Abstract Background: Histone modifications play a crucial role in chromatin structure. Among enzymes, which regulate these processes, histone deacetylases (HDACs) can remove acetyl groups from histone tails, thus increasing their interaction with DNA and leading to chromatin condensation. 5-Aza-2′-deoxycytidine (AZad) or Decitabine is a potent hypomethylating agent that incorporates into DNA and traps DNA methyltransferase in the form of a covalent protein–DNA adduct. Azad, not only change the gene expression through demethylation of the gene's promoter, but it also can change gene expression independently from DNA demethylation. So, the present study was to distinguish whether AZad in addition to inhibitory effects on DNA methyltransferase, can change HDAC3 and HDAC7 mRNA expression in NALM-6, HL-60 cancer cell lines. Methods: HL-60, NALM-6 and normal cells were cultured, and the treatment dose of the AZad was obtained (1µM) by the MTT test. Finally, HDAC3 and HDAC7 mRNA expression were measured by Real Time PCR in HL-60 and NALM-6 cancerous cells before and after treatment. In addition, HDAC3 and HDAC7 mRNA expression in un-treated HL-60 and NALM-6 cancerous cells were compared to the normal cells. Results: Our result revealed that expression of HDAC3 and HDAC7, in HL-60 and NALM-6 cells increases as compared to normal cells. After treatment of HL-60 and NALM-6 cells with AZad, HDAC3 and HDAC7 mRNA expression were decreased significantly. Conclusions: Our data showed, the effects of AZad are not limited to direct hypomethylation of DNMTs but it can indirectly affect other epigenetic factors, such as HDACs activity, through converging pathways.

Colorectal cancer is the second most frequently diagnosed cancer worldwide. Conventional diagnostics methods of colorectal cancer, can detect it in advanced stage. Spectroscopic methods, including Raman spectroscopy and imaging, are becoming more and more popular in medical applications, and allow fast, precise and unambiguous differentiation of healthy and cancerous samples. the most important advantage of Raman spectroscopy is ability to identify biomarkers that help in differentiation of healthy and cancerous cells based on biochemistry of sample and spectra typical for: lipids, proteins, DNA. The aim of the study was to evaluate the biochemical and structural features of human colon cell lines based on Raman spectroscopy and imaging: normal cells CCD-18 Co, normal cells CCD-18 Co under oxidative stress conditions, normal cells CCD-18 Co at first treated by using tert-Butyl hydroperoxide and then supplemented by vitamin C in high concentration to show the protective role of vitamin C in micromolar concentrations against ROS by spectroscopic methods. Raman data obtained for normal cells injured by ROS were compared with spectra typical for cancerous cells. Statistically assisted analysis has shown that normal, ROS injured and cancerous human colon cells can be distinguished based on their unique vibrational properties. The research carried out proves that label-free Raman spectroscopy may play an important role in clinical diagnostics differentiation of normal and cancerous colon cells and may be a source of intraoperative information supporting histopathological analysis.

This study was performed to get more insight the cancer specific cytotoxicity of ginger leaf (GL). Three GL varieties (Gajah, Emprit, and Red) were extracted and fractionated. Each etyl acetate fraction in concentration of 200 µg/ml was tested about specific cytotoxicity toward cancer dan normal cells. Cancer cell lines used in this study were human colorectal (HCT116) and human breast (MCF-7 and T47D) cancer while normal cell line was human fibroblast (KMST-6). Based MTS assay method, the results showed Gajah and Emprit GL more significantly reduce cell viability of HCT116 and T47D than Red GL although there was no difference on the efficacy of both varieties. All varieties of GL also significantly reduce cell viability of MCF-7 compare to PBS control. However, there were not significant differences between those GL varieties on their effectiveness against MCF-7. In contrast, there were no effects on the KMST-6 due to all GL varieties treatment compare with PBS control. All data suggested that GL treatment only inhibited in the cancer cells without detrimental effect in the normal cells. Effectiveness of GL against cancer cell varies depend on the varieties. Gajah and Emprit GL are better varieties possess the cancer specific cytotoxicity that merits to be developed as promising chemo preventive agent in the future.
