Background: Prostate cancer (PCa) refers to malignant tumors derived from prostate epithelial cells, whose morbidity and mortality rates have been increasing every year. Although new drugs for treating prostate cancer continue to emerge, the unclear mechanism underlying drug targets limits this therapy, thereby constraining identification of effective therapeutic targets. Although GDP dissociation inhibitor 2(GDI2) is highly expressed and closely associated with occurrence and development of many tumors, its role in prostate cancer remains unclear.

In particular, optical-resolution photoacoustic microscopy (OR-PAM) requires the coaxial alignment of optical illumination and acoustic-detection paths through complex beam combiners and a thick coupling medium. To overcome these hurdles, we developed a novel OR-PAM method on the basis of our recently reported transparent lithium niobate (LiNbO) ultrasound transducer (Dangi et al.

However, it is challenging to ensure stable sequestration and sustained release of loaded biomolecules in these hydrogels. As aptamers have high binding affinities and specificities against target biomolecules, we studied the capability of aptamers in functionalizing in situ injectable fibrin (Fn) hydrogels for in vivo delivery of two growth factors including vascular endothelial growth factor (VEGF) and platelet-derived growth factor-BB (PDGF-BB).

Drug-loaded injectable hydrogels have been proven to possess huge potential for applications in tissue engineering. However, increasing the drug loading capacity and regulating the release system to adapt to the microenvironment after myocardial infarction face a huge challenge. In this research, an ROS-sensitive injectable hydrogel strengthened by self-nanodrugs was constructed.

However, the applications of nonviral vectors are still suffering from the limits of low drug loading efficiency and/or low gene transfection efficiency. Herein, a novel carrier-free nanodrug-based virus-surface-mimicking gene delivery nanosystem is designed by condensing doxorubicin nanoparticles (DNPs) onto the surface of the PEI/DNA nanocomplex through electrostatic force, which would prolong the blood circulation time of PEI/DNA and confer high drug loading characteristics to the PEI/DNA nanosystem.

Here, a novel near-infrared (NIR) laser-induced blasting carrier-free nanodrug delivery system is designed and fabricated by coating doxorubicin (DOX) nanoparticles (DNPs) with a polydopamine film (PDA) that would prolong the blood circulation time of DNPs and avoid the preleakage of the DOX during blood circulation. Meanwhile, the NHHCO is introduced to trigger in situ "bomb-like" release of DOX for the production of carbon dioxide (CO) and ammonia (NH) gases driven by NIR irradiated photothermal effect of PDA.

In this report, an amphiphilic mitochondria-targeted chimeric peptide-based drug delivery system (DDS) was designed to overcome drug resistance. In vitro studies revealed that chimeric peptide could encapsulate doxorubicin (DOX) with high efficacy and target tumor mitochondria, realizing controlled release of DOX and in situ photodynamic therapy (PDT) in mitochondria. Importantly, reactive oxygen species (ROS) during PDT significantly disrupted mitochondria, leading to a dramatic decrease of intracellular adenosine 5'-triphophate (ATP).
