Progenitor cell engraftment in the lung: at last?
Engraftment of progenitor cells to effect repair of injured lungs has been a major challenge. A new study combines a conditioning strategy adopted from bone marrow transplantation with a lung injury model to bring this potential therapeutic approach closer to reality.

Liquid biopsies reveal the dynamic nature of resistance mechanisms in solid tumors
Two new studies demonstrate that so-called 'liquid biopsies' may reveal important genomic information needed to monitor treatment responses, forecast tumor recurrences, and provide a rationale for novel therapeutic strategies in patients with lung cancer and colon cancer.

Tumorigenicity and genetic profiling of circulating tumor cells in small-cell lung cancer
Circulating tumor cells from patients with small-cell lung cancer can form tumors in mice, and their derived explants recapitulate the patients' response to chemotherapy.

An ultrasensitive method for quantitating circulating tumor DNA with broad patient coverage
Aaron Newman and his colleagues introduce a next-generation sequencing–based approach for the cost-effective detection and quantitation of tumor-derived circulating DNA in both early- and advanced-stage tumors and with high levels of sensitivity and specificity. CAPP-Seq (cancer personalized profiling by deep sequencing) can simultaneously detect multiple mutations and mutation types, including rearrangements. Here, utility is demonstrated for non–small-cell lung cancer.

The quest to overcome resistance to EGFR-targeted therapies in cancer
Despite the initial promise of cancer therapies targeted against the epidermal growth factor receptor (EGFR), tumors treated with these agents eventually develop resistance. In this Review, the authors outline the complex mechanisms by which tumors become resistant to EGFR-targeted drugs and antibodies and offer insights into new strategies that might be employed to circumvent therapeutic resistance.

Oncogenic and drug-sensitive NTRK1 rearrangements in lung cancer
The authors employ targeted next-generation sequencing to identify driving oncogenic alterations in patients with lung cancer with no known oncogenes. They discover two gene fusions involving NTRK1 that lead to constitutive activation of the kinase TRKA and can drive transformation. The fusions can be targeted with available kinase inhibitors and may represent therapeutic targets.

Chipping away at the lung cancer genome
Kinase inhibitors are now standard treatment for patients with lung cancer whose tumors harbor specific mutant kinases. Four recent studies, including three in this issue (pages 375–384), have identified new fusion proteins involving another receptor tyrosine kinase that may potentially be responsive to existing targeted therapies.

Identification of new ALK and RET gene fusions from colorectal and lung cancer biopsies
Using high-coverage targeted next-generation sequencing, this report provides a catalog of genetic alterations in colorectal and lung cancers, identifying previously unknown alterations, such as JAK2 mutations and KIF5B-RET fusions, that may represent druggable targets.

KIF5B-RET fusions in lung adenocarcinoma
The authors report a new type of genetic alteration in lung adenocarcinoma. Fusions of KIF5B with RET kinase are found in 1–2% of lung cancer patients, segregate from other known alterations and can potentially be targeted using RET kinase inhibitors.

RETRACTED ARTICLE: EGFR and MET receptor tyrosine kinase–altered microRNA expression induces tumorigenesis and gefitinib resistance in lung cancers
The authors identify a set of microRNAs regulated by EGFR and MET that are involved in the oncogenic signaling exerted by these receptors and also modulate the response of tumors to targeted EGFR inhibition. These results shed light on the known contribution of MET to therapy resistance and suggest that MET-regulated microRNAs can be key mediators of its effects and potential markers of clinical utility.

A crucial requirement for Hedgehog signaling in small cell lung cancer
The authors find that cell-intrinsic activation of Hedgehog signaling without genetic alterations is a contributing feature to the progression and chemotherapy resistance of small-cell lung carcinoma, and that Hedgehog inhibition can prevent lung cancer growth and recurrence.

Compromised CDK1 activity sensitizes BRCA-proficient cancers to PARP inhibition
This report identifies Cdk1's phosphorylation of BRCA1 as an important regulator of BRCA1's DNA repair function. Cdk1 inhibition renders cancer cells sensitive to PARP inhibition, and the combination treatment can inhibit tumor growth in vivo, expanding the potential application of PARP inhibitors beyond BRCA1-deficient tumors.

Inflammatory proteinase slips into tumor cells
Inflammatory cells can promote tumor cell proliferation, but the range of mechanisms has not been fully explored. A proteinase produced by neutrophils is now shown to enter tumor cells and promote their proliferation (pages 219–223).

Neutrophil elastase–mediated degradation of IRS-1 accelerates lung tumor growth
Neutrophil elastase speeds up the progression of lung cancer by degrading insulin receptor substrate-1 and thereby phosphatidylinositol 3-kinase. This is the first description of a secreted proteinase gaining access to the inside of a cell to alter intracellular signaling (pages 161–163).
