Helicobacter pylori causes a Gram-negative bacterial infection that can increase the risk of gastric cancer. Consequently, meticulous prevention of an H. pylori infection is significant for averting gastric cancer in humans. Nobiletin, an important dietary polymethoxylated flavonoid in citrus fruits, possesses multidimensional pharmaceutical properties, including its ability to act as an anticancer, anti-inflammatory, antioxidative, cardiovascularly defensive, neuroprotective, and antimetabolic agent. this website Our study evaluates the role of nobiletin in inflammation-mediated gastric carcinogenic signaling of H. pylori-arbitrated coculture in the human gastric epithelial (GES)-1 cell line. Our results show that the culture system of H. pylori-tainted GES-1 cells demonstrates maximum fabrication of reactive oxygen species (ROS), mediating DNA injury and augmenting nuclear fragmentations. Treatment with nobiletin reduces ROS levels and apoptotic morphological changes by dual staining and decreases levels of lipid peroxides and glutathione content in H. pylori-infected GES-1 cells. Phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT)/phosphatase and tensin homolog signaling have been implicated to affect cell endurance, inflammation, proliferation, and carcinogenic activity in gastric GES-1 cells. We find that nobiletin strongly impedes tumor necrosis factor-α, interleukin-6, cyclooxygenase-2, PI3K, AKT, and mitogen-activated protein kinase molecules, including p38, extracellular receptor kinase 1, and c-Jun amino-terminal expression in H. pylori-infected GES-1 cells. We conclude that nobiletin potentially impedes H. pylori infection and its related activation, likely preventing H. pylori infection-mediated gastric cancer.Atherosclerosis is a multifactorial disease that develops and progresses in the arterial wall in response to a variety of stimuli. Among various other stimuli, hyperlipidemia is an extremely important factor that is correlated with the development of atherosclerosis. Lemon and citrus fruits contain various bioactive flavonoids, such as eriocitrin, that prevent obesity and related metabolic diseases. Therefore we concentrated on eriocitrin, a potent flavonoid with numerous therapeutic properties, particularly its beneficial lipid-lowering action in rats subjected to high fat diet. The anti-atherosclerotic efficacy of eriocitrin was assessed in rats administered a diet rich in fat. Wistar rats were divided into five groups consisting of six animals in all groups. Group I served the control, Group II was fed a high-fat diet (HFD), and the third and fourth groups were fed an HFD supplemented with varying doses of eriocitrin, and the last group was administered simvastatin for the last 30 days. Body weight, organ weight, lipid and lipoprotein parameters, cardiac and inflammatory markers, and histological examination were evaluated in animals induced with an HFD. Eriocitrin displayed a significant anti-atherosclerotic action by lowering the body weight, organ weight, reduction in lipid content, cardiac and inflammatory markers, myocardial changes confirmed by histopathology, malondialdehyde and increased antioxidant enzyme activities, nitric oxide, as well as 6-keto-PGF1α and high-density lipoprotein levels in rats fed an HFD. The findings of the experiment suggest that the anti-atherosclerotic action of eriocitrin was due to its modulatory activity in lipid metabolism. Considering the overall results of the study it can be validated that a use of flavonoid eriocitrin might be beneficial in altering HFD-induced alterations in atherosclerotic rats.The aim of the present study was to explore the anti-breast cancer activity of the plant I. turpethum together with the comparative analysis of the cytotoxicity of the extracts from different parts of the plant. The gas chromatography-mass spectrometry (GC-MS) analysis of the plant revealed the identification of 71 compounds. The cytotoxicity of the extracts from different parts (whole, aerial, and root) of the plant was evaluated against the breast cancer cell lines (MCF-7 and MDA MB-231) by 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase (LDH) assays. The findings of these assays were further confirmed by the carboxyfluorescein diacetate succinimidyl ester (CFSE) proliferation assay, DAPI (4',6-diamidino-2-phenylindole) nuclear staining, and simple microscopy images. The results of the MTT assay revealed that the root extract showed the lowest IC50 values, i.e., 516 μg/mL for MCF-7 and 396 μg/mL for MDA MB-231 cell lines. The LDH release in the medium was high in the root extract treated cells, i.e., 28.87% for MCF-7 and 23.62% for MDA MB-231 cell lines. Moreover, the CFSE proliferation assay also showed the decrease in the proliferation of the cells up to 48.7% and 46.4% in case of MCF-7 and MDA MB-231 cells, respectively. The fragmented and condensed nuclear material in both the cell lines was observed in the DAPI nuclear staining. In conclusion, results showed that the root extract possess the highest cytotoxicity among all other tested extracts toward both breast cancer cell lines (MCF-7 and MDA MB-231).Colon cancer (CC) is the most common type of gastrointestinal cancer and is the third leading cause of cancer patient's death worldwide. Long non-coding RNAs (lncRNAs) are important regulatory molecules involved in various cellular processes, and many of them are shown as significant prognosis biomarkers of malignant tumors. In the present study, we identified differentially expressed lncRNAs between CC and adjacent normal tissues based on two TCGA database (GEPIA and circlncRNAnet). Over 1500 differentially expressed lncRNAs between CC and adjacent normal tissues were obtained based on these two websites, and 72 lncRNAs (FC > = 2, Log2 (TPM+1) > 1, P less then 0.05) were chosen for further analysis. Seventeen of them were CC specific-expressed lncRNAs. We then evaluated the expression of the 17 lncRNAs in diverse tumor stage. LncRNA double homeobox A pseudogene 8 (DUXAP8), RP11-54H7.4, and RP11-138J23.1 showed higher expression in later tumor stages. Built on survival analysis, we found that high expression of DUXAP8 and ELFN1 antisense RNA 1 (ELFN1-AS1) predicts poor prognosis in CC.
