  Abstract Glioblastoma is the most frequent and the most lethal primary brain tumor among adults. Standard of care is the association of radiotherapy with concomitant or adjuvant temozolomide. However, to date, recurrence is inevitable. The CXCL12/CXCR4 pathway is upregulated in the glioblastoma tumor microenvironment regulating tumor cell proliferation, local invasion, angiogenesis, and the efficacy of radio-chemotherapy. In this study, we evaluated the effects of the novel CXCR4 antagonist, PRX177561, in preclinical models of glioblastoma. CXCR4 expression and PRX177561 effects were assessed on a panel of 12 human glioblastoma cells lines and 5 patient-derived glioblastoma stem cell cultures. Next, the effect of PRX177561 was tested in vivo, using subcutaneous injection of U87MG, U251, and T98G cells as well as orthotopic intrabrain inoculation of luciferase-transfected U87MG cells. Here we found that PRX177561 impairs the proliferation of human glioblastoma cell lines, increases apoptosis, and reduces CXCR4 expression and cell migration in response to stromal cell-derived factor 1alpha in vitro. PRX177561 reduced the expression of stem cell markers and increased that of E-cadherin and glial fibrillary acidic protein in U87MG cells consistent with a reduction in cancer stem cells. In vivo, PRX177561 reduced the weight and increased the time to progression of glioblastoma subcutaneous tumors while increasing disease-free survival and overall survival of mice bearing orthotopic tumors. Our findings suggest that targeting stromal cell-derived factor 1 alpha/CXCR4 axis by PRX177561 might represent a novel therapeutic approach against glioblastoma and support further investigation of this compound in more complex preclinical settings in order to determine its therapeutic potential.

  Title Degree of malnutrition and its relationship with major structural and eating factors in Honduran preschool population. Prevalence of breastfeeding Type Journal Article
  Year 2017 Publication Nutricion Hospitalaria Abbreviated Journal Nutr Hosp  
  Volume 34 Issue 3 Pages 639-646  
  Keywords *Honduras; *Child malnutrition; *Breastfeeding  
  Abstract Introduction: Child malnutrition remains a serious public health problem in Honduras, with a national prevalence according to the World Health Organization (WHO) reference values of 29% in children under fi ve. In addition, the average chronic malnutrition in the region amounts to 80% in poor and indigenous communities, making Honduras the second country in Central America with the highest incidence of chronic malnutrition. Another problem of the region is the early cessation of exclusive breastfeeding: only 29.7% of children were exclusively breastfed until they were six months. Therefore, the study seeks to understand, identify and quantify the situation determinants and provide information for the design of public policies. Material and method:: The study consisted of a cross-sectional descriptive anthropometric assessment in which the nutritional status and the prevalence of undernourishment, malnutrition and malnutrition in 141 children aged between six months and fi ve years, belonging to urban and rural regions of the country, were analyzed, as well as assessing the prevalence of breastfeeding in fi ve Honduran departments (Intibuca, Lempira, Atlantida, Olancho and Francisco Morazan). Results and conclusion: When making the analysis by departments, differences regarding nutritional status and breastfeeding were observed between urban and rural areas, the latter being doubled in the case of chronic malnutrition and underweight, with percentages of 14.6% in urban areas versus28.8% in rural areas, and 4.6% in urban areas compared to 9% in rural areas, respectively. However, with respect to acute malnutrition and overweight in both regions, similar values were observed, above 1.1% for acute and 14% for overweight malnutrition. In relation to exclusive breastfeeding for six months, the departments of Olancho and Lempira maintained it for two years, with a percentage distribution of 80% and 48%, respectively. It must be noted that 36% of mothers did not provide breastfeeding, with the highest rate (15%) in the department of Francisco Morazan.
