Abstract
N-Oxyamides of bioactive anionic glycoglycerolipids based on 2-O-β-D-glucosylglycerol were efficiently prepared. However, the oxidation step of the primary hydroxyl group of the glucose moiety in the presence of the N-oxyamide function appeared to be a difficult task that was nevertheless conveniently achieved for the first time by employing a chemoenzymatic laccase/TEMPO procedure. The obtained N-oxyamides exhibited a higher inhibition of proliferation of ovarian carcinoma IGROV-1 cells in serum-free medium than in complete medium, similarly to the corresponding bioactive esters. Stability and serum binding studies indicated that the observed reduced activity of the compounds in complete medium could be mainly due to a binding effect of serum proteins rather than the hydrolytic degradation of glycoglycerolipid acyl chains. Furthermore, the results of the cellular studies under serum-free conditions suggested that the N-oxyamide group could increase the antiproliferative activity of a glycoglycerolipid independently of the presence of the anionic carboxylic group. Cellular studies in other cell lines besides IGROV-1 also support a certain degree of selectivity of this series of compounds for tumor cells with Akt hyperactivation.

Abstract
Impaired wound healing is one of the severe complications of diabetes. Macrophages have been shown to play a vital role in wound healing. In different wound environments, macrophages are classified into two phenotypes: classically activated macrophages and alternatively activated macrophages. Dysregulation of macrophage phenotypes leads to severely impaired wound healing in diabetes. Particularly, uncontrolled inflammation and abnormal macrophage phenotype are important reasons hindering the closure of diabetic wounds. This article reviews the functions of macrophages at various stages of wound healing, the relationship between macrophage phenotypic dysregulation and diabetic wound healing and the mechanism of macrophage polarization in diabetic wound healing. New therapeutic drugs targeting phagocyte polarization to promote the healing of diabetic wounds might provide a new strategy for treating chronic diabetic wound healing.

Abstract
Recent studies have emphasized microRNAs (miRs) as crucial regulators in the occurrence and development of pancreatic cancer that continues to be one of the deadliest malignancies with few effective therapies. The study aimed to investigate the functional role of miR-873 and its associated mechanism to unravel the biological characteristics of pancreatic cancer stem cells in tumor growth. The expression patterns of pleckstrin-2 (PLEK2) and miR-873 were detected in the pancreatic cancer tissues. Then to further investigate specific role of miR-873, the pancreatic cancer stem cells were treated with miR-873 mimic, PLEK2, small interfering RNA against PLEK2, LY294002 (inhibitor of phosphatidylinositol 3-kinase/protein kinase B [PI3K/AKT] pathway) to detect the relative gene expression as well as their effects on cell self-renewal, proliferation and apoptosis. Finally, the tumor formation in nude mice was measured to verify the preceding results in vivo. Pancreatic cancer tissues exhibited a decline of miR-873 expression and an enhancement of PLEK2 expression. miR-873 targeted PLEK2 and downregulated its expression, leading to inhibition of PI3K/AKT pathway. Overexpressed miR-873 or silenced PLEK2 inhibited the self-renewal and proliferation while promoting the apoptosis of pancreatic cancer stem cells. Tumor formation was inhibited by overexpressed miR-873 or silenced PLEK2 in nude mice. Overall, miR-873 can suppress the self-renewal and proliferation of pancreatic cancer stem cells by blocking PLEK2-dependent PI3K/AKT pathway. Hence, this study contributes to understanding the role of miR-873 in pancreatic cancer stem cells and its underlying molecular mechanisms to aid in the development of effective pancreatic cancer therapeutics.

Geniposide alleviates hypoxia-induced injury by down-regulation of lncRNA THRIL in rat cardiomyocytes derived H9c2 cells. Eur J Pharmacol 2019; 854:28-38. [PMID: 30953616 DOI: 10.1016/j.ejphar.2019.03.058] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2018] [Revised: 03/20/2019] [Accepted: 03/28/2019] [Indexed: 12/24/2022]
Abstract
Geniposide (GEN) is an iridoid glycoside extracts from Gardenia jasminoides Ellis with antioxidant and anti-inflammarory properties. The objective of this study was to explore the effects of GEN on a cell model of myocardial infarction (MI). After transfection, hypoxia-stimulated H9c2 cells were treated with GEN. Cell viability and apoptosis were detected by Cell Counting kit-8 assay and flow cytometry, respectively. Cell cycle-, apoptosis- and signal pathway related proteins were examined by Western blot. The expression of THRIL was determined by qRT-PCR. In addition, in vivo experiments were performed in rats. Then the infarct size and the left ventricular (LV) end diastolic diameter (LVEDD), LV ejection fraction (LVEF) and LV fractional shortening (LVFS) were monitored. Results showed that treating H9c2 cells with GEN attenuated hypoxia-induced cell damage as cell viability was increased, and cell apoptosis was repressed. Meanwhile, THRIL was found to be down-regulated by GEN. The cardioprotective effects of GEN on H9c2 cells were attenuated when THRIL was overexpressed. Besides this, the phosphorylation of PI3K, AKT, JAK1 and STAT3 were up-regulated by GEN while down-regulated by THRIL overexpression. Moreover, GEN decreased infarct size and LVEDD, while increased LVEF and LVFS. Taken together, this study demonstrated that GEN alleviated cardiomyocytes damage and cardiac dysfunction possible through down-regulation of THRIL.

