The Roles of Cytoplasmic Polyadenylation Element Binding Protein 1 in Tumorigenesis.

BACKGROUND: CPEB1 is an alternative polyadenylation binding protein that promotes or suppresses the expression of related mRNAs and proteins by binding to a highly conserved Cytoplasmic Polyadenylation Element (CPE) in the mRNAs 3'UTR. It is found to express abnormally in multiple tumors and affect tumorigenesis through many pathways. This review summarizes the functions and mechanisms of CPEB1 in a variety of cancers and suggests new directions for future related treatments. METHODS: A total of 95 articles were eligible for inclusion based on the year, quality of the research, and the strength of association with CPEB1. In this review, current research about how CPEB1 affects the initiation and progression of glioblastoma, breast cancer, hepatocellular carcinoma, gastric cancer, colorectal cancer, non-small cell lung cancer, prostate cancer, and melanoma are dissected, and the biomedical functions and mechanisms are summarized. RESULTS: CPEB1 mostly presents as a tumor suppressor for breast cancer, endometrial carcinoma, hepatocellular carcinoma, non-small cell lung cancer, prostate cancer, and melanoma. However, glioblastoma, gastric cancer, and colorectal cancer it exhibit two opposing properties of tumorigenesis, either promoting or inhibiting it. CONCLUSION: CPEB1 is likely to serve as a target and dynamic detection index or prognostic indicator for its function of apoptosis, activity, proliferation, migration, invasion, stemness, drug resistance, and even ferroptosis in various cancers.

SNHG11: A New Budding Star in Tumors and Inflammatory Diseases.

BACKGROUND: Long non-coding RNAs (lncRNAs) are transcripts that are over 200 nucleotides in length and lack protein-coding potential. Despite their name, lncRNAs have important regulatory roles in transcription, translation, and protein function by interacting with DNA, RNA, and protein molecules. Small nucleolar RNAs (snoRNAs), found in various tumors, are encoded by lncRNAs and have gained attention in recent research. The lncRNAs, encoding snoRNAs are known as small nucleolar RNA host genes (SNHGs), a newly identified class of lncRNAs. SNHG11, a specific SNHG, is a critical regulatory factor involved in various biological processes. Accumulating evidence suggests that SNHG11 can impact tumor development and inflammatory diseases by modulating downstream gene expression through chromatin modification, transcription, or post-transcriptional mechanisms. The expression levels of SNHG11 vary significantly in different normal tissues, tumors, and stages of tumor development. Currently, treatment options for advanced cancers are mainly palliative and lack curative potential. OBJECTIVES: This review aims to explore the modifications and functions of lncRNA SNHG11 in various tumors and inflammatory diseases. Through a comprehensive analysis of relevant literature on SNHG11 in PubMed, the review aims to provide a comprehensive description of the roles of SNHG11 in known tumors and inflammatory diseases and elucidate the specific mechanism's underlying functions. The changes in SNHG11 expression in tumors and inflammatory diseases can serve as early biomarkers, therapeutic targets, and prognostic indicators. Improving the clinical detection, staging, treatment, and prognosis of tumors is of great value. Additionally, the structural modifications of SNHG11 can potentially enhance its function as a drug carrier to maximize the therapeutic potential of drugs. Furthermore, understanding the specific mechanisms of SNHG11 in tumors and inflammatory diseases may provide new ways for targeted therapy. MATERIALS AND METHODS: Relevant studies were retrieved and collected from the PubMed system. SNHG11 was identified as the research object, and research literature on SNHG11 in the past ten years was analyzed to determine its strong association with the onset and progression of various diseases. The precise mechanisms of SNHG11's mode of action were reviewed, and references were further determined based on their impact factors for comprehensive analysis. RESULTS: Through review and analysis, it was found that SNHG11 is involved in a wide range of tumors and inflammatory diseases through its high expression, including lung cancer, colorectal cancer, prostate cancer, hepatocellular carcinoma, triple-negative breast cancer, gastric cancer, glioma, ovarian cancer, pancreatic cancer, acute pancreatitis, and ischemic stroke, but with lower expression in virus myocarditis. SNHG11 is abnormally expressed in cells of these tumors and inflammatory diseases mainly contributes to disease proliferation, metastasis, ceRNA activity, miRNA sponging, drug resistance, and tumor prognosis. However, the specific mechanisms of SNHG11 in tumors and inflammatory diseases require further detailed exploration. Understanding the known regulatory mechanisms can expand the scope of clinical applications and promote early clinical detection, monitoring, and treatment. CONCLUSION: LncRNA SNHG11 can serve as an early diagnostic biomarker, therapeutic target, and prognostic indicator in various diseases, particularly tumors. SNHG11 plays a crucial role in the occurrence and development of tumors and inflammatory diseases through various mechanisms, which has significant implications for clinical diagnosis and treatment.

