Abstract
BACKGROUND The multi-drug resistance is an inherent weakness in the chemotherapeutics of non-small cell lung cancer occurring frequently all over the world. Clinically, ginseng and Chinese medicinal prescriptions including ginseng usually used as anti-tumor adjuncts due to its characteristic of qi-invigorating, which could improve the curative effect of chemotherapy drugs and reduce their toxic side effects. Triterpenoid saponins are the crucial active ingredients in Panax ginseng, and Ginsenoside Rb1 is of the highest quantities. However, the research on the tumor drug-resistance reversal effect and mechanism of ginsenoside Rb1 is still not clear. PURPOSE This study aimed to systematically estimate the reversal activity of Ginsenoside Rb1 on cisplatin-insensitivity of A549/DDP cells and to reveal its prospective molecular mechanism. METHODS MTT assay were conducted to evaluate the reversal activity on cisplatin-insensitivity of A549/DDP cells of Ginsenoside Rb1in vitro, and the behavior was also studied by establishing a subcutaneous transplanted tumor model of A549/DDP in BALB/c-nu mice. In addition, P-gp ATPase activity assay, cisplatin accumulation assay, Annexin V-FITC apoptosis assay, real-time qPCR analysis and western blotting analysis were used to clarify the potential mechanism. RESULTS Ginsenoside Rb1 could effectively reverse the cisplatin-resistance of A549/DDP in vitro and vivo. And after the co-treatment of Ginsenoside Rb1 plus cisplatin, the accumulation of cisplatin increased in A549/DDP cells, which was accompanied with the down-regulation of the mRNA and protein expression levels of ABCB1, SHH, PTCH1 and GLI2. Besides, the apoptosis-inducing ability of cisplatin improved by the relative regulation on the protein expression level of Bax and Bcl-2. Far more importantly, the changes of CYP3A4 mRNA and protein levels were not significant. CONCLUSION Ginsenoside Rb1 could increase the concentration of intracellular cisplatin and improve the insensitivity for cisplatin on A549/DDP cells. Even better, there was perhaps no unpredictable CYP3A4-mediated pharmacokinetic interactions after the combination of Ginsenoside Rb1 plus cisplatin. Ginsenoside Rb1 was a probable reversal agent for the cisplatin-insensitivity of A549/DDP cells, with a bifunction of inhibiting the efflux of two drug pumps (P-gp and PTCH1) by targeting ABCB1 and Hedgehog (Hh) pathway. In general, this research laid the groundwork for the development of a new reversal agent for the cisplatin-insensitivity of NSCLC.

Abstract
Cucurbitacin B (CuB) is a class of tetracyclic triterpenoids isolated from Cucurbitaceae with a wide range of anti-inflammatory and anti-tumor activities, mainly used in hepatitis and hepatocellular carcinoma, while there is relatively little research and application of this drug for lung cancer. In this study, CuB was administered on A549/DDP cells to observe how it affected the cells and their mechanism of action. CuB demonstrated good anti-tumor activity against A549/DDP cells in a dose-dependent manner and caused changes in the hedgehog (Hh) pathway. The results showed that CuB greatly inhibits the proliferation and the invasion of A549/DDP cells, and promoted apoptosis of A549/DDP cells. Meanwhile, it changed the expression of p53-related genes at the RNA and protein level. In conclusion, this experiment provides a theoretical basis for new applications of CuB and new thoughts on the mechanism of its anti-tumor activity, and provides a direction for deep research.

