High-risk neuroblastoma continues to show a very high mortality, with a 5-year survival rate of 50%. While MYCN amplification is the main genetic alteration associated with high-risk tumours, other molecular mechanisms, such as alterations in ATRX and TERT, remain poorly understood. ATRX and TERT biomarkers, which are associated with a more aggressive neuroblastoma pattern, should be considered for accurate prognostic stratification. We highlight the promising results of the clinical trial involving the combination of adavosertib and irinotecan, which encourages further clinical trials with adavosertib targeting NB with ATRX mutations. Preclinical results with BET inhibitors (OTX015 and AZD5153) and with 6-thio-2'-deoxyguanosine, targeting NB with TERT mutations, are promising. Both represent future therapeutic targets, emphasizing the need to prioritize research using these models.

Symptoms of ulcerative colitis (UC) are like "intestinal carbuncle" in Chinese medicine. The aqueous extract of Sargentodoxa cuneata (AESc) has good therapeutic effects on UC, but the underlying mechanism needs to be further elucidated. The mechanism of AESc against UC was studied based on metabolomics and bioinformatics in mice with UC. Dextran sodium sulfate was applied to induce a mouse model of UC. After the intervention of AESc, the general condition of the animals was recorded, and efficacy-related indicators were measured. Information on serum metabolites was determined. Multivariate analysis combined with bioinformatics methods were used to identify the differential metabolites. Furthermore, "metabolite-target-disease" network was obtained, and differential metabolites of UC were screened, and further analysis of the metabolites were performed. Molecular docking validation was also carried out. AESc improved general conditions such as blood in stool, hair of animals, and weight loss, reduced disease activity index scores and shortening of colon length in mice with UC. A total of 3445 serum metabolites were obtained, and 64 differentiated metabolites of AESc against UC were screened. Enrichment analysis showed that arachidonic acid metabolism, bile secretion, drug metabolism-other enzymes, and tyrosine metabolism were associated with AESc in the treatment of UC. In addition, based on "metabolite-target-disease" network, the serum metabolites cholylleucine, 9,10,13-TriHOME, birabresib, anthramycin methyl ether, trans-hexadec-2-enoyl carnitine, and lucidumol A were found to have the therapeutic potential for UC. Further, 14 core targets were obtained, and lipids and atherosclerosis, rheumatoid arthritis and multiple immune-inflammatory pathways were associated with AESc for the treatment of UC. AESc corrects serum metabolic disturbances in UC mice, and multiple serum metabolites have therapeutic potential for UC. AESc may treat UC by regulating biological processes such as lipid metabolism, amino acid metabolism, thereby restoring normal physiological function of the intestine.