Abstract
Proteins associated to the PI3K/AKT/mTOR signaling pathway are widely used targets for cancer treatment, and in recent years they have also been evaluated as putative targets in trypanosomatids parasites, such as Trypanosoma cruzi. Here, we performed a virtual screening approach to find candidates that can bind regions on or near the Pleckstrin homology domain of an AKT-like protein in T. cruzi. The compounds were also evaluated in vitro. The in silico and experimental results allowed us to identify a set of compounds that can potentially alter the intracellular signaling pathway through the AKT-like kinase of the parasite; among them, a derivative of the pyrazolopyridine nucleus with an IC50 of 14.25 ± 1.00 μM against amastigotes of T. cruzi. In addition, we built a protein–protein interaction network of T. cruzi to understand the role of the AKT-like protein in the parasite, and look for additional proteins that can be postulated as possible novel molecular targets for the rational design of compounds against T. cruzi.

[PMID: 29445190 PMCID: PMC5833857 DOI: 10.1038/s41419-018-0267-9] [Citation(s) in RCA: 38] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2017] [Revised: 11/27/2017] [Accepted: 11/28/2017] [Indexed: 02/08/2023]
Abstract
G-protein-coupled receptor (GPCR)-related proteins are dysregulated and the GPCR CC-chemokine receptor 10 (CCR10) is significantly upregulated in inflammation-driven HCC. However, CCR10′s role in inflammation-driven hepatocarcinogenesis remains unknown. The aim of this study was to evaluate the role of CCR10 in inflammation-driven hepatocarcinogenesis. Via a targeted gene expression microarray screening alterations in GPCR family gene expression, we found CCR10 to be significantly upregulated in hepatocytes isolated from inflammation-driven human HCC tumors and matching paracancerous tissues. Tetrachloromethane (CCl4)-induced and diethylnitrosamine (DEN)-induced murine models of inflammatory hepatocarcinogenesis displayed significant hepatocellular TNF and CCR10 upregulation. Exogenous TNF applied to HepG2 and LO2 cell lines as well as wild-type (WT) mice significantly upregulated hepatocellular CCR10 expression, Akt phosphorylation, PCNA expression, and hepatocellular proliferation. Additionally, exogenous TNF significantly upregulated secretion of the natural CCR10 ligand-agonist CCL28 from both cell lines. Transgenic CCR10-knockout (CCR10 KO) in DEN-treated mice significantly increased hepatocellular apoptosis levels and significantly lowered compensatory hepatocellular proliferation but did not affect upstream TNF expression. In addition, DEN-treated CCR10 KO mice showed a significantly lower liver weight/body weight ratio, significantly lower liver tumor incidence, and significantly smaller tumors. Moreover, exogenous CCR10 expression significantly raised xenograft tumor growth in Balb/c nude mice. In vitro, CCR10 transfection or CCL28 treatment in HepG2 and LO2 cell lines significantly increased Akt phosphorylation, PCNA expression, and cell proliferation, while CCR10 silencing or Akt inhibition produced the opposite effects. In vivo, hepatocytes isolated from HCC tumor tissue and matching paracancerous tissue in DEN-treated CCR10 KO mice showed significantly lower Akt phosphorylation and PCNA expression relative to WT hepatocytes. In conclusion, inflammation-induced TNF promotes hepatocellular CCR10 expression and downstream PI3K/Akt-mediated hepatocarcinogenesis. CCR10 appears to function as a linkage between TNF stimulation and downstream PI3K/Akt pathway activation and shows promise as a potential therapeutic target for inflammation-driven HCC.

Abstract
Amphiphilicity is one of the desirable features in the process of drug development which improves the biological as well as the pharmacokinetics profile of bioactive molecule. Carbohydrate moieties present in anti-cancer natural products and synthetic molecules influence the amphiphilicity and hence their bioactivity. This review focuses on natural and synthetic amphiphilic anti-cancer glycoconjugates. Different classes of molecules with varying degree of amphiphilicity are covered with discussions on their structure-activity relationship and mechanism of action.
