Perspectives on natural compounds in chemoprevention and treatment of cancer: an update with new promising compounds.

Eur J Cancer 2021 Apr 14;149:165-183. Epub 2021 Apr 14.

Department of Pharmaceutical Sciences and Research, School of Pharmacy, Marshall University, Huntington, WV, 25701, USA. Electronic address:

Cancer is the second deadliest disease worldwide. Although recent advances applying precision treatments with targeted (molecular and immune) agents are promising, the histological and molecular heterogeneity of cancer cells and huge mutational burdens (intrinsic or acquired after therapy) leading to drug resistance and treatment failure are posing continuous challenges. These recent advances do not negate the need for alternative approaches such as chemoprevention, the pharmacological approach to reverse, suppress or prevent the initial phases of carcinogenesis or the progression of premalignant cells to invasive disease by using non-toxic agents.

Anti-carcinogenic effects of exercise-conditioned human serum: evidence, relevance and opportunities.

Eur J Appl Physiol 2021 Apr 17. Epub 2021 Apr 17.

School of Biomedical, Nutritional and Sport Sciences, Faculty of Medical Sciences, Newcastle University Centre for Cancer, Newcastle University, Newcastle upon Tyne, UK.

Regular physical activity reduces the risk of several site-specific cancers in humans and suppresses tumour growth in animal models. The mechanisms through which exercise reduces tumour growth remain incompletely understood, but an intriguing and accumulating body of evidence suggests that the incubation of cancer cells with post-exercise serum can have powerful effects on key hallmarks of cancer cell behaviour in vitro. This suggests that exercise can impact tumour biology through direct changes in circulating proteins, RNA molecules and metabolites. Read More

Institute of Experimental and Clinical Pharmacology, Faculty of Medicine, University Hospital of Schleswig-Holstein, Campus Kiel, Arnold Heller Strasse 3, 24105, Kiel, Germany.

The present study elucidates the neuroprotective mechanisms of the PPARγ (peroxisome proliferator-activated receptor γ) agonist pioglitazone in survival of ischemic neurons following middle cerebral artery occlusion with reperfusion (MCAO). Intracerebroventricular infusion of pioglitazone over 5 days before and 24 or 48 h after MCAO alleviated neurological impairments, inhibited apoptosis 24 h, and activated the PI3K/Akt pathway along with increased phosphorylation of Akt (ser473) and GSK-3β (ser9) in the peri-infarct cortical areas 48 h after MCAO. In primary cortical neurons, pioglitazone suppressed the glutamate-induced release of lactate dehydrogenase by a PPARγ-dependent mechanism. Read More
