Vascular endothelial cell-derived exosomal miR-30a-5p inhibits lung adenocarcinoma malignant progression by targeting CCNE2.

Carcinogenesis 2021 Jun 15. Epub 2021 Jun 15.

Department of Oncology, The First Affiliated Hospital of Soochow University, Jiangsu, China, Department of Thoracic Surgery, Cancer Hospital of the University of Chinese Academy of Sciences (Zhejiang Cancer Hospital), Zhejiang Cancer Hospital, Hangzhou, Zhejiang, China, Institute of Cancer and Basic Medicine (IBMC) Chinese Academy of Sciences, Gongshu District, Hangzhou, China.

This study tried to explore the molecular mechanism underlying progression of lung adenocarcinoma (LUAD), and discuss the extracellular communication between cancer cells and vascular endothelial cells. Roughly, differential analysis was carried out to note that miR-30a-5p was lowly expressed in LUAD while CCNE2 was highly expressed. Cell functional experiments demonstrated that overexpressed miR-30a-5p led to suppressed cell abilities in proliferation, migration and invasion. Read More

Inhibition of the Ras/ERK1/2 pathway contributes to the protective effect of ginsenoside Re against intimal hyperplasia.

Food Funct 2021 Jun 12. Epub 2021 Jun 12.

Department of Pharmacology, School of Basic Medical Sciences, Xi'an Jiaotong University, Xi'an, Shaanxi 710061, China.

Neointimal hyperplasia is the major cause of carotid stenosis after vascular injury, which restricts the long-term efficacy of endovascular treatment and endarterectomy in preventing stenosis. Ginsenoside Re (Re) is a major active ingredient of ginseng having multifaceted pharmacological effects on the cardiovascular system, and is a potential treatment for restenosis. In this study, we demonstrated that Re treatment significantly inhibited vascular injury-induced neointimal thickening, reduced the intimal area and intima/media (I/M) ratio, increased the lumen area, and inhibited pro-inflammatory cytokines.

Cancer Cell Migration in Collagen-hyaluronan Composite Extracellular Matrices.

Acta Biomater 2021 Jun 8. Epub 2021 Jun 8.

Department of Chemical and Biological Engineering, Iowa State University; Department of Genetics, Development and Cell Biology, Iowa State University. Electronic address:

Hyaluronan (HA) is a key component in the tumor microenvironment (TME) that participates in cancer growth and invasiveness. While the molecular weight (MW) dependent properties of HA can cause tumor-promoting and -repressing effects, the elevated levels of HA in the TME impedes drug delivery. The degradation of HA using hyaluronidases (HYALs), resulting in fragments of HA, is a way to overcome this, but the consequences of changes in HA molecular weight and concentration is currently unknown.

The Role of R-Ras Proteins in Normal and Pathologic Migration and Morphologic Change.

Am J Pathol 2021 Jun 7. Epub 2021 Jun 7.

Department of Pathology and Laboratory Medicine, Medical University of South Carolina, Charleston, SC 29425-9080. Electronic address:

The contributions that the R-Ras subfamily (R-Ras, R-Ras2/TC21 and M-Ras) of small GTP-binding proteins make to normal and aberrant cellular functions have historically been poorly understood. However, this has begun to change with the realization that all three R-Ras subfamily members are occasionally mutated in Noonan syndrome, a RASopathy characterized by the development of hematopoietic neoplasms and abnormalities affecting the immune, cardiovascular and nervous systems. Consistent with the abnormalities seen in Noonan syndrome, a host of new studies have implicated R-Ras proteins in physiologic and pathologic changes in cellular morphology, adhesion, and migration in the cardiovascular, immune, and nervous systems.

Autophagy modulates FSS-induced epithelial-mesenchymal transition in hepatocellular carcinoma cells.

Mol Carcinog 2021 Jun 9. Epub 2021 Jun 9.

Institute of Biomedical Engineering, West China School of Basic Medical Sciences & Forensic Medicine, Sichuan University, Chengdu, China.

Hepatocellular carcinoma is a highly fatal disease and threatens human health seriously. Fluid shear stress (FSS), which is caused by the leakage of plasma from abnormally permeable tumor blood vessels and insufficient lymphatic drainage, has been identified as contributing pathologically to cancer metastasis. Autophagy and epithelial-mesenchymal transition (EMT) are both reported to be involved in cancer cell migration and invasion, but little has been revealed about the interaction between autophagy and EMT under a tumor mechanical microenvironment.

Adv Sci (Weinh) 2021 06 18;8(11):e2003558. Epub 2021 Mar 18.

State Key Laboratory of Oncogenes and Related Genes, Shanghai Cancer Institute, School of Biomedical Engineering, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, 200032, China.

The binding of amyloid precursor protein (APP) expressed on tumor cells to death receptor 6 (DR6) could initiate the necroptosis pathway, which leads to necroptotic cell death of vascular endothelial cells (ECs) and results in tumor cells (TCs) extravasation and metastasis. This study reports the first inhibitor of DR6/APP interaction as a novel class of anti-hematogenous metastatic agent. By rationally utilizing three combined strategies including selection based on phage display library, d-retro-inverso modification, and multiple conjugation of screened peptidomimetic with 4-arm PEG, the polymer-peptidomimetic conjugate PEG-tAHP-DRI (tetra-(D-retro-inverso isomer of AHP-12) substitued 4-arm PEG ) is obtained as the most promising agent with the strongest binding potency (K  = 51.

Roles for growth factors and mutations in metastatic dissemination.

Biochem Soc Trans 2021 Jun 8. Epub 2021 Jun 8.

Department of Biological Regulation, Weizmann Institute of Science, Rehovot, Israel.

Cancer is initiated largely by specific cohorts of genetic aberrations, which are generated by mutagens and often mimic active growth factor receptors, or downstream effectors. Once initiated cells outgrow and attract blood vessels, a multi-step process, called metastasis, disseminates cancer cells primarily through vascular routes. The major steps of the metastatic cascade comprise intravasation into blood vessels, circulation as single or collectives of cells, and eventual colonization of distant organs. Read More
