The activity of betulin-3,28-diphosphate (BDP) in combination with the cytostatics such as 5-fluorouracil (5-FU) and hydrazine sulfate (HS) was demonstrated by using the transplanted Ehrlich ascites carcinoma (EAC) in mice. The dose-dependent effect of combination drugs BDP + HS and BDP + 5-FU was revealed by in vitro experiments on rats. The synergetic effect of HS and BDP on oxidative stress and energy metabolism was established. The malonic dialdehyde (MDA) level both in plasma and erythrocytes decreased by 87 ± 2%, and the superoxide dismutase (SOD) activity increased by 105 ± 7% in comparison with the control...

Mutations and reductions in mitochondrial DNA (mtDNA), which are frequent in human tumors, may contribute to enhancing their malignant phenotypes. However, the effects of mtDNA abnormalities in colorectal cancer remain largely unknown. In this study, mtDNA-reduced cell model was established by partial depletion of mtDNA in SW480 cells and the effects of mtDNA reduction in colorectal cancer cells were investigated. We found that mtDNA-reduced cells had enhanced glucose uptake and generated markedly higher level of lactate...

The main aim of this study was to establish a novel paclitaxel (PTX)-resistant human gastric carcinoma cell line and to investigate its biological significance. A cell line, MGC803/PTX, was established by gradually increasing PTX density on the basis of MGC803 over a period of 10 months. In addition, a pair of resistant cell lines (SW620 and SW620/PTX) were added to further explain the resistant mechanism of PTX. The drug resistance index and stability of MGC803/PTX cells were detected using the Cell Counting Kit-8 method...

Background: Colorectal cancer is the third most common and the fourth most lethal cancer in the world. In the majority of cases, patients are diagnosed at an advanced stage or even metastatic, thus explaining the high mortality. The standard treatment for patients with locally advanced non-metastatic rectal cancer is neoadjuvant radio-chemotherapy (NRCT) with 5-fluorouracil (5-FU) followed by surgery, but the resistance rate to this treatment remains high with approximately 30% of non-responders...

Malignant transformation of mediastinal mature teratoma is extremely rare and worsens the prognosis of the disease. Transformation can appear synchronously to or several years after the initial diagnosis. Clinical and radiological signs can orientate the clinician but the definitive diagnosis is obtained thanks to histology. An 11 year-old boy presented with a mediastinal mature teratoma and bone and pulmonary metastases. He received six cycles of chemotherapy combining etoposide, ifosfamide, cisplatin, followed by resection of a 16×14×9cm mediastinal mass...
