Esophageal cancer is one of the leading causes of cancer death in the world,with approximately half of the new cases occurring in China every year.^(1)Esophageal squamous cell carcinoma(ESCC)is the main subtype,accounting for more than 90%,and the five-year survival rate is less than 10%.Using large-scale genome analysis,many driver mutations and key pathways associated with ESCC have been ***,these genomic signatures have not improved the clinical management of EscC patients,or established effective targeted therapy.^(2)Esophageal cancer still lacks representative molecular markers.

Drug-target interactions(DTIs) prediction plays an important role in the process of drug *** computational methods treat it as a binary prediction problem, determining whether there are connections between drugs and targets while ignoring relational types information. Considering the positive or negative effects of DTIs will facilitate the study on comprehensive mechanisms of multiple drugs on a common target, in this work, we model DTIs on signed heterogeneous networks, through categorizing interaction patterns of DTIs and additionally extracting interactions within drug pairs and target protein pairs. We propose signed heterogeneous graph neural networks(SHGNNs), further put forward an end-to-end framework for signed DTIs prediction, called SHGNN-DTI,which not only adapts to signed bipartite networks, but also could naturally incorporate auxiliary information from drug-drug interactions(DDIs) and protein-protein interactions(PPIs). For the framework, we solve the message passing and aggregation problem on signed DTI networks, and consider different training modes on the whole networks consisting of DTIs, DDIs and PPIs. Experiments are conducted on two datasets extracted from Drug Bank and related databases, under different settings of initial inputs, embedding dimensions and training modes. The prediction results show excellent performance in terms of metric indicators, and the feasibility is further verified by the case study with two drugs on breast cancer.

We must urgently synthesize highly efficient and stable oxygen-evolution reaction（OER） catalysts for acidic media. Herein, we constructed a series of Ti mesh（TM）-supported RuO2/CoMoyOxcatalysts（RuO2/CoMoyOx/TM） with heterogeneous structures. By optimizing the ratio of Co to Mo, RuO2/CoMo2Ox/TM with low Ru loading（0.079 mg/cm2） achieves remarkable OER performance（ η = 243 mV at 10 mA/cm2） and high stability（300 h @ 10 mA/cm2） in 0.5 mol/L H 2 SO 4 electrolyte. The activity of RuO2/CoMoyOx/TM can be maintained for 50 h at 100 mA/cm2, and a water electrolyzer with RuO2/CoMo2Ox/TM as anode can operate for 40 h at 100 mA/cm2, suggesting the remarkable OER durability of RuO2/CoMoyOx/TM in acidic electrolyte. Owing to the heterogeneous interface between CoMo2Oxand RuO2, the electronic structure of Ru atoms was optimized and electron-rich Ru was formed. With modulated electronic properties, the dissociation energy of H2O is weakened, and the OER barrier is lowered. This study provides the design of low-cost noble metal catalysts with long-term stability in an acidic environment.
