Abstract
OBJECTIVE To explore the correlation of CPNE3 expression with long-term prognosis of patients with gastric cancer (GC) and the possible mechanism. METHODS We retrospectively collected the data of 104 GC patients undergoing radical surgery in our hospital from February, 2013 to October, 2017. TCGA database and immunohistochemistry were used to analyze CPNE3 expression level in GC tissues and its effects on tumor progression and long-term prognosis of the patients. GO analysis was performed to predict the biological role of CPNE3 in GC. We also conducted cell experiments with MGC803 cells and observed the effects of CPNE3 knockdown, CPNE3 overexpression and LY294002 (a PI3K/AKT inhibitor) treatment on cell apoptosis and cellular expressions of apoptotic proteins using flow cytometry and Western blotting. RESULTS TCGA analysis and immunohistochemistry both showed high expressions of CPNE3 in GC (P < 0.05). The patients with high CPNE3 expressions had a reduced 5-year survival (P < 0.01), and a high CPNE3 expression, CEA level≥5 μg/L, CA19-9 level ≥37 kU/L, T3-T4 stage, and N2-N3 stage were all independent risk factors for a lowered 5-year survival rate after surgery. The sensitivity and specificity of CPNE3 for predicting 5-year mortality was 79.59% and 74.55%, respectively (P < 0.05). GO analysis predicted that CPNE3 negatively regulated GC cell apoptosis. In MGC803 cells, CPNE3 knockdown significantly increased cell apoptosis, enhanced Bax and Cleaved Caspase-3 expressions and decreased Bcl-2 expression, while CPNE3 overexpression produced the opposite results (P < 0.05). The cellular expressions of p-PI3K and p-AKT were significantly decreased following CPNE3 knockdown and increased following CPNE3 overexpression (P < 0.05). Treatment with LY294002 obviously attenuated the inhibitory effect of CPNE3 overexpression on apoptosis of MGC803 cells (P < 0.05). CONCLUSION CPNE3 is highly expressed in GC tissues and affects the long-term prognosis of the patients possibly by inhibiting GC cell apoptosis through activation of PI3K/AKT signaling.

DHW-208, A Novel Phosphatidylinositol 3-Kinase (PI3K) Inhibitor, Has Anti-Hepatocellular Carcinoma Activity Through Promoting Apoptosis and Inhibiting Angiogenesis. Front Oncol 2022; 12:955729. [PMID: 35903690 PMCID: PMC9315107 DOI: 10.3389/fonc.2022.955729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 06/13/2022] [Indexed: 11/29/2022] Open
Abstract
Hepatocellular carcinoma (HCC) is one of the most common tumors worldwide with high prevalence and lethality. Due to insidious onset and lack of early symptoms, most HCC patients are diagnosed at advanced stages without adequate methods but systemic therapies. PI3K/AKT/mTOR signaling pathway plays a crucial role in the progression and development of HCC. Aberrant activation of PI3K/AKT/mTOR pathway is involved in diverse biological processes, including cell proliferation, apoptosis, migration, invasion and angiogenesis. Therefore, the development of PI3K-targeted inhibitors is of great significance for the treatment of HCC. DHW-208 is a novel 4-aminoquinazoline derivative pan-PI3K inhibitor. This study aimed to assess the therapeutic efficacy of DHW-208 in HCC and investigate its underlying mechanism. DHW-208 could inhibit the proliferation, migration, invasion and angiogenesis of HCC through the PI3K/AKT/mTOR signaling pathway in vitro. Consistent with the in vitro results, in vivo studies demonstrated that DHW-208 elicits an antitumor effect by inhibiting the PI3K/AKT/mTOR-signaling pathway with a high degree of safety in HCC. Therefore, DHW-208 is a candidate compound to be developed as a small molecule PI3K inhibitor for the treatment of HCC, and our study provides a certain theoretical basis for the treatment of HCC and the development of PI3K inhibitors.
