Abstract
Taxanes, particularly docetaxel (DTX), has been widely used for combination therapy of head and neck squamous cell carcinoma (HNSCC). For locally advanced unresectable HNSCC, DTX combined with cisplatin and 5-fluorouracil as a revolutionary treatment revealed an advantage in the improvement of patient outcome. In addition, DTX plus immune check inhibitors (ICIs) showed low toxicity and an increased response of patients with recurrent or metastatic HNSCC (R/M HNSCC). Accumulated data indicate that taxanes not only function as antimitotics but also impair diverse oncogenic signalings, including angiogenesis, inflammatory response, ROS production, and apoptosis induction. However, despite an initial response, the development of resistance remains a major obstacle to treatment response. Taxane resistance could result from intrinsic mechanisms, such as enhanced DNA/RNA damage repair, increased drug efflux, and apoptosis inhibition, and extrinsic effects, such as angiogenesis and interactions between tumor cells and immune cells. This review provides an overview of taxanes therapy applied in different stages of HNSCC and describe the mechanisms of taxane resistance in HNSCC. Through a detailed understanding, the mechanisms of resistance may help in developing the potential therapeutic methods and the effective combination strategies to overcome drug resistance.

Exploring pradimicin-IRD antineoplastic mechanisms and related DNA repair pathways. Chem Biol Interact 2023; 371:110342. [PMID: 36634904 DOI: 10.1016/j.cbi.2023.110342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 12/24/2022] [Accepted: 01/05/2023] [Indexed: 01/11/2023]
Abstract
DNA-targeting agents have a significant clinical use, although toxicity remains an issue that plays against their widespread application. Understanding the mechanism of action and DNA damage response elicited by such compounds might contribute to the improvement of their use in anticancer chemotherapy. In a previous study, our research group characterized a new DNA-targeting agent - pradimicin-IRD. Since DNA-targeting agents and DNA repair are close-related subjects, the present study used in silico-modelling and a transcriptomic approach seeking to characterize the DNA repair pathways activated in HCT 116 cells following pradimicin-IRD treatment. Molecular docking analysis showed pradimicin-IRD as a DNA intercalating agent and a potential inhibitor of DNA-binding proteins. Furthermore, the transcriptomic study highlighted DNA repair functions related to genes modulated by pradimicin-IRD, such as nucleotide excision repair, telomeres maintenance and double-strand break repair. When validating these functions, PCNA protein levels decreased after exposure to pradimicin. Furthermore, molecular docking analysis suggested DNA-pradimicin-PCNA interaction. In addition, hTERT and POLH showed reduced mRNA levels after 6 h of treatment with pradimicin-IRD. Moreover, POLH-deficient cells displayed higher resistance to pradimicin-IRD than POLH-proficient cells and the compound prevented formation of the POLH/DNA complex (molecular docking). Since the modulation of DNA repair genes by pradimicin-IRD is TP53-independent, unlike doxorubicin, dissimilarities between the mechanism of action and the DNA damage response of pradimicin-IRD and doxorubicin open new insights for further studies of pradimicin-IRD as a new antineoplastic compound.
