Biosci.

However, its speciffc and potential mechanism is uncertain in AML. In this research, we investigated the role of ANRIL in cell proliferation, apoptosis, and the underlying mechanism in AML cells. Methods: ANRIL expression was quantified by real-time quantitative polymerase chain reaction (RT-qPCR). Kasumi-1 cells were transfected with LV-ANRIL plasmid to upregulate ANRIL expression, with or without co-transfection with a G Protein-Coupled Receptor Kinase 2 (GRK2) siRNA. Additionally, these cells were transfected with sh-ANRIL plasmid to inhibit ANRIL expression, with or without co-transfection with a GRK2 overexpression plasmid. Cell proliferation and apoptosis were determined using the cell counting kit-8 (CCK8) and flow cytometry. Protein expression levels of phosphatidylinositide 3-kinases (PI3K), protein kinase B (AKT), phosphorylated-Akt (p-AKT), Bcl-2-associated protein x (BAX), B-cell leukemia\/lymphoma 2 protein (BCL-2), proliferating cell nuclear antigen (PCNA), cleaved caspase-3, and GRK2 were detected by western blot. The RNA-binding protein immunoprecipitation (RIP) assay was conducted to investigate the interaction between ANRIL and GRK2. Results: ANRIL expression was increased in Kasumi-1 cells. ANRIL upregulation expression promoted cell proliferation and inhibited apoptosis. Furthermore, its upregulation led to increased expressions of PI3K, AKT, p-AKT, PCNA, and BCL-2, and decreased expression of BAX in Kasumi-1 cells. Additionally, transfection with GRK2 siRNA attenuated the promoting effect of LV-ANRIL on Kasumi-1 cells proliferation and the PI3K\/AKT pathway, increased BAX and cleaved caspase-3 expressions, and decreased BCL-2 and PCNA expressions. GRK2 overexpression reversed the inhibitory effect of sh-ANRIL on cell proliferation and the PI3K\/AKT pathway. Furthermore, it promoted BCL-2 and PCNA expressions, and inhibited BAX and cleaved caspase-3 expressions. RIP assay confirmed the physical interaction between ANRIL and GRK2. Conclusion: The GRK2 protein-mediated ANRIL, increasing Kasumi-1 cell proliferation and inhibiting apoptosis by activating the PI3K\/AKT\/BCL-2 pathway.<\/jats:p>","DOI":"10.31083\/j.fbl2910362","type":"journal-article","created":{"date-parts":[[2024,10,30]],"date-time":"2024-10-30T07:40:52Z","timestamp":1730274052000},"source":"Crossref","is-referenced-by-count":4,"title":["GRK2 Protein Mediates the ANRIL, a lncRNA, to Affect the Proliferation and Apoptosis of Kasumi-1 Cells"],"prefix":"10.31083","volume":"29","author":[{"given":"Siqi","family":"Wang","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengsi","family":"Zhang","sequence":"first","affiliation":[{"name":"Guizhou Center for Disease Control and Prevention, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huali","family":"Hu","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianxia","family":"Xu","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinxin","family":"Zhang","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wu","family":"Zhou","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fahua","family":"Deng","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaming","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Hematology, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenlong","family":"Hu","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuancheng","family":"Liu","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai","family":"Huang","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"},{"name":"Department of Clinical Biochemistry, School of Clinical Laboratory Science, Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sixi","family":"Wei","sequence":"first","affiliation":[{"name":"Center for Clinical Laboratories, The Affiliated Hospital of Guizhou Medical University, 550004 Guiyang, Guizhou, China"},{"name":"Department of Clinical Biochemistry, School of Clinical Laboratory Science, Guizhou Medical University, 550004 Guiyang, Guizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2024,10,21]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"D\u00f6hner H, Weisdorf DJ, Bloomfield CD.
