Journal Club: Tumors create an acidic environment that helps them invade surrounding tissues

Posted on March 29, 2019 by Jessica P. Johnson

Cancer cells tend to turn their extracellular environment acidic, thus helping these rogue cells thrive while creating a hostile environment for normal ones. Acidosis promotes tumor growth, metastasis and drug resistance, while helping tumor cells evade the immune system. But … Continue reading →

Journal Club: Cellular context determines whether factor promotes or tamps down cancer

Posted on November 14, 2017 by Charlotte Schubert

Some cellular factors have an impressive multitude of roles. One prime example is LKB1 (Liver Kinase B1). It controls both cell metabolism and cell polarity, telling cells which end is which. It also appears to act as both a tumor … Continue reading →

Journal Club: A new take on why tumors develop drug resistance

Posted on June 26, 2015 by Charles Choi

Cancer’s notorious resistance to therapy is often explained as the result of natural selection of newly mutating cells. Cancer-killing drugs wipe out nearly all of a tumor’s cells, but random mutations may allow for drug resistance in some cells, and … Continue reading →
