Abstract
Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths and the fifth most common cancer worldwide. Brown algae appeared to be a rich source of efficient and safe agents against many life-threatening diseases like cancer. Thus, the scope of this study was to investigate the therapeutic effects of Turbinaria ornata against experimentally induced HCC in a rat model. Accordingly, forty male albino rats were divided into four groups. HCC was induced by intraperitoneal injection with diethylnitrosamine (DENA) followed by carbon tetrachloride (CCL4). After four weeks of DENA + CCL4 injection and two weeks of treatment with Turbinaria ornata, rats were sacrificed to collect hepatic tissue and blood samples for histopathological observations and various biochemical markers such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alpha-fetoprotein (AFP), urea, creatinine, albumin (ALB), and alkaline phosphatase (ALP). Rats that were injected for four weeks with DENA + CCL4 showed a significant increase in AFP levels, transforming growth factor-beta (TGF-β) and tumor necrosis factor-alpha (TNF-α), as well as a high percentage of malignant changes in hepatic tissues. The extension of malignant changes in the rat liver tissues was markedly reduced using Turbinaria ornata, as the treatment displayed liver patterns similar to that of the normal control rats. Furthermore, rats with HCC fed with Turbinaria ornata extract for two weeks showed decreasing levels of TGF-β and TNF-α. These findings demonstrate that Turbinaria ornata supplement can prevent HCC development in hepatic rats; however, the exact mechanism requires further investigation.
期刊介绍：
The Journal of Molecular Histology publishes results of original research on the localization and expression of molecules in animal cells, tissues and organs. Coverage includes studies describing novel cellular or ultrastructural distributions of molecules which provide insight into biochemical or physiological function, development, histologic structure and disease processes.
Major research themes of particular interest include:
- Cell-Cell and Cell-Matrix Interactions;
- Connective Tissues;
- Development and Disease;
- Neuroscience.
Please note that the Journal of Molecular Histology does not consider manuscripts dealing with the application of immunological or other probes on non-standard laboratory animal models unless the results are clearly of significant and general biological importance.
The Journal of Molecular Histology publishes full-length original research papers, review articles, short communications and letters to the editors. All manuscripts are typically reviewed by two independent referees. The Journal of Molecular Histology is a continuation of The Histochemical Journal.
