Study on the Screening of Anti‐Osteoporosis Components in Processed Epimedium‐Based on Spectrum‐Effect Analysis

Chemistry &Biodiversity, EarlyView.
ABSTRACT Epimedium (EP) is a traditional Chinese medicine that has been used to treat osteoporosis for several years, but its mechanism of action is unclear. We used ultrahigh‐performance liquid chromatography coupled with triple–quadrupole mass spectrometry (UPLC–QQQ–MS/MS) to detect the components of raw and processed EP samples.

Antinociceptive and Anti‐inflammatory Effect of Nicandrin B Isolated From Datura ferox in Zebrafish

Chemistry &Biodiversity, EarlyView.
ABSTRACT Nicandrin B (Nic B), a withanolide isolated from Datura ferox leaves, was investigated for its antinociceptive and anti‐inflammatory effects in adult zebrafish (Danio rerio). Animals treated with Nic B (4, 20, and 40 mg/kg) showed no toxicity and maintained normal locomotor activity.

Smooth microsomes. a trap for cholesteryl ester formed in hepatic microsomes.

Journal of Biological Chemistry, 1980
Acyl-CoA:cholesterol acyltransferase was found predominantly (85%) in RNA-rich microsomes, the rest being in RNA-poor and smooth microsomes. However, the esterified cholesterol concentration of smooth microsomes was 2-fold greater than that of RNA-rich microsomes, suggesting the possibility of an interaction between RNA-rich and smooth microsomes.

Toxic Evaluations of Calea phyllolepis Extracts Standardized on 6‐epi‐β‐Verbesinol Coumarate and Its In Silico Prediction of the Toxicity

Chemistry &Biodiversity, EarlyView.
In vivo and in silico toxicological effects of Calea phyllolepis extracts Standardized on 6‐epi‐β‐Verbesinol Coumarate. ABSTRACT Medicinal plants are traditionally used in folk medicine. Still, there is a misconception about the safety/efficacy of natural treatments, which results in few studies on the toxic, genotoxic, and mutagenic potential of ...

Induction of fibroblast senescence generates a non-fibrogenic myofibroblast phenotype that differentially impacts on cancer prognosis [PDF]

, 2016
Cancer-associated fibroblasts (CAF) remain a poorly characterized, heterogeneous cell population. Here we characterized two previously described tumor-promoting CAF sub-types, smooth muscle actin (SMA)-positive myofibroblasts and senescent fibroblasts ...

Development of Keap1‐Nrf2 Protein–Protein Interaction Inhibitor Activating Intracellular Nrf2 Based on the Naphthalene‐2‐acetamide Scaffold, and its Anti‐Inflammatory Effects

ChemMedChem, EarlyView.
Pyrrolidine‐type naphthalene‐2‐acetamide compound 5i inhibits Kelch‐like ECH‐associated protein 1 (Keap1)‐nuclear factor erythroid 2‐related factor 2 (Nrf2) protein–protein interaction by binding to the Keap1‐DC domain; it subsequently activates intracellular Nrf2 and induces Nrf2‐target genes.

Abnormal subcellular distribution of GLUT4 protein in obese and insulin-treated diabetic female dogs

Brazilian Journal of Medical and Biological Research, 2004
The GLUT4 transporter plays a key role in insulin-induced glucose uptake, which is impaired in insulin resistance. The objective of the present study was to investigate the tissue content and the subcellular distribution of GLUT4 protein in 4- to 12-year-
