Combined and targeted therapy have been extensively employed to achieve more effective elimination of tumor tissues. In this study, biocompatible multifunctional lipid-coated calcium phosphate nanoparticles (LCP NPs) were designed and constructed as an efficient targeted delivery system for combined gene/photothermal therapy to inhibit growth of the triple negative breast tumor (MDA-MB-468) in vitro and in vivo. LCP NPs were functionalized with a bispecific antibody (BsAb) via non-covalent bond specific for methoxy group of PEG (mPEG) on the particle surface. This BsAb is also able to target epidermal growth factor receptor (EGFR) expressed on MDA-MB-468 cells. Such LCP-BsAb NPs loaded with Cell Death (CD)-siRNA and indocyanine green (ICG) were efficiently taken up by MDA-MB-468 cells, significantly inducing cell apoptosis and synergistically suppressing cell proliferation upon irradiation of 808 nm near-infrared laser. These targeted multifunctional LCP NPs more efficiently accumulated in the tumor tissue. The combined RNAi (CD-siRNA) and photothermal (ICG) therapy using the targeted LCP NPs nearly eliminated both small tumors (∼100 mm) and large tumors (∼500 mm) in the mouse model. Thus, the well-devised multifunctional LCP NPs are one of the most promising delivery systems for combined and targeted cancer therapy.

Carbonic acid calcium salt (CaCO3). An odorless, tasteless powder or crystal that occurs in nature. It is used therapeutically as a phosphate buffer in hemodialysis patients and as a calcium supplement.
A multifunctional calcium-calmodulin-dependent protein kinase subtype that occurs as an oligomeric protein comprised of twelve subunits. It differs from other enzyme subtypes in that it lacks a phosphorylatable activation domain that can respond to CALCIUM-CALMODULIN-DEPENDENT PROTEIN KINASE KINASE.
A class of drugs that act by selective inhibition of calcium influx through cell membranes or on the release and binding of calcium in intracellular pools. Since they are inducers of vascular and other smooth muscle relaxation, they are used in the drug therapy of hypertension and cerebrovascular spasms, as myocardial protective agents, and in the relaxation of uterine spasms.
A perilipin that localizes to LIPID DROPLETS; CYTOPLASM; ENDOSOMES; and PLASMA MEMBRANE, especially in MACROPHAGES. It functions as a transporter of free fatty acids to lipid droplets to promote their biogenesis and growth. It is also required for the transport of the MANNOSE-6-PHOSPHATE RECEPTOR from endosomes to the TRANS-GOLGI NETWORK. Its structure consists of four helix bundles that interact with the hydrophobic lipid droplet surface.
A multifunctional protein that is found primarily within membrane-bound organelles. In the ENDOPLASMIC RETICULUM it binds to specific N-linked oligosaccharides found on newly-synthesized proteins and functions as a MOLECULAR CHAPERONE that may play a role in PROTEIN FOLDING or retention and degradation of misfolded proteins. In addition calreticulin is a major storage form for CALCIUM and functions as a calcium-signaling molecule that can regulate intracellular calcium HOMEOSTASIS.
