The prognosis of glioblastoma remains poor despite intensive research efforts. Glioblastoma stem cells (GSCs) contribute to tumorigenesis, invasive capacity, and therapy resistance. Leucine-rich repeat-containing G-protein coupled receptor 5 (Lgr5), a stem cell marker, is involved in the maintenance of GSCs, although the properties of Lgr5-positive GSCs remain unclear. Here, the Sleeping-Beauty transposon-induced glioblastoma model was used in Lgr5-GFP knock-in mice identify GFP-positive cells in neurosphere cultures from mouse glioblastoma tissues. Global gene expression analysis showed that Gli2 was highly expressed in GFP-positive GSCs. Gli2 knockdown using lentiviral-mediated shRNA downregulated Hedgehog-related and Wnt signaling pathway-related genes, including Lgr5; suppressed tumor cell proliferation and invasion capacity; and induced apoptosis. Pharmacological Gli inhibition with GANT61 suppressed tumor cell proliferation. Silencing Gli2 suppressed the tumorigenicity of GSCs in an orthotopic transplantation model in vivo. These findings suggest that Gli2 affects the Hedgehog and Wnt pathways and plays an important role in GSC maintenance, suggesting Gli2 as a therapeutic target for glioblastoma treatment.Angiomotin (AMOT) is a membrane protein that is aberrantly expressed in a variety of solid tumors. Accumulating evidence support that AMOT is involved in the pathological processes of tumor proliferation, apoptosis, and invasion. Selnoflast However, the potential role of AMOT in the pathogenesis of diffuse large B-cell lymphoma (DLBCL) remains elusive. In the present study, we investigated the expression level and biological function of AMOT in DLBCL. AMOT expression was significantly reduced in DLBCL biopsy section, and low AMOT expression was associated with poor clinical prognosis. Overexpression of AMOT by lentivirus in human DLBCL cells induced cell viability inhibition concomitant with an increased percentage of cells in G1 phase and decreased percentage in S phase. Moreover, AMOT upregulation increased the sensitivity of DLBCL cells to doxorubicin. Furthermore, overexpression of AMOT led to reduced activation of key kinases for the DNA damage response (DDR). The above results indicated that AMOT acts as a tumor suppressor via inhibition of the DDR, thus reducing the viability while increasing the chemosensitivity in DLBCL. In summary, AMOT may be a novel potential target for DLBCL therapeutic intervention.Hepatocellular carcinoma (HCC) is a lethal malignancy with few effective options for therapeutic treatment in its advanced stages. While exosomal LINC00161 has been identified as a potential biomarker for HCC, its regulatory function and clinical values remain largely unknown. LINC00161 expressions in serum-derived exosomes from HCC patients and HCC cells were determined by qRT-PCR. The ability of proliferation, migration, and angiogenesis in HUVECs was assessed by MTT, Transwell, and tube formation. Luciferase reporter assay and AGO2-RIP assay were conducted to explore the interactions among LINC00161, miR-590-3p, and ROCK2. The level of ROCK signal-related proteins was examined by Western blotting and immunohistochemistry (IHC) assay. Subcutaneous tumor growth was observed in nude mice, in which in vivo metastasis was observed following tail vein injection of HCC cells. High levels of LINC00161 were detected in both serum-derived exosomes from HCC patients and the supernatants of HCC cell lines and were significantly associated with poor survival. Functional study demonstrated that exosomal LINC00161 derived from HCC-cells were significantly associated with enhanced proliferation, migration, and angiogenesis in HUVECs in vitro, all of which were effectively inhibited when LINC00161 was sliced with shRNA in HCC-cells. In vivo experiment showed that LINC00161 loss inhibited tumorigenesis and metastasis of HCC. Mechanistic study revealed that exosome-carried LINC00161 directly targeted miR-590-3p and induced its downstream target ROCK2, finally activating growth/metastasis-related signals in HCC. Exosome-carried LINC00161 promotes HCC tumorigenesis through inhibiting miR-590-3p to activate the ROCK2 signaling pathway, suggesting that LINC00161 may be used as potential targets to improve HCC treatment efficiency.Although chimeric antigen receptor CAR) T cell immunotherapies are an undeniable and unequivocal success, knowledge obtained from the monitoring of the first clinical trials targeting the CD19 antigen in B malignancies, either refractory/relapsed acute lymphoid leukemia (ALL) or lymphomas, contributed to the identification of tumor cell escape in about 30-50% of B-ALL. Resistance occurred due to loss of surface expression of the antigen (rCD19-) or to the early disappearance or inactivation of CAR T cells (rCD19+). In a recently reported clinical case, rCD19- relapse resulted from masking of the antigen by the CAR at the surface of B-ALL leukemia cells following the unexpected viral transduction of a leukemic cell present in the cytapheresis sample. The objective of this work was to reproduce this epitope-masking resistance model, in the context of acute myeloid leukemia (AML), based on our immunotherapeutic CAR T cell model targeting the accessory protein of the interleukin-1 receptor (IL-1RAP) expressed by herapy approach safe for application in a future phase 1 clinical trial.The outcome of prostate cancer (PCa) patients is highly variable and depends on whether or not distant metastases occur. Multiple chromosomal deletions have been linked to early tumor marker PSA recurrence (biochemical relapse, BCR) after radical prostatectomy (RP), but their potential role for distant metastasis formation is largely unknown. Here, we specifically analyzed whether deletion of the tumor suppressor CHD1 (5q21) influences the post-surgical risk of distant metastasis and whether CHD1 loss directly contributes to metastasis formation in vivo. By considering >6800 patients we found that the CHD1 deletion negatively influences metastasis-free survival in R0 patients (HR 2.32; 95% CI 1.61, 3.33; p  less then  0.001) independent of preoperative PSA, pT stage, pN status, Gleason Score, and BCR. Moreover, CHD1 deletion predicts shortened BCR-free survival in pT2 patients and cancer-specific survival in all patients. In vivo, CHD1 loss increases spontaneous pulmonary metastasis formation in two distinct PCa models coupled with a higher number of multicellular colonies as compared to single-cell metastases.
