N-methyladenosin (mA) is one of the most pervasive modification of mRNA in eukaryotes and the mA methyltransferases and demethylases play critical roles in many types of cancer. However the role of mA-binding proteins in cancer remains elusive. Here we report that the down-regulation of YTHDF2 was specifically induced by hypoxia in hepatocellular carcinoma (HCC) cells, and that overexpression of YTHDF2 suppressed cell proliferation, tumor growth and activation of MEK and ERK in HCC cells. Mechanistically, YTHDF2 directly bound the mA modification site of EGFR 3'-UTR to promote the degradation of EGFR mRNA in HCC cells. This is the first report showing that YTHDF2 may act as a tumor suppressor to repress cell proliferation and growth via destabilizing the EGFR mRNA in HCC.

Zinc (Zn) and its alloys are promising biomaterials for orthopedic applications due to their degradability and mechanical properties. Zn plays a crucial role in bone formation, but excessive early release may cause cytotoxicity and inhibit osseointegration. To solve this, we developed a near-infrared (NIR) light-controlled polycaprolactone/copper-sulfur (PCL/CuS) coating that slows degradation and enhances osseointegration of Zn alloys.

As solute carriers (SLC) transporters are capable of transporting different amino acids, cancer may develop as a result of these transporters' over-expression due to their complex formation with other biological molecules. Therefore, this review investigated the role of SLC transporters in the progression of cancer.

Background/purpose: Titanium dioxide nanotube (TNT) structures have been shown to enhance the early osseointegration of dental implants. Nevertheless, the optimal nanotube diameter for promoting osteogenesis remains unclear due to variations in cell types and manufacture of nanotubes. This study aimed to evaluate the differences in MC3T3-E1 and Saos-2 cells behavior on nanotubes of varying diameters.

The CDKN2A gene, responsible for encoding the tumor suppressors p16(INK4A) and p14(ARF), is frequently inactivated in non-small cell lung cancer (NSCLC). Herein, an uncharacterized long non-coding RNA (lncRNA) (ENSG00000267053) on chromosome 19p13.12 was found to be overexpressed in NSCLC cells with an active, wild-type CDKN2A gene.

Inducing the degradation of KRAS represents a novel strategy to combat cancers with KRAS mutation. In this study, we identify ubiquitin-specific protease 2 (USP2) as a novel deubiquitinating enzyme of KRAS in multiple myeloma (MM). Specifically, we demonstrate that gambogic acid (GA) forms a covalent bond with the cysteine 284 residue of USP2 through an allosteric pocket, inhibiting its deubiquitinating activity.
