etween MTSS1-AS and Myc in acidic PC cells. In accordance with the experimental results, MTSS1-AS and MTSS1 were downregulated in PC and correlated with poor overall survival. Conclusions The results implicated that a reciprocal feedback loop between Myc and MTSS1-AS contributed to the extracellular acidity-promoted metastasis of PC, and indicated that MTSS1-AS was a valuable biomarker and therapeutic target for PC.Ulcerative colitis (UC) is featured with relapsing inflammation in the colon, where macrophages are recruited and polarized locally into M1 type to drive further inflammation. Pharmacotherapy of UC has exhibited limited efficacy, mostly due to the poor specificity. Methods A macrophage-biomimetic nanomedicine was developed for targeted treatment of UC, which was derived from reactive oxygen species (ROS)-sensitive β-cyclodextrin, loaded with rosiglitazone, and coated with macrophage membrane. The ability of the nanomedicine in regulating macrophage polarization was examined at cellular level, and the macrophage-tropism driven targeted delivery into the inflammatory colon was investigated by ex vivo bio-imaging distribution assay. Furthermore, the nanomedicine's therapeutic efficacy was systemically examined in dextran sulfate sodium (DSS)-induced colitis model in mice. Results The nanomedicine effectively polarized macrophages to M2 and protected epithelial cells from oxidative stress in vitro. In addition, mor inflammation regulations.Rheumatoid arthritis (RA), a common inflammatory disorder of the joints characterized by synovitis and pannus formation, often results in irreversible joint erosion and disability. Methotrexate (MTX) is the first-line drug against RA, but the therapeutic effects are sub-optimal due to its poor retention at the target sites and systemic side effects. Multifunctional nanoparticles are highly promising agents for minimally invasive, traceable and effective targeted therapy. Methods This study developed iRGD peptide-functionalized echogenic liposomes (iELPs) which encapsulates MTX and indocyanine green (ICG) fluorescent probe through the thin film-hydration method. Results The resulting iELPs showed high affinity for endothelial cells overexpressing αvβ3 integrin, favorable acoustic response and fluorescence tracking properties. Also, near-infrared (NIR) fluorescence imaging of iELPs and ultrasound-triggered drug release of MTX were proved in a mouse RA model, greatly improving the therapeutic efficacy and reducing MTX side effects. Histological assessment of the articular tissues further revealed significantly lower inflammatory cell infiltration and angiogenesis in the iELPs-treated and sonicated mice. Conclusion Our study provides a promising nanoplatform for integrating ultrasound-controlled drug release and NIR fluorescence imaging for RA treatment.Background Urinary bladder cancer (UBC) is one of the most common causes of morbidity and mortality worldwide characterized by a high risk of invasion and metastasis; however, the molecular classification biomarkers and underlying molecular mechanisms for UBC patient stratification on clinical outcome need to be investigated. Methods A systematic transcriptomic analysis of 185 glycogenes in the public UBC datasets with survival information and clinicopathological parameters were performed using unsupervised hierarchical clustering. The gene signature for glycogene-type classification was identified using Limma package in R language, and correlated to 8 known molecular features by Gene Set Variation Analysis (GSVA). The clinical relevance and function of a glycogene was characterized by immunohistochemistry in UBC patient samples, and quantitative RT-PCR, Western blotting, promoter activity, MAL II blotting, immunofluorescence staining, wound healing, and transwell assays in UBC cells. Results A 14-glycogene sBCs.In recent decade, palladium-based (Pd-based) nanomaterials have shown significant potential for biomedical applications because of their unique optical properties, excellent biocompatibility and high stability in physiological environment. Compared with other intensively studied noble nanomaterials, such as gold (Au) and silver (Ag) nanomaterials, research on Pd-based nanomaterials started late, but the distinctive features, such as high photothermal conversion efficiency and high photothermal stability, have made them getting great attention in the field of nanomedicine. The goal of this review is to provide a comprehensive and critical perspective on the recent progress of Pd-based nanomaterials as imaging contrast agents and therapeutic agents. The imaging section focuses on applications in photoacoustic (PA) imaging, single-photon emission computed tomography (SPECT) imaging, computed tomography (CT) imaging and magnetic resonance (MR) imaging. For treatment of cancer, single photothermal therapy (PTT) and PTT combined with other therapeutic modalities will be discussed. Finally, the safety concerns, forthcoming challenges and perspective of Pd-based nanomaterials on biomedical applications will be presented.Rationale Tuberculosis (TB) remains the leading cause of death among infectious diseases worldwide. Poor compliance of TB patients to the lengthy treatment increases the risk of relapse and leads to the emergence of multidrug-resistant and extensively drug-resistant TB (MDR-TB and XDR-TB). More effective therapies for TB are urgently needed. We hypothesized that granulysin-mediated clearance of M. tuberculosis parasited inside and outside of alveolar macrophages in presumptive infected hosts might enhance the chemotherapeutic efficacy on TB. Methods Recombinant adenovirus type 5 (rAd5) based therapeutic vaccines rAdhGLi and rAdhGLs (rAds) were respectively developed to express intracellular and extracellular granulysin. The ex vivo bactericidal effects of rAdhGLi and rAdhGLs were evaluated on U937 and RAW264.7 cells. The efficacy of immunotherapy with both rAdhGLi and rAdhGLs on TB SCID mice, or immunotherapy combined with chemotherapy on drug-susceptible TB or MDR-TB mouse models were further evaluated. Results rAdhGLs, as well as rAdhGLi, showed a direct bactericidal effect on extracellular or intracellular M. tuberculosis H37Rv and MDR-TB clinical strains, respectively. Immunotherapy with a dose of 109 PFU of rAdhGLi and 109 PFU of rAdhGLs demonstrated a more significant bactericidal effect on M. tuberculosis H37Rv infected SCID mice and prolonged their survival periods than rAdhGLi or rAdhGLs alone. More importantly, chemotherapy combined with rAds immunotherapy shortened the chemotherapeutic duration to 4 months on M. tuberculosis H37Rv infected mice and prevented the relapse. Combination of rAds with chemotherapy on MDR-TB mice also more significantly decreased organ bacterial load than their single use. Nicotinamide Riboside supplier Conclusions Delivery of granulysin by recombinant adenovirus to the infected lung could enhance the clearance of TB in vivo and might be a promising adjunct therapeutic vaccine for TB and MDR-TB.
