Abstract
BACKGROUND AND OBJECTIVE The morbidity rate of non-small cell lung cancer (NSCLC) increases with age, highlighting that NSCLC is a serious threat to human health. The aim of this study was mainly to describe the role of exosomal miR-101-3p derived from bone marrow mesenchymal stem cells (BMSCs) in NSCLC. METHODS A549 or NCI-H1703 cells (1×105/mouse) were injected into nude mice to establish an NSCLC animal model. RTqPCR, Western blotting and comet assays were used to assess the changes in gene expression, proteins and DNA damage repair. RESULTS miR-101-3p and RAI2 were found to be expressed at low levels in NSCLC, while EZH2 was highly expressed. In terms of function, miR-101-3p downregulated EZH2. In addition, exosomal miR-101-3p derived from BMSCs promoted the expression of RAI2, inhibited DNA damage repair, and inhibited the activation of the PI3K/AKT/mTOR signaling pathway by inhibiting EZH2, thereby promoting autophagy and decreasing cell viability and finally enhancing the sensitivity of NSCLC to radiotherapy and inhibiting the malignant biological behavior of NSCLC. CONCLUSION Exosomal miR-101-3p derived from BMSCs can inhibit DNA damage repair, promote autophagy, enhance the radiosensitivity of NSCLC, and inhibit the progression of NSCLC by inhibiting EZH2.

Abstract
Radiotherapy has been used for decades in the treatment of liver cancer. We previously found that adiponectin receptor (AdipoR1) is a prognostic biomarker for hepatoma carcinoma (HCC) after stereotactic body radiation therapy (SBRT) and blocking AdipoR1 enhances radiation sensitivity in hepatoma carcinoma cells. In the current study, we aimed to elucidate the roles of AdipoR1 in ionizing radiation- (IR-) induced radiosensitivity by activating ferroptosis pathway in HCC cells. We found that IR upregulated the expression of AdipoR1 and furthermore promoted the protein stability of transcription factor Nrf2, Nrf2 binded to the xCT promoter and increased xCT transcription and expression, and this directly contributed to the protective function in the early stage of radiation in HCC cells. AdipoR1 knockdown significantly inhibited expression of Nrf2 and xCT and, furthermore, increased both IR- and erastin-induced ferroptosis, which could be abolished by the rescue of Nrf2 and xCT. For the first time, we found that radiation-induced ferroptosis was mediated by AdipoR1-Nrf2-xCT pathway in HCC cells. These results provide new insights to the development and application of novel therapeutic strategies for hepatoma carcinoma.

Dose Response 2022; 20:15593258221097589. [PMID: 35547468 PMCID: PMC9083052 DOI: 10.1177/15593258221097589] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Accepted: 04/10/2022] [Indexed: 11/15/2022] Open
Abstract
Objective So far there are still no effective immediate-early markers for assessing the efficacy of Stereotactic Body Radiation Therapy (SBRT). To find effective biomarkers for accurate assessment of the efficacy of SBRT in patients with primary liver cancer, we conducted this study including retrospective part and prospective part. Material and Methods 589 patients with primary liver cancer were included at Ruikang Hospital affiliated to Guangxi Medical University from January 2012 to December 2018. Follow-up was conducted, clinical information and a total of 17 patients with 51 blood samples (before SBRT, before discharge and 2 months after SBRT) were collected. mRNAs profiles on 2 patients with 6 blood samples were detected by high-throughput sequencing, followed by qPCR verification on 15 patients with 45 blood samples. Results The commonly used serum biomarkers such as AFP, CEA, and CA125 shown low prognostic value in distinguishing survival group and death group, indicated by low AUC (less than .7) and Youden indexes (less than .5). Based on high-throughput sequencing of test group and qPCR detection of another verification group, we found 16 up-regulated and 12 downregulated genes after SBRT. Among them, ADIPOR1 and EPB42 showed significantly different between effective and ineffective group after SBRT, ROC suggested that based on the optimal threshold of .5838, ADIPOR1 shown a sensitivity of 100% and a specificity of 83.33% to distinguish effective from ineffective group. And EPB42 had a sensitivity of 75% and a specificity of 100% at the optimal threshold of 1.3817. In addition, GSEA showed that high expression of ADIPOR1 was mainly related to Mismatch repair, Circadian rhythm, Protein processing in endoplasmic reticulum, DNA replication, and Fanconi anemia pathways. Conclusion ADIPOR1 in whole blood is a promising candidate to act as prognostic biomarker for predication of SBRT outcomes in primary liver cancer patients.