Abstract
Most human malignant neoplasms show loss of primary cilia (PC). However, PC are known to be retained and involved in tumorigenesis in some types of neoplasms. The PC status in lung carcinomas remains largely uninvestigated. In this study, we comprehensively assessed the PC status in lung carcinomas. A total of 492 lung carcinomas, consisting of adenocarcinomas (ACs) (n = 319), squamous cell carcinomas (SCCs) (n = 152), and small cell lung carcinomas (SCLCs) (n = 21), were examined by immunohistochemical analysis using an antibody against ARL13B, a marker of PC. The PC-positive rate was markedly higher in SCLCs (81.0%) than in ACs (1.6%) and SCCs (7.9%). We subsequently performed analyses to characterize the PC-positive lung carcinomas further. PC-positive lung carcinomas were more numerous and had longer PC than normal cells. The presence of PC in these cells was not associated with the phase of the cell cycle. We also found that the PC were retained even in metastases from PC-positive lung carcinomas. Furthermore, the hedgehog signaling pathway was activated in PC-positive lung carcinomas. Because ARL13B immunohistochemistry of lung carcinoids (n = 10) also showed a statistically significantly lower rate (10.0%) of PC positivity than SCLCs, we searched for a gene(s) that might be upregulated in PC-positive SCLCs compared with lung carcinoids, but not in PC-negative carcinomas. This search, and further cell culture experiments, identified HYLS1 as a gene possessing the ability to regulate ciliogenesis in PC-positive lung carcinomas. In conclusion, our findings indicate that PC are frequently present in SCLCs but not in non-SCLCs (ACs and SCCs) or lung carcinoids, and their PC exhibit various specific pathobiological characteristics. This suggests an important link between lung carcinogenesis and PC.

Abstract
The present study aimed to assess the anticancer cell and anticancer stem cell (CSC) effects of GANT61, and its regulatory influence on the Wnt/β-catenin and Notch signalling pathways in colorectal cancer (CRC). HT-29 and HCT-116 cells were treated with 0, 2.5, 5, 10, 20 or 40 µM GANT61, after which relative cell viability and the expression of Gli1, β-catenin and Notch1, as well as the percentage of CD133+ cells, were detected. Subsequently, HT-29/HCT-116 cells and CSCs were treated with 20 µM GANT61, 10 mM of the Wnt/β-catenin pathway agonist HLY78, and 30 mM of the Notch pathway agonist JAG1 (alone or in combination), which was followed by the assessment of cell viability and apoptosis. In both cell lines, GANT61 reduced relative cell viability in a time- and dose-dependent manner, inhibited Gli1, β-catenin and Notch1 expression, and decreased the percentage of CD133+ cells in a dose-dependent manner. Furthermore, HLY78 and JAG1 were both found to improve the relative viability, while downregulating the apoptosis of untreated and GANT61-treated HT-29 and HCT-116 cells. Moreover, Wnt/β-catenin and Notch signalling pathway activity were upregulated in CSCs isolated from HT-29 and HCT-116 cells, compared with the associated control groups. GANT61 also reduced the viability of HT-29 and HCT-116 cells and increased apoptosis, whereas HLY78 and JAG1 treatment resulted in the opposite effect. Moreover, both HLY78 and JAG1 attenuated the effects of GANT61 on cellular viability and apoptosis. In conclusion, GANT61 was found to effectively eliminate cancer cells and CSCs by blocking the Wnt/β-catenin and Notch signalling pathways in CRC.

Abstract
It is being brought to light that smoothened (SMO)-independent non-canonical Hedgehog signaling is associated with the pathogenesis of various cancers. Ursolic acid (UA), a pentacyclic triterpenoid present in many medicinal herbs, manifests potent effectiveness against multiple malignancies including colorectal cancer (CRC). In our previous study, UA was found to protect against CRC in vitro by suppression of canonical Hedgehog signaling cascade. Here, the influence of UA on SMO-independent non-canonical Hedgehog signaling in CRC was investigated in the present study, which demonstrated that UA hampered the proliferation and migration, induced the apoptosis of HCT-116hSMO- cells with SMO gene knockdown, accompanied by the augmented expression of the suppressor of fused (SUFU), and lessened levels of MYC (c-Myc), glioma-associated oncogene (GLI1) and Sonic Hedgehog (SHH), and lowered phosphorylation of protein kinase B (PKB, AKT), suggesting that UA diminished non-canonical Hedgehog signal transduction in CRC. In HCT-116hSMO- xenograft tumor, UA ameliorated the symptoms, impeded the growth and caused the apoptosis of CRC, with heightened SUFU expression, and abated levels of MYC, GLI1, and SHH, and mitigated phosphorylation of AKT, indicating that UA down-regulated non-canonical Hedgehog signaling cascade in CRC. Taken together, UA may alleviate CRC by suppressing AKT signaling-dependent activation of SMO-independent non-canonical Hedgehog pathway.

