The Influence of Probiotics in Reducing Cisplatin-Induced Toxicity in Zebrafish (Danio rerio).

In this work, the effects of probiotic supplementation on cisplatin toxicity in zebrafish (Danio rerio) were examined. For this study, adult female zebrafish were given cisplatin (G2), the probiotic, Bacillus megaterium (G3), and cisplatin+B. megaterium (G4) for 30 days, in addition to the control (G1). In order to investigate changes in antioxidative enzymes, ROS production, and histological changes after treatment, the intestines and ovaries were excised. The levels of lipid peroxidation, glutathione peroxidase, glutathione reductase, catalase, and superoxide dismutase were found to be significantly higher in the cisplatin group than in the control group in both the intestine and the ovaries. Administration of the probiotic and cisplatin effectively reversed this damage. Histopathological analyses showed that the cisplatin group had much more damage than the control group and that probiotic+cisplatin treatment significantly cured these damages. It opens the door to probiotics being combined with cancer-related drugs, which may be a more efficient approach for minimizing side effects. The underlying molecular mechanisms of probiotics must be further investigated.

Role of probiotics in the management of cervical cancer: An update.

Studies have extensively investigated a variety of health benefits associated with probiotic supplements, which often contain live microorganisms. The effect of probiotic supplements on cancer prevention and on chemotherapy effectiveness and toxicity are major areas that researchers have focused on. Recently, several researchers have concentrated on assessing the efficacy of probiotics in the treatment of cervical cancer, a leading malignancy in gynecology worldwide, especially in developing countries. To date, numerous clinical studies have demonstrated the efficacy of probiotics in preventing cervical cancer, but their dosages, bacterial strains, and duration of therapy are somewhat inconsistent. In this review, we have systematically updated the role of probiotics in cervical cancer management.

Multifarious Beneficial Effect of Nonessential Amino Acid, Glycine: A Review.

Glycine is most important and simple, nonessential amino acid in humans, animals, and many mammals. Generally, glycine is synthesized from choline, serine, hydroxyproline, and threonine through interorgan metabolism in which kidneys and liver are the primarily involved. Generally in common feeding conditions, glycine is not sufficiently synthesized in humans, animals, and birds. Glycine acts as precursor for several key metabolites of low molecular weight such as creatine, glutathione, haem, purines, and porphyrins. Glycine is very effective in improving the health and supports the growth and well-being of humans and animals. There are overwhelming reports supporting the role of supplementary glycine in prevention of many diseases and disorders including cancer. Dietary supplementation of proper dose of glycine is effectual in treating metabolic disorders in patients with cardiovascular diseases, several inflammatory diseases, obesity, cancers, and diabetes. Glycine also has the property to enhance the quality of sleep and neurological functions. In this review we will focus on the metabolism of glycine in humans and animals and the recent findings and advances about the beneficial effects and protection of glycine in different disease states.
