Ellagic acid (EA) has been proposed as a promising candidate for therapeutic use in colon cancer. Investigation of the effectiveness of EA in a leptin-enriched model might have been given a little interest. Here in, we investigated the anti-tumor effect of EA in the presence of leptin to reflect on therapeutic use of EA in obesity-linked colon cancer. Proven effective in leptin-enriched microenvironment, EA inhibited cell proliferation of HCT-116 and CaCo-2 cell lines, modulated cell cycle, translocated Bax to the mitochondrial fraction of cells, activated caspase-8, and reduced PCNA expression. The current study findings cast a beam of light on the potential therapeutic use of EA in obesity-related colon carcinogenesis.
Background: Haematological malignancies are ranked as the highest in incidence. Adiponectin (ADIPOQ), the most abundant circulating adipocytokine, plays a major role in the regulation of insulin sensitivity, metabolism, and hematopoiesis. Various ADIPOQ gene polymorphisms are associated with an increased risk of different cancers. However, to the best of our knowledge, the association between ADIPOQ T45G (rs2241766) single nucleotide polymorphism (SNP) and leukemia is unknown. Aim: This study aimed to investigate the association between ADIPOQ (rs2241766) and the clinicopathological status of Egyptian leukemia patients. Materials and Methods: A case-control design was used, including 80 leukemia patients and 70 healthy controls. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for genotyping. Survival analysis and biochemical investigations including hematological and lipid profiles, liver and kidney functions in addition to anthropometric measurements were also determined. Results: A significant positive correlation between ADIPOQ gene T45G (rs2241766) SNP and leukemia incidence was detected. The G allele was more frequent in leukemia patients compared to the T allele. Kaplan-Meier analysis revealed that the SNP rs2241766was associated with the patient's event-free survival but not the overall survival. In addition, G carriers, hyperglycemia, and hyperuricemia patients had a significantly shorter median EFS compared with T carriers, normoglycaemia, and normoglycemia patients. Conclusion: The current study shows an association between the SNP (rs2241766) and leukemia incidence and prognosis in Egyptian patients. Furthermore, an association between the rs2241766 and high prevalence of hyperglycemia and dyslipidemia in the G allele carrier's leukemia patients was also evident.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
