    Abstract Background: Age-related macular degeneration (AMD) is the leading cause of vision loss worldwide. However, the mechanisms involved in the development and progression of AMD are poorly delineated. We aimed to explore the critical genes involved in the progression of AMD.
    Methods: The differentially expressed genes (DEGs) in AMD retinal pigment epithelial (RPE)/choroid tissues were identified using the microarray datasets GSE99248 and GSE125564, which were downloaded from the gene expression omnibus database. The overlapping DEGs from the two datasets were screened to identify DEG-related biological pathways using gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. The hub genes were identified from these DEGs through protein-protein interaction network analyses. The expression levels of hub genes were evaluated by quantitative real-time polymerase chain reaction following the induction of senescence in ARPE-19 with FK866. Following the identification of AMD-related key genes, the potential small molecule compounds targeting the key genes were predicted by PharmacoDB. Finally, a microRNA-gene interaction network was constructed.
    Results: Microarray analyses identified 174 DEGs in the AMD RPE compared to the healthy RPE samples. These DEGs were primarily enriched in the pathways involved in the regulation of DNA replication, cell cycle, and proteasome-mediated protein polyubiquitination. Among the top ten hub genes, HSP90AA1, CHEK1, PSMA4, PSMD4, and PSMD8 were upregulated in the senescent ARPE-19 cells. Additionally, the drugs targeting HSP90AA1, CHEK1, and PSMA4 were identified. We hypothesize that Hsa-miR-16-5p might target four out of the five key DEGs in the AMD RPE.
    Conclusions: Based on our findings, HSP90AA1 is likely to be a central gene controlling the DNA replication and proteasome-mediated polyubiquitination during the RPE senescence observed in the progression of AMD. Targeting HSP90AA1, CHEK1, PSMA4, PSMD4, and/or PSMD8 genes through specific miRNAs or small molecules might potentially alleviate the progression of AMD through attenuating RPE senescence.

    Abstract Background: Artemisinin (ART) and its derivatives are important antimalaria agents and have received increased attention due to their broad biomedical effects, such as anticancer and anti-inflammation activities. Recently, ruthenium-derived complexes have attracted considerable attention as their anticancer potentials were observed in preclinical and clinical studies.
    Methods: To explore an innovative approach in colorectal cancer (CRC) management, we synthesized ruthenium-dihydroartemisinin complex (D-Ru), a novel metal-based artemisinin derivative molecule, and investigated its anticancer, anti-inflammation, and adaptive immune regulatory properties.
    Results: Compared with its parent compound, ART, D-Ru showed stronger antiproliferative effects on the human CRC cell lines HCT-116 and HT-29. The cancer cell inhibition of D-Ru comprised G1 cell cycle arrest via the downregulation of cyclin A and the induction of apoptosis. ART and D-Ru downregulated the expressions of pro-inflammatory cytokines IL-1β, IL-6, and IL-8. Although ART and D-Ru did not suppress Treg cell differentiation, they significantly inhibited Th1 and Th17 cell differentiation.
    Conclusions: Our results demonstrated that D-Ru, a novel ruthenium complexation of ART, remarkably enhanced its parent compound's anticancer action, while the anti-inflammatory potential was not compromised. The molecular mechanisms of action of D-Ru include inhibition of cancer cell growth via cell cycle arrest, induction of apoptosis, and anti-inflammation via regulation of adaptive immunity.

    Abstract Purpose: The aim of the present study was to develop an optimized Genkwanin (GKA)-loaded self-nanoemulsifying drug delivery system (SNEDDS) formulation to enhance the solubility, intestinal permeability, oral bioavailability and anti-colitis-associated colorectal cancer (CAC) activity of GKA.
    Methods: We designed a SNEDDS comprised oil phase, surfactants and co-surfactants for oral administration of GKA, the best of which were selected by investigating the saturation solubility, constructing pseudo-ternary phase diagrams, followed by optimizing thermodynamic stability, emulsification efficacy, self-nanoemulsification time, droplet size, transmission electron microscopy (TEM), drug release and intestinal permeability. In addition, the physicochemical properties and pharmacokinetics of GKA-SNEDDS were characterized, and its anti-colitis-associated colorectal cancer (CAC) activity and potential mechanisms were evaluated in AOM/DSS-induced C57BL/6J mice model.
    Results: The optimized nanoemulsion formula (OF) consists of Maisine CC, Labrasol ALF and Transcutol HP in a weight ratio of 20:60:20 (w/w/w), in which ratio the OF shows multiple improvements, specifically small mean droplet size, excellent stability, fast release properties as well as enhanced solubility and permeability. Pharmacokinetic studies demonstrated that compared with GKA suspension, the relative bioavailability of GKA-SNEDDS was increased by 353.28%. Moreover, GKA-SNEDDS not only significantly prevents weight loss and improves disease activity index (DAI) but also reduces the histological scores of inflammatory cytokine levels as well as inhibiting the formation of colon tumors via inducing tumor cell apoptosis in the AOM/DSS-induced CAC mice model.
    Conclusion: Our results show that the developed GKA-SNEDDS exhibited enhanced oral bioavailability and excellent anti-CAC efficacy. In summary, GKA-SNEDDS, using lipid nanoparticles as the drug delivery carrier, can be applied as a potential drug delivery system for improving the clinical application of GKA.

    Abstract Coronary heart disease (CHD) usually refers to myocardial ischemia or myocardial necrosis caused by coronary artery stenosis. GeGen and DanShen (GD) are popular Chinese herbs for the treatment of angina pectoris and myocardial infarction (MI). This sentence needs to be a separate paragraph.Aim of the study: This study was to investigate the role of GD extract in promoting ischemic myocardial angiogenesis, and to explore its signaling mechanism, so as to provide a more reliable scientific basis for the clinical treatment of ischemic cardiovascular disease.GD extract was initially analyzed by HPLC-Q-TOF MS. In vitro, migration assay and tube formation assay were subsequently used to detect the angiogenesis activity of GD extract in human umbilical vein endothelial cells (HUVECs). Following the in vitro study, an MI rat model was established by ligating the left anterior descending coronary artery (LAD), immediately followed by a 4-week daily GD extract treatment by intragastric administration. After the animal sacrifice, hematoxylin-eosin (HE) staining was conducted to observe the pathological changes of the infarct margin. Besides, the MI area was measured by 2,3,5-triphenyltetrazoliumchloride (TTC) staining. The microvascular density (MVD) was also quantified through CD31 immunohistochemistry. Moreover, the levels of VEGF, TXB2 and 6-keto-PGF1α in serum were detected by enzyme-linked immunosorbent assay. The expression of VEGFR2 and ERK were detected by immunohistochemistry as well.In vitro study, GD extract was found to induce significant angiogenesis in HUVECs. In vivo, smaller infarct size was found in treatment groups than that of the model group, and the protein expression of VEGFR2 as well as ERK in the marginal zone of MI in treatment groups were significantly increased. The morphological changes of myocardium were observed with a significant growth in the number of new blood vessels. Regarding the effect of GD extract, the serum levels of CK, LDH and TXB2 were consequently reduced, whereas the levels of VEGF, 6-keto-PGF1α were significantly increased.Based on the findings of this study, GD extract had a protective effect against MI in rats. The possible mechanism is to promote angiogenesis by regulating the VEGF/VEGFR2 signaling pathway after MI occurrence.
