<p>A. Tumor volume was measured after USP42 siRNA (siRNA) or siRNA control (siNC) injection. B. Mice were sacrificed and tumors were recovered at 36 days after tumor placement. The pictures (upper panel) and weight (n = 6, expressed as mean ± SD, lower panel) of recovered tumors were shown. C. The expression of USP42 and PCNA in tumors from the nude mice was determined by western blot. * <i>P</i><0.05, ** <i>P</i><0.01, *** <i>P</i><0.001 compared with siNC.</p
Nature-Inspired Strategy toward Superhydrophobic Fabrics for Versatile Oil/Water Separation
Phytic
acid, which is a naturally occurring component that is widely
found in many plants, can strongly bond toxic mineral elements in
the human body, because of its six phosphate groups. Some of the metal
ions present the property of bonding with phytic acid to form insoluble
coordination complexes aggregations, even at room temperature. Herein,
a superhydrophobic cotton fabric was prepared using a novel and facile
nature-inspired strategy that introduced phytic acid metal complex
aggregations to generate rough hierarchical structures on a fabric
surface, followed by PDMS modification. This superhydrophobic surface
can be constructed not only on cotton fabric, but also on filter paper,
polyethylene terephthalate (PET) fabric, and sponge. Ag<sup>I</sup>, Fe<sup>III</sup>, Ce<sup>III</sup>, Zr<sup>IV</sup>, and Sn<sup>IV</sup> are very commendatory ions in our study. Taking phytic acid–Fe<sup>III</sup>-based superhydrophobic fabric as an example, it showed
excellent resistance to ultraviolet (UV) irradiation, high temperature,
and organic solvent immersion, and it has good resistance to mechanical
wear and abrasion. The superhydrophobic/superoleophilic fabric was
successfully used to separate oil/water mixtures with separation efficiencies
as high as 99.5%. We envision that these superantiwetting fabrics,
modified with phytic acid–metal complexes and PDMS, are environmentally
friendly, low cost, sustainable, and easy to scale up, and thereby
exhibit great potentials in practical applications
Correlation of USP42 expression with patients’ features in gastric cancer.
<p>Correlation of USP42 expression with patients’ features in gastric cancer.</p
USP42 was important for GC cell viability.
<p>A. USP42 protein levels were determined in diverse GC cell lines by Western blot and normalized to GAPDH. B. USP42 silencing efficiency of siRNA transfection in AGS and MKN-45 cells was evaluated by Western blot. C. USP42 silencing by siRNA transfection resulted in growth inhibition as detected by CCK-8 assay in AGS and MKN-45 cells. Cells transfected with USP42 siRNA or non-silencing siRNA (siNC) for 48h, along with non-treated cells, were seeded in a 96-well plates, and cell viability was determined at indicated time points. * <i>P</i><0.05, ** <i>P</i><0.01, *** <i>P</i><0.001 compared with siNC.</p
USP42 silencing inhibited cell invasion.
<p>A. GSEA analysis in GC patients with higher USP42 expression versus lower USP42 expression based on TCGA datasets. Cell metastasis pathway was associated with USDP42-higher expression. The enrichment score (ES, green line) reflects the correlation between metastasis pathway and the sample. Black bars indicate previously known genes associated with cell metastasis pathway. B. USP42 silencing decreased cell invasion as detected by in vitro invasion assay. C, D. Expression of key proteins in metastasis and EMT was determined by western blot. * <i>P</i><0.05, ** <i>P</i><0.01, *** <i>P</i><0.001 compared with siNC.</p

USP42 silencing induced G0/G1 phase arrest.
<p>A. GSEA analysis in GC patients with higher USP42 expression versus lower USP42 expression based on TCGA datasets. KEGG cell cycle pathway was associated with USDP42-higher expression.

Matchstick-Like Cu<sub>2</sub>S@Cu<sub><i>x</i></sub>O Nanowire Film: Transition of Superhydrophilicity to Superhydrophobicity
We
fabricated a matchstick-like Cu<sub>2</sub>S@Cu<sub><i>x</i></sub>O nanowire film on copper mesh by applying a CuÂ(OH)<sub>2</sub> nanowires template-sacrificial method, which can transformed
from superhydrophilic to superhydrophobic just after storage in air
for a certain period without any further organic modification. The
surface morphology, chemical composition and the wettability were
investigated by Scanning Electron Microscopy (SEM), X-ray diffractometer
(XRD), Raman, X-ray Photoelectron Microscopy (XPS), and contact angle
measurement. Results showed that the change of surface chemical composition
and the trapped air among the matchstick-like structures were the
decisive factors for the wettability transition. Therefore, on-demand
oil/water separation was achieved, which was performed by using the
superhydrophilic–underwater superoleophobic mesh for separating
light oil/water mixtures and the superhydrophobic one for separating
heavy oil/water mixtures
