Here, the authors use super-resolution optical fluctuation (SOFI) for molecular density and clustering analyses, and investigate nanoscale distribution of CD4 glycoprotein.

An extracellular matrix-related prognostic and predictive indicator for early-stage non-small cell lung cancer OPEN
Su Bin LIM, Swee Jin TAN, Wan-Teck LIM & Chwee Teck LIM

Prognosis and prediction of adjuvant chemotherapy response in non-small cell lung cancer can have significant clinical impact. Here, the authors show that differential expression of a 29 extracellular matrix gene indicator, EPPI, can predict patient outcome.

Heme enables proper positioning of Drosha and DGCR8 on primary microRNAs OPEN
Alexander C. Partin, Tri D. Ngo, Emily Herrell, Byung-Cheon Jeong, Gary Hon & Yunsun Nam

Drosha and DGCR8 constitute the core Microprocessor complex, which processes primary microRNAs (pri-miRs) into mature microRNAs. Here the authors show that heme is essential for the proper processing of pri-miRs by Drosha-DGCR8, and the molecular mechanism by which heme enhances processing fidelity.
