Evaluation of photodynamic effect of Indocyanine green (ICG) on the colon and glioblastoma cancer cell lines pretreated by cold atmospheric plasma

Nucleolin-targeted doxorubicin and ICG co-loaded theranostic lipopolymersome for photothermal-chemotherapy of melanoma in vitro and in vivo

Combination therapy using chemo-photothermal therapy (chemo-PTT) shows great efficacy toward tumor ablation in preclinical studies. Besides, lipopolymersomes as a hybrid nanocarriers, integrate advantages of liposomes and polymersomes in a single platform in order to provide tremendous biocompatibility, biodegradability, noteworthy loading efficacy for both hydrophobic and hydrophilic drugs with adjustable drug release and high stability. In this study, a multipurpose lipopolymersome was fabricated for guided chemotherapy-PTT and NIR-imaging of melanoma. A lipopolymerosomal hybrid nanovesicle consisting of equal molar ratio of 1,2-dioleoyl-3-trimethylammonium propane (DOTAP) and poly (ethylene glycol)-poly (lactic acid) (PEG-PLA) diblock copolymer (molar ratio 1:1) was fabricated. The nanoparticulate system was prepared through film rehydration technique for encapsulation of doxorubicin (DOX) and indocyanine green (ICG) to form DOX-ICG-LP platform. At the next stage, AS1411 DNA aptamer was conjugated to the surface of lipopolymersome (Apt-DOX-ICG-LP) for selective delivery. The sizes of DOX-ICG-LP and Apt-DOX-ICG-LP were obtained through DLS analysis (61.0 ± 6 and 74 ± 5, respectively). Near Infrared-responsive release pattern of the prepared lipopolymersome was verified in vitro. The formulated platform showed efficient photothermal conversion, and superior stability with acceptable encapsulation efficiency. Consistent with the in vitro studies, NIR-responsive lipopolymersome exhibited significantly higher cellular toxicity for Chemo-PTT versus single anti-cancer treatment. Moreover, superlative tumor shrinkage with favorable survival profile were attained in B16F10 tumor-bearing mice received Apt-DOX-ICG-LP and irradiated with 808 nm laser compared to those treated with either DOX-ICG-LP or Apt-DOX-ICG-LP without laser irradiation. The diagnostic capability of Apt-DOX-ICG-LP was addressed using in vivo NIR imaging, 6 and 24 h post-intravenous administration. The results indicated desirable feature of an established targeted theranostic capability of Apt-DOX-ICG-LP for both diagnostics and dual chemo-PTT of melanoma.

Current Status and Future Trends of Cold Atmospheric Plasma as an Oncotherapy

Cold atmospheric plasma (CAP), a redox modulation tool, is capable of inhibiting a wide spectrum of cancers and has thus been proposed as an emerging onco-therapy. However, with incremental successes consecutively reported on the anticancer efficacy of CAP, no consensus has been made on the types of tumours sensitive to CAP due to the different intrinsic characteristics of the cells and the heterogeneous design of CAP devices and their parameter configurations. These factors have substantially hindered the clinical use of CAP as an oncotherapy. It is thus imperative to clarify the tumour types responsive to CAP, the experimental models available for CAP-associated investigations, CAP administration strategies and the mechanisms by which CAP exerts its anticancer effects with the aim of identifying important yet less studied areas to accelerate the process of translating CAP into clinical use and fostering the field of plasma oncology.

Multiple therapeutic approaches of glioblastoma multiforme: From terminal to therapy

Glioblastoma multiforme (GBM) is an aggressive brain cancer showing poor prognosis. Currently, treatment methods of GBM are limited with adverse outcomes and low survival rate. Thus, advancements in the treatment of GBM are of utmost importance, which can be achieved in recent decades. However, despite aggressive initial treatment, most patients develop recurrent diseases, and the overall survival rate of patients is impossible to achieve. Currently, researchers across the globe target signaling events along with tumor microenvironment (TME) through different drug molecules to inhibit the progression of GBM, but clinically they failed to demonstrate much success. Herein, we discuss the therapeutic targets and signaling cascades along with the role of the organoids model in GBM research. Moreover, we systematically review the traditional and emerging therapeutic strategies in GBM. In addition, we discuss the implications of nanotechnologies, AI, and combinatorial approach to enhance GBM therapeutics.

Application and prospect of ROS-related nanomaterials for orthopaedic related diseases treatment

The importance of reactive oxygen species (ROS) in the occurrence and development of orthopaedic related diseases is becoming increasingly prominent. ROS regulation has become a new method to treat orthopaedic related diseases. In recent years, the application of nanomaterials has become a new hope for precision and efficient treatment. However, there is a lack of reviews on ROS-regulated nanomaterials for orthopaedic related diseases. Based on the key significance of nanomaterials for the treatment of orthopaedic related diseases, we searched the latest related studies and reviewed the nanomaterials that regulate ROS in the treatment of orthopaedic related diseases. According to the function of nanomaterials, we describe the scavenging of ROS related nanomaterials and the generation of ROS related nanomaterials. In this review, we closely integrated nanomaterials with the treatment of orthopaedic related diseases such as arthritis, osteoporosis, wound infection and osteosarcoma, etc., and highlighted the advantages and disadvantages of existing nanomaterials. We also looked forward to the design of ROS-regulated nanomaterials for the treatment of orthopaedic related diseases in the future.
