Abstract
This study investigated the ability of cholesterol-phosphatidylcholine liposomes loaded with chloride aluminum phthalocyanine (CL-AlClPc) to discriminate between healthy (MCF-10A) and neoplastic (MCF-7 and MDA-MB-231) breast cells for breast cancer diagnosis and treatment by photodynamic therapy (PDT) using a new drug delivery system consisting of CL-AlClPc. When PDT treatment was applied at an energy fluence of 700 mJ/cm², CL-AlClPc was more cytotoxic to neoplastic cells than to healthy breast cells because CL-AlClPc was better internalized by the tumor cells. An even higher fluorescence signal is expected for neoplastic cells during clinical treatment than for healthy cells, which will be useful for precise and targeted tumor cell detection. CL-AlClPc also facilitated better drug distribution and targeting of essential organelles inside the cells. This selectivity is critical for future in vivo diagnosis and treatment; it prevents side effects because it prioritizes tumor cells and tissues instead of healthy ones. The CL-AlClPc system designed herein had a small size (150 nm), low zeta potential (-6 mV), low polydispersity (0.16), high encapsulation rate efficiency (82.83%), and high shelf stability (12 months).

Jayme CC, Pires AF, Fernandes DS, Bi H, Tedesco AC. DNA polymer films used as drug delivery systems to early-stage diagnose and treatment of breast cancer using 3D tumor spheroids as a model. Photodiagnosis Photodyn Ther 2021; 37:102575. [PMID: 34628073 DOI: 10.1016/j.pdpdt.2021.102575] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 09/09/2021] [Accepted: 10/04/2021] [Indexed: 12/31/2022]
Abstract
The present study examines the designer of DNA polymeric films (DNA-PFs) associated with aluminum chloride phthalocyanine (AlClPc) (DNA-PFs-AlClPc), as a promising drug delivery system (DDS), applicable for breast cancer treatment and early-stage diagnosis using photodynamic therapy (PDT). This study starts evaluating (MCF7) as a model for breast cancer cell behavior associated with DNA-PFs. Analyses of the morphological behaviors, biochemical reaction, and MCF7 cell adhesion profile on DNA-PFs were evaluated. SEM and AFM analysis allowed the morphological characterization of the DNA-PFs. Cell viability and cell cycle kinetics studies indicate highly biocompatible material capable of anchoring MCF7 cells, allowing the attachment and support of cell in the same structure where the insertion of AlClPc (DNA-PFs-AlClPc). The application of visible light photoactivation based on classical PDT protocol over the DNA-PFs-AlClPc showed a reduction in cell viability with increased cell death proportional to the fluency energy range from 600, 900, and 1800 mJ cm-2. The 3D organoid system mimics the tumor microenvironment which was precisely observed in human breast cancer in early-stage progression in the body. The results observed indicate that the viability was reduced by more than 80% in monolayer culture and around 50% in the 3D organoid cell culture at the highest energy fluency (1800 mJ cm-2). We could also point out that with low energy fluency (100 mJ cm-2,), the DNA-PFs-AlClPc did not show a cytotoxic effect on MCF7 cells, enabling this user dose for the photodiagnosis of early-stage human breast cancer detection in the initial stage of progression.
