Hide Abstract
Gastric cancer is the fourth most frequent type of cancer and the second most frequent cause of cancer mortality worldwide. Only a modest number of gastric carcinoma cell lines have been isolated thus far. Here we describe the establishment and cytogenetic characterization of three new gastric cancer cell lines obtained from primary gastric adenocarcinoma (ACP02 and ACP03) and cancerous ascitic fluid (AGP01) of individuals from northern Brazil. ACP02, ACP03, and AGP01 cell lines are presently in the 60th passage. The cell lines grew in a disorganized single layer with some agglomerations and heterogeneous divisions (bipolar and multipolar). All cell lines exhibited a composite karyotype with several clonal chromosome alterations. Trisomy 8 was the most frequent alteration. Chromosome 8 aneusomy was confirmed by fluorescence in situ hybridization. All cell lines also exhibited trisomy 7 and deletion of chromosome arm 17p. These results suggest that, although frequent chromosome alterations are commonly observed due to culture process, the ACP02, ACP03, and AGP01 cell lines and primary gastric cancer from individuals of northern Brazil share genetic alterations, supporting use of these cell lines as a model of gastric carcinogenesis in this population.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
