PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Ectopic or Drastic Increase of CSCs after Chemotherapy

Go Yoshida   (2014-11-06 09:59)  Tokyo Medical and Dental University email

As shown in Figure-4 of this case report, conventional chemotherapy is considered to be partially responsible for the increase of cancer stem cells (CSCs) in number in vivo. The recent Nature article entitled as “Oncogene ablation-resistant pancreatic cancer cells depend on mitochondrial function” investigated into the drastic proliferation of mutant KRAS-driven pancreatic ductal adenocarcinoma CSCs utilizing the Tet-ON/OFF and ON system. Notably, they have also revealed the metabolic features of CSCs to depend more on mitochondria as compared with non-CSCs or before oncogene ablation.
