A frequent somatic mutation in CD274 3′‐UTR leads to protein over‐expression in gastric cancer by disrupting miR‐570 binding

Human Mutation, 2012
Inhibitory costimulatory molecule CD274 expresses in various cancers and contributes to cancer immune evasion by inhibiting T cell activation and proliferation, yet the regulatory mechanisms for CD274 overexpression in cancers are poorly understood.

Vivid Structural Coloration in Transparent MXene‐Cellulose Nanocrystals Composite Films

Advanced Functional Materials, EarlyView.
Vivid structural coloration in reflectance and high transparency in transmittance modes are observed in biopolymer‐layered composite films. The ultrathin multilayered structures have unique optical appearance, near‐infrared bandgap, and strong optical reflection caused by alternating MXene and cellulose nanocrystals layers with high refractive index ...
