Targeting Pokemon is a novel strategy to suppress cancer aggressiveness of non-small cell lung cancer: Identification of Pokemon as ideal target for developing anti-NSCLC drugs. Arch Biochem Biophys 2023; 742:109637. [PMID: 37182800 DOI: 10.1016/j.abb.2023.109637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 05/10/2023] [Accepted: 05/11/2023] [Indexed: 05/16/2023]
Abstract
Although it is widely reported that Pokemon acts as an oncogene in the pathogenesis of multiple cancers, but its role and detailed molecular mechanisms in regulating non-small cell lung cancer (NSCLC) progression have not been fully delineated. Here, by performing Real-Time qPCR analysis, we verified that Pokemon was high-expressed in NSCLC tissues and cells, compared to the corresponding normal lung tissues and epithelial cells. Then, the small interfering RNA (siRNA) for Pokemon was transfected into the NSCLC cells to verify its biological functions, and our results suggested that silencing of Pokemon suppressed the malignant phenotypes, including cell viability, mitosis, colony formation, epithelial-mesenchymal transition (EMT), mobility and cancer stem cell (CSC) properties in NSCLC cells. Mechanistically, we confirmed that knockdown of Pokemon decreased the expression levels of phosphorylated Akt (p-Akt), phosphorylated GSK-3β (p-GSK-3β) and Snail to inactivate the oncogenic Akt/GSK-3β/Snail signal pathway, and deletion of Snail also had similar effects to hamper the development of NSCLC. Next, our rescuing experiments validated that Pokemon ablation-induced suppressing effects on NSCLC cell malignancy were all abrogated by overexpressing Snail. Finally, the in vivo experiments confirmed that silencing of Pokemon downregulated Snail to hamper tumorigenesis of NSCLC cells in xenograft tumor-bearing mice models. Taken together, we firstly uncovered the underlying mechanisms by which the Pokemon/Akt/GSK-3β/Snail signal pathway contributed to the development of NSCLC, and this signal pathway could be potentially used as therapeutic targets for the development of personalized anti-NSCLC drugs.

Oral Submucous Fibrosis: Etiological Mechanism, Malignant Transformation, Therapeutic Approaches and Targets. Int J Mol Sci 2023; 24:ijms24054992. [PMID: 36902423 PMCID: PMC10003551 DOI: 10.3390/ijms24054992] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 11/28/2022] [Accepted: 02/23/2023] [Indexed: 03/08/2023] Open
Abstract
Oral submucosal fibrosis (OSF) is a chronic, progressive and potentially malignant oral disorder with a high regional incidence and malignant rate. With the development of the disease, the normal oral function and social life of patients are seriously affected. This review mainly introduces the various pathogenic factors and mechanisms of OSF, the mechanism of malignant transformation into oral squamous cell carcinoma (OSCC), and the existing treatment methods and new therapeutic targets and drugs. This paper summarizes the key molecules in the pathogenic and malignant mechanism of OSF, the miRNAs and lncRNAs with abnormal changes, and the natural compounds with therapeutic effects, which provides new molecular targets and further research directions for the prevention and treatment of OSF.

[PMID: 37021272 PMCID: PMC10068493 DOI: 10.1016/j.jds.2023.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 01/08/2023] [Indexed: 01/25/2023] Open
Abstract
Background/purpose Emerging evidence has shown that various failures in cancer therapy, such as drug resistance, metastasis, and cancer relapse are attributed to cancer stem cells (CSCs). Also, growing attention has been paid to the regulation of non-coding RNAs in cancer stemness. Here, we aimed to investigate the contribution of LINC01296 in the modulation of oral CSCs. Materials and methods The phenotypic assays including migration, invasion, and colony-forming abilities were carried out in CSCs of two types of oral cancer cells (SAS and GNM) following the knockdown of LINC01296. In addition, the percentage of cells expressing stemness marker, ALDH1, and drug resistance marker, ABCG2, was examined as well as the self-renewal capacity after silencing of LINC01296. Moreover, a luciferase reporter was used to validate the direct interaction between LINC01296 and miR-143. Results Our results showed that LINC01296 was significantly overexpressed in oral cancer tissues and positively correlated with stemness markers. The phenotypic and flow cytometry assays demonstrated that suppression of LINC01296 reduced the aggressiveness, cancer stemness features, and colony-forming and self-renewal abilities in oral CSCs. Furthermore, we demonstrated that LINC01296 may enhance cancer stemness features through suppression of the effect of miR-143. Conclusion Silencing of LINC01296 may be a promising direction for oral cancer therapy by reducing cancer stemness via regulation of miR-143.

Front Oncol 2022; 12:1026278. [PMID: 36387165 PMCID: PMC9650078 DOI: 10.3389/fonc.2022.1026278] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 10/12/2022] [Indexed: 12/02/2022] Open
Abstract
Solid tumors can be divided into benign solid tumors and solid malignant tumors in the academic community, among which malignant solid tumors are called cancers. Cancer is the second leading cause of death in the world, and the global incidence of cancer is increasing yearly New cancer patients in China are always the first. After the concept of stem cells was introduced in the tumor community, the CSC markers represented by ALDH1 have been widely studied due to their strong CSC cell characteristics and potential to be the driving force of tumor metastasis. In the research results in the past five years, it has been found that ALDH1 is highly expressed in various solid cancers such as breast cancer, lung cancer, colorectal cancer, liver cancer, gastric cancer, cervical cancer, esophageal cancer, ovarian cancer, head,and neck cancer. ALDH1 can activate and transform various pathways (such as the USP28/MYC signaling pathway, ALDH1A1/HIF-1α/VEGF axis, wnt/β-catenin signaling pathway), as well as change the intracellular pH value to promote formation and maintenance, resulting in drug resistance in tumors. By targeting and inhibiting ALDH1 in tumor stem cells, it can enhance the sensitivity of drugs and inhibit the proliferation, differentiation, and metastasis of solid tumor stem cells to some extent. This review discusses the relationship and pathway of ALDH1 with various solid tumors. It proposes that ALDH1 may serve as a diagnosis and therapeutic target for CSC, providing new insights and new strategies for reliable tumor treatment.
