Study on the mechanism of BGN in progression and metastasis of ccRCC

ABSTRACT: Based on multiple public databases, we investigated the expression level of BGN in ccRCC, its clinical significance, and its association with immune cells. Real-time fluorescence quantitative PCR was employed to validate BGN expression in tumor and adjacent normal tissues. Differential gene analysis, GO-KEGG analysis, and GSEA analysis were performed by RNA sequencing to elucidate the underlying signaling pathways. BGN knockdown cells were generated through lentiviral transfection to examine the impact of BGN on ccRCC. Cell proliferation, migration, and invasion were assessed using CCK8, colony formation, wound healing, Transwell migration, and invasion assays, respectively. Results: Our findings from database analysis and polymerase chain reaction (PCR) revealed a significant upregulation of BGN expression in kidney cancer tissues compared to normal tissues. Further analysis demonstrated a correlation between high BGN expression and ccRCC progression and immune infiltration. In vitro experiments confirmed that BGN silencing effectively inhibited cell proliferation, migration, and invasion of ccRCC. Mechanistically, these effects may be mediated through the MAPK signaling pathway. Conclusion: BGN potentially plays a pivotal role in the progression and metastasis of ccRCC, possibly acting through the MAPK signaling pathway. Therefore, BGN holds promise as a potential therapeutic target for ccRCC.

BGN promotes epithelial migration in mammary gland development and breast cancer metastasis through activation of WNT signaling

Project description:This study investigates the role of Biglycan (BGN) in promoting epithelial migration during mammary gland development and breast cancer metastasis. Using in vitro and in vivo models, including a 3D organoid migration assay and single-cell RNA sequencing, we demonstrate that BGN enhances the interaction between WNT3A and FZD6, activating the WNT signaling pathway. This activation promotes epithelial cell migration and breast cancer metastasis. The findings provide new insights into breast cancer metastasis mechanisms and identify BGN as a potential therapeutic target.

KIAA1429 promotes cell proliferation by regulating MYC messenger RNA in clear cell renal cell carcinoma

Project description:KIAA1429 is an integral component of the m6A methyltransferase complex, essential for facilitating the interaction between the catalytic core components METTL3 and METTL14. However, the mechanisms by which KIAA1429 influences clear cell Renal cell carcinoma (ccRCC) remain incompletely elucidated. Analysis of the TCGA and GEO database confirmed that KIAA1429 was significantly upregulated in ccRCC samples, which correlated with poor survival. Additionally, qRT-PCR, Western Blot and IHC detection revealed significantly upregulated levels of KIAA1429 in ccRCC tissues. Moreover, multivariable Cox regression analysis showed that patients with ccRCC with high KIAA1429 expression had a poor clinical prognosis. Notably, silencing KIAA1429 significantly inhibited the proliferation, migration and invasion of ccRCC cells. Similarly, KIAA1429 knockdown also significantly inhibited the growth of ccRCC cells in nude mice. Mechanistically, KIAA1429 silencing significantly reduced the overall level of m6A in, the stability of MYC mRNA and the mRNA and protein expressions of MYC in ccRCC cells. Furthermore, RIP-qRT-PCR experiments showed that KIAA1429 could directly bind to MYC mRNA. MeRIP assay revealed that KIAA1429 knockdown resulted in a significant decrease in the m6A level of MYC mRNA in ccRCC cells. In conclusion, KIAA1429 regulates the proliferation, migration and invasion of ccRCC cells by stabilizing MYC mRNA in an m6A-dependent manner. Therefore, targeting the KIAA1429-MYC signalling pathway emerges as a potential strategy for the treatment of renal cell carcinoma.

Next generation sequencing of A375 melanoma cell line revealed a complex regulatory network when IGFBP5 overexpressed

Project description:IGFBP5, a critical regulators of insulin-like growth factors, has been reported to be involved in many kinds of carcinogenesis and cancer metastases. The role of IGFBP5 in human malignant melanoma (MM), however, remains largely unknown. In this study, we demonstrated that IGFBP5 was aberrantly expressed in human melanoma cells and cancer tissues. Overexpression of IGFBP5 dramatically inhibited the proliferation, migration and invasion of human melanoma cells, whereas knockdown of IGFBP5 by shRNA resulted in the opposite effects, enhanced the cell proliferation, migration and metastasis. In addition, IGFBP5 overexpression suppressed the growth and metastasis of melanoma xenograft tumor in vivo and IGFBP5 overexpression inhibited epithelialâmesenchymal transition (EMT) phenotype and stem cell property of tumor cell, with decreased expression of HIF1Î±, E-cadherin and stem cell markers NANOG, SOX2, OCT4, KLF4 and CD133. Moreover, IGFBP5 exhibited its growth inhibitory activity through inhibition of extracellular signal-regulated Kinase (ERK) and P38-MAPK signaling pathway. Taken together, our findings indicate that IGFBP5 acts as tumor suppressor roles in MM through the modulation of ERK1/2 and P38-MAPK signaling pathway as well as EMT procession and cell stemness, suggesting IGFBP5 as a novel target for human melanoma diagnosis and therapy. mRNA profiles of IGFBP5 over expression (OE) in A375 and A375 cell line were generated using Ion torrent

