Abstract
The 'powerhouses' of cell, mitochondria have seen an upsurge of interest in investigations pertaining to the imaging and mapping of physiological processes. By utilizing sterol-modified rhodamine, we have performed the live-cell imaging of mitochondria without dependence on a membrane potential. The sterol probes are highly biocompatible, and they can track the mitochondrial live-cell dynamics in a background-free manner with improved brightness and impressive contrast. This is the first attempt to study the stress response using a direct fluorescence readout with bio-conjugates of rhodamine inside mitochondria. The results pave the way for developing different sterol markers for understanding cellular responses and function.

Abstract
A cholesterol silicon(IV) phthalocyanine (Chol-Pc) and a water-soluble Chol-Pc based nanoparticle (DSPE@Chol-Pc), which was prepared using 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(poly(ethylene glycol))-2000] (DSPE-PEG2000) as a nanocarrier were developed. Chol-Pc readily distributed within the cholesterol-rich domains and was preferentially localized in the Golgi apparatus after being transported into the cells. The trafficking of DSPE@Chol-Pc in breast cancer cells was visualized by tracking the fluorescence of Chol-Pc and FITC-labeled DSPE-PEG2000 through two-photonic imaging in real-time. It was discovered that Chol-Pc disassociated from the DSPE-PEG2000 on the plasma membrane and traveled to the cholesterol-rich domains soon afterward. Both DSPE@Chol-Pc and Chol-Pc effectively mediated photodynamic therapy to kill the breast cancer cells. After light irradiation, we found that the organizations of clustered cholesterol-rich domains in cells were destroyed, presumably leading to the death of cells for photodynamic therapy. It should be noted that DSPE@Chol-Pc is highly soluble in aqueous solution and has strong red fluorescence under two-photon excitation. Thus, it could be an excellent probe for detecting cholesterol-rich domains and studying transport processes of cholesterol in living cells.

Photodynamic Therapy Induced Enhancement of Tumor Vasculature Permeability Using an Upconversion Nanoconstruct for Improved Intratumoral Nanoparticle Delivery in Deep Tissues. Am J Cancer Res 2016; 6:1131-44. [PMID: 27279907 PMCID: PMC4893641 DOI: 10.7150/thno.15262] [Citation(s) in RCA: 67] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2016] [Accepted: 04/25/2016] [Indexed: 01/01/2023] Open
Abstract
Photodynamic therapy (PDT) has recently emerged as an approach to enhance intratumoral accumulation of nanoparticles. However, conventional PDT is greatly limited by the inability of the excitation light to sufficiently penetrate tissue, rendering PDT ineffective in the relatively deep tumors. To address this limitation, we developed a novel PDT platform and reported for the first time the effect of deep-tissue PDT on nanoparticle uptake in tumors. This platform employed c(RGDyK)-conjugated upconversion nanoparticles (UCNPs), which facilitate active targeting of the nanoconstruct to tumor vasculature and achieve the deep-tissue photosensitizer activation by NIR light irradiation. Results indicated that our PDT system efficiently enhanced intratumoral uptake of different nanoparticles in a deep-seated tumor model. The optimal light dose for deep-tissue PDT (34 mW/cm2) was determined and the most robust permeability enhancement was achieved by administering the nanoparticles within 15 minutes following PDT treatment. Further, a two-step treatment strategy was developed and validated featuring the capability of improving the therapeutic efficacy of Doxil while simultaneously reducing its cardiotoxicity. This two-step treatment resulted in a tumor inhibition rate of 79% compared with 56% after Doxil treatment alone. These findings provide evidence in support of the clinical application of deep-tissue PDT for enhanced nano-drug delivery.
