Li R, Lu L, Huang Z, Gao Y. Downregulation of carbonic anhydrase IX expression in mouse xenograft nasopharyngeal carcinoma model via doxorubicin nanobubble combined with ultrasound. Open Med (Wars) 2024; 19:20240910. [PMID: 38463523 PMCID: PMC10921437 DOI: 10.1515/med-2024-0910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 01/19/2024] [Accepted: 01/22/2024] [Indexed: 03/12/2024] Open
Abstract
The purpose of this study was to investigate whether doxorubicin nanobubbles (DOX-NB) combined with diagnostic ultrasound (DUS) irradiation could downregulate the expression of carbonic anhydrase IX (CAIX) in mouse xenograft nasopharyngeal carcinoma (NPC) model. In this study, the prepared DOX-NB was round and well dispersed. The average diameter of DOX-NB was 250.9 ± 50.8 nm, with an average polydispersity of 0.321 ± 0.05. The cumulative release of DOX in the DOX-NB + DUS group was significantly higher compared with that of the DOX-NB group (p < 0.05). DOX-NB combined with DUS irradiation could significantly inhibit cell viability (p < 0.05). The expression of CAIX and microvessel density (MVD) in the xenografted tumors was the lowest in the DOX-NB + DUS group compared with that of other groups (p < 0.05). In conclusion, DOX-NB combined with DUS irradiation could improve DOX-NB drug release and synergistically inhibit NPC cell activity. DOX-NB combined with DUS irradiation can downregulate the expression of CAIX in mouse xenograft NPC model. This may be due to the synergistic effect of DUS combined with DOX-NB in reducing MVD in NPC.

Abstract
Brain metastasis of nasopharyngeal carcinoma (NPC) is a rare event with limited research. In this report, we discuss the details of a case of brain metastasis from NPC that presented with a solitary, cystic lesion in the frontal lobe. We also reviewed the related literature published in the last 20 years. We analyzed the patient's clinical characteristics, which indirectly suggested hematogenous spread rather than a cerebrospinal fluid route. Although there are no standard treatments for brain metastasis of NPC, previous studies reported that combined surgery and radiotherapy was a good treatment option, with long survival. Our patient achieved intracranial complete response after the combination of conventional chemoradiotherapy and novel immunotherapy. This treatment option could be useful in future similar cases.

Abstract
Carbonic anhydrases IX and CAXII (CAIX/CAXII) are transmembrane zinc metalloproteins that catalyze a very basic but crucial physiological reaction: the conversion of carbon dioxide into bicarbonate with a release of the proton. CA, especially CAIX and CAXII isoforms gained the attention of many researchers interested in anticancer drug design due to pivotal functions of enzymes in the cancer cell metastasis and response to hypoxia, and their expression restricted to malignant cells. This offers an opportunity to develop new targeted therapies with fewer side effects. Continuous efforts led to the discovery of a series of diverse compounds with the most abundant sulphonamide derivatives. Here we review current knowledge considering small molecule and antibody-based targeting of CAIX/CAXII in cancer.

Abstract
It reported that heat generated by near-infrared laser irradiation of gold nanorods (AuNRs) effectively inhibited tumor cells, and the conjugate of epidermal growth factor receptor monoclonal antibody (EGFRmAb) and gold nanorods could selectively binded to the surface of cancer cell membrane expressing EGFR. However, there are few research reports on EGFRmAb-AuNRs in laryngeal squamous cell carcinoma. Therefore, our study aimed to investigate the photothermal effect of EGFRmAb modified AuNRs in inducing tumor cell death in an animal model of laryngeal squamous cell carcinoma. We showed that the conjugates of EGFRmAb and AuNRs selectively entered laryngeal squamous cell carcinoma cells. We analyzed the parameters of laser irradiation by controlling the near-infrared to optimize the condition and procedure of targeted treatment in nude mice treated with EGFRmAb and AuNRs. In addition, we examined the safety of the combined therapy. Test results showed that EGFRmAb-AuNRs inhibited the growth of Hep-2 and CNE-2 cells but not normal epithelial cells, and the semi-inhibitor concentration of EGFRmAb in Hep-2 and CNE-2 cells was 4 pmol/ml and 2 pmol/ml, respectively. AuNRs injected into the tumor and irradiated by near-infrared laser effectively inhibited tumor growth in nude mice without toxic effect in mice. We further confirmed that the apoptosis and necrosis rates of tumor cells in mice were highest under 3 W/cm2 near-infrared laser irradiation and AuNRs minimum concentration of 280 μg/kg. In conclusion, we developed a new method of targeting EGFRmAb combined with AuNRs to achieve photothermal effect in the treatment of laryngeal squamous cell carcinoma.

Betulin Sulfonamides as Carbonic Anhydrase Inhibitors and Anticancer Agents in Breast Cancer Cells. Int J Mol Sci 2021; 22:ijms22168808.

Abstract
Hypoxia-regulated protein carbonic anhydrase IX (CA IX) is up-regulated in different tumor entities and correlated with poor prognosis in breast cancer patients. Due to the radio- and chemotherapy resistance of solid hypoxic tumors, derivatives of betulinic acid (BA), a natural compound with anticancer properties, seem to be promising to benefit these cancer patients. We synthesized new betulin sulfonamides and determined their cytotoxicity in different breast cancer cell lines. Additionally, we investigated their effects on clonogenic survival, cell death, extracellular pH, HIF-1α, CA IX and CA XII protein levels and radiosensitivity. Our study revealed that cytotoxicity increased after treatment with the betulin sulfonamides compared to BA or their precursors, especially in triple-negative breast cancer (TNBC) cells. CA IX activity as well as CA IX and CA XII protein levels were reduced by the betulin sulfonamides. We observed elevated inhibitory efficiency against protumorigenic processes such as proliferation and clonogenic survival and the promotion of cell death and radiosensitivity compared to the precursor derivatives. In particular, TNBC cells showed benefit from the addition of sulfonamides onto BA and revealed that betulin sulfonamides are promising compounds to treat more aggressive breast cancers, or are at the same level against less aggressive breast cancer cells.
