Several chemokines and their receptors mediate tumor cell metastasis, particularly through long-term effects that regulate angiogenesis, tumor cell proliferation and apoptosis. Among them, CXC chemokine receptor 4 (CXCR4) has been shown to play a pivotal role in cancer metastasis through interaction with a ligand (CXCL12), also known as stromal cell-derived factor 1α (SDF-1α). The CXCR4 promoter region is well characterized, and its expression is controlled by various transcriptional factors, including NF-κB, HIF-1α, and so forth. Isoorientin (ISO) is a 3', 4', 5, 7-tetrahydroxy-6-C-glucopyranosyl flavone. ISO has been reported to exhibit anti-oxidant, anti-cancer, and anti-inflammatory properties. However, the anti-metastatic effect of ISO following downregulation of CXCR4 is unknown, and the mechanism underlying the antitumor activity has yet to be elucidated. In our present study, we showed that ISO inhibited the expression of CXCR4 through NF-κB regulation in breast and colon cancer cells. We have also demonstrated that ISO inhibits CXCR4 expression in a variety of tumor cells. Furthermore, we found that CXCR4 expression is regulated through inhibition of the transcription process. Inhibition of CXCR4 expression also reduced the invasion of cancer cells by CXCL12. In conclusion, our results suggest that ISO is a novel inhibitor to regulate CXCR4 expression and the key molecule contributing to antitumor activity.</p>","PeriodicalId":8949,"journal":{"name":"Biomolecules & Therapeutics","volume":" ","pages":"759-766"},"PeriodicalIF":3.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11535293/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142380048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following 8 weeks of high-fat diet (HFD) feeding, mice received oral doses of 30, 60, or 120 mg/kg of <i>Atractylodes lancea</i>.

Treatment with 5 or 10 mg/kg atractylodin also resulted in anti-obesity, anti-steatosis, and glucose-lowering effects. Atractylodin treatment resulted in the downregulation of key lipogenic genes (<i>Srebf1</i>, <i>Fasn</i>, <i>Scd2</i>, and <i>Dgat2</i>) and the upregulation of genes regulated by peroxisome proliferator-activated receptor-α.

Viruses such as Herpes Simplex Virus (HSV), Epstein-Barr Virus (EBV), Cytomegalovirus (CMV), and Human Immunodeficiency Virus (HIV) are linked to depression through complex neurobiological mechanisms. These include immune system dysregulation, chronic inflammation, and neurotransmitter imbalances that affect brain function and mood regulation. Viral activation of the immune system leads to the release of pro-inflammatory cytokines, resulting in neuroinflammation and associated depressive symptoms. Furthermore, specific viruses can disrupt neurotransmitter systems, including serotonin, dopamine, and glutamate, all of which are essential for mood stabilization. The unique interactions of different viruses with these systems underscore the need for virus-specific therapeutic approaches. Current broad-spectrum treatments often overlook the precise neurobiological pathways involved in post-viral depression, reducing their efficacy. This review emphasizes the need to understand these virus-specific interactions to create tailored interventions that directly address the neurobiological effects induced by each type of virus. These interventions may include immunomodulatory treatments that target persistent inflammation, antiviral therapies to reduce the viral load, or neuroprotective strategies that restore neurotransmitter balance. Precision medicine offers promising avenues for the effective management of virus-induced depression, providing patient-specific approaches that address the specific biological mechanisms involved.

By analyzing transcriptomic data from long-lived mutants that involved mechanisms such as antioxidation, dietary restriction, and genetic background, we identified collagen as a common longevity-associated gene.

The knockdown of eIF2S2 increased SMAD4 expression in cervical cancer cells without changing SMAD4 mRNA expression, whereas transient eIF2S2 overexpression reduced SMAD4 expression.

Additionally, eIF2S2 overexpression was confirmed to weaken the expression and/or promoter activity of p15 and p27, which are SMAD4-regulated antiproliferative proteins, by reducing SMAD4 levels.