Abstract
The development of the embryonic lung demands complex endodermal–mesodermal interactions, which are regulated by a variety of signaling proteins. Hedgehog (Hh) signaling is vital for lung development. It plays a key regulatory role during several morphogenic mechanisms, such as cell growth, differentiation, migration, and persistence of cells. On the other hand, abnormal expression or loss of regulation of Hh signaling leads to airway asthmatic remodeling, which is characterized by cellular matrix modification in the respiratory system, goblet cell hyperplasia, deposition of collagen, epithelial cell apoptosis, proliferation, and activation of fibroblasts. Hh also targets some of the pathogens and seems to have a significant function in tissue repairment and immune-related disorders. Similarly, aberrant Hh signaling expression is critically associated with the etiology of a variety of other airway lung diseases, mainly, bronchial or tissue fibrosis, lung cancer, and pulmonary arterial hypertension, suggesting that controlled regulation of Hh signaling is crucial to retain healthy lung functioning. Moreover, shreds of evidence imply that the Hh signaling pathway links to lung organogenesis and asthmatic airway remodeling. Here, we compiled all up-to-date investigations linked with the role of Hh signaling in the development of lungs as well as the attribution of Hh signaling in impairment of lung expansion, airway remodeling, and immune response. In addition, we included all current investigational and therapeutic approaches to treat airway asthmatic remodeling and immune system pathway diseases.

Abstract
GLI1 is one of three GLI family transcription factors that mediate Sonic Hedgehog signaling, which plays a role in development and cell differentiation. GLI1 forms a positive feedback loop with GLI2 and likely with itself. To determine the impact of GLI1 and its intronic regulatory locus on this transcriptional loop and human stem cell differentiation, we deleted the region containing six GLI binding sites in the human GLI1 intron using CRISPR/Cas9 editing to produce H1 human embryonic stem cell (hESC) GLI1‐edited clones. Editing out this intronic region, without removing the entire GLI1 gene, allowed us to study the effects of this highly complex region, which binds transcription factors in a variety of cells. The roles of GLI1 in human ESC differentiation were investigated by comparing RNA sequencing, quantitative‐real time PCR (q‐rtPCR), and functional assays. Editing this region resulted in GLI1 transcriptional knockdown, delayed neural commitment, and inhibition of endodermal and mesodermal differentiation during spontaneous and directed differentiation experiments. We found a delay in the onset of early osteogenic markers, a reduction in the hematopoietic potential to form granulocyte units, and a decrease in cancer‐related gene expression. Furthermore, inhibition of GLI1 via antagonist GANT‐61 had similar in vitro effects. These results indicate that the GLI1 intronic region is critical for the feedback loop and that GLI1 has lineage‐specific effects on hESC differentiation. Our work is the first study to document the extent of GLI1 abrogation on early stages of human development and to show that GLI1 transcription can be altered in a therapeutically useful way.

Abstract
Lung cancer is the leading cause of cancer-associated death worldwide. In recent years, the advancement of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) targeted therapies has provided clinical benefits for lung cancer patients with EGFR mutations. The response to EGFR-TKI varies in patients with lung cancer, and resistance typically develops during the course of the treatment. Therefore, understanding biomarkers which can predict resistance to EGFR-TKI is important. Overexpression of GLI causes activation of the Hedgehog (Hh) signaling pathway and plays a critical role in oncogenesis in numerous types of cancer. In the present study, the role of GLI1 in erlotinib resistance was investigated. GLI1 mRNA and protein expression levels were determined using reverse transcription-quantitative PCR and immunohistochemistry (IHC) in lung cancer cell lines and tumor specimens, respectively. GLI1 mRNA expression levels were found to be positively correlated with the IC50 of erlotinib in 15 non-small cell lung cancer (NSCLC) cell lines. The downregulation of GLI1 using siRNA sensitized lung cancer cells to the erlotinib treatment, whereas the overexpression of GLI1 increased the survival of lung cancer cells in the presence of erlotinib, indicating that Hh/GLI activation may play a critical role in the development of TKI resistance in lung cancer. Combined treatment with erlotinib and a GLI1 inhibitor reduced the cell viability synergistically. A retrospective study of patients with NSCLC treated with erlotinib revealed that those with a high IHC score for GLI1 protein expression had a poorer prognosis. These results indicated that GLI1 is a key regulator for TKI sensitivity, and patients with lung cancer may benefit from the combined treatment of TKI and GLI1 inhibitor.

