[PMID: 38806109 DOI: 10.1016/j.cellsig.2024.111235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 05/16/2024] [Accepted: 05/24/2024] [Indexed: 05/30/2024]
Abstract
In this study, we investigated the molecular mechanisms underlying the impact of extracellular vesicles (EVs) derived from bone marrow stromal cells (BMSCs) on colorectal cancer (CRC) development. The focus was on the role of MAGI2-AS3, delivered by BMSC-EVs, in regulating USP6NL DNA methylation-mediated MYC protein translation modification to promote CDK2 downregulation. Utilizing bioinformatics analysis, we identified significant enrichment of MAGI2-AS3 related to copper-induced cell death in CRC. In vitro experiments demonstrated the downregulation of MAGI2-AS3 in CRC cells, and BMSC-EVs were found to deliver MAGI2-AS3 to inhibit CRC cell proliferation, migration, and invasion. Further exploration revealed that MAGI2-AS3 suppressed MYC protein translation modification by regulating USP6NL DNA methylation, leading to CDK2 downregulation and prevention of colorectal cancer. Overexpression of MYC reversed the functional effects of BMSC-EVs-MAGI2-AS3. In vivo experiments validated the inhibitory impact of BMSC-EVs-MAGI2-AS3 on CRC tumorigenicity by promoting CDK2 downregulation through USP6NL DNA methylation-mediated MYC protein translation modification. Overall, BMSC-EVs-MAGI2-AS3 may serve as a potential intervention to prevent CRC occurrence by modulating key molecular pathways.

Shen L, Zhang C, Zhu G. Low-density lipoprotein receptor-related protein 5/6 promotes endometrial cancer progression and cancer cell immune escape. J Biochem Mol Toxicol 2024; 38:e23677. [PMID: 38528715 DOI: 10.1002/jbt.23677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 01/02/2024] [Accepted: 02/23/2024] [Indexed: 03/27/2024]
Abstract
The study investigated the potential association of the low-density lipoprotein (LDL) genome with endometrial cancer progression based on the Gene Expression Omnibus data set and The Cancer Genome Atlas data set. Differential and weighted gene coexpression network analysis was performed on endometrial cancer transcriptome datasets GSE9750 and GSE106191. The protein-protein interaction network was built using LDL-receptor proteins and the top 50 tumor-associated genes. Low-density lipoprotein-related receptors 5/6 (LRP5/6) in endometrial cancer tissues were correlated with oncogenes, cell cycle-related genes, and immunological checkpoints using Spearman correlation. MethPrimer predicted the LRP5/6 promoter CpG island. LRP2, LRP6, LRP8, LRP12, low-density lipoprotein receptor-related protein-associated protein, and LRP5 were major LDL-receptor-related genes associated with endometrial cancer. LRP5/6 was enriched in various cancer-related pathways and may be a key LDL-receptor-related gene in cancer progression. LRP5/6 may be involved in the proliferation process of endometrial cancer cells by promoting the expression of cell cycle-related genes. LRP5/6 may be involved in the proliferation of endometrial cancer cells by promoting the expression of cell cycle-related genes. LRP5/6 may promote the immune escape of cancer cells by promoting the expression of immune checkpoints, promoting endometrial cancer progression. The MethPrimer database predicted that the LRP5/6 promoter region contained many CpG islands, suggesting that DNA methylation can occur in the LRP5/6 promoter region. LRP5/6 may aggravate endometrial cancer by activating the phosphoinositide 3-kinase/protein kinase B pathway.

Traditional Chinese medicine Kuan-Sin-Yin decoction inhibits cell mobility via downregulation of CCL2, CEACAM1 and PIK3R3 in hepatocellular carcinoma cells. JOURNAL OF ETHNOPHARMACOLOGY 2023; 317:116834. [PMID: 37355084 DOI: 10.1016/j.jep.2023.116834] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/10/2023] [Accepted: 06/21/2023] [Indexed: 06/26/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kuan-Sin-Yin (KSY) is a traditional Chinese medical decoction, designed based on the classic Si-Jun-Zi-Tang decoction and used clinically to improve the synergic effects of energy promotion, liver function and cancer related symptom and quality of life. However, the anti-hepatocellular carcinoma (HCC) function of KSY is unclear. AIM OF THE STUDY This study aimed to investigate the anti-mobility activity of KSY on HCC cells and elucidate its molecular mechanism. MATERIALS AND METHODS Two malignancy hepatocellular carcinoma cells, Mahlavu and SK-Hep-1, were used for the test of cell proliferation via alarm blue assay. The wound healing and Transwell assays were used to determine the anti-mobility activity of KSY in HCC cells. Cell morphology was analyzed via confocal microscopy. The genomic profile of KSY-treated HCC cells was analyzed by microarray. The potential signaling pathways and bio-functions of KSY-mediated genes were analyzed by ingenuity pathway analysis (IPA). Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to detect the messenger RNA (mRNA) level of indicated gene. RESULTS KSY did not affect cell viability of HCC cells but significantly inhibited cell migration and invasion in those HCC Mahlavu and SK-Hep-1 cells. In parallel, KSY induced changes in morphology of HCC cells via re-modulating actin cytoskeleton. KSY upregulated 1270 genes but reduced 1534 genes in Mahlavu cells. KSY regulated various gene networks which controlled cell migration, invasion and movement. Specifically, KSY reduced expression of chemokine (C-C motif) ligand 2 (CCL2), which is correlated to cell mobility, and concomitantly downregulated mRNA levels of phosphoinositide-3-kinase regulatory subunit 3 (PIK3R3) and CEA cell adhesion molecule 1 (CEACAM1). CONCLUSION These findings indicated that regulation of CCL2-mediated PIK3R3 and CEACAM1 may be involved in KSY inhibited cell mobility. Moreover, KSY may be a potential a Chinese decoction for reducing cell mobility.

