Roscoe</em> is a traditional Chinese herb that has been used for thousands of years in China to treat various types of cancer. Curcumol is one of its primary bioactive sesquiterpenes and has been reported to possess antitumor properties; however, the underlying mechanisms in hepatocellular carcinoma (HCC) are largely unknown. The aim of this study was to reveal the mechanism of curcumol treating HCC based on the network pharmacology and experimental verification.</div></div><div><h3>Materials and Methods</h3><div>Targets of HCC and curcumol were identified. The drugs and disease targets were intersected by <em>Venn Diagram.</em> The KEGG pathway enrichment analysis of curcumol treating HCC was analyzed through the R 3.6.1 software. The effects of curcumol on the inhibition of HCC cell line HepG2 growth and its pro-apoptotic activity were evaluated by cell counting kit-8 and flow cytometry. The expression of microRNA-124 (miRNA-124) mRNA was detected by quantitative real-time PCR. HepG2 cells were transfected with a miRNA mimic and inhibitor. The expression of STAT3 and its phosphorylation were induced by IL-6 and detected by western blotting.</div></div><div><h3>Results</h3><div>MicroRNAs in cancer is a significant enrichment signaling pathway for curcumol treating HCC, according to the KEGG pathway analysis. Curcumol effectively inhibited HepG2 cell growth at 50–150 μg/ml, while it had low toxicity to normal LO2 cells. Using flow cytometry, curcumol strongly promoted apoptosis in HepG2 cells and was more potent than the miRNA-124 mimic, whereas the miRNA-124 inhibitor reduced the pro-apoptotic effect of curcumol. Western blotting revealed that curcumol significantly downregulated the overexpression of STAT3 and its phosphorylation in interleukin-6 induced HepG2 cells, whereas an increased level of STAT3 was observed in the miRNA-124 inhibitor transfected cells after curcumol treatment compared to untransfected cells. The level of miRNA-124 was changed up to 5.87-fold by curcumol treatment.</div></div><div><h3>Conclusions</h3><div>The mechanism underlying the effect of curcumol on inhibition and pro-apoptosis of HepG2 cell growth is possibly related to the miRNA-124/STAT3 pathway.</div></div>","PeriodicalId":52676,"journal":{"name":"Current Research in Biotechnology","volume":"9 ","pages":"Article 100270"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143136614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, adsorption of the proteins on cellulose nanofibrils (CNF) and the impact of the expansin-like proteins on the hydrolysis of CNF by an endoglucanase (Cel7B) was investigated using quartz crystal microbalance with dissipation (QCM-D). <em>Ama</em>EXLX1 showed higher affinity towards cellulose compared to <em>Apu</em>EXLX1, which was correlated to missing key aromatic residues in the polysaccharide binding surface of <em>Apu</em>EXLX1.

The main parameters for comparison included the geographical location, unit production cost, and environmental impact categories. The results show that the economic and environmental performances are highly variable among the different feedstocks and their processing routes, also depicting evident tradeoffs. Carbon dioxide, sugar cane molasses and glycerol from waste streams are performing better on assessed indicators overall than other potential feedstocks.

A total of 382 032 posts were shared by 109 935 users across 200 countries. The analysis focused on revealing key themes, geographical distribution, sentiment analysis, and the most frequently mentioned supplements and drugs related to longevity. The results show a high level of engagement with the hashtag, primarily driven by users from the United States, followed by the United Kingdom and Canada. Sentiment analysis revealed predominantly positive attitudes towards longevity-related topics, with a slight but statistically significant (p &lt; 0.0001) decline during and after the COVID-19 pandemic. The study identified nicotinamide mononucleotide, rapamycin, and green tea as the most frequently mentioned supplements or drugs in longevity discussions. Notably, there was a significant increase in discussions about niacin derivatives, particularly nicotinamide mononucleotide, during and after the pandemic period.
