Project description:Kindler syndrome (KS) is a rare genodermatosis resulting from loss-of-function mutations in FERMT1, the gene that encodes Kindlin-1. KS patients have a high propensity to develop aggressive and metastatic cutaneous squamous cell carcinoma (SCC). In this study, we show that loss of Kindlin-1 in a mouse model of cutaneous SCC leads to increased migration, invasion and degradation of collagen. Loss of Kindlin-1 increased tumor growth in vivo and in 3D spheroids, which was associated with the development of a hypoxic tumor environment and increased glycolysis. One of the most highly upregulated genes in Kindlin-1-depleted tumors was Mmp13, and the increased expression of MMP13 was responsible for driving the increased migration and invasion of the Kindlin-1-depleted SCC cells. These results provide evidence that Kindlin-1 loss in SCC can promote migration and invasion through the upregulation of MMP13, and offer novel insights into how Kindlin-1 loss leads to the development of a hypoxic environment that is permissive for tumor growth.

Project description:Kindlin-2, an integrin-interacting FERM-domain-containing protein, has been known to play critical roles for tumor progression. However, the role of Kindlin-2 in renal cell carcinoma (RCC) progression has not been reported. We aim to investigate the role of Kindlin-2 in the progression of RCC and the underlying mechanisms. To uncover the related pathway in which Kindlin-2 is involved to promote clear cell renal cell carcinoma progression, ACHN control and Kindlin-2-depleting cells were analyzed by Affymetrix GeneChip human Gene 1.0 ST Arrays. ACHN cells were transfected with control short hairpin RNA (shRNA) or Kindlin-2 shRNA. ACHN control and Kindlin-2-depleting cells cDNAs were hybridized to Affymetrix GeneChip Human Gene 1.0 ST arrays. Data were analyzed by Expression Console 1.4.1.

Project description:Aberrant expression of LncRNAs might be responsible for the HCC invasion and metastasis. we employed the LncRNAs microarray technology to study the LncRNAs expression profiles at genome-wide in hepatocellular carcinoma (HCC)tissue samples with early recurrence (less than 1 year, with invasion and metastasis out of liver) and late recurrence (longer than 2 years, without invasion and metastasis out of liver), which had different recurrent/metastatic potentials, by using normal liver tissue as control to screen the dysregulated LncRNAs which are potentially involved in the recurrence, invasion and metastasis process of HCC

Project description:As a humanized mouse antibody, SM5-1 can target a membrane protein of about 230kDa over-expressed in hepatocellular carcinoma (HCC), melanoma and breast cancer and it has been found to inhibit the progress of tumor cells. In this study, SM5-1 conjugated gold nanoparticles were prepared to study the antitumor efficacy in the treatment of HCC-LM3-fLuc tumor. The results showed that AU-SM5-1 could inhibit HCC-LM3 hepatocellular carcinoma cell proliferation up to 71.26% at the concentration of 0.5mg/ml contrast with SM5-1 and gold nanoparticles. In order to address the mechanism of the antiproliferative effects of AU-SM5-1, we examined the gene expression in HCC-LM3-fLuc tumor cells based on gene-chip screening. The gene chip results showed that some cycle-related and reactive oxygen species (ROS) related genes including up-regulated P21 and down-regulated duox2 and nox1 genes which were validated by real-time quantitative polymerase chain reaction (PCR).

Project description:BackgroundKindlin-2 is a member of the focal adhesion protein family that regulates invasion and metastasis in multiple malignancies; however, little is known about the role of Kindlin-2 in hepatocellular carcinoma (HCC) progression.MethodsImmunohistochemistry was used to investigate Kindlin-2 expression in 177 pairs of human HCC and adjacent liver tissue samples. The role of Kindlin-2 in the in vitro invasion and migration of HCC cell lines was evaluated in MHCC97H, LM3 and SMMC7721 cells. Microarray expression analysis was applied to explore the molecular mechanism through which Kindlin-2 promoted HCC progression. Quantitative real-time PCR and Western blotting were performed to verify the microarray results.ResultsHigh Kindlin-2 expression was found to significantly correlate with aggressive HCC clinicopathological features including tumor encapsulation, microvascular invasion, extrahepatic metastasis and poor prognosis. In vitro, Kindlin-2 knockout or knockdown inhibited HCC cell adhesion, migration and invasion, while ectopic Kindlin-2 expression promoted these processes. Importantly, Kindlin-2 activated Wnt/β-catenin signaling and increased β-catenin expression, especially levels of non-phosphorylated β-catenin, as well as two Wnt/β-catenin signaling pathway targets, Axin2 and MMP7. Kindlin-2 also induced a change in the expression profile of HCC cells, suggesting the cells underwent epithelial-mesenchymal transition. For example, the expression of the epithelial marker E-cadherin was downregulated, while the mesenchymal markers Vimentin, N-cadherin and Snail were upregulated.ConclusionKindlin-2 promotes HCC invasion, metastasis and epithelial-mesenchymal transition through Wnt/β-catenin signaling.

Project description:To investigation the role of PTH and Kindlin-2 in bone development, we performed single-cell RNA-sequencing. From Con-veh, Con-PTH, cKO-veh, cKO-PTH, we profiled more than 20k single cells, including multi-potent mesenchymal stromal cells (MSC), osteoprogenitors, osteoblasts, chondrocytes, fibroblasts, endothelial cells, smooth muscle cells, skeletal muscle cells, pericytes, and schwann cells. We found proportion of part of these cells were significant altered by PTH or Kindlin-2 loss, especially for MSC, osteoblast, chondrocyte, and fibroblast. Transcriptomic analysis revealed gene expression was dramatically regulated by PTH or Kindlin-2 loss.

Project description:Background: The presence of vascular invasion (VI) in pathology specimens has been widely described as closely linked to poor outcome in hepatocellular carcinoma (HCC) patients after tumor resection. Previous attempts have been conducted to achieve molecular markers or signatures to predict HCC recurrence in HCC. Here, we aim to develop a diagnostic model combining clinical and genomic variables able to detect the presence of VI prior to surgery and link it to survival estimation. Methods: Seventy-nine HCV related HCC samples from patients that underwent surgical resection as a treatment for HCC were subjected to Genome-wide gene expression profiling and a predictive model of vascular invasion was constructed. The model was tested in an independent-validation set of 153 fixed tissue samples of resected HCC. Quantitative RTPCR and inmunohistochemistry were performed in HCC samples to test a potential biomarker. Results: A 39-gene signature was able to accurately (72%) identify vascular invasion in HCC patients treated with resection. A model including tumor size and the signature is able to predict presence of VI with 85% accuracy in HCV-related HCC patients, and is able to exclude VI in up to 87% cases in HCC from all etiologies. Conclusions: Using the VI gene signature together with tumor size, VI can be successfully detected in HCC patients. The diagnostic model, integrated in a previously reported survival chart is able to provide an estimated survival for selected cases. Clinical implications of this fact are relevant to provide objective data to further apply expanded indication of curative treatments in HCC. Gene-expression profiling was performed using formalin-fixed, paraffin-embedded hepatocellular carcinoma tissues obtained at the time of surgical resection.
