Qian Z, Xin H, Jia Z, Xia J, Tang Y, Li X, Wu H, Fan Y. MiR-760 exerts a critical regulatory role in glioma proliferation, migration, and invasion by modulating MMP2 expression. J Cancer 2024; 15:3076-3084. [PMID: 38706905 PMCID: PMC11064272 DOI: 10.7150/jca.92518] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Accepted: 03/21/2024] [Indexed: 05/07/2024] Open
Abstract
Background: Glioma represents the predominant subtype of brain tumor, characterized by an unfavorable prognosis. Current evidence indicates the involvement of microRNAs (miRNAs) in the initiation and progression of glioma malignancies. While miR-760 has been recognized in the context of tumorigenesis, its precise role in gliomas remains insufficiently explored. Methods: In this investigation, we harnessed the GSE25631 database to scrutinize the aberrant expression profiles of microRNAs, whereby the diminished expression of miR-760 in glioblastoma was validated. Our aim was to delineate the expression patterns of microRNA-760 (miR-760) and probe its prognostic significance within the realm of glioma. Employing quantitative real-time polymerase chain reaction, we ascertained the relative expression levels of miR-760 and MMP2 in glioma cell lines. The impact of miR-760 on cell proliferation, migration, and invasion was assessed through Cell Counting Kit-8 (CCK-8), 5-ethynyl-2'-deoxyuridine (EdU), and Transwell assays. Bioinformatics analysis corroborated the downstream target gene of miR-760. Furthermore, a luciferase reporter experiment was conducted to pinpoint MMP2 as the direct target gene of miR-760. The assessment of MMP2 protein levels was accomplished through Western blotting and immunofluorescence techniques. Result: Our data unequivocally revealed a substantial reduction in miR-760 expression within glioma tissues and cell lines. Heightened miR-760 levels exerted a restraining influence on the proliferation, migration, and invasion capabilities of glioma cell lines. The outcomes of our bioinformatics analysis unveiled the ability of miR-760 to engage with and curtail MMP2 expression. Collectively, these findings posit that miR-760 exerts a restraining influence on glioma growth by orchestrating the upregulation of miR-760 along the miR-760/MMP2 axis. Conclusion: The delineation of the miR-760/MMP2 axis promises to broaden our comprehension of the intricate molecular mechanisms underpinning glioma proliferation and may unveil prospective therapeutic avenues for the management of glioma.

Gu L, Jin X, Liang H, Yang C, Zhang Y. Upregulation of CSNK1A1 induced by ITGB5 confers to hepatocellular carcinoma resistance to sorafenib in vivo by disrupting the EPS15/EGFR complex. Pharmacol Res 2023; 192:106789. [PMID: 37149115 DOI: 10.1016/j.phrs.2023.106789] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 05/02/2023] [Accepted: 05/03/2023] [Indexed: 05/08/2023]
Abstract
Oral multitarget tyrosine kinase inhibitors (TKIs), such as sorafenib, which suppress tumor cell proliferation and tumor angiogenesis, have been approved to treat patients with hepatocellular carcinoma (HCC). Of note, only approximately 30% of patients can benefit from TKIs, and this population usually acquires drug resistance within 6 months. In this study, we intended to explore the mechanism associated with regulating the sensitivity of HCC to TKIs. We revealed that integrin subunit β 5 (ITGB5) is abnormally expressed in HCC and contributes to decreased the sensitivity of HCC to sorafenib. Mechanistically, unbiased mass spectrometry analysis using ITGB5 antibodies revealed that ITGB5 interacts with EPS15 to prevent the degradation of EGFR in HCC cells, which activates AKT-mTOR signaling and the MAPK pathway to reduce the sensitivity of HCC cells to sorafenib. In addition, mass spectrometry analysis showed that CSNK1A1 binds to ITGB5 in HCC cells. Further study indicated that ITGB5 increased the protein level of CSNK1A1 through the EGFR-AKT-mTOR pathway in HCC. Upregulated CSNK1A1 phosphorylates ITGB5 to enhance the interaction between ITGB5 and EPS15 and activate EGFR in HCC cells. Thus, we identified a positive feedback loop between ITGB5-EPS15-EGFR-CSNK1A1 in HCC cells. This finding provides a theoretical basis for the future development of therapeutic strategies to improve the anti-HCC efficacy of sorafenib.

Abstract
The estrous cycle is regulated by rhythmic endocrine interactions of the nervous and reproductive systems, which coordinate the hormonal and ovulatory functions of the ovary. Folliculogenesis and follicle progression require the orchestrated response of a variety of cell types to allow the maturation of the follicle and its sequela, ovulation, corpus luteum formation, and ovulatory wound repair. Little is known about the cell state dynamics of the ovary during the estrous cycle and the paracrine factors that help coordinate this process. Herein, we used single-cell RNA sequencing to evaluate the transcriptome of >34,000 cells of the adult mouse ovary and describe the transcriptional changes that occur across the normal estrous cycle and other reproductive states to build a comprehensive dynamic atlas of murine ovarian cell types and states.

[PMID: 35066068 DOI: 10.1016/j.jep.2022.115020] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 01/10/2022] [Accepted: 01/17/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Brucea javanica (L.) Merr. is a medicinal herb used in China for the prevention and treatment of diseases such as cancer and malaria. Brusatol was isolated from the seeds of Brucea javanica (L.) Merr, brusatol has a wide range of pharmacological effects, including anti-inflammation and anti-cancer effects. AIM OF THE STUDY Renal cell carcinoma is one of the most common urinary system tumours and seriously threatens the lives of patients. We aimed to study the mechanism by which brusatol regulates the growth of renal cancer cells through the PTEN/PI3K/AKT signalling pathway. MATERIALS AND METHODS We chose the A498, ACHN, and OSRC-2 cell lines as experimental models. After intervention with brusatol, CCK-8 experiments and plate cloning experiments were used to detect the cell proliferation ability; flow cytometry was used to detect the cell apoptosis rate; scratch and transwell invasion assays were used to detect the cell migration and invasion ability; qRT-PCR and Western blotting was used to detect PTEN, p-PI3K/PI3K, p-AKT/AKT, Bax, Bcl2, E-cadherin, N-cadherin, and vimentin relative expression. Then, we knocked down the PTEN gene in the three cell lines and again tested the proliferation, apoptosis, migration, and invasion capabilities of each group of cells. RESULTS Brusatol significantly inhibited the proliferation, migration and invasion and increased the rate of apoptosis of the A498, ACHN, and OSRC-2 cell lines, and brusatol significantly increased the expression of PTEN mRNA and protein, and inhibited the expression of p-PI3K and p-AKT. Moreover, knockdown of PTEN significantly reduced the inhibitory effect of brusatol on the growth of renal cancer cells. CONCLUSION Our research results show that brusatol has an effective inhibitory effect on the growth of A498, ACHN, and OSRC-2 renal cancer cell lines, and this effect is likely to be produced by regulating the PTEN/PI3K/AKT signalling pathway.
