Allium sativum aqueous extract does not have chemo-protective effect on etoposide induced therapy-related DNA damage leading to Acute Myeloid Leukemia in albino-wistar rats

Abstract

Background: Therapy-related acute myeloid leukemia (t-AML) is a well-recognized clinical syndrome occurring in a signif- icant fraction of patients who have undergone previous chemotherapy for a solid tumour.
 Objectives: We aim to evaluate the effect of aqueous extract of fresh Allium sativum cloves on haematological parameters, bone marrow and DNA of etoposide treated albino wistar rats. Decoction method was used to prepare plant extracts and the rats were weighed and divided into experimental and control groups. Blood and bone marrow sample were analysed and DNA fragment analysis was carried out.
 Results: There was progressive increase in the weight of animals that received distilled water only for the duration of the experiment while those that received etoposide only showed a sharp decrease in weight by the end of week 3. There was no significant difference in the mean of the haematological parameters in the test and control groups except for platelet count. The bone marrow smears showed no prevention of erythroblast fragmentation by the extract, in the same vein, DNA dam- age was not abated.
 Conclusion: Aqueous extract of fresh Allium sativum cloves may not be the option for the prevention of etoposide induced acute myeloid leukemia.
 Keywords: Allium sativum aqueous; chemo-protective effect; acute myeloid leukemia; albino-wistar rats.

Targeting AraC-Resistant Acute Myeloid Leukemia by Dual Inhibition of CDK9 and Bcl-2: A Systematic Review and Meta-Analysis

“…Among them, small-molecule inhibitor-targeted treatment is even more popular and highly concerned. Small molecule inhibitor-targeted treatment mainly suppresses cell growth, proliferation, and survival by targeting relevant cell signaling pathways (for example, kinase pathway, apoptosis pathway, DNA damage repair-related pathway) to achieve the effect of treating AML [ 44 – 47 ]. At present, the research of such new therapies has also achieved gratifying results.…”

GCMS fingerprints and phenolic extracts of Allium sativum inhibit key enzymes associated with type 2 diabetes

“…A. sativum has been demonstrated to be a complementary medicine for the management/treatment of disorders such as cardiovascular disease, 24 male infertility, 25 fungal disease, 26 and rheumatoid arthritis. 27 Some researched extracts of this herb include methanol extract 28 and aqueous extract, 29 but limited data are available regarding the antidiabetic potential of the phenolic extract of this herb. To this end, we investigated the antidiabetic potential of A. sativum through a combination of in vitro wet-lab assays and computational drug discovery.…”

Editorial: Infectious diseases and NCDs persist despite concerted effort

“…We have several oncology papers. First, Uganda authors 20 have written on ‘detecting subclinical anthracycline therapy related cardiac dysfunction’; while Ghanaian workers bring to us theirs on ‘awareness and knowledge about prostate cancer among male teachers.’ 21 Then we have several papers on potential anticancer activity of on selected herbs 22 , 23 ; followed by a case report 24 on ‘transient bone marrow hypoplasia preceding T-Cell acute lymphoblastic leukemia.’ We end this section on cancer with a molecular study on nucleophosmin 1(NPM1) gene in acute myeloid leukemia 25 .…”
