Oncogenic KRAS mutations found in 20% to 30% of all non-small cell lung cancers (NSCLC) are associated with chemoresistance and poor prognosis. Here we demonstrate that activation of the cell protective stress response gene NRF2 by KRAS is responsible for its ability to promote drug resistance. RNAi-mediated silencing of NRF2 was sufficient to reverse(More)
The photothermal effect of plasmonic nanostructures has numerous applications, such as cancer therapy, photonic gene circuit, large cargo delivery, and nanostructure-enhanced laser tweezers. The photothermal operation can also induce unwanted physical and biochemical effects, which potentially alter the cell behaviors. However, there is a lack of techniques(More)
At the onset of collective cell migration, a subset of cells within an initially homogenous population acquires a distinct 'leader' phenotype with characteristic morphology and motility. However, the factors driving the leader cell formation as well as the mechanisms regulating leader cell density during the migration process remain to be determined. Here(More)
Cells process various mechanical cues in the microenvironment to self-organize into high-order architectures during tissue morphogenesis. Impairment of morphogenic processes is the underlying cause of many diseases; as such, understanding the regulatory mechanisms associated with these processes will form the foundation for the development of innovative(More)
A gold nanorod-locked nucleic acid nano-biosensor for dynamic single-cell gene expression analysis in living cells and tissues is developed. The nanoparticle facilitates endocytic delivery and dynamic monitoring of the gene expression in human umbilical cord endothelial cells, mouse skin tissues, mouse retina tissues, and mouse cornea tissues at the(More)
Angiogenesis is a complex cellular process involving highly orchestrated invasion and organization of endothelial cells (ECs) in a three-dimensional (3D) environment. Recent evidence indicates that Notch signaling is critically involved in regulating specialized functions and distinct fates of ECs in newly formed vasculatures during angiogenesis. Here, we(More)
On page 6034, P. K. Wong and co-workers demonstrate a nanorod-based biosensor for dynamic single-cell analysis in native tissue microenvironments. The biosensor is capable of monitoring spatiotemporal mRNA expression in primary human cells, capillary networks, and animal tissues, including the skin, retina, and cornea, challenged mechanically and(More)
Acrylamide (ACR) is a vinyl monomer with established human neurotoxic effects, which is characterized by the accumulation of neurofilaments (NFs) in the distal swellings of large axons in peripheral and central nervous systems. However, the mechanisms of neurotoxicity remain unclear. The objective is to investigate the neuroprotective effect of calpeptin(More)
