Abstract Background The decoction of Astragalus membranaceus (Huangqi) and Rhizoma curcumae (Ezhu) has been reported as a potential antitumor agent for colorectal cancer (CRC) in experimental and clinical studies, but its underlying mechanism is still unclear. Methods The current research aims to explore the potential of Astragalus membranaceus (Huangqi) and Rhizoma curcumae (Ezhu) decoction (AR decoction) in the treatment of CRC and explore the underlying mechanism. SW620 cells were transient transfection to overexpress or knock down wnt 5 or β-Catenin. Astragalus membranaceus (Huangqi) and Rhizoma curcumae (Ezhu) -containing serum (AR-CS) was used to interfere with SW620 cells. Additional AR-CS, Wnt5 inhibitor (IWP-4), and β-Catenin inhibitor (JW55) were used to intervene in SW620 cells. Furthermore, subcutaneously injection of SW620 cells into the right flank of nude mice replicated xenograft mice, which were treated with AR decoction for 21 days. Results AR-CS significantly reduced the mRNA and protein expression levels of Wnt5, β-Catenin, ARF6, and N-Cadherin in SW620 cells, while inhibiting the proliferation and migration of SW620 cells. In cells overexpressing Wnt5 or β-Catenin, these effects of AR-CS were significantly suppressed. On the contrary, the inhibitory effect of AR-CS on the mRNA and protein levels of ARF6 and N-Cadherin and cell proliferation and migration of SW620 was enhanced, when Wnt5 or β-Catenin were knocked down or suppressed by the inhibitors. Moreover, in the mouse model of xenograft tumors, AR decoction not only reduced the tumor volume and inhibited the mRNA levels and protein levels of Wnt5, β-Catenin, ARF6, and N-Cadherin in the tumor, but also inhibit the protein levels of LRP5, LRP6, TCF-4, and LEF1.The histopathology of mice also showed increased apoptosis in tumor tissues, and AR decoction treatment did not cause pathological damage to the kidney and liver. Conclusions Our results provide evidence that AR decoction inhibits Wnt5/β-catenin signaling and inhibits the development of CRC, which is a promising traditional medicine in the clinical treatment of CRC.

Colorectal cancer (CRC) is one of the most frequent malignant neoplasms worldwide, and the effect of treatments is limited. Fibroblast growth factor 1 (FGF1) has been involved in a wide variety of several malignant diseases and takes part in the tumorigenesis of CRC. However, the function and mechanism of FGF1 in CRC remains elusive. In this study, the results indicated that FGF1 is elevated in CRC tissues and linked with poor prognosis (P < 0.001). In subgroup analysis of FGF1 in CRC, regardless of any clinic-factors except gender, high level FGF1 expression was associated with markedly shorter survival (P < 0.05). In addition, the expression of p-S6K1 and FGF1 was not associated in normal tissue (P = 0.781), but their expression was closely related in tumor tissue (P = 0.010). The oncogenic role of FGF1 was determined using in vitro and in vivo functional assays. FGF1 depletion inhibited the proliferation and migration of CRC cells in vitro and vivo. FGF1 was also significantly correlated with mTOR-S6K1 pathway on the gene and protein levels (P < 0.05). In conclusion, FGF1 acts as a tumor activator in CRC, and against FGF1 may provide a new visual field on treating CRC, especially for mTORC1-targeted resistant patients.

Abstract Prior studies have shown that apolipoprotein M (APOM) is involved in the development of some cancers. Here we investigated the effects of APOM on larynx cancer (LC). 20 patients with vocal cord polyps and 18 patients with LC were included in this study. The protein and mRNA levels of the samples were analysed using the Wes-ProteinSimple system (or traditional Western blot) and PCR technology, respectively. APOM protein level in cancer tissues was lower than that in paracarcinomatous (P = 0.0003) and polyp tissues (P < 0.0001). APOM overexpression significantly inhibited TU686 cell proliferation (P < 0.0001) and migration (P < 0.01), and increased expression of vitamin D receptor (VDR, P < 0.0001) as well as nuclear factor erythroid 2-like 3 (NFE2L3, P = 0.0215). In addition, matrix metalloproteinase-10 (MMP-10) mRNA level was significantly reduced in the APOM overexpression group (P = 0.0077). However, Western blot analysis showed that APOM overexpression did not change VDR, NFE2L3 and MMP-10 protein levels (P > 0.05). In summary, APOM inhibits the proliferation and migration of LC cells, but may not be related to VDR, NFE2L3 and MMP-10, which needs further study.

