Methods: We performed genomic, transcriptional and proteomic analyses of human colon cancer cells with sequentially increasing levels of MTX-resistance.

Results: The genomic amplification evolved in three phases (pre-amplification, homogenously staining region (HSR) and extrachromosomal DNA (ecDNA)).

A new threshold selection method for species distribution models with presence-only data: Extracting the mutation point of the P/E curve by threshold regression.

Selecting thresholds to convert continuous predictions of species distribution models proves critical for many real-world applications and model assessments. Prevalent threshold selection methods for presence-only data require unproven pseudo-absence data or subjective researchers' decisions. This study proposes a new method, Boyce-Threshold Quantile Regression (BTQR), to determine thresholds objectively without pseudo-absence data.

A High-Rate, Durable Cathode for Sodium-Ion Batteries: Sb-Doped O3-Type Ni/Mn-Based Layered Oxides.

O3-Type layered oxides are widely studied as cathodes for sodium-ion batteries (SIBs) due to their high theoretical capacities. However, their rate capability and durability are limited by tortuous Na diffusion channels and complicated phase evolution during Na extraction/insertion. Here we report our findings in unravelling the mechanism for dramatically enhancing the stability and rate capability of O3-NaNiMnSbO (NaNMS) by substitutional Sb doping, which can alter the coordination environment and chemical bonds of the transition metal (TM) ions in the structure, resulting in a more stable structure with wider Na transport channels.

Noninvasive monitoring of hepatic glutathione depletion through fluorescence imaging and blood testing.

Hepatic glutathione plays a key role in regulating redox potential of the entire body, and its depletion is known to increase susceptibility to oxidative stress involved in many diseases. However, this crucial pathophysiological event can only be detected noninvasively with high-end instrumentation or invasively with surgical biopsy, limiting both preclinical research and clinical prevention of oxidative stress-related diseases. Here, we report that both in vivo fluorescence imaging and blood testing (the first-line detection in the clinics) can be used for noninvasive and consecutive monitoring of hepatic glutathione depletion at high specificity and accuracy with assistance of a body-clearable nanoprobe, of which emission and surface chemistries are selectively activated and transformed by hepatic glutathione in the liver sinusoids.

Hyperfluorescence Imaging of Kidney Cancer Enabled by Renal Secretion Pathway Dependent Efflux Transport.

Renal tubular secretion is an active efflux pathway for the kidneys to remove molecules but has yet to be used to enhance kidney cancer targeting. We report indocyanine green (ICG) conjugated with a 2100 Da PEG molecule (ICG-PEG45) as a renal-tubule-secreted near-infrared-emitting fluorophore for hyperfluorescence imaging of kidney cancers, which cannot be achieved with hepatobiliary- and glomerular-clearable ICG. This pathway-dependent targeting of kidney cancer arises from the fact that the secretion pathway enables ICG-PEG45 to be effectively effluxed out of normal proximal tubules through P-glycoprotein transporter while being retained in cancerous kidney tissues with low P-glycoprotein expression.

Tailoring Kidney Transport of Organic Dyes with Low-Molecular-Weight PEGylation.

Subtle changes in size can induce distinct responses of the body to hard nanomaterials; however, it is largely unknown whether just a few ethylene oxide unit differences in soft poly(ethylene glycol) (PEG) molecules could significantly alter the renal clearance of small molecules. By systematically investigating in vivo transport of the representative renal clearable organic dyes, IRDye800CW after being conjugated with a series of PEG molecules with molecular weight (MW) below 10 kDa, we found a MW-dependent scaling law: PEG45 (MW = 2100 Da) is an optimized MW to generate the most efficient renal clearance for IRDye800CW by expediting the glomerular filtration of organic dyes and reducing their nonspecific interactions with background tissue. Moreover, the uniqueness of PEG45 can be generalized to other organic dyes such as ZW800-1 and fluorescein.

Shaping of Metal-Organic Frameworks: From Fluid to Shaped Bodies and Robust Foams.

The applications of metal-organic frameworks (MOFs) toward industrial separation, catalysis, sensing, and some sophisticated devices are drastically affected by their intrinsic fragility and poor processability. Unlike organic polymers, MOF crystals are insoluble in any solvents and are usually not thermoplastic, which means traditional solvent- or melting-based processing techniques are not applicable for MOFs. Herein, a continuous phase transformation processing strategy is proposed for fabricating and shaping MOFs into processable fluids, shaped bodies, and even MOF foams that are capable of reversible transformation among these states.

A Solvent-Free Hot-Pressing Method for Preparing Metal-Organic-Framework Coatings.

Metal-organic frameworks (MOFs), with their well-defined pores and rich structural diversity and functionality, have drawn a great deal of attention from across the scientific community. However, industrial applications are hampered by their intrinsic fragility and poor processability. Stable and resilient MOF devices with tunable flexibility are highly desirable.
