Theranostics of Cancer with Gene Recognition


Gene recognition has extensively been applied in   bioanalysis and bioimaging, whether in vitro or in vivo, as well as   biomedicine such as clinical diagnosis and disease therapy due to its   excellent specificity, which is of significance in the design of signal   switch or signal amplifier for highly sensitive biosensing and cell-specific bioimaging of different biomolecules, and the development of siRNA delivery systems and drug   vectors for controllable   intracellular siRNA or drug release and precise therapy of cancer.The rational functionalization of nanomaterials with target-specific   DNA moieties to recognize different receptors both on cell surface and in   cells has led to a large number of versatile theranostic nanosystems. Here I   report several theranostic nanosystems developed in my group based on the   specific gene recognition. Firstly, several signal switches were designed for   sensitive bioimaging and in situ detection of cancer-related biomolecules   [1-6]. By functionalizing nanoparticles with cell-targeting moity and conjugated gene probe, a target-cell-specific   delivery strategy for imaging and detection of intracellular miRNA was   developed [1]. By interval hybridization of modified hairpin DNA probe pairs,   a responsive “nano string light” was   proposed for highly efficient mRNA imaging in living cells [2]. A photo zipper locked DNA   nanomachine was also assembled for precise miRNA imaging in living cells [3].   Besides RNA, two switchable fluorescent probes were developed for in situ   “off-on” imaging of intracellular   telomerase by its catalysis toward synthesis of telomeric repeats [4,5], and a hierarchical coding   strategy was proposed for live cell imaging of protein-specific glycoform   [6]. Secondly, some siRNA delivery systems   were designed for gene therapy of cancer [7-10]. A DNA dual lock-and-key   strategy was designed for cell-subtype-specific siRNA delivery [7], two   upconversion nanoprobes were developed for near-infrared modulated efficient   siRNA delivery and therapy [8,9], and in situ siRNA assembly was achieved in   living cells for gene therapy [10]. Thirdly, to enhance therapeutic   efficiency, a   DNA-azobenzene nanopump was designed for controllable intracellular drug   release [11], a near-infrared   photo-switched microRNA amplifier was proposed for precise photodynamic   therapy of early-stage cancers [12], and a DNA   nanomachine via computation across cancer cell membrane was recently developed   for precise therapy of solid tumor [13].
