Long noncoding RNA H19 (H19) is an imprinting gene with only maternal expression that is involved in regulating different processes in various types of cells. Previous studies have shown that abnormal H19 expression is involved in many pathological processes, such as cancer, mainly through sponging miRNAs, interacting with proteins, or regulating epigenetic modifications. Accumulating evidence has shown that several oncogenic signaling pathways lead to carcinogenesis. Recently, the regulatory relationship between H19 and oncogenic signaling pathways in various types of cancer has been of great interest to many researchers. In this review, we discussed the key roles of H19 in cancer development and progression via its regulatory function in several oncogenic signaling pathways, such as PI3K/Akt, canonical Wnt/β-catenin, canonical NF-κB, MAPK, JAK/STAT and apoptosis. These oncogenic signaling pathways regulated by H19 are involved in cell proliferation, proliferation, migration and invasion, angiogenesis, and apoptosis of various cancer cells. This review suggests that H19 may be a novel therapeutic target for cancers treatment by regulating oncogenic signaling pathways.

Oncogenic Signaling Pathways

AbstractThe m6A RNA methylation is the most prevalent internal modification in mammalian mRNAs which plays critical biological roles by regulating vital cellular processes. Dysregulations of the m6A modification due to aberrant expression of its regulatory proteins are frequently observed in many pathological conditions, particularly in cancer. Normal cells undergo malignant transformation via activation or modulation of different oncogenic signaling pathways through complex mechanisms. Accumulating evidence showing regulation of oncogenic signaling pathways at the epitranscriptomic level has added an extra layer of the complexity. In particular, recent studies demonstrated that, in many types of cancers various oncogenic signaling pathways are modulated by the m6A modification in the target mRNAs as well as noncoding RNA transcripts. m6A modifications in these RNA molecules control their fate and metabolism by regulating their stability, translation or subcellular localizations. In this review we discussed recent exciting studies on oncogenic signaling pathways that are modulated by the m6A RNA modification and/or their regulators in cancer and provided perspectives for further studies. The regulation of oncogenic signaling pathways by the m6A modification and its regulators also render them as potential druggable targets for the treatment of cancer.

Abstract Background Cervical cancer (CC) is the fourth leading cause of cancer-associated death in women worldwide. Recently, long noncoding RNA (lncRNA) prostate cancer gene expression marker 1 (PCGEM1) has been demonstrated to involve in the initiation and progression of human cancers. However, to date, the clinical and functional significance of PCGEM1 expression in CC progression remains unknown. Methods qRT-PCR was performed to investigate PCGEM1 expression levels in CC tissues and cell lines. The effect of PCGEM1 on CC cells was assessed by gain- and loss-of-function assays. MS2-binding sequences-MS2-binding protein-based RIP assay (MS2-RIP), RNA pull-down and Luciferase reporter assays were performed to investigate the interaction between PCGEM1 and miR-182. The association between miR-182 and F-box and WD repeat domain containing 11 (FBXW11) was verified by luciferase reporter assay. The effect of PCGEM1 on the NF-κB and β-catenin/TCF signaling pathways was determined by luciferase reporter assay. Results Our present study showed that PCGEM1 was significantly upregulated in CC tissues and cell lines. Overexpression of PCGEM1 was correlated with advanced International Federation of Gynecology and Obstetrics (FIGO) stage, lymph node, distant metastasis and poor prognosis in CC patients. Functionally, PCGEM1 promoted cell proliferation, cell cycle progression, migration and invasion, while suppressed cell apoptosis in CC cells. Further mechanistic investigation revealed that PCGEM1 associated with miR-182 and suppressed its expression. PCGEM1 could act as a competing endogenous (ceRNA) of oncogene F-box and WD repeat domain containing 11 (FBXW11) for miR-182 in CC cells. Additionally, PCGEM1 was capable to activate the NF-κB and β-catenin/TCF signaling pathways, which was reversed by inhibition of FBXW11. Conclusion In conclusion, our findings demonstrated that PCGEM1-miR-182-FBXW11 axis play an important role in CC progression, and indicated a promising therapeutic target for CC patients.

Background: A number of studies have proposed that lncRNA XIST plays a role in the development and chemosensitivity of NSCLC. Besides, XIST may become a potential therapeutic target for NSCLC patients. The aim of this review is to reveal the biological functions and exact mechanisms of XIST in NSCLC. Methods: In this review, relevant researches involving in the relationship between XIST and NSCLC are collected through systematic retrieval of PubMed Results: XIST is an oncogene in NSCLC and is abnormally upregulated in NSCLC tissues. Considerable evidence has shown that XIST exerts a critical role in the proliferation, invasion, migration, apoptosis and chemosensitivity of NSCLC cells. XIST mainly functions as a ceRNA in NSCLC process, while XIST also functions at transcriptional levels. Conclusion: LncRNA XIST has potential to become a novel biomolecular marker of NSCLC and a therapeutic target for NSCLC.

: Central dogma of molecular biology has remained cornerstone of classical molecular biology but serendipitous discovery of microRNAs (miRNAs) in nematodes paradigmatically shifted our current understanding of the intricate mech-anisms which occur during transitions from transcription to translation. Discovery of miRNA captured tremendous attention and appreciation and we had witnessed an explosion in the field of non-coding RNAs. Ground-breaking discoveries in the field of non-coding RNAs have helped in better characterization of microRNAs and long non-coding RNAs (LncRNAs). There is an ever-increasing list of miRNA targets which are regulated by MALAT1 to stimulate or repress expression of tar-get genes. However, in this review our main focus is to summarize mechanistic insights related to MALAT1-mediated regu-lation of oncogenic signaling pathways. We have discussed how MALAT1 modulated TGF/SMAD and Hippo pathways in various cancers. We have also comprehensively summarized how JAK/STAT and Wnt/β-catenin pathways stimulated MALAT1 expression and consequentially how MALAT1 potentiated these signaling cascades to promote cancer. MALAT1 research has undergone substantial broadening however, there is still a need to identify additional mechanisms. MALAT1 is involved in multi-layered regulation of multiple transduction cascades and detailed analysis of different pathways will be helpful in getting a step closer to individualized medicine.
