  The specific functions of ERs and AR underline their crucial roles during different phases of spermatogenesis. Their deregulation could affect numerous downstream targets, thereby, disrupting spermatogenesis and male fertility. Various studies have shown that estrogen-like chemicals in the environme

  Introduction Alzheimer's disease (AD) is a complex neurological disorder characterized by a progressive dementia resulting from synapse failure (Selkoe, 2002, Tanzi, 2005). The amyloid hypothesis maintains that the pivotal event in AD is the production of amyloid-β (Aβ) peptides following the prote

  Conflict of interest Introduction Colorectal cancer (CRC) is one of the major cause of tumor-related morbidity and mortality worldwide. Poor prognosis and consequences of its metastatic spread make CRC the second most common cause of cancer-related deaths in western countries [1]. Apart from o

  Ginsenosides are the major bioactive constituents of the Panax ginseng root, which contain many types of ginsenosides including Rb1, Rg1, Rc, and Rg3. The ginsenoside Rb1 appears to be the most abundant of the bioactive ginsenosides [15]. Rb1 exhibits antiinflammatory, anticarcinogenic, and antioxid

  Liaohe River situates in the southwestern part of Northeast China and flows through Liaoning Province. Due to the rapid urbanization and industrialization, Liaohe River has become one of the most polluted rivers in China. Multitudinous organic pollutants that can induce toxicity to organisms such as

  2024-08-06

  

  Since the cloning of ARs in the beginning of the 1990s, the efforts to characterize them have led to the accumulation of a substantial amount of experimental data. Decades of site-directed mutagenesis (SDM; Box 1) studies, in combination with pharmacological data and computational modeling, have pav

  A key step in the ADAR reaction is the formation of the adenosine covalent hydrate with a tetrahedral center at C6. The nucleoside analog 8-azanebularine (box in Fig. 6), with its relatively high propensity to form a covalent hydrate, is useful as an adenosine replacement in ADAR2 substrates to trap

  Using our infection assays, we also explored whether low-pH compartments were required for the entry of ZIKVs in mammalian cells. Lysosomotropic agents such as ammonium chloride, chloroquine and Bafilomycin A1, strongly inhibited the ability of ZIKVs to enter mammalian cells. Our results are in agre

  2024-08-05

  

  Another important question concerns the mechanism by which a polyubiquitinated substrate is released from the Cdc48 complex and passed on to downstream components, such as the proteasome. There are at least three proposed models. In the first, a ubiquitinated substrate is transferred by ubiquitin-bi

  Crystal structures were obtained of sulfonamide 18 and amide 19 as a derivative of amide 36 (Fig. 7A and B). The precise rotameric orientation of amide 36 was of significant interest to understand the compound's interaction with the protein. As it would be difficult to assign the rotomer of 36, the

  Circulating adrenal-derived stress hormones, epinephrine and corticosterone mediate their tissue effects through adrenergic (AR; α and β) and glucocorticoid (GR) receptors. AR are widely distributed throughout the body and although epinephrine is a prototypical agonist for all types of AR, the selec

  Derivatives of (+)-M100907 that possess either an alkyne or an azide have been synthesized. The most active enantiomer was obtained by resolution of a relatively early intermediate in the synthesis. The ability of these Brilliant Blue G to maintain 5-HTR antagonist properties as (+)-M100907 was demo
