1956

Context: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers worldwide. Despite significant progresses in the last decades, the origin of this cancer remains unclear and no efficient therapy exists. PDAC does not arise de novo: three remarkable different types of pancreatic lesions can evolve towards pancreatic cancer. These precursor lesions include: Pancreatic intraepithelial neoplasia (PanIN) that are microscopic lesions of the pancreas, Intraductal Papillary Mucinous Neoplasms (IPMN) and Mucinous Cystic Neoplasms (MCN) that are both macroscopic lesions. However, the cellular origin of these lesions is still a matter of debate. Classically, neoplasm initiation or progression is driven by several genetic and epigenetic alterations. The aim of this review is to assemble the current information on genetic mutations and epigenetic disorders that affect genes during pancreatic carcinogenesis. We will further discuss the interest of the genetic and epigenetic alterations for the diagnosis and prognosis of PDAC. Large genetic alterations (chromosomal deletion/amplification) and single point mutations are well described for carcinogenesis inducers. Mutations classically occur within key regions of the genome. Consequences are various and include activation of mitogenic pathways or silencing of apoptotic processes. Alterations of K-RAS, P16 and DPC4 genes are frequently observed in PDAC samples and have been described to arise gradually during carcinogenesis. DNA methylation is an epigenetic process involved in imprinting and X chromosome inactivation. Alteration of DNA methylation patterns leads to deregulation of gene expression, in the absence of mutation. Both genetic and epigenetic events influence genes and non-coding RNA expression, with dramatic effects on proliferation, survival and invasion. Besides improvement in our fundamental understanding of PDAC development, highlighting the molecular alterations that occur in pancreatic carcinogenesis could provide new clinical tools for early diagnosis of PDAC and the molecular basis for the development of new effective therapies. 
 Question: Which is the molecular mechanism underlying K-ras alterations in carcinomas?
point mutations

Context: If a business wants to sell its products internationally, it had better do some market research first. This is a lesson that some large American corporations have learned the hard way. What's in the name? Sometimes the problem is the name. When General Motors introduced its Chevy Nova into Latin America, it overlooked the fact that Nova in Spanish means "It doesn't go". Sure enough, the Chevy Nova never went anywhere in Latin America. Translation problems Sometimes it is the slogan that doesn't work. No company knows this better than Pepsi-Cola, with its "Come alive with Pepsi!" campaign. The campaign was so successful in the United States , Pepsi translated its slogan literally for its international campaign. As it turned out , the translations weren't quite right. Pepsi was begging Germans to "Come out of the grave " and telling the Chinese that "Pepsi brings your ancestors back from the grave." A picture's worth a thousand words Other times, the problem involves packaging . A picture of a smiling baby has helped sell countless jars of Gerber baby food. When Gerber started selling baby food in Africa, they used the same packaging as in the US, with the smiling baby on the label. Later they learned that in African countries, the picture on the jar shows what the jar has in it, for many people there can't read. Twist of fate Even the culture and religious factors and pure coincidence can be involved. Thorn McAn shoes have a Thorn McAn "signature" inside. To people in Bangladesh, which is a Muslim country, this signature looked like Arabic script for the word Allah. In that country, feet are considered unclean, and Muslims felt the company was offending God's name by having people walk on it. 
 Question: What was "Gerber's problem"?
