Spurred by advances in the modeling of the airway epithelium, Pulmonary Cell News was launched in 2012 to help scientists stay at the forefront of cutting edge research. Every week, our editors hand-select the most recent, top scientific journal articles on the topics of pulmonary cells, lung cancers, and respiratory diseases such as COPD and asthma. We also highlight current job postings and upcoming events to keep the global research community connected!
The authors highlight the absence of a common definition of primary and secondary resistance and summarize their frequency and clinical characteristics.
Scientists identified four lysine residues as the sites of ubiquitination, and showed that replacement of one of them with acetylation-mimicking glutamine increased the sensitivity of mutant EGFR to erlotinib-induced degradation.
Biochemistry studies, including size exclusion chromatography, mass spectrometry, and western blot analysis, were conducted to determine the protein-protein interaction between additional sex combs-like protein 3 (ASXL3) and bromodomain-containing protein 4.
Calithera Biosciences, Inc. announced that it has dosed the first patients in its Phase Ib clinical trial of the arginase inhibitor CB-280 in adult patients with cystic fibrosis and chronic airway infection. The study will evaluate the safety and optimal dose range of CB-280 when added onto existing therapies for cystic fibrosis patients, including CFTR modulators.
Some researchers worry students will miss out on certain practical and problem-solving skills and won’t be able to judge whether the hands-on work of a scientist is a good fit for them. But instructors are developing high-tech ways to simulate the field and lab experiences.
Long-term pharmacologic 15-PGDH inhibition (PGDHi) was well-tolerated, reduced the severity of pulmonary fibrotic lesions and extracellular matrix remodeling, and improved pulmonary function in bleomycin-treated mice.

The COVID-19 pandemic has forced us to rethink what constitutes necessary travel. Many of this year’s conferences have been cancelled. Some have gone virtual. Nature presents an original analysis of the potential emissions savings of doing things differently.
To address the problem of poor reporting, Percie du Sert and a team of researchers have developed a checklist of 10 critical details each animal study needs to report, such as the number of animals used, their sex, whether they were randomly allocated to a test group and control group, and whether the researchers knew which animal was in which group.
US President Donald Trump’s government has dropped its plans to deport international students whose courses move fully online because of the coronavirus pandemic.
Applying DrugSniper to SCLC, scientists identified genes extensively explored in SCLC. The analysis suggested a remarkable vulnerability to polo-like kinase 1 inhibition in CREBBP-mutant SCLC cells.

Using lung organoids, multiple in vivo repair models, single-cell transcriptomics and lineage tracing, researchers found that alveolar type-2 epithelial cells undergoing differentiation into type-1 cells acquired pre-alveolar type-1 transitional cell state en route to terminal maturation.
