Although combined chemotherapy regimen leads to 80% remission in children with acute lymphocytic leukemia (ALL), malnutrition and altered serum trace elements as a consequence of chemotherapy agents, have become the new issue to deal with. With the aim to evaluate each trace element in childhood ALL, we investiguâtes six main trace elements before and after induction chemotherapy while considering age, gender and chemotherapy protocol as confounding factors. Thirty-six newly diagnosed ALL children were recruited, and trace elements were assessed by atomic absorption spectrometry technique. Trace elements (Zinc, Copper, Manganese, Magnesium, Chromium and Iron) decreased significantly after induction chemotherapy. Considering the confounding factors, mean difference of elements decreased significantly, except for Chromium. Its mean difference was only significant in children younger than 10 and those who had received standard risk chemotherapy. In conclusion, all the studied trace elements decreased significantly after induction chemotherapy session in ALL children. This highlights the importance of complementary and supplementary management. Gunagratinib order A larger cohort study with longer follow up is warranted to elucidate the long-term effect of chemotherapy on these trace elements on the general health status, quality of life or risk of relapse in ALL children.In conclusion, all the studied trace elements decreased significantly after induction chemotherapy session in ALL children.

Statins, 3-hydroxy-3-methylglutaryl co-enzyme A (HMG-CoA) reductase inhibitors, have been shown to be effective in the treatment of cardiovascular disease. Recent reports demonstrate an anticancer effect induced by statins on lung and prostate cancer cells. The present study aimed to investigate the therapeutic potential of Simvastatin can serve as chemotherapeutic agent against human breast cancer MCF-7 and MDA-MB-231 cell lines. The cytotoxic effect of simvastatin against breast cancer cells were evaluated using MTT assay. The related mechanism of cell death was further determined by trypan blue staining, morphological changes observation, and drug combination index. The results showed that simvastatin treatment substantially induced cell death in a dose-dependent and time-dependent manner on MCF-7 and MDA-MB-231 cells. Simvastatin exhibited a highly cytotoxic effect on MCF7 and MDA-MB-231 with half-maximal (50%) inhibitory concentration (IC50) 8.9 μM and 4.5 μM respectively. Consistently, we observed antiproliferative effect of Simvastatin was associated with apoptosis on breast cancer cell lines by determination of morphological changes. Moreover, this drug demonstrated a synergistic activity with doxorubicin on triggering cell death in MCF7 cells, but not in MDA-MB-231. Simvastatin has a potent cytotoxic effect resulting in the death of human breast cancer MCF-7 and MDA-MB-231 cell lines, demonstrating its potential as a new candidate for cancer drug.
.. This study aimed to investigate the cytotoxicity, anti-proliferation and anti-migration effect of the ethanol extract of Aaptos suberitoides on trastuzumab-resistant HER2+ breast cancer cell line. Aaptos suberitoides was collected from Tinjil Island, Banten, Indonesia, and was processed with maceration and ethanol extraction. HCC-1954 cells were treated with the ethanol extract and then followed by 3- [4, 5-dimethylthiazol-2-yl] -2.5 diphenyl tetrazolium bromide (MTT) assay to assess cytotoxicity, clonogenic assay and three-dimensional (3D) spheroid assay to evaluate anti-proliferative effect in two-dimensional and 3D model, respectively, and wound healing assay to determine anti-cell migration effect. Four parametric regression was used to analyse the IC50. This study revealed that the ethanol extract of Aaptos suberitoides suppressed cell viability in correlation with cell death induction. The IC50 values of the ethanol extract of Aaptos suberitoides using MTT assay and clonogenic assay were 12.0 ppm and 4.36 ppm, respectively. The extract demonstrated an inhibition effect on spheroid growth. In low concentration, the extract of Aaptos suberitoides inhibited cell migration. Furthermore, MS analysis showed that the most abundant compounds in this extract has molecular weight m/z 229.81 [M+H]+. This study revealed that the ethanol extract of Aaptos suberitoides demonstrates cytotoxicity, anti-proliferation and anti-migration effect as well as inhibition effect on three-dimensional spheroid growth in trastuzumab-resistant HER2+ breast cancer cell line.
.. Liver cancer is one of the most common causes of cancer death, with reduced survival rates. The development of new chemotherapeutic agents is essential to find effective cytotoxic drugs that give minimum side effects to the surrounding healthy tissues. The main objective of the present study was to evaluate the cytotoxic effects and mechanism of cell death induced by the crude and diethyl ether extract of Xylocarpus mouccensis on the human hepatocellular carcinoma cell line. The cytotoxicity activity was measured using the MTS assay. The mode of cell death determined by the apoptosis study, DNA fragmentation analysis done by using the TUNEL system. The pathway study or mechanism of apoptosis observed by study caspases 8, 9, 3/7 Glo-caspases method. In this study, the methanol extracts prepared from leaf Xylocarpus mouccensis leaf produced cytotoxicity effect with IC50 (72hr) < 30µg/ml. The IC50 value at 72 hours exerted by diethyl ether extract of Xylocarpus moluccensis leaf was 0.22 µg/ml, which was more cytotoxic than to that of crude methanol extract. The results obtained by the colorimetric TUNEL system suggest that methanol crude extract of Xylocarpus moluccensis (leaf), diethyl ether extract of Xylocarpus moluccensis (leaf) and methanol extract of Xylocarpus granatum (bark) induced DNA fragmentation in the HepG2 cell line. Besides, the caspase-Glo assay demonstrated that diethyl ether leaf extract of Xylocarpus moluccensis triggered apoptotic cell death via activation of caspases -8, and -3/7 However, no visible activation was noticed for caspase -9. Furthermore, TLC indicates the presence of potential metabolites in an extract of Xylocarpus moluccensis. Thus, the present study suggests the remarkable potential of active metabolites in the extract of Xylocarpus moluccensis as a future therapeutic agent for the treatment of cancer.
