The metabolome and lipidome lie closest to drug action, yet they have been among the slowest omics layers to adopt modern artificial intelligence. This paradox arises from their downstream position, which leaves them without a closed molecular reference and without the standardized, readily modeled data available to the genome and transcriptome. This review examines what these methods contribute to drug discovery and development. We survey applications across the drug-development pipeline, from target identification and mechanism-of-action deconvolution, through the prediction of drug-induced toxicity, to pharmacometabolomics, in which pre-dose metabolic phenotypes inform patient stratification and dosing. Across these metabolomic and lipidomic applications, interpretable classical machine learning remains the dominant form of artificial intelligence. The newer deep-learning and foundation models have concentrated instead on compound annotation, the cross-cutting problem of assigning confident identities to spectra, yet successive generations have mitigated but not solved it. Beyond annotation confidence, batch effects, semi-quantification, and small-cohort overfitting also remain practical constraints. Overall, targeted, hypothesis-driven metabolomic and lipidomic studies can already support drug discovery when their inferences are restricted to confidently identified metabolites, whereas open, hypothesis-free discovery remains the frontier. Near-term progress will depend less on any single algorithm than on curated spectral resources, rigorous measurement, leakage-aware validation, and honest reporting of identification confidence.</p>","PeriodicalId":8949,"journal":{"name":"Biomolecules & Therapeutics","volume":" ","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149126713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pathogenesis of thyroid cancer involves genetic mutations in BRAF, RAS, and RET, as well as dysregulated molecular pathways such as MAPK, PI3K/Akt/mTOR, and NF-κB, all of which contribute to cancer progression and therapeutic resistance. This review highlights how Traditional Chinese Medicine (TCM), with its extensive history and a diverse range of bioactive compounds derived from natural sources, offers a complementary approach to thyroid cancer treatment. TCM has been shown to modulate various cellular mechanisms, including inhibiting tumor proliferation, inducing apoptosis, and regulating immune responses. Additionally, TCM can influence the tumor microenvironment (TME), reducing immune evasion and improving therapeutic sensitivity. Many TCM compounds have been identified for their ability to target critical oncogenic signaling pathways, offering a holistic approach to cancer treatment with fewer side effects than traditional chemotherapy. Furthermore, integrating TCM with modern medicine, including novel formulations and nanotechnology, offers the potential to improve efficacy and reduce side effects.

To systematically map these epigenetic vulnerabilities, we utilized a genome-wide CRISPR interference library to screen wild-type <i>TP53</i> NSCLC (A549) cells under carboplatin selection. Using the DrugZ algorithm and subsequent pathway enrichment analyses, this screen revealed that transcriptional suppression of interstrand crosslink DNA repair networks, including the Fanconi anemia pathway, markedly sensitized cells to carboplatin. Unexpectedly, transcriptional silencing of <i>TP53</i> and its downstream target <i>CDKN1A</i> emerged as the strongest drivers of resistance, enabling cells to bypass therapy-induced senescence and maintain their proliferative potential later. To validate these findings in a clinically relevant context, we established a chronic carboplatin-resistant cell model (A549Carbo<sup>R</sup> cells).

Conversely, histone deacetylase inhibitors induced <i>CDKN1A</i> transcription to bypass <i>TP53</i>, indicating distinct epigenetic circuits. Collectively, the results demonstrate for the first time that <i>TP53</i> expression is dynamically regulated at the transcriptional level through promoter methylation related to the drug tolerance.
