Abstract
To maximize therapeutic effects and minimize unwanted effects, the interest in drug targeting to the endoplasmic reticulum (ER) or Golgi apparatus (GA) has been recently growing because two organelles are distributing hubs of cellular building/signaling components (e.g., proteins, lipids, Ca2+) to other organelles and the plasma membrane. Their structural or functional damages induce organelle stress (i.e., ER or GA stress), and their aggravation is strongly related to diseases (e.g., cancers, liver diseases, brain diseases). Many efforts have been developed to image (patho)physiological functions (e.g., oxidative stress, protein/lipid-related processing) and characteristics (e.g., pH, temperature, biothiols, reactive oxygen species) in the target organelles and to deliver drugs for organelle disruption using organelle-targeting moieties. Therefore, this review will overview the structure, (patho)physiological functions/characteristics, and related diseases of the organelles of interest. Future direction on ER or GA targeting will be discussed by understanding current strategies and investigations on targeting, imaging/sensing, and therapeutic systems.

Abstract
Cationic polymers have recently attracted considerable interest as research breakthroughs for various industrial and biomedical applications. They are particularly interesting due to their highly positive charges, acceptable physicochemical properties, and ability to undergo further modifications, making them attractive candidates for biomedical applications. Polyethyleneimines (PEIs), as the most extensively utilized polymers, are one of the valuable and prominent classes of polycations. Owing to their flexible polymeric chains, broad molecular weight (MW) distribution, and repetitive structural units, their customization for functional composites is more feasible. The specific beneficial attributes of PEIs could be introduced by purposeful functionalization or modification, long service life, biocompatibility, and distinct geometry. Therefore, PEIs have significant potential in biotechnology, medicine, and bioscience. In this review, we present the advances in PEI-based nanomaterials, their transfection efficiency, and their toxicity over the past few years. Furthermore, the potential and suitability of PEIs for various applications are highlighted and discussed in detail. This review aims to inspire readers to investigate innovative approaches for the design and development of next-generation PEI-based nanomaterials possessing cutting-edge functionalities and appealing characteristics.

Pheophorbide a-mediated sonodynamic, photodynamic and sonophotodynamic therapies against prostate cancer. Photodiagnosis Photodyn Ther 2020; 31:101909.

Abstract
Anticancer efficiencies and mechanisms of Pheophorbide-a-mediated photodynamic, sonodynamic and sonophotodynamic therapies were investigated in vitro using androgen-sensitive (LNCaP) and androgen insensitive (PC3) prostate cancer cell lines. The cells were incubated in RPMI-1640 media at various concentrations of Pheophorbide-a. The media was treated with 0.5 W/cm2 ultrasound and/or 0.5 mJ/cm2 light irradiation. Cell proliferation in both cell lines was inhibited most effectively by sonophotodynamic therapy in comparison to that of both monotherapies. LNCaP cells were more sensitive to the applied treatments and the cell survival in LNCaP cell line was observed to be less than that of PC3 cell line. The results of histochemical analysis showed that there were more apoptotic cells in the treatment groups in comparison to control group. Additionally, the treatments induced apoptosis deduced by the overexpressed levels of caspase-3, caspase-8, PARP, and Bax proteins, while the expression levels of caspase-9 and Bcl-2 proteins were observed to be lower than those of control group. Treatments led to an increase in the oxidative stress markers, ROS and MDA, but a decrease in the activities of antioxidant enzymes, SOD, CAT and GSH. The results of this study revealed that Pheophorbide a-mediated sonophotodynamic therapy more efficiently activates the apoptotic mechanisms in prostate cancer cells and thus may provide a promising approach for treatment.

Abstract
Pharmacological interventions for effective treatment require opportune, dynamic and accurate manifestation of pathological status. Traditional clinical techniques relying on biopsy-based histological examinations and blood tests are dramatically restricted due to their invasiveness, unsatisfactory precision, non-real-time reporting and risk of complications. Although current strategies through molecular imaging enable non-invasive and spatiotemporal mapping of pathological changes in intact organisms, environment-activatable, sensitive and quantitative sensing platforms, especially for dynamic feedback of the therapeutic response, are still urgently desired in practice. Herein, we innovatively integrate deep-tissue penetrable multispectral optoacoustic tomography (MSOT) and near-infrared (NIR) optical imaging based technology by tailoring a free radical-responsive chromophore with photon-upconverting nanocrystals. During the therapeutic process, the specific reactions between the drug-stimulated reactive oxygen species (ROS) and radical-sensitive probes result in an absorption shift, which can be captured by MSOT. Meanwhile, the radical-triggered reaction also induces multispectral upconversion luminescence (UCL) responses that exhibit the opposite trend in comparison to MSOT. Such reversed-ratiometric dual-modal imaging outcomes provide an ideal cross-referencing system that guarantees the maximum sensing specificity and sensitivity, thus enabling precise disease biology evaluation and treatment assessments in vivo.