Abstract
Aberrant activation of the Hedgehog (Hh)/Gli pathway contributes to the tumorigenesis of several human cancers, including ovarian cancers. We investigated the function of SMO on cell growth, drug resistance, and invasive ability in A2780/DDP cells. Moreover, we also tested the levels of the downstream target genes of the Hh/Gli pathway in SMO short hairpin RNA (shRNA) lentivirus-infected A2780/DDP cells. Western blot analysis results revealed that the Hh/Gli pathway was activated in cisplatin-resistant A2780/DDP cells. After infection by SMO shRNA lentivirus, the colony formation rate and invasive rate of cisplatin-resistant A2780/DDP cells were decreased. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay showed that upon transfection with SMO shRNA, cell growth was decreased and drug sensitivity to cisplatin was upregulated. Moreover, interference with SMO decreased the expression of MMP-2, MMP-9, VEGF, and Snail in cisplatin-resistant cells. Thus, the Hh/Gli signaling pathway was aberrantly activated in A2780/DDP cells. The colony formation rate and invasive rate were decreased in SMO shRNA lentivirus-infected A2780/DDP cells. All results showed that inhibiting Hh/Gli signaling may negatively regulate the proliferation, invasion, and metastasis of cisplatin-resistant A2780/DDP cells, as well as increase the sensitivity of A2780/DDP to the chemotherapeutic drug of cisplatin.

Abstract
Pulmonary hypertension (PH) is a clinically common malignant cardiovascular disease. Pyroptosis is a new form of inflammatory cell death that is involved in many disease processes. Glioma-associated oncogene family zinc finger 1 (GLI1) is a transcriptional activator that participates in many diseases, but its role has never been explored in inducing pyroptosis and the progress of PH. In this study, we used an animal model and cell molecular biology to determine the effect of GLI1 on chronic hypoxia-mediated PH progression and pulmonary artery smooth muscle cell (PASMC) pyroptosis. The major findings of the present study are as follows: Hypoxia induced aberrant expression of GLI1. The inhibition of GLI1 attenuated hypoxia-induced PH and PASMC pyroptosis. Meanwhile, GLI1 enhanced apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) expression by binding with its promoter. GLI1 may promote PASMC pyroptosis through ASC to affect the progression of PH. These findings may identify novel targets for molecular therapy of PH.

Abstract
Aberrant expression of long non-coding RNAs (lncRNAs) has been observed in hepatocellular carcinoma (HCC) and confirmed to participate in the initiation and progression of HCC. In the present study, we identified a novel functional lncRNA, hedgehog-interacting protein antisense RNA 1 (HHIP-AS1). The expression levels of HHIP-AS1 were significantly decreased in HCC tissues. Downregulation of HHIP-AS1 expression correlated with larger tumor size, metastasis, and advanced TNM stage, and also predicted worse overall survival rate of HCC patients. Through performing overexpression and knockdown experiments, the biological function of HHIP-AS1 was identified to suppress HCC cell proliferation, migration and invasion, while promote apoptosis. Further investigation showed that HHIP-AS1 interacted with and positively regulated the stability of HHIP mRNA in a HuR-dependent manner. HHIP-AS1 exerted its suppressive effects through HHIP. Taken together, our findings demonstrate that HHIP-AS1 represses HCC progression by promoting HHIP expression, and indicate that the use of HHIP-AS1 may offer a promising treatment for HCC patients.

Abstract
The hedgehog (HH) signaling pathway is central to the regulation of bone development and homeostasis. HH signaling is not only involved in osteoblast differentiation from bone marrow mesenchymal stem cells (BM-MSCs), but also acts upstream within osteoblasts via the OPG/RANK/RANKL axis to control the expression of RANKL. HH signaling has been found to up-regulate parathyroid hormone related protein (PTHrP) expression in osteoblasts, which in turn activates its downstream targets nuclear factor of activated T cells (NFAT) and cAMP responsive element binding protein (CREB), and as a result CREB and NFAT cooperatively increase RANKL expression and osteoclastogenesis. Osteoblasts must remain in balance with osteoclasts in order to avoid excessive bone formation or resorption, thereby maintaining bone homeostasis. This review systemically summarizes the mechanisms whereby HH signaling induces osteoblast development and controls RANKL expression through PTHrP in osteoblasts. Proper targeting of HH signaling may offer a therapeutic option for treating bone homeostasis disorders.