Abstract
Prior evidence has suggested the alleviatory effect of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) on neuroinflammation in neurodegenerative diseases. This study primarily investigates the underlying mechanism of how the long non-coding RNA MALAT1 affects neuronal apoptosis in the hippocampus of mice with autism spectrum disorder (ASD). The findings demonstrate that CASP3 is highly expressed while MALAT1 is downregulated in the hippocampal neurons of autistic mice. MALAT1 mainly localizes within the cell nucleus and recruits DNA methyltransferases (including DNMT1, DNMT3a, and DNMT3b) to the promoter region of CASP3, promoting its methylation and further inhibiting its expression. In vitro experiments reveal that reducing MALAT1 expression promotes the expression of CASP3 and Bax while suppressing Bcl-2 expression, thereby enhancing cellular apoptosis. Conversely, increasing MALAT1 expression yields the opposite effect. Consequently, these results further confirm the role of MALAT1 in suppressing neuronal apoptosis in the hippocampus of mice with ASD through the regulation of CASP3 promoter methylation. Thus, this research unveils the significant roles of MALAT1 and CASP3 in the pathogenesis of ASD, offering new possibilities for future therapeutic interventions.

Abstract
Background: To research the impact of a Chinese traditional medicine (Citrus aurantium L.) on gastric cancer proliferation and mice gastrointestinal motility. Materials and Methods: The intestinal transit rates (ITRs) and gastric emptying (GE) values in mice with experimentally induced gastrointestinal motility dysfunction (GMD) and in normal mice were calculated to research the in vivo influences of C. aurantium L. on gastrointestinal motility. CCK-8 was used to examined the effect of C. aurantium L. on gastric cancer proliferation. Results: The GE and ITR values were dose-dependently and notably added by C. aurantium L. in normal ICR mice (with 1 g/kg C. aurantium L., ITR values: 53.3% ± 0.8% versus 64.3% ± 0.9% and 53.3% ± 0.8% versus 79.8% ± 2.0%, p < 0.01; GE values: 59.3% ± 0.8% versus 70.1% ± 1.9% and 59.9% ± 0.8% versus 69.9% ± 2.1%, p < 0.01). Compared with the normal mice, the GMD mice's ITRs were notably declined; however, C. aurantium L. could dose-dependently and significantly reverse it. In addition, in the model of delayed GE induced by loperamide and cisplatin, C. aurantium L. administration reversed the GE deficit. Furthermore, C. aurantium L. significantly reduced gastric cancer proliferation. Conclusion: The results indicate that C. aurantium L. could become a new drug for gastrointestinal prokinetic and gastric cancer therapy.

Abstract
Background Liver cancer is one of the most common digestive tumors. The prescription Zhenzhu Xiaoji decoction (ZZXJD) has a certain effect on the growth and survival of primary liver cancer. Object: This article aimed to explore the effect and molecular mechanism of ZZXJD on liver cancer SMMC-7721 cells. Method The research groups were divided into the model group, ZZXJD group, and cisplatin group. SMMC-7721 cells were treated with different concentrations of ZZXJD-medicated serum for 24 h and 48 h. The cell viability was measured with CCK8 assay, and cell morphology was observed by fluorescence microscope and transmission electron microscope (TEM). Western blot, RT-PCR, and gene chip were used to determine the protein expression level and gene expression level of cells and tumor tissues. Results ZZXJD inhibited the proliferation activity of SMMC-7721 cells in a concentration- and time-dependent manner. The morphological changes of the cell showed apoptosis and autophagy. The gene expression of protein kinase B (AKT), mammalian target of rapamycin (mTOR), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3(STAT3) were downregulated compared with the model group(p < 0.05). The nude mice experiments confirmed that ZZXJD inhibited the growth of tumors in tumor-bearing mice, and the effect increased with the increase of concentration. Conclusion ZZXJD induced autophagy and apoptosis of liver cancer cells via inhibiting AKT/mTOR signaling pathway and JAK2/STAT3 signaling pathway, thereby affecting the growth and survival of liver cancer cells.

Abstract
The development, progression, recurrence, and metastasis of hepatocellular carcinoma (HCC) are closely associated with an abnormal liver-regenerating microenvironment (LRM). Therefore, preventing and reversing an abnormal LRM is a potential therapeutic strategy against HCC. Studies are increasingly focusing on the impact of regeneration, fibrosis, angiogenesis, inflammation, immunomodulation, and hepatic stem cells on HCC development and progression. As a key epigenetic mechanism, DNA methylation is extensively involved in regulating physiological and pathological pathways. In this review, we summarize recent findings on the role of DNA methylation in the fibrotic, angiogenic, inflammatory/immune, and stem cell microenvironments of HCC, and discuss new advances in Traditional Chinese Medicine (TCM) on influencing the abnormal LRM, so as to gain new insights into alleviating the abnormal LRM via regulating DNA methylation by TCM.
