Materials and methods Results Discussion GOS potently inhibited SRD5A1 in COS-1 cells (Fig. 4A) and rat Leydig cells (Fig. 4B), possibly attenuating testosterone activation into DHT. It has been reported that gossypol inhibited human SRD5A1 with IC50 of 7 × 10−6 M [28]. Interestingly, gossy

Despite low respiratory rates in citrus fruit, prolonged periods of storage may cause significant changes in the levels of organic acids (Echeverria and Valich, 1988). V-ATPase and V-PPase catalyze the electrogenic H+ translocation from the cytosol to the vacuolar lumen to generate an inside-acid pH

2019-11-12
COMT expression, protein level and activity are down regulated by E2. Using estrogen receptor (ER) positive MCF-7 cells, Xie et al. demonstrated an E2 dose dependent (1, 10 and 100 nM) decrease in S-COMT 1.3 kb mRNA that was maximum after 48 h (Xie et al., 1999). A similar decrease was not observed

Introduction Human cytomegalovirus (CMV) is a herpesvirus which has a ubiquitous and worldwide distribution, and is the most frequent cause of congenital infection (Kenneson and Cannon, 2007). The prevalence is around 0.5–1% of all live births and is the leading cause of sensorineural hearing loss

As a transcription factor, HOXA9 regulates multiple target genes related to cell growth, including BRCA1 [34], BCL-2 [35], c-MYB [36], IGF1 [37], PIM1 [38] and so on. In addition, HOXA9 is a member of both activating and repressive transcriptional regulatory complexes, along with cofactor and collab

The effect of ET-1 activity on the development of experimental pulmonary fibrosis has also been examined by other investigators. One study found that repeated administration of Bosentan, an ERA used to treat pulmonary arterial hypertension (PAH), significantly decreased bleomycin-induced pulmonary f

A previous study suggested that DARs and octopamine/tyramine receptors (OARs/TARs) have close pharmacological properties (Beggs et al., 2011). Their relationships were also supported by phylogenetic analyses (Balfanz et al., 2005, Hauser et al., 2008, Wu et al., 2014), indicating that some of DAR an

2019-11-11
Another mechanism underlying on the toxicity of dopaminergic neurons might be related to dopamine-dependent initial oxidative stress [60]. Dopamine orexin mediated by monoamine oxidase (MAO) can produce hydrogen peroxide as a by-product, and excess dopamine can undergo auto-oxidation to quinones or

The pyrrolo[2,1-][1,4]benzodiazepines (PBDs) are a family of antitumour antibiotics that includes the natural products anthramycin and DC-81. They exert their cytotoxicity by covalently bonding to the exocyclic C2–NH group of guanine residues in the minor groove of DNA through their N10–C11 imine fu

To evaluate the new quadrupolar CPA (qCPA) the pure fluid properties of CO2 are predicted both in the critical region and in the compressed liquid region. The model is furthermore applied for the prediction and correlation of binary mixtures with CO2 and n-alkanes, water, alcohols and a few quadrup

Introduction Determining how genes function together as biological systems is a defining challenge of the genomic era. While genome sequences reveal the DNA blueprint of organisms, deciphering how this blueprint leads to biological function is challenging due in large part to the complexity of prot
