Cancer Theranostics

Nanomedicine is widely developed in recent years. In nanomedicine system, nanoscale and nanostructured functional materials are used to manipulate the human biology systems at the molecular level for cancer imaging and therapy. New nanostructure based functional materials consist of nanoscale liposomes, spheres, micelles, capsules, emulsion, suspension and phamacosomes. Several functional nanoparticles such as lipidbased and polymer-based materials are demonstrated to be drug delivery vehicles and imaging agents. These materials are biodegradable, biocompatible and have better biodistribution, lower side effect and lower toxicity. In addition, hybrids with these materials coating provide uniquely electrical, optical and magnetic properties. This review discusses the research on the applications of functional materials, especially nanoparticles as imaging contrast agents, cancer therapeutic agents and multi-functional agents and this review focused on the theranostic integration treatments on liver cancer and brain cancer.

Incidence And Mortality

With increasing incidence and mortality rates, cancer remains one of the most devastating global non-communicable diseases. Restricted dosages and decreased bioavailability, often results in lower therapeutic outcomes, triggering the development of resistance to conventionally used drug/gene therapeutics. The development of novel therapeutic strategies using multimodal nanotechnology to enhance specificity, increase bioavailability and biostability of therapeutics with favorable outcomes is critical. Gated vectors that respond to endogenous or exogenous stimuli, and promote targeted tumor delivery without prematurely cargo loss are ideal. Mesoporous silica nanoparticles (MSNs) are effective delivery systems for a variety of therapeutic agents in cancer therapy. MSNs possess a rigid framework and large surface area that can incorporate supramolecular constructs and varying metal species that allow for stimuli-responsive controlled release functions. Its high interior loading capacity can incorporate combination drug/gene therapeutic agents, conferring increased bioavailability and biostability of the therapeutic cargo. Significant advances in the engineering of MSNs structural and physiochemical characteristics have since seen the development of nanodevices with promising in vivo potential. In this review, current trends of multimodal MSNs being developed and their use in stimuli-responsive passive and active targeting in cancer therapy will be discussed, focusing on light, redox, pH, and temperature stimuli.

Physical Instability

The epoch of nanotechnology has authorized novel investigation strategies in the area of drug delivery. Liposomes are attractive biomimetic nanocarriers characterized by their biocompatibility, high loading capacity, and their ability to reduce encapsulated drug toxicity. Nevertheless, various limitations including physical instability, lack of site specificity, and low targeting abilities have impeded the use of solo liposomes. Metal nanocarriers are emerging moieties that can enhance the therapeutic activity of many drugs with improved release and targeted potential, yet numerous barriers, such as colloidal instability, cellular toxicity, and poor cellular uptake, restrain their applicability in vivo. The empire of nanohybrid systems has shelled to overcome these curbs and to combine the criteria of liposomes and metal nanocarriers for successful theranostic delivery. Metallic moieties can be embedded or functionalized on the liposomal systems. The current review sheds light on different liposomal-metal nanohybrid systems that were designed as cellular bearers for therapeutic agents, delivering them to their targeted terminus to combat one of the most widely recognized diseases, cancer.

Heat shock protein 27 (HSP27), induced by heat shock, environmental, and pathophysiological stressors, is a multi-dimensional protein that acts as a protein chaperone and an antioxidant. HSP27 plays a major role in the inhibition of apoptosis and actin cytoskeletal remodeling. HSP27 is upregulated in many cancers and is associated with poor prognosis, as well as treatment resistance whereby cells are protected from therapeutic agents that normally induce apoptosis. This review highlights the most recent findings and role of HSP27 in cancer, as well as strategies for using HSP27 inhibitors for therapeutic purposes.

Abstract: Stimuli responsive nanocarriers are gaining much attention due to its versatile multifunctional activities including disease diagnosis and treatment. Recently, clinical applications of nano drug delivery systems for cancer treatment make a considerable challenge due to its limited cellular uptake, low bioavailability, poor targetability, stability issues, and unfavourable pharmacokinetics. To overcome these issues researchers are focussing on stimuli responsive systems. Nano carriers elicit its role through endogenous (pH, temperature, enzyme and redox) or exogenous (temperature, light, magnetic field, ultrasound) stimulus. These systems were designed to overcome the shortcomings such as non-specificity and toxicity associated with the conventional drug delivery systems. The pH variation between healthy cells and tumor microenvironment creates a platform towards the generation of pH sensitive nano delivery systems. Herein, we propose to present an overview of various internal and external stimuli responsive behavior based drug delivery systems. Herein the present review will focus specifically on the significance of various pH- responsive nanomaterials such as polymeric nanoparticles, nano micelles, inorganic based pH sensitive drug delivery carriers such as calcium phosphate nanoparticles, and carbon dots in cancer treatment. Moreover, this review elaborates the recent findings on pH based stimuli responsive drug delivery system with special emphasis towards our reported stimuli responsive systems for cancer treatment.

Future Direction

: Breast cancer remains one of the most common cancers in women worldwide, and despite significant improvements in treatment modalities, the prognosis of this cancer is still poor. Herbs and plant extracts have been associated with various health benefits, and traditional folk medicine is still receiving great interest among patients as proven by accumulated records, tolerable side effects of herbal compounds compared to their synthetic counterparts, and low cost. Curcumin is a polyphenol identified as the main active ingredient in turmeric and has been used in the treatment of various diseases and ailments. Additionally, the pharmacological activities of curcumin on many cancers have been investigated substantially due to its ability to regulate many signaling pathways involved in cancer tumorigenesis and metastasis. However, the low solubility and bioavailability of curcumin limit its benefits, urging the need for new curcumin formulations and delivery systems. Nanotechnology has been widely publicized in cancer treatment not only to overcome the limitations of poorly soluble and physiologically unstable compounds but also to improve the delivery of the drug to the diseased site and cellular uptake. In this review, we summarized the main anti-tumor effect of curcumin and its mode of action on breast cancer and focused on the anticancer efficacy of various and recent curcumin nanoformulations and delivery systems. Such nanotechnological systems could pave the way to address a new future direction in this research area, enhancing the therapeutic potential of curcumin in the treatment of breast cancer. In the next few years, there will be more focus on developing curcumin-based materials for breast cancer treatment.
