Cancer-associated fibroblasts promote tumor cell growth via miR-493-5p in intrahepatic cholangiocarcinoma. Cancer Sci 2023; 114:937-947. [PMID: 36369960 PMCID: PMC9986089 DOI: 10.1111/cas.15644] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 10/18/2022] [Accepted: 11/09/2022] [Indexed: 11/14/2022] Open
Abstract
The association between tumor microenvironment (TME) and cancer-associated fibroblasts (CAFs) in intrahepatic cholangiocarcinoma (ICC) progression is poorly understood. This study aimed to reveal whether specific microRNAs (miRNAs) in extracellular vesicles (EVs) derived from CAFs were involved in ICC progression. Conditioned medium (CM) and EVs in the CM of CAFs and normal fibroblasts (NFs) derived from ICC specimens were used to investigate the effects on tumor cell lines. miRNA microarray assay was used to examine the miRNAs of EVs derived from CAFs and NFs in ICC, and the effects of miR-493-5p on tumor cell lines were examined. Additionally, databases were used to identify miR-493-5p targets, and the relationship between prognosis of ICC patients and cocaine- and amphetamine-regulated transcript propeptide (CARTPT), one of the targets of miR-493-5p, expression in ICC tissues was retrospectively analyzed. Compared with NF-derived CM and EVs, CAF-derived CM and EVs promoted cell lines in proliferation, scratch, migration, and invasion assays. miRNA microarray analysis revealed that miR-493-5p was significantly increased in CAF-derived EVs compared to NF-derived EVs. Tumor cell lines transfected with miR-493-5p were promoted in proliferation and scratch assays. Immunohistochemical staining was performed on 76 ICC specimens; both overall and recurrence-free survival rates were significantly worse in the CARTPT-negative group. Univariate and multivariate analyses showed that low CARTPT expression was an independent poor prognostic factor for overall and recurrence-free survival. Overall, our data suggest that CAFs in the ICC TME suppress CARTPT in tumor cells and promote tumor cells via miR-493-5p in EVs.

Post-treatment with cocaine- and amphetamine-regulated transcript enhances infarct resolution, reinnervation, and angiogenesis in stroke rats - an MRI study. NMR IN BIOMEDICINE 2016; 29:361-370.

Abstract
Recent studies have shown that post-treatment with cocaine- and amphetamine-regulated transcript (CART) has neuroregenerative effects in animal models of stroke. The purpose of this study was to characterize CART-mediated neuronal and vascular repairments using non-invasive MRI techniques. Adult male rats were subjected to a 90 min middle cerebral artery occlusion (MCAo). Animals were separated into two groups with similar infarction sizes, measured by T2 -weighted MRI on Day 2 after MCAo, and were treated with CART or vehicle intranasally from Day 3 to Day 12. Diffusion tensor imaging was used to examine changes in plasticity of white matter elements. Susceptibility-weighted imaging (SWI) was used to measure angiogenesis. Post-treatment with CART significantly increased fractional anisotropy (FA) in lesioned cortex on Days 10 and 25 post stroke. A significant correlation between the behavioral recovery in body asymmetry and the change in FA was shown, suggesting that behavioral recovery was associated with reinnervation to the lesioned hemisphere. CART also increased the intensity of SWI and the immunoreactivity of the vascular marker alpha-smooth muscle actin in lesioned cortex. Together, our data support a non-invasive treatment strategy for stroke through angiogenesis and reinnervation by CART. Copyright © 2016 John Wiley & Sons, Ltd.