Long non-coding RNA has attracted the interest of researchers as a relevant factor that can influence human cancers. As an oncogene and suppressor gene, it has numerous pathways and is closely related to the pathophysiology of human diseases. Meanwhile, it may become a novel treatment option and target for tumor treatment. CRNDE is the gene symbol for Colorectal Neoplasia Differentially Expressed (non-protein-coding) since it was found to be considerably higher in colorectal cancer when it was first discovered. It's transcribed from human chromosome 16. Many studies have shown that it is intimately linked to the etiology of many tumors and malignancies. According to the paper, the biological function and pathophysiological mechanism of CRNDE in tumors have been studied extensively in recent years. PubMed served as an essential platform for conducting literature searches and related analyses. CRNDE, a long non-coding RNA closely related to tumors, was highly expressed in many tumor cells.

The Functions of EphA1 Receptor Tyrosine Kinase in Several Tumors.

BACKGROUND: Eph receptors tyrosine kinase (RTK) were identified in 1987 from hepatocellular carcinoma cell lines and were the largest known subfamily of RTK. Eph receptors can be divided into two categories, EphA and EphB, based on their structure and receptor-ligand specificity. EphA can be divided into 10 species (EphA 1-10) and EphB into 6 species (EphB1-6). Similarly, the ligands of Eph receptors are Ephrins. Ephrins also can be divided into Ephrin A and Ephrin B, of which there are five species(Ephrin-A1-5) and three species(Ephrin-B1-3). Among the Eph receptors, EphA1 has been the least studied so far. As far as we know, Eph receptors are involved in multiple pathologies, including cancer progression, tumor angiogenesis, intestinal environmental stability, the lymph node system, neurological disease, and inhibition of nerve regeneration after injury. There is a link between EphA1, integrin and ECM- related signal pathways. Ephrin-A1 is a ligand of the EphA1 receptor. EphA1 and ephrin-A1 functions are related to tumor angiogenesis. EphA1 and ephrin-A1 also play roles in gynecological diseases. Ephrin-A1 and EphA1 receptors regulate the follicular formation, ovulation, embryo transport, implantation and placental formation, which are of great significance for the occurrence of gynecological tumor diseases. EphA1 has been identified as an oncoprotein in various tumors and has been associated with the prognosis of various tumors in recent years. EphA1 is considered a driver gene in tumor genomics. There are significant differences in EphA1 expression levels in different types of normal tissues and tumors and even in different stages of tumor development, suggesting its functional diversity. Changes at the gene level in cell biology are often used as biological indicators of cancer, known as biomarkers, which can be used to provide diagnostic or prognostic information and are valuable for improving the detection, monitoring and treatment of tumors. However, few prognostic markers can selectively predict clinically significant tumors with poor prognosis. These malignancies are more likely to progress and lead to death, requiring more aggressive treatment. Currently available treatments for advanced cancer are often ineffective, and treatment options are mainly palliative. Therefore, early identification and treatment of those at risk of developing malignant tumors are crucial. Although pieces of evidence have shown the role of EphA1 in tumorigenesis and development, its specific mechanism is still unknown to a great extent. OBJECTIVE: This review reveals the changes and roles of EphA1 in many tumors and cancers. The change of EphA1 expression can be used as a biological marker of cancer, which is valuable for improving tumor detection, monitoring and treatment and can be applied to imaging. Studies have shown that structural modification of EphA1 could make it an effective new drug. EphA1 is unique in that it can be considered a prognostic marker in many tumors and is of important meaning for clinical diagnosis and operative treatment. At the same time, the study of the specific mechanism of EphA1 in tumors can provide a new way for targeted therapy. METHODS: Relevant studies were retrieved and collected through the PubMed system. After determining EphA1 as the research object, by analyzing research articles on EphA1 in the PubMed system in recent 10 years, we found that EphA1 was closely connected with the occurrence and development of tumors and further determined the references according to the influencing factors for review and analysis. RESULTS: EphA1 has been identified as a cancer protein in various tumors, such as hepatocellular carcinoma, nasopharyngeal carcinoma, ovarian cancer, gastric cancer, colorectal cancer, clear cell renal cell carcinoma, esophageal squamous cell carcinoma, breast cancer, prostate cancer and uveal melanoma. EphA1 is abnormally expressed in these tumor cells, which mainly plays a role in cancer progression, tumor angiogenesis, intestinal environmental stability, the lymph node system, nervous system diseases and gynecological diseases. In a narrow sense, EphA1 is especially effective in breast cancer in terms of gynecological diseases. However, the specific mechanism of EphA1 leading to the change of cancer cells in some tumors is not clear, which needs further research and exploration. CONCLUSION: RTK EphA1 can be used as a biomarker for tumor diagnosis (especially a prognostic marker), an indispensable therapeutic target for new anti-tumor therapies, and a novel anti-tumor drug.

