It is estimated that about 25% of cancers appear due to chronic infection or other types of chronic inflammation. However, almost all cancers have abnormal or/and constitutive inflammatory signaling activation. Much progress has been made in elucidating the mechanisms by which inflammatory signaling drives tumor progression and metastasis. However, how the abnormal and constitutive inflammatory...
Vascular endothelial growth factor (VEGF) is a key angiogenic molecule that plays an important role in the growth and metastasis of many types of human cancer, including pancreatic adenocarcinoma. In this study, we explored the regulation of VEGF in human pancreatic cancer cells. Over 70% of the human pancreatic cancer cell lines studied in vitro secreted constitutively high levels of VEGF. Hig...
Although it has been suggested that induced and constitutive plant resistance should have different effects on insect herbivore population dynamics, there is little experimental evidence that plant resistance can influence herbivore populations longer than one season. We used a density-manipulation experiment and model fitting to examine the effects of constitutive and induced resistance on her...