Objective. We have identified a gene YOD1 encoding deubiquitinating enzyme (DUB) responsible for nonsyndromic cleft lip with or without cleft palate (NSCL/P). We aimed to determine the effects of YOD1 RNA interference (RNAi) on cell proliferation and migration, playing an important role in lip and palate formation, and to clarify whether the mechanisms involved TGF-β3 signaling associated with NSCL/P. Methods. RNAi was applied to construct vectors expressing YOD1 small interference RNAs (siRNAs). The vectors were transfected into the human oral keratinocytes (HOK) cells. The cell proliferation and migration were evaluated by the cell counting kit-8 (CCK-8) assay and wound healing assay, respectively. The mRNA levels were detected by quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR). The protein levels were investigated by western blotting. Results. The proliferation of YOD1 siRNA-transfected HOK cells was remarkably inhibited. The migration rate was significantly decreased in the YOD1 siRNA-transfected HOK cells. The TGF-β3 mRNA and protein levels were decreased significantly by siRNA-mediated knockdown of YOD1. YOD1 RNAi reduced the phosphor-Smad2/3 levels significantly. Conclusions. YOD1 RNAi may inhibit cell proliferation and migration associated with the pathogenesis of NSCL/P through TGF-β3 signaling. The study indicates a novel role of YOD1 in regulating TGF-β3 signaling to affect cell proliferation and migration resulting in NSCL/P.

High human telomerase reverse transcriptase (hTERT) expression is related to severe Colorectal Cancer (CRC) progression and negatively related to CRC patient survival. Previous studies have revealed that hTERT can reduce cancer cellular reactive oxygen species (ROS) levels and accelerate cancer progression; however, the mechanism remains poorly understood. NFE2-related factor 2 (NRF2) is a molecule that plays a significant role in regulating cellular ROS homeostasis, but whether there is a correlation between hTERT and NRF2 remains unclear. Here, we showed that hTERT increases CRC proliferation and migration by inducing NRF2 upregulation. We further found that hTERT increases NRF2 expression at both the mRNA and protein levels. Our data also revealed that hTERT primarily upregulates NRF2 by increasing NRF2 promoter activity rather than by regulating NRF2 mRNA or protein stability. Using DNA pull-down/MS analysis, we found that hTERT can recruit YBX1 to upregulate NRF2 promoter activity. We also found that hTERT/YBX1 may localize to the P2 region of the NRF2 promoter. Taken together, our results demonstrate that hTERT facilitates CRC proliferation and migration by upregulating NRF2 expression through the recruitment of the transcription factor YBX1 to activate the NRF2 promoter. These results provide a new theoretical basis for CRC treatment.

Abstract Background The lncRNA colorectal neoplasia differentially expressed (lncRNA CRNDE) is commonly over-expressed in different human cancers and involved in different biological functions. Paclitaxel(PTX) is a tricyclic diterpenoid compound which often used as a natural anticancer drugs in cancer treatments. Although there have many research reports about the mechanisms of LncRNA involved in PTX treatment, there are no any research about lncRNA CRNDE and PTX resistance in colorectal cancer. The purpose of this study is to investigate the mechanisims of LncRNA CRNDE involving PTX resistance in colorectal cancer. Results We constructed lncRNA CRNDE over-expression vector and transfected it into SW620 cell. CCK8, Transwell experiments proved that over-expression of lnc CRNDE increased SW620 cells proliferation and invasion, while the si-CRNDE group was significantly decreased. over-expression CRNDE can significantly up-regulate β-catenin, c-myc, APC and Axin2 expression and affect the expression of cyclinD1 and CDK4 after treated with PTX. Conclusion lncRNA CRNDE promotes CRCs proliferation, invasion and migration. Over-expression of LncRNA CRNDE enhanced the reisitance of CRC to PTX through inhibition of Wnt/ β-catenin signaling pathway.
