Controlling secretion to limit chemoresistance.
The tumor microenvironment influences cancer progression and therapy outcome by mechanisms not yet fully understood. In this issue of Genes & Development, Bent and colleagues (pp. 1811-1821) show how chemotherapy causes endothelial senescence. Interestingly, senescent endothelial cells do not mount a typical senescence-associated secretory phenotype but instead acutely secrete IL-6, promoting c...
متن کاملRegulation of Genes Controlling Gonadotropin Secretion
Synthesis and secretion of gonadotropic hormones is a complex process that requires precise regulation of genes encoding for the gonadompin-releasing hormone (GnRH) receptor, the common a-subunit of glycoprotein hormones and the individual P-subunits of the gonadotropins. These genes apparently can be influenced by gonadal steroids, GnRH and other peptide hormones such as activin and inhibin. G...
متن کاملPancreatic Cancer Chemoresistance to Gemcitabine
Pancreatic ductal adenocarcinoma (PDAC), commonly referred to as pancreatic cancer, ranks among the leading causes of cancer-related deaths in the Western world due to disease presentation at an advanced stage, early metastasis and generally a very limited response to chemotherapy or radiotherapy. Gemcitabine remains a cornerstone of PDAC treatment in all stages of the disease despite suboptima...
متن کاملCortactin promotes exosome secretion by controlling branched actin dynamics
Exosomes are extracellular vesicles that influence cellular behavior and enhance cancer aggressiveness by carrying bioactive molecules. The mechanisms that regulate exosome secretion are poorly understood. Here, we show that the actin cytoskeletal regulatory protein cortactin promotes exosome secretion. Knockdown or overexpression of cortactin in cancer cells leads to a respective decrease or i...
متن کاملKinesin-dependent mechanism for controlling triglyceride secretion from the liver
Despite massive fluctuations in its internal triglyceride content, the liver secretes triglyceride under tight homeostatic control. This buffering function is most visible after fasting, when liver triglyceride increases manyfold but circulating serum triglyceride barely fluctuates. How the liver controls triglyceride secretion is unknown, but is fundamentally important for lipid and energy hom...
