AIM: The aim of this paper was to review the role of CMKLR-1 receptor and the potential therapeutic target in the management of chemerin induced type 2 diabetes mellitus and cancer.
PATHOPHYSIOLOGY: Increased chemerin secretion activates an inflammatory response. The inflammatory response will increase the oxidative stress in adipose tissue and consequently results in an insulin-resistant state. The occurrence of inflammation, oxidative stress and insulin resistance leads to the progression of cancers.
CONCLUSION: Chemerin is one of the markers that may involve in development of both cancer and insulin resistance. Chemokine like receptor- 1 (CMKLR-1) receptor that regulates chemerin levels exhibits a potential therapeutic target for insulin resistance, type 2 diabetes and cancer treatment.
METHODS: Polymeric nanocarriers are among one of the effective delivery systems, which has given promising results in the treatment of breast cancers. Nanocarriers does exert their anticancer effect either through active or passive targeting mode.
RESULTS: The use of nanocarriers has been resolute about the adverse effects of chemotherapeutic drugs such as poor solubility and less penetrability in tumor cells.
CONCLUSION: The present review is focused on recent developments regarding polymeric nanocarriers, such as polymeric micelles, polymeric nanoparticles, dendrimers, liposomes, nanoshells, fullerenes, carbon nanotubes (CNT) and quantum dots, etc. for their recent advancements in breast cancer therapy.
METHODS: Application of nanotechnology in medicine have perceived a great evolution during past few decades. Nanoemulsion, submicron sized thermodynamically stable distribution of two immiscible liquids, has gained extensive importance as a nanocarrier to improve chemotherapies seeking to overcome the limitations of drug solubilization, improving systemic delivery of the chemotherapeutics to the site of action to achieve a promising inhibitory in tumor growth profile with reduced systemic toxicity.
RESULTS AND CONCLUSION: This review has focused on potential application of nanoemulsion in the translational research and its role in chemotherapy using oral, parenteral and transdermal route to enhance systemic availability of poorly soluble drug. In summary, nanoemulsion is a multifunctional nanocarrier capable of enhancing drug delivery potential of cytotoxic agents, thereby, can improve the outcomes of cancer treatment by increasing the life-span of the patient and quality of life, however, further clinical research and characterization of interactive reactions should need to be explored.
OBJECTIVE: The application of molecularly engineered biodegradable and biocompatible polymeric particles with tunable features such as surface area and chemistry, particulate size distribution and toxicity creates opportunities to develop smart aptamer-mediated delivery systems for controlled drug release.
RESULTS: This article discusses opportunities for particulate aptamer-drug formulations to advance current drug delivery modalities by navigating active ingredients through cellular and biomolecular traffic to target sites for sustained and controlled release at effective therapeutic dosages while minimizing systemic cytotoxic effects.
CONCLUSION: A proposal for a novel drug-polymer-aptamer-polymer (DPAP) design of aptamer-drug formulation with stage-wise delivery mechanism is presented to illustrate the potential efficacy of aptamer- polymer cargos for enhanced cell targeting and drug delivery.
OBJECTIVE: Quercetin-decorated liposomes of curcumin (QCunp) are perceived to be able to overcome these biopharmaceutical drawbacks.
METHODS: Curcumin liposomes with/without quercetin were prepared by lipid hydration technique. The liposomes were characterized for their particle size, zeta potential, surface morphology, drug loading and release characteristics. The toxicity of the liposomes were evaluated in-vitro and their invivo efficacy were tested against Dalton's ascites lymphoma in mice.
RESULTS: Liposomes designed showed particle size of 261.8 ± 2.1 nm with a negative zeta potential of -22.6±1.6 mV. Quercetin decorated liposomes were more effective in increasing the life span and body weight of lymphoma inflicted mice compared to those without quercetin. Similarly, the presence of quercetin also contributed to enhanced cytotoxicity of the liposomal formulation towards HT-29 cells and HCT-15 cells.
CONCLUSION: Newer liposomal design exhibited promising potential to emerge as alternative anticancer therapeutics.
