Abstract
Aim: The objective of this study was to analyze the effect of doxorubicin and cytarabine on biogenic amines and oxidative biomarkers in the brain of rats treated with oleic acid.
Methods: Thirty-six Wistar rats distributed in 6 groups, were treated as follows: group 1 (control), NaCl 0.9%; group 2 doxorubicin (1mg/kg); group 3 cytarabine (70mg /kg); group 4 oleic acid (1500μl/kg); group 5 doxorubicin + oleic acid; group 6 cytarabine + oleic acid. All compounds were administered intraperitoneally for 5 days. The Rats were sacrificed after receiving the last administration and their brains were dissected in cortex, hemispheres, and cerebellum/medulla oblongata. Blood samples were obtained on sacrifice to assess the levels of glucose and triglycerides. In each brain region, lipoperoxidation (TBARS), H2O2, Na+, K+ ATPase, glutathione (GSH), serotonin metabolites (5-HIAA) and dopamine were measured using validated methods.
Results: Cytarabine decreased the levels of dopamine, TBARS, GSH, H2O2 and ATPase in all regions. Doxorubicin combined with oleic acid increased the levels of GSH in cortex, and decreased ATPase in cerebellum/medulla oblongata.
Conclusion: These results suggest that the reduction of dopamine and oxidant effect during cytarabine treatment could result in brain injury but could be prevented by oleic acid supplementation.
Keywords: Brain, cytarabine, doxorubicin, oxidative damage, unsaturated fatty acid.

Discovery of Lead compounds targeting transcriptional regulation
Transcriptional regulation plays key physiological functions in body growth and development. Transcriptional dysregulation is one of the important biomarkers of tumor genesis and progression, which is involved in regulating tumor cell processes such as cell proliferation, differentiation, and apoptosis. Additionally, it plays a pivotal role in angiogenesis and promotes tumor ...read more
Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes that aid in stabilizing chromosomal makeup. The resynthesis of telomeres is supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no telomerase activity in human somatic cells, but the stem cells and germ cells undergo ...read more
