Abstract
BACKGROUND Cholangiocarcinoma (CCA) has a poor prognosis and only limited palliative treatment options. The deficiency of adiponectin and adenosine monophosphate-activated protein kinase (AMPK) signaling was reported in several malignancies, but the alteration of these proteins in CCA is still unclear. OBJECTIVES This study aimed to assess the role of adiponectin and AMPK signaling in CCA. Furthermore, AdipoRon, a novel adiponectin receptor (AdipoR) agonist, was evaluated in vitro and in vivo as a new anti-tumor therapy for CCA. METHODS The expression of AdipoR1 and p-AMPKα in human tissue microarrays (TMAs) was evaluated by immunohistochemistry staining (IHC). The effect of 2-(4-Benzoylphenoxy)-N-[1-(phenylmethyl)- 4-piperidinyl]-acetamide (AdipoRon) was investigated in vitro with proliferation, crystal violet, migration, invasion, colony formation, senescence, cell cycle and apoptosis assays and in vivo using a CCA engineered mouse model (AlbCre/LSL-KRASG12D/p53L/L). RT-qPCR and western blot methods were applied to study molecular alterations in murine tissues. RESULTS AdipoR1 and p-AMPKα were impaired in human CCA tissues, compared to adjacent non-tumor tissue. There was a positive correlation between the AdipoR1 and p-AMPKα levels in CCA tissues. Treatment with AdipoRon inhibited proliferation, migration, invasion and colony formation and induced apoptosis in a time- and dose-dependent manner in vitro(p<0.05). In addition, AdipoRon reduced the number of CCA and tumor volume, prolonged survival, and decreased metastasis and ascites in the treated group compared to the control group (p<0.05). CONCLUSIONS AdipoR1 and p-AMPKα are impaired in CCA tissues, and AdipoRon effectively inhibits CCA in vitro and in vivo. Thus, AdipoRon may be considered as a potential anti-tumor therapy in CCA.

Abstract
Adiponectin, an adipokine secreted by adipocytes, has anti-atherosclerotic and antithrombotic activities. AdipoRon is synthetic small molecule adiponectin receptor agonist. In this study, we investigated the effect of AdipoRon on platelet activation and thrombus formation. Washed human platelets were prepared from the peripheral blood of healthy donors. In a series of in vitro platelet functional assays, pre-treatment with AdipoRon (10, 20, 40 µg/mL) dose-dependently inhibited the aggregation, granule secretion and spreading of washed human platelets. We showed that AdipoRon (20, 40 µg/mL) significantly inhibited AMPK, Syk, PLCγ2, PI3K, Akt, p38-MAPK and ERK1/2 signalling pathways in washed human platelets. In addition, we demonstrated that the phosphorylation of CKII at Tyr255 was an important mechanism of the integrin αIIbβ3-mediated platelet activation. Meanwhile, AdipoR1 deficiency impaired the inhibitory effect of AdipoRon on mouse platelets. In ferric chloride-induced carotid injury model, injection of AdipoRon (5 or 12.5 mg/kg, iv) significantly attenuated arterial thrombosis. In conclusion, AdipoRon attenuates platelet function via the AdipoR1/AMPK/CKII/PI3K/AKT signalling pathways, while exerting a protective effect against arterial thrombosis. This study offers new insights into the fields of cardiovascular disease and antiplatelet drug discovery.Schematic model of AdipoRon regulating platelet activation. (BioRender.com).

Abstract
Abnormal vascular smooth muscle cell (SMC) dedifferentiation with increased proliferation and migration during pathological vascular remodeling is associated with vascular disorders, such as atherosclerosis and in-stent restenosis. AdipoRon, a selective agonist of adiponectin receptor, has been shown to protect against vascular remodeling by preventing SMC dedifferentiation. However, the molecular mechanisms that mediate adipoRon-induced SMC differentiation are not well understood. The present study aimed to elucidate the role of transcription factor EB (TFEB), a master regulator of autophagy, in mediating adipoRon's effect on SMCs. In cultured arterial SMCs, adipoRon dose-dependently increased TFEB activation, which is accompanied by upregulated transcription of genes involved in autophagy pathway and enhanced autophagic flux. In parallel, adipoRon suppressed serum-induced cell proliferation and caused cell cycle arrest. Moreover, adipoRon inhibited SMC migration as characterized by wound-healing retardation, F-actin reorganization, and matrix metalloproteinase-9 downregulation. These inhibitory effects of adipoRon on proliferation and migration were attenuated by TFEB gene silencing. Mechanistically, activation of TFEB by adipoRon is dependent on intracellular calcium, but it is not associated with changes in AMPK, ERK1/2, Akt, or molecular target of rapamycin complex 1 activation. Using ex vivo aortic explants, we demonstrated that adipoRon inhibited sprouts that had outgrown from aortic rings, whereas lentiviral TFEB shRNA transduction significantly reversed this effect of adipoRon on aortic rings. Taken together, our results indicate that adipoRon activates TFEB signaling that helps maintain the quiescent and differentiated status of arterial SMCs, preventing abnormal SMC dedifferentiation. This study provides novel mechanistic insights into understanding the therapeutic effects of adipoRon on TFEB signaling and pathological vascular remodeling.

Abstract
Neuroinflammation is considered to be a critical component in the pathological process after intracerebral hemorrhage (ICH). Microglia are the foremost and earliest inflammatory cells participating in the pathological process of ICH. AdipoRon is the agonist of AdipoR1 (Adiponectin receptor 1), which enhances P-AMPK (phosphorylated AMP-activated protein kinase) activation. The activated AMPK facilitates microglia/macrophage polarization by driving the cell state from pro-inflammatory M1 state to anti-inflammatory M2 state. The study aims to investigate the role of AdipoRon in microglial polarization and neuroprotection after ICH. The experimental ICH model was established by autologous blood injection, and the treated group was done additionally by intraperitoneal injection of drugs. Flow cytometry analysis and immunofluorescence staining were performed to quantify the ratio of M1 to M2 phenotype microglia in mice. The present study indicated that AdipoRon could ameliorate neurological deficits in mice after ICH. Flow cytometric analysis demonstrated that the proportion of CD206+ cells to CD45+low CD11b+ cells (microglia isolated from the brain tissue of mice) was increased after AdipoRon treatment. AdipoR1 siRNA and AMPK inhibitor could reverse the positive effects of AdipoRon. AdipoR1 and P-AMPK expression was also significantly increased after AdipoRon treatment. The in vitro experiment showed that AdipoRon not only directly inhibited neuronal ROS overproduction, but also indirectly decreased the neuronal death in a transwell co-culture system. In summary, AdipoRon protects against ICH induced injury through promoting M2a microglia polarization and reducing neuronal death. These effects of AdipoRon rely on the activation of AdipoR1-AMPK signaling pathway.
