Although most cancer drugs modulate the activities of cellular pathways by changing posttranslational modifications (PTMs), little is known regarding the extent and the time- and dose-response characteristics of drug-regulated PTMs. In this work, we introduce a proteomic assay called decryptM that quantifies drug-PTM modulation for thousands of PTMs in cells to shed light on target engagement and drug mechanism of action. Examples range from detecting DNA damage by chemotherapeutics, to identifying drug-specific PTM signatures of kinase inhibitors, to demonstrating that rituximab kills CD20-positive B cells by overactivating B cell receptor signaling. DecryptM profiling of 31 cancer drugs in 13 cell lines demonstrates the broad applicability of the approach. The resulting 1.8 million dose-response curves are provided as an interactive molecular resource in ProteomicsDB.

Liver cancer is the fourth most deadly cancer worldwide, but existing treatment options are insufficient, thus highlighting the urgent need for new therapeutic agents. Taxanes, known for their anticancer properties, provide a promising avenue for intervention. In this study, a tetracyclic taxane compound with antitumor activity (taxinine) was extracted and isolated from Taxus chinensis (T.

Although traditional immunogenic cell death (ICD) inducers generate vaccines (ISV) to potentiate antiprogrammed cell death ligand 1 (anti-PDL1) antibodies therapy, their efficacy remains limited. This limitation may be attributed to the physical barrier created by extracellular matrix (ECM) and immunosuppressive metabolic barrier mediated by adenosine. Here, we report an oncolytic polymer (OP), a well-designed ε-polylysine derivative with ICD-inducing capacity, which can simultaneously facilitate the release of endogenous ECM-degrading enzyme, Cathepsin B.

Cancer treatment faces challenges like nonselective toxicity and drug resistance, prompting the need for innovative therapies. This study aimed to develop liposomal formulations for co-delivery of empagliflozin and rutin, evaluating their anticancer and antioxidant efficacy. PEGylated empagliflozin-loaded nanoliposomes (Empa-NLs) and empagliflozin-rutin co-loaded nanoliposomes (Empa-Rut NLs) were synthesized using the thin-film hydration technique.

Introduction: Colorectal cancer (CRC) is a prevalent malignant tumor of the digestive tract. The FOLFOX regimen (oxaliplatin + calcium folinate + 5-fluorouracil) serves as the primary treatment for advanced CRC clinically, yet its application is significantly limited by substantial toxic side effects. Erianin, a natural compound from Chinese medicine Lindl, demonstrates significant potential in both tumor growth inhibition and chemotherapy toxicity reduction.
