Tumor heterogeneity dictates sensitivity to gefitinib (Iressa(TM)/ZD1839) in solid tumor models

The epidermal growth factor receptor (EGFR) and its ligands are overexpressed in many human tumors, including bladder and pancreas, correlating with a more aggressive tumor phenotype and poor patient prognosis. We initiated the present study to characterize the heterogeneity of gefitinib responsiveness in a panel of human bladder and pancreatic cancer cell lines in order to identify the biological characteristics of EGFR-dependent proliferation that could be used to prospectively identify drug-sensitive tumors. A second objective was to elucidate how to best exploit these results by utilizing gefitinib in combination therapy. To these ends, we examined the effects of the EGFR antagonist gefitinib on proliferation and apoptosis in a panel of 18 human bladder cancer cell lines and 9 human pancreatic cancer cell lines. Our data confirmed the existence of marked heterogeneity in Iressa responsiveness with less than half of the cell lines displaying significant growth inhibition by clinically relevant concentrations of the drug. Gefitinib responsiveness was found to be p27 kip1 dependent as DNA synthesis was restored following exposure to p27siRNA. Unfortunately, Iressa responsiveness was not closely linked to surface EGFR or TGF-α expression in the bladder cancer cells, however, cellular TGF-α expression correlated directly with Iressa sensitivity in the pancreatic cancer cell lines. These findings provide the potential for prospectively identifying patients with drug-sensitive tumors. ^ Further studies aimed at exploiting gefitinib-mediated cell cycle effects led us to investigate if gefitinib-mediated TRAIL sensitization correlated with increased p27kip1 accumulation. We observed that increased TRAIL sensitivity following gefitinib exposure was not dependent on p27 kip1 expression. Additional studies initiated to examine the role(s) of Akt and Erk signaling demonstrated that exposure to PI3K or MEK inhibitors significantly enhanced TRAIL-induced apoptosis at concentrations that block target phosphorylation. Furthermore, combinations of TRAIL and the PI3K or MEK inhibitors increased procaspase-8 processing above levels observed with TRAIL alone, indicating that the effects were exerted at the level of caspase-8 activation, considered the earliest step in the TRAIL pathway. ^

Geochemistry and oxygen and iron isotope ratios of mafic rocks

Recycling of oceanic crust into the deep mantle via subduction is a widely accepted mechanism for creating compositional heterogeneity in the upper mantle and for explaining the distinct geochemistry of mantle plumes. The oxygen isotope ratios (d18O) of some ocean island basalts (OIB) span values both above and below that of unmetasomatised upper mantle (5.5 ± 0.4 per mil) and provide support for this hypothesis, as it is widely assumed that most variations in d18O are produced by near-surface low-temperature processes. Here we show a significant linear relationship between d18O and stable iron isotope ratios (d57Fe) in a suite of pristine eclogite xenoliths. The d18O values of both bulk samples and garnets range from values within error of normal mantle to significantly lighter values. The observed range and correlation between d18O and d57Fe is unlikely to be inherited from oceanic crust, as d57Fe values determined for samples of hydrothermally altered oceanic crust do not differ significantly from the mantle value and show no correlation with d18O. It is proposed that the correlated d57Fe and d18O variations in this particular eclogite suite are predominantly related to isotopic fractionation by disequilibrium partial melting although modification by melt percolation processes cannot be ruled out. Fractionation of Fe and O isotopes by removal of partial melt enriched in isotopically heavy Fe and O is supported by negative correlations between bulk sample d57Fe and Cr content and bulk sample and garnet d18O and Sc contents, as Cr and Sc are elements that become enriched in garnet- and pyroxene-bearing melt residues. Melt extraction could take place either during subduction, where the eclogites represent the residues of melted oceanic lithosphere, or could take place during long-term residence within the lithospheric mantle, in which case the protoliths of the eclogites could be of either crustal or mantle origin. This modification of both d57Fe and d18O by melting processes and specifically the production of low-d18O signatures in mafic rocks implies that some of the isotopically light d18O values observed in OIB and eclogite xenoliths may not necessarily reflect near-surface processes or components.

(Table 1) Composition of paraffin hydrocarbons at DSDP Site 56-434

Geochemical investigation of 18 samples of sediments from Site 434 involved determining the content of organic carbon, of bitumoid A (The chloroform A-chl and alcohol-benzene A-alb extracts) and its various fractions, and of individual hydrocarbons as well as the structural group composition of resins. We identified certain samples that differed sharply from the rest by their increased bitumen content and relatively low molecular hydrocarbons and by the fact that their resinous components were more neutral and aliphatic in composition. The distribution of bitumoid and its components seems to reflect migration processes in operation during the early stages of the transformation of organic matter.

Calibración del modelo de Hargreaves para la estimación de la evapotranspiración de referencia en Coronel Dorrego, Argentina

La Organización de las Naciones Unidas para la Agricultura y la Alimentación FAO propone el uso de la ecuación de Penman-Monteith (PM) como el estándar para la estimación de la evapotranspiración de referencia y para la calibración de otras ecuaciones. El principal inconveniente del uso de esta ecuación es que requiere datos que no se tienen en la mayoría de las estaciones. El uso de métodos de cálculos alternativos es usual en la bibliografía. El método de Hargreaves (HG), recomendado por la FAO, es el más usado en la bibliografía cuando sólo se dispone de los datos de temperaturas. El principal objetivo de este trabajo es analizar la posibilidad de calibración y ajuste del método HG en la estación de Coronel Dorrego. Se han comparado los métodos PM y HG, encontrándose una buena correlación entre ambos. Se concluye que el modelo HG es una metodología adecuada, para la zona de Coronel Dorrego y se sugiere la fórmula siguiente: ETo HG = 0,00206⋅Ra⋅(Tmáx-- T mín) 0,49⋅(tm+17,8) mm/día
