether Smads participate in the regulation. How does DDR2 regulate the expression of PTHrP via Runx2? Is there any other kinase downstream of DDR2 participating in PTHrP regulat

  Recently, we have observed that pharmacological PPARα and PPARβ/δ activation regulates the expression of genes involved in FA metabolism such as FAT/CD36, CPT1, LCAD and MCAD in Sertoli cells. We have also observed that PPARβ/δ activation can simultaneously regulate the expression of the above-menti