ITGA9: Potential Biomarkers and Therapeutic Targets in Different Tumors.

Integrins are a class of cell surface adhesion molecules composed of α subunit (ITGA) and ß subunit (ITGB). They belong to heterodimer transmembrane glycoproteins. Their main function in organisms is as the receptor of cell adhesion molecules (CAMs) and extracellular matrix (ECM). According to the current research integration analysis, integrin α9 (ITGA9) is one of the integrin subunits, and there are few studies on ITGA9 among integrins. ITGA9 can improve cell migration and regulate various cellular biological functions, such as tumor cell proliferation, adhesion, invasion, and angiogenesis. However, its abnormal expression mechanism in cancer and its specific role in tumor growth and metastasis are still unknown to a great extent. This review reveals the role of ITGA9 in the complex pathogenesis of many tumors and cancers, providing a new direction for the treatment of tumors and cancers. Relevant studies were retrieved and collected through the PubMed system. After determining ITGA9 as the research object, we found a close relationship between ITGA9 and tumorigenesis by analyzing the research articles on ITGA9 in the PubMed system in the last 15 years and further determined the references mainly based on the influencing factors of the articles. Thus, the role of ITGA9 in tumor and cancer genesis, proliferation, and metastasis was reviewed and analyzed. ITGA9 is an integrin subunit, which has been proved to be abnormally expressed in many tumors. After sorting and analyzing the research data, it was found that the abnormal expression of ITGA9 in a variety of tumors, including glioblastoma, rhabdomyosarcoma, melanoma, hepatocellular carcinoma, nasopharyngeal carcinoma, multiple myeloma, non-small cell lung cancer, and prostate cancer, was closely related to the proliferation, metastasis, adhesion, and angiogenesis of tumor cells. These results suggest that ITGA9 plays an important role in the occurrence and development of tumors. The integrin subunit ITGA9 may serve as a biomarker for the diagnosis of tumors and a potential therapeutic target for anti-tumor therapies.

The Regulatory Role of Both MBNL1 and MBNL1-AS1 in Several Common Cancers.

BACKGROUND: Muscle blind-like-proteins (MBNL) are a class of tissue-specific RNA metabolism regulators that control pre-messenger RNA-splicing. Inactivation of MBNL can lead to myotonic dystrophy in adults. MBNL is mainly expressed in skeletal muscle, neuron tissue, thymus, liver, and kidney and plays an important role in the ultimate differentiation of muscle cells and neurons. MBNL1 is a member of the MBNL protein family. The inactivation of MBNL1 protein is particularly important in the development of myotonic dystrophy and can lead to cataract formation, abnormal muscle relaxation, cardiac and neurological dysfunction, etc. The induction of MBNL1 in tumors is known to significantly inhibit tumor progression and thus significantly prolong survival. MBNL1 antisense protein MBNL1-AS1 also plays an important role in tumor migration and development. OBJECTIVE: This review reveals the role of MBNL1 and MBNL1-AS1 in the complex pathogenesis of many tumors, which provide a new target for the treatment of tumors. METHODS: Correlated research are systematically retrieved via PubMed. In this review, the role of MBNL1 and MBNL1- AS1 were analyzed. RESULTS: MBNL1 is down-regulated in breast cancer, leukemia, stomach cancer, esophageal cancer, glioma, and Huntington's disease. The function of inhibiting tumor cell metastasis decreased. It is up-regulated in cervical cancer and colorectal cancer, which can promote the development of tumor cells. Antisense protein MBNL1- AS1 can inhibit tumor cell proliferation and metastasis in colorectal cancer, non-small cell lung cancer, and gastric cancer. CONCLUSION: MBNL1 is an important regulator of tumor metastasis and growth, which exhibits a promising therapeutic target and can be further explored.
