OBJECTIVE: Among other types of cancerous lesions, lung cancer is one of the prevalent causes of death. Trigonelline is a plant alkaloid, a significant constituent in coffee, and has shown health benefits in several disorders. The present study aims to investigate the potential therapeutic role of trigonelline in lung cancer. MATERIALS AND METHODS: Seventy-five BALB/C mice were assigned to five groups and treated for 150 days as follows (1): normal control group; (2) trigonelline only (50 mg/kg/ P.O) daily for the last thirty days; (3) urethane (1.5 g/kg B.w/i.p) at day one and sixty; (4) urethane and carboplatin (15 mg/kg i.p) for the last thirty days; and (5) urethane and trigonelline for the last thirty days. Tumor size was measured while blood and lung were collected for biochemical, western blotting analysis, and histological examinations. RESULTS: Urethane demonstrated significant changes in all biochemical and molecular parameters and histological examinations. In animals pretreated with urethane, trigonelline significantly reduced tumor size and restored Nrf2, NF-кB p65, Bcl-2, Cyclin D1, ICAM-1, and MMP-2, along with improving cGMP and active caspase three and refining histological architectures. CONCLUSIONS: Nrf2 signaling may be a promising therapeutic target for adenocarcinoma protection or management. Due to its multiple therapeutic effects on Nrf2, cyclin D1, NF-кB pathways, and the BAX/Bcl2 axis, trigonelline significantly induced cell cycle arrest and apoptosis. [ABSTRACT FROM AUTHOR]

Aims: Statins are the most widely used to lower elevated low-density lipoprotein levels and preventing cardiovascular diseases in humans. However, about 20% of patients treated with this medication suffer from statin-related myalgia. To this end, this study investigated the potential effect of nano-particulate formulation in alleviating the muscles and liver damage either alone or when co-administered with nano coenzyme Q10 and nano vitamin E., Materials and Methods: Male Wistar rats were fed normal diet or high-fat diet for 12 weeks, following which rats were treated with either (i) atorvastatin (5 or 20 mg/kg/day, p.o.) or (ii) atorvastatin with CoQ10 (10 mg/kg/day, p.o.) (iii) and/or vitamin E (30 mg/kg/day, p.o.) in free particle or nanoparticle forms for another 4 weeks. In all rats, serum total cholesterol (CH), triglycerides (TGs), low (LDL) and high (HDL) density lipoproteins, alanine (ALT) and aspartate (AST) transaminases, alkaline phosphatase (ALP), creatine kinase (CK), albumin (ALB), as well as hepatic malondialdehyde (MDA) and antioxidants "reduced glutathione (GSH) and superoxide dismutase (SOD)" were measured. Additionally quadriceps muscles and liver tissues were used for histopathological examination., Key Findings: The antihyperlipidemic effect of statins was not altered when formulated as nanoparticles; albeit the former showed a prominent reduction in the liver and muscle enzymes and histopathological alterations together with a marked decline in the oxidative stress as compared to the free particulate form. These results were augmented when atorvastatin was combined with CoQ10 and/or Vit.E., Significance: Nanoparticulate formulation alleviated the statins induced liver and muscle damage especially when combined with CoQ10 and/or Vit.E., (Copyright © 2018 Elsevier Inc.

Free 125I-labeled ovine prolactin can be separated from detergent-solubilized prolactin-receptor complex by filtration on triacetate membrane filters pretreated with polyethyleneimine. Up to 98% of the total 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate solubilized prolactin-receptor complexes from rat liver bound to polyethyleneimine-treated membranes. This simple and rapid technique can be used to quantitate solubilized prolactin-receptor complexes.