NUF2-HMGA2 axis drives cell proliferation, migration, and invasion in clear cell renal cell carcinoma

Project description:The relatively poor sensitivity of clear cell renal cell carcinoma (ccRCC) to conventional chemotherapy and radiotherapy makes its treatment challenging. The Ndc80 kinetochore complex component (NUF2) is involved in the development and progression of several cancers. However, its role in ccRCC remains unclear. In an effort to identify novel treatment targets and prognostic markers for ccRCC, we investigated the role of NUF2 in ccRCC progression. We found that the expression of NUF2 was increased in ccRCC tissues and cells, and the elevated NUF2 levels were significantly associated with worse clinicopathological parameters and shorter survival. In addition, NUF2 was an independent prognostic biomarker for ccRCC. Knocking down NUF2 expression affected the proliferation, migration, and invasion of ccRCC cells and the expression of epithelial–mesenchymal transition (EMT)-related markers. Moreover, RNA sequencing and in vitro experiments identified the oncogene high-mobility group AT-hook 2 (HMGA2) as the target factor regulated by NUF2 in ccRCC. Restoring HMGA2 levels ameliorated the inhibitory effects of NUF2 depletion on cell proliferative, migratory, and invasive capacities and recovered the expression of EMT-related markers to basal levels.These results suggest that NUF2 promotes proliferation, migration, and invasion of ccRCC cells, at least partly by regulating HMGA2, and that the NUF2-HMGA2 axis could be an ideal therapeutic target and a promising prognostic indicator for ccRCC.

piwi-interacting RNA sequencing of 2 paired clear cell renal cell carcinoma tissues and adjacent normal tissues

Project description:Clear cell renal cell carcinoma is one of the most common diagnostic tumor, with nearly one third patients diagnosed as metastatic ccRCC. Although increasing number of studies have revealed that piwi-interacting RNAs were aberrantly expressed in diverse type of cancers, few of them explored the detailed molecular mechanism of piRNAs in carcinogenesis, particular in ccRCC. In this study, differentially expressed piRNAs associated with ccRCC was selected by using piRNA-sequencing combined with analyzing TCGA data, from which piR-57125 was identified. PiR-57125 was found remarkably downregulated in ccRCC samples. Functionally, knockdown of piR-57125 promoted migration and invasion of ccRCC, while overexpression of piR-57125 suppressed ccRCC metastasis. In vivo lung metastasis model also confirmed the same results. CCL3 was identified as the direct target of piR-57125 which could reverse the inhibition effect of piR-57125 in ccRCC metastasis. Further studies revealed that piR-57125 modulated ccRCC metastasis through AKT/ERK pathway. Those data indicate that piR-57125 restrains ccRCC metastasis through directly targeting CCL3 and inhibiting AKT/ERK pathway, and could be a potential therapeutic target for ccRCC.

Project description:To define the role of MAGE-A1 in melanoma growth and metastasis, we performed RNA-seq analysis on MAGE-A1 overexpression (OE) and knockdown (KD) models in A375 human melanoma cell line. Our results revealed that overexpression of MAGE-A1 dramatically promoted proliferation, migration, and invasion of human melanoma cells in vitro and down-regulated of MAGE-A1 inhibited tumor cell proliferation and invasion. Furthermore, MAGE-A1 exerts its tumor promoting activity via activating including ERK-MAPK signaling pathway by RNA-seq analysis. mRNA profiles of MAGE-A1 over expression (OE), knockdown (KD), pcDNA-vector control, and pRNAT-scramble control in A375 cell line were generated using Ion torrent

Decreased TGFBR3/Betaglycan expression enhances the metastatic abilities of renal cell carcinoma cells through TGF-b-dependent and independent mechanisms

Project description:It is unclear how the loss of TGF-b signaling components affects metastatic abilities in clear cell renal cell carcinoma (ccRCC). In this study, we identified that low TGFBR3 expression in ccRCC cells enhanced primary tumor formation and lung metastasis. In the presence of TGFBR3, TGF-b2 decreased the aldehyde dehydrogenase (ALDH)-positive ccRCC cell population, in which renal cancer-initiating cells are enriched. Loss of TGFBR3 also enhanced cell migration in cell culture and induced expression of several mesenchymal markers in a TGF-b-independent manner. Increased lamellipodium formation by FAK-PI3K signaling was observed with TGFBR3 downregulation, and this contributed to TGF-b-independent cell migration in ccRCC cells. Taken together, our findings reveal that loss of TGFBR3 endows ccRCC cells with multiple metastatic abilities through TGF-b-dependent and independent pathways.

