Results We observed mutations in KRAS in 59.4% KPT-8602 of patients. Bevacizumab was used in combination with oxaliplatin based regimens. There was no significant
difference for progression free survival (PFS) and overall survival (OS) in patients with oxaliplatin based cytotoxic chemotherapy plus bevacizumab according to the status of KRAS mutation. After first-line therapy, 28 patients (87.5%) received second-line therapy. In univariate analysis, KRAS mutations did not have a major prognostic value for PFS (hazard ratio, 1.007; 95% confidence interval [CI], 0.469 to 2.162; p > 0.05) or OS (hazard ratio, 0.548; 95% Cl, 0.226 to 1.328; p > 0.05). In addition, anti-EGFR therapies did not affect the impact on OS.
Conclusion KRAS mutation is neither a predictive for bevacizumab nor a prognostic for OS in CRC patients receiving anti-VEGF therapy.”
“The antioxidant, nitric oxide (NO) scavenging and malondialdehyde (MDA) scavenging activities of different Zataria multiflora (ZM) chemotype essential oils (EOs) were investigated.
The main components are: signaling pathway ZM1 (carvacrol, p-cymene), ZM2 (carvacrol, p-cymene), ZM3 (carvacrol, p-cymene), ZM4 (linalool), ZM5 (carvacrol, p-cymene, thymol), ZM6 (thymol, carvacrol, p-cymene, gamma-terpienene), ZM7 (thymol, p-cymene, gamma-terpienene) and ZM8 (carvacrol, linalool, p-cymene, thymol). The antioxidant capacities were estimated to be 863 +/- 55, 619 +/- 27, 876 +/- 32, 38 +/- 9, 649 +/- 50, 595 +/- 40, 696 +/- 41 and 618 +/- 9 mu g ascorbic acid equivalents per millilitre for ZM1 to ZM8, respectively. The NO scavenging values were estimated to be 54 +/- 1.2, 50 +/- 1.4, 63 +/- 1, 0.60 +/- 0.1, 53 +/- 0.7, 53 +/- 1.5, 38 GW2580 order +/- 1.1 and 46.5 +/- 3 mu g ascorbic acid equivalents per millilitre for ZM1 to ZM8, respectively. The MDA scavenging values were
estimated to be 19 +/- 1, 9 +/- 1, 24 +/- 1, 1.6 +/- 0.6, 12 +/- 1, 11.7 +/- 1, 10 +/- 1 and 12.5 +/- 1.3 mu g ascorbic acid equivalents per millilitre for ZM1 to ZM8, respectively. Among these EOs, ZM3 with carvacrol and p-cymene had higher antioxidant, NO scavenging and MDA scavenging properties.”
“Purpose The novel heat shock protein tumor necrosis factor receptor-associated protein 1 (TRAP1) is associated with multidrug resistance in colorectal cancer (CRC) cells in vitro. Excision repair cross-complementation group 1 (ERCC1) expression levels in tumor tissues also predict clinical outcomes in metastatic CRC patients receiving combination oxaliplatin and 5-fluorouracil treatment. We investigated whether TRAP1 and ERCC1 protein expression by immunohistochemistry predict clinical outcomes in CRC patients.
Materials and Methods The study population consisted of 56 patients with metastatic CRC who received first-line oxaliplatin/5-fluorouracil therapy. Clinical response and overall survival (OS) by levels of the markers TRAP1 and ERCC1 were evaluated.
Results The rates of TRAP1 and ERCC1 expression were 21% and 52%, respectively.