Abstract
Lymphatic metastasis is the major metastatic pattern of pancreatic cancer and considered as an independent risk factor of survival. However, there is still no effective way for the diagnosis and treatment for lymphatic metastases of pancreatic cancer. In this study, using albumin as a carrier of gemcitabine (Gem), further modified by pyropheophorbide-a, we have designed and synthesized a nanoparticle (NP) compound named "pheophorbide-a (P@)-Gem-human serum albumin (HSA)-NPs". By utilization of its tracer ability of lymphatic metastases, which is triggered by near-infrared irradiation and its visible dying ability, the compound is used for drug delivery tracking, meanwhile as a treating drug, as well as the combined effect of photodynamic therapy and chemotherapy. By the nude mice model of lymphatic metastases of pancreatic cancer (BxPC-3-LN7), we aim to explore the feasibility, effectiveness, and biological safety of diagnosis and treatment for the lymphatic metastases of pancreatic cancer by P@-Gem-HSA-NP, thereby, providing new methods and strategies for the study of nanodrug carrier and research on lymphatic metastases of pancreatic cancer.

Abstract
The clinical application of intracellular gene delivery via nanosized carriers is hindered by intracellular multistep barriers that limit high levels of gene expression. To solve these issues, four different intracellular or external stimuli that can efficiently activate a gene carrier, a gene, or a photosensitizer (pheophorbide A [PhA]) were assessed in this study. The designed nanosized polymeric gene complexes were composed of PhA-loaded thiol-degradable polycation (PhA@RPC) and cytomegalovirus (CMV) promoter-equipped pDNA. After cellular internalization of the resulting PhA@RPC/pDNA complexes, the complexes escaped endosomal sequestration, owing to the endosomal pH-induced endosomolytic activity of RPC in PhA@RPC. Subsequently, intracellular thiol-mediated polycation degradation triggered the release of PhA and pDNA from the complexes. Late exposure to light (for example, 12 h post-treatment) activated the released PhA and resulted in the production of reactive oxygen species (ROS). Intracellular ROS successively activated NF-κB, which then reactivated the CMV promoter in the pDNA. These sequential, stimuli-responsive chemical and biological reactions resulted in high gene expression. In particular, the time-point of light exposure was very significant to tune efficient gene expression as well as negligible cytotoxicity: early light treatment induced photochemical internalization but high cytotoxicity, whereas late light treatment influenced the reactivation of silent pDNA via PhA-generated ROS and activation of NF-κB. In conclusion, the quadruple triggers, such as pH, thiol, light, and ROS, successively influenced a gene carrier (RPC), a photosensitizer, and a genetic therapeutic, and the tempo-spatial activation of the designed quadruple stimuli-activatable nanosized gene complexes could be potential in gene delivery applications.

Abstract
Mitochondria-targeting drug carriers have considerable potential because of the presence of many molecular drug targets in the mitochondria and their pivotal roles in cellular viability, metabolism, maintenance, and death. To compare the mitochondria-targeting abilities of triphenylphosphonium (TPP) and pheophorbide a (PhA) in nanoparticles (NPs), this study prepared mitochondria-targeting NPs using mixtures of methoxy poly(ethylene glycol)-(SS-PhA)2 [mPEG-(SS-PhA)2 or PPA] and TPP-b-poly(ε-caprolactone)-b-TPP [TPP-b-PCL-b-TPP or TPCL], which were designated PPAn-TPCL4-n (0≤n≤4) NPs. With increasing TPCL content, the formed PPAn-TPCL4-n NPs decreased in size from 33nm to 18nm and increased in terms of positive zeta-potentials from -12mV to 33mV. Although the increased TPCL content caused some dark toxicity of the PPAn-TPCL4-n NPs due to the intrinsic positive character of TPCL, the NPs showed strong light-induced killing effects in tumor cells. In addition, the mitochondrial distribution of the PPAn-TPCL4-n NPs was analyzed and imaged by flow cytometry and confocal microscopy, respectively. Thus, the PhA-containing NPs specifically targeted the mitochondria, and light stimulation caused PhA-mediated therapeutic effects and imaging functions. Expanding the capabilities of these nanocarriers by incorporating other drugs should enable multiple potential applications (e.g., targeting, therapy, and imaging) for combination and synergistic treatments.

Abstract
A peptide composed of lysine with a guanidinylethyl (GEt) amine structure in the side chain [Lys(GEt)] was developed as a cell-penetrating peptide directed to plasmid DNA (pDNA) delivery. The GEt amine adopted a diprotonated form at neutral pH, which may have led to the more efficient cellular uptake of a Lys(GEt)-peptide than an arginine-peptide at a low concentration. Lys(GEt)-peptide/pDNA complexes showed the highest transfection efficiency due to efficient endosomal escape without any cytotoxicity. Lys(GEt)-peptide may be a promising candidate as a gene delivery carrier.

Herein, a cancer-recognizing polymeric photosensitizer (CRPP) was demonstrated not only for high water solubility but also for pH-responsive targeted photodynamic cancer therapy. The synthesized CRPP exhibited high water solubility and the pH-dependent charge-switching property. From an in vitro cellular internalization study with HCT-116 human colon cancer cells, significantly enhanced cellular uptake as detected for CRPP at pH 6.5 compared to the cellular uptake of CRPP at pH 7.4, which led to enhanced cytotoxicity in the cancer cells. Finally, the CRPP was found to exhibit high tumor-targeting efficacy in an in vivo tumor model and was finally excreted through the renal route.