Expression data from Chinese renal cell carcinoma cells with FSTL1 knocked down

Project description:Clear cell renal cell carcinoma (ccRCC), the major histotype of cancer derived from kidney, is lack of robust prognostic and/or predictive biomarker and powerful therapeutic target. We previously identified that follistatin-like protein 1 (FSTL1) was significantly down-regulated in ccRCC at the transcription level. In the present study, we characterized, for the first time, that FSTL1 immunostaining was selectively positive in the cytoplasm of distal convoluted tubules. The expression of FSTL1 was significantly lower in ccRCC tissues than in adjacent renal tissues (P<0.001), as measured using immunohistochemistry in 69 patients with paired specimens, and lower in most ccRCC cell lines than in human embryonic kidney cells, as measured by quantitative RT-PCR. Multivariate Cox regression analysis in 89 patients with follow-up data showed that FSTL1 expression in tumors conferred a favorable postoperative prognosis independently, with a hazard ratio of 0.325 (95% confidence interval: 0.118-0.894). FSTL1 knockdown promoted anchorage independent growth, mobility, and invasion of ccRCC cell lines and promoted cell cycle from G0/G1 phases into S phase; while over-expression of FSTL1 significantly attenuated cell migration ability in ACHN cells. FSTL1 knockdown resulted in decreased expression of E-cadherin and increased expression of N-cadherin in ccRCC cell lines significantly, indicating that FSTL1 may attenuate epithelial to mesenchymal transition in ccRCC. Microarray assay indicated that NF-ÎºB and HIF-2Î± pathways were activated following FSTL1 knockdown in ccRCC cells. Our study indicates that FSTL1 serves as a tumor suppressor in ccRCC, up-regulation of FSTL1 in cancer cells may be a candidate target therapy for advanced ccRCC. RNA samples were collected from NRCC-shsiscramble, NRCC-shFSTL1-1 and NRCC-shFSTL1-2 cells. Then samples were hybridized to Affymetrix arrays for mRNA profiling.

Hedyotis diffusa-Sculellaria barbata (HD-SB) suppresses the progression of colorectal cancer cells via the hsa_circ_0039933/hsa-miR-204-5p/wnt11 axis

Project description:Our previous study confirmed that the combination of Hedyotis diffusa (HD) and Scutellaria barbata (SB) significantly inhibited colorectal cancer cells proliferation and the WNT signaling pathway. However, the exact molecular modulation remains unclear. In this study, colorectal cancer cells (SW620) were treated with 1 mg/mL HD-SB for 24 h, and high-throughput sequencing of circRNAs was performed. The level of hsa_circ_0039933 in three colorectal cancer cell lines (HT-29, SW620, and HCT116) was verified by qPCR. After transfection of hsa_circ_0039933 overexpression plasmids or small interfering RNAs, CCK8, apoptosis, cell migration, and cell invasion were utilized to evaluate the function of hsa_circ_0039933 in the progression of colorectal cancer cells. We identified hsa_circ_0039933, which was downregulated in HD-SB-induced colorectal cancer cells and positively related to colorectal cancer progression. In SW620 cells with relatively high expression of hsa_circ_0039933, interfering with the expression of hsa_circ_0039933 inhibited the proliferation, invasion, and migration of SW620 cells. In HCT116 cells with relatively low expression of hsa_circ_0039933, overexpression of hsa_circ_0039933 promoted the proliferation and invasion and migration ability of HCT116. Mechanistically, hsa_circ_0039933 targeted hsa-miR-204-5p to increase the expression of wnt11, leading to the activation of the Wnt pathway, thereby promoting the proliferation of colorectal cancer cells. This work revealed the potential molecular mechanism of HD-SB for the treatment of colorectal cancer, which was to inhibit the Wnt signaling pathway through the hsa_circ_0039933/hsa-miR-204-5p/wnt11 axis, then suppressing proliferation, migration, and invasion in colorectal cancer cell.
