Abstract
Cancer is a multifactorial pathological condition characterized by uncontrolled cellular proliferation, genomic instability, and evasion of regulatory mechanisms. It arises from the accumulation of genetic mutations confer selective growth advantages, leading to malignant transformation and tumor formation. The intricate interplay between LncRNAs and the Hedgehog pathway has emerged as a captivating frontier in cancer research. The Hedgehog pathway, known for its fundamental roles in embryonic development and tissue homeostasis, is frequently dysregulated in various cancers, contributing to aberrant cellular proliferation, survival, and differentiation. The Hh pathway is crucial in organizing growth and maturation processes in multicellular organisms. It plays a pivotal role in the initiation of tumors as well as in conferring resistance to conventional therapeutic approaches. The crosstalk among the Hh pathway and lncRNAs affects the expression of Hh signaling components through various transcriptional and post-transcriptional processes. Numerous pathogenic processes, including both non-malignant and malignant illnesses, have been identified to be induced by this interaction. The dysregulation of lncRNAs has been associated with the activation or inhibition of the Hh pathway, making it a potential therapeutic target against tumorigenesis. Insights into the functional significance of LncRNAs in Hedgehog pathway modulation provide promising avenues for diagnostic and therapeutic interventions. The dysregulation of LncRNAs in various cancer types underscores their potential as biomarkers for early detection and prognostication. Additionally, targeting LncRNAs associated with the Hedgehog pathway presents an innovative strategy for developing precision therapeutics to restore pathway homeostasis and impede cancer progression. This review aims to elucidate the complex regulatory network orchestrated by LncRNAs, unravelling their pivotal roles in modulating the Hedgehog pathway and influencing cancer progression.

Differential association of hedgehog pathway in development of cervical carcinoma and its chemo-tolerance. Pathol Res Pract 2023; 248:154696. [PMID: 37516000 DOI: 10.1016/j.prp.2023.154696] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 07/14/2023] [Accepted: 07/14/2023] [Indexed: 07/31/2023]
Abstract
Cervical carcinoma (CACX) is still a dreadful threat to women in developing countries. Available conventional chemo-radiation therapies are not sufficient to restrict the disease recurrence. To unravel the mechanism of the disease recurrence, alteration of hedgehog self-renewal pathway was evaluated during development of CACX and in chemo-tolerance of the tumor. We have analyzed the alterations (expression/methylation/deletion) of some key regulatory genes (HHIP/SUFU/SHH/ SMO/GLI1) of hedgehog self-renewal pathway in cervical lesions at different clinical stages and compared with different datasets, followed by their clinico-pathological correlations. The changes in expression/methylation of the genes were then evaluated in two CACX cell lines (SiHa/HeLa) after treatment with chemotherapeutic drug cisplatin at different concentrations. Down regulation (mRNA/protein) of the antagonists HHIP and SUFU due to promoter methylation and/or deletion along with upregulation (protein) of agonists SHH, SMO and GLI1 was seen in early invasive lesions and subsequent clinical stages. Reduced protein expression of HHIP and SUFU showed significant association with high/intermediate expression of agonists SHH, SMO, GLI1 in the tumors and also poor prognosis of the patients. It was evident that cisplatin could restrict the growth of HeLa and SiHa cells through significant upregulation of antagonists HHIP and SUFU due to their promoter hypomethylation and down regulation of SHH in a concentration dependent manner without any significant changes in expression of SMO and GLI1, leading to the tumor cells in a dormant state. Thus, interplay of the agonists and antagonists has important role in activation of hedgehog pathway during development of CACX, whereas inactivation of the pathway due to upregulation of the antagonists is an important phenomenon in chemo-tolerance of the tumor. This suggests importance of epigenetic modification in chemo-resistance of CACX.

The role of Hedgehog and Notch signaling pathway in cancer. MOLECULAR BIOMEDICINE 2022; 3:44. [PMID: 36517618 PMCID: PMC9751255 DOI: 10.1186/s43556-022-00099-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 10/25/2022] [Indexed: 12/23/2022] Open
Abstract
Notch and Hedgehog signaling are involved in cancer biology and pathology, including the maintenance of tumor cell proliferation, cancer stem-like cells, and the tumor microenvironment. Given the complexity of Notch signaling in tumors, its role as both a tumor promoter and suppressor, and the crosstalk between pathways, the goal of developing clinically safe, effective, tumor-specific Notch-targeted drugs has remained intractable. Drugs developed against the Hedgehog signaling pathway have affirmed definitive therapeutic effects in basal cell carcinoma; however, in some contexts, the challenges of tumor resistance and recurrence leap to the forefront. The efficacy is very limited for other tumor types. In recent years, we have witnessed an exponential increase in the investigation and recognition of the critical roles of the Notch and Hedgehog signaling pathways in cancers, and the crosstalk between these pathways has vast space and value to explore. A series of clinical trials targeting signaling have been launched continually. In this review, we introduce current advances in the understanding of Notch and Hedgehog signaling and the crosstalk between pathways in specific tumor cell populations and microenvironments. Moreover, we also discuss the potential of targeting Notch and Hedgehog for cancer therapy, intending to promote the leap from bench to bedside.

Abstract
Hedgehog (HH), a conserved signaling pathway, is involved in embryo development, organogenesis, and other biological functions. Dysregulation and abnormal activation of HH are involved in tumorigenesis and tumor progression. With the emergence of interest in noncoding RNAs, studies on their involvement in abnormal regulation of biological processes in tumors have been published one after another. In this review, we focus on the crosstalk between noncoding RNAs and the HH pathway in tumors and elaborate the mechanisms by which long noncoding RNAs and microRNAs regulate or are regulated by HH signaling in cancer. We also discuss the interaction between noncoding RNAs and the HH pathway from the perspective of cancer hallmarks, presenting this complex network as concisely as possible and organizing ideas for cancer diagnosis and treatment.
