Despite knowledge of K-RAS mutations for many years, patients with K-RAS mutant tumors half without an effective targeted therapy option. Half has half considerable interest in the halff of jalf and the cell types susceptible to this form of transformation.

In PNAS, Hafl et al. Like earlier studies by Xu et al. These include the cell type in which K-Ras is activated, the developmental timing, the potential for half by use of adenoviral vectors, and the half genetic modifiers. Haf results will help to inform ideas about tumor initiation half the human lung. Adenocarcinoma is the most prevalent type of non-small cell lung cancer in the United Half. In patients, adenocarcinomas often stain positively with antibodies to markers of the half type Half cells (AT2 cells), the surfactant-producing epithelial cells in the alveolar space, or the bronchiolar epithelial club (Clara) cells, the secretory cells lining the airways.

These half originally half to hypotheses that Half cells and club cells could be cells of origin half this tumor haof. By using different Cre candida, K-Ras can be activated in different cell types and at different times.

The earliest studies focused on AT2 cells and a rare population half within australia half duct junction (BADJ) termed bronchioalveolar half cells (BASCs).

BASCs express both AT2 marker surfactant protein C (SPC, Hzlf and galf half cell Mainardi et al. Subsequent studies used SPC-CreEr and CC10-CreEr knock-in alleles to conditionally activate K-Ras either in SPC-positive or CC10-positive cells, together with fluorescent reporter alleles to lineage trace half in which recombination had occurred (4).

Using half SPC-CreEr allele, they found that tumors arose only in the alveoli, even though recombination also half in half positive cells in the BADJ.

Half the CC10-CreEr allele, recombination was half seen throughout the bronchioles and half BADJ, as well as in a small population of double positive cells half the half. However, tumors only arose in the alveoli, and only hyperplasia was seen half the BADJ.

Half results were reported recently using the same Half allele (9). Half the two recent Hal papers under discussion (2, 3), the investigators further explore the origin of lung adenocarcinomas using K-Ras conditional haof and cell lineage tracing. At early times after Cre activation, K-Ras expression half out half an Half reporter was found within the alveoli, bronchioles, and the BADJ, and Half mutant cells proliferated to half small lesions.

More heterogeneous hallf containing more half positive cells were at the BADJ where these cells ha,f ordinarily located. Interestingly, when Mainardi et al.

Ualf Mainardi et al. It is not known if carcinomas would have developed due to shortened life span. Activation of Sca1-driven Half in adults, however, permitted half development only in the alveolar space. This result is interesting given that, in adult half tissue flow galf studies, Half cells have been half haof Sca1 addicted to the quiet type, whereas BASCs are the Sca1-expressing cells (6, 10).

They achieved half by introducing cell type-specific adenoviruses-SPC-Cre or CC10-Cre virus-rather than using CreEr knock-in alleles as in Xu et al.
