It has a crucial role in regulating physiological conditions in the human body, including body temperature and the secretion of hormones. Numerous disorders, such as cancer and diabetes, have been linked to disruptions of the cellular circadian rhythm. Herein, we aimed to investigate the relationship between the circadian rhythm and unfolded protein response (UPR) signaling, which is one of the important physiological mechanisms in mammalian cells and has recently been associated with drug resistance, invasion and metastasis in cancer. \u0000Material and Method: Human embryonic kidney cell line HEK293 was provided from the American Type Culture Collection and propagated in DMEM containing 10% FBS and growth ingredients. For in vitro circadian synchronization, cells were exposed to 50% and then the oscillation pattern of gene and protein expression of UPR-related target genes was analyzed by agarose gel electrophoresis and immunoblotting, respectively. The oscillation pattern was commented on through curve-fitting analysis.\u0000Result and Discussion: Our findings demonstrated that UPR components, including IRE1α, XBP-1s, eIF2α, phospho(Ser51)-eIF2α, PERK, ATF4, GADD34 and ATF6, tightly exhibit oscillation patterns under a circadian rhythm on a 48-hour time scale like the PER1 gene that is a core component of the circadian rhythm. Moreover, endoplasmic reticulum (ER) stress genes, BiP/GRP78 and CHOP, were similar to UPR components under the circadian rhythm. Additionally, we found the activation of UPR signaling harmoniously modulated with the circadian rhythm. Present data indicated that the expression level of UPR components exhibited strict oscillation under the circadian rhythm. Our findings may guide experimental studies of new-generation UPR-targeted drugs to be developed to treat various pathologies in accordance with the circadian rhythm.","PeriodicalId":7891,"journal":{"name":"Ankara Universitesi Eczacilik Fakultesi Dergisi","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141797120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Histopathological changes in the liver, lungs and kidneys were also assessed.\u0000Result and Discussion: SIL significantly reduced the cellular release of TNF-α and IL-6, which have been implicated in the pathogenesis of Cd-induced tissue damage. When SIL was administered alone, it showed histopathological effects similar to the control group. However, it was found that co-administration of SIL with Cd prevented portal vein dilation and central vein enlargement in the liver, prevented necrosis in kidney tissue, but did not affect the lung. Although SIL has variable protective effects on tissues, our results are in support of the idea that the use of SIL in tissue damage management can be investigated for its efficacy in modulating oxidative stress-induced proinflammatory cytokine activation in vivo and ultimately help prevent Cd-induced tissue damage. Our study has shown that SIL can reduce Cd-induced acute toxicity in rats. SIL may be use as a protective agent against toxicity of heavy metals.","PeriodicalId":7891,"journal":{"name":"Ankara Universitesi Eczacilik Fakultesi Dergisi","volume":"2 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141797135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The elevated anticancer potential of 2MLT was substantiated by utilizing the AntiCP 2.0 server and the ENNAACT server, employing machine learning and artificial neural network algorithms. Additionally, hydrophobicity analysis aligns with characteristics associated with anticancer peptides. Notably, thermodynamic stability variations with temperature underscore the robust binding affinity of 2MLT to the 5XF0 receptor.

Liver cancer is an extremely heterogeneous malignant disease compared to other defined tumors. To explore the potential therapeutic value of bioactive metabolites in Verbena officinalis, this study aimed to filter secondary metabolites, conduct ADME-Tox assessments, perform drug similarity tests, and analyze with molecular dynamic simulations. The objective was to evaluate how potential drug candidates derived from Verbena officinalis behave in biological systems and assess their potential toxicity risks. \u0000Material and Method: Ligands selected from the ADME assay were utilized in in silico molecular docking studies against Glucose-6-phosphate dehydrogenase enzyme in the oxidative part of the pentose phosphate pathway, which is crucial for liver diseases. These studies were conducted using Autodock Vina embedded in Chimera 1.16. Molecular dynamics simulations were performed with the AMBER16.\u0000Result and Discussion: When the ADME test results were evaluated, 88 secondary metabolites were identified as ligands. Among all the ligands evaluated against Glucose-6-phosphate dehydrogenase enzyme, which is the key enzyme of the pentose phosphate pathway, quercetin flavonoid was determined to be the most active ligand with a docking score of -8.1 kcal/mol and binding energy of -118.51 kcal/mol. A molecular dynamics simulation performed for 300 nanoseconds confirmed that quercetin can remain stable in its microenvironment.

Therefore, toxicogenomic data mining was conducted focusing on sunitinib, sorafenib, pazopanib, axitinib, and their associations with cardiovascular diseases.\u0000Material and Method: Common genes between tyrosine kinase inhibitors and cardiovascular diseases were uncovered via comparative toxicogenomic databases. Additionally, protein-protein and gene-gene interactions were identified using STRING and GeneMANIA, respectively. Subsequently, hub proteins associated with tyrosine kinase inhibitor-induced cardiovascular diseases were determined through Metascape. Transcription factors and microRNAs related to this toxicity were identified using ChEA3 and MIENTURNET, respectively. Finally, gene ontology enrichment analysis and the most associated molecular pathways were identified using the DAVID database and Metascape, respectively.\u0000Result and Discussion: Toxicogenomic data mining revealed six genes common between tyrosine kinase inhibitors and cardiovascular diseases, with five of these genes (FLT1, FLT4, KDR, MAPK1, and MAPK3) identified as hub genes. Physical interaction was dominant among these hub genes (77.64%). Sunitinib, sorafenib, pazopanib, and axitinib generally downregulated the activities of these proteins. SOX17 and SOX18 were prominent among transcription factors, while hsa-miR-199a-3p was the most important microRNA associated with this toxicity. Moreover, the Ras signaling pathway was mostly associated with tyrosine kinase inhibitor-induced cardiovascular toxicities. These findings make a substantial contribution to understanding the processes underlying cardiovascular diseases induced by sunitinib, sorafenib, pazopanib, and axitinib.
