3,4-Dihydroxyphenylalanine (DOPA) has inspired the development of artificial adhesives, but efforts to enhance its adhesion strength and durability continue to evolve. However, it is tough work to improve DOPA wet adhesion by chemically decorating DOPA itself, despite the potential benefit of a concise and high-quality adhesion unit. Here, we synthesized a series of DOPA substituents by introducing different electron-withdrawing groups at the ortho position of the phenyl ring.

Accurate drug-target binding affinity (DTA) prediction is crucial in drug discovery. Recently, deep learning methods for DTA prediction have made significant progress. However, there are still two challenges: (1) recent models always ignore the correlations in drug and target data in the drug/target representation process and (2) the interaction learning of drug-target pairs always is by simple concatenation, which is insufficient to explore their fusion.

Papillary thyroid microcarcinoma (PTMC), although frequently indolent, could be aggressive in a few patients, leading to lymph node metastasis (LNM) and worsened prognosis. To explore the role of protein profiling of small extracellular vesicles (sEVs) in the auxiliary diagnosis and risk stratification of PTMC, proteins in serum sEVs isolated from PTMC patients with (N = 10) and without (N = 10) LNM and benign thyroid nodule (BN) patients (N = 9) were profiled via a bioinformatics-integrated data-independent acquisition proteomic technique. The performance of candidate proteins as diagnostic and prognostic biomarkers in PTMC was assessed via receiver operating characteristic analysis.

Currently, the main therapeutic methods for cancer include surgery, radiation therapy, and chemotherapy. However, chemotherapy still plays an important role in tumor therapy. Due to the variety of pathogenic factors, the development process of tumors is complex and regulated by many factors, and the treatment of a single drug is easy to cause the human body to produce a drug-resistant phenotype to specific drugs and eventually leads to treatment failure.

To target the reactive oxygen species (ROS) accumulation and renal tubular epithelial cell (rTEC) death in renal ischemia-reperfusion injury (IRI), we constructed a nanoparticle that offers ROS scavenging and rTEC-death inhibition: mesoporous zinc-tannic acid nanozyme (ZnTA). After successfully constructing ZnTA, we proceeded to examine its effect on ROS accumulation, cellular ferroptosis and apoptosis, as well as injury severity. Malondialdehyde, Fe amounts and 4-HNE staining demonstrated that ZnTA effectively attenuated rTEC ferroptosis.

Article Synopsis
  • DUSP26 is an important protein that helps protect kidney cells from damage when blood flow is restored after being cut off.
  • Researchers found that when DUSP26 levels are low, kidney cells are more likely to get hurt from lack of oxygen (like in kidney ischaemia), but increasing DUSP26 protects the kidney from this damage.
  • This study suggests that DUSP26 could be a potential target for new treatments to help people with kidney injuries caused by blood flow issues.
