Role of hypoxia in pemetrexed-resistance of mesothelioma mediated by proton-coupled folate transporter, and preclinical activity of new anti-LDH compounds
Introduction There are few effective therapies for malignant pleural mesothelioma (MPM), which remains one of the most lethal cancers. We previously demonstrated that low expression of the PCFT transporter, both at mRNA and protein levels, is associated with shorter survival of MPM patients treated with pemetrexed (Giovannetti et al., 2017). Since hypoxia has also been associated to antifolate-resistance (Raz et al, 2014), this study was aimed at elucidating key factors in pemetrexed resistance and hypoxia that may contribute to the rational development of novel therapeutic interventions against mesothelioma. Methods The levels of PCFT and of the hypoxia marker carbonic anhydrase-IX were de…
Factors controlling plankton community production, export flux, and particulate matter stoichiometry in the coastal upwelling system off Peru
Eastern boundary upwelling systems (EBUS) are among the most productive marine ecosystems on Earth. The production of organic material is fueled by upwelling of nutrient-rich deep waters and high incident light at the sea surface. However, biotic and abiotic factors can modify surface production and related biogeochemical processes. Determining these factors is important because EBUS are considered hotspots of climate change, and reliable predictions of their future functioning requires understanding of the mechanisms driving the biogeochemical cycles therein. In this field experiment, we used in situ mesocosms as tools to improve our mechanistic understanding of processes controlling organ…
